(a) TITLE OF THE INVENTION
STAND OR WHEELED CART FOR RECYCLING SYSTEM
(b) TECHNICAL FIELD TO WHICH THE INVENTION RELATES
This invention relates to a system for the support and transportation of
containers
which are specially adapted to allow separation of recyclable materials at the
point of
origin without requiring excessive floor space, even though the present
invention is not
limited to such use. In particular, this invention relates to stands or
wheeled carts that
are manually movable by a user, and in particular to a recycling bin cart
having two or
more areas for receiving a different bin to reduce the amount of lifting
required to
accomplish recycling.
(c) BACKGROUND ART
With the increase in disposable products, there has been a significant
increase in
the solid waste generated per household. Efforts have been made to have such
waste
separated at the point of inception, i.e., in the home. These have not been
entirely
successful as it was considered to be inconvenient to separate the recyclable
materials
from the non-recyclable material. Recently there has been pressure upon home
owners
to use a plurality of containers at the home collection site where the trash
is collected so
that different parts of trash, e. g. , recyclable, may be separated from other
types, e. g. ,
non-recyclable. Thus, for example, people now separate paper in one container,
metals
in another container, glass in a third container and plastics materials in a
fourth
container, etc. The separation of these categories of trash enhances the
ability of a
community to recycle portions of the trash and thereby to reduce the trash
collection cost
of the community by the sale of the recyclable materials. However, the use of
a plurality
of containers has generated a need for a system to provide ease in separating
recyclable
materials from non-recyclable materials in the home without taking up
substantial space.
At the present time, the primary device for holding separated wastes is a bin
or
box. The homeowner is provided with colour-coded bins to enable separating the
recyclable materials, e.g., aluminum, paper, glass, and plastics materials
from each
CA 02271906 1999-OS-11
.
2
other. The recyclable materials are then collected on a weekly or bi-weekly
basis. Of
particular concern are heavy trash items, e.g., newspapers and glass. In the
case of
newspapers or glass, such bins often get very heavy and are difficult for
physically-
infirm or elderly people to lift and/or to carry from the house or apartment
to the curb
for pick-up. The recycling bins which are provided by the waste retrieval
company are
typically filled to the brim by the time they are picked-up for recycling.
Should a
homeowner miss a pick-up day, the weight of the bins can be even more
excessive. If
paper is to be recycled and is wetted by water, the bin weight can be very
heavy. For
larger families or the elderly, the weight of the bins may be excessive. Even
if an
individual is physically fit, the haste in movement of a weighted bin may
result in a
painful injury to the back if the weighted bin is moved incorrectly.
Furthermore, this problem of providing such bins is not limited to recycling
bins
and can be applied to most industries where items of like constituents may be
placed next
to each other. Many and varied styles and forms of racks, barricading
frameworks, and
the like, have been offered for use in connection with garbage cans and the
like. Cans
are used for general yard clean-up and other purposes, and are often loaded
too heavily
with trash and debris, and if they are of the larger sizes, they are unwieldy
and
sometimes dangerous to handle.
In addition, this problem exists in the mail rooms of some companies. Such
mail
rooms may have separate bins for first class, second class, third class, and
air
mail/packages. When a mail room clerk takes the items to a snail receiving
site, the
clerk typically stacks the bins on top of each other, which can result in
damage to the
contents of the mail. Similarly, the weight of multiple bins can exceed the
lifting
strength of an individual, resulting in injury to the worker.
Still another industry that requires bins of dissimilar material may be found
on
the manufacturing floor of a factory where bins can be used to hold parts for
an assembly
line. As with any industry where lifting is performed by the person, injury
may result
if the bin is lifted incorrectly during transfer. In addition, when multiple
bins are used
they may take up valuable floor space unless provisions are made for both
stacking of
the bins as well as access to the contents of the individual bins.

Still further problems exist in the carrying out of various household chores,
e.g.,
the periodic need to take care of the laundry, as well as other tasks. While
various
machines have been developed over the years to make this chore somewhat
easier, (e. g. ,
automatic washers and dryers), little has been done to ease the transport of
laundry and
laundry supplies to and from the washing and drying equipment. Conventional
baskets
which have been used for the carriage of laundry and clothing, are still used
in various
forms today. Such baskets have numerous disadvantages, e.g., the need to lift
and carry
them, their relative size and bulk which obstructs the view of the path of the
carrier
immediately in front, and the lack of any provision for carrying additional
supplies.
