<p>PURPOSE: To unlock a door kept at the dead lock state regardless of battery exhaustion by arranging a rotation blocking mechanism between a lock knob and the latch plate of a lock device main body. CONSTITUTION: A control device 24 outputs the dead lock signal when a dead lock is operated. A lock device main body 2 locks and unlocks a door, and it has a latch plate 6. A lock knob 11 is installed on the car room inside of a door, and it is connected to the latch plate 6 via a rod 14. A rotation blocking mechanism 10 blocks the rotation of the latch plate 6 in conjunction with the lock knob 11 when it receives the dead lock signal from the control device 24. The rotation blocking mechanism 10 is provided with a rod 14 connected to the latch plate 6 at one end, knob rods 12, 13 connected to the lock knob 11 at one end, and a solenoid allowing the rod 14 to be interlocked with the knob rods 12, 13 at the time of unlocking and locking and blocking the rod 14 from being interlocked with the knob rods 12, 13 at the time of dead lock.</p> |
