Abstract
Abstract A set of tiles for covering a surface is composed of two types of tile. Each type is basically quadrilateral in shape and the respective shapes are such that if a multiplicity of tiles are juxtaposed in a matching configuration, which may be prescribed by matching markings or shapings, the pattern which they form is necessarily non-repetitive, giving a considerable esthetic appeal to the eye. The tiles of the invention may be used to form an instructive game or as a visually attractive floor or wall covering or the like.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
127 words
A set of tiles for covering a plane surface comprising (a) a plurality of identical tiles of a first shape, five of said tiles assembled together around a center of five-fold symmetry mating along identical lines successively spaced by angles of 72° to produce a basic continuous assemblage without interstices or overlaps, and (b) a plurality of identical tiles of a second shape different from said first shape said tiles of said second shape mating with tiles both of said first and said second shape to develop said basic continuous assemblage in all directions without interstices or overlaps to produce a greater assemblage of indefinite extent, said greater assemblage exhibiting localizd features of five-fold symmetry, being non-repeating, and being characterized by the absence of a period parallelogram.
Claim 2
Dependent Claim
127 words
A set of tiles for covering a plane surface comprising (a) a plurality of identical tiles of a first shape, five of said tiles assembled together around a center of five-fold symmetry mating along identical lines successively spaced by angles of 72° to produce a basic continuous assemblage without interstices or overlaps, and (b) a plurality of identical tiles of a second shape different from said first shape said tiles of said second shape mating with tiles both of said first and said second shape to develop said basic continuous assemblage in all directions without interstices or overlaps to produce a greater assemblage of indefinite extent, said greater assemblage exhibiting localizd features of five-fold symmetry, being non-repeating, and being characterized by the absence of a period parallelogram.
Claim 3
Dependent Claim
35 words
A set of tiles according to claim 1 wherein five of said tiles of said second shape assembled together around a center of five-fold symmetry mate along identical lines successively spaced by angles of 72°.
Claim 4
Dependent Claim
28 words
A set of tiles according to claim 1 wherein said first shape comprises a quadrilateral with straight sides, and said second shape comprises a quadrilateral with straight sides.
Claim 5
Dependent Claim
27 words
A set of tiles according to claim 1 wherein the identical lines, along which the identical tiles of said first shape mate, deviate from straight line form.
Claim 6
Dependent Claim
25 words
A set of tiles according to claim 1 wherein the identical lines, along which said identical tiles of said first shape mate, are straight lines.
Claim 7
Dependent Claim
32 words
A set of tiles according to claim 1 wherein said identical lines, along which said tiles of said first shape mate, comprise complimentary interlocking edges of adjacent tiles of said first shape.
Claim 8
Dependent Claim
26 words
A set of tiles according to claim 1 wherein said tiles of said first shape are flat and said tiles of said second shape are flat.
Claim 9
Dependent Claim
17 words
A set of tiles according to claim 1 wherein said tiles of each shape have surface markings.
Claim 10
Dependent Claim
22 words
A set of tiles according to claim 1 wherein said tiles have edge markings to indicate a prescribed matching with juxtaposed tiles.
Claim 11
Dependent Claim
83 words
A set of tiles according to claim 1 further comprising at least one foreign tile different from the tiles of said first shape and different from the tiles of said second shape said foreign tile having a contour to mate with at least said tiles of said first shape juxtaposed with respect to said foreign tile, the total number of foreign tiles in said greater assemblage being substantially less than the total number of tiles of said first shape and said second shape.
Claim 12
Dependent Claim
28 words
A set of tiles according to claim 1 wherein each tile of each shape has the area of quadrilateral with angles which are an integer multiple of 36°.
