Abstract

Abstract Disclosed is a portable structure, a principal utility for which is a tent or the like. The support for the structure typically comprises a continuous loop of a flexible coilable resilient material such as flat spring steel stock. The support is secured to the fabric of the structure at a plurality of points and is preferably continuously held thereto in an elongate pocket. In use, the support is restrained by and supports the fabric and assumes a complex shape dictated by its size and shape of the fabric. Most commonly, the support and the fabric bounded thereby, in use, assumes a generally saddle-shaped configuration. The coilable frame allows the structure to be readily collapsed and virtually self erecting.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 147 words
A tent comprising a body of flexible, sheet-like material, a closed loop of a flexible, coilable, springy material as a frame member therefor, said frame member being secured to the periphery of said body in a generally saddle-shaped configuration including two opposed smoothly curved upper ends and opposed smoothly curved lower ends spaced therebetween said lower ends being adapted to be supported by the ground along a limited length thereof, said frame including said length being insufficient to provide stable support to the tent, end panels affixed to said body at each end thereof to form therewith a closed structure said end panels extending beyond the horizontal extent of said body and ties at the lower corners of the end panels adapted to secure the tent to the ground and thereby stably support and tension the tent and hold the frame in the saddle-shaped configuration in use.
Claim 2
Dependent Claim 147 words
A tent comprising a body of flexible, sheet-like material, a closed loop of a flexible, coilable, springy material as a frame member therefor, said frame member being secured to the periphery of said body in a generally saddle-shaped configuration including two opposed smoothly curved upper ends and opposed smoothly curved lower ends spaced therebetween said lower ends being adapted to be supported by the ground along a limited length thereof, said frame including said length being insufficient to provide stable support to the tent, end panels affixed to said body at each end thereof to form therewith a closed structure said end panels extending beyond the horizontal extent of said body and ties at the lower corners of the end panels adapted to secure the tent to the ground and thereby stably support and tension the tent and hold the frame in the saddle-shaped configuration in use.
Claim 3
Dependent Claim 13 words
A tent of claim 1 including a floor affixed to said end panels.
Claim 4
Dependent Claim 18 words
The tent of claim 1 wherein said end panels include mesh portions to provide ventillation of the structure.
Claim 5
Dependent Claim 13 words
The tent of claim 3 including a floor affixed to said end panels.
Claim 6
Dependent Claim 22 words
The tent of claim 1 including additional saddle-shaped body panels and frame members associated therewith and connecting panels between said body panels.
