ABSTRACT:
A portable self-erecting tent structure makes use of a pair of flexible, coilable, resilient bands, such as spring steel bands, to form the frame of the tent. One band can be folded to nest into the other and the two nested bands can be twisted until they assume a coiled, but stable, configuration for storage or transport. The tent is self-erecting since disturbing the coiled configuration of the bands causes them to uncoil, and the resilience of the bands and the springs connecting them then causes the frame of the tent to erect itself.
