ABSTRACT:
A tubular, ribbed, elevatable sleeping shelter that is compressible to a size convenient for carrying by an individual. In its preferred form, the shelter has three circular, sectioned ribs, each having a removable, handle-like projection across the bottom which serves as an elevating means. Each rib is comprised of four sections, the top section being smaller in circumference to allow its partial insertion inside the hinged side sections for consolidation purposes. The ribs are separated by braces along each side and the floor, and a cover is provided for the floor braces. The angular shape of the brace connections serves to hold the structure upright. Rotatable floor connections and optional use of adjustment extensions ensure that the unit sets firmly on the ground and reduces the risk of warping of the brace connections. A cover encloses the circumference of the ribs and is secured at the bottom between the ribs and elevating projections. A closure at each end is attachable by means of a double zipper. Ventilation can be controlled from within. Assembly or disassembly can quickly and easily be achieved.
