Abstract

The invention concerns a cabinet hinge with a depth adjusting device for hinge arm held directly or indirectly on a cabinet-side, single- or multi-part mounting plate. A revolvable depth adjusting screw held in the mounting plate is provided in order to adjust the depth. A driver plate is connected with the hinge arm; whereby, the depth adjusting screw has adjusting elements that work together with corresponding adjusting surfaces on the driver plate in such a way that by turning the depth adjusting screw, the driver plate and the hinge arm are moved in relation to the mounting plate. The invention offers the advantage that with only turn, the depth adjusting screw can finely and delicately adjust the depth position of the hinge arm over its entire adjustment range.

Claims

1. Cabinet hinge with a depth adjusting device a mountable on a cabinet, comprising:

a mounting plate;

a hinge arm, supported on the mounting plate;

a driver plate that is connected to the hinge arm;

a revolvable depth adjusting screw received in the mounting plate and having a longitudinal axis; and

a plurality of spaced-apart adjusting elements disposed on the adjusting screw eccentric to the longitudinal axis of the adjusting screw that cooperatively engage corresponding adjusting surfaces on the driver plate, so that by turning the depth adjusting screw, the driver plate and the hinge arm are shifted in relation to the mounting plate.

2. Cabinet hinge according to claim 1, wherein the driver plate is formed in a substantially U-shaped cross-section and has an upper and a lower driver shank that are connected together at a side edge, each driver shank having an opposite side edge that is free.

3. Cabinet hinge according to claim 2, wherein the corresponding adjusting surfaces on the driver plate are formed on the free side edge of each driver shank and wherein each corresponding adjusting surface further comprises a driver slot, an adjoining merging rolling surface, and a stop bay;

whereby, the driver slots and stop bays of the respective driver shanks are located opposite each other.

4. Cabinet hinge, according to claim 3, wherein the adjusting elements of the adjusting screw further comprise two crank pins, each having a central axis and located at opposite sides of a concentric crank disk of the adjusting screw, the crank disk also having a central axis, that are placed about 180°

to each other and whose central axes run parallel to the central axis of the crank disk, so that the central axes of the crank pins are parallel to one another.

5. Cabinet hinge, according to claim 4, wherein the two crank pins further comprise an upper crank pin engaging the adjusting surface of the upper driver shank and a lower crank pin engaging the adjusting surface of the lower driver shank;

whereby when one of the crank pins engages in the driver slot of one of the adjusting surfaces, the other crank pin lies on one of the running surface and the stop bay of the other of the adjusting surfaces.

6. Cabinet hinge, according to claim 5, wherein the crank disk of the adjusting screw is received in a bore hole formed in the adjusting plate.

7. Cabinet hinge, according to claim 6, wherein the driver plate is held movable on the adjusting plate;

whereby, the crank disk of the adjusting screw and portions of the adjusting plate adjacent the bore hole formed in the adjusting plate are located in a gap defined between the driver shanks of the driver plate.

8. Cabinet hinge, according to claim 7, wherein the upper driver shank of the driver plate has upward projecting brackets that engage in corresponding recesses formed in the hinge arm.

9. Cabinet hinge, according to claim 8, wherein a single revolution of the revolvable depth adjusting screw corresponds to over 360°

of a maximum shift of the driver plate and the hinge arm in relation to the mounting plate.
