Abstract
A self-erecting shelter having a top, sides and floor made of a one-piece fabric envelope with a built-in armature made from a single and continuous length of steel wire coiled into two loops. The entire structure can be folded, twisted and bound into a flat circular package for transportation and storage. When released, the collapsed structure instantaneously springs back into a complete and fully erected shelter.
