Description CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority under 35 U.S.C. .sctn.
119(e) to U.S. Provisional Patent Application No. 60/370875 filed
Apr. 7 2002 the entire disclosure of which is incorporated herein
by reference.
FILED OF THE INVENTION
[0002] The present invention is directed to a cat litter box and
more particularly to a cat litter box that is well-suited for placement
in a corner of a room.
BACKGROUND OF THE INVENTION
[0003] Cat litter boxes typically include a rectangular floor and
four upwardly extending sidewalls. Some cat litter boxes also include
a cover or lid for deflecting cat litter displaced above the sidewalls.
However, some cats refuse to use covered litter boxes. Additionally,
lids typically fail to deflect all cat litter, resulting in cat
litter landing outside of the box and scattering on the floor adjacent
the box.
[0004] Normal use of cat litter boxes involves the deposition of
cat litter into the box. The cat or cats use the box for a given
amount of time. Then, the cat litter is removed from the box, typically
by lifting the box, turning it, and then pouring the litter out
of the box, over the edge of one or more of the side walls. Some
cat litter often spills onto the floor during this process, leading
to more work for the cat owner.
[0005] Most cat litter boxes have a flat bottom that rests directly
on the floor or is positioned close to the floor. This characteristic
can lead to further problems. Additionally, as cats age or become
infirm, it can become difficult for them to enter and exit a cat
litter box. This can lead to cats not wanting to use a cat litter
box. Instead, they use a more convenient location, such as a floor,
leading to damage of flooring, odors, and other undesirable effects.
Some "finicky" cats also simply refuse to use a cat litter
box, particularly when urinating. They instead urinate just outside
the litter box. Urine then runs under the box and soaks the bottom
of the box where it is difficult and inconvenient to clean the box
and floor. For example, the box must be lifted and then its underside
must be cleaned while the box is elevated. In addition, because
air cannot get between the flat bottom periphery of the box and
the floor, the box the floor may remain damp for a long time, leading
to floor damage and bacteria growth.
[0006] FIGS. 1-3 show a prior art corner cat litter box 10 having
the limitations described above. Box 10 is configured for placement
in a corner and, therefore, is generally triangular in shape. Litter
box 10 includes a bottom portion 12 and a cover 14 mountable on
the bottom portion 12. Cover 14 includes two sidewalls 16 and 18
and a front wall 20 that spans from one sidewall 16 to the other
sidewall 18. The bottom portion 12 includes two sidewalls 22 and
24 and a front wall 26 that spans from one sidewall 22 to the other
sidewall 24. The front walls 20 and 26 have cutouts that meet to
form an entranceway 28 through which a cat can enter and exit. In
one implementation of the cat litter box 10 shown in these figures,
a door (not shown) is hingedly attached to an upper edge 30 of the
entranceway 28 virtually completely enclosing the cat litter box
10. While cat owners might find this feature desirable, most cats
do not like to have their view blocked when they are in such a vulnerable
position. Because the cat litter box 10 lacks a true handle, the
box 10 is not easily lifted. Furthermore, the bottom 12 of the box
10 must be balanced while the box 10 is elevated, or it must be
turned over as the underside 32 is cleaned. Balancing the box 10
is difficult because it lacks a pivot point.
[0007] FIG. 2 shows an underside 32 of the floor 19 of the prior
art corner cat litter box 10. The underside 32 includes a raised,
outer edge 34 which contacts a room's floor 36 on which the cat
litter box 10 is positioned, and an inner area 38 which is elevated
off of the floor 19. This underside 32 configuration of the prior
art box 10 has several drawbacks. First, the strength of the underside
32 is relatively low. When the cat litter box 10 is filled with
cat litter and a large 12 to 20 pound cat enters the box 10 the
inner area 38 will bend, thereby stressing and weakening the underside
32 of the cat litter box 10. Second, where a cat urinates outside
of and next to the cat litter box 10 urine can seep under the box
10 and can travel along the outer edge 34 to coat a relatively large
surface of the underside 32 with urine. This makes cleaning the
underside 32 of the cat litter box 10 difficult and inconvenient.
The underside of the box and floor are also slow to dry due to poor
circulation between the box and the floor. The box 10 must be lifted
to clean the underside 32. Additionally, the floor 19 must be cleaned
while the box 10 is elevated and/or balanced.
[0008] Therefore, what is needed is an improved cat litter box
that does not require a lid or a cover, but that still leads to
the deflection of cat litter.
[0009] What is also needed is an improved cat litter box that facilitates
pouring cat litter out of the box when it is desired to remove cat
litter from the box.
[0010] It would additionally be desirable to provide a cat litter
box that is easily entered and exited.
