Abstract
A panel door of composite construction includes a pair of stiles and top and bottom rails which cooperate to define a rectangular frame, a plastic foam core bordered by the frame and an opposed pair of molded fiberglass skins which sandwich the frame and core. Each skin has an edge located rim portion which overhangs the outer corner edges of the stiles and rails, and each of the stiles and rails has an outer corner edge with a profile complementary to and mating with the inside of the adjacent rim portion. Along the side edges, the skins have innermost and outermost rim portions, and the stiles have complementary profiled outer corner edges.
Claims10
A door of composite construction comprising a pair of stiles and top and bottom rails cooperating to define a rectangular frame, and a pair of opposed skins of molded reinforced resin mounted on said frame and cooperating therewith to define an enclosed interior space, and further characterized in that
- (a) each of said skins is of substantially uniform minimum thickness over the major portion of the area thereof,
- (b) each of said skins includes along each edge of the inside thereof a rim portion of greater thickness than said minimum thickness,
- (c) said rim portions of said skins include edge portions proportioned to overhang said outer corner edges of said stiles and rails and thereby to retain said stiles and rails in partially enclosed relation and also to define the corner edges of the sides and the top and bottom of said door,
- (d) each of said stiles and rails has along the outer corner edges thereof a profile complementary to and mating with the inside of the adjacent said rim portion of said skin;
- and
- (e) each said rim portion along the side edges of said skins includes both an inner portion of sufficiently greater thickness than said minimum thickness to form a shoulder and also an outermost portion of still greater thickness to form a flange extending further inwardly of said enclosed space than said shoulder, and each of said stiles has the outer corner edges thereof profiled to match and engage said shoulders and flanges.
A door as defined in claim 3 characterized in that each said rim portion along the top edge of each of said skins duplicates the configuration of said rim portion along the bottom edge of said skin as defined in claim 6, said top and bottom rails are of identical cross section and are similarly oriented in said door, and each of said rails includes a rib portion along the top thereof which is proportioned to fill the space between said outer flanges on the tops of said skins.
A door of composite construction comprising a pair of stiles and top and bottom rails cooperating to define a rectangular frame, and a pair of opposed skins of molded reinforced resin mounted on said frame and cooperating therewith to define an enclosed interior space, and further characterized in that
- (a) each of said skins is of substantially uniform minimum thickness over the major portion of the area thereof,
- (b) each of said skins includes along each edge of the inside thereof a rim portion of greater thickness that said minimum thickness,
- (c) said rim portions of said skins include edge portions proportioned to overhang said outer corner edges of said stiles and rails and thereby to retain said stiles and rails in partially enclosed relation and also to define the corner edges of the sides and the top and bottom of said door,
- (d) each of said stiles and rails has along the outer corner edges thereof a profile complementary to and mating with the inside of the adjacent said rim portion of said skin;
- and
- (e) each of said skins includes adjacent each edge thereof flange means on the inner surface thereof which is parallel with the adjacent said rim portion and is so spaced inwardly from said rim portion that it engages and retains the corner edge of the adjacent said stile or rail.
