ABSTRACT:
A system for reinserting a dislodged roller of a movable overhead door and a bracket for accomplishing this result. A reinsertion bracket is positioned along both the vertical and horizontal portion of each side of a door track. The reinsertion bracket consists of a base plate and a pair of guide plates connected to the base plate at an acute angle. When a roller becomes dislodged from the wheel track, the forward or reverse movement of the overhead door will cause the roller and shaft to contact one of the guide plates of the reinsertion bracket. The guide plate contains a roller guide surface which directs the disengaged roller upward and inward until it is reinserted into the door track through a removed portion of the retaining ridge of the door track. The reinsertion bracket is resiliently mounted to the door track such that when a dislodged roller contacts the guide plate, the reinsertion bracket can flex to reinsert the roller within the door track.
