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. A damping device for a furniture door, comprising

a damper housing comprising a recess,

a damping cylinder longitudinally displaceably mounted relative to the recess, the damping cylinder comprising a cylinder housing displaceably mounted in a hole of the recess and a piston rod, a portion of the cylinder housing at a first end of the damping cylinder protruding out of a front end of the recess and forming a stop fur the furniture door, and

an adjusting screw, the damping cylinder being longitudinally adjustable relative to the damper housing by the adjusting screw, the adjusting screw having external threads that mate with internal threads of the recess so that the adjusting screw is movably attached on a back end of the recess,

wherein the piston rod is connected to the adjusting screw and an inner diameter of the internal threads of the recess is at least as large as an inner diameter of the hole in which the cylinder housing is mounted.

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

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

4. The 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, the centric hole being a blind hole.

5. The damping device according to claim 1, wherein the adjusting screw comprises a handle section that protrudes from the damper housing and comprises a knurling contour.

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

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

9. The damping device according to claim 7, wherein the pressure spring is compressed between the pressure body and the spring stop.

10. The damping device according to claim 7, wherein the pressure body rests against a stop of the adjusting screw when the pressure body is in a least-compressed starting position.

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

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

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

14. The damping device according to claim 6, wherein the damper housing comprises an external housing pa and an internal housing part arranged therein in a longitudinally displaceable manner, the damper housing receiving the cylinder housing in the hole in a longitudinally displaceable manner and the pressure spring being arranged between the external housing part and the internal housing part.

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