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.
