ABSTRACT:
Over-center hinge for furniture doors, in which one of the hinge parts has a mortise cup manufactured of plastic, from whose circumferential wall a diagonally disposed tongue which is integral with the mortise cup and can be flexed against spring bias, projects into the interior of the mortise cup, and on which, during a portion of the movement of the hinge, a contact surface provided on the other hinge part at its end facing the pivot, slides and can be moved in an intermediate position through a dead point on one side of which it urges the door to the closed position and on the other side of which it exerts a pressure in the opening direction. The contact surface is so disposed that, in the closed position, it lies in the direct vicinity of the pivot axis of the tongue. The upper end of the tongue is integrally joined by a resiliently flexible section to the mortise cup, and the bottom free end of the tongue which is originally made in an approximately parallel position with respect to the circumferential wall has two short projections projecting laterally in opposite directions. The projections are snapped into lateral recesses associated with them in the transition area from the bottom to the circumferential wall of the cup such that the tongue is bent from its originally parallel position with respect to the circumferential wall into the diagonal position and placed under bias.
