DOOR LOCK Russian patent published in 2022 - IPC E05B17/20 

FIELD: locking systems.

SUBSTANCE: invention relates to door lock, in which a split spindle is used. Door lock (1) contains lock case (2), crossbar (3), replica (4), leash (5A, 5B) installed on both sides of the replica, and latch assembly (6) for transfer of at least one of leashes (5A, 5B) to a force-transmitting connection to replica (4) and output of it from such a connection. Door lock (1) contains protective plate (7, 7A) installed between replica (4) and leash (5A, 5B) from at least one side of replica (4). Protective plate (7, 7A) contains at least one support surface (8A, 8B, 8C) pressed to the lock case or to a part, fixedly connected to the lock case.

EFFECT: protective plate does not have the possibility of rotation relatively to lock case (2), which prevents the transfer of rotating force from the leash to the replica.
