DRIVE MECHANISM OF RECESSED HANDLE Russian patent published in 2021 - IPC E05B85/10 

FIELD: door manufacturing.

SUBSTANCE: invention relates to a drive mechanism for a door handle made with the possibility of moving between the non-working position, in which the handle is located flush with the door, and the working position, in which the handle protrudes relatively to the door and is connected to a door lock. Handle (1) is connected to the door lock by means of a door lock control body. The drive mechanism contains case (3) equipped with means of mounting on door (4), while the handle is made with the possibility of sliding in door opening (5). First lever (6) is installed with the possibility of rotation around first axis (8) installed in the handle. Second lever (11) is installed with the possibility of rotation around second axis (14) installed in the handle parallel to first axis (8) at a distance from the first axis in the longitudinal direction of the handle. Thrust ends (10) are connected to first lever (6) and to second lever (11) by means of hinged joints, at least one of which has backlash (13) in the longitudinal direction of thrust. First lever (6), second lever (11), thrust (10) and handle (1) form a deformable quadrilateral, the deformation of which leads to the progressive movement of handle (1).

EFFECT: creation of a progressively moving drive mechanism with a small overall size is ensured.
