Even when the sector 8 is forcibly rotated to the position E to rotate the sector 8 together with the door lock side swing arm 22 from the lock position B to the unlock position A, the output lever 1
Since 1 is not coupled to the free lever 10 together with the swing arm 20 on the lock knob side, the sector 8 cannot be rotated by an external force, and the door cannot be opened with the door lock unlocked.

The output lever 11 is elastically connected to the free lever 10 by a lever urging spring 12,
Even if the output lever 11 is rotated together with the lock knob side swing arm 20 by an external force, the lever biasing spring 12 does not have a biasing force for rotating the free lever 10, so that only the output lever 11 is swung.

Further, the door key inserted into the door outside key cylinder is moved in the reverse direction from the neutral position to the third position.
5 is turned to the key position, the power source in the reverse direction is connected from the door lock switch to the brush terminals 14b and 14c of the deadlock motor 14 in the deadlock operating state shown in FIG. Pin switching lever 1
5 returns from the engagement pin driving position H to the engagement pin non-driving position G and rotates, so that the engagement pin pressing portion 15c moves the engagement pin 1
The engaging pin 13 which is separated from the position 3 and is not pressed by the engaging pin switching lever 15 is brought into contact with the guide 11c of the output lever 11 by the elastic restoring force of the engaging pin return spring 18 and guided by the guide 11c. The engaging hole 1
The free lever 10 and the output lever 10 are integrally coupled by being engaged with 1e.

At the same time, since a reverse power source is connected to the brush terminals 3b and 3c of the door lock motor 3 from the door lock switch via the position switch 16, the door lock motor 3 has the armature shaft 3d reversed. The sector 8 rotates together with the swing arm 22 on the door lock side to rotate from the lock position B of the door lock to the unlock position A, and the free lever 10 returns to rotate from the second position D to the first position C, and rotates. The output lever 11 integrally connected to the free lever 10 is returned from the locked position F of the inside lock knob to the unlocked position E and rotated,
The state returns to the unlocked state shown in FIG.

At this time, even if the output lever 11 which is in the free state with respect to the free lever 10 is in any rotation position together with the swing arm 20 on the lock knob side, the output lever 11 is provided with the armature of the door lock motor 3. By the reverse rotation of the shaft 3d, the engagement pin 13 held by the free lever 10 is engaged while being guided by the guide 11c while the sector 8 rotates back from the lock position B of the door lock to the unlock position A. Since the engaging pin 13 is engaged with the hole 11e, the engaging pin 13 is promptly engaged with the engaging hole 11e by the elastic restoring force of the engaging pin return spring 18.
It will be synchronized in the same direction as the free lever 10.

Then, the engaging pin switching lever 15 engages the engaging pin 13 with the engaging hole 11e of the output lever 11 or moves the engaging pin 13 from the engaging hole 11e of the output lever 11. Switch to disengage and engage pin 1
Even when the lock knob side swing arm 20 is changed from the locked state to the unlocked state by an external force in a deadlock state in which 3 is disengaged from the engagement hole 11e of the output lever 11, the output lever 11 is separated from the free lever 10. As a result, the output lever 11 does not swing together with the lock knob side swing arm 20 to move the sector 8 and the door lock side swing arm 22, so that the door lock cannot be switched from the locked state to the unlocked state.

On the other hand, in the state shown in FIG. 6 in which the deadlock operation is performed, when an electrical failure such as battery exhaustion occurs, the door lock switch operates in the opposite direction to the brush terminals 14b and 14c of the deadlock motor 14. It becomes impossible to connect the power source, and the free lever 10 in the second position D and the sector 8 in the locked position A cannot be moved.

At this time, when the door key inserted into the door outside key cylinder is turned from the neutral position to the third key position in the opposite direction, the door lock side swing arm 22 at the lock position A is moved through the key rod. Since the door lock side swing arm 22 is rotated from the lock position A to the unlock position B by being manually rotated to the unlock position B, the free lever 10 and the output lever are connected via the power transmission rod 9. 11 is rotated from the second position D to the first position C.

The engaging pin switching lever 15 has a deadlock position H because the deadlock motor 15 does not move.
However, since the engagement pin 13 is disengaged from the engagement pin pressing portion 15d of the engagement pin switching lever 15 while the free lever 10 is being rotated from the second position D to the first position C, The engaging pin 13 is engaged with the engaging portion 11e by the guide 11c of the output lever 11, the output lever 11 is coupled to the free lever 10, and the door 8 is locked in response to rotation of the sector 8 to the unlock position B. Side swing arm 22
Rotates to the unlock position B of the door lock to unlock the door lock, and at the same time, the output lever 11
In response to this, the swing arm 20 on the lock knob side rotates to the unlock position E of the inside lock knob and returns the inside lock knob to the unlock position.

As described above, in the deadlock state, even if the actuator 1 becomes immobile due to an electrical failure, the door key inserted into the door outside key cylinder moves from the neutral position to the third position in the reverse direction. When the door lock is unlocked by being rotated to the key position of, the free lever 10 and the output lever 11 that were in the uncoupled state are coupled and the inside lock knob is returned to the unlocked position. The door lock shown in FIG. 3 returns to the unlocked state.

As shown in the second embodiment of the actuator according to the present invention shown in FIG. 7, the output lever 11 is substantially L-shaped and the guide 11c is formed only on one side of the engaging hole 11e. However, in this case as well, the same operation as in the above-described first embodiment is brought about.

[0065]

As described above, according to the actuator of the first aspect of the present invention, the third lever has the first lever at the second position and the second lever at the inside lock knob. When the deadlock motor is rotated to move to the deadlock position when the lock lever is in the lock position, the engagement pin is disengaged from the second lever. Even if the lever of 2 is moved, the sector cannot be moved and the locked state of the door lock is maintained,
With the third lever in the deadlock position, when the deadlock motor becomes immobile due to an electrical failure such as battery exhaustion, the door key cylinder is operated by the key to move the sector to the unlock position side. When the first lever is rotated to the first position, the first lever is rotated toward the first position, the engagement pin is engaged with the second lever, and the first lever is coupled to the second lever. The lever of No. 2 is rotated to the unlock side of the inside lock knob, and the sector is rotated to the unlock side of the door lock to unlock the door. Since there was an electrical failure, the door can be opened and the safety in an emergency can be improved.

According to the actuators according to claims 2 and 3 of the present invention, similarly to claim 1, the door is opened when there is an electrical failure such as battery exhaustion in the deadlock state. To be able to
It has an excellent effect that the safety in an emergency can be improved.
