Description

[Detailed description of the invention] The present invention relates to a triple lock suitable for safe deposit box locks, and in particular, the present invention is concerned with attaching a card lock to the door plate of a safe deposit box that is equipped with a customer lock managed by the customer and a bank lock managed by the bank. This is a triple-layered lock that has improved safety.

Generally, locks that require multiple unlocking and unlocking include safe deposit boxes located in banks and the like.

Conventional safe deposit boxes have a bank lock that is unlocked by the bank's safe deposit box staff, and a customer lock that is unlocked by the customer using the safe deposit box. If you wish to do so, please notify the bank representative at the reception department, and both the bank representative and the customer accompany you to the safe deposit box, unlock the bank lock, and then It is said that the lock can be unlocked,
It required extremely cumbersome procedures and collaborative work. Therefore, whenever a large number of customers visit a bank and request the use of the service, a person in charge from the bank must accompany them, which always imposes a labor burden on the bank and affects management costs. One way to reduce this labor burden is to hand over the key to the bank lock to the customer at the reception department, but in many existing safe deposit boxes, all customer locks are combined with different keys. However, bank locks were double-locked with fewer different keys, and if the key to the bank lock was handed over to the customer, there was a risk of safety problems such as loss or duplication. To completely prevent crime, it would be possible to use different keys for all bank locks, but this would tend to cause confusion in key management and increase the labor of the person in charge. In an attempt to solve these problems, a centralized control system was developed in which the bank's reception department uses a computer to unlock and lock the bank lock each time a customer uses the safe deposit box. Regardless of the situation, in the case of an existing safe deposit box, wiring work etc. requires a great deal of expense and effort, and in many cases the modification work itself is difficult.
It was considered impossible to apply this method to the large number of safe deposit box facilities already in use.

The purpose of this invention is to solve the above problems and
A double lock consisting of a customer lock and a bank lock is equipped with a magnetic card lock in which an authentication code is written each time using an encoder in the reception department to create a triple lock, and all bank locks are managed using different keys. , eliminating the need for a bank representative to accompany the customer to the safe deposit box.
Moreover, it is easy to manage cards, and it has a simple configuration that can be installed in existing safe deposit boxes without requiring major construction.We offer a triple lock that is labor-saving, economical, and crime-prevention. .

In order to achieve the above object, the present invention installs a third lock that opens and closes the keyhole of the double lock bank lock provided on the door plate of each safe deposit box with a shutter.
The lock includes an identification means for determining the authentication code of the magnetic card, a sliding member that is unlocked based on the determination result, and a transmission member that links the operation of the sliding member with the opening and closing operation of the shutter. It is characterized by forming a triple lock.

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

FIG. 1 is a diagram showing an example of a triple lock according to the present invention, in which figure A is a plan view, figure B is a front view, and figure C is a perspective view. In the figure, a double lock B consisting of a customer lock and a bank lock is attached to the door plate A of each safe deposit box on the inside of the safe, and the customer lock keyhole B-1 and the bank lock keyhole B-2 are located on the door plate A. The bank lock keyhole B-2 is exposed on the outside and is covered with a third oblong shape.
Lock C is installed. A window C-2 is provided in a portion of the third lock C corresponding to the bank lock keyhole B-2, and is opened and closed by a shutter that slides in the longitudinal direction of the lock. The third lock C is a magnetic card lock, and in this embodiment, an insertion slot C-3 for the magnetic card D is provided on the side surface far from the keyhole B-2. It also depends on the arrangement and the structure of the door or double lock, and is not intended to limit the invention.

The magnetic card D has a rectangular or oval shape similar to a normal authentication card made of laminated magnetic material, and may correspond to the structure and dimensions of the lock C, but the magnetic material may be made of barium ferrite. It is most desirable to use a card D, and not a partial tape like a normal authentication card.
It is enclosed by the sheet plate surface covering almost the entire area.
Barium ferrite has a high magnetic density, good separability, and is easy to polarize, so if it is sealed in the form of a plate, an encoder can set any coordinate point on the plate to the north or south pole. It can be magnetized, and each magnetized point exerts the attraction and repulsion of a magnet.

2 and 3 are cross-sectional views showing a preferred example of a triple lock in which the present invention is implemented.
The main body of the lock, that is, the magnetic card lock, is composed of a base body 1 attached to a door plate A, and a cover body 2 fixed to the base body 1. The base body 1 occupies a horizontally elongated part of the surface of the door plate including the bank lock keyhole B-2, and a window 11 having a size that sufficiently exposes the bank lock keyhole B-2 is opened.

