As shown by the two-dot chain line, it moves to the locked position protruding from the front 61.

Above the dead hub 73, the unlocking actuating bar 45a is located. When the unlocking bar 45a is moved upward, the rear end portion of the substantially L-shaped joint 82 is pushed up. This causes the joint 82 to rotate about the pivot fulcrum 83, and the front end thereof is pushed downward. The lower part of the front end of the joint 82 is connected to the joint transmission gear 79, and the rotation of the joint 82 causes the joint transmission gear 79 to rotate clockwise around the shaft fulcrum 81 on the front end side. This rotation is transmitted to the dead hub 73 via the toothed portion 79a of the joint transmission gear 79 and the toothed portion 73d of the dead hub 73, and the dead hub 73 rotates counterclockwise. As a result, the dead bolt 3 moves backward from the locked position to the unlocked position.

Further, the locking operation bar 100b of the locking operation member 100 is located above the joint 82,
When the locking operation bar 100b is moved downward as shown by the chain double-dashed line by operating the locking operation part 100a, the rear end of the joint 82 is pushed down.
As a result, the front end of the joint 82 is pushed upward, the joint transmission gear 79 rotates counterclockwise, and the dead hub 73 rotates clockwise. As a result, the dead bolt 3 moves forward from the unlocked position to the locked position.

The advancing operation and the retreating operation of the dead bolt 3 are provided on the dead bolt 3 as ON / OFF detecting means and an ON / OFF detecting switch which are ON when the dead bolt 3 advances and OFF when the dead bolt 3 advances. It is detected by the dead switch 103.

When the operating lever 8 is operated downward while being driven by the rotating latch hub 65 pushed by 04 and being held in the advanced position, the latch drive portion 6 for the latch bolt 2 is driven.
The pushing operation of 5a is released, and the latch bolt 2 is pushed by the backward drive spring 106 to move to the backward position.

Therefore, as described above, in the locked state where the dead bolt 3 of the lock 4 has advanced, the keyless locking device 5
When the operation lever 8 is operated after the operation of the aligning push button in step 1, the unlocking operation bar 45a moves upward,
As a result, the dead bolt 3 is retracted, and the switching operation to the unlocked state occurs. At this time, at the same time, the latch bolt 2 is also retracted, and the door 1 can be opened.

Further, in the keyless locking device 5,
When the operating lever 8 is operated, each component is automatically returned to the initial position.
That is, as described above, when the retractor hub 41 is rotated and the retractor 42 is moved upward together with this, the reset operation body 26 is also moved up with a slight delay. That is, as shown in FIG.
2 The lower end surface 27d of the reset bar 27 is located slightly above the engaging surface portion 42a at the upper end, and the engaging surface portion 42a abuts against the lower end surface 27d from below and pushes it up. ing.

As the reset operation body 26 rises in this way, the locking projections 28a ... Of the reset bar spring 28 move above the sensor chips 31. As a result, the pushing operation of the push button 34 is performed in advance, and the sensor chip 31 held in the retracted position is released from the locked state by the locking projection 28a. Therefore, when the sensor plate 29 is in an immovable state, that is, when the alignment push button operation is not performed, the cutout recesses 29b ... Of the sensor plate 29 are located at the same height position as each sensor chip 31. At that time, the sensor chip 31 is returned to the initial position through the cutout recesses 29b ... By the spring force of the chip setting spring 35.

On the other hand, when the sensor plate 29 rises with the upward movement of the retractor 42, that is, when the aligning push button operation is performed in advance, the sensor chip 31 located in the retracted position first The rear edge portion of the opening 31h is the cutout recess 29 of the sensor plate 29.
While moving forward until it comes into contact with the wall surface between b and 29b, and then the hand is released from the operating lever 8 to return the operating lever 8 to the initial position, the retractor 4 and the retractor 4 are integrally formed with this.
2 and the sensor plate 29 are respectively lowered and when the height positions of the cutout recesses 29b are the same as those of the sensor chips 31, the cutout recesses 29b are returned to the initial positions through the cutout recesses 29b.

Further, in the keyless locking device 5,
With the number changing panel 93 pushed forward and locked by the panel locking spring 92, the sensor chip 31 is pulled out and rotated by 180 °, and then returned to its original position to change the unlocking combination number. It is possible.

Further, the lock operation detecting switch 102 shown in FIG. 1 and the dead switch 103 shown in FIG.
Are incorporated in the presence / absence detection circuit 108 shown in FIG. In this circuit 108, the lock operation detection switch 102, dead switch 103, and relay 109 described above are provided.
The electromagnetic coil 109a is connected in series, and the lock operation detection switch 102 is connected in parallel with the relay contact 109b. A power source (not shown) is further connected in series to the presence / absence detection circuit 108. Further, the relay 109 is provided at an appropriate position in the keyless locking device 5, or in a position near the keyless locking device 5, for example, in the door 1. Therefore, the presence / absence detection circuit 1
The output of 08 is drawn out by two power supply lines 110, 110, and is connected to a display unit such as a display lamp in a control room.

In the above structure, when the locking operation portion 100a of the locking operation member 100 is pushed down from the outside of the door 1 for locking, the locking operation detection switch 102 is turned on as described above. With dead bolt 3
Moves into the locked state and the dead switch 103 is turned off.
N, the presence / absence detection circuit 108 is closed. As a result, even when a current flows through the electromagnetic coil 109a and the relay contact 109b is turned on, and the operation of the locking operation section 100a is released and the locking operation detection switch 102 is turned off, the presence / absence detection circuit 108 operates. The closed state is maintained. Therefore, when the display unit, that is, for example, the display lamp is lit, the user goes out, that is, the absence state is displayed.

In the above state, when the aligning push button operation and the operation lever 8 for the keyless locking device 5 for unlocking are performed from the outside of the door 1, the dead bolt 3 retreats, Dead switch 1 in unlocked state
03 is turned off. Therefore, the presence / absence detection circuit 108 is opened, the current flowing through the electromagnetic coil 109a is cut off, and the relay contact 109b is turned off. The lock operation detection switch 102 remains OFF because the lock operation unit 100a is not operated. Therefore, the presence of the room is notified by the display unit, that is, by turning off the display lamp, for example.

On the other hand, when the thumb turn 12 is operated from the inside of the door 1 for locking or unlocking, the dead switch 103 is simply switched ON / OFF, and the locking operation detection switch 102 is always in the OFF state. Therefore, the presence / absence detection circuit 108 is always in the open state. Therefore, the state of presence in the room is notified by the display unit.

As described above, in the keyless locking device 5, the presence / absence detection circuit 108 has a simple structure, and the two power supply lines 110, 110 send signals indicating the going out and the presence in the room to the display section. Therefore, the construction is easy and the cost is low.

In place of the presence / absence detection circuit 108, as shown in FIG. 18, a trigger switch 112 for detecting the opening / closing of the door 1 is further provided with a going-out detection circuit 111 connected in series. Since the presence / absence detection circuit 111 is closed only when the operation for locking the door 1 from the outside is performed in the closed state of the door 1, it is possible to more accurately detect the going-out state.
