ABSTRACT:
Over-center hinge for cabinet doors, having a door-related part in the form of a recess-mounted cup in which the ends of inner and outer links are pivotingly mounted whose outer ends are pivoted on a supporting-wall-related part in the form of a supporting arm, a pressure piece biased by a spring being pivotingly mounted within the supporting arm on the inner link nearest the supporting wall and bearing against a counter-surface which during the hinge movement undergoes a change of position relative to the pressure piece such that the hinge, after passing beyond a dead center during the closing movement, is resiliently forced into the closed position. The spring is a torsion coil spring whose one arm bears against the inner link and whose other arm bears against the pressure piece, and which spring is held by a pin which is provided at a distance above the pivot eye of the inner link and which passes through the coils of the torsion coil spring, and whose ends are fastened each in a bore in each of the ears formed on and bent up from opposite longitudinal sides of the inner link. The configuration is such that the free ends of the arms of the torsion coil spring point out of the supporting arm toward the door-related hinge part.
