<p><P>PROBLEM TO BE SOLVED: To provide a lock mechanism enabling a key and equipment to be smoothly taken out in an event of a disaster. <P>SOLUTION: A lock mechanism comprises: a lock body 41 which operates between a lockable position and an unlocking position in a closed state; energizing means 42 to energize the lock body 41 in a direction toward the unlocking position by a repulsive force, which is accumulated when a control force is applied from an outside, in a state that the control force is released; restriction means 43 to restrict the energizing means in a state that the repulsive force is accumulated therein; and an actuator 44 to release the restriction of the restriction means when receiving a disaster striking signal to be sent out by a predetermined device. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
