DETAILED DESCRIPTION OF THE INVENTION
(17) The embodiments of the present invention are illustrated in FIGS. 1-16. FIGS. 1 and 2 show one embodiment of pet mobility carrier assembly 10. FIG. 1 is a front, left perspective view and FIG. 2 is a rear right perspective view. Pet mobility carrier assembly 10 includes a carrier base 30, a carrier animal support 60 and at least three rollers 90 (rollers are shown in FIG. 8). Carrier animal support 60 is connected to carrier base 30 and provides a surface upon which disabled rear legs of a disabled animal is positioned. The at least three rollers 90 are connected to the bottom of carrier base 30 and allows pet mobility carrier assembly 10 to move across a surface such as, for example, a floor. On a base perimeter surface 36, there is disposed a plurality of releasable attachment points 180 used to secure a disabled animal to pet mobility carrier assembly 10.
(18) In this embodiment of carrier animal support 60, carrier animal support 60 has a raised berm 70 around a portion of a periphery of carrier animal support 60, which defines a space 72 within a central portion 61 of carrier animal support 60 for receiving the disabled rear legs of the disabled animal. It is understood that raised berm 70 is not necessary to the functioning of carrier animal support 60 and a flat, planar surface would also suffice. On a front end 31 of carrier base 30 is a base recess portion 40 that typically has a radius R1 and an arc distance or chord length to accommodate the non-disabled front legs or the non-disabled rear legs of the disabled animal when the disabled animal walks thereby moving pet mobility carrier assembly 10.
(19) FIG. 3 is a top view of pet mobility carrier assembly 10. As can be seen in this embodiment, the peripheral shape of carrier base 30 has an arcuate, convex shape and base recess portion 40 has an arcuate, concave shape. As is evident in this embodiment, carrier animal support 60 has a similar shape as carrier base 30. The similarity of the shapes is not important or critical to the present invention. For example, the sides as indicated by the area S may be parallel to each other along a major portion of the periphery between front end 31 and back end 32. Furthermore, back end 32 may be arcuate, multi-sided or perpendicular to sides S.
(20) FIG. 4 is a bottom view of pet mobility carrier assembly 10. In this embodiment, there are 4 rollers connected to base carrier 30. The features appearing to connect between rollers 90 are simply features caused by the molds for injection molding and are not critical features of base carrier 30. In fact, a flat, planar surface could be used to which rollers 90 are attached. In both views of FIGS. 3 and 4, it is shown that four releasable attachment points 180 are incorporated. The attachment points 180 are typically positioned along the base perimeter portion 38 in locations that are best suited for attaching a disabled animal to pet mobility carrier assembly 10. In this embodiment, carrier base 30 has a length L1 in a range of about thirteen inches to about twenty inches (about 33 cm to about 51 cm) and a width W1 in a range of about twelve inches to about twenty inches (about 30.5 cm to about 51 cm). It is understood that these thickness dimensions are not limiting but may be varied depending on the size and weight of the disabled animal. Base recess portion 40 of carrier base 30 has a radius R1 in a range of about two and a half inches to about four inches (about 6.4 cm to about 10.2 cm), and preferably in a range of about three inches to about four inches (about 7.6 cm to about 10.2 cm). It is understood that these radial dimensions for the base recess portion 40 are not limiting but may be varied depending on the size and weight of the disabled animal, the length of the stride and the distance between the non-disabled legs of the disabled animal.
(21) FIGS. 5, 6 and 7 are a front view, a rear view and a cross-sectional view of pet mobility carrier assembly 10, respectively. In the front view of FIG. 5, it is shown that raised berm 70 does not completely surround central portion 61 but delineates an open portion 62 that communicates with space 72 bounded by raised berm 70 from which the main body of the disabled animal extends toward the disabled animal's non-disabled front legs. Raised berm 70 helps retain the disabled rear legs or hind quarters on the pet mobility carrier assembly 10 as the disabled animal moves along a floor. It is understood that the use of pet mobility carrier assembly 10 with its plurality of rollers 90 compared to a drag bag alone greatly reduces friction against a floor allowing the disabled animal greater mobility with much less effort on the part of the disabled animal. The pair of front releasable attachment points 180 are shown to which a restraining assembly is removably secured to front end 31 of carrier base 30. As shown in FIG. 5 and FIG. 4, the rollers 90 at front end 31 are spaced wider apart than rollers 90 at back end 31. This arrangement provides greater stability to pet mobility carrier assembly 10 when connected to a disabled animal where a greater portion of the animal's non-disabled body extends from carrier assembly 10 while providing carrier base 31 with a more streamlined cross-section for movement along a planar surface such as a floor where there is likely other obstacles on the floor that could create impediments to the animal's mobility.
