Title:
PICKING PROTECTIVE LOCK, AND LOCKING SYSTEM USING THE SAME
Document Type and Number:
Japanese Patent JP3711047
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a means to make it very difficult to unlock a lock in spite of a relatively simple structure of the lock by disposing lock mechanisms and alarm mechanisms properly combined with each other inside the lock.
SOLUTION: This picking protective lock comprises a main rotor disposed inside a lock main body and comprising the first lock mechanism to be locked by a radial direction lock pin, and the second lock mechanism to be locked by an axial direction lock pin, and it is provided with the first alarm mechanism which is actuated by a side surface of a key, and the second alarm mechanism which is actuated by a tip of the key, when the lock is tried to be unlocked by the key of an irregular form. An auxiliary rotor is disposed on a front surface of the main rotor, so that the key hole shape of the main rotor becomes invisible from the outside in locking it. A double lock type locking system to further make it difficult to illegally unlock the lock by using above picking protective lock is also provided.
