    Abstract: A standard structural building module which is a three-dimension triangulated truss, capable of being retracted into a compact package for storage and shipment and then expanded on site for erection and connection to similar modules. Modules may be joined side-by-side or end-to-end to construct many structural forms such as, for example, a bridge in the horizontal orientation or a tower in the vertical orientation. A structure may be sized to support any magnitude or mode of loading by adding modules until adequate strength is attained.

    Abstract: An expandable-retractable structure which in its simplest form comprises: a first set of three rigid links connected together by a first primary pivot at one end, a second set of three rigid links connected together by a second primary pivot at one end and pivotally joined to the first set of links by means of three secondary pivots each connecting corresponding links of said two sets, and a set of three bracing cables connecting the three secondary pivots to complete a double tetragonal structure. The structure is usable as a single module or in combination with a plurality of similar modules which, when combined with connecting cables, may form flat, tapered, or curved structures such as bridges, towers, outriggers, and scaffolds. An actuation system is provided comprising an extension cable connecting the primary pivots which when subjected to tension urges said first and second primary pivots toward one another, subjecting the bracing cables to tension and thereby stabilizing the structure, and a retraction means comprising cables connecting the three secondary pivots which when subjected to tension urge the secondary pivots toward one another and the primary pivots away from one another to return the structure to its original retracted form.
