STACKABLE PET SHELTER

Description

Summary of Invention

[0012] The preferred embodiments of the stackable pet shelter have several features, no single one of which is solely responsible for their desirable attributes. Without limiting the scope of this invention as expressed by the claims that follow, its more prominent features will now be discussed briefly. After considering this discussion, and particularly after reading the section entitled "Detailed Description of the Preferred Embodiments," one will understand how the features of the preferred embodiments provide advantages, which include ready stackability in an efficient and stable manner.

[0013] Preferred embodiments of the stackable pet shelter comprise a bottom section and a top section that mate to form a sturdy shelter. The bottom section is shaped substantially as a hollow rectangular box having a floor and four sidewalls. The sidewalls slope outwardly, and a first sidewall includes a substantially U-shaped opening. The legs of the U are bent slightly outward. The top section is shaped substantially as a hollow six-walled structure having two opposite rectangular walls, two opposite pentagonal walls and a peaked roof. The sidewalls slope outwardly away from the roof, and a first sidewall includes a substantially U-shaped opening, with the legs of the U bent slightly outward.

[0014] The top and bottom sections are configured such that an inverted top section fits snugly within an interior of a bottom section, and a bottom section fits snugly within an interior of an inverted top section. Thus, preferred embodiments of the pet shelter enable efficient stacking of multiple shelters in a bottom-top-bottom-top-bottom-etc. arrangement. Several features of the pet shelter contribute to its stackability. First, the sidewalls of the top and bottom sections slope at roughly equal angles. Second, the legs of the U-shaped openings are bent at roughly equal angles on both the top and bottom sections. Third, the height of the top section is roughly equal to the height of the bottom section. Fourth, the roof of the top section has a very gradual slope, such that the peak of the roof does not obstruct nesting of a top section within a bottom section.

Detailed Description

[0021] As Fig. 1 illustrates, a preferred embodiment of the stackable pet shelter 10 includes a hollow, substantially rectangular box with a substantially rectangular opening 12 in a front wall 14. One of skill in the art will appreciate, however, that the shelter 10 may include any number of sides or curved surfaces. The shelter 10 may, for example, be substantially triangular in plan aspect, hexagonal, octagonal or even round.

[0022] The shelter 10 is preferably constructed of a high-impact plastic, or another material that is lightweight and durable such as wood or fiberglass. The shelter 10 is constructed of two sections, a top section 16 and a bottom section 18. Both the top and bottom sections are shaped substantially as rectangular boxes with one missing side, and a substantially U-shaped opening in a side adjacent to the missing side. Fig. 3 illustrates the bottom section 18 in isolation.

[0023] The top and bottom sections of the shelter may be secured to one another with tab and slot connectors. Generally horizontally extending tabs 20 (Figs. 3, 4b and 5b) on a back upper edge 21 of the bottom section 18 mate with generally horizontally oriented slots (not shown) on a back lower edge 23 (Fig. 5b) of the top section 16. Generally vertically extending tabs 25 (Fig. 5a) on a front lower edge 27 of the top section 16 mate with generally vertically oriented slots 29 (Fig. 3) on a front upper edge 31 of the bottom section 18. In profile, the tabs 25 resemble an arrowhead that has been bisected lengthwise. Thus, a narrow leading portion of each tab 25 is able to penetrate a slot 29. Once the tab 25 advances through the slot 29 past a shoulder portion, the tab 25 snaps into place and can only be removed from the slot 29 by deforming the slot 29.

[0024] To assemble the shelter 10, the top and bottom sections are oriented such that their missing sides face each other and the open ends of both U-shaped openings are aligned. With the bottom section 18 resting on a flat horizontal surface, the back lower edge 23 of the top section is brought into contact with the back upper edge 21 of the bottom section 18 such that the tabs 20 extend through the slots on the top section. Next, the front lower edge 27 of the top section 16 is brought into contact with the front upper edge 31 of the bottom section 18, such that the tabs 25 snap into and extend through the slots 29.

[0025] One of skill in the art will appreciate that the illustrated manner of attaching the top section 18 to the bottom section 16 is merely exemplary. Many other methods of attachment are equally suitable, including providing horizontally extending lip members on both sections that receive vertically extending pins or bolt and nut fasteners, or providing a vertically extending and overlapping lip on the top portion that receives horizontally extending pins or bolt and nut fasteners. Alternatively, an interference fit or any other attachment mechanisms known to those of skill in the art may be used.

[0026] The side of the bottom section 18 opposite its missing side defines a shelter floor 22, while the side of the top section 16 opposite its missing side defines a shelter roof 24. The remaining sides of the two sections define shelter walls. The shelter floor 22 may include grooves (not shown) for channeling water away from a pet.