A number of combination recycling bins and transferring carts have been
disclosed in the prior art in an effort to address the transfer of recycle
bins. Among
them are the following:
U.S. Patent No. 2,855,210, patented October 7, 1958, by L. A. Joyce, provided
a cart rack for trash cans. The rack included a lower, horizontally-disposed,
endless
frame member which was provided at one side of its transverse center with a
first
coplanar T-shaped bracket. A second T-shaped brace was mounted within the
confines
of the frame member on the other side of the transverse center. The braces
functioned
to assist in reliably-supporting individual trash cans. An upper, horizontally-
disposed,
endless frame member was cooperatively-arranged in spaced parallelism directly
above
the lower frame member, and was provided, at a median portion thereof, with a
transverse brace which was located directly above the space existing between
the
respective T-shaped braces. A pair of front uprights were attached at their
upper ends
to a forward end portion of the upper frame member, and were connected at
their lower
end portions to a corresponding forward portion of the lower frame members,
and
depended below the frame member. They were provided with an axle, which
operatively-supported transporting wheels. A rear pair of uprights was
connected to the
respective rearward end portions of the upper and lower frame members and
depended
below the plane of the lower frame. A pair of diagonal braces was connected at
corresponding ends with the respective side members of the lower frame member
and had
rearward end portions underlying, and connected to, the lower ends of the legs
to provide
CA 02271906 1999-OS-11
4
feet for the legs. A U-shaped handle had arms straddling and rigidly connected
with
forward and rearward end portions respectively, of the lower and upper frame
members.
The lower forward end portions of the arms were connected with the respective
lower
end portions of the uprights.
U.S. Patent 2,921,694, patented January 19, 1960, by E. W. Decker et al.,
provided a knock-down display cart including a forwardly-projecting base and
an
upwardly-projecting back. The base was formed by a pair of laterally-spaced
frame
members extending along opposite sides of the base, and by an overlying panel
which
was secured to the members. The back was formed by a second pair of laterally-
spaced
frame members extending along opposite sides of the back, and by a discrete,
panel-like
reinforcing element. The reinforcing element had side margins which were
secured at
spaced points therealong to the frame members of the back. Means removably
secured
the end of the frame members of the base to the ends of the frame members of
the back,
thereby to provide for knock-down assembly. A wheel shaft extended
transversely
through the display cart and was supported by the base and back frame members
adjacent
to their interconnection. Wheels were removably secured to the shaft, thereby
to support
the display cart at the back of the base. Foot means were formed at the front
of the base
for otherwise supporting the display cart so that the base was generally-
horizontal and
the back was generally-vertical.
U.S. Patent 2,950,925, patented August 30, 1960, by K. O. Larson, provided
a push cart which included the combination of a first semicircular frame
component and
a second semicircular frame component which was secured to the first semi-
circular
frame component to form a circular frame member. The second semicircular frame
component had leg portions depending therefrom. A U-shaped lower support
member
had the outer free ends thereof connected to the lower ends of the depending
leg
portions. A pair of wheels was mounted at the point of connection of the leg
portions
and the free ends of the U-shaped support member. A handle member was
connected
to the first mentioned semicircular frame component.
U.S. Patent 3,111,333, patented November 19, 1963, by T. O. Marini, et al.,
provided a cart which was made up of a plurality of pairs of similar,
preformed, tubular
CA 02271906 1999-OS-11
elements. The cart included a pair of vertically-disposed, laterally-spaced,
similar side
frames, each of which consisted of a longitudinally-extending lower section
having an
upwardly-extending arm at each end thereof. The longitudinal lower sections
were
formed with a pair of spaced, downwardly-extending bends or rounded
protuberances,
5 which were connected together by an upwardly-extending medial hump or
reverse bend.
