Operate the tutor to move the double lock lever to the second position
To allow the rotation of the first locking lever.
The second operating means in the room and the locking member are linked in the state of being
An unlocked double lock state can be obtained. The second locking lever has a double lock lever.
Is formed so that it can engage with
The lock actuator has become inoperable due to a failure, etc.
Even if the 2nd locking lever, double lock lever
It can be rotated from the second position to the first position. This
As a result, double lock actuators
Even if the lock actuator is inoperable,
The bull lock state can be released. In addition, double row
There is little slip between the lever and the engaging part,
Locking in Engagement of Portion and Double Lock Lever
Low load transmission loss from lever to double lock lever
No operability deterioration due to heavy operation load etc.
The double lock state can be reliably released. Change
And the second locking lever engages with the double lock lever
The number of parts increases because only the engaging part
There can be no simple structure. In the double lock state, the first locking lever
-Double rotation is released because rotation is allowed.
Even if not Indoor Of the indoor and outdoor by the second operating means of
The link between the operating means and the pole can be disengaged.
This simplifies the operation of the door lock device,
The operability can be improved as compared with. Also,
Double lock when bull lock actuator is inoperable
By rotating the lever from the second position to the first position,
Since the bull lock state is released, the third place as before
No installation is required. This allows the operation of the door lock device
Has been simplified and its operability has been improved compared to the past.
Can be done. In addition, the double lock lever
Rotates integrally with the output member of the BullLock actuator
So double lock lever position and double lock activator
The position of the output member of the
Wear. This allows the output of the double lock actuator
When the positional relationship between the member and the double lock lever is matched
Work is not required, and double lock
When returning to an operable state due to repair of the tutor, etc.
Simplicity of the work and improve its workability
Can be.
