IMPROVED DRAIN CHAIN SYSTEMS AND
METHODS FOR CLEANING DRAINS
BACKGROUND
1. The Field of the Invention
The present invention relates to drain cleaning systems and methods for their
use.
2. The Relevant Technology
Many different types of drain cleaning systems have been developed to remove
hair and other debris from the plumbing of a shower or bath drain. Some
systems utilize
chemicals that are capable of breaking down clogged debris. Other systems
utilize
mechanical devices. And, some systems utilize a combination of chemical and
mechanical means.
A limitation experienced by some drain cleaning devices is that they can only
be
used after first removing the drain cap from the drain that is to be cleaned.
For example,
it may be necessary to position a mechanical device within the plumbing of the
drain in
order to grab and pull the debris from the drain. However, drain caps are
generally
configured as course filters that effectively prevent large physical objects
(such as
mechanical de-clogging devices) from being positioned within the drains until
after the
corresponding drain caps have been removed.
Other mechanical drain cleaning devices comprise filters that are positioned
immediately over and/or around the drain, to catch the debris before it enters
the drain.
These types of devices, however, can create potential hazards, since they
protrude up and
away from the drain cap.
Furthermore, even when these types of surface filters can be safely positioned
over the drain, they are typically unappealing to look at and require frequent
manual
cleaning.
Another problem with many existing systems is their expense, making them
impractical to replace and necessitating their frequent (and undesirable)
cleaning.
Chemical de-clogging systems have many drawbacks too. For instance, chemical
de-clogging solutions are somewhat expensive, particularly when considering
that they
only provide temporary results. There is also a general aversion to using
chemicals
because of the potential health risks associated with the use and storage of
the chemicals,
as well as the potential physical damage that can be caused by the misuse of
the
chemicals.

CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
For at least the foregoing reasons, there continues to be a need for new and
improved systems that are capable of de-clogging and helping maintain clean
drains.
BRIEF SUMMARY
The present invention is generally directed towards new and improved
mechanical systems that are capable of being used to de-clog and maintain clog
free
drains.
Many of the inventive systems of the invention utilize a chain that is capable
of
being positioned into a drain, sometimes through a hole in a drain cover, and
catching or
otherwise entangling or securing debris found in the drain. The chain can then
be pulled
out from the drain along with the entangled debris. In this manner, the chain
can be used
to de-clog or otherwise clean the drain. Notably, the chain can be pulled from
the drain,
through a hole in the drain cover, without even having to remove the drain
cover.
The chain, which is relatively inexpensive, can then be thrown away and
replaced. Alternatively, the chain can be cleaned and reused, if desired.
In some embodiments, the inventive de-clogging drain chain systems include a
relatively planar and decoratively shaped cap that is connected to the chain.
The
decorative cap also, preferably, includes one or more apertures or holes that
extend
through the cap to facilitate the passage of water through the cap as the cap
rests flat
against the drain cover and so as to prevent any unnecessary blockage of the
drain cover.
In some embodiments, the cap is also configured in a decoratively-shaped
pattern with
one or more decorative colors.
The chain is substantially flexible so as to be capable of being positioned
within a
plurality of differently-shaped drains and drain covers. In some embodiments,
the chain
is detachably connected to the cap, so as to facilitate easy removal and
replacement of
the de-clogging segment of chain. In other embodiments, the chain is
integrally
connected to the cap or substantially permanently attached to the cap so as to
lower
manufacturing costs and, in some instances, to facilitate the practical
replacement of the
entire de-clogging device. In other embodiments, the cap may include or be
replaced by
a suction cup, ring/sleeve or other securing device. This embodiment may also
be
designed to allow the de-clogging segment of the chain to be removed from the
cap and
replaced.
In some embodiments, an intermediate segment/connector is disposed between
and connected to each of the cap and the chain. This intermediate segment or
connector
2
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
can include a rigid stem, a flexible stem, a string, a wire, an intermediate
chain segment,
and/or any other type of connecting mechanism. This connector can be used to
maintain
a position of a de-clogging device on a drain cover, such as, for example, by
placing the
connector into one of the holes in the drain cover. This connector also
includes a
coupling element that operates as a detachable connection point for detachably
connecting the chain to the cap. In some instances, the chain also includes a
corresponding coupling element that is configured in size and shape to be
physically
coupled to and decoupled from the coupling element of the intermediate
connector.
The chain can be any type of chain having any type of links or interconnected
material made of metal, plastic, composites, or other materials which is
capable of being
used according to the descriptions of the invention. In some instances, the
chains are
simple interconnecting ball or bead chains, with a plurality of connecting
bead links. In
other embodiments, the chain includes a plurality of interlinking loops or
other types of
links. The links of the chain can be substantially the same in type and size
or the links
can vary in type and/or size along different portions of the length of the
chain.
In many instances, the hair comes in contact with the chain as the hair floats
at
the water level of a p-trap within the drain. Hair can become entangled in the
chain
along different portions of the chain as well, even away from a particular
water level.
In some embodiments, the chain is even further configured with a plurality of
interactive members positioned along the length of the chain to interact with
and catch
hair that falls into the drain.
After hair has gathered on the chain, the chain can be pulled out of the drain
by
pulling up on the decorative cap, for instance, which was previously lying
flat on or
proximate the drain cover. The chain can be thrown away, with or without the
decorative cap, by either leaving the chain connected to the cap or by
detaching the chain
from the cap. It can be hygienic to replace the chain, by detaching the chain
from the
decorative cap and by attaching a new chain to the decorative cap.
Disposable and replaceable chains configured to be attached to the decorative
cap
can be sold separately and/or as part of a kit with the decorative cap. A new
chain can
then be attached to the cap and positioned in the drain. This embodiment is
preferred
when the decorative cap is relatively nice and/or expensive as compared to the
chain, so
that it can be reused.
In some embodiments, the manufacture of the cap and chain can both be
relatively inexpensive, so as to facilitate the entire replacement of the cap
and chain

WO 2016/040066 PCT/US2015/048052
together. In other embodiments, the chain can be manually cleaned and the
chain can be
repositioned within the drain.

DETAILED DESCRIPTION
The present invention is generally directed towards new and improved
mechanical systems that are capable of being used to de-clog and maintain clog
free
drains. These systems are sometimes referred to herein as de-clogging devices,
de-
clogging systems, drain chain devices, drain chain systems, and sometimes even
more
generally as devices or systems.
Many systems of the invention utilize chains that are capable of being
positioned
within the plumbing of a drain to securely entangle and remove hair and other
debris
from the drain.
In some embodiments, the inventive systems are configured with a cap that is
placed on a drain cover and that is connected to a chain that passes through
the drain
plumbing via a hole in the drain cover. In these embodiments, the debris
secured by the
chain is pulled out of the hole in the drain cover with the chain. In other
embodiments,
the cap is configured to be integrated into the center of the decorative drain
cover, and
6
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
can be used for drains without covers, as a cover replacement, or configured
for use with
modified covers. One or more chains attached to the drain covers, or modified
covers,
extend into the drain to entangle the hair in the drain.
In many embodiments, the relatively inexpensive chain(s) can be cleaned of any
debris and reused, or replaced by detaching the used chain(s) from the cap.
Some drain chain systems of the invention will now be described with specific
reference to the illustrated embodiments shown in Figures 1-16C.
As shown in Figure 1, a drain chain system 100 is illustrated with a
decorative
cap 110, a chain 120 comprising a first/de-clogging segment of chain, and an
intermediate segment 130 that includes an intermediate segment of chain 140
and a
coupling element 150. The intermediate segment 130 is connected to the cap 110
at a
mounting point 160.
While the decorative cap 110 is presently shown as a butterfly, it will be
appreciated that the specific shape and colors of the decorative cap 110 can
vary to
accommodate different needs and preferences. The shape and color of the
decorative cap
110 can be helpful, in some embodiments, to facilitate detection of the cap
110, and to
distinguish it from the drain cover. This can be helpful, for instance, when
it is time to
clean the drain. The color and decoration of the cap can also provide desired
functionality by presenting a visual reminder to periodically clean the drain.
The color of the cap can be a persistent color or a color that changes over
time.
In one embodiment, the coloring of the cap 110 is provided as a water soluble
solution
that fades or that is dissolved over time such as, for instance, due to water
exposure. In
these embodiments, the color of the cap remaining after the solution
dissolves, or the
absence of the color of the cap as a result of the solution dissolving, can
indicate a
recommended time to clean the drain and to replace the system with a new
system.
The cap can be manufactured out of a variety of different materials, including
soft or hard PVC, other plastics, metals such as stainless steel or brass, or
other metals,
composites, ceramics, or even natural / biodegradable / green materials (e.g.,
bamboo,
coconut shells, sea shells, wood, husks, and so forth). The cap can also be
coated with a
rubber coating or another coating to facilitate securing the cap in a fixed
position over a
drain cover with friction of the coating.
The size of the cap can vary from less than an inch to many inches in
diameter,
e.g. 0.5 inches (1.27 centimeters), 1 or more inches (2.54 centimeters), 2 or
more inches
(5.08 centimeters), 3 or more inches (7.62 centimeters), 4 or more inches
(10.16
7
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
centimeters), 5 or more inches (12.7 centimeters), 6 or more inches (15.24
centimeters),
or even more. In most embodiments, the footprint of the decorative cap is
substantial
enough to extend over at least one entire hole and in some instances over many
different
holes in a drain cover when the cap is placed over the drain cover.
In some embodiments, the thickness of the decorative cap 110 is substantially
uniform, in a range from about 0.03125 inches, (0.0794 centimeters), to about
0.1875
inches, (0.47625 centimeters). In other embodiments, the thickness of the
decorative cap
110 is not uniform. The thickness of the decorative cap can also be less than
0.03125
inches, (0.0794 centimeters), or more than 0.1875 inches, (0.47625
centimeters), in some
embodiments.