An elongated bolt, which constituted an axle, extended through apertures in
the bends
at the forward end of the side frames and had wheels which were rotatably
mounted on
each end thereof outwardly of the side frames. The bends at the rear end of
the side
frames constituted supporting legs when the cart was at rest. The upward-
extending arms
at the rear ends of the side frames were provided with a pair of similar,
aligned
extensions which terminated in rearwardly-extending handle portions. The upper
ends
of the side frame arms were all bolted to a rectangular frame which consisted
of a pair
of opposed, similar U-shaped members having the free ends thereof,which were
suitably
connected together. A base, which consisted of a pair of similar zig-zag or V-
shaped
members which were secured together back-to-back, was secured to, and between,
the
side frames, parallel to the upper rectangular frame, at the apices of the
upwardly-
extending medial connecting humps or reverse bends of the lower connecting
members
of the side frames. A medial, transverse, dividing and rigidifying X-shaped
frame,
which consisted of a pair of similar, diagonally-disposed crossing members was
detachably secured to, and between, the upper rectangular frame and the
medial,
connecting, upwardly-extending humps or reverse bends of the side frames.
U.S. Patent 3,280,988, patented October 25, 1966, by V. O. Bennett, provided
a portable can holder for supporting a row of garbage cans having side handles
and
removable lids. The portable can holder included a wheeled axle, and a
vertical
rectangular open frame which was carried by the axle at right angles thereto
adjacent one
end thereof. A pair of straps on opposite sides of the frame respectively
connected the
top of the frame with opposite end portions respectively of the axle to
maintain the
vertical inclination of the frame. A row of spaced hooks on the top of the
frame
received the side handles respectively of a row of cans, thereby suspending
the row of
cans in vertical position above the ground level and centred on the axle with
the lower
CA 02271906 1999-OS-11
6
peripheries of the cans engaging the bottom of the frame. Members on the top
of the
frame were disposed between respective pairs of cans. A pair of chains was
anchored
in each member and was connected with the lids of each pair of cans
respectively.
U.S. Patent 3,262,713, patented July 26, 1966, by J. Crawford, Sr., provided a
utility cart including a body having spaced upright members. A pair of wheels
was
provided at the front end portion of the body. A pair of rearwardly-extending
handle
bars was spaced laterally from each other for use in trundling the cart. The
handle bars
extended the full length of the body structure as well as rearwardly thereof.
Means were
provided for rigidly securing one handle bar to certain upright members of the
body
structure. A tie member was provided adjacent to the rigidly-secured handle
bar and was
secured to other upright members. A pivotal mounting was provided for the rear
end
portion of the other handle bar. A releasable latching provided connection
between the
front end portion of the pivoted handle bar and the body structure for
enabling the
respective handle bar to be rocked out of the way for loading and unloading
the cart.
When in latching engagement, the handle bar was firmly in position for
trundling the
cart.
U.S. Patent No. 3,380,752, patented April 30, 1968, by A. D. Goettl, et al.,
provided a utility cart including the combination of a frame and axles which
were freely-
movably-mounted on the frame in response to gravity and laterally relative to
the axis
of the wheel axle means. Wheels were rotatably mounted on the axles and were
adapted
to roll on the ground and to support the frame. A second means on the frame
supported
the wheel axles in an upper position so as to permit upward retraction of the
wheels and
to permit the frame to rest on the ground. The second means also was adapted
to
support the axles in a relatively lower position on the frame, such that the
wheels
supported the frame in a position above the ground. The second means had stop
means
for holding the axles in the lower position against upward vertical movement
on the
frame. The second means also had relief means which were disposed to permit
the wheel
axles to drop downwardly from the stop means and to permit the axles to move
laterally
away from the stop means and then upwardly to the upper position relative to
the frame,
when the frame was successively raised, then moved laterally of the wheel
axis, while
CA 02271906 1999-OS-11
7
the wheels touched the ground, and then lowered by gravity to rest the frame
on the
ground. The second means included wheel axle mounting plates. Further means
mounted the plates for vertical sliding movement and pivotal movement on the
frame.
The further means included L-shaped slotted structure. Pins were relatively-
movably-
mounted in the L-shaped slotted structures for movably supporting the mounting
plates
relative to the frame and for controlling disposition of the wheels in the
upper and lower
positions.
U.S. Patent No. 3,561,606, patented February 9, 1971, by I. A. Steward,
provided a holder for a garbage can, having handles on opposite sides, and a
removable
lid, each handle having inturned opposite end portions connected to the can.
