ABSTRACT:
BACKGROUND OF THE INVENTION
INCORPORATION BY REFERENCE: Applicant(s) hereby incorporate herein by reference, any and all U.S. patents, U.S. patent applications, and other documents and printed matter cited or referred to in this application.
1. Field of the Invention:
This invention relates generally to portable pet shelters and pet houses, and more particularly to portable folding pet shelter of simple and light weight construction.
2. Description of Related Art:
The following art defines the present state of this field:
Paschke, U.S. Pat. No. 2,793,401 describes a small building construction comprising, a rectangular base wall having an upstanding peripheral flange secured thereabout, a plurality of upstanding paneled side walls each having a bottom edge supported in mating relation upon said upstanding peripheral flange and each having a depending marginal rail lying in laterally offset relation with respect to the bottom edge, said rail abutting laterally the upstanding peripheral flange, each of said side walls further having a top edge and a pair of side edges and being releasably connected to a side edge of another side wall, a roof panel interlockably connected to the top edges of the respective side walls, and cooperative fastening means formed laterally on opposed abutting portions of said upstanding peripheral flange and each of the marginal rails, whereby in the disassembly of said building construction said roof may be removed from its interlocking connection with the top edges of the side walls and each of the walls then rocked on its bottom edge to separate its rail from the abutting peripheral flange and thereby to disengage the cooperative fastening means and to release the side edge connection.
Kuhn, U.S. Pat. No. 3,132,443 describes a beam and column construction for a building toy comprising, a vertical column, a longitudinally extending lug projecting from the lower end thereof and a lug receiving socket recessed in the upper end thereof, a longitudinally extending projection disposed at each corner of said upper end and spaced from each other, each projection forming with its adjacent projection a tenon receiving mortise, and a beam having on at least one end thereof a tenon lodged in said mortise, said socket having vertically extending walls, the end surface of said tenon, when lodged in said mortise, forming one wall of an extension of said socket.
Palencia, U.S. Pat. No. 3,234,907 describes an animal cage comprising in combination; a plurality of substantially vertically disposed lateral wall sections with the opposite ends of each of said wall sections being in juxtaposition with an end of an adjacent wall section and forming at least two pairs of ends in juxtaposition, a slidable clip fastener disposed outwardly of said wall sections in removable slidable engagement with each said pair of ends in juxtaposition and normally holding said wall sections in assembled relationship, one of said slidable clip fasteners forming a hinged connection between one of said pair of ends in juxtaposition, a pair of ends spaced from said hinged connection being movable into laterally spaced relationship when one of said slidable clip fasteners is slidably disengaged from said pair of ends, each of said wall sections having at the lower edge thereof a marginal flange extending inwardly in a plane substantially perpendicular to the vertical plane of each said wall sections and providing a transverse supporting surface for engaging the lower surface of a floor member, and a floor member freely supported between said wall sections by said flanges; whereby said floor member is readily removable from said wall sections when said wall sections are moved into laterally spaced relationship after slidably removing one of said slidable clip fasteners from engagement with said wall sections.
Falcone et al., U.S. Pat. No. 3,478,722 describes a bird house comprising an apartment of quadrangular form having a bottom wall, opposite side walls, and a rear wall, certain of said walls being joined together by an integral hinged joint, said side walls being formed with projections extending upwardly from the upper edges thereof, said bottom wall being formed with apertures spaced complemental to said projections said side wall projections on a first apartment entering the apertures in the bottom wall of similar apartment superimposed on said first apartment, said projections serving to interlock said apartments arranged in vertical stack formation, and means cooperable with said side and end walls for detachably connecting apartments together in spaced lateral relation to form a multiple apartment dwelling.
Sou, U.S. Pat. No. 4,256,056 describes a portable case, into which the pet fancier puts his small animal and carries it about, wherein the main body of the case is constructed by putting together a pair of side wall boards, a top board connected at its left and right sides to the respective upper end faces of the left and right side wall boards through the aid of hinged joints, and a bottom board connected at its left and right sides to the respective lower end faces of the left and right side wall boards likewise as above through the aid of hinged joints, which main body of the case is furnished at its front and rear sides with the respective on-off door leaves, and the case thus constructed can be simply folded up by opening both the door leaves.
Binkert, U.S. Pat. No. 4,576,116 describes a collapsible A-frame house providing a common site for a cat to rest, exercise and play comprised of a roof of carpet-like material including two integral roof panels with their bottom edges connected to opposing edges of a floor panel also of carpet-like material. Stiffening panels are affixed onto the backside of the roof panels. A cord has two ends slidably passing through the peak into the house, with cat amusement objects connected to each end. The cord additionally provides a manual handle for lifting the house.
Williamson, U.S. Pat. No. 4,792,082 describes a litter box including an outer front sidewall, an outer rear sidewall, an outer left sidewall, a cover member, and an outer right sidewall. The litter box is formed from a single integral cardboard sheet which, when folded in an appropriate fashion, results in an enclosed, disposable litterbox. The box may be shipped with a supply of litter enclosed, and may be shipped and stored in a rectangular package of approximately 2 inches in height.
Spina, U.S. Pat. No. 4,869,206 describes an animal cage for permitting collection of solid and liquid animal wastes for analysis. The cage comprises a top, bottom and four sides connected together to define an enclosure, a first floor positioned above the bottom. The first floor has a slope along its full dimension to a single lowest point. A second floor supports an animal and positioned above the first floor. The floor includes perforations for permitting liquid waste to pass therethrough onto the sloped first floor while retaining solid wastes thereon and a litter holder for providing a location for instinctive animal elimination of solid and liquid wastes. The litter holder communicates with the perforations for permitting liquid to pass from the litter holder through the second floor onto the first floor. A liquid collector cooperates with the first floor at its lowest point for permitting collection of liquid flowing there.
Devault, U.S. Pat. No. 4,903,637 describes a container, to house or carry small household pets that may be quickly and manually formed between an erected use mode and a flat folded storage mode. The container is of gable roofed house configuration in its erected mode and comprises an interconnected structure formed by hingeably related rigid planar elements that occupy a relatively small volume in the folded storage mode. Handles carried by the roof provide aid in manual carriage, releasable fasteners maintain either erected or storage mode, and an end wall provides a selectively latchable door.
Taft, U.S. Pat. No. 5,014,649 describes a pasteboard cat litter structure compr
