Abstract

A furniture hinge includes a fitting part and a hinge cup that is pivotably connected thereto by way of at least one articulated lever. The articulated lever is connected to the hinge cup by way of an articulated axis (A). A cushioning apparatus can be actuated by an actuating element and is provided to cushion a relative movement between the fitting part and the hinge cup. The actuating element is mounted inside the hinge cup rotatably about a rotational axis (S) extending substantially parallel to the articulated axis (A) of the hinge cup, and the cushioning apparatus includes at least one linear cushioning member having at least one linearly displaceable plunger. A transmission mechanism converts a rotary movement of the actuating element into a linear movement of the plunger of the linear cushioning member.

Claims

1. A furniture hinge comprising:

a fitment portion;

a hinge lever;

a hinge cup pivotally connected to said fitment portion by said hinge lever, said hinge lever being connected to said hinge cup by a hinge axis;

a damping device comprising a linear damper arranged at an outside surface of said hinge cup, and said linear damper including a linearly displaceable piston;

an actuating element configured to actuate said damping device so as to dampen a relative movement between said fitment portion and said hinge cup, said actuating element being entirely and continuously arranged within said hinge cup, said actuating element being pivotally mounted so as to be rotatable about an axis of rotation extending substantially parallel to said hinge axis of said hinge cup;

a transmission mechanism configured to convert a rotary movement of said actuating element into a linear movement of said piston of said linear damper; and

a housing, said linear damper being arranged within said housing, said housing being fitted onto an outer surface of said hinge cup so as to be insertable jointly with said hinge cup within a cylindrical bore in a furniture part.

2. The furniture hinge of claim 1, wherein said hinge cup has at least one laterally projecting fixing flange, said damping device being arranged adjacent to a furniture-facing surface of said fixing flange and at said outside surface of said hinge cup.

3. The furniture hinge of claim 1, wherein said linear damper further includes a fluid chamber, said piston being guided displaceably in said fluid chamber.

4. The furniture hinge of claim 1, wherein a direction of linear movement of said piston is substantially perpendicular to said hinge axis.

5. The furniture hinge of claim 1, wherein said linear damper comprises a fluid damper.

6. The furniture hinge of claim 1, wherein said actuating element is configured and arranged to be acted upon during a hinge movement by one of said fitment portion and said hinge lever.

7. The furniture hinge of claim 1, wherein, at least during a damping stroke of said damping device, said actuating element is operatively connected to said piston of said linear damper.

8. The furniture hinge of claim 1, wherein said actuating element is motionally continuously coupled to said piston of said linear damper by said transmission mechanism.

9. The furniture hinge of claim 1, wherein a side wall of said hinge cup has an opening, said transmission mechanism arranged so as to extend from an inside of said hinge cup through said opening to an outside of said hinge cup.

10. The furniture hinge of claim 1, wherein said transmission mechanism has a lever hingedly connected to said actuating element and connected to said piston of said linear damper.

11. The furniture hinge of claim 10, wherein said lever is connected to a piston rod of said piston.

12. The furniture hinge of claim 11, wherein said piston rod has a bent shape so as to extend through an opening of said hinge cup from an inside of said hinge cup to an outside of said hinge cup.

13. The furniture hinge of claim 1, wherein said piston of said linear damper has a piston rod, said piston and said piston rod have a one-piece construction.

14. The furniture hinge of claim 1, wherein said hinge cup has an outer flat surface, said damping device being arranged at said outer flat surface of said hinge cup.

15. The furniture hinge of claim 1, wherein said hinge cup has oppositely-located side walls, each of said side walls having an outer flat surface, said linear damper of said damping device comprising a first linear damper located at said outer flat surface of a first one of said side walls, said damping device further comprising a second linear damper located at said outer flat surface of a second one of said side walls.

16. The furniture hinge of claim 1, wherein said housing has an arc-shaped outer surface, said linear damper being arranged within said arc-shaped housing, said arc-shaped housing being fitted around an outer surface of said hinge cup so as to be insertable jointly with said hinge cup within the bore of the furniture part.

17. The furniture hinge of claim 1, wherein said linear damper has a first fluid chamber and a second fluid chamber each filled with damping fluid and connected together by a passage so as to communicate with each other.

18. The furniture hinge of claim 17, wherein said piston is movably mounted within said first fluid chamber so as to change a volume of said first fluid chamber when moving, said linear damper further including a volume-changing device within said second fluid chamber, said device being deformable or movable by a flow of said damping fluid into or out of said second fluid chamber so as to change a volume of said second fluid chamber.

19. The furniture hinge of claim 18, wherein said volume-changing device comprises one of a deformable material portion and a displaceable piston.

20. The furniture hinge of claim 1, wherein said piston of said linear damper comprises a first piston, said linear damper further including a second piston having a linear damping stroke, a direction of a linear damping stroke of said first piston extending substantially parallel relative to said linear damping stroke of said second piston.

21. The furniture hinge of claim 1, wherein said transmission mechanism includes a rotatably mounted lever motionally coupled to said actuating element.

22. The furniture hinge of claim 21, wherein said piston of said linear damper is movable by said lever.

23. The furniture hinge of claim 21, wherein said piston of said linear damper comprises a first piston, said linear damper further including a second piston, said lever comprises a double-armed lever having a first lever arm cooperating with said first piston and a second lever arm cooperating with said second piston.

24. An article of furniture comprising:

a furniture body;

a movable furniture part; and

a furniture hinge for movably mounting said movable furniture part to said furniture body, said furniture hinge including;

a fitment portion;

a hinge lever;

a hinge cup pivotally connected to said fitment portion by said hinge lever, said hinge lever being connected to said hinge cup by a hinge axis;

a damping device comprising a linear damper arranged at an outside surface of said hinge cup, and said linear damper including a linearly displaceable piston;

an actuating element configured to actuate said damping device so as to dampen a relative movement between said fitment portion and said hinge cup, said actuating element being entirely and continuously arranged within said hinge cup, said actuating element being pivotally mounted so as to be rotatable about an axis of rotation extending substantially parallel to said hinge axis of said hinge cup;

a transmission mechanism configured to convert a rotary movement of said actuating element into a linear movement of said piston of said linear damper; and

a housing, said linear damper being arranged within said housing, said housing being fitted onto an outer surface of said hinge cup so as to be insertable jointly with said hinge cup within a cylindrical bore formed in one of said furniture body and said movable furniture part.