The holder
included a post which was adapted to be erected on the ground. A support was
fixedly
carried by the post and extended laterally from one side of the latter, the
support
providing laterally-spaced arms. The outer terminal of each arm provided an
upwardly
extending hook. Reinforcing spacers connected the arms at the site of the
hooks. The
hooks engaged in a can handle adjacent opposite inturned ends of the latter,
to support
a can with an outward tilt, with its bottom bearing against the post. The
close adjacency
of the outer surface of the hooks to the inturned end portions of the handle
prevented
lateral movement of the can in its hook-supported position. A laterally-
extending second
support was carried by the post and was located above the can and its lid.
Means carried
by the lid and by the second support, anchored the lid to the latter in an out-
of the-way
position after it had been removed from the can.
U.S. Patent No. 4,521,030, patented June 4, 1985, by J. D. Vance, provided a
collapsible and slidable cart for the transport of articles on both horizontal
and oblique
surfaces. The cart included a pair of support members, each having a handle
portion at
the upper end and a wheel which was mounted for rotation at the lower end. At
least
one tray member for supporting articles extended outwardly from, and was
rotationally
connected to, the support members. Lock means which permitted or prevented the
rotational movement of the support members relative to the tray member
provided the
cart user with means to collapse the cart for storage. The support members had
a
curved, outwardly-extending lower end portion so that the wheels extended
outwardly
CA 02271906 1999-OS-11
8
from the remaining upper length. The curved lower ends had a low friction
contact
surface which permitted the cart to be transported on oblique surfaces. The
light-weight
tubular car construction permitted tray/support member rotation, as well as a
hinged, tray
perimeter member which permitted the cart to be collapsed into a second
configuration.
U.S. Patent No. 4,821,903, patented April 18, 1989, by J. K. Hayes, provided
a tubular metal cart for accommodating a plurality of bins which were
designated to
contain different types of recyclable trash which were filled in one location
and then were
transported to another location where the trash was picked up for disposal.
The cart had
an upper handle portion which was swept backwardly, a central vertical portion
and a
floor portion for bearing most of the weight of the individual trash bins.
Attached to the
upper part of the vertical central portion was a common lid which accommodated
the
plurality of bins at the collection site. The bin was braced at the rear
vertical central
portion and side bracing was also provided to connect the lower part of the
vertical
central portion with the horizontal part of the floor portion. Vertical foot
portions, each
of which could be provided with a rubber or plastic toe, extended from the
horizontal
floor portions of the bin.
U.S. Patent No. 5,192,092, patented March 9, 1993, by R. D. Benedette
provided a recycling bin cart having a pair of wheels and rigid vertical
support which
was coupled to at least two horizontally-supported shelves which were sized
and spaced-
apart to receive recycling bins with the lower shelf being located close to
the ground.
The cart was used to transport recycling bins containing different segregated
trash, e.g.,
newspapers, and was used to reduce the lifting of the recycling bins for
people who were
physically impaired.
U.S. Patent 5,445,397, patented August 29, 1995, by D. Evans, provided a
stackable refuse container system including multiple stackable containers,
each of which
could be designated for holding a particular recyclable material. The
containers were
vertically stacked and a cart was provided for transporting the stacked
assembly to and
from a curb. Each container included a removable lid, a front portion of the
lid being
hingably attached to provide an access to the container and a second portion
which was
CA 02271906 1999-OS-11
9
formed to engage and support a bottom of a complementary container. Each
container
also had sockets for receiving the feet of another container when a lid was
not used.
U.S. Patent No. 5,595,395, patented January 21, 1992, by A. C. Wilson,
provided a device for the stackable storage of various size bins used for
holding items,
e. g. , mail, recycling materials, and piece parts, allowing each bin to
rotate when the
device was tilted during movement of the bins so as to prevent spillage of
items placed
within the bins. The bins were maintained in a parallel and horizontal plane
to the
ground when placed in an upright and tilted position. Wheels and a handle of
the device
were predisposed to operate as a stand to assist in maintaining the positional
rotation of
each bin. The device was constructed of a rigid frame with two wheels and a
handle.
Brackets formed to the size of each bin were rotatably coupled to cantilever-
type supports
which projected outwardly from the front of the frame providing support for
each bin.