Preferably, although not necessarily, the cap is relatively planar (e.g.,
having a
relatively flat top surface and a relatively flat bottom surface). This
embodiment can be
useful to minimize any potential tripping hazard. However, the cap can also
have a
curved or hemispheric shape, such that when the cap is placed on a flat object
(with the
bottom surface of the cap facing down), only a portion of the bottom surface
of the cap
will touch the flat object. This embodiment is beneficial when the system is
being used
with drain covers or drain openings that are not flat and such that the cap
substantially
conforms to the shape of the drain cover/opening.
The cap is also preferably formed with holes or apertures 170 that extend
entirely
through the cap (e.g., from the top surface to the bottom surface) to
facilitate the passage
of water through the cap as the cap rests substantially flat against the drain
cover/opening
and so as to prevent the cap from blocking the flow of water into the drain.
In some embodiments, the holes 170 in the cap are smaller than the holes in
the
drain cover, e.g., less than about 0.25 inches (0.635 centimeters) in
diameter, as shown in
Figure 1. With this configuration, the cap can help filter material from the
drain. In yet
other embodiments, the holes are greater and sometimes substantially greater
than the
holes in the drain cover.
Attention will now be directed to Figure 1 and a circle that is drawn around
the
cap 110. The circumference of the circle is defined, according to some
embodiments, by
a circumference of a circle having a diameter equaling a greatest measurable
diameter or
width of the cap at any point. While not numbered, the circumference of the
circle is
specifically identified in Figure 1.
In some embodiments, the uncovered portion of the cap within the circular area
defined by a circumference (i.e. those portions with holes or apertures) will
be great
8
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
enough to allow water to pass by/through the cap without causing substantial
resistance
against the flow of water through the drain when the cap is placed over the
drain. In
some embodiments, for example, the uncovered portion of the cap or the open
area
within the defined circumference is within a range of between about 10% and
70% of the
total area bounded by the circumference of the circle. In other embodiments,
the
uncovered portion of the cap is within a range of between about 20% and 60% of
the
total area bounded by the circumference of the circle. In other embodiments,
the
uncovered portion of the cap is within a range of between about 30% and 50% of
the
total area bounded by the circumference of the circle. In yet other
embodiments, the
uncovered portion of the cap is at least 40% of the total area bounded by the
circumference of the circle. However, the uncovered portion may be less than
10%
and/or greater than 70% of the total area bounded by the circumference of the
circle.
As demonstrated in Figures 1, 2, 5, 6 and 8, a decorative cap may be of
various
shapes and sizes. In one embodiment, the invention may include a flower-shaped
cap
that is directly connected to a chain, string or wire at a mounting point, as
shown in
Figures 10A through 10D. In other embodiments, the flower-shaped cap includes
an
intermediate segment that comprises a chain, string or wire which connects the
cap to
another chain, string or wire.
Figures 10A through 10D, for instance, illustrates an exemplary environment of
the drain chain system with a flower-shaped cap mentioned above. As
illustrated in
Figures 10A through 10D, the cap is configured in size and shape such that at
least a
portion of the holes in the drain cover will remain uncovered by the surface
of the cap
when the cap is placed over the drain cover. In preferred embodiments, at
least a
predetermined percentage of the holes in the drain cover will remain entirely
or at least
partially uncovered by the cap when the cap is positioned over the drain
cover. (e.g., the
predetermined percentage of the holes will be at least partially uncovered by
the cap or at
least the predetermined percentage of the total area that is defined by the
sum of all the
holes in the drain cover will remain uncovered by the cap when the cap is
positioned
over the drain cover).
In some embodiments, this predetermined percentage is within the range of 30%-
90% (e.g., 30%-90% of the holes are at least partially uncovered or at least
30%-90% of
the total area that is defined by the sum of all the holes in the drain cover
remain
uncovered by the cap when the cap is positioned over the drain cover). In
other
embodiments, this predetermined percentage is within the range of 40%-80%. In
other
9
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
embodiments, this predetermined percentage is within the range of 50%-70%. In
yet
other embodiments, the uncovered portion of the holes in the drain cover is at
least 60%.
In one alternative embodiment, the cap comprises a hook 172 that is configured
to rest on a structure of a drain cover that separates two holes of the drain
cover.
The chain 120, which is connected to the cap (either directly or indirectly
from
the bottom surface of the cap), contains a plurality of individual links that
are connected.
The chain 120 is substantially flexible so as to be capable of being
positioned within a
plurality of differently-shaped drains and drain covers. Even more
particularly, the chain
is configured in size and shape to pass through a hole in a drain cover,
having individual
links that are each defined by a size dimension (e.g., diameter, width and/or
height) that
falls within a range of about 0.125 inches (0.3175 centimeters) to about 0.25
inches
(0.635 centimeters). However, the size dimension of the chain links, in some
embodiments, can be less than 0.125 inches (0.3175 centimeters) and/or greater
than
about 0.25 inches (0.635 centimeters). The links of the chain can be
substantially the
same size, along the entire length of the chain, or vary along the length of
the chain (e.g.,
have a greater size at the portion of the chain that is furthest from the cap
or,
alternatively, in the middle portion of the chain, or a portion of the chain
that is nearest
the cap, relative to the rest of the chain).
The density of links per inch (2.54 centimeters) can vary from very few (e.g.,
less
than five) to very many (e.g., more than five).
The plurality of individual links in the chain, as well as each of the
connection
points between the links, provide the functionality of being able to catch and
secure hair
and other debris that falls down a drain. In many instances, the hair comes in
contact
with the chain as the hair floats at the water level of a p-trap within the
drain. In other
instances, the hair contacts the chain as the hair falls down the drain, even
before
reaching the water level of the P-trap.
The chains that are used by the invention can be any type of chain having any
type of links or interconnected material made of metal, plastic, composites,
or other
materials which is capable of being used according to the descriptions of the
invention.
In some instances, the chains are simple interconnecting ball or bead chains,
as shown in
Figure 1, with a plurality of connecting bead links. In other embodiments, the
chain
includes a plurality of interlinking loops or other types of links, as shown
in Figure 2.
The chain and links can also comprise materials other than metal and plastic.
For
instance, in some embodiments, the chain comprises a string, a rope, fabric,
or another
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
woven, fibrous or stranded material, composed of natural or synthetic
materials (e.g.,
PVC or Nylon string, shredded plastic, and so forth). In these alternative
embodiments,
the chain material is still sufficiently flexible to bend or collapse upon
itself, under its
own weight, without requiring external forces to cause the bending/collapsing.
In some alternative embodiments, a weight may be attached to a chain that is
less
dense than water to ensure that the chain does not float. In other
embodiments, a series
of weights may be attached along a chain that is less dense than water to
ensure that the
chain does not float.
Because of the functionality of the various links and link connection points,
it is
not necessary to provide any additional catching mechanisms along the chain.
However,
as disclosed in more detail below, additional catching mechanisms can still be
used with
the systems of the invention, if desired. For instance, in some embodiments,
the chain
120 is even further configured with a plurality of additional interactive
members that can
be used to further interact with and catch hair that falls into the drain.
This will be
described in more detail below with regard to elements 322, 324 and 326 of
Figure 3, as
well as element 222 of Figure 2.
The chain preferably has sufficient flexibility so as to bend and/or collapse
under
its own weight without requiring any external force to bend the chain, due at
least in part
to the flexible connections between the links. In other embodiments, at least
some
external force is required to bend the chain due to substantially rigid/tight
connections
between the links in the chain. When the chain is composed of a continuous
stranded/woven material, the flexibility is provided by the flexibility of the
material
and/or the weave of the material.
The flexibility of the chain 120 can be beneficial, as discussed below in
regard to
at least Figure 3, for allowing the chain 120 to be used in many differently
sized drains,
even when the chain 120 is longer than the length between a drain cover and
the bottom
of a p-trap, for instance.
The flexibility of the chain 120 is one distinguishing feature from the prior
art
devices, such as the hair trap disclosed in European Patent Application
EP1605105A1,
which utilize substantially rigid members for de-clogging drains. For
instance, the hair
trap disclosed in European Patent Application EP1605105A1 includes wires that
are
substantially rigid enough to maintain a bend at lift element (2), as well as
to retain the
bristles (4) that are held in place by the twining of the metal wires within
the elongated
body. This configuration requires additional bristles to catch the hair and
press it against
11
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
the body when the body is removed from the drain. This device fails to provide
any
links to a chain that are each capable of catching the hair and to flexibly
bend.
In some embodiments, (not shown), the chain of the present invention can also
be
replaced with a coarse or fibrous material (e.g., string, cord, a Velcro type
material or
any other material) that has the flexible properties of a chain and that also
includes a
plurality of different catch points along the material that are integral to
the material itself
(e.g., fibers of a string, hooks on a Velcro strip, etc.).
The chain 120 is preferably long enough to extend from the drain cover, on
which
it rests, to at least the water level in traditional drain plumbing (e.g., the
p-trap or other
plumbing). This length can be anywhere from a few inches (1-2 inches) (2.54-
5.08
centimeters) to many inches (12-24 or more inches) (30.48-60.96 centimeters).
In some
embodiments, the chain 120 can also be extended in length by a connector or
intermediate segment 130, as indicated above, that connects the chain 120 to
the
decorative cap 110 of the de-clogging system.
In many embodiments, the intermediate segment 130 is physically and rigidly
connected to the cap 110 and in such a manner that the connector extends
laterally away
from the bottom surface of the cap 110 in a fixed direction (e.g.,
substantially
perpendicularly away (defining an 80 to a 90 angle with the bottom surface),
or at an
obtuse angle from the bottom surface). In other embodiments, the connector is
hinged to
the cap or otherwise flexibly connected to the cap so that it can be
adjustably moved to
extend from a plurality of different directions from the bottom surface of the
cap and to
further accommodate placement of the cap on top of differently-shaped drain
covers.
In some embodiments the chain 120 is integrally connected to the decorative
cap.
The integral connection can be formed during manufacture in a casting,
drawing,
pressing, welding, gluing or other manufacturing process.
