Abstract:
A structure comprising:(a) a first panel, a second panel, a third panel, and a fourth panel, each of the panels having:a flexible loop member defining a closed loop and having a first edge and a second edge, the loop member adapted to assume an expanded position and a collapsed position;a fabric that covers portions of the loop member; anda left side and a right side defined by the loop member;(b) wherein the loop members of the first and second panels overlap each other at a first overlapping point along the first edges of the loop members of the first and second panels, and at a second overlapping point along the second edges of the loop members of the first and second panels, the overlapping loop members defining a hinge portion about which the first and second loop members of the first and second panels are pivotable;(c) wherein the loop members of the second and fourth panels overlap each other at a third overlapping point along the first edges of the loop members of the second and fourth panels, and at a fourth overlapping point along the second edges of the loop members of the second and fourth panels, the overlapping loop members defining a second hinge portion about which the second and fourth loop members of the second and fourth panels are pivotable; and(d) wherein one side of the third panel is hingedly connected to one side of the first panel, and the other side of the third panel is hingedly connected to one side of the fourth panel.
