TAMPER-PROOF CYLINDER FOR LOCKS Russian patent published in 2019 - IPC E05B27/02 

FIELD: locks.

SUBSTANCE: lock-protected cylinder (1) for locks, comprising stator (2), in which there is a substantially cylindrical longitudinal cavity (3) for accommodating rotor (4) with longitudinal recess (5) for inserting key (6). Rotor (4) and stator (2) comprise multiple channels (7), which are substantially aligned with each other and face each other when cylinder (1) is in closed configuration. In channels 7 there are corresponding coding pins (8), driving pins (9) and, if necessary, resilient means (7a), tuned to prevent rotation of rotor (4) in stator (2) with no key (6) in longitudinal recess (5). At least one of driving pins (9) comprises rod (10) arranged with clearance with possibility of sliding in that part of channel (7), which is located in stator (2). Rod (10) has mushroom-shaped end (11) having a smaller diameter than rod (10). End (11) faces the corresponding coding pin (8) and is located next to it. At least one contour annular body (13) with diameter, which is substantially equal to diameter of channel (7), is put on mushroom-shaped end (11) with a gap.

EFFECT: disclosed is a lock cylinder for locks.
