Abstract

A shelter has a framework of resilient wire in two separate closed loops. Both loops have a memory urging them to lie circularly in a flat plane. Each loop is elongated with one longitudinal end portion partially curled back toward an opposite end portion with the curled end portion being an arch for providing vertical support and the opposite end portion being a generally U-shaped footing member. One loop extends through the other, preferably symmetrically, such that the footing members are opposingly disposed in relation to each other to provide generally planar footing support for the shelter, e.g. the footing members are substantially coplanar with the closed ends of their U-shapes facing outward in opposite directions, and such that the support arches are opposingly aligned and spaced apart, the spacing defining the width of the shelter's ceiling. The loops are kept curled and held in relation to each other by restraining sleeves which are affixed to the external surface of an envelope which at least partially encloses a volume defined by the framework. The respective memories in the loops urging them to outwardly uncurl in opposite directions act to keep the envelope taut.
