  • Self-closing hinge structure
    Patent number: 4761853
    Abstract: A geared hinge is formed by a pair of intermeshed geared hinge members which are maintained in mesh by a connector member. When the hinge members are in one position there are longitudinal recesses which are diminished in volume when the hinge members are in an alternate position. Deposits of resilient rubber-like material are inserted into the open recesses. These deposits are compressed when the hinge members are moved toward the alternate position. The resistance to compression imparts a self-closing action to the hinge.
