Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
A plurality of identically shaped tiles for covering a plane surface in a periodic or non-periodic manner, each said tile comprising: (a) a polygon having a plurality of sides of equal length, the number of sides (S) being determined from the equation, S=2n+1; where n is an integer greater than 1; (b) the angle (A) in degrees formed between a reference side and a first side being determined by, A=120-60/n; (c) the angle (B) formed between said reference side and a second side being equal to 60 degrees; (d) each of the angles (C) in degrees formed between said first side and successive sides being adjacent thereto being determined by, C=180-60/n; (e) the angles (D) in degrees formed between said second side and successive slide being adjacent thereto being determined by, D=180+60/n; and (f) the closing angle (E) in degrees between the last successive first and second sides being given by, E=60n.

Claim 3
Dependent Claim
173 words
A plurality of identically shaped tiles for covering a plane surface in a periodic or non-periodic manner, each said tile comprising: (a) a polygon having a plurality of sides of equal length, the number of sides (S) being determined from the equation, S=2n+1, where n is an integer greater than 1, said polygon including one equilateral triangle and at least one diamond juxtaposed along one edge of said triangle, additional diamonds being juxtaposed along the opposite edge of said preceding diamond, the acute angle of one of said diamonds being adjacent the obtuse angle of the other of said diamonds, the sides of each said diamond being equal to each other and to the sides of said equilateral triangle; (b) the number of diamonds (N) being given by the equation, N=n-1; (c) the acute angle (a m ) in degrees for diamond (d m ) being given by the equation, a m =60(1-m/n); and (d) the acute angle (a n-1 ) in degrees of the Nth diamond being given by, a n-1 =60/n.
Claim 4
Dependent Claim
173 words
A plurality of identically shaped tiles for covering a plane surface in a periodic or non-periodic manner, each said tile comprising: (a) a polygon having a plurality of sides of equal length, the number of sides (S) being determined from the equation, S=2n+1, where n is an integer greater than 1, said polygon including one equilateral triangle and at least one diamond juxtaposed along one edge of said triangle, additional diamonds being juxtaposed along the opposite edge of said preceding diamond, the acute angle of one of said diamonds being adjacent the obtuse angle of the other of said diamonds, the sides of each said diamond being equal to each other and to the sides of said equilateral triangle; (b) the number of diamonds (N) being given by the equation, N=n-1; (c) the acute angle (a m ) in degrees for diamond (d m ) being given by the equation, a m =60(1-m/n); and (d) the acute angle (a n-1 ) in degrees of the Nth diamond being given by, a n-1 =60/n.
Claim 5
Dependent Claim
26 words
A plurality of identically shaped tiles according to claim 1 or 2 wherein each said tile has indicia thereon for forming a periodic or non-periodic design.
Claim 6
Dependent Claim
43 words
A plurality of identically shaped tiles according to claim 1 or 2 wherein one or more of said sides are modified from a straight line and made to be symmetrical through a rotation of 180 degrees about the central axis of said side.
Claim 7
Dependent Claim

Claim 9
Dependent Claim
52 words
A plurality of identically shaped tiles according to claim 4 wherein said tile sides are modified and a predetermined number of said tiles include indicia thereon to suggest a fish and a predetermined number of said tiles suggest a fowl, said fish and fowl tiles being integrated to cover said plane surface.
Claim 10
Dependent Claim
29 words
A plurality of identically shaped tiles according to claim 1 or 2 wherein one or more of said tiles may be turned over and integrated into said surface covering.
