Abstract
Abstract A snap-together flooring system which fixes adjacent flooring members from lateral movement with respect to one another. A first flooring member includes a channel having a downwardly extending barb. A second flooring member includes an outwardly extending tongue having a groove defined therein. The first and second flooring members are snapped together by moving the tongue into the channel, which causes the barb to ride upwardly on an inclined face of the tongue in an elastic manner, and to ultimately snap downwardly into place within the groove of the tongue. The engagement of the barb in the groove of the tongue prevents laterally removal of the tongue from the channel, and thus holds the adjacent flooring members together. Disengagement of the flooring members is provided by lifting of the interface between the adjacent flooring members and rotating the flooring member having the tongue downwardly in order to disengage the barb from the groove of the tongue, and to thus allow extraction of the tongue from the channel.
