1. A roller hinge assembly for connecting articulating door panels and simultaneously supporting a laterally extending combination door panel support axle and roller, comprising in combination:
a first hinge unit and an adjacent, side by side, uniformly sized second hinge unit, each hinge unit including a male hinge strap and a female hinge strap, each strap including a generally planar base, a front base edge, a back base edge and spaced, parallel, transverse support arms located between said front base edge and said back base edge and extending upwardly from said base, said male strap and said female strap support arms of each unit comprising two pairs of strap support arms, each pair including axially aligned hinge pintle openings, said pintle openings of the first and second units having a single pintle axis passage for receipt of a single pintle, a pair of support arms of said first hinge unit adjacent and side by side to a pair of support arms of said second hinge unit to hinge said first and second hinge units for rotation about said pintle axis, one of said female strap support arms and said male strap support arms of said hinged first and second hinged units including axially aligned roller axle bushing openings having a single roller axle bushing axis passage for receipt of a single roller axle bushing, said male and female strap hinge pintle axis of said first and second hinge units aligned parallel to the roller axle bushing axis of said axle bushing openings of said first and second hinge units, each said base including fastener openings for attachment of the hinge units to separate, adjacent door panels; a single pintle extending through the aligned pintle openings of said first and second hinge units, said single pintle having opposite outer ends which are crimped and fixed respectively to support arms of said first and second units thereby maintaining said first and second adjacent units joined together in axial, adjacent alignment whereby said hinge units are pivotal about the single pintle axis; a single, generally tubular, roller axle bushing comprising a tube extending through said roller axle bushing openings and having opposite outer ends which are crimped and fixed respectively to the axially aligned roller axle bushing openings of said first and second hinge units; and a single roller support axle and roller combination, said roller axle axially positioned in said tube formed by said single roller axle bushing, said roller axle bushing tube and roller axle having a roller axle axis parallel to said bushing axis, and said pintle axis, said pintle and axle, in combination, maintaining said units in uniform parallel axis, adjacent, abutting alignment and as a single roller hinge assembly adapted to maintaining the units conjoined as a composite hinge assembly wherein the hinge straps maintain uniform alignment and movement coincident with said roller supported adjacent one of said hinge units for engagement in a roller track. |