In some embodiments, the chain is mechanically coupled to the decorative cap
with a snap, ball and hook, ring and hook, clamp, clasp or other interlocking
mechanism
that is capable of providing the flexibility described above.
The chain 120 in Figure 1 is detachably connected to the decorative cap 110,
with
the intermediate segment connector 130, to facilitate easy removal and
replacement of
the chain with a different chain.
As shown, this connector 130 has an intermediate chain segment 140 that is
made
of the same type of links and material as chain 120. In other embodiments,
however, as
shown in Figures 4A, 5, 7C and 7D, the intermediate connector 130 can be made
of a
12
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
different material as well, including string, wires, fabric, or other
materials. The
intermediate connector 130 can be flexible or rigid.
In some embodiments, the intermediate segment comprises a flat, flexible
material that is thin enough to pass between a surface wall and the drain plug
(when the
drain plug is in a plugged or closed position) without breaking the seal
between the drain
plug and the surface wall of the tub or sink. Figure 9B illustrates one
embodiment of the
flexible intermediate segment (930) passing between a surface wall and the
drain plug
(when the drain plug is in a plugged or closed position) without breaking the
seal
between the drain plug and the surface wall of the tub or sink. Figures 9A and
9C show
related images of the drain chain system. While this embodiment can be
beneficial for
allowing a tub or siffl( to be plugged without breaking a seal, it will be
appreciated that
this does not mean that no water passes through the seal. Instead, it means
that the
intermediate segment is configured in size and shape (with a sufficiently thin
body) to
allow a seal to be substantially maintained by the drain plug when the drain
plug is in a
closed position, even though a small amount of water may pass there between.
The
intermediate segment can be manufactured out of a variety of different
materials,
including plastics and rubbers.
The length of the intermediate connector 130 can vary from less than 0.5
inches
(1.27 centimeters) to one or more inches (even more than 12 or 24 inches
(30.48-60.96
centimeters), as shown in Figure 4A).
The connector 130 can be connected to the chain 120 and the cap 110 by any
connection means, including, but not limited to welding, adhesives, friction,
mechanical
clamps or clasps, knots or other connection means. The diameter of the
connector 130
can be selected to be any appropriate diameter.
As indicated above, the chain 120 is detachably connected to the cap 110, so
as to
facilitate easy removal and replacement of the de-clogging segment of chain.
In these
embodiments, the connector 130 is equipped with a coupling element 150 or
other
connection object that operates as a detachable connection point for
detachably
connecting the chain 120 to the cap 110 indirectly through the intermediate
connector
130.
In the present embodiment, the coupling element comprises a dual slotted
receptacle that is sized and shaped to receive and hold a bead from chain 120
in one slot
and a bead from chain 140 in another slot. The chain 120 can be selectably
removed/detached from the coupling element 150 by pulling any bead of that
chain 120
13
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
that is contained within the slot of the coupling element 150 out of the
coupling element
150. Likewise, a new chain can be connected to the system 100 by placing a
bead/link
from the new chain into the coupling element 150.
Other types of coupling elements can also be used, some of which are described
below with specific regard to Figures 7B-7D and 7F.
In some embodiments, the chain 120 is made from the same material as the
decorative cap 110. It can be beneficial to manufacture the chain and cap out
of the
same material to minimize manufacturing costs in some circumstances.
In other embodiments, the chain 120 is manufactured out of a different
material
than the cap 110, including plastics, composites, ceramics, metals, or any
combination
thereof. This can be beneficial, for example, to facilitate the manufacture of
different
types of caps to provide for marketing opportunities for decorative caps of
various
configurations and to accommodate different preferences and needs.
Although not required, the cap 110 can be magnetized to help retain the cap in
a
particular location on or proximate the drain cover. Other attachment means
can also be
provided on the cap, such as hooks, clamps, tines (such as tines 172), suction
cups,
and/or other mechanical objects that are configured to position and retain the
cap over or
next to a drain cover in a desired placement. These attachment means (if
provided) are
preferably located on the bottom surface of the cap 110.
In some embodiments, the cap is directly connected to a suction cup, which
allows the cap to be suctioned to a tub, sink, or shower wall rather than
lying on top of a
drain cover, as shown in Figure 9B, for instance. This embodiment is
beneficial when
the system is being used in a tub, sink, or shower environment wherein it is
not practical
to place the cap directly over the drain because of a drain plug that is
positioned over or
within the drain. In these embodiments, the suction cup can be suctioned on a
sidewall
or other surface of a tub, sink, or shower, securely holding the chain within
the drain,
without causing any substantial obstruction to the operation of the drain.
As indicated above, hair can gather on the chain 120 when the chain 120 is
positioned in a drain. The chain 120 can then be pulled out of the drain, at
any desired
time, by pulling up on the decorative cap 110 which is lying flat on or
proximate the
drain cover. The chain 120 can then be thrown away, with or without the
decorative cap
110, by either leaving the chain connected to the cap 110 or by detaching the
chain 120
from the cap 110. The chain 120 can be detached from the decorative cap 110
and a new
14
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
chain can be attached to the decorative cap 110, such as, for example, by
using coupling
liffl( 150.
Figure 2 shows a different embodiment. In this embodiment, the drain system
200 includes a cap 210 that operates as a drain cover or that comprises a
specialized cap
212 that is physically coupled to the drain cover. As before, a chain 220 is
connected to
the cap 210/212 with an intermediary connector 230 that has an intermediate
chain
segment 240 and a coupling element 250. The chain 220 in this embodiment is
composed of a plurality of interlocking loops. The chain 220 can be removed by
opening a loop/hook on the coupling element 250 and sliding the chain 220 off
of the
loop/hook. A new chain can be added by hooking a link in the new chain with
the
loop/hook of the coupling element 250 and by closing the hook/loop to form a
closed
loop (if desired).
In this embodiment, the intermediate connector 230 also includes a stem or
rigid
mounting point 260 that extends perpendicularly away from the bottom surface
of the
cap 210/212. This embodiment can be useful for helping position the cap
210/212 in a
desired placement over a drain, by placing the mounting point 260 within the
hold of a
drain cover, for instance. This embodiment can also be useful for adding a
more robust
connection between the chain 220 and the cap 210/212. In some embodiments, not
shown, the coupling element 250 is directly connected to the mounting point
260,
without any intermediary chain 240.
The embodiment of Figure 2 also illustrates how the cap 210 has a plurality of
holes 270, as described above with regard to Figure 1. However, in this
embodiment, at
least some of the holes are tapered, namely holes 275, which are configured to
receive
screws 280 that can mount the cap 210 over a drain. The screws 280 can be
provided
with the system 200, as part of a kit, or they can be obtained separately.
The embodiment of Figure 2 can be useful for enhancing the functionality of a
drain cover. In particular, the filtering functionality of a drain cover can
be enhanced by
equipping the drain cover with a chain that can entangle or otherwise prevent
debris from
going down the drain. However, maintenance of this system can involve more
steps to
replace the chain. In particular, when the cap 210 is screwed into place over
a drain, it
will be necessary to remove the screws 280 from the cap 210 before the chain
can be
removed and replaced.
In some embodiments, however, the cap 210 is configured to securely fit over a
drain, with a friction fit or merely under the weight of gravity, without
using the screws
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
280 to secure the cap 210 in place. In such embodiments, it is relatively easy
to remove
the cap 210 from the drain and to clean or replace the chain 220.
In yet another embodiment, reflected by phantom line 214 and as suggested
above, a specialized cap 212 can be inserted into a modified drain cover,
which is
modified with a large central hole defined by line 214 and which is configured
in size
and shape to securely receive and couple to the specialized cap 212. For
example, the
specialized cap 212 can be configured to twist/screw into the modified cover
(with
corresponding threads in each of the modified cover and the specialized cap
212 (not
shown)), for a secure fit. Or, the specialized cap 212 can simply rest against
the
modified drain cover via a tapered fitting or a circumferential ridge, to be
held in place
against the modified cover by gravity.
The specialized cap 212 can include holes 270 that match the holes 270 in the
modified drain cover. Alternatively, the specialized cap 212 can omit any
holes or can
have a different type or configuration of holes than are present in the
modified cover, so
as to facilitate distinguishing the specialized cap 212 from the cover.
Although not presently shown, the specialized cap 212 can also include
mechanical elements that facilitate the attachment of the specialized cap 212
to the
modified cover. These elements can include any combination and configuration
of slots
and/or ridges that protrude into or away from the top surface of the
specialized cap and
that can be used to facilitate turning/screwing the specialized cap 212 into
the modified
cover or to facilitate grasping/lifting the specialized cap 212 away from the
modified
cover and without having to remove the cover or screws 280 holding the cover
in place.
Attention is now directed to Figure 3, which illustrates the drain chain
system
300 being used in a shower 302. In particular, the inventive system 300 is
positioned
over the drain cover 372 of a drain 394 that is formed into the floor 304 of
the shower
302. The drain cover 372 is presently secured to the floor 304 by screws 380.
While the cap 310 covers most of the drain cover 372, water is permitted to
pass
through holes 370a in the cap 310, on through into holes 370b in the drain
cover 372, and
down into the drain 394.
The cap 310 of the system 300 is positioned flat against the drain cover 372.
This
positioning occurs after the chain 320 is fed through one of the holes 370b in
the drain
cover 372. The cap 310 is at least partially held in place (e.g., vertically),
by the
mounting point 360 that extends perpendicularly away from the cap 310 and that
is
16
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
positioned through one of the holes 370b in the cover 372. Additional
mechanisms for
holding the cap in place can also be provided (not presently shown), as
described above.
Presently, the mounting point 360 is offset from a center of the cap 310.
However, in other embodiments, as shown in Figure 1, the mounting point 160
can be
connected to a centrally located region on the bottom surface of the cap 110.
The de-clogging system 300 shown in Figure 3 also includes an intermediary
connector 330 that includes an intermediate chain segment 340 and a coupling
element
350. As shown, the coupling element 350 and intermediary connector 330 are
used to
detachably connect the de-clogging chain 320 to the cap 310.
