Patent ID: 8201377

Claim:
A flooring system or reproducing a flooring design having a periodic pattern, said flooring system comprising: a plurality of substantially similar flooring planks wherein said flooring planks are substantially rectangular and have at least a portion of said flooring design thereon; wherein the length of said planks is approximately equal to the period of said pattern; wherein the width of said planks is approximately equal to one half the height of said pattern; a first alignment pattern n a first edge and a second edge of said planks, said first and second edges being opposite each other; and a second alignment pattern on a third edge and a fourth edge of said of said planks, wherein said second alignment pattern on said third edge is offset in a horizontal direction from said second alignment pattern on said fourth edge by a distance approximately equal to one half the length of the planks, a third alignment pattern on the third edge and on the fourth edge of said planks, wherein said third alignment pattern on said third edge is offset in a horizontal direction from said third alignment pattern on said fourth edge by a distance approximately equal to one half the length of the planks, wherein the second and the third alignment patterns are different from each other, wherein said flooring design having a periodic pattern can be reproduced by laying identical planks adjacent to each other in a horizontal direction, such that said first alignment patterns of adjacent planks are placed adjacent to each other, and by laying identical planks adjacent to each other in a vertical direction offset horizontally such that said second alignment patterns of adjacent planks are placed adjacent to each other.
