ABSTRACT:
A spring system for stabilizing bifolding door hinged positions includes an integral "C"-shaped spring with at each end of the "C"-shape a respective straight shank formed at right angles to the plane of the "C"-shape in parallel spacing from each other. On each shank is a rotatable tubular sleeve bearing with a collar-shaped enlargement at the end adjacent the "C"-shape, and a retainer on the free end of each shank that keeps the tubular sleeve bearings in place. Installation is by insertion of the tubular sleeve bearings in parallel-spaced drilled holes in the top edges of two doors that are hinged together so that the spring assembly substantially bridges the hinges and biases the faces of the doors together to keep them in the open position, and biases the edges of the doors together to keep them in the closed position.