Notably, a portion 328 of the chain 320 is flexibly resting at the bottom of a
p-
trap 392 in the plumbing 390 of the drain 394. The flexibility of the chain
320 enables
the chain to be used in a variety of different drain systems. If the chain 320
is too long, it
simply gathers into a resting portion 328 at the bottom of the plumbing. This
is an
advantage over prior art systems that must be manufactured to different
lengths to
accommodate different drain lengths.
While the chain 320 can be any length, it is preferably at least long enough
to
reach the water line 380 of the p-trap 392 or other plumbing 390. One reason
for this is
because hair and other debris typically accumulate at the water level 380. It
is at the
water level 380 and beneath where the hair and other debris will then become
entangled
with the links in the chain 320.
Once the hair or other debris becomes entangled in the chain 320, the chain
320
can then be pulled up through the hole in the drain cover 372 with the
entangled debris.
In some embodiments, it has been found that the hair will become compressed
and pull
through the hole in the drain cover 372 with the chain 320, even without
requiring any
additional mechanisms for holding the hair in place (besides the links in the
chain). Hair
can often become entangled in the additional portion 328 of the chain 320 that
is resting
below the water level as the chain 320 is pulled out of the drain 394.
Sometimes, hair will also get caught along portions of the chain 320 that are
above the water level 380 within the drain. For this reason, it is sometimes
desirable to
provide a coupling element 350 that is very close to the cap 310 when the cap
310 will
be re-used with a new chain, so as to avoid having hair/debris to be caught by
the
intermediary connector 330, so as to minimize any cleaning of the intermediary
connector 330. Alternatively, or additionally, the intermediate connector 330
can be
shortened to a single mounting point 360, as in Figures 1, 6, and 8, which can
be
17
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
configured with a coupling element 350 directly connected to the mounting
point 360,
(not shown), and while omitting any intermediary connecting chain segment
(e.g.,
segment 340). For instance, coupling element 350 can be coupled directly to
mounting
point 360.
In other embodiments, as shown in Figures 5, 7C, and 7D, the intermediary
connector can be composed of a wire, cord or other material that is not likely
to catch the
hair as it passes through the drain.
In yet other embodiments, the intermediate segment 930 comprises a flat,
flexible
material which allows a drain chain system to be used in a tub or sink even
when
plugged, so as to not interfere with the drain plug functionality. This
embodiment is
beneficial when the system is used in a tub or sink because it allows the tub
or sink to be
plugged without breaking the seal of the plug, as shown in Figure 9B, while
still enabling
the cap to securely hold the chain in a desired position within the drain
(even when the
plug is used). The intermediate segment can be manufactured out of a variety
of
different materials, including plastic, rubber, and/or fabric.
Figure 3 also illustrates how the systems of the invention can be used in
combination with additional interactive members that can be used to further
interact with
and catch hair that passes through the drain. These interactive members (322,
324, 326)
are illustrated in Figure 3 as a Velcro-type material 322 (or another hook
type material),
as a rubber tine 324, and as a hook 326. Other types of interactive members
can also be
used, which can be made of flexible or rigid materials affixed to the chain
with an
adhesive, a mechanical coupling (friction tie), clasps, clamps, or any other
connection
means. These interactive members can be positioned along the chain 320 at the
anticipated water level 380 or at any other point(s) along the chain 320.
These
interactive members can have any desired length (e.g., less than or greater
than 0.25
inches (0.635 centimeters) or less than or more than 1 inch (2.54
centimeters)). The
thickness of the interactive members can also vary, from less than 0.125
inches (0.32
centimeters) to more than 0.25 inches (0.635 centimeters).
Interactive element 222, of Figure 2, represents another embodiment in which a
net, basket or other webbing structure 223, is attached to the chain to catch
hair in the
drain. This interactive element 222 can be directly connected to the chain
220, for
example, with the support strands 224. Alternatively, the support strands 224
can be
connected to coupling element 250.
18
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
In yet another embodiment, the interactive element 222 can be indirectly
connected to the chain, such that the support strands 224 are omitted. In this
embodiment, the chain simply passes through the center ring 226 of the
interactive
element 222 and stop 225 is used to keep the interactive element from falling
completely
off of the chain. In this embodiment, as well as the others, the interactive
element 222
can be manufactured out of a buoyant material that allows the interactive
element 222 to
float on the water level of the p-trap or other plumbing. The webbing
structure 223
(made of metal, string, fabric, plastic and/or any other material) is operable
to
catch/entangle hair and other debris at the water level. Such debris can also
become
entangled in the support strands 224 (when present).
When desired, the chain 220 can be pulled from the plumbing and the webbing
structure 223 is pulled up with the chain by way of the support strands 224
and/or the
stop 225, which can be discarded and replaced when the chain is replaced.
The diameter of the interactive element 222 can vary to accommodate different
needs and preferences. In some embodiments, the diameter of the interactive
element
222 is greater than 1 inch (2.54 centimeters) or greater than 2 inches (5.08
centimeters).
In other embodiments, the interactive element 222 is smaller than the hole
formed in a
modified drain cover, such as defined by line 214, for example.
Attention will now be directed to Figure 4A, which illustrates a drain chain
system 400a that is positioned in use with an overflow tub drain 496a that is
formed into
the side 404a of a tub 402. As shown, the drain chain system 400a includes a
chain 420a
that is connected to an intermediate segment 430a by way of a coupling element
450a.
The intermediate segment 430a in this embodiment comprises a chain 440a that
is also
connected to a cap 410a. Intermediate segment 430a can also comprise a string
or other
material. The cap 410a in this embodiment does not necessarily have holes
formed
through it and it is not necessarily flat, although it can be. The size and
ornamentation of
the cap 410a can vary to accommodate any need or preference. The cap 410a can
also be
buoyant in water or not.
This drain chain system 400a is positioned within the side tub drain 496a by
feeding the chain 420 through the opening 498a in the drain 496a. The chain
420 then
falls down through the drain plumbing 490a until it reaches the water level
480a of the p-
trap 492a or other plumbing. If there is extra chain 428a, it can flexibly
rest on the
bottom of the plumbing, as shown.
19
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
As water flows out of the bottom drain 494a that is formed into the tub 402
floor,
it will also pass by the drain chain system 400a that extends all the way into
the p-trap
492a region of the plumbing 490a. Although not common, it is also possible to
catch
any hair/debris that falls through the plumbing 490a from overflow tub drain
496a.
Accordingly, the drain chain system 400a can catch hair and other debris that
goes
through either drain in the tub. The chain 420a can then be pulled out of the
drain 496a,
at any desired time, by pulling the cap 410a which is held in place against
the drain 496a
by friction, by a hook (not shown), by magnets (not shown), suction cups (not
shown),
and/or any other attachment mechanisms connected to the cap 410a and that are
adequate
for holding the cap 410a in place against or near the drain and that are
configured to keep
the cap from passing through the opening 498a in the drain 496a.
Once the chain 420a is removed, it can be thrown away, with or without the
decorative cap 410a, by either leaving the chain 420a connected to the cap
410a or by
detaching the chain 420a and replacing it with a new chain.
Figure 4A also illustrates how a chain system can be used with the bottom
drain
294a of a tub, with the cap 412a resting on the drain cover and with the chain
422a
passing through the plumbing 490a into the p-trap 492a. The chain 422a can be
connected directly to the cap 412a, as described herein, or can be used with
an
intermediate segment, as also described herein.
Figure 4B illustrates another drain chain system 400b that is being used in a
tub
402. However, in this system 400b, the chain 420b is connected to a coupling
element
450b that is also connected to a drain plug 499b. The drain plug is operable
to plug the
plumbing 490b and to stop water from flowing out of the floor drain 494b when
the plug
is lowered into the plumbing by lever 497b and hinged arms 498b that are
connected to
the wall drain 496b. In this embodiment, the chain 420b can be removed from
the drain
496b by disconnecting the lever 497b from the drain 496b and pulling the
entire plug
499b and hinged arms 498b out of the drain 496b. Once removed, the chain 420b
can be
cleaned or replaced.
Figure 5 illustrates another drain chain system 500 of the invention. In this
embodiment, the intermediate segment 530 comprises a string or wire 540 that
is
interconnecting a star-shaped cap 510 and a bead chain 520. The coupling
element 550
in this embodiment comprises a knot tied between an end of the wire/string 540
and an
end of the chain 520. Accordingly, the coupling element 550 in this embodiment
can
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
also be viewed and include an end of the wire/string 540 and an end of the
chain 520
comprising one or more of the links/beads of the chain 520.
As in many other embodiments, this system 500 also includes a mounting point
or mounting member 560 that is configured to secure the intermediate segment
530 to
the cap 510. In this embodiment, the cap is also formed with a plurality of
holes 570.
The holes 570 can be similarly sized or sized differently (as shown).
Figure 6 shows a different embodiment of a drain chain system 600 that
includes
a chain 620 with a plurality of interconnecting loop links. This chain 620 is
directly
connected to a fish-shaped cap 610 at mounting point 660. Like the embodiment
of
Figure 5, this cap 610 also includes a plurality of differently sized holes
670. However,
unlike the embodiment of Figure 5, this system 600 does not include an
intermediate
segment. This embodiment can be useful when the manufacturing of the entire
system is
relatively inexpensive, so that it is practical to replace the entire system
600 once the
chain 620 has been pulled from a drain with entangled hair/debris.
Figures 7A-7F illustrate different configurations for connecting elements of
the
drain chain systems together. In Figure 7A, for example, a coupling element is
illustrated that comprises a dual-slotted receptacle 750a connected to a bead
link from an
intermediate segment 740a of chain, as well as another chain segment 720a
having bead
links capable of being selectably/detachably coupled to the coupling element.
The embodiment of Figure 7B includes a coupling element comprising a threaded
receptacle 756b on an intermediate segment 740b of chain, as well as an
another chain
segment 720b having a threaded prong 754b that can be threaded into the
threaded
receptacle 756b to selectably/detachably connect the lower chain 720b to the
intermediate chain segment 740b.
