Since the lock is installed in the narrow space at the end of the door, there is a problem in that the work is impaired because the connection work is forced within the narrow work space.

It is also possible to connect the connecting member to the door lock in advance before mounting the door lock on the door and mount the door lock on the door in this state. To connect the connecting member to the door lock, the operating force from the actuator can be transmitted to the release lever of the door lock, but conversely, the movement of the release lever of the door lock cannot be transmitted to the actuator. Not good.

In the connection structure as described above, generally, the release lever is provided with a long hole corresponding to the operation amount of the connection portion with the connection member, and the connection member is movably engaged with the long hole. It's designed to work. However, due to the operating force of the actuator, the connecting member is formed at the end that is as far as possible from the rotation axis of the release lever, so the elongated hole becomes longer and the release lever becomes larger accordingly. There is a risk that the end of the release lever will interfere with other parts, and there is a problem that the size of the door lock will be increased.

In view of the above problems of the prior art, the present invention can simplify the connecting work, and can achieve the degree of freedom of layout and the miniaturization of the door lock. An object is to provide a door lock device for an automatic door.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the device of the present invention is configured such that an actuator is connected to a release lever of a door lock mounted on a door through a connecting member, and the door lock is unlocked by the operation of the actuator. In a door lock device for an automatic door, a standing piece facing the actuator is formed on a release lever of a door lock, and the standing piece is provided with a terminal portion at one end and the other end is connected to the actuator. It is characterized in that the collar is inserted and guided at one end, and the coupling member is coupled to the release lever so that the end portion of the coupling member comes into contact with the collar by the operation of the actuator and the release lever operates.

[0009]

[Action]

 By fixing the collar through which the connecting member is inserted to the upright piece of the release lever of the door lock, the connecting member can be easily connected to the door lock. After that, the actuator and the door lock are respectively arranged at predetermined positions of the door, and the other end of the connecting member is connected to the actuator, so that the actuator and the door lock are connected. When the actuator operates and the connecting member moves, the end portion of the connecting member comes into contact with the collar and the release lever moves in the releasing direction.
