Patent attributes
A torsion box panel assembly includes a plurality of sub-panels each having a skin secured to a core, and a plurality of hinges each coupled between a different pair of the sub-panels such that each sub-panel is foldable relative to an adjacent sub-panel along a respective hinge. The hingedly-coupled sub-panels together form a base panel having an expanded configuration in which each hinge is closed and the surfaces of the sub-panel skins are substantially co-planar. The base panel, in its expanded configuration, has a planar panel surface defined, at least in part, by the combination of the co-planar sub-panel skins. At least one stabilizing member is secured to the planar panel surface and spans all of the closed hinges to lock the sub-panels together to form a torsion box panel.