Figure 7C illustrates a coupling element comprising a closed loop 756c, on an
intermediate connector 740c, and a hook 754c on a chain segment 720c, which
are
configured in size and shaped to be selectably/detachably coupled together by
passing
the hook 754c through the loop 756c.
Figure 7D illustrates one embodiment of a coupling element of an intermediate
connector 740d comprising a closed loop 752d interconnected with an additional
closed
loop and hook connector 756d, as well as a closed loop 754d on a chain segment
that is
configured in size and shape to be selectably/detachably coupled together with
the closed
loop and hook connector 756d by passing the hook 757d through the loop 754d on
the
chain 720d. The hook 757d can be latched into the body of the closed loop and
hook
21
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
connector 756d, if desired, to further secure the chain 720d on the loop and
hook
connector 756d.
Another coupling element, not shown, can include magnets, wherein each of the
chain and the intermediate segment and/or cap have magnets.
Figure 7E illustrates one embodiment of a looped chain having two strands
(720e
and 726e) which are connected together by links of the chain at the
bottom/lower end
727e of the strands. The top portions (722e and 724e) of the strands can also
be
connected together or to a single object to form a closed loop in the chain.
In particular,
the top portions (722e and 724e) of the chain segments can be connected to a
cap or
intermediate segment of the inventive drain chain devices. This type of closed
loop can
be particularly useful to catch hair/debris because of the duplicated number
of links, as
well as the bottom 727e of the looped segments that forms an additional catch
mechanism.
This embodiment is well suited for use with the drain chain system of Figure
2,
which does not require the chains to pass through a drain cover hole. Instead,
the chains
can simply be passed into the plumbing of the drain. This embodiment can also
be used
with the specialized cap 212, such that the chains (two or more connected or
unconnected chain segments) can be connected to the bottom of the specialized
cap 212,
to be passed into and removed from the drain plumbing, without having to
remove the
modified drain cover from the drain.
Figure 7F illustrates an embodiment in which a coupling element includes a
claw
hook 754f that is configured to securely hold a loop, such as interconnecting
loop 756f,
in the hook. To remove the loop from the claw hook 754f, the latch in the hook
must be
mechanically opened first. This embodiment is useful for securely holding the
chain in
place and for quickly attaching one or more chains to the loop 756f, which can
be a
mounting point on the cap or a mounting element of an intermediate segment
that is
connected to the cap. The embodiments of Figures 7C and 7D can also be used to
connect multiple chains at a time directly to a cap (such as the specialized
cap 212) or
indirectly via an intermediate segment.
Figure 8 illustrates a packed kit containing a drain chain system 800,
including
decorative cap 810, an intermediate segment 840 connected to the cap with a
loop and
hook connector, and separate de-clogging chain segment 820. The intermediate
segment
840 also includes a coupling element 850, which can couple the chain segment
820 to the
intermediate segment 840. However, in the present illustration they are not
connected.

In some embodiments, the chain 820 is connected to the intermediate segment
840 prior
to packaging the kit. In other embodiments, the chain 820 is connected
directly to the
cap 810, omitting any intermediate segment. Presently, the chain segment
includes
interactive elements 824. However, these elements 824 can be omitted from
other
embodiments.
It should be appreciated that any combination and quantity of drain chain
elements from any of the described configurations can be packaged into the
kits of the
invention. For instance, the packaged kit can include any number of additional
elements,
as reflected by optional element(s). In one embodiment, the optional
element(s) include
additional chain segments that are capable of being used to replace the
illustrated chain
segment 820. These replacement segments can be the same as the illustrated
chain
segment 820 or can have different configurations.
The optional elements(s) can also include different caps, intermediate
segments,
coupling elements, and/or entire de-clogging systems. In some embodiments, one
or
more of the replacement chains are packaged and sold separately from the drain
chain
systems and/or caps.
The optional element(s) can also include instructions for using the drain
chain
system to clean a drain, to perform any of the functionality described herein,
and/or how
to obtain replacement chains.
The kit is presently shown to be packaged in a transparent envelope. However,
it
will be appreciated that different types of packaging can be used to package
the kits of
the invention, including envelopes, bags, boxes, tubes, or any other
packaging. The
drain chain systems of the invention can also be sold without any external
packaging.
Embodiments of the invention also extend to methods for manufacturing and
methods for using the drain chain systems described herein. For instance,
methods of the
invention include casting, cutting or stamping the caps and attaching chains
and/or
intermediate connectors to the caps. The intermediate connectors and/or chains
can be
attached directly to the caps by an adhesive, welding, riveting, clamping, or
with any
other attachment methodology. The chains can also be connected to the
intermediate
connector, when one is used in the system. Additional engagement members,
described
above (e.g., 824), can also be attached to the chain. As part of the assembly,
coupling
elements (as described above) can also be connected to the intermediate
connector and/or
chain.
23
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
Methods for using the drain chain systems of the invention, which have already
been described above, include obtaining a drain chain system, connecting the
chain to the
cap (if not already connected), either directly or indirectly with the
coupling element of
the cap or an intermediate connector. The chain is then put into a drain. In
some
embodiments, this includes feeding the chain through a drain cover hole or
through an
opening in a drain. In many embodiments, the chain is fed through the drain
until it
reaches the water level and/or p-trap of the plumbing. Then, the chain remains
in the
drain during use of the shower/tub. After a desired amount of time (e.g., a
week or
several weeks) or a desired amount of usage (e.g., a dozen uses, less than 100
uses, more
than 100 uses), the chain is pulled up from the drain. The chain can be pulled
from the
drain, for instance, by lifting or pulling on the cap away from the drain.
Then, in some
embodiments, the entire system is discarded. In other embodiments, the chain
is
removed from the system and replaced with a new chain. The new chain is then
placed
into the drain and the process is repeated.
In some embodiments, additional steps are also included, such as the steps for
fixedly attaching the cap to the drain when the cap is in the form of the
drain cover or a
modified drain cover (e.g., Figure 2).
As shown in Figure 9A, a drain chain system 900 is illustrated with a
decorative
cap 910, a suction cup 920, an intermediate segment 930, and a chain 940.
It will be appreciated that the specific shape and colors of the decorative
cap 910,
suction cup 920, and/or intermediate segment 930 can vary to accommodate
different
needs and preferences, as described above. The shape and color of the
decorative cap
910, suction cup 920 and/or intermediate segment 930 can be helpful, in some
embodiments, to improve aesthetic appeal and/or to facilitate detection of the
cap 910,
suction cup 920 and/or intermediate segment 930, and to distinguish the
invention from
the drain cover, side of the tub or side of the sink. This can be helpful, for
instance,
when it is time to clean the drain.
The color and decoration of the cap, suction cup, and/or intermediate segment
can also provide desired functionality by presenting a visual reminder to
periodically
clean the drain. For instance, the color of the cap, suction cup, and/or
intermediate
segment can be a persistent color or a color that changes over time. In one
embodiment,
the coloring of the cap 910, suction cup 920, and/or intermediate segment 930
is
provided as a water soluble solution that fades or that is dissolved over time
such as, for
instance, due to water exposure, or in response to a chemical reaction to the
water, soap
24
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
and or other environmental elements. In these embodiments, the color of the
cap, suction
cup and/or intermediate segment remaining after the solution dissolves, or the
absence of
the color of the cap, suction cup and/or intermediate segment as a result of
the solution
dissolving or chemically changing, can indicate a recommended time to clean
the drain
and to replace the system with a new system.
In this embodiment, the cap 910 is directly connected to the suction cup 920,
which allows the cap to be suctioned to a tub, sink, or shower wall, as well
as lying on a
drain cover. This embodiment is particularly useful in sinks and/or tubs that
use a pop-
up drain stopper, which are commonly used drains in homes, as shown in Figure
9B.
The suction cup can be connected to the cap 910 in various ways. In some
embodiments, the suction cup 920 may be selectably connected to the cap 910,
as a two-
part assembly, or as a single, integrated product. For instance, the
connection between
the suction cup 920 and the cap 910 can be formed during manufacture in a
casting,
drawing, pressing, ultrasonic welding, gluing, or other manufacturing process.
Likewise,
the suction cup 920 may be mechanically coupled to the cap with a snap, ball
and hook,
ring and hook, clamp, clasp or other interlocking mechanism. For example, the
suction
cup may have a threaded post on its top surface that can be screwed into the
cap.
In some embodiments, the cap 910 connected to the suction cup 920, may have a
total height (Figure 9A) that falls within a range of about 0.3 inches (0.762
centimeters)
to about 1 inch (2.54 centimeters), to facilitate manipulation of the suction
cup.
However, in other embodiments, the cap 910 connected to the suction cup 920,
may have
a total height that is less than 0.3 inches (0.762 centimeters) or greater
than 1 inch (2.54
centimeters), to provide a desired aesthetic appeal.
The intermediate segment 930 comprises a flat, flexible material which allows
a
drain chain system to be used in a tub or sink, even when plugged. This
embodiment is
beneficial when the system is being used in a tub or a sink that uses a pop-up
drain
stopper because it allows the tub or sink to be plugged without interfering
with the plug
functionality or breaking the seal caused by the plug when the plug is in a
closed position
(Figure 9B).
In some embodiments, the intermediate segment is configured in size, shape,
and
material to pass between the drain plug and drain wall without causing
substantial
interference with the seal caused by the plug when the plug is in a closed
position. The
intermediate segment can have, for instance, a thickness (Figure 9A) that
preferably falls
within a range of about 0.035 inches (0.0889 centimeters) to about 0.1 inches
(.254
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
centimeters). However, the thickness can also be less than 0.035 inches
(0.0889
centimeters) and/or greater than about 0.1 inches (.254 centimeters). The
thickness can
also be variable, varying along the length, such that the intermediate segment
has the
appearance of a wavy strip. In some embodiments, this can help assist the
draining of
water and hair down a drain.
