Description

DOOR LOCKING DEVICE FOR PRIVATE CASHBOX}

This invention is designed to be used as a part of customer service by banks, insurance companies, securities companies, financial institutions, etc., to store important documents and valuables for each customer, and to open the secret lock of the customer only when the customer wants. The present invention relates to a door lock device for a secret locker, and more particularly, to a secret locker door lock device, which focuses on the improvement of manufacturability, volume reduction, and ease of operation according to the security of an opening gate and the simplification of structure.

In Fig. 1, a locking device 2 is attached to the rear surface of the free end side of the door 1 installed in the secret locker of the conventional secret safe, and the limit switch 3 mounted in the locking device 2 has a terminal casing ( Exposed to the back side of 4). When the limit switch 3 is closed, it touches the front of the drawer 5 to be pressed and turned off. When the door is opened, the electrical signal is sent to the secret vault management computer so that the secret lock number, opening date, opening time, and opening door are opened. It is useful as a tentacle to operate a system in which time and closing time are automatically recorded.

Since the door lock of the secret locker for the secret locker is equipped with a limit switch to contact the drawer in the secret locker, even if the appearance of the casing is insignificant, even if it is unlocked, the opening time information cannot be accurately recorded in the record.

Even more worrying is that the limit switch is exposed outside the casing, so if you open the door quickly and turn off the limit switch by hand, there is no information related to the secret locker, and there is a high possibility of being exploited by an intruder who is dishonest. to be.

Therefore, the purpose of the present invention is to ensure the safety that can be recorded at any time the information related to the use of the secret lock on the computer.

The present invention completely hides the limit switch in the casing, which emits an electrical signal that is the beginning of all information related to the secret locker such as opening date, opening time, opening time, closing time, etc. This is a secret safe box mounted in a safe place inside the casing to turn on and off simultaneously with the locking and unlocking operation.

In Fig. 2, a clamp 6 that hides and releases and pops out in accordance with the operation direction of the key in the casing 4, and a plurality of unlocking levers 7 for retaining the clamp 6 in a locked state, the secret from the outside. The master key or bundle of secret lockers (8) for safekeeping, the reverse width of the key bundle (8) during reverse operation of the key, and the lock release lever (7) and the same number of reverse stop levers (9), opening and closing. Circuit board 10 for signal transmission, a stop lever 12 for inverting and closing the door in an openable state and a solenoid 11 for operating the stop lever 12, and an LED 13 for informing that the door is openable. And a cover 14 and a lever-type stopper 15 for stopping the catch 6 so as not to rewind freely unless the door is closed in the unlocked state.

The key (8) can be operated with the correct key so that the groove (7a) of all the deterrent paper levers (7) is in line with the wing (6b) so that the wing (6b) can enter the groove (7a). Therefore, it is possible to release the clamp 6 only.

In FIG. 3, a locking groove 6a is formed at the rear surface of the front end of the clamp 6, and a locking protrusion 15a is formed at the inner end of the clamp stopper 15 when the locking groove 6a coincides with the approach. Formed. This figure shows when it is in a ruled state.

In Fig. 4, the solenoid 11 is energized and the stop lever 12 is pivoted to release the catch of the rear end of the stop lever [] 2 which has been engaged with the projection 6c protruding from the rear end of the clamp 6. When the key is inserted into the key bundle 8 and operated in the unlocking direction, the catch 6 is hidden into the casing 4.

In FIG. 5, the clamp stopper 15, which is waiting for the lock groove 6a of the clamp 6 at this time, is turned counterclockwise in the figure by the spring 16 so that the locking protrusion 15a is locked. The unlocked state is locked by crawling into 6a.

The clamping stopper 15, which is pressurized by the door 1 closing in the direction of the arrow D ₁ , turns counterclockwise as shown in the figure, whereby the catch 6 when the catching protrusion 15a is out of the locking groove 6a. It is possible to advance (rule). This is known so far.

In FIGS. 3 and 6, the limit switch 3 is moved further away from the rear end of the clamp 6. As a result, the terminal switch for the limit switch, which has been drilled on the back surface of the casing 4, does not need to be drilled, thereby reducing the man-hour.

Between the clamp 6 and the limit switch 3, there is provided a slider 17 for pushing and turning on the terminal 3a of the limit switch 3 by a linear motion when the clamp 6 is released. At the rear of 17), the return spring 18 is loaded to return the slider 17 when the clamp 6 is locked so that the limit switch 3 can be turned off.

The computer in which the secret safe management operation program not shown is inputted, the password of the secret locker for each customer. Let's give an example of a secret box secret locker management program. When the owner of the secret locker appears and asks the secret box manager to use the secret box, the vault manager displays the related program on the monitor. The box for the safe deposit box will appear on the monitor. If you enter your own fields, you will be prompted to enter a password. Accordingly, the customer enters his password. If the passwords match exactly, an electrical signal is applied to the solenoid 11 and the LED 13 of the secret lock corresponding to the password. The solenoid 11 moves the stop lever 12 to release the lock on the clamp 6, and the LED 13 emits light to indicate the position of the secret lock to the outside.

When the customer finds his secret locker, he opens his door (1) by inserting his key into the key (8). When the catch 6 is released, the slider 17 is pushed back, and the slider 17 is turned on by pushing the terminal 3a of the limit switch 3. From this time, the use date, opening time, and opening time of the secret locker are displayed. Is written on.

Even if the door 1 is opened, the limit switch 3 cannot be touched outside the door at all.

This is because it is not hidden by the casing 4. Therefore, even if it is illegally opened by a third party, it is impossible to change the opening date, opening time, opening time or recording such information on the computer. So the security of secret lockers is further strengthened.

In the state in which the clamp 6 is released, the locking groove 6a approaches the locking projection 15a of the clamp stopper 15, so that it is not locked even when the key is reversed (see FIG. 5).

Close the door (1) after you have finished using your secret locker. When the door 1 is closed, the stopper 15a is pushed back by pressing the stopper 15 against the door holder, and the locking projection 15a is released from the locking groove 6a. At this time, when the key is reversed, the catch 6 is locked. As the catch 6 is tightened, the slider 17 is returned by the return spring 18. With the return of the slider 17, the limit switch 3 is turned off and the solenoid 11 is cut off to stop the ram by returning. The lever 12 is also pivoted back to lock the projection 6c formed at the rear of the clamp 6 which is locked again, and locks it freely so as to be freed, and the recording on the computer is also stopped there.

The secret lock door lock device of the present invention described above can be further enhanced by hiding a limit switch in the casing, which is turned on at the same time as the door and turned off at the same time, to prevent external touch.

In addition, since the information related to the use of the secret locker is recorded on the computer through the limit switch at the same time as the unlocking and locking of the lock, the recording error is hardly generated and the recording reliability is very high.

In addition, since the terminal hole of the limit switch is not drilled on the back side of the casing, the side effect is reduced and the appearance is improved.
