For a lock of the closure system comprising a cylinder and an outer gasket safety with control knob, a cylinder of the corresponding safety and lock comprising the said system

摘要

The lock system comprises a cover (G) with a button having an activating part (57) activating the locking means and a safety cylinder (C) comprising a double stator unit (1) defining first and second stators (3a,3b). A bit (6) engages the locking means. A barrel rotor (10) in the first stator, with a key housing (11), operates the stator. A first de-clutchable transmission (31) can rotationally connect the rotor with the bit, and a second transmission (20) in the second stator can engage the button activating part in order to rotationally connect the button with the bit. Independent claims are included for a safety cylinder and a door lock comprising the system.