The brackets, which were used to support each bin, may support various size
bins, by
the use of bracket inserts or flexible straps. The frame could be constructed
of two rails
providing support of each end of a bin, allowing bins to be stacked in a
vertical position
to conserve floor space. The bins were spaced-apart, and provided for
rotational
movement to maintain the bins in a horizontal plane to the ground despite the
angular
positioning of the frame.
U.S. Patent No. 5,671,933, patented September 30, 1997, by R. D. Tucker,
provided a utility cart which included an open bin or container, with an open
lower
storage shelf which was disposed immediately below the upper bin. The lower
shelf
floor also served as a support for the cart when it was placed in a vertical
rest position.
Wheels were provided at the rearward portion of the cart, allowing the cart to
be moved
on the wheels with the entire weight of the cart being supported by the wheels
while in
transport, thus precluding any requirement for the user to lift any portion of
the weight
of the cart and/or its contents.
U.S. Patent 5,758,886, patented June 2, 1998, by S. M. Mayer, provided a
multiple container transportation system having a moveable frame for
transporting the
frame from one location to another, and at least one container unit which was
removably
secured to the moveable frame. The container unit was made up of a container
and a
CA 02271906 1999-OS-11
cover. The container had an open top portion of predetermined internal size
and a closed
bottom portion of a predetermined external size less than the predetermined
size of the
top portion. The top portion was angled from the back of the container to the
front of
the container such that the front of the container had a height less than the
height of the
5 back of the container. The cover was positionable upon the top portion of
the container
and was configured such that the top of the cover, when in position on the top
portion
of the container, was parallel to the bottom portion of the container so that
another
container can fit upon the cover of another container.
Canadian Patent No. 619,241, issued May 2, 1961, to J. T. Shakel, provided a
10 wheeled utility cart comprising a base frame structure having spaced,
longitudinally
extending side members. Traction wheels were supported by the frame structure.
An
upright carrier structure was longitudinally-adjustably-secured to the side
members and
had a fixed angular relation to the side members in all adjusted positions. An
accessory
structure was also provided. Means were provided for adjustably securing the
accessory
to the upright carrier structure.
Canadian Patent No. 715,434, issued August 10, 1965, to S. Mitty et al.,
provided a shopping cart which included a pair of vertically-spaced apart
containers. The
shopping cart included a folded corrugated paperboard body forming a
container. A
wheel assembly was secured to the bottom of the container at the rear thereof.
The
assembly also included a folded corrugated paperboard member with a horizontal
shelf,
and a trough extending below the shelf. A rod extended through the trough, and
a pair
of wheels were held on the ends of the rods. An inverted U-shaped wire handle
having
depending sides was slidably secured to assembly. A base rest was mounted at
the
bottom of the container at the front thereof.
Canadian Patent No. 750,829, issued June 17, 1967, to S. M. Stanley et al.,
provided a wheeled supermarket cart having two levels of storage shelves. The
cart
included a first receptacle having a bottom which was pivotally mounted on the
frame
for rocking movement from a forwardly-extending to an upright position by the
engagement of its forward end with another cart. Means acted on the first
receptacle to
apply a force thereto opposing the force of gravity. A gate was pivotally
mounted in the
CA 02271906 1999-OS-11
11
forward end of the first receptacle to close the end thereof in one position
and to form
an extension of its bottom in another position. A frame was provided at the
rear of the
first receptacle having spaced upwardly-extending rails forming an abutment
slide for
engagement by the forward end of the first receptacle of another car. A
transverse bar
extended between the spaced rails to form a handle.
Canadian Patent No. 954,159, issued September 3, 1974, to A. Trahlano,
provided a wheeled nestable car order cart which included a pair of vertically-
spaced
apart shelves. The cart included a frame having a bottom U-shaped portion
opening to
the front of the cart and was shaped nestably to receive the bottom U-shaped
portion of
the frame of a second cart. The cart included one shelf which was pivotably
mounted
at, or adjacent to, the base of the bottom, U-shaped portion of the frame and
which
normally extended toward the front of the cart. Means were provided at the
back of the
cart for guiding the shelf on the second cart to an upwardly extending
position when the
first cart is nested in the second cart. The second shelf was located above
the first shelf.
The second shelf was pivotably mounted on a vertical portion of the frame for
movement
between a horizontal position and an upwardly-extending position, when two
carts were
internested.
