Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a door lock device such as a locker, and an electric lock, a lock dedicated to a lock used when the electric lock fails, and an operation lever for opening and closing the door are unitized together with a puller. It is an improvement so that the door lock can be configured at the same time.

[Prior art]

When using an electric lock for a door lock device such as a locker, as a countermeasure when the lock cannot be unlocked due to a failure of the electric lock, a normal lock used only for unlocking operation is installed side by side, and a lock provided by a separate key is used. To release the operating lever that is locked. The electric lock is provided with a pair of solenoids used for locking and unlocking, and the opening / closing mechanism operated by the solenoids controls the operation lever for opening and closing the door.

[Problems to be solved by the device]

The work of attaching the electric lock that is associated with the operation lever to the door and the lock for unlocking the door is performed individually, so workability is extremely poor in terms of positioning, etc.
Since the lock and the operating lever provided on the pulling part of the door are relatively distant from each other, a relatively wide space is required for the mounting, and there is a problem that the number of parts for assembly and the like also increase. . Therefore, an object of the present invention is to unitize an opening / closing mechanism of an electric lock associated with an operation lever for opening and closing a door and a lock exclusively for unlocking associated with the opening / closing mechanism together with a door puller. It is an object of the present invention to provide a door lock device such as a locker which can be assembled to a door and has a puller and a door lock at the same time, and which is improved so that the assembling work can be rationalized.

[Means for Solving the Problems]

In order to achieve the above object, a door lock device such as a locker, which is a feature of the present invention, forms a frame for a puller that is fitted and fixed in a mounting hole provided in a door, and the frame of the frame is A supporting frame is connected to the open surface side, and an operating lever is provided on one side portion of the supporting frame, and the operating lever is mounted on a support shaft rotatably supported on the one side part. A locking piece extending in the direction opposite to the operation lever is provided in a protruding manner, and the other side portion of the support frame, which is the protruding side of the locking piece, is positioned on both sides of the locking piece for unlocking. A solenoid and a locking solenoid are attached, a lock is attached to the frame side, and the tip of the opening piece installed on the support frame side so as to be pushed and slid by the operating piece of the lock has the above A locking element protruding and retractable is projected on the locking piece and the opening piece While connecting to the actuation rod of the unlocking solenoid, the actuating rod of the locking solenoid is rotatably coupled to a stopper whose tip is abuttable against the side surface of the unlocking piece of the opening piece. In addition, the support shaft and the two operating rods are placed under the action of return springs.

[Action]

At the time of locking, the locking element abuts on the locking piece, and the operation lever connected to the locking piece via the support shaft cannot rotate. In order to unlock, the unlocking solenoid should be turned on and the locking element should be retracted together with the release piece so that the locking piece can be rotated. Since it is in contact with the side surface, the lock cannot be returned onto the locking piece even if the unlocking solenoid is turned off, so the door can be opened and closed by operating the operating lever. To lock, turn on the locking solenoid, turn the stopper by the backward movement of the operating rod, and unlock the open piece by this stopper. As a result, the original non-operating position is restored, and the locking piece comes into contact with the locking piece to complete the locking. At the time of locking, since the tip end side of the rotated stopper is located on the upper edge of the opening piece on the tip end side, the stopper is held at the turning position even when the locking solenoid is turned off. On the other hand, when the lock cannot be unlocked due to a failure of the electric system or the like, the lock can be operated by pressing the unlocking piece with the actuating piece by operating the lock with a duplicating key so that the lock can be released from the locking piece and unlocked.