[0027] Two shelter 10 walls are preferably longer than the two remaining walls. The long walls define sidewalls 26, while the shorter walls define a front wall 14 and a back wall 28 of the shelter 10. The front wall 14 preferably includes a substantially rectangular opening 12 formed by the adjoining U-shaped openings of the top and bottom sections. The rectangular opening 12 defines a shelter entrance. One of skill in the art will appreciate that the shelter entrance may be any shape, such as triangular, hexagonal, octagonal, or even round. One of skill in the art will also appreciate that the shelter entrance may be formed in any of the shelter sidewalls.

[0028] As best seen in Figs. 2a and 2b, each of the shelter walls slopes gradually from vertical. For the top section 16, the walls slope inward from the missing side to the shelter roof 24. For the bottom section 18, the walls slope outward from the shelter floor 22 to the missing side. Thus, the shelter 10 is preferably widest at a point roughly equidistant from the shelter roof 24 and floor 22.

[0029] Legs 30 of each U-shaped opening are preferably bent outward, such that the legs 30 roughly parallel the shelter 10 walls, as best seen in Fig. 2a. Thus, the widest portion of the shelter entrance is at the junction of the top and bottom sections. As illustrated in Fig. 2b, a narrow lip 32 preferably extends outward from the shelter entrance. The lip 32 prevents water, such as rainwater, from entering the shelter 10. One of skill in the art will appreciate, however, that the lip 32 is not a necessary component of the shelter 10.

[0030] The shelter floor 22 is preferably crowned slightly so that moisture runs away from a pet in the shelter. Alternatively, the floor 22 can be flat or slightly sloped. The shelter roof 24 is preferably slightly peaked, such that a ridge 34 stretches along the center of the roof 24 from the front wall 14 to the back wall 28. The roof 24 thus slopes downward from the ridge 34 toward either sidewall 26. The slope preferably is steep enough to allow the shelter roof 24 to shed rainwater and to discourage pets from climbing on top of the shelter 10. However, the slope is preferably gradual enough to facilitate stacking and nesting of the shelter tops and bottoms, as explained below.

[0031] When the top section 16 is removed from the bottom section 18 and inverted, the top section 16 fits snugly within the interior of the bottom section 18, and the bottom section 18 fits snugly within the interior of the top section 16. Figs. 5a and 5b illustrate a bottom-top-bottom-top stacking arrangement. Figs. 4a and 4b illustrate the internal configuration of the various shelter walls in the stacked arrangement of Figs 5a and 5b.

[0032] As shown in Fig. 4a, the sidewalls 36 of each top section 16 rest against the sidewalls 38 of each bottom section 18, and vice versa. As shown in Fig. 4b, the front walls 40 of each top section 16 rest against the front walls 42 of each bottom section 18, and vice versa, and the rear walls 44 of each top section 16 rest against the rear walls 46 of each bottom section 18, and vice versa.

[0033] Also as shown in both Figs. 4a and 4b, the ridge 34 of the top section 16 rests on the floor 22 of the bottom section 18. Further, as Fig. 4a illustrates, there is very little empty or wasted space between the top sections 16 and bottom sections 18.

[0034] The snug fit between the inverted top sections 16 and bottom sections 18 results from a combination of features of the two sections. One of skill in the art will appreciate, however, that not all of these features are required for snug nesting. The scope of the shelter 10 is not limited to a shelter having all of these features.

[0035] First, the front wall 14, back wall 28 and sidewalls 26 of the top section 16 slope at angles that are roughly equal to the slope of the front wall 14, back wall 28 and sidewalls 26, respectively, of the bottom section 18. Second, the legs 30 of the U-shaped opening in the top section 16 slope at roughly equal angles as the legs 30 of the U-shaped opening in the bottom section 18. Third, the top section 16 is approximately the same height as the bottom section 18. Fourth, the shelter floor 22 is generally flat, and the shelter roof 24 slopes very gradually.

[0036] The snug fit of inverted top sections within bottom sections and bottom sections within inverted top sections enables retailers to stack the shelters 10 in a bottom-top-bottom-top-bottom-etc arrangement. Thus, a large number of shelters 10 can be kept on hand by the retailer in a single, space-efficient stack. The space between each inverted top section 16 and bottom section 18 may include accessories for the shelter 10, such as a pad or a door. If such accessories are stored, the inverted top section and bottom section may be removably secured to retain the accessories therebetween and prevent loss or theft of the accessories.

[0037] The present invention also advantageously reduces the amount of warehouse space needed to store multiple pet shelters. Moreover, the present invention reduces transport costs of the shelters as more shelters fit within a standard shipping container.

[0038] In this configuration, the shelters 10 not only occupy relatively little inventory space, but a single shelter 10 can be removed from the top of the stack with minimal effort. Any accessories that the shelter 10 features may be already neatly packaged within. Furthermore, the snug fit of each section within the others leads to greater stability of a large stack. The stack is thus less prone to tipping over and causing injury.
