Abstract

The invention relates to a multi-link hinge for furniture, with a fastening element which can be secured indirectly or directly to a furniture body and is connected to a pivotable door bearing via a plurality of link levers connected to one another in a scissors-like manner, wherein a linear damper which damps both a closing movement and an opening movement of the door bearing is provided. The multi-link hinge is distinguished in that the linear damper is ineffective in a central portion of the pivoting range of the door bearing.

Claims

1. A multi-link hinge for a piece of furniture, comprising:

a fastening element configured to be secured indirectly or directly to a furniture body and which is connected to a pivotable door bearing via a plurality of link levers that are connected to one another in a scissors configuration,

an L-shaped lever pivotable about a shaft on the fastening element;

a first one of the plurality of link levers comprising a first driver;

a second one of the plurality of link levers comprising a second driver; and

a linear damper connected to the L-shaped lever;

wherein during a closing movement, the first driver engages the L-shaped lever which actuates the linear damper for dampening the closing movement,

wherein during an opening movement, the second driver engages the L-shaped lever which actuates the linear damper for dampening the opening movement,

and wherein the linear damper is ineffective in a central portion of the pivoting range of the door bearing.

2. A multi-link hinge according to claim 1, wherein the first driver and the second driver are in engagement with the L-shaped lever only outside of the central non-dampened portion of the pivoting range.

3. A multi-link hinge according to claim 1, wherein at least one of the first and second drivers is formed integrally on the respective one of the first and second link lever.

4. A multi-link hinge according to claim 1, wherein at least one of the first and second drivers is arranged as a control cam.

5. A multi-link hinge according to claim 1, comprising at least one first energy storage unit which pretensions the multi-link hinge in a closed position.

6. A multi-link hinge according to claim 1, comprising at least one second energy storage unit which moves the linear damper back to its initial position.

7. A multi-link hinge according to claim 1, wherein the damping of the closing movement is effective at an opening angle of less than 50°

.

8. A multi-link hinge according to claim 1, wherein the damping of the opening movement is effective at an opening angle which is at most 35°

less than a maximum opening angle of the multi-link hinge.

9. A multi-link hinge according to claim 1, wherein the central portion of the pivoting range extends over an angular range of at least 30°

.

10. A multi-link hinge according to claim 1, comprising seven shafts, on which the plurality of link levers are connected to each other.

11. A multi-link hinge according to claim 1, wherein the central portion of the pivoting range extends over an angular range of at least 60°

.

12. A multi-link hinge according to claim 1, wherein the first driver is formed on a separate first actuating element which is fixed to the first one of the plurality of link levers.

13. A multi-link hinge according to claim 1, wherein the second driver is formed on a separate second actuating element which is fixed to the second one of the plurality of link levers.

14. A multi-link hinge according to claim 12, wherein the second driver is formed on a separate second actuating element which is fixed to the second one of the plurality of link levers.

15. A multi-link hinge according to claim 1, wherein the first driver is formed on a separate first actuating element which is releasably fixed to the first one of the plurality of link levers.

16. A multi-link hinge according to claim 1, wherein the second driver is formed on a separate second actuating element which is releasably fixed to the second one of the plurality of link levers.

17. A multi-link hinge according to claim 15, wherein the second driver is formed on a separate second actuating element which is releasably fixed to the second one of the plurality of link levers.
