Patent ID: 8365677

Claim:
A foldably constructed force-resisting structure comprising: a top member formed from a top member base panel having a perimeter comprising a plurality of side edges, two diagonally opposed corners, and a top member side portion foldably connected to one of the side edges and folded to a position substantially perpendicular to said top member base panel; a bottom member formed from a bottom member base panel having a perimeter comprising a plurality of side edges and two diagonally opposed corners, a bottom member side portion foldably connected to one of the side edges of said bottom member base panel, a cut-out opening located in said bottom member base panel, and a plurality of bottom member interior support ribs, each of said support ribs comprising a pair of rib panels interconnected at a crest fold line and outer side edges connected to said bottom member base panel at respective base fold lines, the crest fold lines extending diagonally from the respective corners, the rib panels being folded to an extended position substantially perpendicular to said bottom member base panel with the base fold lines adjacent one another, said opening being collapsed when said support ribs are in said extended position, said bottom member side portion being folded to a position substantially perpendicular to said bottom member base panel; and said bottom member being assembled to said top member in nested relation, said support ribs defining an X-shaped support structure disposed between said base panels, said top member base panel supported on said support structure in substantially parallel relation to said bottom member base panel, said top member and said bottom member defining a peripheral side of said force-resisting structure defined at least in part by said side portions and an interior between said base panels, said peripheral side having an opening therein providing access to the interior.