(22) From back end view of FIG. 6, the pair of rear releasable attachment points 180 are shown to which a restraining assembly is removably secured to back end 31 of carrier base 30.
(23) Turning now to FIG. 7, the cross-sectional view taken along line 7-7 in FIG. 1 shows the cross-sectional shape of carrier animal support 60 as well as cross-sectional view of carrier base 30 that is one design for an injection molded piece. Even more notable is the low form profile of pet mobility carrier assembly 10. As shown in FIG. 7, the height H1 in this embodiment between a surface upon which rollers 90 rest and a base bottom 34 of carrier base 30 (also called the clearance height) is about one inch (about 2.54 cm). The thickness H2 of carrier base 30 between carrier base bottom 34 and a carrier base top 33 is also about one inch (about 2.54 cm). The thickness H3 of carrier animal support 60 between a carrier support bottom 64 and a carrier support top 63 is about 1.75 inches (about 4.4-4.5 cm). Thickness H3 includes raised berm 70. The thickness H4 of central portion 61 of carrier animal support 60 is about three-quarters of an inch (about 1.9 cm). It is understood that these thickness dimensions are not limiting but may be varied depending on the size and weight of the disabled animal.
(24) Turning now to FIG. 8, there is illustrated an exploded view of pet mobility carrier assembly 10 of FIG. 1. Carrier base 30 may be made of any rigid material such as, for example, metal or plastic or composite materials or combinations thereof but an injection molded plastic is the more economical choice for large quantities and customer pricing. Base top 33 may be completely planar or have planar portions for supporting carrier animal support 60. In the embodiment illustrated, the channels shown are a result of the mold used for injection molding carrier base 30 and the roller recesses are provided for attachment structure to retain rollers 90 to carrier base 30 while not interfering with carrier animal support 60 when carrier animal support 60 is connected to carrier base 30. Carrier animal support 60 may be made of a cushioning material such as, for example, a foam pad or a foam pad fixedly attached to a rigid support base 60i as shown in FIG. 8B. Carrier animal support 60 may be fixedly attached to base top surface 33 or may be removably connected to base top surface 33. For easier cleaning or replacement of carrier animal support 60, a releasable fastener assembly 60h is connected between carrier base 30 and carrier animal support 60. A usable releasable fastener assembly 60h includes, but is not limited to, a hook and loop fastener, a snap, a quick-release fastener, a reusable double-sided tape, and the like. The at least three rollers 180 may be any known multi-directional rollers such as, for example, pivoting wheels, omni-directional wheels/rollers, and the like. Rollers 180 are secured to base bottom 34 but may be removable for replacement or cleaning. Releasable attachment points 180 are fixed to base perimeter surface 36 of carrier base 30. Releasable attachment points 180 may be any known releasable fasteners such as, for example, snaps, buttons, buckles, clips and O-rings, hook and loop fastener, twist-lock fasteners, etc.
(25) FIG. 9 is a perspective view of a disabled animal 1 connected to pet mobility carrier assembly 10. In this illustration, animal 1 has disabled rear legs, which are placed within a drag bag 120 and secured to animal 1 using a chest strap 122 of drag bag 120 where chest strap 122 connects to itself around the animal's neck. As illustrated, drag bag 120 includes adjustment bag strap 124 with eyelet 125 that is connected to releasable attachment point 180, which is a twist lock fastener, at front end 31 of carrier base 30. Drag bag 120 has an eyelet 125 attached to a corner 126 where eyelet 125 is connected to releasable attachment point 180, which is also a twist lock fastener, at back end 32 of carrier base 30.
(26) Turning now to FIGS. 10-16, there is illustrated another embodiment of pet mobility carrier assembly 10 for use with an animal having front disabled legs. FIGS. 10 and 11 illustrate front and rear perspective views of pet mobility carrier assembly 10. In this embodiment, carrier base 30, rollers 90 and releasable attachment points 180 are the same as those previously discussed and so will have identical reference numbers as previously disclosed. The main difference is the structure of carrier animal support 60. The difference lies in the height dimensions of carrier animal support 60 to accommodate the front disabled legs and chest of the disabled animal while preserving as close as possible the disabled animal's standing position prior to the animal becoming disabled. Further, as shown in FIG. 16, the disabled animal's non-disabled rear legs are positioned at the back end 34 of carrier base 30.
(27) Pet mobility carrier assembly 10 includes carrier base 30, a carrier animal support 60 and at least three rollers 90 (rollers are shown in FIG. 8). Carrier animal support 60 is connected to carrier base 30 and provides a surface upon which disabled front legs and chest of a disabled animal is positioned. The at least three rollers 90 are connected to the bottom of carrier base 30 and allows pet mobility carrier assembly 10 to move across a surface such as, for example, a floor. On a base perimeter surface 36, there is disposed the plurality of releasable attachment points 180 used to secure the disabled animal to pet mobility carrier assembly 10.
