Image Number 4 for United States Patent #5236196.
A spherical body is formed of a plurality of polygonal-shaped members interconnected together at abutting side walls. Each polygonal member has an exterior surface disposed at a predetermined radius of curvature, with the exterior surfaces of the plurality of interconnected polygonal members forming the exterior surface of the spherical body when the members are joined together. In one embodiment, the polygonal members comprise pentagon-shaped members such that the spherical body is completely formed of identical, pentagon-shaped members. Various designs may be formed in the exterior surface of each polygonal member by use of raised and recessed portions in the exterior surface, as well as having certain portions of the exterior surface of each polygonal member devoid of material.
