Abstract:
1. An overhead door assembly for selectively closing and sealing an opening in a building with framing located along the sides of the opening, the overhead door assembly comprising: a multi-panel door with opposed sides and formed by a plurality of panels aligned in substantially flush registered alignment to form sets of adjacent door panels, each said panel having a length sufficient to span said opening; a dual track assembly formed by opposed tracks, each said track having a substantially vertical track portion fixed to the framing on one of said sides of the opening, said dual track assembly guiding and allowing selective movement of said door between open and closed positions, each said vertical track portion having an inner end, and said vertical track portions being spaced from said framing to create a gap between said panels and said framing when said door is in said closed position; a plurality of wheel assemblies, each assembly including a wheel and a wheel axle, each said wheel being movably and guidably held by one of said tracks, said inner end of said vertical track portions preventing said wheels from moving away from the opening when said door is in said closed position; a plurality of spring-loaded roller hinges positioned proximal said sides of said door, each spring-loaded roller hinge including pivotally joined brackets, each bracket allowing hinged movement between said adjacent door panels, one bracket of said brackets having inner and outer spaced apart flanges supporting a pivoting wheel hub, said inner flange pivotally holding a pivot end of said wheel hub, said wheel hub pivoting about a pivot point, said outer flange having an elongated slot to movingly guide a movable end of said pivoting wheel hub, each said wheel hub holding one said wheel axle, said wheel axle extending from said wheel hub toward its said track with its said wheel engaging its said track; each spring-loaded roller hinge including a biasing mechanism, said biasing mechanism engaging said pivoting wheel hub to resiliently bias its said movable end toward an outermost end of said slot; and, wherein each of said biasing mechanisms resiliently pushes its said wheel against said inner end of its said vertical track portion to resiliently push its said adjacent door panels toward the framing to close said gap and seal the door when said door is in said closed position.
