Description

[Detailed explanation of the invention] A. Industrial application field This invention is based on the invention: when the emergency door of a coin locker is opened, the master key is inserted from the front, the master key is used to operate the master lock, and the customer lock pops out in the first step. This invention relates to a newly devised emergency unlocking device for a coin locker, which allows the customer lock to be easily replaced using a second-stage operation, and allows emergency unlocking and relocking without a coin.

B. Conventional technology When a user locks a coin locker, the user loses the customer key, or after opening the door to check the contents for security reasons, the user loses the customer key. If you realize that you entered the wrong number or the security check has been completed, you will need to close the door again with the coin locker still in use, but with normal locking devices, once the coin is locked, the coins will not fall out. Once the door has been opened, the system will not allow you to lock it again unless you insert a coin again.

In the case of such an emergency opening door, it is desirable to be able to relock the door without using a coin.

Therefore, in order to solve this problem,
No. 15186 has already been proposed.

This invention comprises a master lock from the top to the bottom, a connecting plate (rotation prevention plate) that moves up and down when the master lock is driven, and a customer lock that connects and detaches the connecting plate by moving the connecting plate up and down. By driving the master lock, pulling down the connecting plate, separating the connecting plate from the customer lock, and then operating the customer lock, it is possible to emergency unlock a locked lock and relock it without a coin. It's summery.

C. Problems that the invention aims to solve As mentioned above, in the conventional invention, the customer lock had to be additionally operated after the master lock had been operated, which required double effort.

In particular, in the case of relocking without a coin, only the outer barrel of the customer lock, which slightly protrudes from the front plate, must be rotated, which is extremely inconvenient in handling.

Further, it is almost impossible to provide a taper on the outer edge of the outer cylinder of the customer lock, which is disadvantageous in that the shape and design of the customer lock is restricted.

D. Means for solving the problems The present invention was made to solve the above-mentioned drawbacks. By simply operating the master lock, you can attach and detach the customer lock, and unlock the locked lock in an emergency manner without using coins. To provide an emergency unlocking device for a coin locker that can be relocked.

The means for achieving the above object is provided in a coin locker in which a coin slot 4 and a coin return slot 5 each having a master lock 2 and a customer lock 3 attached to the front plate 1 are installed integrally with the master lock 2. A rotating actuation plate 9 is attached to the back side of the front plate 1, and the actuation plate 9
A pin 16 is installed to raise and lower the rotation prevention plate 12 to which the customer lock 3 is fixed, and by lowering the rotation prevention plate 12 with the rotation of the master lock 2, the customer lock 3 can be taken out and replaced. The coin checker 34 is pushed by the rising claw piece 44 of the rotation prevention plate 12.
is removed from the coin passage 47, and by further rotating the master lock 2, the pin 15 of the actuating plate 9 is removed from the notch 13 of the rotation prevention plate 12, and the recess of the swing plate 14 interlocks with the latch 26. 15, the latch 26 swings to the back side of the front plate 1, and the door can be opened.

E. Function The emergency unlocking device for the coin locker of the present invention is used to replace the lock when the user loses the customer key 19 while the car is locked, and to perform emergency unlocking and re-locking for checking and inspecting stored items for security reasons. Locking is done as follows.

First, the master key 35 kept by the administrator
When the pin 16 is inserted into the master lock 2 and rotated approximately 30 degrees to the right, the actuation plate 9, which rotates integrally with the master lock 2, rotates, causing the pin 16 to engage the rotation prevention plate 1.
2 is vertically pushed down as shown in FIG.

When the rotation prevention plate 12 is pushed down vertically, the customer lock 3 inserted in the lock seat 17
It is released from the square groove 18 of No. 2 and jumps out from the lock seat 17 due to the elastic force of the plate spring 21. In this state, the customer lock 3 can be replaced if the spare key 19 is lost.

Next, in order to emergency unlock the lock while it is locked, when the master key 35 is further rotated to the right from the above state, the pin 16 of the actuating plate 9 moves the swing plate 14 to the fifth position.
It is removed from the recess 15 after being rotated as shown in the figure.

When the swing plate 14 rotates from the state shown in FIG. 4 to the state shown in FIG.
The latch 26, which is integral with the pin 24, is retracted and becomes unlocked.

In addition, to relock after the above-mentioned emergency unlocking,
When the rotation prevention plate 12 is pushed down by operating the master key 35 as described above, the rising claw piece 44 of the rotation prevention plate 12 releases the tension formed at the end of the coin checker 34 as shown in FIG. Push down the ejection piece 43 and insert the coin checker 34 into the coin passage 47 of the machine frame 31 in the same way as when the coin 32 was inserted.
Remove from. In this state, when the master key 35 is rotated in the opposite direction to the above-mentioned emergency unlocking, the swing plate 1
4 rotates from the state shown in FIG. 5 to the state shown in FIG. 4, and as a result, the latch 26 protrudes from the door via the pin 24 and becomes locked. Therefore, the lock can be relocked without inserting a new coin 32.

In addition, when installing and removing from the coin locker,
The mounting block 8 is lowered and removed by rotating the master key 35 to the left and pressing down on the lower surface of the notch groove 10 with the pin 11, while for installation, the master key 35 is rotated to the right and the mounting block 8 is pushed down. Raise it and do it.
