PCT No. PCT/US98/15414 Sec. 371 Date Sep. 14, 1998 Sec. 102(e) Date Sep. 14, 1998 PCT Filed Jul. 24, 1998 PCT Pub. No. WO99/05384 PCT Pub. Date Feb. 4, 1999A rigid-panel overhead door which is selectively moved up and down to open and close an opening and which is guided generally along door guides on opposed vertical sides of the opening is disclosed. The door includes a first chain disposed along one of the door guides and a second chain disposed along an opposed door guide. The door further includes a plurality of panels, each having a first end and a second end, the panels being of sufficient length to extend substantially across the opening but sufficiently limited in length so as to fit between the first and second chains and not extend beyond them. The door further includes a plurality of connectors for joining the first and second chains respectively to the first and second ends of each of the panels. Also disclosed is a rigid-panel overhead door including a door guide having a first portion which guides the door body vertically, a second portion which guides the door body horizontally, and a third portion which directs the door body into a coiled position for storage when the door is in an overhead position. The door also has a motor operatively connected to the door to move the door body along the door guide to open and close the door. The motor is situated so that a space between the first and third door guide portion is provided. The space is of sufficient size to accommodate locating at least the motor so that the door body does not obstruct access to the motor from at least one direction when the door body is accumulated into an overhead position. A method of making a hinge for use in an interlinked hinge chain for guiding and moving a door between an open and a closed position is also disclosed. The method comprising the steps of (1) defining a desired hinge thickness, height and profile as viewed from a cross section through a thickness of the hinge; (2) providing an extrusion mold which will extrude elongated stock having the desired thickness, height and profile; and (3)cutting or otherwise dividing the extruded length into the desired width for the hinge. |