The width of the intermediate segment (Figure 9C) is preferably within a range
of
about 0.2 inches (0.508 centimeters) to 0.8 inches (2.032 centimeters).
However, the
width can also be less than 0.2 inches (0.508 centimeters) and/or greater than
0.8 inches
(2.032 centimeters). The length of the intermediate segment preferably falls
within a
range of about 2 inches (5.08 centimeters) to about 12 inches (30.48
centimeters).
However, in some embodiments, the intermediate segment can also have a length
of less
than 2 inches (5.08 centimeters) and/or greater than 12 inches (30.48
centimeters).
While Figure 9A shows a side-view of this particular embodiment of the drain
chain system, Figure 9C demonstrates a top-view. In particular, 9C shows the
width of
the intermediate segment 930. In some embodiments, the width of the
intermediate
segment is at least 1.5 times greater than the thickness of the intermediate
segment. In
other embodiments, the width of the intermediate segment is at least two times
greater
than the thickness of the intermediate segment, or three times greater than
the thickness
of the intermediate segment. In yet other embodiments, the width of the
intermediate
segment is at least four times greater than the thickness of the intermediate
segment.
These embodiments allow for additional cross-sectional surface area and
tensile strength
of the intermediate segment, while still providing the aforementioned
functionality (e.g.,
not breaking the seal when the plug is in a closed position). However, in some
embodiments the thickness of the intermediate segment may be less than two
times
greater than the thickness of the intermediate segment. Alternatively, the
thickness of
the intermediate segment may be more than four times greater than the
thickness of the
intermediate segment to provide desired aesthetic appeal and/or mechanical
functionality.
The intermediate segment can be manufactured out of a variety of different
materials, including plastic, rubber, and fabric. In many embodiments, the
intermediate
segment 930 is physically and rigidly connected to the cap 910/suction cup 920
and in
such a manner that the connector extends laterally away from the bottom
surface of the
cap 910 in a fixed direction (e.g., substantially perpendicularly away
(defining an 80 to
a 90 angle with the bottom surface), or at an obtuse angle from the bottom
surface). In
26
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
other embodiments, the connector is hinged to the cap/suction cup or otherwise
flexibly
connected to the cap/suction cup so that it can be adjustably moved to extend
from a
plurality of different directions from the bottom surface of the cap 910
and/or the top of
the suction cup 920 and to further accommodate placement of the cap in
different areas
of a tub or sink.
The intermediate segment 930 can be connected to the chain 940, cap 910,
and/or
suction cup 920 by any connection means, including, but not limited to
welding,
adhesives, friction, mechanical clamps or clasps, knots or other connection
means. In
some embodiments, the intermediate segment may be molded over a segment of the
chain, the cap and/or the suction cup. The connection between the intermediate
segment
and the chain, cap and/or the suction cup can likewise be formed during
manufacture in a
casting, drawing, pressing, ultrasonic welding, gluing, or other manufacturing
process.
In one embodiment, the coupling is formed by a ring that is positioned around
a portion
of the suction cup and which is attached to the intermediate segment and which
enables
the intermediate segment to freely rotate around the suction cup. Other types
of coupling
elements can also be used, some of which are described below with specific
regard to
Figures 7B-7D and 7F.
In some embodiments, the intermediate segment 930 is detachably connected to
the cap 910, suction cup 920, and/or chain 940 using any of the connectors
discussed
herein. In other embodiments, the intermediate segment 930 is permanently
connected
to the cap 910, suction cup 920, and/or chain 940 using any of the connectors
discussed
herein.
While Figure 9A demonstrates a direct connection between the intermediate
segment 930 and the chain 940, in some embodiments, the intermediate segment
930
may be connected to an intermediate segment connector, which indirectly
connects the
intermediate segment 930 to the chain 940 (See intermediate segment connector
130 in
Figure 1). In some embodiments, the intermediate segment 930 may be molded
over the
intermediate segment connector. In other embodiments, the intermediate segment
connector is detachably connected to the chain 940, to facilitate easy removal
and
replacement of the chain with a different chain.
While the intermediate segment is currently shown to have a rectilinear body
shape, it will be appreciated that the intermediate segment can also comprise
a
substantially cylindrical or oval shaped cross-section, such that the
intermediate segment
is shaped more like a cord than a flattened strip of material.
27
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
In some embodiments, the intermediate segment connector may have a chain
segment that is made of the same type of links and material as the chain 940.
In other
embodiments, however, as shown in Figures 4A, 5, 7C, and 7D, the intermediate
segment connector can be made of a different material as well, including
string, wires,
fabric, or other materials. The intermediate segment connector can be flexible
or rigid.
As indicated above, the chain 940 can be detachably connected to the
intermediate segment 930 or the intermediate segment connector, so as to
facilitate easy
removal and replacement of the de-clogging segment of chain. In some of these
embodiments, the intermediate segment 930 and/or the intermediate segment
connector
are equipped with a coupling element (see intermediate segment connector 130
and
coupling element 150 in Figure 1) or other connection element(s) operating as
a
detachable connection point for detachably connecting the chain 940 to the cap
910
indirectly through the intermediate segment connector(s).
The coupling element may comprise a dual slotted receptacle that is sized and
shaped to receive and hold a bead from the intermediate segment connector in
one slot
and a bead from the chain 940 in another slot (See Figure 1). The chain 940
can be
selectably removed/detached from the coupling element by pulling any bead of
that
chain 940 that is contained within the slot of the coupling element out of the
coupling
element. Likewise, a new chain can be connected to the system 900 by placing a
bead/link from the new chain into the coupling element. In other embodiments,
the
connections between the intermediate segment 930, the intermediate segment
connector,
and the chain 940 may be through any mechanical means or manufacturing process
for
coupling.
The chain 940, which is connected to the intermediate segment 930, contains a
plurality of individual links that are connected. The chain 940 is also
substantially
flexible so as to be capable of being positioned within a plurality of
differently-shaped
drains.
The plurality of individual links in the chain, as well as each of the
connection
points between the links, can provide the functionality of being able to catch
and secure
hair and other debris that falls down a drain. In many instances, the hair
comes in
contact with the chain as the hair floats at the water level of a p-trap
within the drain. In
other instances, the hair contacts the chain as the hair falls down the drain,
even before
reaching the water level of the p-trap.
28
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
The chains that are used by the invention can be any type of chain having any
type of links or interconnected material made of metal, plastic, composites,
or other
materials which is capable of being used according to the descriptions of the
invention.
In some instances, the chains are simple interconnecting ball or bead chains,
as shown in
Figure 1, with a plurality of connecting bead links. In other embodiments, the
chain
includes a plurality of interlinking loops or other types of links, as shown
in Figure 2.
The chain and links can also comprise materials other than metal and plastic.
For
instance, in some embodiments, the chain comprises a string, a rope, fabric,
or another
woven, fibrous, or stranded material, composed of natural or synthetic
materials (e.g.,
PVC or Nylon string, shredded plastic, and so forth). In these alternative
embodiments,
the chain material is still sufficiently flexible to bend or collapse upon
itself, under its
own weight, without requiring external forces to cause the bending/collapsing.
In some alternative embodiments, a weight may be attached to a chain that is
less
dense than water to ensure that the chain does not float. In other
embodiments, a series
of weights may be attached along a chain that is less dense than water to
ensure that the
chain does not float.
Because of the functionality of the various links and link connection points,
it is
not necessary to provide any additional catching mechanisms along the chain.
However,
as disclosed, additional catching mechanisms can still be used with the
systems of the
invention, if desired. For instance, in some embodiments, the chain 940 is
even further
configured with a plurality of additional interactive members that can be used
to further
interact with and catch hair that falls into the drain, as was discussed with
regard to
elements 322, 324, and 326 of Figure 3, as well as element 222 of Figure 2.
The intermediate segment 930 and the chain 940 are preferably long enough to
extend from where the invention rests (drain cover or sink, shower, or tub
wall), to at
least the water level in traditional drain plumbing (e.g., the p-trap or other
plumbing).
This length can be anywhere from a few inches (1-2 inches) (2.54-5.08
centimeters) to
many inches (12-24 or more inches) (30.48-60.96 centimeters).
As indicated above, hair can gather on the chain 940 when the chain 940 is
positioned in a drain. The chain 940 can then be pulled out of the drain, at
any desired
time, by pulling up on the cap 910 and/or suction cup 920 which are lying flat
on or
proximate the drain cover. The chain 940 can then be thrown away, with or
without the
decorative cap 910, by either leaving the chain connected to the cap 910 or by
detaching
the chain 940 from the cap 910. The chain 940 can be detached from the
decorative cap
29
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
910 and a new chain can be attached to the decorative cap 910, such as, for
example, by
using coupling element 960.
Some additional views of the flat strap and suction cup embodiments of a drain
chain system 1000 are shown in Figures 10A through 10E. Figure 10A depicts a
side
view of a drain chain system 1000 comprising a cap 1010 and a suction cup 1020
that are
selectably coupled together. An intermediate segment 1030 connects the cap
1010 to a
chain 1040. While the connection between the suction cup 1020 and the cap 1010
is
presently shown to include a threaded connection, with the threading being
formed
internally to the suction cup and externally to the cap (best seen in Figure
10C), it will be
appreciated that in other embodiments, the threading can be reversed. For
instance, the
cap 1010 may also have a hollowed stem with internal threads that match
external
threads of a suction cup 1020 stem (which replaces the current mounting stem
of the
suction cup). Other temporary and selectably detachable connections between
the
suction cup and the cap include press fits and slotted couplings. In yet other
embodiments, the connection between the suction cup and the cap are more
permanent,
such as with an adhesive.
Figure 10B is a top view of the drain chain system 1000 and Figure 10C is a
side
cross-sectional view of the drain chain system 1000. Figure 10D is a
perspective
exploded view of the drain chain system 1000 showing the intermediate segment
1030
being connected to the cap 1010 by the connection between the cap 1010 and the
suction
cup 1020.
