Abstract
Abstract The invention provides a basic building piece capable of combining with other, identical basic building pieces to form three-dimensional geometric models of the five regular polyhedrons (tetrahedron, hexahedron, octahedron, dodecahedron, and icosahedron), or more accurately, the Archimedean counterparts or truncated versions of these polyhedrons, as well as structures based on combinations of these solids, and other irregular and complex solids and shells. The basic building piece comprises a flat, generally hexagonal member carrying three types of fastening devices on its edges and surfaces to enable the desired variety of connection configurations with other, identical building pieces, and the structures resulting therefrom. In one embodiment, completed forms utilize the interplay of transparent colored pieces to create aesthetic patterns and multicolor relationships.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
166 words
A model building system comprising: a plurality of flat, generally hexagonal members each having six edge portions and a first surface; piece connector fastening means carried on three alternate edge portions of each of said hexagonal members, each piece connector conditioned for releasable engagement with the piece connector of another hexagonal member to join said members in edge-to-edge engagement; unit connector fastening means carried on the three alternate edge portions of each of said hexagonal members not occupied by said piece connectors, each unit connector conditioned for releasable engagement with the unit connector of another hexagonal member to join said members in edge-to-edge engagement; and face connector fastening means carried on each of said hexagonal members first surface, each face connector conditioned for releasable engagement with the face connector of another hexagonal member to join said members in face-to-face engagement; wherein said piece connectors are not engageable with said unit connectors or said face connectors, and said unit connectors are not engageable with said face connectors.
Claim 2
Dependent Claim
166 words
A model building system comprising: a plurality of flat, generally hexagonal members each having six edge portions and a first surface; piece connector fastening means carried on three alternate edge portions of each of said hexagonal members, each piece connector conditioned for releasable engagement with the piece connector of another hexagonal member to join said members in edge-to-edge engagement; unit connector fastening means carried on the three alternate edge portions of each of said hexagonal members not occupied by said piece connectors, each unit connector conditioned for releasable engagement with the unit connector of another hexagonal member to join said members in edge-to-edge engagement; and face connector fastening means carried on each of said hexagonal members first surface, each face connector conditioned for releasable engagement with the face connector of another hexagonal member to join said members in face-to-face engagement; wherein said piece connectors are not engageable with said unit connectors or said face connectors, and said unit connectors are not engageable with said face connectors.
Claim 3
Dependent Claim
27 words
The model building system of claim 1 wherein said piece connector edge-to-edge engagement enables hinged movement of said joined member from coplanarity to either side of non-coplanarity.
Claim 4
Dependent Claim
27 words
The model building system of claim 1 wherein said unit connector edge-to-edge engagement enables hinged movement of said joined members from coplanarity to either side of non-coplanarity.
Claim 5
Dependent Claim
48 words
The model building system of claim 1 having a first hexagonal member and a second hexagonal member, wherein said face connector joins said members in face-to-face engagement only when the piece connectors of said first hexagon member are positioned proximate the unit connectors of said second hexagonal member.
Claim 6
Dependent Claim
84 words
The model building system of claim 1 having a first hexagonal member and a second hexagonal member, wherein said face connector joins said members in face-to-face engagement only when the piece connectors of said first hexagonal member are positioned proximate the unit connectors of said second hexagonal member, and when the unit connectors of said first hexagonal member are positioned proximate the unit connectors of said second hexagonal member, said unit connectors enable joining of said first and second hexagonal members in face-to-face engagement.
Claim 7
Dependent Claim
26 words
The model building system of claim 1 wherein four of said hexagonal members joined together in edge-to-edge engagement by said piece connectors form a truncated tetrahedron.
Claim 8
Dependent Claim
26 words
The model building system of claim 1 wherein eight of said hexagonal members joined together in edge-to-edge engagement by said piece connectors form a truncated octahedron.
Claim 9
Dependent Claim
26 words
The model building system of claim 1 wherein twenty of said hexagonal members joined together in edge-to-edge engagement by said piece connectors form a truncated icosahedron.
Claim 10
Dependent Claim
140 words
A model building piece comprising: a flat, generally hexagonal member having six edge portions and a first surface; piece connector fastening means carried on three alternate edge portions of said hexagonal member, each piece connector conditioned for releasable engagement with a piece connector of another similar hexagonal member; unit connector fastening means carried on the three alternate edge portions of said hexagonal member not occupied by said piece connectors, each unit connector conditioned for releasable engagement with a unit connector of another similar hexagonal member; and face connector fastening means carried on said hexagonal member first surface, each face connector conditioned for releasable engagement with a face connector of another similar hexagonal member; wherein said piece connectors, said unit connectors, and said face connectors are only engageable with respective piece connectors, unit connectors, and face connectors of similar hexagonal members.
Claim 11
Dependent Claim
140 words
A model building piece comprising: a flat, generally hexagonal member having six edge portions and a first surface; piece connector fastening means carried on three alternate edge portions of said hexagonal member, each piece connector conditioned for releasable engagement with a piece connector of another similar hexagonal member; unit connector fastening means carried on the three alternate edge portions of said hexagonal member not occupied by said piece connectors, each unit connector conditioned for releasable engagement with a unit connector of another similar hexagonal member; and face connector fastening means carried on said hexagonal member first surface, each face connector conditioned for releasable engagement with a face connector of another similar hexagonal member; wherein said piece connectors, said unit connectors, and said face connectors are only engageable with respective piece connectors, unit connectors, and face connectors of similar hexagonal members.
Claim 12
Dependent Claim
18 words
