<p>PURPOSE: To perform the electric control, and to enable the use by a lock system and a bolt lock by unlocking the lock system from the center or operating it through a code circuit. CONSTITUTION: A lock 13c and a control pin 23 are provided on a control plate 13, and the pin 23 is engaged with a tumbler 14 and a moving piece lever 15. When a moving piece 15a is held by an energized magnet, the pin 23 presses the lever 15 downward, and a pivot 25 moves on a circular track around the moving piece 15a. As a result, the tumbler 14 is moved to the unlocking position. The control plate 13 is moved to the left, and halves 3, 4 are turned into a case 1 to release a bolt mechanism. When the bolt mechanism is again brought to the locking position, each half is returned into a notch, the control plate 13 is returned to a starting position, and the tumbler 14 is moved again to the locking position. In short, the bolt mechanism is unlocked only when the magnet 20 is energized.</p> |
