An over-center hinge for cabinet doors, having two links in the manner of a quadruple joint, hinged at one end to a door member and at the other end to a wall member in the form of an elongated bearing arm, the links being movable through a dead-center position in the movement from the closed position to the open position, on the first side of which it is urged by the tension of a resilient element in the closing direction, and beyond which it is urged by the tension of the resilient element in the opening direction. The resilient element is disposed in the front, door-end portion of the bearing arm engaging with one end a projection at the bearing arm end of one of the links, which projection forms with the pivot axis of this link at the bearing arm end a lever arm which is so directed away from the pivot axis that it is biased by the resilient element in the hinge-closed position to a movement in the closing direction, and in the hinge-open position to a movement in the opening direction. The projection is provided on the outer link more remote from the bearing wall, and the resilient element has at least one helical spring constructed as a compression spring which is disposed under bias in the hollow interior of a thimble which is displaceable in an upper opening of the bearing arm with its open end facing the cabinet interior, and which at its extremity at the open end of the thimble engages the bearing arm. |
