MULTI-LINK HINGE Russian patent published in 2021 - IPC E05D3/16 E05D11/00 E05F3/10 E05F3/20 

FIELD: mechanics.

SUBSTANCE: multi-link hinge (1) is proposed, containing the main part (2), on which the door support (3) is rotatably held with the help of a lever mechanism. The multi-link hinge (1) is made in the form of a seven-link hinge, and the lever mechanism contains four levers (4, 14, 16, 20) between the door support (3) and the main part (2), while inside the multi-link hinge (1) there is a damping element (30) for braking the closing movement and a spring element (40) for pulling the door support (3) in the closing direction in the closing area, wherein the damping element (30) and the spring element (40) are connected in parallel, while the spring element (40) has at least one spring (41) of linear action with a spring axis (43). At the same time the damping element (30) has at least one linear damper with the damper axis (33), and the damper axis (33) and the spring axis (43) are aligned to each other at an angle of less than 10° over the entire pivot area of the door support (3 ) and the damping element (30) and the spring element (40) are located adjacent to each other, while in the closed position the multi-link hinge has a substantially box-like shape formed by the main part (2), the door support (3) and levers (4, 14, 16, 20).

EFFECT: invention is aimed at improving the hinge performance and its manufacturability.
