Patent ID: 7168146

Claim:
A process of making a hinged access hatch comprising: selecting a metal hinge having a pair of leaves rotatable on a common hinged pin, each leaf having a plurality of openings therein; placing the portion of one said leaf of said selected hinge with the plurality of openings therein in an access hatch door mold; sealing a portion of said one hinge leaf with a pair of mold seals to prevent plastic in said mold from contacting the moving portion of said hinge; molding an access hatch door in said access hatch door mold having said portion of said one leaf of said hinge having a plurality of openings molded by injecting plastic therein to thereby embed the plastic through said openings; and removably attaching said molded access hatch door to an access hatch frame by attaching fasteners through said plurality of openings in said other hinge leaf; whereby the access hatch eliminates the need for hinge door fasteners while improving the strength of said access hatch door attachment to said access hatch frame.
