PET STEPS

Abstract

A retractable and collapsible pet stool that is slidable across the floor. In the two step embodiment, which can be increased to three or four steps or more, a first step is provided that is supported on three sides by support members of substantially of equal length to provide a substantially horizontal first step. A second step is provided that is supported on three sides by support members of substantially of equal length to provide a substantially horizontal second step. The support members of the second step are sufficiently shorter than the support members for the first step to permit the second step to selectively slide under and be removed from under the first step. The steps are detachable from each other to permit placement in different areas of the premises.

DETAILED DESCRIPTION OF THE INVENTION

[0063] FIGS. 1 through 15 and FIGS. 20 through 28 are directed to a first embodiment of the pet steps of present invention that is comprised of a three step staircase for easy accessibility of pets, i.e., a retractable step stool for pets that rests on a floor and is slidable across the floor. FIGS. 16 through 19 are directed to a second embodiment of this invention that is comprised of a two-step version similar to the first embodiment, and additionally has provision for a storage space below the top step. FIGS. 29 and 30 are directed to a third embodiment of this invention that is comprised of a four-step version similar to the first embodiment. All these embodiments will be described in greater detail below. It should be noted that in some of the drawings the front panels have been removed for clarity and understanding.

[0064] Referring to the first embodiment shown in FIG. 1, the staircase or retractable step stool for pets is shown generally as 30 and is comprised of main base cabinet and top or first step 40, a middle step or second step 60 and a bottom step or third step 80. In FIGS. 1-3, the staircase 30 is shown in an open expanded position wherein all the steps have been extended to allow for the pet 35 to progress up and down steps 40, 80, and 60. The pet 35 sits perched on top or first step 40. FIG. 4 shows the staircase or pet steps 30 in a closed, collapsed position with steps 60 and 80 pushed inwardly to reside inside of the main base cabinet or top step 40. FIGS. 1 through 4 show the staircase in the open and closed configurations.

[0065] Referring to FIGS. 1-15 and FIGS. 20-28, the pet steps of this invention comprise a main base cabinet and top or first step 40 that has two side panels 42, rear panel 44, front upper panel 46 and top step or top surface 48. Front panel 46 has a handle 47 and top 48 that has a textured surface 49 which can be carpet or any other non-skid means to prevent the pet from slipping on the top surface 48 or to provide a soft surface to lie on.

[0066] Referring for example to FIGS. 2, 5 and 6, the bottom surface 50 is the area of contact with the floor and is the lowermost portion of side panels 42 and rear panel 44. Internal side rails 52 are located on the interior of sidewalls 42 and are designed to interface with related rails 74 of middle step 60 for alignment and support of the middle step 60.

[0067] Referring to FIGS. 11 and 13, middle step 60 includes two side panels 62, rear panel 64, front upper panel 66 and top 68. Referring to FIGS. 3, 4, and 10, front panel 66 has a handle 67 and top 68 has a textured surface 69 which can be carpet or any other non-skid means to prevent pets from slipping. The bottom surface 70 is the area of contact with the floor is the lowermost portion of side panels 62 and rear panel 64 and are adapted to be slidably supported on the floor. Referring to FIGS. 6 and 7, internal side rails 72 are located on the interior of sidewalls 42 and are designed to interface with external rails 94 of lower step 80 for alignment and support purposes. External rails 74 located on the outside of sidewalls 62 interface with internal rails 52 of top step 40 for alignment and support purposes.

[0068] Referring to FIGS. 1 and 11, a stop 76 is provided at the rear edge of 68 in order to prevent the step 60 from disengaging with top step 40 by way of contact with the interior surface of front panel 46. This can be seen in FIG. 1.

[0069] Referring to FIGS. 14 and 15, the third bottom step 80 includes two side panels 82, a rear panel 84, and front upper panel 86 and top 88. As seen in FIGS. 1, 3 and 4, front panel 86 has a handle 87 and top 88 having a textured surface 89 thereon which can be a carpet or any other non-skid means to prevent the pet from slipping. The bottom surface 90 is the area of contact with the floor and is the lowermost portion of side panels 82 and rear panel 84 and are adapted to be slidably supported on the floor. External rails 94 located on the outside of sidewalls 82 interface with internal rails 72 of second middle step 60 for alignment and support purposes. Additionally, a stop 96 is provided at the rear edge of 88 in order to prevent the step 80 from disengaging with middle step 60 by way of contact with the interior surface of front panel 86. This can be seen in FIG. 1.

