ABSTRACT:
A collapsible truss structure having a shape of a rectangular parallelepiped when expanded is an open truss framework made up of skeletal members pin jointed together by joint connectors to form sixteen rectangular bays, four of which have diagonal braces, and supports panels for covering one face of the structure. The joint connectors permit the structure to be folded by power means in two directions into a compact slab for storage and/or transportation with the panels assembled therewith, while elastically biasing means automatically unfold the structure into its expanded state. Planar, single-curvature, and double-curvature panels can be thus supported. This structure can be optionally assembled with other structures to form larger structural assemblies.
