METHOD OF USE OF MECHANICAL LOCK Russian patent published in 2003 - IPC

FIELD: manufacture of locks. SUBSTANCE: according to the claimed method, lock is opened and closed by acting of control members through devices of code reception, sensing and fixing by actuator. In course of closing, lock combination degree is set up, and in lock opening with lock low combination, lock is acted upon by one control member. With combination degree set up by one control member, devices of code sensing and fixation engageable with other control member are interlocked, and with higher combination degree, devices of fixation engageable with both control members are mutually interlocked. During lock opening, with lock of higher combination degree, lock is acted upon by both control members by their location in two recesses. The first and second control members are used in form of keys, or the first control members are used in form of keys, or the first control member is used in form of key and releasing device operating during closing, and the second control member is used in form of key. Setting up of degree of lock combination and interlocking of devices of code sensing and fixation are effected from lock both sides. In setting of lock low degree of combination, device of code reception engageable with other control member is interlocked. In lock closing, high degree of its combination is set up by the first control member. EFFECT: improved conditions of lock use and higher degree of its combination with its negligible lowering in course of lock use. 3 dwg