Figures 11A and 11B are top and side views, respectively, of one embodiment of
the intermediate section 1130 of a drain chain system (having an irregular
body shape),
and illustrating relative dimensions of the intermediate section 1130 and a
connection
1142 between the intermediate section 1130 and the chain 1140.
It will be appreciated that while the connection between the intermediate
section
and the chain is presently shown by over-molding plastic material from the
intermediate
section to the chain, other connection mechanisms can also be used, including
adhesives
and hooks.
While different material may be used to manufacture the intermediate section,
in
some embodiments, the intermediate section may be manufactured out of low
density or
high density polypropylenes. Nylons and other plastics can also be used.
Attention is now directed to Figures 12 and 13. In these figures, a cap 1210
is
configured with a reduced diameter 1244. The reduced diameter 1244 of the cap
1210,
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
in these embodiments, is within a range of about .25 inches (.63 centimeters)
and about
1.0 inch (2.54 centimeters). Thus, the diameter 1244 is preferably smaller
than about
one inch (2.54 centimeters) and, more preferably, smaller than about .75
inches (1.905
centimeters) and, even more preferably, about .5 inches (1.27 centimeters).
This
embodiment is useful for facilitating passage of water through a drain cover,
without
obstructing very many holes on the drain cover. In some embodiments, the cap
obstructs
or covers no more than one hole entirely. In other embodiments, the cap
obstructs or at
least partially covers no more than 9 holes. The cap 1210 may be sized to
resist passing
through the hole in the drain cover, while an intermediate segment 1230 may
extend
through the holed in the drain cover and connect to a chain 1220.
Figures 12 illustrates a small diameter cap 1210 connected, via the
intermediate
segment 1230, to a chain 1220 with at least one interactive element 1224 that
can be used
to further interact with and catch hair that falls into the drain, as was
discussed with
regard to elements 322, 324 and 326 of Figure 3, as well as element 222 of
Figure 2.
In this embodiment, the cap 1210 is tapered into a conical shape and formed
out
of a flexible material (e.g., rubber, LDPE, or another flexible material) that
allows the
cap to be selectably deformed and squeezed between portions of a drain cover,
with a
rim that rests on the drain cover and a small tab for removing the cap 1210
from the
drain cover, when desired. As shown, the intermediate segment 1230 may also
include
ribbing or textured flanges to help secure the cap into a desired placement.
Figure 13 illustrates a top view of an embodiment of the drain chain system
1300
after the chain 1320 is fully passed through the drain cover, with the cap
1310 resting on
a portion of the drain cover. The cap 1310 is fully positioned into a hole of
the drain
cover, with the rim 1312 of the cap 1310 resting against the drain cover, and
with the tab
of the cap partially extending over another hole of the drain cover.
Figure 13 better illustrates the rim 1312 and the tab 1314 that can be used to
remove the cap 1310 from a secured location. This view also illustrates how
the cap
1310 can be substantially hollow to further facilitate the flexible nature of
the cap 1310.
However, in other embodiments, the cap 1310 can be substantially solid, but
composed
of a flexible and low density material that still enables the cap 1310 to be
flexibly
squeezed into a desired placement in a drain cover hole.
The dimensions of the rim 1312 and tab 1314 can vary to accommodate any need
or preference. In some embodiments, the rim 1312 extends less than about .5
inches
(1.27 centimeters) away from the cap body (and side walls). In other
embodiments, the
31
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
rim 1312 extends less than about .25 inches (0.635 centimeters) away from the
cap body.
In yet other embodiments, the rim 1312 extends less than about .125 (0.32
centimeters)
inches away from the cap body. The tab 1314 can also vary in size from about
.125
(0.32 centimeters) inches to about .5 inches (1.27 centimeters) in length
(extending away
from the outer edges of the rim 1312).
Figures 14A and 14B illustrate another drain chain system 1400, which is
comprised of a ring or sleeve 1410, a tab 1412, a coupling element 1430 and a
chain
1420.
It will be appreciated that the specific shape and colors of the ring 1410
and/or
tab 1412 can vary to accommodate different needs and preferences. The shape
and color
of the ring 1410 and/or tab 1412 can be helpful, in some embodiments, to
facilitate
detection of the ring 1410, alert a user when it is time to clean the drain
and/or facilitate
easier removal of the system 1400. The color and particular shape of the ring
1410
and/or tab 1412 can also provide desired functionality by presenting a visual
reminder to
periodically clean the drain.
The color of the ring 1410 and/or tab 1412 can be a persistent color or a
color that
changes over time. In one embodiment, the coloring of the ring 1410 and/or tab
1412 is
provided as a water soluble solution that fades or that is dissolved over time
such as, for
instance, due to water exposure or in response to a chemical reaction. In
these
embodiments, the color of the ring 1410 and/or tab 1412 remaining after the
solution
dissolves, or the absence of the color of the ring as a result of the solution
dissolving, can
indicate a recommended time to clean the drain and to replace the system with
a new
system 1400.
The ring 1410 and/or tab 1412 can be manufactured out of a variety of
different
materials, including soft or hard PVC, other plastics, metals such as
stainless steel or
brass, or other metals, composites, ceramics, or even natural / biodegradable
/ green
materials (e.g., bamboo, coconut shells, sea shells, wood, husks, and so
forth).
The diameter of the ring 1410 can vary from less than an inch to many inches
(e.g. 0.5 inches (1.27 centimeters), 1 or more inches (2.54 centimeters), 2 or
more inches
(5.08 centimeters), 3 or more inches (7.62 centimeters), 4 or more inches
(10.16
centimeters), 5 or more inches (12.7 centimeters), 6 or more inches (15.24
centimeters),
or even more) to accommodate the size of a drain in which the drain chain
system 1400
is placed.

WO 2016/040066 PCT/US2015/048052
In some embodiments, the height of the ring 1410 is substantially uniform and
may be in a range from about 0.1 inch (0.254 centimeters) to about 1 inch
(2.54
centimeters). However, in other embodiments, the height of the ring 1410 can
also be
less than 0.1 inch (0.254 centimeters) or more than 1 inch (2.54 centimeters).
In yet
other embodiments, the height of the ring 1410 may not be uniform. This is
particularly
true when the ring 1410 includes the tab 1412, as shown in Figures 14A and
14B. In
some embodiments the tab 1412 of the ring 1410 may have a height that falls
within a
range of about 0.5 inch (1.27 centimeters) to about 1.5 inches (3.81
centimeters).
However, in other embodiments, the height of the tab 1412 of the ring 1410 may
be less
than 0.5 inch (1.27 centimeters) or more than 1.5 inches (3.81 centimeters).
In some embodiments, the thickness of the ring 1410 and/or tab 1412 is
substantially uniform, within a range from about 0.035 inches (0.0889
centimeters), to
about 0.15 inches (0.381 centimeters). In other embodiments, the thickness of
the ring
1410 and/or tab 1412 is not uniform. The thickness of the ring 1410 and/or tab
1412 can
also be less than 0.035 inches (0.0889 centimeters), or more than 0.15 (0.381
centimeters) inches, in some embodiments.
The diameter of the ring 1410 can also be the same (from the top of the
ring/sleeve to the bottom), or it can vary. For instance, the diameter may be
reduced
(e.g., tapered) at the bottom to facilitate placement of the ring 1410 within
a drain.
Alternatively, the diameter may be reduced (e.g., tapered at the top) to
facilitate removal
of the system 1400.
The ring/sleeve embodiment is particularly useful in tubs that use "lift and
turn"
or "pop-up" drain plugs, which are commonly used in hotels and apartment
complexes.
The ring 1410 allows the system to function even when a lift and turn drain is
installed
and plugged, as the ring can rest below/around the plug, within the drain, and
in such a
manner as to position the chain within the drain without interfering with the
drain plug
(or drain seal) at all.
The chain 1420 can be connected to the ring 1410 in various ways. In some
embodiments, the ring 1410 may be connected directly to the chain 1420. In
these
embodiments, the chain 1420 may be mechanically coupled to the ring 1410 with
a snap,
ball and hook, ring and hook, clamp, clasp or other interlocking mechanism.
In some embodiments, the chain 1420 may be connected to the ring 1410 using
an adhesive. In other embodiments, the ring 1410 and the chain 1420 may be
manufactured as one continuous piece, the ring 1410 being molded over the
first few
33
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
segments of chain 1420. The connection between the ring 1410 and the chain
1420 can
be formed during manufacture in a casting, drawing, pressing, ultrasonic
welding, gluing
or other manufacturing process.
In many embodiments, the ring 1410 may be connected to the chain 1420 and/or
an intermediate segment (substantially similar to those shown in Figures 1, 2
and 5) that
is physically and rigidly connected to the ring 1410 and in such a manner that
the
connector extends vertically down and away from the bottom of the ring 1410 in
a fixed
direction. In other embodiments, the connector is hinged to the ring or
otherwise
flexibly connected to the ring 1410 so that it can be adjustably moved to
extend from a
plurality of different directions from the wall of the ring 1410 to further
accommodate
placement of the ring 1410 in various drain environments.
The chain 1420 and/or intermediate segment can be connected to the ring 1410
and/or each other by any connection means, including, but not limited to
welding,
ultrasonic welding, adhesives, friction, mechanical clamps or clasps, knots or
other
connection means. The connection between the chain 1420 and/or intermediate
segment
and the ring 1410 can likewise be formed during manufacture in a casting,
drawing,
pressing, ultrasonic welding, gluing, or other manufacturing process.
In some embodiments, the ring 1410 may be molded over an intermediate
segment. In other embodiments, the ring 1410 may be detachably connected to
the chain
1420 and/or intermediate segment in any of the ways mentioned above. In yet
other
embodiments, the ring 1410 may be permanently connected to the chain 1420
and/or
intermediate segment in any of the ways discussed above. The intermediate
segment
may also include a connector (see intermediate segment 130 in Figure 1) which
is
detachably connected to chain 1420, to facilitate easy removal and replacement
of the
chain 1420 with a different chain.
