TITLE
PROTECTIVE ENCLOSURE FOR A WINDOW COVERING CORD
TECHNICAL FIELD
[0001]
The present disclosure generally relates to corded window coverings.
More particularly, but not exclusively, the present disclosure related to
protective
enclosure for a window covering cord.
BACKGROUND
[0002] A corded window covering is an indoor window covering that is
equipped with at least one cord such as shades, slats, blinds including roller
blinds
and the like coverings. The cord used can be a band, a rope, a strap, a
string, a
chain, a wire or any other like component.
[0003]
The Government of Canada has assessed that children are at risk
of strangulation from corded window coverings (CWCs). Indeed, the average
fatality
rate is slightly more than one child death per year. A Health Canada risk
assessment on CWCs to assess the strangulation hazard concluded the cords for
CWCs continue to present an unreasonable risk of injury or death to your
children.
Accordingly, the Government of Canada proposed updated regulatory requirements
to these products to provide stronger protection for children. These new
regulations
would restrict the length of reachable cords and the size of loops that can be
created
by a cord in order to help eliminate the risk of strangulation. The term
"reachable"
respect to a cord, refers to the part of the cord that any person can touch
when the
corded window covering has been installed, whether the window covering is
fully
opened, fully closed or in any position in between. The term "loop" means a
shape,
Date Recue/Date Received 2020-11-20
2
the majority of which is formed by a reachable cord, that creates a completely
bounded opening.
[0004]
The Regulations restrict the length of accessible cords and the size
of loops that can be created. The Regulations require that any cord that can
be
reached must be too short to wrap around a one-year-old child's neck (i.e. not
more
than 22 cm in length) or form a loop that can be pulled over a one-year-old
child's
head (i.e. not more than 44 cm in circumference) when subjected to the gradual
application of force attaining 35 N. Cords that cannot be reached must remain
unreachable throughout the useful life of the product. Cords that are shielded
or
.. made inaccessible are not subject to the length and loop requirements,
though they
must remain inaccessible. Cords that can be reached cannot exceed 22 cm in
length
or create a loop greater than 44 cm in circumference when they are at rest,
whether
the product is fully covering the window, fully open, or at any position in
between.
Reachable cords may be any length or have loops of any size so long as a pull
force
.. of more than 35 N is required to draw them out. When this force is removed,
cords
that can be reached must retract to less than 22 cm in length or 44 cm in
circumference.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
[0022] Generally stated and in accordance with an aspect of the present
disclosure, there is provided a corded window covering system. The system
comprises a window cover for selectively covering a window. An actuator
assembly
is in operative communication with the window cover. A cord defining top and
bottom ends thereof and vertically extends along a given length of the window.
The
cord is connected to the actuator assembly for being pulled to actuate the
actuator
assembly to impart window covering and uncovering movements to the window
cover. A protective enclosure vertically extends along a length of the cord
for
enclosing an upper portion of the cord. A bottom portion of the cord remains
exposed. The exposed bottom portion of the vertical cord comprises a length of
not
more than about 22 cm and/or forms a loop of not more than about 44 cm in
circumference.
[0023]
With reference to Figures 1 and 2, there is shown corded window
covering 10 in the form of a roller blind.
[0024]
The roller blind 10 comprises a roll 12 which is comprised of a window
cover in the form of a sheet 14 connected at a top end 15 thereof to a
rotatable
cylindrical roller 16 in the form of a hollow tube. The sheet 14 depends from
the
tube 16 and vertically downwardly extends therefrom forming from its top end
15 to
its bottom end 17. A weight bar 18 is mounted to the bottom end 17 of the
sheet 14
to weigh it down. The sheet 14 can be of a plurality of suitable materials
usually
Date Recue/Date Received 2021-07-30
7
fabric but other materials can also be contemplated by the skilled artisan and
as
desired by the user.
[0025] The hollow tube 16 houses an actuator assembly 20 for
imparting a
rolling movement to the tube 16.
[0026] The hollow tube 16 defines a pair of opposite longitudinal ends,
namely a "drive" end X' and an idle end X".
[0027] The actuator assembly 20 comprises a clutch 22 defining a
barrel 24
that is inserted within the hollow tube 16 at the drive end X' and a pulley
section 26
containing a pulley gear (as is known in the art) covered by a protective
casing 28.
The pulley section 26 remains external of the tube 16. The pulley section 26
carries
a cord 30 such as a chain. The chain 30 engages the pulley gear, more
specifically,
the pulley gear has teeth and the beads 32 (see also Figure 3) of the chain
are
positioned between the pulley gear teeth. Thus, when the user pulls on either
side
31 or 33 (see also Figure 3) of the chain 30, the pulley gear will rotate in
the direction
of a given chain side 31 or 33, as shown by arrows I and II. Therefore, the
barrel
24 which is connected to the pulley gear and which is snugly fitted within the
tube
16 will impart a corresponding rotation to the tube 16 thereby rolling the
sheet 14
about the tube (in direction I), thus uncovering the window by raising end 17
and
unrolling the sheet 14 from the tube 16 (in direction II) thus covering the
window by
lowering end 17. The clutch 22 may contain various spring tensioners as is
well
known in the art.
