Abstract
Mechanical fasteners having parallel barbs extending vertically from a horizontal planar member to secure layers of a floor covering. When interposed between floor covering layers the barbs penetrate and anchor into a floor covering material. When a consumer desires to separate the layers, and to replace or recycle one or all the layers of the floor covering, he can do so readily by pulling the layers apart, and then securing new layers together with the mechanical fastener.
