Abstract: A collapsible enclosure that generally comprises a symmetrical pair of base members and a pliable protective cover supported by a plurality of internal frame members pivotally connected on the axis of the hinge points for the base members. By manually rotating the first frame member about its axis, the protective cover and additional frame members unfurl over the base members and surround a vehicle or object in a shell-shaped enclosure. To store or transport the enclosure, the protective cover and frame members collapse in an accordion-like fashion and sandwich between the folded base members.
