Patent ID: 8839585

Claim:
A polyhedron truss constructed with a six-bar linkage structure forming each lateral facet of the polyhedron truss, the six-bar linkage structure comprising: six articulated struts, wherein each strut is coupled to two other struts by a revolute joint to form a closed loop; the six-bar linkage structure being convertible from a deployed state into a folded state and vice versa; in the deployed state, the six-bar linkage structure forming a trapezoid with two opposing first and second parallel sides, each of the first and second opposing parallel sides being formed by two struts arranged in series and coupled by a first and a second of the revolute joints, respectively, at the center of the first and second parallel sides; in the folded state, the two struts of the first side being pivoted around the first revolute joint so that the opposing end portions of the two struts are located side by side, and the two struts of the second side being pivoted around the second revolute joint so that the opposing end portions of the two struts are located side by side; the polyhedron truss being convertible from the deployed state into the folded state and vice versa by converting the six-bar linkage structures of the lateral facets from the deployed state into the folded state and vice versa; and in the deployed state, the polyhedron truss having a polygonal truncated pyramidal shape comprising an upper ring and a lower ring of articulated struts.
