ABSTRACT:
A wall base for wall-to-wall carpeting, formed of a rubbery plastic material, has a flat planar portion for engaging against the wall and an outwardly extending bead or flange positioned to engage the surface of the carpet and to cover its edge. In a preferred embodiment the extending bead has a convexly curved upper surface and a flat lower surface, giving the bead appreciable rigidity, so that a carpet with its edge lying over the bead can easily be tucked under the bead using a blade-type tool. In one embodiment the flat lower surface can be downwardly inclined slightly, e.g. about 5.degree., so that the outer edge line of the bead engages the carpet pile in a sharp line. A tail extension of the flat planar portion extends below the bead or flange and established a proper height of the flange above the floor. The carpet wall base of the invention may be installed before installation of a carpet, and may be left in place when a carpet is removed and replaced.
