Description

[Detailed description of the invention] [Industrial application field] The present invention relates to safe deposit box locks, and in particular, the invention adds an outer lock that covers the existing customer lock and bank lock, and locks the outer lock with a magnetic card. The present invention relates to a safe deposit box lock that not only locks, but also locks and unlocks the existing bank lock in conjunction with the locking/unlocking operation.

[Conventional technology]

In general, safe deposit box locks consist of bank locks, which are locked and unlocked by the bank's safe deposit box personnel, and customer locks, which are locked and unlocked by each customer who uses the safe deposit box by keeping a different key. If you wish to use a safe deposit box, please notify the bank staff at the reception desk, and both the bank staff and the customer will accompany you to the safe deposit box and unlock the bank. Unlocking the customer's lock and opening the door of the safe deposit box required an extremely cumbersome procedure and collaborative work. For this reason, banks are burdened with the labor burden of having to send a person in charge to accompany a large number of customers each time they request the use of a safe deposit box, which greatly affects management costs. Therefore, as an improvement on this, a centralized control system was developed in which the bank's reception department uses a computer to lock and unlock the bank lock each time a customer uses the safe deposit box. In addition to requiring a large amount of time and expense, in the case of existing safety deposit boxes, it is often difficult to modify them, and it has been considered impossible to apply this method to the large number of facilities already in use.

[Problem that the invention attempts to solve]

The problem that this invention aims to solve is that by simply using old locks that are already in use and adding a simple management lock to them, new locks can be created that do not require bank personnel to accompany the customer. The goal is to find the possibility of safe deposit box locks. The present applicant has already proposed, in Utility Application No. 58-164357, an improvement to the old locks in which the door plate is penetrated by customer locks and bank locks, which are locked and unlocked by inserting a key into the keyhole and turning it. However,
In this system, the customer side of the old lock was controlled by an external lock, and the bank lock was supposed to be kept unlocked, and if it was not held securely, there was a risk of malfunction. In view of the above, the present invention has a device configuration that can be easily installed in existing safe deposit boxes without requiring major construction work, which allows banks to fully manage the equipment, and which reduces the risk of malfunctions. The purpose is to provide safe locks.

[Means for solving problems]

In this invention, the means to solve the above problem is to cover the keyholes of the customer lock and bank lock installed in the door plate of each safe deposit box with an external lock, and use an encoder in the reception department to authenticate the keyhole. The sliding movement of the cover body of the outer lock is locked and unlocked using the magnetic card key written with the information, and it is determined whether the customer lock keyhole is exposed or not. This is a safe deposit box lock equipped with a transmission member that is linked to the unlocking operation.

[Effect]

The magnetic card key used in the present invention may have a rectangular or oval shape similar to a normal authentication card made of laminated magnetic material, as long as it corresponds to the structure and dimensions of the outer lock. However, it is most desirable to use barium ferrite as the magnetic material, and instead of using a partial tape-like magnetic material as in a normal authentication card, the magnetic material is encapsulated in a sheet plate covering almost the entire area of the card. Barium ferrite has a high magnetic density, good separability, and is easy to polarize, so if you enclose it in the form of a plate, an encoder will magnetize any coordinate point on the plate to N or S pole. Each magnetized point directly exerts the attractive force and repulsive force of a magnet.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to embodiments and drawings.

FIG. 1 is a sectional view showing an example of an outer lock embodying the present invention. In Fig. 1, a door lock L is attached to the door plate D of each safe deposit box, and a normal safe deposit box consists of a double lock consisting of a customer lock and a bank lock, and each lock hole A and B is the door plate D
It is installed through the. The outer lock C is attached by covering the two lock holes A and B, and the outer lock base 1, which is formed by a rectangular plate punched through a keyhole window, is fixed to the door plate D, and the outer lock cover is fixed to the door plate D. The body 2 is fitted onto the base body 1 so as to be slidable in its longitudinal direction. The lid body 2 is a hollow trapezoidal body with an open bottom surface, and the base body 1 supplements the bottom surface, and an insertion slot 20 for a magnetic card E is provided on the side of the trapezoidal body farthest from the keyhole A of the passenger lock. ing. FIG. 1 shows a state in which a magnetic card E is inserted, and a storage plate surface 12 for sandwiching the magnetic card is fixed to the base body 1 in parallel with the door plate surface, and holds the magnetic card E. . A magnetic pin 13 is loosely fitted almost orthogonally to this storage plate surface 12, and the N-S polarity of this magnet pin 13 and the coordinate position on the storage plate surface are different password codes for each safe deposit box square. The plate surface 12 and the magnetic pin 13 constitute means for identifying the stored magnetic card. Magnet pin 13 is spring 1
4 on the storage plate surface 12, and is lightly pressed against the sliding lever 15 by the slight pressure of the spring 14. . The sliding lever 15 has an inner plate 15
a and the outer plate 15b are made parallel to each other and connected by a connecting plate 15c at the edges in the same direction, so that they are integrally formed in a U-shaped cross section, the inner plate 15a is in contact with the storage plate surface 12, and the outer plate 15b is connected to the lid body. It is in contact with 2. An engagement hole 15d is bored in the inner plate 15a at a coordinate position corresponding to the magnet pin 13, and when the sliding lever 15 is at a predetermined locking position, one end of the magnet pin 13 is inserted into the engagement hole 15d. The movement of the sliding lever 15 is locked. When the magnetic card E is inserted and its polarity and coordinate position match the authentication code of the safe deposit box, the magnetic pin 13 is pulled out from the engagement hole 15d by the magnetic force of the barium ferrite, and the sliding lever 15 is unlocked. On the other hand, a pair of pillars 17 are planted in the base 1, and the pillars 17
A shaft 18 is installed between the ends of the shaft 18, and a rotating lever 16 that rotates around the shaft 18 is attached. The rotating lever 16 is integrally formed with a pair of arms 16a attached to a shaft 18 and an engagement plate 16b spanning between the ends of the arms, and is suspended between the engagement plate 16a and the shaft 18. The provided spring 19 constantly biases the engagement plate 16b in the rotating direction to press it against the lid body 2, but at the same time, the slope portion 16b' of the engagement plate 16b is pushed against the outside of the sliding lever. It is in sliding contact with the slope portion 15b' of the plate 15b, and rotates in the direction of separating from the lid body 2 against the force of the spring 19 in conjunction with the movement of the sliding lever 15 from the locking position. The inner wall 21 of the trapezoidal top surface of the lid body 2 has a ridge 2.
2 is formed, and when the lid body 2 is in the locked position, it engages with the engagement plate 16b of the rotary lever to lock the sliding movement of the lid body 2. If the authentication code of the inserted magnetic card E is compatible and the magnetic pin 13 is pulled out, when the magnetic card E is further pushed in, the leading edge of the magnetic card E will touch the drive plate 15.
e to move the sliding lever 15 connected to the drive plate 15e from the locking position. Due to this movement, as already explained, the engagement plate 16b of the rotary lever 16 separates from the protrusion 22 of the lid, and the lid 2
is unlocked and can be slid. The sliding lever 15 and the rotating lever 16 described above constitute the locking means of the present invention.

