Abstract
A hinge assembly that includes a closure member such as a door and a torsion bar that extends between hinge assemblies about which the door pivots so that the torsion bar becomes twisted when the door is moved between a closed position and an open position. The twisting of the torsion bar creates potential energy in the torsion which can be used to open or close the door. A force adjustment mechanism is provided which releases built-up potential energy in the torsion bar in a controlled manner so as to close open the door in a controlled manner.
