Description

[Detailed description of the invention] (Field of industrial application) In this invention, both keys A and B cannot be removed unless the solenoid is energized. By removing the key, key A can be removed by rotating it in the same way, and when storing the key, insert key A and rotate it in a predetermined direction to fix it, and then remove key B in the same way. The present invention relates to a solenoid type key box device that can be rotated and fixed so that it cannot be removed.

(Prior art) In a conventional key box, multiple keys are stored independently of each other, and there is no restriction on taking out or storing them, and each key cannot be taken out by each other. I was free to

(Problem that the invention aims to solve) By the way, in multiple work processes placed in a certain series, the opening and closing order of the doors equipped inside with equipment related to each work becomes an important problem. However, if each worker is left with the freedom to use the keys for multiple doors as described above, if the order of opening and closing of each door, or the order of operation of each device, is incorrect, it will only delay the progress of the work. Otherwise, there is a risk of personal injury.

Therefore, in order to manage the safety of work processes, the present invention allows multiple groups of doors in rooms where equipment is installed, storage cases, etc., to be opened and closed only in a predetermined order, and restricts opening and closing operations in any other order than the predetermined order. An object of the present invention is to provide a solenoid type key box device.

(Means for Solving the Problems) The solenoid type keybox device of the present invention will be explained below using reference numerals in the attached drawings.
The insertion/extraction position is 1, which is fixed to the mounting board 3 side by side.
A solenoid 1 is fixed to the mounting board 3 and has a plunger 6 moving in and out between the locks 7A and 7B, and a solenoid 1 is installed in conjunction with the rotor 12 of the lock 7B to move the key 2B inserted into the lock 7B in a predetermined direction. a slide plate 4 that moves toward the lock 7B when the lock 7A is rotated; a dead bolt 5 that is fixed to the back surface of the slide plate 4 and has a shoulder portion 5a on which the tip of the plunger 6 of the solenoid 1 engages and disengages; It consists of a rotating strike 15 connected to a rotor 8 and having a recess 15a in a part of its circumferential surface into which the tip 5b of the dead bolt 5 engages and disengages, and the keys 2A and 2B inserted into the locks 7A and 7B cannot be removed. When the dead bolt 5 is turned to the position, the dead bolt 5 is in the circumferential recess 15a.
The plunger 6 engages with the shoulder portion 5a of the dead bolt 5.

(Function) In the state shown in FIG. 3, the key 2A of the lock part 7A and the key 2B of the lock part 7B are both fixed and cannot be removed and used to operate the corresponding equipment.

Here, when the solenoid 1 is energized, the tip 6a of the plunger 6 comes off the shoulder 5a of the dead bolt 5, so that the dead bolt 5 fixed to the front of the slide plate 4 can hold the key 2B of the lock part 7B in the first position. By rotating it 45 degrees counterclockwise in the figure, it can be moved to the right in FIG. 3, that is, in the direction of the lock part 7B. Key 2B can be removed when it has rotated to that point.

Due to the movement of the slide plate 4, the tip 5b of the dead bolt 5 escapes from the circumferential recess 15a of the cylindrical rotating strike 15 fixed to the rotor 8 of the lock portion 7A.
and the rotating strike 15 becomes rotatable (sixth
condition). Therefore, if the key 2A is rotated 45 degrees counterclockwise in FIG. 1, the key 2A can be removed.

When the key 2A is rotated to the extraction position,
The tip 5b of the dead bolt 5 rotates as the strike 1
5 (state shown in Figure 7).
Therefore, the key 2B is inserted into the lock part 7B before the key 2A.
Even if the dead bolt 5 is inserted into the rotor 12 of the lock portion 7B and an attempt is made to rotate the rotor 12, the movement of the dead bolt 5 is restrained by the circumferential surface of the rotating strike 15, so the rotor 12 of the lock portion 7B cannot be rotated.

Insert key 2A first and turn clockwise in Figure 1.
When rotated by 45 degrees, the circumferential recess 15a of the rotary strike 15 returns to the position facing the tip 5a of the dead bolt 5 (the state shown in FIG. 6), making it possible to insert and rotate the key 2B.

When the key 2B is rotated 45 degrees clockwise in FIG. 1, the tip 5b of the dead bolt 5 enters the circumferential recess 15a of the rotary strike 15, making it impossible to rotate and remove the key 2A. Further, since the plunger 6 of the solenoid 1 is lowered by the action of the return spring 17 and engages with the shoulder portion 5a of the dead bolt 5 (the state shown in FIG. 5), the key 2B also becomes unable to rotate or be removed. In order to release the locks on both keys 2A and 2B, the solenoid 1 must be energized again as described above.

(Implementation) In the embodiment shown in FIG. 3, the drive pin 10 of the cam plate 9 fixed to the rotor 12 of the lock part 7B is engaged with the receiving groove 18 of the slide plate 4, and the left and right sides of the slide plate 4 are In the guide slots 13 and 14,
The end of the rotor 8 of the lock part 7A and the end of the rotor 12 of the lock part 7B are fitted.

In the embodiment shown in FIG. 6, the return spring 17 of the solenoid 1 acts in a direction to cause the plunger 6 to protrude from the solenoid main body, and causes the tip 6a of the plunger 6 to come into contact with the deadbolt abdomen 5c, and the shoulder 5a of the deadbolt 5. automatically engage.

(Effect of the invention) As described above, in this invention, two keys A and B are restrained by one solenoid, and two keys A and B must be inserted and rotated in a predetermined order. No. That is, since the two devices for which the two keys A and B are used must be started and stopped in a predetermined order, multiple work processes can be accurately managed on the safe side.
