The walls in the second pair (e.g. side walls) are pivotable toward an individual one of the platforms with the platform as a fulcrum to collapse the housing and toward the

8 other platform to expand the housing. In the collapsed housing disposition, detents on opposite sides of the hinge on the first pair of walls releasabiy engage to maintain the housing collapsed A manually grippable handle on one of the platforms provides for a transport of the collapsed housing. With the walls in the first pair expanded, detents on the walls in the first and second pairs of housings releasably engage to maintain the expanded housing enclosure. A second handle on one of the platforms is manually grippable to provide for the housing transport in the expanded relationship. Third detents provide fm a releasable closing and opening, preferably on a vertical axis, of a door in one of the second pair of walls. The walls in the first and second pairs are preferably ford from gratings of spaced wires to minimize weight and to provide a circulation of air through the housing from the atmosphere in the expanded housing.
Ashkins, et al., U.S. 5,727,502 describes a collapsible pef home having a base, side walls, end walls and a roof can be converted into an exercise pen for the pet by folding the end walls down onto the base, setting the base on end and using the base, side walls and roof to form peripheral walls of the exercise pen. An additional pen-forming module is provided to connect with the roof one side and one of the sidewalls on the other side to complete the peripheral wall of the exercise pen. The base may have a compartment for storing the additional module when it is not in use. The entire structure folds down into a compact package.
Koneke, U.S. 5,752,470 describes a collapsible system that can also be used for potable pet houses most types of small free standing buildings, as well as for emergency housing in times of disasters. The collapsible structure is better than a tent because it has real walls, a roof and has the feel of a home. The system can also be used for permanent housing, depending on building codes and types of materials used by making the structure portable, it is easy to move from place to place. It can also cut down on cost of moving large and bulky objects; and also

9 can cut down on packaging material. In the case of the housing, it cuts down on the cost of shipping. The record time that it takes to put up a collapsible structure also cuts down on manpower needed to set it up, thereby increasing quality control, because the collapsible structure can be made in a controlled factory environment and one can ship considerably more than what one could normally ship.
Deckys, U.S. 5,769,028 describes a carrier including a main unit and an insert unit. The main unit defines a carrying space having a closed bottom and four sides, one of which has an opening therethrough large enough to permit an animal to enter the space through the opening. The insert unit has a closed top, four sides, and an open bottom. After the animal has entered the main unit, the insert unit is lowered down into the main unit to close off the side opening.
Then a foldable top closure for the main unit is folded to secure the carrier and form a handle structure for carrying the carrier. Both units are foldable and are structured to provide an enhanced strength carrier. Strength enhancing features include the foldable bottom of the main unit, double and triple thickness portions of the top closure, and the presence of the insert unit in 'the main unit.
Axelrod et al., U.S. 5,950,568 describes a collapsiblelfoldable structure comprising a top roof and a bottom platform defining a top and bottom of the structure and a front and rear collapsible Mall each pivotally attached to the bottom platform to provide for pivotable collapse of the front and rear walls.
The structure further contains a pair of sidewalfs each pivotally attached to the roofi to facilitate inward collapse of said sidewails when said sidewalls are pivoted toward the bottom platform. The sidewalls further contain an upper, middle and lower section, wherein the upper and middle sections are pivotally attached to one another and the middle and lower section are also pivotally attached to one another so that the upper and middle sidewall sections can be pivoted inwardly towards the bottom platform. Furthermore, the top roof section further comprises two roof sections pivotally attached to one another at about the mid-point of the roof section, so that the two roof sections can collapse downwardly along the pivotable attachment toward the bottom platform. The collapsible) foldable structure herein is particularly useful as a shelter for domestic pets and other small animals.

The accompanying drawings illustrate the present invention. In such drawings:
Figure 1 is a perspective view of the preferred embodiment of the invention as erected; and Figure 2 is a perspective view thereof disassembled for storage.
DETAILED DESCRIPTION OF THE INVENTION
The above described drawing figures illustrate the invention in at least one of its preferred embodiments, which is further defined in detail in the following description.
The present invention is a shelter apparatus comprising an open box base member 1 having a bottom panel 1' and, extending upward therefrom, an integral, peripheral, box side wall 1" as shown in Fig. 1. This construction may be made of wood or plastic or other common rigid structural materials. A front and a rear 3 rigid shelter walls are removeably engaged in spaced apart vertical slots 7 in the box side wall 1 ". The walls 4, 3, are configured to slide into the slots 7 with frictional engagement so that the walls are not easily pulled out of the slots 7. An extensible beam 9, may be a spring tension type or a threaded extensive beam, both of which are well known. Beam 9 is engaged with, and extensive between the front and rear shelter walls 4, 3 and engages recesses in these walls as shown in Fig. 1. The beam 9 and recesses 11 may be threaded so that beam 9 may be threadedly engagable with recesses 11 for improved structural rigidity. Preferably beam 9 is made up of plural collinear segments in a telescoping, spring biased relationship. Vertical extension pieces 2, shown in Fig. 1 are mounted and engaged with walls 4, 3 to provide an improved structural reception of beam 9 above the contiguous walls 4, 3.
A flexible fabric cover 10 is extensive between opposing portions of the box side wall 1" and is draped, as shown in Fig. 1, over the front and rear sidewalk 4, 3.
The fabric cover 10 may be made of any material that is typically used for tents and the like, such as canvas ~r woven nylon, and is joined with the front and rear shelter walls 4, 3, and with the box side wall 1" by a surface fastening means such as Velcro, so that the box side wall 1 ", the front and rear shelter walls 4, 3, and the fabric cover 10 enclose a space for a pet such as a dog or cat. As shown, the surface fastening means 8 comprises thin strips laid along edges of the several elements described above. Preferably, the front and rear shelter walls 4, 3, have an integral base portion 12, or sill, that rests in contact with an upwardly facing edge 6 of the box side wall 1". This provides a footing far the shelter walls so that they are rigidly upright in light of the bias pressure exerted by the beam 9. The upwardly facing edge 5 is peripheral about the box side wall 1" and along each side, maintains the surface fastening means 8 for engaging fabric cover 10, as is clearly shown in Fig. 1.

As shown in Fig. 2, the peripheral box side wall 1" accepts the front and rear shelter walls 4, 3, stacked on top of the bottom panel 1' of the box base member 1 when the shelter is not in use or is being transported. The box side wall 1"
includes a pair of the opposing recesses 11 wherein the beam 9 may be engaged for securing the front and rear shelter walls 4, 3, and the fabric cover 10 between the beam 9 and the bottom panel 1' within the box base member 1'.
Preferably, at least one of the front and rear shelter walls 4, 3, provides a doorway aperture 5 for access by a pet to the interior of the shelter. A
flexible cover 5' is engaged over the doorway aperture 5 along the top portions of the aperture 5 and the cover 5' so that the flexible cover 5' is enabled for swinging into and out of the enclosed space. This is shown in Fig. 1 with dashed lines where the bottom portion of cover 5' is partially lifted. To accomplish this, the flexible cover 5' is only as wide as the aperture 5, and preferably slightly less wide. Preferably, a magnetic latch 14 is mounted on the sill 12 and on the bottom edge of the cover 5 so as to bias the flexible cover 5 into a vertical, closed attitude. Such bias is easily overcome by an animal moving against the cover 5 so that it does not impede use of this entry access.
While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims.
