MULTI-LINK HINGE Russian patent published in 2025 - IPC E05D3/16 E05F3/20 

FIELD: machine building.

SUBSTANCE: invention relates to multi-link joint. Multi-link hinge (1), in particular, for a refrigerator has mounting element (2), made with possibility of attachment to device housing, and hinge part (3) made with possibility of attachment to door and retained with possibility of rotation on mounting element (2) between closing position and a maximum opening position by means of a coupling mechanism having a plurality of coupling arms (4, 5, 6, 7), wherein hinge part (3) is loaded in closing direction in compression range by means of spring (10), wherein at least one linear damper (30) is provided with damper housing (31) and piston rod (32) movable relative to damper housing (31), which brakes the closing movement of hinge part (3) before reaching the closing position, wherein in the folded closing position the connecting mechanism levers (4, 5, 6 and 7) are nested one into another, multilink hinge (1) has a box shape, and opening angle can be determined by two parallel surfaces of mounting element (2) and hinge part (3), characterized in that damper housing (31) of at least one linear damper (30) is mounted inside lever (4) without possibility of rotation by means of retaining element (33), wherein retaining element (33) is attached to lever (4) of the coupling mechanism, and piston rod (32) can be retracted into damper housing (31) by means of actuator (14), wherein actuator (14) is installed on connecting mechanism additional lever (7), and also the technical result is achieved by a refrigerator containing such a multi-link hinge.

EFFECT: providing improved damping during the closing movement of the hinge part.
