Patent

CA 2230342

A roll-up sectional door for trucks, trailers, or garages, comprising a series of panels connected by hinges allowing pivoting between the panels, wherein both the hinges and panels are suitable for injection molding. Each hinge includes a male hinge member having an integral pintle connected to its hinge leaf by a web member having a series of slots, and a female hinge member having a series of spaced knuckles dimensioned to partially embrace the pintle and to slide within the slots as the pintle rotates within the knuckles. The hinge members can be assembled when unattached to the panels, but are prevented from separation after attachment. One panel edge also has a cylindrically curved knuckle which embraces a side of the pintle opposite the spaced hinge knuckles when the parts are assembled, so that the pintle is positively held between the knuckles.
