Abstract:
A collapsible structure, comprising:first and second flexible loop members, each loop member defining a closed loop and having a first edge and an opposing second edge, each loop member adapted to assume an expanded position and a collapsed position, with the two loop members overlapping each other at a first overlapping point at about the center of the first edges of the loop members, and at a second overlapping point at about the center of the second edges of the loop members;wherein the loop members are adapted to assume a deployed position in which one loop member is disposed at an angle with respect to the other loop member at the overlapping points, and with the loop members further defining at least four sides when in the deployed position with the loop members being twisted and folded into a smaller configuration when in the collapsed position; anda flexible wall having portions permanently attached to the loop members and extending across portions of at least two of the four sides.