(28) In this embodiment of carrier animal support 60, carrier animal support 60 has a raised side berm 70 along each side portion 60a of the periphery of carrier animal support 60, which defines a space 72 within a central portion 61 of carrier animal support 60 for receiving the disabled front legs and chest of the disabled animal. It is understood that raised berm 70 is not necessary to the functioning of carrier animal support 60 and a flat, planar surface would also suffice. On front end 31 of carrier base 30 is base recess portion 40 that typically has a radius to accommodate the non-disabled rear legs of the disabled animal when the disabled animal walks moving pet mobility carrier assembly 10.
(29) FIG. 12 is a top view of pet mobility carrier assembly 10. As can be seen in this embodiment, the peripheral shape of carrier base 30 has a semi-circular back end 32, parallel sides 30a, and base recess portion 40 having an arcuate, concave shape. As is evident in this embodiment, carrier animal support 60 has a similar shape as carrier base 30. The similarity of the shapes is not important or critical to the present invention. For example, the sides 30a may be parallel to each other along a major portion of the periphery between front end 31 and back end 32 or they may diverge away from each other from back end 32 towards front end 31. Furthermore, back end 32 may be arcuate, multi-sided or perpendicular to sides 30a.
(30) FIGS. 13, 14 and 15 are a front view, a rear view and a cross-sectional view of pet mobility carrier assembly 10, respectively. In the front view of FIG. 13, it is shown that raised side berm 70 does not completely surround central portion 61 but delineates an open front portion 62a and an open rear portion 62b that communicates with space 72 between raised side berm 70 which supports the disabled front legs and chest of the disabled animal. Raised side berm 70 helps retain the disabled front legs and chest portion of the disabled animal on the pet mobility carrier assembly 10 as the disabled animal moves along and turns around on a floor. It is understood that the use of pet mobility carrier assembly 10 with its plurality of rollers 90 allows the disabled animal with disabled front legs to move in a generally upright position along a floor allowing the disabled animal greater mobility with much less effort on the part of the disabled animal. The pair of front releasable attachment points 180 are shown to which a restraining assembly is removably secured to front end 31 of carrier base 30. An animal body harness (shown in FIG. 16) is typically used to secure the disabled front legs and/or chest (especially in the case that both front legs have been amputated) to the pet mobility carrier assembly 10. As shown in FIGS. 13, 14 and 4, the rollers 90 at front end 31 are spaced wider apart than rollers 90 at back end 31. This arrangement provides greater stability to pet mobility carrier assembly 10 when connected to a disabled animal where a greater portion of the animal's non-disabled body extends from carrier assembly 10.
(31) Turning now to FIG. 15, the cross-sectional view taken along line 15-15 in FIG. 10 shows the cross-sectional shape of carrier animal support 60 as well as cross-sectional view of carrier base 30 that is one design for an injection molded piece. Even more notable is the low form profile of pet mobility carrier assembly 10. Similar to what is shown in FIG. 7, the heights H1 and H2 in this embodiment between a surface upon which rollers 90 rest and a base bottom 34 of carrier base 30 (also called the clearance height) is the same as that in FIG. 7. The thickness H3 of carrier animal support 60 between a carrier support bottom 64 and a carrier support top 63 is about six inches (about 15.25 cm). The height H4 between a high point of central portion 61 and the highest point of raised side berm 70 is about three inches (about 7.6 cm). The thickness H5 of central portion 61 of carrier animal support 60 from support bottom 64 and the high point of central portion 61 is about three inches (about 7.6 cm). It is understood that these heights and thickness dimensions are not limiting but may be varied depending on the size, leg length (i.e. height) and weight of the disabled animal.
(32) FIG. 16 is a perspective view of a disabled animal connected to pet mobility carrier assembly 10. In this illustration, animal 1 has disabled front legs. An animal chest harness 150 is used to secure the disabled animal 1 to the pet mobility carrier assembly 10. As illustrated, animal chest harness 150 includes an adjustable neck strap 152, an adjustable body strap 154, an adjustable back strap 156 connected between adjustable neck strap 152 and adjustable body strap 154. Straps 152, 154 and 156 are adjustable to fit the size and shape of the disabled animal. Also connected to adjustable neck strap 152 are a pair of carrier straps 158 that are adjustable and extend from adjustable neck strap 152 to releasable attachment points 180 at back end 32 of carrier base 30. Carrier strap 158 has, in this embodiment, an eyelet 125 at a carrier strap distal end 159 that is connected to releasable attachment point 180, which is a twist lock fastener as previously disclosed, at back end 32 of carrier base 30.
(33) Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative. Further modification of the invention herein disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
