ABSTRACT:
A structure is described that has an open and closed configuration. In the open configuration, the structure is free standing and is able to support weight. In the closed configuration, the structure is flat. The structure is formed of two elements that are interlocked at their corners in a manner that allows them to pivot with respect to each other. Chamfered surfaces on the sides of the elements provide stops limiting the motion between the elements. Several structures may be combined to form composite products.