Canadian Patent No. 1,124,275, issued May 25, 1982, to R. P. Hutchman et al.,
provided a hand cart including a pair of side frames, which were spaced
laterally from
one another and which converged towards the front of the cart so as to permit
nesting
of the cart into the rear of another cart of similar configuration. Means
interconnected
the side frames adjacent the front of the cart, at the bottom of the side
frames. Means
interconnected the side frames at the rear of the cart and extended
transversely of the cart
at a level no lower than the uppermost extent of the side frames so as to
permit passage
thereunder of the side frames of another cart of similar configuration. At
least one, and
preferably two, inner basket supports were provided, including a pair of
laterally-spaced,
parallel rails which were spaced inwardly from respective ones of the side
frames and
which sloped from front to rear of the cart, the rails being connected to the
respective
side frames at the front of the cart. Suspension means suspended the rails
from the side
frames at the rear of the cart. The suspension means were configured and
positioned so
CA 02271906 1999-OS-11
12
as to permit the passage thereunder and to either side thereof of the side
frames and
basket support of another cart of similar configuration.
Canadian Patent No. 1,253,900, issued May 9, 1989, to J. F. Reinbold et al.,
provided a combination shopping cart and stock cart which included both upper
and
lower shelves. That cart included a wheeled chassis that provided a carton-
carrying
platform on which large packages, boxes or cartons could be carried. The cart
included
a pair of vertically-upright support posts which were carried by the chassis
at its rear
end, one of the posts being located on each side of the chassis. An inverted,
U-shaped,
vertical support member was also carried by the rear portion of the chassis,
well back
of the fore-and-aft mid-point of the chassis, with the bight of the inverted U
forming a
horizontal cross support member which was located forward of the upper ends of
the pair
of upright support posts that are located at the rear end of the cart. A
horizontal side
support member was provided on each side of the cart. This support member
connected
each of the rear upright support posts with the inverted U-shaped support
member,
preferably with the bight of the U-shaped member. This provided a side support
frame
on each side of the cart. Cantilever beams were pivotally mounted on the two
side
support frames to pivot, from a horizontal, operative position extending
forward of the
inverted U-shaped vertical support member, to a vertical, out-of the-way
position above
the U-shaped support member, and back again. The pivot axis of the pivoted
cantilever
beam was located rearward of the horizontal cross support member that was
forced by
the bight of the inverted U-shaped support member. The cart was completed by a
basket
defining a lading-carrying space. The basket was secured to the pivoted
cantilever beam
so as to be supported by that beam selectively in either its horizontal,
operative position
or its vertical, out-of the-way position. The rear end of the basket was
located at the
pivot axis of the mounting between the pivoted cantilever beam and the two
side support
frames.
Canadian Patent No. 1,308,134, issued July 7, 1988, to A. Le Marchand et al.,
provided a shopping trolley which was provided with an upper pivoting basket
and a
lower shelf. In the trolley, the upper trolley basket or tray was pivotally-
mounted on the
frame in order to be capable of withdrawing to a vertical position and thus
freeing the
CA 02271906 1999-OS-11
13
entire space located above the bottom platform. The pivotally-mounted basket
was closed
at the rear end by a flap which was freely mounted for pivotal displacement at
its top
edge. Its shape permitted engagement of the basket through the ~amilar rear
end of
another identical trolley. Guiding of this movable element into its position
of withdrawal
was performed by means of two vertical guides which extended against the rear
uprights
of the handle-bar frame and in which were engaged trunnions carried by the
sides of the
movable element, the horizontal axis of pivotal displacement of this element
being
defined by the trunnions. The two guides which were provided for the trunnions
of the
pivotally-mounted basket and which were disposed in two vertical planes
parallel to the
longitudinal axis were inclined in such a manner as to ensure that their lower
ends were
placed further forward than their upper ends, so that in the vertical position
of
withdrawal, the pivotally-mounted basket was placed between the two uprights
of the
handle-bar frame without projecting behind the handle-bar frame.
Canadian Patent No. 2,059,351, patented May 20, 1997, by J. A. Junta, et al.,
provided a compartmentalized basket truck. The basket truck included a base
platform
comprising a layer of longitudinal wood slats and a layer of transverse wood
slats which
were fixed together in known manner. The base platform had a caster at least
at each
corner thereof, each caster being mounted to the base platform by a steel
support plate.
