Abstract
Abstract There is disclosed a collapsible screen assembly for use in connection with enclosing and encircling an animal litter station formed by opposed sidewalls, a back wall and having an open front portion, and further including a removably engageable top wall, each of the opposed sidewalls being formed by a series of three sidewall panels, each being reversely hinge mounted to the next adjacent panel, the back wall being formed by a series of two back wall panels, each of the back wall panels being hingedly secured with one of the opposed sidewall panels thereby to accommodate only an interior hinge movement with respect to the back wall panel, and the top wall being formed by a series of three top wall panels wherein the first and third panels are reversely hinged mounted to the middle panel such that the opposed sidewalls may be reversely folded one panel with respect to the next with all panels being foldable against the two back wall panels which are in turn exteriorally hinge mounted together, and the top wall being foldable to a compact arrangement once removed from the screen assembly such that the entire screen assembly may be easily and compactly stored when not in use, and unfolded to form a surrounding screen assembly for an animal litter station.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
231 words
A collapsible screen assembly for encircling and enclosing an animal litter station, comprising in combination, a screen assembly formed by opposed sidewalls, a backwall and having an open front portion, each of said opposed sidewalls being formed by a plurality of sidewall panels, each of said sidewall panels being reversely hinge-mounted to the next adjacent wall panel, said backwall being formed by a back wall panel having one of each of said plurality of opposed sidewall panels hingedly secured thereto, said hinged securement permitting each of said opposed sidewall panels to travel only interiorally with respect to said backwall panel, and a top wall removably engaged to said opposed sidewall panels and said backwall panel by engagement means such that said top wall is removably engaged with each of said plurality of opposed sidewall panels and with said back wall panel thereby to provide rigidity and stability of said screen assembly when in use, whereby said screen assembly may be unfolded to provide a substantially total enclosure for an animal litter station while still permitting access thereto by the animal through said open front portion, and allowing said screen assembly to be completely folded into a compact storage posture by reverse folding of said opposed sidewall panels one with respect to the next adjacent panel, and interiorally folding said stack of opposed sidewall panels with respect to said back wall panel.
Claim 2
Dependent Claim
231 words
A collapsible screen assembly for encircling and enclosing an animal litter station, comprising in combination, a screen assembly formed by opposed sidewalls, a backwall and having an open front portion, each of said opposed sidewalls being formed by a plurality of sidewall panels, each of said sidewall panels being reversely hinge-mounted to the next adjacent wall panel, said backwall being formed by a back wall panel having one of each of said plurality of opposed sidewall panels hingedly secured thereto, said hinged securement permitting each of said opposed sidewall panels to travel only interiorally with respect to said backwall panel, and a top wall removably engaged to said opposed sidewall panels and said backwall panel by engagement means such that said top wall is removably engaged with each of said plurality of opposed sidewall panels and with said back wall panel thereby to provide rigidity and stability of said screen assembly when in use, whereby said screen assembly may be unfolded to provide a substantially total enclosure for an animal litter station while still permitting access thereto by the animal through said open front portion, and allowing said screen assembly to be completely folded into a compact storage posture by reverse folding of said opposed sidewall panels one with respect to the next adjacent panel, and interiorally folding said stack of opposed sidewall panels with respect to said back wall panel.
Claim 3
Dependent Claim
65 words
The screen assembly as set forth in claim 1 above, wherein said back wall panel is formed by a series of two back wall panels hingedly secured together and wherein each of said backwall panels is hingedly secured with one of said opposed sidewall panels being hingedly secured thereto such as to accommodate only an interior hinge movement with respect to said back wall panel.
Claim 4
Dependent Claim
48 words
A screen assembly as set forth in claim 2 above, wherein said screen assembly includes opposed sidewalls wherein each of said opposed sidewalls is formed by a series of three sidewall panels, each of said three sidewall panels being reversely hinge-mounted with respect to the next adjacent panel.
Claim 5
Dependent Claim
58 words
A screen assembly as set forth in claim 3 above wherein said top wall is formed by a series of three top wall panels, wherein said first and third panels are reversely hinge-mounted to said middle panel, whereby said top wall may be removably disengaged from said screen assembly and reverse folded to provide a compact storage posture.
Claim 6
Dependent Claim
46 words
A screen assembly as set forth in claim 4 above, wherein said engagement means comprises a friction bolt, each of said top wall panels including a pair of opposed friction bolts thereby to secure and engage said top wall to each of said opposed sidewall panels.
Claim 7
Dependent Claim
30 words
A screen assembly as set forth in claim 5 above, wherein said screen assembly further includes two friction bolts thereby to secure said top wall to said back wall panels.
Claim 8
Dependent Claim
39 words
A screen assembly as set forth in claim 6 above, wherein each of said back wall panels is provided with a friction bolt thereby to secure each of said two back wall panels to said corresponding top wall panel.
Claim 9
Dependent Claim
35 words
The screen assembly as set forth in claim 1 above wherein said screen assembly is further provided with opposed sidewalls wherein each of said sidewalls is provided with at least one aeration aperture disposed therein.
Claim 10
Dependent Claim
37 words
A screen assembly as set forth in claim 8 above, wherein each of said sidewall panels is provided with a single aeration aperture such that a total of six aeration apertures are provided in said screen assembly.
