SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an application in which opening / closing management of a plurality of doors is performed with a single key while another door is open. It is providing the door lock handle apparatus which can ensure all the doors of a closed state. Means for Solving the Problems The lock hand of the present invention
One device is installed in each of the doors 1 to be managed for opening and closing.
The door lock handle device is fixed to the door 1
A handle storage portion 2 and a lock storage portion 3 are formed in the housing 4 adjacent to the front side, and are raised around a pivot 5 at the base end.
A locking plate 8 interlocks with the rotating handle 6 and locks the door 1 against the fixed frame 7 so that it cannot be opened.
The dead bolt 10 interlocked with the rotor 9 enters the recess 11 at the tip of the handle 6, restrains the handle 6 in the fall position, and inserts the stopper into the through hole 12 of the back wall 4a of the housing 4. Pin 13 is pushed forward by spring member 14 and inserted
Then, the stopper pin 13 protruding into the handle housing portion 2 is pushed back by the handle 6 so that the dead bolt 10
The lock unit 12 is configured so that the key 15 can be removed when the distal end portion 10a enters the recess 11 of the handle 6.
In the door open state in which the handle 6 protrudes from the housing 4, the tip 10 a of the dead bolt 10 is disposed so as to abut against the side surface of the stopper pin 13, and a plurality of doors are arranged.
One key 15 is used for the lock handle device
It is what I did. A plurality of cabinets for storing devices are installed in parallel, and the door lock handle device of the present invention is attached to each cabinet, and a single key is provided for the plurality of door lock handle devices. In the application form in which 15 is assigned for management, after the inspection and repair of the equipment stored in a certain cabinet and the required operation are completed, the door 1 is closed and the handle 6 is rotated. As a result, the stopper plate 8 is engaged with the receiving portion 16 of the fixed frame 7 which is a part of the cabinet. After the door 1 is locked to the fixed frame 7 in this way, the handle 6 is housed in the handle housing portion 2 of the housing 4 and the key 9 rotates the rotor 9 of the lock unit 12 in the locking direction. Then, the dead bolt 10 of the lock unit 12 engages with the recess 11 at the tip of the handle 6, and the handle 6 is locked to the housing 4 in this lying down position. In this locking position, the key 15 is removed from the lock unit 12 in order to unlock and open the door of the cabinet in which the next device to be operated is stored. When an operator who goes to the next cabinet inserts the key 15 into the lock unit 12 of the door lock handle device mounted on the door 1 and rotates the rotor 9 of the lock unit 12 in the unlocking direction. The dead bolt 10 escapes from the recess 11 at the tip of the handle 6, so that the housing 4
The handle 6 is unlocked. When the handle 6 protrudes from the handle storage portion 2 of the housing 4, the stopper pin 13 that has been pushed by the back wall portion 11 a of the recess 11 moves forward by the bias of the spring member 14, and the handle storage portion 2 of the housing 4. The front end of the stopper pin 13 is inserted into the front end 10 of the dead bolt 10.
It will be located at the tip of the nose of a. The door 1 is opened by pulling the handle 6 toward the front, and inspection and repair of the equipment and operation are started by the worker. As described above, in the door open state in which the handle 6 protrudes from the housing 4, although the inspection and repair of the target device and the operation operation are not completed, the operator or other person makes a judgment error. This is not possible if the door 1 is closed and the key 15 is withdrawn from the lock unit 12 to open another cabinet. That is, when trying to rotate the rotor 9 of the lock unit 12 with the key 15, the dead bolt 10 linked to the rotor 9 tries to enter deeply into the handle housing part 2, but such movement is in a protruding state. When the tip 10a of the dead bolt 10 abuts against the side surface of the stopper pin 13 located immediately there, it is immediately blocked. Thus, the key 15
Therefore, there is no risk that the door 1 is left open, and two or more doors cannot be opened at the same time. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, a housing cylinder 4 is formed with a bearing cylinder portion 17 projecting in the front-rear direction on the opposite side of the lock storage portion 3 in the housing 4.
