Abstract

A furniture hinge, comprising a fitting part and a hinge cup that is pivotably connected thereto by way of at least one articulated lever, the articulated lever being connected to the hinge cup by way of an articulated axis (A), and further comprising a cushioning apparatus which 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 being 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 comprising at least one linear cushioning member having at least one linearly displaceable plunger, said member being disposed on the outside of the hinge cup, characterized in that a transmission mechanism is provided, which converts a rotary movement of the actuating element into a linear movement of the plunger of the linear cushioning member, and the hinge cup and the linear cushioning member or members disposed on the hinge cup are all disposed inside a cylindrical bore (B) in the furniture part in the installed position.

Claims

1. A furniture hinge, comprising:

a fitment portion,

a hinge cup pivotally connected to said fitment portion by way of at least one hinge lever, said hinge lever is connected to said hinge cup by way of a hinge axis,

a damping device actuable by an actuating element for damping a relative movement between said fitment portion and said hinge cup, said actuating element is mounted within said hinge cup rotatably about an axis of rotation extending substantially parallel to said hinge axis of said hinge cup,

said damping device has at least one linear damper which is arranged at the outside of said hinge cup, said damping device has at least one linearly displaceable piston,

a transmission mechanism which converts a rotary movement of said actuating element into a linear movement of said piston of said linear damper,

wherein said hinge cup and said linear damper or dampers arranged on said hinge cup are arranged in the installation position all within a cylindrical bore in a furniture part.

2. The furniture hinge according to claim 1, wherein the hinge cup has at least one laterally projecting fixing flange, wherein the damping device is arranged beneath the fixing flange and at the outside of the hinge cup.

3. The furniture hinge according to claim 1, wherein the piston of the linear damper is guided displaceably in a fluid chamber.

4. The furniture hinge according to claim 1, wherein the direction of the linear movement of the piston is substantially perpendicularly to the hinge axis of the furniture hinge.

5. The furniture hinge according to claim 1, wherein the linear damper is in the form of a fluid damper.

6. The furniture hinge according to claim 1, wherein the actuating element can be acted upon during a hinge movement by the fitment portion or by the hinge lever of the furniture hinge.

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

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

9. The furniture hinge according to claim 1, wherein a side wall of the hinge cup has an opening, wherein the transmission mechanism extends from the inside of the hinge cup through the opening to the outside of the hinge cup.

10. The furniture hinge according to claim 1, wherein the transmission mechanism has at least one lever which is hingedly connected to the actuating element and which is connected or can be coupled to the piston of the linear damper.

11. The furniture hinge according to claim 10, wherein the lever is connected or can be coupled to a piston rod of the piston, the piston rod being part of the transmission mechanism.

12. The furniture hinge according to claim 11, wherein the piston rod is of a cranked shape, wherein by virtue of the cranked shape the piston rod extends through an opening of the hinge cup from the inside of the hinge cup to the outside thereof.

13. The furniture hinge according to claim 1, wherein the piston of the linear damper has a piston rod, wherein the piston and the piston rod are of a one-piece construction.

14. The furniture hinge according to claim 1, wherein the outside of the hinge cup has at least one flat surface at which the damping device is arranged.

15. The furniture hinge according to claim 1, wherein the hinge cup has oppositely disposed side walls, wherein the side walls at their outside each have a respective flat surface provided for the arrangement of separate damping devices.

16. The furniture hinge according to claim 1, wherein at its outside the hinge cup has a respective damping device, wherein the hinge cup together with the damping devices arranged thereon can be inserted jointly within the provided bore and is arranged within a notional bore diameter of the bore.

17. The furniture hinge according to claim 1, wherein the damping device has first and second fluid chambers filled with damping fluid and connected together by a passage.

18. The furniture hinge according to claim 17, wherein a piston is immersed in the first fluid chamber, by which piston the volume of the first fluid chamber can be changed, and wherein arranged in the second fluid chamber is a device which is deformable or movable by a flow of damping fluid into or out of the second fluid chamber, to change the volume of the second fluid chamber.

19. The furniture hinge according to claim 18, wherein the device has a deformable material portion arranged in the second fluid chamber or a piston displaceable in the second fluid chamber.

20. The furniture hinge according to claim 1, wherein the damping device has a first piston and at least one second piston with a linear damping stroke, the direction of the linear damping stroke of the first piston extending substantially parallel relative to the linear damping stroke of the second piston.

21. The furniture hinge according to claim 1, wherein the transmission mechanism has at least one rotatably mounted lever which is motionally coupled to the pivotally mounted actuating element.

22. The furniture hinge according to claim 21, wherein at least one piston is movable by the lever.

23. The furniture hinge according to claim 21, wherein the lever is in the form of a double-armed lever, wherein a first lever arm cooperates with the first piston of the damping device and a second lever arm cooperates with a second piston of the damping device.

24. An article of furniture having at least one movable furniture part which is mounted movably by way of at least one furniture hinge according to claim 1.
