ELECTROMECHANICAL LOCK Russian patent published in 2023 - IPC E05B47/00 

FIELD: locking devices.

SUBSTANCE: invention relates to electromechanical locks with a bevelled bolt, in particular to locking devices controlled by electronic equipment. The electromechanical lock comprises a body (1) with a bracket (10) installed on the bottom (6). A guide bar (15) is installed in the notch of the bracket (14) with the possibility of movement. Permanent magnets (24) and (25) are installed on the mounting plate (20) of the guide bar (15). A locking bar (26) with a bend (27) is formed on the base. The limb (27), interacting with the notch of the locking (50) of the lever (19), ensures the open or closed state of the lock by fixing or releasing the rotation of the lever (19) by the armature (42) of the electromagnet (39). The movement of the crossbar (29) when opening the lock is carried out due to the force generated by the fields of magnets (21), (22) and (58), (59) located on the lining (54) installed on the door jamb. In the initial state of the lock, with the door open, the first (22) and second (23) magnetic cores, under the action of the compression spring (35), are adjacent to the front wall (2) of the housing (1). The beveled part of the crossbar (28) protrudes above the outer surface of the front wall (2) of the body (1). The bend (27) of the lock bar (26) is located in the notch of the lock (50) lever (19). The notch of the lever (52) is located opposite the end surface of the first part of the armature (44), blocking the possibility of turning the lever (19) and moving the guide bar (15). When the door is closed, the magnets (24) and (25) are located opposite the magnets (58) and (59), creating a force acting on the fixing plate (17). The lock is opened by the anchor (42) of the electromagnet (39), which releases the lever (52), allowing, under the action of the forces of the magnetic field, its rotation and the movement of the guide bar (15) with the bolt (28) inside the body (1). The lock opens. With the door open and the electromagnet (39) de-energized, the interaction forces of the magnets (24), (25), (58), (59) are absent due to their remote location. Under the action of the force of the compressed spring (35) on the fastening plate (17), the bolt (28) protrudes from the body (1) and the lever (19) turns and takes the position corresponding to the initial position of the lock.

EFFECT: simplified technical implementation and increased reliability of the electromechanical lock due to the exclusion of mechanical interaction of the lock elements located on the door and the door frame.
