ELECTROMECHANICAL LOCK Russian patent published in 2018 - IPC E05B47/02 

FIELD: construction.

SUBSTANCE: electromechanical lock contains base 4, closed with a lid. On the lid and base, there are grooves for the bolt bush fixed to the plate installed on the door. In the closed state of the lock, the bolt bush is fixed by clamp 10, which is locked from rotation by clamp poplock 32. At the mounting location of axis 29 of clamp poplock 32, permanent magnets 35, 36 are arranged on the side surface. The interaction of the permanent magnets with the magnetic conductor 39 offset from axis 29 of poplock 32 provides the initial state of poplock 32. For a normally closed lock, the magnetic conductor is shifted to the left, for normally open-to the right. When electromagnet coil 41 is energized, its field, interacting with the fields of permanent magnets 35, 36, creates a force that rotates clamp poplock 32 and permits the rotation of clamp 10. The lock is ready for opening. When opening the door, under the influence of bolt bush, clamp 10 rotates, torsion spring 15 is first compressed, and eventually released, fixing clamp 10 in the open position of the lock. When closing the door, under the influence of bolt bush, clamp 10 rotates, at the outset of the movement squeezing spring torsion 15, and at the end of the movement, clamp 10 turns under the influence of releasing spring 15, pressing clamp 10 to bolt bush 20. When moving, clamp 10 with the lower end surface urges clamp poplock 32, which occupies the position that blocks the possibility of turning clamp 10 in the closed state of the lock. The lock is closed.

EFFECT: excludes the possibility of unauthorized access and the ability to access when power is lost.
