Abstract
A multi-joint hinge has a mounting element which can be fixed to an appliance body and a hinge part which can be fixed to a door and which is held pivotably on the mounting element via a joint mechanism with a plurality of joint levers. The hinge part is biased in the closing direction via a spring and at least one linear damper with a damper housing and a piston rod displaceable relative to the damper housing is provided which brakes a closing movement of the hinge part. The linear damper is arranged with the damper housing in a rotationally fixed manner via a holding element within a lever and the holding element is fixed to a lever of the joint mechanism. The piston rod can be pushed into the damper housing via an actuating element which is arranged on a further lever of the joint mechanism.

A multi-joint hinge (1) for a refrigerator, comprising a mounting element (2) configured to be fixed to an appliance body and a hinge part (3) which is configured to be fixed to a door and is held pivotably on the mounting element (2) between a closed position and a maximum open position via a joint mechanism having a plurality of joint levers (4, 5, 6, 7), wherein the hinge part (3) is biased in a closing direction in a contraction range via a spring (10) and at least one linear damper (30) with a damper housing (31) and a piston rod (32) displaceable relative to the damper housing (31) is provided, which brake a closing movement of the hinge part (3) before the closing position is reached, wherein the at least one linear damper (30) is arranged with the damper housing (31) in a rotationally fixed manner via a holding element (33) within a first one of the levers of the joint mechanism, wherein the holding element (33) is fixed to the first lever (4) of the joint mechanism, wherein and the piston rod (32) is configured to be pushed into the damper housing (31) via an actuating element (14) that pushes the piston rod (32), the actuating element (14) being arranged on a further lever (7) of the joint mechanism,
- wherein in the closed position, the levers (4, 5, 6, 7) of the joint mechanism are nested inside each other and the multi-joint hinge (1) is box-shaped.