The external lock of the present invention functions as a management lock using the above-mentioned identification means and locking means, and this function is performed in two ways. One is to expose or cover the keyhole A of the customer lock, and Figure 1 shows the lid in the cover position.
When the lid 2 is unlocked by the magnetic card key E and slid to the right in the figure, it is in the exposed position shown in FIG.
The customer is allowed to unlock the customer key by inserting his or her own customer key into the customer lock keyhole A exposed through the keyhole window 11 of the customer. The other method is to link this sliding motion with the unlocking of the bank lock through a transmission means, and the present invention implements this based on the rack and pinion principle. The broken part in FIG. 1B is a sectional view showing an example of the transmission means, and FIG. 2 is a sectional view taken along Y--Y' in FIG. 1B. In both figures, a pinion 3 is attached to the bank lock keyhole B exposed through the keyhole window 11' of the base 1 by a fixing method described later.
On the other hand, a plate-shaped rack 23 is erected from the inner wall 21 of the trapezoidal top surface of the lid body 2 toward the base body 1, and the above-mentioned It meshes with pinion 3. Pinion 3 is
The rotation shaft 31 is pivotally supported by the base 1 via the support wall 17a, and the rack 23 is fixed to the lid 2, so when the lid 2 slides on the base 1, the movement is As shown in Figure 4 A and B, rack 23
This is converted into a rotating motion by the pinion 3, and the bank lock is locked. Here, the covered position of the lid body and the locked position of the bank lock are made to correspond, for example, in the state shown in Figure A, and the exposed position of the lid body and the unlocked position of the bank lock are made to correspond, for example, in the state shown in Figure B. If you respond with
Two functions are accomplished in one operation.

In this embodiment, the bank lock is unlocked by inserting a key into the keyhole and rotating the key, and the connector connecting the bank lock and the pinion is the bank lock key. The insertion part is of the same type as the insertion end of the keyhole, and the insertion part is inserted into the keyhole to engage the bank lock, and the part corresponding to the key handle is shaped to protrude from the keyhole. . FIG. 5 is a perspective view showing an example of a transmission means implementing the present invention, and in the figure, door plate D
The protruding part 4b of the connector protruding from the keyhole of the bank lock B exposed in the figure is shaped like a plate, and the receiving hole 3b bored in the pinion 3 corresponds in shape and size to the protruding part 4b. is fitted and fixed. A tooth profile 23a is carved on the edge of the rack 23, and the tooth profile 23a meshes with the gear 3a of the pinion 3 when the lid is fitted onto the base body.

When the safe deposit box lock according to the present invention is adopted, for example, the following two usage methods can be selected.
If you want to manage the external lock as a pure bank lock, you can create a system where the reception department encodes and issues a magnetic card key and the customer collects it after using the safe deposit box.
Just give the encoded magnetic card key to the customer like a cash card at the time of signing the contract. Further, this magnetic card key may be used for inputting information into a time coder to manage information, and it can also be used for room entry/exit management in the same way as a general magnetic card.

It should be noted that the authentication code does not necessarily have to be different for each customer or safe deposit box, but if it is unified for each row, branch, etc., apart from security warrants, it will be a little easier in terms of equipment, and it will be easier to use as a bank lock. It performs a minimal function and is more convenient than connecting the sliding movement to the passenger lock. In addition, with this invention, each time the outer lock is locked and unlocked, the inner bank lock is also locked and unlocked, so it is the same as checking the condition of the bank lock each time, and failures may occur. Even in the event of a failure in unlocking due to misadjustment of the tumbler of the door lock, which tends to occur after long-term use, it is possible to make a natural adjustment by repeating the sliding movement of the outer lock.

[Effect of idea]

As explained above, according to the present invention, it has a simple equipment configuration that can be easily installed in existing equipment, has the function of a bank lock that can be managed without the need for a bank representative to accompany the safety deposit box equipment, and prevents failures. It is possible to provide a convenient, low-cost safe deposit box lock with little fear of occurrence.
