Patent ID: 7118442

Claim:
A polyhedron constructed of identical construction members each having a longitudinal dimension with a first end and a second end, with complementary end rotational joint portions at the first end and at the second end, and a longitudinal rotational joint portion in the longitudinal dimension, the polyhedron comprising: polygons, each said polygon having at least three of the identical construction members connected first end to second end so as to form end rotational joints with the complementary end rotational joint portions; edges, each said edge being formed by a pair of the identical construction members of adjacent polygons being connected side-by-side so as to form a longitudinal rotational joint with the longitudinal rotational joint portions, each said edge being colinear with a longitudinal rotational axis of the longitudinal rotational joint; and vertices, each said vertex being formed by an intersection of at least three of the longitudinal rotational axes of three or more of said polygons.
