OVERHEAD GARAGE DOOR OPENING SYSTEM
Overhead door opening system that includes one or more torsion bars that twist when the overhead doors are moved from an open to a closed position manually or by an automatic opener having a motor so as to store potential energy in the torsion bars. Potential energy stored up in the torsion bars is released when the overhead doors are raised manually or by the automatic opener so that the released energy assists in lifting the overhead doors. The overhead door opening systems of the present invention do not require torsion springs that can fail over time.