A primary framework extended upwardly from the platform and included a
continuous
top rim which was elevated above the platform by a plurality of vertical
peripheral

The present invention in its broad aspects provides a stand or cart which is
adaptable for use by household residents engaged in recycling of newspaper,
mixed
paper, cardboard, plastic, tin and glass materials. Such stand or cart can
also be used
for garbage collection and for the collection of business waste paper. The
elderly and
handicapped will benefit from this stand or cart as well.
This stand or cart is primarily for the organization of recycling materials.
The
stand or cart can be made in many embodiments as above referred to accommodate
and
adapt to the many different and varied recycling programs which exist in
different cities
or geographical regions in North America and worldwide. It is designed to keep
recyclables in an organized setting by providing holders and storage areas for
both bag-
type and box-type styles of recycling containers, as well as providing space
for cardboard
items. These holders are sized to accommodate many known sizes of recycling
bags and
boxes. The stand, in one preferred embodiment, is made on a cart-style deck,
with
wheels, allowing easy transportation of recycling materials to the curb on
pick-up day.
The many embodiments of the stand accommodate different settings, e.g.,
residential
homes, mufti-family developments, apartments, restaurants, offices, etc.
The stand or cart of aspects of this invention is an improvement over the
prior art
devices, since it is compact and can handle many items in addition to the
conventional
"Blue Box" container for recyclable materials. It avoids the cumbersome
problem of
removing cans and putting them back and filling them in. The stand or cart of
aspects
of this invention can be used to support more than one bag, and is mobile.
The stand or cart of aspects of this invention handles both the blue recycle
bags
and the yellow recycle bags, as well as the blue box and also a garbage can,
all at the
same time on one convenient cart system. The various aspects of this invention
fit a
number of recycling bags and recycling boxes on the market and in use in
Canada and
U.S.A. They can handle two bags instead of one. The cart aspect carries the
bags to the
curb along with a garbage can and is mobile and is also capable of carrying a
blue
recycle box. Other aspects provide various additional accessories, e. g. , a
holder for
spare garbage bags and twist ties, cardboard holder, and removable skis.
Another aspect
is a child's toy model. Further aspects include wheel brakes, plastic lids of
various
CA 02271906 1999-OS-11
22
colours, handle grips, colour schemes, can crusher, extra garbage bag holder,
weighted
holder for bags, reflectors for safety, various number of wheels as
applicable, small
casters for upright model, skis for winter transport, canopy, aspects made of
plastic
model, or aluminum, or metal alloys or wood, twist tie holder, paper shredder,
handle
clips, cardboard holder, plastic or vinyl cover, means for connection of
additional carts,
and lids for the recycling bag holders. Still other aspects of the invention
provide
modifications and adaption to any garbage and recycling bag or box program in
use,and
for use in restaurants for table scrap clean up as well as in offices and
other businesses
for organized collection of recyclables and waste. For example, the base may
include
additional transverse and/or longitudinal members to reinforce the base to
enhance
stability and to enable castors to be added.
The use of the stand or cart of aspects of this invention helps clean-up and
organization of recyclable materials and garbage area. It also provides one
easy trip to
the curb on pick-up day. It makes the sorting of material easier and provides
a system
for sorting that can eliminate the need for last minute sorting and clean up
on pick up
day, and speeds-up curb pick-up by the collection company. The present
invention in its
various aspects is usable for the separation of recyclable materials and
mobile
transportation of these materials to the curb, saving time and reducing
clutter.
The benefits of the stand or cart of aspects of the present invention are that
it
offers convenience, is neat and tidy, save times, reduce work, improves safety
by
removing tripping and lifting hazards. It also reduces attraction of rodents,
cats and dogs
by keeping the garbage area clean. It also reduces the space required to store
unwanted
materials and reduces the curb-pick up time, and reduces litter at the curb by
containing
materials on the stand or cart, with the bags, boxes and garbage cans being
less
susceptible to being knocked or blown over.
The stand or cart of aspects of this invention may be provided in knock-down
form but, because of its structure, there are no difficulties in assembly,
since the
assembly is without the use of nuts and bolts.
