ABSTRACT:
Collapsible structure are provided having a first base panel and a second panel, each having a foldable frame member that has a folded and an unfolded orientation, and a material partially covering the frame member when the frame member is in the unfolded orientation, with the material assuming the unfolded orientation of its associated frame member. The second panel is flexed so that the first and second panels define an interior space, with the second panel having opposing first and second end edges that are coupled to the outer periphery of the first panel. The second panel can have two or more supporting frame members to allow the collapsible structures to be provided in different configurations and sizes. In addition, the first base panel can be replaced by a fabric or similar piece of material that is coupled to the first and second end edges of the second panel. The second panels can be coupled within, or outside, the outer periphery of the first base panel or fabric.
