ELECTROMECHANICAL LOCK Russian patent published in 2021 - IPC E05B51/02 

FIELD: locks.

SUBSTANCE: electromagnetic lock relates to the field of security equipment, particularly, to locking apparatuses controlled by means of electronic technology. The lock can be used to lock sliding doors in order to exclude the possibility of unsanctioned access, and to open doors while unlocking the lock. The electromechanical lock is comprised of a base (1) installed whereon are: a fastener (5), a blocker (13) with a blocker lever (21) on axial sleeves (4), (20), spring-loaded by torsion springs (26), (27). In the closed state of the lock, the fastener (5) is restrained by the blocker (13) due to the interaction of the bevel surfaces (11) and the protrusion (23), and the blocker (13) is restrained by a flag (33) due to the interaction of the end surfaces of the protrusion of the blocker lever (23) and the cutting of the flag (33) located rotatably on the axis (40), holding the end surfaces in the closed state of the lock with a torsion spring (42). The bridge of the bolt therein is located in the area of the base (1) formed by the base groove (2) and the fastener groove (7). To open the lock, a voltage is applied to the outputs of the electromagnets (41), (42) the field of the electromagnets (29), (30) draws the flag (33) to the anchors (31), (32). The flag (33) rotates as a result, overcoming the impact of the flag torsion spring (42), and the protrusion of the blocker lever (23) exits the cutting of the flag (34), releasing the blocker lever (21) and the blocker (13). Under the impact of the blocker torsion spring (26) and the torsion spring (27), the blocker lever (21) rotates with the blocker (13) and the fastener (5), wherein the end bevel surface of the fastener (11) and the end surface of the second side (17) of the protrusion (16) are disengaged, releasing the fastener (5) for further rotation. When the lock (5) is rotated under the impact of the torsion spring (27), the bridge (50), abutting the lower end surface of the fastener groove (7), pushes the bolt (47) from the base groove (2) together with the door. Upon the end of the movement, the fastener (5) and the blocker (13) with the blocker lever (21) take a position corresponding with the open state of the lock. The lock is opened, the bolt (47) with the door is removed from the base groove (2). When the voltage is removed from the outputs of the electromagnets (44), (45), the flag (33) under the impact of the flag torsion spring (42) rotates, abutting the end surface of the protrusion of the blocker lever (23). The lock returns to the original open state. The open and closed states of the lock are determined by the end switch (46) interacting with the end surface of the blocker lever (21).

EFFECT: expanded operational capabilities of the lock and eliminated external forces in opening the door required to overcome the friction forces and the forces of the torsion spring of the bolt are ensured.
