Abstract:
1. An overhead door system, comprising: an overhead door having a plurality of pivotally interconnected door panels operable to move between vertical and horizontal positions relative to a door frame, each of said door panels having guide members arranged on opposite sides thereof; a support rail mounted to and extending generally horizontally from a side of said door frame; a pair of generally channel-shaped horizontal track members each defining a generally horizontal channel for guiding movement of said guide members; a pair of generally channel-shaped vertical track members mounted respectively to opposite sides of said door frame, each of said vertical track members defining a generally vertical channel for guiding movement of said guide members; a pair of generally channel-shaped radius track members extending in a defined radius of curvature to join respective ends of said vertical track members to respective ends of said horizontal track members and thereby form a pair of substantially continuous door tracks on opposite sides of said door frame, each of said radius track members defining a curved channel for guiding movement of said guide members between said horizontal and vertical channels; wherein the support rail is coupled to one of the horizontal, vertical and radius track members; a counterbalancing system coupled to the overhead door to assist in moving the door from the vertical position toward the horizontal position; a stationary sheave positioned a spaced distance from the door frame; a cable coupled to the overhead door and the counterbalancing system and routed on the stationary sheave; a slot formed in said support rail and said cable is routed through said slot; wherein said stationary sheave is positioned within said slot.
