OVERHEAD SECTIONAL DOOR, HINGE AND ASSOCIATED METHOD.

摘要

An overhead door (10) and associated mating panels (14) includes a number of hinges to pivotally couple adjacent overhead door panels (14). Each door panel (14) includes a back metal skin (36) presenting a back face. Each hinge (20) includes a lower hinge leaf (50) a pair of hinge legs projecting generally parallel to each other. The lower hinge leaf (50) is mounted to the lower panel and a backer plate (56) is mounted to the interior face of the back skin (36) of the lower panel and screws or bolts project through the lower hinge leaf (50), the skin (36) and into the backer plate (56) . Each hinge leg (58) on the lower hinge leaf (50) includes a hinge pin hole near a terminal end thereof for alignment with the hinge pin holes in an upper hinge leaf (40). The lower hinge leaf (50) has a tongue (72) projecting from an upper edge (74) of the mounting base (52). The tongue is formed into a hook????shaped arcuate projection and aids in the alignment, support and positioning of a hinge pin inserted through the aligned hinge pin holes in the upper and lower hinge leaves. A depression or pocket (80) is provided in the back skin (36) of the lower panel for each hinge assembly. The pocket provides a recess for the terminal ends of the hinge legs (58) of the upper and lower hinge leaves. The shape or contour of the wells of the pocket (80) provides a location or alignment benefit to the positioning of the lower hinge leaf.
