ANTI-BREACH CYLINDER Russian patent published in 2021 - IPC E05B27/00 

FIELD: building.

SUBSTANCE: invention relates to an anti-breach cylinder, particularly, a cylinder comprising an actuating handle on one side and a hole for inserting an actuating key. The anti-breach cylinder (1) is comprised of a fixed stator (2) with a cavity (3) wherein no less than one rotor (4, 4a, 4b) can rotate, made uniform in the central section thereof, with an actuating cam (5) for no less than one sliding latch. The rotor (4, 4a, 4b) is connected with a movable handle (6) at one end and comprises the hole (7) for the code key (8) at the other end. The hole (7) is covered by multiple code pins (9). No less than one rotor (4, 4a, 4b) is formed by two coaxial half-rotors (4a, 4b), wherein a longitudinal plug (10) connectable to the cam (5) is located between said half-rotors. The end head (11) of the plug (10) forming the end wall of the hole (7) for accommodating the key (8) has a protruding structure, preferably selected from conical, hemispherical, pyramidal, semi-ellipsoidal and the like.

EFFECT: creation of an anti-breach cylinder with a simple design, protective against acts of breach performed using of a drill, wherein an attempt of a breach will be easily detectable.
