Abstract

Abstract Two rigid, upstanding elongated sidewalls positioned in generally parallel relationship and movable between adjacent and spaced-apart positions, two foldable end walls affixed between the sidewalls at opposite ends thereof, a foldable floor affixed between the sidewalls and a roof having a central inverted Vshaped member with two outwardly projecting extensions thereof hingedly affixed to the central member so as to hang vertically downwardly adjacent the outer surfaces of the sidewalls in the collapsed position and to assume an overlying relationship to the sidewalls in the assembled position. A plurality of struts hingedly connected between the outer surfaces of the sidewalls and the under surfaces of the projecting members of the roof to maintain the roof in an assembled position while the sidewalls are being moved from a collapsed position to the assembled position, the struts forming generally vertically decorative battens on the exterior of the sidewalls and holding the roof in place.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 119 words
A collapsible housing unit comprising: a. a roof having a plurality of members pivotally affixed together, said roof members having a collapsed position and a pivotally spaced assembled position; b. two rigid upright elongated members mounted for transverse movements between a collapsed position and a transversely spaced assembled position, said elongated members forming two opposed sidewalls of the unit in the assembled position; and c. means pivotally connected to said roof and to said elongated members for maintaining said roof in the assembled position after movement thereto from the collapsed position and during movement of the elongated members from the collapsed to the assembled position and for maintaining said roof affixed to said elongated members in the assembled position.
Claim 2
Dependent Claim 119 words
A collapsible housing unit comprising: a. a roof having a plurality of members pivotally affixed together, said roof members having a collapsed position and a pivotally spaced assembled position; b. two rigid upright elongated members mounted for transverse movements between a collapsed position and a transversely spaced assembled position, said elongated members forming two opposed sidewalls of the unit in the assembled position; and c. means pivotally connected to said roof and to said elongated members for maintaining said roof in the assembled position after movement thereto from the collapsed position and during movement of the elongated members from the collapsed to the assembled position and for maintaining said roof affixed to said elongated members in the assembled position.
Claim 3
Dependent Claim 47 words
A collapsible housing unit as set forth in claim 1 including vertically foldable end members pivotally affixed to between the elongated members at each end thereof, said end members having a collapsed and an assembled position and forming end walls for the unit in the assembled position.
Claim 4
Dependent Claim 53 words
A collapsible housing unit as set forth in claim 1 including a plurality of vertically extending columns affixed to said elongated members and spaced horizontally inwardly from the sidewalls of the unit in the assembled position, said columns providing substantially support for the unit to at least partially relieve stress in the sidewalls.
Claim 5
Dependent Claim 34 words
A collapsible housing unit as set forth in claim 1 wherein the pivotally connected means includes a plurality of elongated struts extending between the roof and the elongated members, external of the elongated members.
Claim 6
Dependent Claim 45 words
A collapsible housing unit as set forth in claim 1 having in addition a foldable floor affixed to the two elongated members and forming an upwardly directed generally planar surface between said two elongated members when said elongated members are moved into the assembled position.
Claim 7
Dependent Claim 71 words
A collapsible housing unit as set forth in claim 1 wherein rollers and clamps are affixed to the underside of each of the two elongated members and the unit includes a base formed of a plurality of transversely extending rigid members positioned to receive the rollers thereon in rolling engagement, with the clamps positioned to engage the base and prevent disengagement of said rollers from the rigid members of said base.
Claim 8
Dependent Claim 58 words
A collapsible housing unit as set forth in claim 1 wherein the roof includes a central inverted V-shaped portion and a generally flat portion hingedly affixed to each side of said central portion so as to hang vertically downwardly in the collapsed position and forming a continuation of the side of said central portion in the assembled position.
Claim 9
Dependent Claim 224 words
A collapsible housing comprising: a. first and second side members each including a rigid sidewall and a plurality of vertical columns spaced inwardly from said sidewall; b. first and second end walls affixed between opposite ends of said side members, said end walls being transversely retractable and extendable between a collapsed position wherein said side members are in juxtaposition and an assembled position wherein said side members are spaced transversely apart; c. a foldable floor affixed between said side members and movable Between a collapsed and an assembled position as said side members are moved between adjacent and spaced apart positions; d. a first roof member having a generally inverted V-shape and a transverse dimension sufficient to generally overlie said first and second side members in the adjacent or collapsed position; e. second and third roof members hingedly affixed to opposed sides of said first roof member with adjacent edges of said roof member in generally parallel mating relationship; and f. a plurality of struts each pivotally connected adjacent one end to the underside of one of said second and third roof members and pivotally connected adjacent the other end to the external side of one of said first and second side members, said struts assuming a generally vertical position with said first and second side members in the spaced apart or assembled position.
Claim 10
Dependent Claim 224 words
A collapsible housing comprising: a. first and second side members each including a rigid sidewall and a plurality of vertical columns spaced inwardly from said sidewall; b. first and second end walls affixed between opposite ends of said side members, said end walls being transversely retractable and extendable between a collapsed position wherein said side members are in juxtaposition and an assembled position wherein said side members are spaced transversely apart; c. a foldable floor affixed between said side members and movable Between a collapsed and an assembled position as said side members are moved between adjacent and spaced apart positions; d. a first roof member having a generally inverted V-shape and a transverse dimension sufficient to generally overlie said first and second side members in the adjacent or collapsed position; e. second and third roof members hingedly affixed to opposed sides of said first roof member with adjacent edges of said roof member in generally parallel mating relationship; and f. a plurality of struts each pivotally connected adjacent one end to the underside of one of said second and third roof members and pivotally connected adjacent the other end to the external side of one of said first and second side members, said struts assuming a generally vertical position with said first and second side members in the spaced apart or assembled position.
