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 which can 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-like manner, wherein a linear damper is provided which dampens both a closing movement and an opening movement of the door bearing, 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 linear damper is actuated directly or indirectly by at least one of the link levers, wherein the at least one link lever is in engagement with the linear damper only outside of the central non-dampened portion of the pivoting range.

3. A multi-link hinge according to claim 2, wherein an actuation of the linear damper occurs indirectly via a lever kinematic system.

4. A multi-link hinge according to claim 2, wherein the at least one link lever actuating the linear damper directly or indirectly comprises at least one driver for the actuation of the linear damper.

5. A multi-link hinge according to claim 4, wherein at least one of the drivers is formed integrally on the link lever.

6. A multi-link hinge according to claim 4, wherein at least one of the drivers is formed on an actuating element, wherein the actuating element is fixed to the link lever.

7. A multi-link hinge according to claim 6, wherein the actuating element is releasably fixed to one of the link levers.

8. A multi-link hinge according to claim 6, wherein two actuating elements are provided which are fixed to two different link levers), wherein a first one of the actuating elements actuates the linear damper directly or indirectly during the closing movement and the second one of the actuating elements actuates the linear damper directly or indirectly during the opening movement.

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

10. A multi-link hinge according to claim 3, wherein the lever kinematic system comprises a separate shaft which is fixed to the fastening element.

11. 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.

12. 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.

13. 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°

.

14. 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°

lower than the maximum opening angle of the multi-link hinge.

15. 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°

.

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

17. 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°

.
