Abstract
Abstract A COLLAPSIBLE STRUCTURE FOR USE IN CONSTRUCTION COMPRISING AT LEAST TWO PANELS AND AT LEAST ONE ELASTOMERIC STRIP, BRIDGING THE SEAM BETWEEN THE PANELS AND BONDED TO THE REAR OF THE PANELS IN A MANNER SUCH THAT THE STRIPS FUNCTION AS ELASTOMERIC HINGES. THESE HINGES ARE DESIGNED SO THAT THEY WILL STRETCH TO ALLOW THE PANELS TO BE POSITIONED IN ANY ANGULAR RELATION TO ONE ANOTHER, AND CONTRACT WHEN THE PANELS ARE FINALLY POSITIONED, TO INSURE THAT THE FRONT SURFACES OF THE PANELS ARE CONTIGUOUS. WHEN THE PANELS, ELASTOMERIC STRIPS AND BONDS ARE WATER RESISTANT, THE HINGE ACTS AS A SEAL AND THE STRUCTURE IS USEFUL AS A PREFABRICATED BATHTUB SURROUND PACKAGE.
