Abstract: A structural module includes a plurality of hollow cells having flat top ends, opposed open ends and side walls extending between both ends. The flat top ends are arranged in a first plane. Flat portions formed adjacent to the open ends of the cells are arranged in a second plane spaced from the first plane. The cells are arranged in adjacent parallel rows, with the side walls of cells in one row being co-linearly aligned with the side walls of cells in an adjacent row in a plane disposed at an acute angle with respect to the rows of cells.

Abstract: 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.

Abstract: A self-contained puzzle includes an axially extending tube with first and second end caps mounted on opposite ends. A plurality of gears are concentrically and rotatably mounted about the tube between the first and second end caps. Slide support elements on each of the gears form channels therebetween which slidably receive a slide element which is manipulatable from a channel in one gear to an aligned, empty channel in an adjacent gear. The exterior surfaces of the slide elements form a mosaic when assembled and contain indicia forming a puzzle or design. Releasable lock members are unitarily formed on one of the tube or each gear and releasably engage axially extending grooves formed in the other of the tube and each gear to temporarily lock each gear in a selected angular position about the tube relative to adjacent gears.

Abstract: Structural modules for incorporation in vehicle bodies, multiple part assemblies and other structures, utilizing a mixture of art based or simple geometric shapes increasing or decreasing, interrupted or uninterrupted in progression including honeycomb cells on parallel axes that can be bound together on an encompassing skin. These structures can be formed cast, sandwiched, or molded of plastic. The modules are shaped to fit various assembly areas and volumes especially those with curved or irregular contours.
