  • Patent number: 4894884
    Abstract: Over-center self-closing hinge for cabinet doors, having an inner link and an outer link in a quadrilateral arrangement and a lever in the form of a hairpin spring fulcrumed at one end in the cabinet-wall-related hinge part and thrusting at right angles to the hinge axis against a cam which is journaled on the inner link and abuts in its one position against the pivot eye of the latter and in its other position against the link itself. The cam is of such a configuration that, when the hinge is moved from the open position to the closed position, just before it reaches the closed position, the line of thrust applied by the hairpin spring passes through the pivot axis of the link, but then the spring passes over onto a portion of the cam associated with the second position of the latter, thereby causing the cam to rock over and alter the line of thrust of the spring such that it seeks to close the hinge.