As described herein (see Figures 1, 2 and 5), the intermediate segment
connector
may have a chain segment that is made of the same type of links and material
as chain
1420. In other embodiments, however, as shown in Figures 4A, 5, 7C and 7D, the
intermediate segment can be made of a different material as well, including
string, wires,
fabric, or other materials. The intermediate segment connector can be flexible
or rigid.
As indicated above, the chain 1420 may be detachably connected to the
intermediate segment connector, so as to facilitate easy removal and
replacement of the
de-clogging segment of chain 1420. In these embodiments, the intermediate
segment
includes an intermediate segment connector, which is equipped with a coupling
element
34
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
(see coupling element 150 in Figure 1) or other connection object that
operates as a
detachable connection point for detachably connecting the chain 1420 to the
ring 1410
indirectly through the intermediate segment connector.
In some embodiments, the coupling element comprises a dual slotted receptacle
that is sized and shaped to receive and hold a bead from the intermediate
segment
connector in one slot and a bead from the chain 1420 in another slot. The
chain 1420 can
be selectively removed/detached from the coupling element by pulling any bead
of that
chain 1420 that is contained within the slot of the coupling element out of
the coupling
element. Likewise, a new chain can be connected to the system 1400 by placing
a
bead/link from the new chain into the coupling element.
The chain 1420, which may be connected to the intermediate segment or directly
to the ring 1410, contains a plurality of individual links that are connected.
The chain
1420 is also substantially flexible so as to be capable of being positioned
within a
plurality of differently-shaped drains.
The plurality of individual links in the chain 1420, as well as each of the
connection points between the links, can provide the functionality of being
able to catch
and secure hair and other debris that falls down a drain. In many instances,
the hair
comes in contact with the chain 1420 as the hair floats at the water level of
a p-trap
within the drain. In other instances, the hair contacts the chain 1420 as the
hair falls
down the drain, even before reaching the water level of the P-trap.
The chains that are used by a system according to the present disclosure can
be
any type of chain having any type of links or interconnected material made of
metal,
plastic, composites, or other materials which is capable of being used
according to the
descriptions of the invention. In some instances, the chains are simple
interconnecting
ball or bead chains, as shown in Figure 1, with a plurality of connecting bead
links. In
other embodiments, the chain includes a plurality of interlinking loops or
other types of
links, as shown in Figure 2. The chain and links can also comprise materials
other than
metal and plastic. For instance, in some embodiments, the chain comprises a
string, a
rope, fabric, or another woven, fibrous or stranded material, composed of
natural or
synthetic materials (e.g., PVC or Nylon string, shredded plastic, and so
forth). In these
alternative embodiments, the chain material is still sufficiently flexible to
bend or
collapse upon itself, under its own weight, without requiring external forces
to cause the
bending/collapsing.
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
In some alternative embodiments, a weight may be attached to a chain that is
less
dense than water to ensure that the chain does not float. In other
embodiments, a series
of weights may be attached along a chain that is less dense than water to
ensure that the
chain sinks.
Because of the functionality of the various links and link connection points,
it is
not necessary to provide any additional catching mechanisms along the chain.
However,
as disclosed, additional catching mechanisms can still be used with the
systems of the
invention, if desired. For instance, in some embodiments, the chain 1420 is
even further
configured with a plurality of additional interactive members 1424 that can be
used to
further interact with and catch hair that falls into the drain, as was
discussed with regard
to elements 322, 324 and 326 of Figure 3, as well as element 222 of Figure 2.
The chain 1420 is preferably long enough to extend from the ring 1410 to at
least
the water level in traditional drain plumbing (e.g., the p-trap or other
plumbing). This
length can be anywhere from a few inches (1-2 inches) (2.54-5.08 centimeters)
to many
inches (12-24 or more inches) (30.48-60.96 centimeters).
As indicated above, hair can gather on the chain 1420 when the chain 1420 is
positioned in a drain. The chain 1420 can then be pulled out of the drain, at
any desired
time, by pulling up on the tab 1412 which is lying proximate the drain cover.
The chain
1420 can then be thrown away, with or without the ring 1410, by either leaving
the chain
connected to the ring 1410 or by detaching the chain 1420 from the ring 1410.
The chain
1420 can be detached from the ring 1410 and a new chain can be attached to the
ring
1410.
As shown in Figure 14B, in some embodiments, the ring 1410 is configured with
a tab 1412 that extends upwardly from a back portion of the ring 1410, and in
which the
ring 1410 has an opening at a front portion of the ring 1410 between arms of
the ring
1410 that enable the ring 1410 to flex open and closed. The ring 1410 also
includes a
coupling element, such as a mounting section or a catch/hole in the ring,
which is
positioned below the plane defined by the circumference of the ring 1410, but
substantially aligned with a radial center of the ring 1410. This coupling
element can
also be connected to or include spokes, connect the mounting section or catch
to the ring
and hold this mounting section/catch at the appropriate position. The chain
connects
direction to this mounting section or catch with over-molding, a press fit, a
snap fit, an
adhesive or one or more attachment mechanisms.

CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
It will be appreciated that the ring, including the spoke members and other
parts
of the ring can be manufactured out of plastics, metals, rubbers or any other
materials
that are suitable to keep their form when placed within a drain.
During use, the ring is positioned against the inner walls of a drain,
directly
beneath a drain cover or drain plug, so as to not interfere with the drain
plug, but so as to
be securely positioned without falling down the drain.
Referring now to Figure 15, in some embodiments, a drain chain system 1500
may include a cap configured as or replaced by a hook 1510. In this
embodiment, the
hook 1510 includes a hook-shaped member having a securing arm 1546 and an
intermediate segment, such as a stem 1530, to secure the hook 1510 around a
drain
cover. During use, the securing arm 1546 and the stem 1530 pass through
different holes
in the drain cover to secure the hook 1510 in place, with the chain 1520 down
in the
drain (below the drain cover).
As also shown, the intermediate segment may include a connection mechanism
1542 that can securely attach the hook 1510 to the chain 1520.
Different diameters and material flexibility can be used for the hook 1510 or
hook shaped member to accommodate different needs and preferences. Likewise,
the
diameter defined by the hook 1510 can also vary, as can the distance between
the
securing arm 1546 and the stem 1530.
In one embodiment, the diameter of the hook 1510 is within the range of about
.125 inches (0.3175 centimeters) and .75 inches (1.905 centimeters). In
other
embodiments, the hook diameter is within a range of between about .25 inches
(0.63
centimeters) and .5 inches (1.27 centimeters), or between about .125 (0.3175
centimeters) and .5 inches (1.27 centimeters) or between about .5 inches (1.27
centimeters) and .75 inches (1.905 centimeters).
The distance between the securing arm 1546 and the stem 1530 is at least
partially smaller than the diameter of the hook 1510 to facilitate securing of
the hook
1510 in a desired placement on a drain cover.
Although not required, the securing arm 1546 can flare outwardly at its end,
to
further facilitate placement of the hook 1510 on a drain cover.
In some embodiments, the hook 1510 is manufactured out of a flexible plastic.
In
other embodiments, the hook 1510 is manufactured out of a spring steel or
other metal.
The connection mechanism 1542 can include over-molding, as described above
in other embodiments, friction fits, snap fits, hooks, adhesives or any other
connection
37
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
mechanism. In the present embodiment, the connection mechanism 1542 is formed
by
wrapping a portion of the hook 1510 material around one or more segments of
the chain
1520.
In some alternative embodiments, as shown in Figures 16A through 16C, for
example, the hook of the drain chain system can also be replaced by a cap
having a
plurality of lateral members extending from a central point, such as shown
with regard to
the drain chain systems of Figures 16A through 16C. The plurality of lateral
members
may be formed into the shape of a Y, an X, a T, a straight bar, or another
shape, in which
the cap support structure has a minimalistic footprint. In Figure 16A, the cap
is shown as
a Y-cap 1610a. For example, the Y-cap 1610a may have three members extending
transversely from the center of the Y-cap 1610a. In some embodiments, the
three
members may extend at equally space angular intervals from one another. In
other
embodiments, the three members may extend at irregular intervals from one
another. In
Figure 16B, the cap is shown as an X-cap 1610b. For example, the X-cap 1610b
may
have four members extending transversely from the center of the X-cap 1610b.
In some
embodiments, the four members may extend at equally space angular intervals
from one
another. In other embodiments, the four members may extend at irregular
intervals from
one another. In Figure 16C, the cap is shown as a straight bar 1610c. However,
as
indicated, other caps can have the shape of a T or any other similar shape.
This may enable more water to pass through the drain, while the supporting cap
1610a, 1610b, 1610c rests on the drain cover. In Figures 16A through 16C, the
cap
1610a, 1610b, 1610c is formed by a thin wire, made of metal or plastic. The
diameter of
the wire can be less than about .125 inches in diameter. The width of the caps
1610a,
1610b, 1610c, from end to end (for the bar) or from a first extremity to an
opposing or
second extremity will preferably fall within the range of about .25 inches and
2 inches.
However, in other embodiments, the length can be greater than 2 inches or
within a range
of about .5 inches and 1.5 inches, to accommodate different needs and
preferences.
Referring now collectively to Figures 16A through 16C, a connection mechanism
1642a, 1642b, 1642c is positioned relatively central to the body of the wire
caps 1610a,
1610b, 1610c, which connects the chain 1620a, 1620b, 1620c to the wire cap.
The
connection mechanism can be an adhesive connection, a molded or welded
connection,
or a mechanical connection (e.g., hook, clip, etc.). The connection mechanism
1642a,
1642b, 1642c may also be included as part of the intermediate section 1630a,
1630,
1630c (presently limited to the connection mechanism). In other embodiments,
for
38
CA 02925886 2016-03-30
WO 2016/040066 PCT/US2015/048052
instance, the intermediate section 1630a, 1630, 1630c includes and/or is
configured as
one of the intermediate sections described above in reference to Figures 1-
11B.