[0028] An end barrel plug 34 is snuggly fitted into the hollow tube
16 at the
other end X" thereof.
Date Recue/Date Received 2020-11-20

[0029] The clutch 22 is mounted to a drive end bracket 36A and the
barrel
plug is mounted to a idle end bracket 36B. The brackets 36A and 36B are
mounted
to a surface structure about the window, such as a wall.
[0030] It is understood that the corded window covering 10 shown here
is but
one non-limiting illustrative example of a variety of corded window coverings
within
the scope of the present disclosure. Thus, a variety of cord actuators with
various
pulleys, gears, wheels for reciprocally moving blinds or slats and the like
can be
contemplated within the scope of the present disclosure. Indeed, the present
disclosure is drawn to any window covering using a cord as part of an actuator
assembly for reciprocally covering and uncovering the window as is well known
in
the art.
[0031] As is shown in the present example, the cord 30 extends along
a given
length of the window (or the unrolled blind sheet 14.). In an embodiment, the
cord
extends between about 2/3 of the length of the window to about the full length
of the
window. In an embodiment, the cord 30 is about 48 inches from the floor.
[0032] With respect to Figures 1, 2 and 3, the cord defines a top end
38
connected to the actuator assembly 20, a bottom loop end 40 and a main portion
42
therebetween defining the two sides 31 and 33.
[0033] A protective enclosure 44 provides for covering cord 30 such
that the
bottom loop end 40 is exposed.
[0034] The protective enclosure 44 covers a length of the main
portion 42 of
the cord 30. The main portion 42 includes upper and bottom portions 43 and 45.
The upper portion 43 is contiguous a top portion 49 including the top end 28.
The
bottom portion 45 includes the bottom loop end 40. The protective enclosure
covers
Date Recue/Date Received 2020-11-20
9
the upper portion 43 of the cord 30 and leaves the bottom portion 45 exposed
for
being used to pull the actuator assembly 20.
[0035] With respect to Figures 2, 3 and 4, the protective enclosure
44
comprises a vertically extending longitudinal hollow member with an outer
shell body
46 defining an inner tunnel 47 for receiving the main portion 42 of the cord
30
therethrough. The outer shell body 46 defines top and bottom ends thereof, 48
and
50. The top end 48 defines a top end opening 52 for allowing the top end 38 of
the
cord 30 to engage the actuator assembly 20. The bottom end 50 defines a bottom
end opening 54 for allowing the loop end 40 of the cord 30 to extend
therethrough
so as to be exposed. The bottom portion 45 of the cord including the bottom
loop
end 40 hangs below the bottom end opening 54; it is this portion (bottom
portion 45)
that is manipulated by the user for operating the movement of the cover 14.
[0036] The exposed bottom portion 45 of the cord 30 is too short to
wrap
around a one-year-old child's neck (i.e. not more than about 22 cm in length)
or form
a loop that can be pulled over a one-year-old child's head (i.e. not more than
about
44 cm in circumference) when subjected to the gradual application of force
attaining
35 N. Thus, the depending on the overall length of the cord 30, a suitable
vertical
length of the protective enclosure 44 will be provided in order to expose a
bottom
portion that is not more than about 22 cm in length and/or not more than about
44
cm in circumference.
[0037] In an embodiment, the upper portion 43 has a length that is
greater
than the length of the bottom portion 45. In another embodiment, the upper
portion
43 has a length that is lesser than the length of the bottom portion 45. In
another
embodiment, the upper portion has a length that is the same as the length of
the
bottom portion 45.

4, the
outer shell body 46 comprises a rectangular configuration.
[0039] Turning to Figure 5, there is shown a protective enclosure 144
having
a cylindrical configuration and comprising an outer shell body 146 in the form
of
vertically extending longitudinal hollow cylindrical tube member defining an
inner
tunnel 147 for receiving the main portion 42 of the cord 30 therethrough. The
outer
shell body 146 defines top and bottom ends thereof, 148 and 150. The top end
148
defines a top end opening 152 for allowing the top end 38 of the cord 30 to
engage
the actuator assembly 20. The bottom end 150 defines a bottom end opening 154
for allowing the loop end 40 of the cord 30 to extend therethrough so as to be
exposed.
[0040] It should be noted that various geometric configurations of
the outer
shell body of the protective enclosure can be contemplated within the scope of
the
present disclosure, including rectangular, triangular, cylindrical or tubular
configurations, various trapezoidal configurations, oval configurations and
other
shapes and designs according to purchaser tastes and desires as will be
appreciated by the skilled artisan.
[0041] With respect to Figures 4 and 5, the protective enclosure 44
is
mounted to the wall surrounding the window.
[0042] In an embodiment, the protective enclosure of the disclosure is