[0011] What is also needed is a cat litter box that avoids the
need to clean its underside if a cat urinates next to the box.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF AT LEAST ONE PREFERRED EMBODIMENT
[0042] FIGS. 4-7 illustrate a corner cat litter box 40 that is
made in accordance with a preferred embodiment of the invention
and that is disposed in a corner 42 of a room. A pair of sidewalls
44 46 extend upwardly from a floor 48 and are disposed generally
perpendicularly to each other. A front wall 50 extends outwardly
from the floor 48. The front wall 50 extends arcuately from one
sidewall 44 to the other sidewall 46 and has a cut-out portion forming
an entranceway 52 through which a cat (not shown) can enter and
exit.
[0043] Referring additionally to FIGS. 8-11 an underside 56 of
the floor 48 has a plurality of discrete legs 54 that support the
underside 56 of the floor 48 from the floor of the room in a spaced-apart
fashion. In a preferred embodiment, each leg 54 is integrally formed
as part of the floor 48. Each leg 54 comprises a rounded or hemispherical
protrusion that is integrally molded into the underside 56 of the
floor 48. There is a leg 54 located adjacent each front corner of
the floor 48 a leg 54 located in line with and below the entranceway
52 a leg 54 located adjacent the rear corner of the floor 48 and
a pair of legs 54 located between the leg 54 adjacent the rear corner
of the floor 48 and the legs 54 located adjacent the front corners
of the floor 48. Such an arrangement is beneficial as it helps ensure
that all of the underside 56 of the floor 48 is spaced from the
floor of the room even when the box 40 is relatively full of cat
litter and has a cat (not shown) in the box. Additionally, the arrangement
of legs 54 shown in FIGS. 8-11 provides uniform support for the
floor 48 of the box 40 helping to ensure that the underside 56
of the floor 48 of the box 40 is always spaced from the floor. The
legs 54 preferably are sufficiently long to space the underside
56 of the floor 48 at least {fraction (1/16)} of an inch from the
floor. Legs sufficiently long to form spacings or gaps of {fraction
(1/16)}", 1/8", {fraction (3/16)}", or even larger
are feasible.
[0044] Each sidewall 44 46 is substantially straight and generally
parallel to one of the walls of the room when the box 40 is disposed
in a corner of the room. To help retain cat litter in the box 40
while permitting the front part of the box 40 to be raised, each
sidewall 44 46 preferably extends above the intended litter line
by at least about 11/2" and more preferably at least about
21/2". In the preferred embodiment shown in the drawing figures,
each sidewall 44 46 has a lip 58 that extends outwardly such that
it helps ensure that a gap between each sidewall 44 46 and an adjacent
room wall. Each lip 58 is outturned and downturned such that it
curls generally downwardly. Each lip 58 also extends along the entire
length of the top edge of both sidewalls 44 46. This lip, in combination
with the legs 54 that space the underside 56 of the floor 48 from
the floor of the room, helps ensure good ventilation around and
underneath the cat litter box 40. The outturned lip 58 helps seal
the box 40 against a wall of the room to help return back into the
box 40 litter kicked up by a cat in the box 40. As a result, no
cover or lid is necessary. Any spills around the cat litter box
dry quickly. Preferably, a lip 60 also extends about the top edge
of the front wall 50.
[0045] The front wall 50 of the cat litter box 40 is curved such
that it bows slightly outwardly away from the corner of the room.
More specifically, with regard to the preferred embodiment shown
in the drawing figures, the front wall 50 extends generally perpendicularly
upwardly such that it is within about 15 degrees of being perpendicular
to the floor 48.
[0046] Referring back to FIGS. 4 and 5 and referring additionally
to FIGS. 12-17 the entranceway 52 includes a platform 62 that extends
outwardly from the front wall 50 away from the interior of the cat
litter box 40. The platform 62 is configured to serve as an ingress
and egress platform 62. To this end, it is angled relative to the
front wall 50 so as to facilitate entry and exit of a cat (not shown)
to and from the cat litter box 40. Referring to FIG. 14 the platform
62 forms an obtuse angle, .alpha., with the front wall 50. In one
preferred embodiment, the ingress and egress platform 62 is obtusely
angled relative to the front wall 50 at an angle, .alpha., of between
e.g., about 110 degrees and about 165 degrees, and most preferably
of about 135 degrees.
[0047] The ingress and egress platform 62 includes a landing surface
64 that is disposed above the intended litter line in the cat litter
box 40 and below the top edge of the front wall 50. In the preferred
embodiment shown in the drawing figures, the landing is the top
surface of the platform that faces toward a cat entering or leaving
the box 40. Preferably, the landing 64 is oriented at the same angle
as the platform 62. Even more preferably, the landing 64 is oriented
at an angle common with the platform 62. Hence, the landing is disposed
at an angle of between about 110 degrees and about 165 degrees relative
to the front wall 50 and more preferably of about 135 degrees.
This orientation helps give a cat (not shown) entering the box 40
leverage to help pull themselves into the box 40 using their front
paws. This is particularly advantageous for cats that are elderly
or infirm, thereby making it easier for them to enter the box 40.
