ABSTRACT:
A collapsible portable shelter or changing room comprising a body of circular bellows like configuration capable of manufacture on current plastic mold equipment with current plastic materials. The bellows like walls overlap vertically and integrally down the side around a large aperture in a spring-like manner from tension on the rib folds by manual downward pressure. The accordion-like wall, when fully collapsed, substantially fits within an optional carry case fastened to the shelter floor. The structure is raised for use from a collapsed into an extended form by manual release of fasteners, causing the bellows wall to spring upward, without assistance, providing a large interior volume sufficient to enclose a person for use as a toilet shelter or changing room.
