Abstract
Abstract A variable mosaic pattern formed from interfitting blocks formed into standard shape is disclosed groups with curved or serpentine shapes. Interchangeability of the groups of the standard shapes permits easy installation, and production machinery presently available permits low cost manufacturing of the interchangeable components, which can be made of a suitable plastic molded from suitably shaped molds or stamped out on presses, cut from slabs of stone, or formed by other suitable means. The interchangeable components can be assembled indefinitely in any direction in an ever-changing mosaic pattern creating a random decorative effect.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
138 words
In a surface covering comprising a plurality of interfitting blocks having substantially parallel top and bottom faces and edges interfitting with contiguous blocks, the improvement comprising blocks arrangeable into a variable mosiac pattern which forms said surface covering, the pattern being characterized by visual randomness and a random decorative effect, the blocks having arcuate edges and at least three different highly irregular shapes with no perpendicular axes of symmetry, the blocks being contiguously associable into one or more groups wherein at least one group of contiguous blocks is interchangeable with one or a plurality of other adjacent groups so as to create an appearance of visual randomnesss and avoid a recognizable appearance of repetitiveness or symmetry, the number of different highly irregular shapes being less than about 20, and each of said shapes having at least one cusp.
Claim 2
Dependent Claim
138 words
In a surface covering comprising a plurality of interfitting blocks having substantially parallel top and bottom faces and edges interfitting with contiguous blocks, the improvement comprising blocks arrangeable into a variable mosiac pattern which forms said surface covering, the pattern being characterized by visual randomness and a random decorative effect, the blocks having arcuate edges and at least three different highly irregular shapes with no perpendicular axes of symmetry, the blocks being contiguously associable into one or more groups wherein at least one group of contiguous blocks is interchangeable with one or a plurality of other adjacent groups so as to create an appearance of visual randomnesss and avoid a recognizable appearance of repetitiveness or symmetry, the number of different highly irregular shapes being less than about 20, and each of said shapes having at least one cusp.
Claim 3
Dependent Claim
18 words
The surface covering of claim 1 wherein said group of contiguous blocks is a pair of contiguous blocks.
Claim 4
Dependent Claim
22 words
The surface covering of claim 1 wherein said surface covering comprises a substantially planar interior surface of the room of a building.
Claim 5
Dependent Claim
39 words
The surface covering of claim 3 wherein said blocks are stone or plastic and have a plurality of colors, whereby even greater variety of patterns is creatable and is enhanced by the complete absence of standard repetitive geometric patterns.
Claim 6
Dependent Claim
14 words
The surface covering of claim 3 wherein said blocks are made of moldable material.
Claim 7
Dependent Claim
13 words
The surface covering of claim 1 wherein said blocks have twelve different shapes.
