Abstract: This invention discloses tongs-linkage, which, in its extended position, provides an essentially triangular-shaped surface, whereby the links of the tongs-linkage are themselves the panels that form the surface. Such assemblies may be planar, or, by use of intermediate hub elements, may form a surface with curvature. As such an assembly is compressed, the panel-links slide over one another, compressing down to a compact stack. Such tongs-linkages may be joined to similar linkages by pivots lying along their respective edges thereby forming extended structural surfaces. Surfaces that are planar, cone-shaped and doubly-curved surfaces of revolution are disclosed. In each case when the structure is retracted it compresses down to a compact linear element or ring.
