Abstract:
A foldable and extensible structure fabricated from one or more foldable and extensible base modules. Each base module is fabricated from six rigid members swivelly interconnected end-to-end in a closed figure with intersecting rigid members being pivotally connected. A plurality of base modules are selectively interconnected at adjacent swivels and, selectively, with additional rigid members or struts to thereby provide an enlarged, foldable and extensible truss-like structure. In one preferred embodiment, a plurality of base modules are interconnected in an end-to-end configuration to form an elongated, three-dimensional structure which folds into a triangular configuration having a relatively flat profile while, simultaneously, being extensible at a relatively high ratio to form the elongated structure. The base module can also be configurated as a collapsible and portable stool by being fitted with a triangular seat structure. The seat has a swivel-receiving pocket in each corner to individually receive one of the three swivels at one end of the base module.
