Abstract

A hinge for a movable furniture part which is accommodatable on a furniture body of an item of furniture, wherein the hinge displays a first attachment part which, via an articulation mechanism, is pivotably connected to a second attachment part, wherein the articulation mechanism comprises articulation levers, and wherein a further lever which acts on a damper assembly of the hinge and which is pivotably accommodated by way of a separate axle, and, in the case of a pivoting movement according to the intended use of the hinge, is temporarily engaged on a guide portion on the hinge, wherein the further lever, prior to an engaging operation, assumes a predetermined ready position from which the further lever engages on the guide portion.

Claims

1. A hinge for a movable furniture part configured to be attached to a furniture body of a furniture item, wherein the hinge comprises:

a first attachment part configured to be attached on the furniture body; and

a second attachment part configured to be attached on the movable furniture part of the furniture item,

wherein the first attachment part is pivotably connected to the second attachment part via an articulation mechanism, and

wherein the articulation mechanism comprises articulation levers that are mounted via articulation axles;

a guide lever extending in a longitudinal direction and having a front face, a rear face, a first leg, a guide face having a guide edge inclined from the rear face towards the front face, and a groove extending in the longitudinal direction between the first leg and the guide face; and

a further lever which acts on a hinge damper assembly, the further lever is pivotally accommodated via an axle separate from the articulation axles and further comprises a bearing portion on an end opposite the axle;

wherein during a normal operation of the hinge, the further lever assumes a predetermined ready position in which the bearing portion of the further lever is aligned to engage the groove along the longitudinal direction via an opening;

wherein during an abnormal operation of the hinge in which the further lever has become misaligned with the groove and is in a position different from the predetermined ready position, the bearing portion of the further lever engages the inclined guide edge of the guide lever in a direction substantially orthogonal to the longitudinal direction such that the bearing portion slides over the inclined guide edge and engages with the groove to resume normal operation of the hinge.

2. The hinge according to claim 1, wherein the guide edge is formed with an engaging portion on a side facing the groove to prevent the bearing portion from sliding out over the guide edge during normal operation of the hinge.

3. The hinge according to claim 1, wherein the further lever is configured to act on a portion of a component of the first attachment part.

4. The hinge according to claim 1, wherein the guide lever is accommodated between two articulation axles of the hinge.

5. The hinge according to claim 1, wherein the groove of the guide lever is raised or sunken in relation to adjacent regions.

6. The hinge according to claim 1, wherein the further lever is pivotably mounted on one of the attachment parts.

7. The hinge according to claim 1, wherein the hinge is configured as a knuckle-joint hinge.

8. The hinge according to claim 1, wherein the hinge is configured as a wide-angle hinge.

9. A furniture item having a movable furniture part attached on a furniture body of the furniture item, wherein the furniture item comprises a hinge according to claim 1.

10. The furniture item according to claim 9, wherein the movable furniture part is a door.

11. The furniture item according to claim 9, wherein the movable furniture part is a flap.
