Abstract:
A collapsible structure comprising:first and second collapsible flexible loop members, each loop member defining a closed loop and comprising a first and a second lower edge, each loop member further having an expanded position and a collapsed position, with the loop members overlapping each other at a first overlapping point along the first edges of the two adjacent loop members, and at a second overlapping point along the second edges of the two adjacent loop members, the overlapping loop members defining a hinge portion about which the two adjacent loop members are pivotable;a first fabric covering at least a portion of the first loop member, the first loop member substantially supporting the first fabric so that the first fabric assumes the configuration of the first loop member in the expanded position;a second fabric covering at least a portion of the second loop member, the second fabric including first and second separate fabric portions each having an inner edge, with the inner edge of each of the first and second fabric portions connected to the first fabric at the hinge portion, and with the second loop member substantially supporting the second fabric so that the first and second fabric portions assume the configuration of the second loop member in the expanded position.
