Abstract:

A fully interlocking roof shingle for installing a weather-proof roof on a building. The shingles are constructed of multiple layers to expose various interlocking grooves for connection to the contiguous shingle. The interlocking grooves have a dovetail configuration to ensure secure connection of the shingles to form a substantially integral roofing system. The individual shingles include a bottom plate with a plurality of grooves disposed upwardly and a top plate with a plurality of grooves disposed downwardly. The grooves of each plate mate to form the assembled roofing shingle exposing a decorative top surface and a base surface of the upper and lower plates respectively. The plates are assembled in an offset manner so as to expose upwardly disposed grooves along two edges and downwardly disposed grooves along the other two edges. As a result, the shingles may be assembled on the roof by interlocking the grooves of the shingles. Apertures for nailing the shingle to the roof are also formed in the shingle.

Abstract:

A method of manufacturing components such as vehicle wheels which include a polystyrene base molded in the general configuration of the ornamental face and a plastic coating molded to the base and mechanically secured thereto to prevent separation. The plastic overlay is moded to the base through a low-pressure injection molding process in order to maintain the integrity of the molded base. The plastic coating flows around portions of the base to provide secure attachment between the base and overlay. The method may be used to manufacture various automotive components including vehicle wheel covers, dams and spoilers.
