Abstract:
A sectional door comprising: a series of panels having adjacent edges, including a first panel edge of one panel and a second panel edge of an adjacent, identical panel, connected by at least one hinge which allows relative pivoting between the panels, wherein the at least one hinge means comprises,a male hinge member having a hinge leaf mountable to a first panel edge and having an integral pintle connected to its hinge leaf by a web member having a series of slots; anda female hinge member having a hinge leaf mountable to a second panel edge and having a series of spaced knuckles of cylindrically curved shape and dimensioned to partially embrace said integral pintle and to move slidably within said slots as the pintle rotates within said knuckles;said arrangement of pintle and knuckles being such as to allow the hinge members to be assembled together when the hinge members are unattached to said edges and are pivoted within a first range of orientations relative to each other, and being such as to prevent separation of members when the hinge members are within a second range of orientations relative to each other;and wherein said second panel edge also has a cylindrically curved knuckle which embraces a side of said pintle opposite that embraced by the said spaced knuckles when said second panel edge is attached to said female hinge member, so that the pintle is held between said spaced knuckles of said female hinge member and said curved knuckle of said second panel edge.
