Abstract
Collapsible structures are provided having at least two panels, with each of the panels having a flexible loop member defining a closed loop and adapted to assume an expanded position and a collapsed position, and a fabric for partially covering the loop member. The loop members of two adjacent first and second panels overlap each other at a first overlapping point along first edges of the loop members, and at a second overlapping point along second edges of the loop members, with the overlapping loop members defining a hinge portion about which the two loop members of the first and second panels are pivotable.
Claims12
A structure comprising:
- a first flexible loop member having a closed loop adapted to assume an expanded position and a collapsed position;
- a first fabric that covers portions of the first flexible loop member;
- a second flexible loop member having a closed loop adapted to assume an expanded position and a collapsed position;
- a second fabric that covers portions of the second flexible loop member;
- wherein the first and second loop members overlap each other at first and second overlapping points that are spaced apart along the first and second flexible loop members;
- and
- wherein a portion of the first fabric crosses a portion of the second fabric to form an X-shaped configuration between the first fabric and the second fabric.