[0070] In operation the staircase 30 would be positioned adjacent the desired area that the pet owner wishes to allow their pet 35 access to, such as a bed, couch or otherwise and by pulling out the third lower step 80 and then pulling out the second middle step 60 until stops 76 and 96 contact front panels 66 and 86 respectively. This assures full extension of the staircase 30 for a stable environment for pet 35 to traverse safely up and down staircase 30 as needed or desired.

[0071] The support of the pet steps 30 while opened or collapsed does not rely on the side rails 52, 72, 74 and 94 of steps 40, 60 and 80, respectively, to physically support the weight of the pet steps 30 and the pet 35. The pet steps 30 are supported by the closely spaced and aligned bottom surfaces 50, 70 and 90 of steps 40, 60 and 80 to be in contact with the floor surface to support the weight of the pet steps 30 and, for example, a relatively heavy dog 35 as depicted in FIG. 1. Additional means such as nylon glides and or felt and the like could be implemented to assist in smooth operation. Further enhancements such as wheels and so forth could be included to assist in portability and placement of the staircase 30.

[0072] FIGS. 16 through 19 are directed to a two-step staircase or pet step 100 that is comprised of a main base cabinet top step 140 and a bottom step 180. This embodiment is similar in structure to the first embodiment but is a lower height profile and additionally provides for a storage space beneath the top step. It should be noted that in some of the drawings the front panels have been removed for clarity and understanding.

[0073] Still referring to FIGS. 16 through 19, main base cabinet and top step 140 has two side panels 142, rear panel 144, front upper panel 146 and top 148. Front panel 146 has a handle 147 and top panel 148 that can be opened using knob 156 to expose storage area 154 via hinges 158 attached to rear wall 144. The bottom surface 150 is the area of contact with the floor and is the lowermost portion of side panels 142 and rear panel 144 and are adapted to be slidably supported on the floor. Internal side rails 152 are located on the interior of sidewalls 142 and are designed to interface with related external rails 194 of lower step 180 for alignment and support purposes.

[0074] Bottom step 180 includes two side panels 182, rear panel 184, front upper panel 186 and top 188. Front panel 186 has a handle 187 and top 188. The bottom surface 190 is the area of contact with the floor and is the lowermost portion of side panels 182 and rear panel 184. External rails 194 located on the outside of sidewalls 182 interface with rails 152 of top step 140 for alignment and support purposes.

[0075] It is preferred that the external or outside rails 74, and 194 not continue all the way to the rear end of the step, see for example FIG. 13. This permits easy assembly of the steps. For example, external rails 74 and 194 are inch shorter than of the full length of the step. This allows a 3 step staircase to become a 2 step, and a 4 step to become a 3 step if desired. With this design, keeping the cut out at the end of the external or outside rail permits each step to be similar to the other steps permitting the creation of similar plastic molds that can be assembled after each step is created.

[0076] Also, our stairs are designed to have a little movement in each step. By that I mean, the steps do not fit into each other tightly. There must be a little wiggle room. The reason for this is because dogs obviously won't use the staircase the same way properly all the time. They get excited, they jump, they run; for this reason, and since this may be an all wood product, to keep the rails themselves from coming loose or breaking off we allow the steps to be able to move slightly from side to side (right to left) to accommodate the inconsistent use from pets.

[0077] A primary feature of the invention is the increased step tread dimension for a four legged pet. As can be seen in the drawings the depth of each step is much deeper than a conventional step for both human use and other steps designed for pets. The rise is the vertical dimension between the floor or each landing or step. The tread is the horizontal dimension from the front of the step to the next rise. All current pet staircases follow the standard rise and tread of a 711 step which are engineered for human use. They are too small for four legged pets and especially pets with health and geriatric issues. The staircase, retractable step stool or pet steps of the present invention have a rise of 6 with a minimum 16 tread, and as long as 24 so a pet can stand on each step. This creates a more comfortable ascent and a more safe descent down the stairs. It is easier on their joints because it keeps the dog in a less angled position going up or down the stairs. The proportions of the current invention can be scaled to accommodate animals and pets of many sizes from small to large simply by adjusting the dimensions of the related rise and tread of each step in order to provide sure footing.
