Abstract

A damping device for furniture doors includes a damping cylinder longitudinally displaceably mounted in a recess of a damper housing including a cylinder housing and a piston rod and forming a stop for the furniture door. The cylinder housing is longitudinally displaceably mounted in the recess of the damper housing, the recess being formed as a hole, the end thereof protruding out of the damper housing forming a stop for the furniture door. The adjusting screw forms an axial counterbearing for the piston rod. The inner diameter of an internal thread receiving the adjusting screw is at least equal to the inner diameter of the hole receiving the cylinder housing. The end of the piston rod is received in a centric hole of the adjusting screw

Claims

1. Damping device for furniture doors comprising a damping cylinder longitudinally displaceable mounted in a recess of a damper housing, comprising a cylinder housing and a piston rod and forming a stop for the furniture door can be longitudinally adjusted by means of an adjusting screw on the back end of the recess facing away from the stop, wherein the cylinder housing is mounted in a longitudinally displaceable manner in the recess of the damper housing, said recess being formed as a hole, the end thereof protruding out of the damper housing forming a stop for the furniture door, in that the piston rod is connected to the adjusting screw and in that the inner diameter of an internal thread receiving the adjusting screw is at least equal to the inner diameter of the hole receiving the cylinder housing.

2. Damping device according to claim 1 wherein the end of the piston rod is received in a centric hole of the adjusting screw.

3. Damping device according to claim 2 wherein the end of the piston rod is pressed into the centric hole of the adjusting screw.

4. Damping device according to claim 2 wherein the end of the piston rod is received in a longitudinally displaceable manner in the centric hole of the adjusting screw, said centric hole being a blind hole.

5. Damping device according to claim 1 wherein the adjusting screw comprises a handle section that protrudes from the damper housing and comprises a knurling or a similar contour.

6. Damping device according to claim 1 wherein a pressure spring is arranged between the piston rod and the damper housing.

7. Damping device according to claim 6 wherein the pressure spring is arranged in an internal hole of the adjusting screw between a pressure body that is fixed to the piston rod and is longitudinally displaceable in the internal hole, and a spring stop fixed in the adjusting screw.

8. Damping device according to claim 7 wherein the pressure body is supported against a snap ring that is received in a peripheral groove of the piston rod.

9. Damping device according to claim 7 wherein the pressure spring is pre-stressed between the pressure body and the spring stop.

10. Damping device according to claim 7 wherein the pressure body rests against a stop of the adjusting screw when it is in its starting position.

11. Damping device according to claim 7 wherein the piston rod protrudes from an end hole of the adjusting screw on the end of the adjusting screw facing away from the damping cylinder and comprises a radial retaining projection.

12. Damping device according to claim 8 wherein the piston rod ends in the pressure body and in that the pressure body comprises a centric sliding journal on its side that faces away from the damping cylinder, said sliding journal protruding from an end hole of the adjusting screw and having a radial retaining projection.

13. Damping device according to claim 11 wherein the retaining projection is a snap ring received in a peripheral groove of the piston rod.

14. Damping device according to claim 6 wherein the damper housing is comprised of an external housing part and an internal housing part arranged therein in a longitudinally displaceable manner, receiving the cylinder housing in its hole in a longitudinally displaceable manner and in that the pressure spring is arranged between the external housing part and the internal housing part.

15. Damping device according to claim 14 wherein the pressure spring surrounds the internal housing part in a concentric manner.
