Abstract
Abstract The body of the shelter is formed of a plurality of identical panels two of which form the end walls and the other two of which form the back wall. The panels of the back wall are hinged to each other by flexible strips and are similarly hinged to the back edges of the side walls. Flexible sheets form the top and bottom of the shelter and allow for the hinging of the two back wall panels relative to each other and the hinging of the end wall panels relative to the back wall so that the body of the structure can be folded flat. A visor shields the top of the open front, and a novel apron covers the lower part of the front and extends over the knees of an occupant or occupants of the shelter, the height of the upper edge of the apron being adjustable.

A temporary portable shelter comprising relatively rigid self-sustaining end walls and a back wall extending therebetween, means movably connecting each end wall to the adjacent end of said back wall, a flexible sheet extending over the tops of and sealed to said end and back walls, a flexible sheet similarly connected to the lower extremities of said end and back walls, and means engaging the top and bottom portions of said end walls and forcing them away from each other to stretch said flexible sheets.
Claim 2
Dependent Claim
85 words
A temporary portable shelter comprising relatively rigid self-sustaining end walls and a back wall extending therebetween, means movably connecting each end wall to the adjacent end of said back wall, a flexible sheet extending over the tops of and sealed to said end and back walls, a flexible sheet similarly connected to the lower extremities of said end and back walls, and means engaging the top and bottom portions of said end walls and forcing them away from each other to stretch said flexible sheets.
Claim 3
Dependent Claim

A structure according to claim 1 wherein said back wall is formed of two vertical panels having abutting edges centrally of the length of said back wall and a hinge secured against said panels adjacent said abutting edges rearwardly of said back wall whereby the central portions of said back wall are movable forwardly for folding said panels, and hinges connecting the rear edges of said end walls to said back wall and positioned for the inward swinging of said end walls.
Claim 4
Dependent Claim
31 words
The structure according to claim 2 wherein said end walls are in the form of panels identical with the panels of said back wall, said panels being formed of molded plastic.
Claim 5
Dependent Claim
45 words
