Abstract
Abstract A flooring system including a plurality of flooring boards, each comprising an upper wearing surface, a bottom surface, and longitudinally extending sides. The boards are located in sideby-side relationship on a support with clips having engaging fingers securing the boards on the support. Each side of the boards defines a surface portion extending angularly downwardly, horizontally and then downwardly to provide a mating configuration with an adjacent board. A groove is formed in one side of the board, and this groove is adapted to receive a finger of a securing clip. The horizontally extending surfaces are located substantially below center, and the groove is located beneath the horizontal surfaces whereby a maximum wearing depth can be provided with a minimum of board thickness.

431 words
In a flooring system comprising a plurality of flooring boards each comprising an upper wearing surface, a bottom surface, and longitudinally extending sides comprising a first side and a second side, said boards being located in side-by-side relationship on a support with clips having engaging fingers for securing the boards to the support, the improvement wherein the first side of each board defines a first surface portion extending downwardly from said wearing surface and tapering inwardly away from the vertical and toward the center of the board, a second horizontal surface portion extending from its intersection with said first surface portion outwardly away from the center of the board, and a third surface portion extending downwardly from the outer edge of said second surface portion and tapering inwardly away from the vertical and toward the center of the board to said bottom surface, the combination of said second and third surfaces defining a tongue on said board, the second side of each board comprising a first surface portion extending downwardly from sAid wearing surface and tapering outwardly away from the vertical and away from the center of the board, a second horizontal surface portion extending from its intersection with said first surface portion inwardly toward the center of the board, and a third surface portion extending downwardly from the inner edge of said second surface portion and tapering outwardly away from the vertical and away from the center of the board to said bottom surface, the second and third surfaces of said second side defining a recess for receiving said tongue, the surface portion of said first side comprising uninterrupted surfaces, and a groove extending along the second side only of the board for receiving clip fingers, said groove extending inwardly of the board as a continuation of the second surface on said second side, said clip fingers extending horizontally, the body portion of each clip comprising an angularly extending portion conforming to the third surface portion of said second side whereby this angularly extending portion of each clip snugly engages said third surface of said second side and is snugly engaged by the third surface portion on the first side of the adjacent board, the first, second and third surface portions of said first side mating, respectively, with the first, second and third surface portions of the second side of an adjacent board in said system, the intersections between each of the first and second surface portions being located substantially below center in said boards whereby the wearing depth of the flooring boards is greater than one-half the board thickness.