In a preferred embodiment, the highest point of the landing 64 is
no higher than about 3" to about 5", and more preferably
about 5", off the floor to facilitate ingress and egress. The
landing 64 also is preferably curved so as to facilitate redirection
of the thrust or momentum of a cat attempting to enter the litter
box 40 towards the center of the litter box 40. To facilitate ingress
and egress of a cat, the bottom edge of the platform 62 is spaced
no more than about three inches above the floor 48 of the box 40.
Preferably, the top or outer edge of the platform 62 is spaced at
least one inch below the top edge of the front wall 50. In addition,
the entranceway 52 is also sufficiently wide relative to the length
of the front wall 50 to provide a cat with sufficient freedom of
vision to prevent it from feeling enclosed or "boxed in"
when it is inside the litter box 40. The entranceway 52 preferably
has a width that extends about 1/5.sup.th to about 1/3.sup.rd the
length of the front wall 50. In a box in which the front wall 50
is between about 24" and about 30" long, the entranceway
52 should have an average width (as measured along the height of
the entranceway) of between about 6" and about 12", more
preferably of between about 8" and about 10", and most
preferably of about 9". Such an arrangement with a low and
wide entry makes the entranceway 52 particularly well-suited for
aged or infirm cats who have difficulty getting into litter boxes
having higher sidewalls. Additionally, it allows the cat to feel
secure as it can see outside the box while the box can maintain
the previously noted advantages of having high sides.
[0048] The platform 62 may include a pair of side panels 66 68
that extend along one edge of the landing 64 to the front wall 50.
The side panels 66 68 help redirect the thrust or momentum of a
cat attempting to enter the box 40 at an angle should the cat attempt
to enter the box 40 off center toward one edge of the landing 64.
If the platform 62 is equipped with side panels 66 68 each side
panel preferably is obtusely angled relative to the front wall 50.
Referring to FIG. 16 in one preferred embodiment, each side panel
66 68 forms an included angle, .beta., with the exterior surface
of the front wall 50. The angle, .beta., preferably is between about
100 degrees and about 155 degrees, and more preferably is about
135 degrees.
[0049] Collectively, the landing 64 and the side panels 66 68
not only define the ingress and egress platform 62 but they also
function as a spout or funnel that helps return cat litter back
into the box 40 kicked up by a cat entering or leaving the box.
This same spout or funnel arrangement also advantageously facilitates
the pouring cat litter from the box 40 when it is desired to remove
cat litter from the box 40.
[0050] In the preferred embodiment of the cat litter box 40 shown
in the drawing figures, the outer edge of the landing 52 has an
outturned lip 70 that also functions as a handle. For example, should
liquid somehow get onto the floor underneath the cat litter box
40 the handle 70 can be grasped to raise the front portion of the
box 40 off of the ground to permit the liquid to be wiped up. This
is particularly useful where a cat urinates next to the litter box
40 and urine seeps under the cat litter box 40.
[0051] When the inventive box 40 is lifted, the lip 58 along each
sidewall 44 46 rides along one of the walls of the room to support
the box 40. This maintains the location of the box 40 in the corner
when the box 40 is lowered. In addition, the leg 54 serves as a
pivot about which the box 40 rotates when the box 40 is lifted.
Maintaining point contact between the leg 54 and the floor helps
permit the leg 54 to slide on the floor as the box is lifted. It
also helps facilitate pivoting of the rear corner of the box 40.
This can be done easily and conveniently without spilling cat litter
from the box 40 onto the floor. Thereafter, the front end of the
box 40 can be lowered to return it to its original location in the
corner of the room. This arrangement also helps to easily move the
front end of the box 40 away from the corner of the room, such as
when it is desired to empty or clean the box 40.
[0052] When it is desired to remove litter in the box 40 the box
40 is pulled away from the corner and lifted. The box 40 is grasped
by its sidewalls 44 46 and tilted such that the front wall 50 is
lowered toward the floor of the room. As the front wall 50 is lowered,
cat litter will start to move toward the entranceway 52. The curvature
of the platform 62 helps channel or direct the litter into another
container, such as a garbage can or a garbage bag. The side panels
66 68 also help direct litter toward the platform 62 where it
easily flows out of box 40.
[0053] In a preferred embodiment, the box 40 is of molded, one-piece
unitary construction. Preferably, the box 40 is molded of a plastic.
[0054] It is understood that one or more preferred embodiments
are shown and described above to illustrate different possible features
of the invention and the varying ways in which these features may
be combined. Apart from combining the different features of any
of these embodiments in varying ways, other modifications are also
considered to be within the scope of the invention.
[0055] It is also to be understood that, although the foregoing
description and drawings describe and illustrate in detail one or
more preferred embodiments of the present invention, to those skilled
in the art to which the present invention relates, the present disclosure
will suggest many modifications and constructions as well as widely
differing embodiments and applications without thereby departing
from the spirit and scope of the invention. The present invention,
therefore, is intended to be limited only by the scope of the appended
claims. |