The cover 2 is a horizontally elongated hollow trapezoidal cube formed by bending a metal plate and has dimensions that cover all of the base 1 described above. Same as 1, bank lock keyhole B-2
A window 21 is opened at a position corresponding to . The window 21 portion of the cover 2 is made thinner by forming a step on the top surface of the trapezoid so that the bank lock key can be easily operated, and within the step, a space shutter sandwiched between the windows 11 and 21 is formed. 3 opens and closes. Further, an insertion slot 20 for a magnetic card D is provided on the side surface of the end portion of the cover body 2 opposite to the stepped portion.

A storage plate surface 12 for holding the magnetic card D inserted into the cover body 2 is fixed to the base body 1 in parallel with the door plate surface, and a magnetic pin 13 is loosely fitted approximately perpendicular to the plate surface. There is. This magnetic pin 1
The N-S polarity of No. 3 and the coordinate position on the storage board surface are different authentication codes for each safe square, and the storage board surface 12 and the magnet pin 13 constitute identification means for the stored magnetic card. Magnetic pin 1
3 is supported by the housing plate surface 12 via a spring 14, and the sliding member 1 is supported by the slight pressure of the spring 14.
It is lightly pressed against 5. An engagement hole 15a is bored in the sliding member 15 at a coordinate position corresponding to the magnetic pin 13, and when the sliding member 15 reaches a predetermined locking position, the magnetic pin 13
One end of the slide member engages with this engagement hole 15a, and the sliding member is locked. Magnetic card D is inserted,
If the polarity and coordinate position of the magnetic card assigned by the encoder in the reception department match the authentication code of the safe box, the magnetic pin 13 is pulled out from the engagement hole 15a by the magnetic force of the barium ferrite and slid. The moving member 15 is unlocked. The sliding member 15 includes a protruding wall 15b that comes into contact with the insertion edge of the magnetic card D, and when the magnetic card D is further pushed in after being unlocked, the sliding member 15 also moves in conjunction with the movement of the magnetic card D. It leaves the locked position and slides along the longitudinal direction of the base 1 toward the lock hole. On the other hand, the transmission member is a lever 16 in which pin holes are provided at both ends and in the middle of a band-shaped metal plate, and a support shaft 16a protruding from the base body 1 is loosely inserted into the pin hole in the middle to serve as a fulcrum. , said sliding member 15 via a pin 16b at one end.
The shutters 3 are moored to the other ends of the shutters 3 in a slidable manner via pins 16c. Therefore, the operation of the sliding member 15 is linked to the opening and closing of the shutter by the raising and lowering operation of the lever 16, which is a transmission member, but the sliding direction is reversed.

That is, when the magnetic card D is pushed in, the shutter 3 slides in the opening direction. In the sliding stroke, the stopper may be provided anywhere, but in this embodiment, the protruding wall 15b of the sliding member 15 is located at the base 1.
It comes into contact with the stopper wall 18 and stops. Note that the lever 16 in this embodiment is operated by a spring 17.
If the shutter 3 is biased in the closing direction and the magnetic card D is not pressed down, the shutter 3 will close.
The sliding member 15 returns to the locked position and is locked onto the magnetic pin 13.

Next, the operation of the above lock will be explained.

The customer requests the use of the safe deposit box at the bank's reception department, receives a double-locked bank lock key and a magnetized encoded magnetic card, and goes to the safe deposit box. Bank representatives do not go to the site.

The customer first inserts the magnetic card into the insertion slot of the cover. When the polarity and coordinate position of the magnetic card match those of the safe box, the magnetic pin is pulled out from the engagement hole and the sliding member is unlocked, so that the magnetic card is further pushed in and the shutter is moved. FIG. 4 is a sectional view showing a state in which the shutter is opened in this embodiment. In the figure, the sliding member 15 moves toward the keyhole, and the lever 16 is raised and lowered to move the shutter 3 in the opposite direction to the keyhole, exposing the keyhole B-2 of the bank lock.

The customer inserts the bank lock key handed to him by the reception department into keyhole B-2 to unlock it, then inserts his own customer lock key into keyhole B-1 of the customer lock to unlock it, and then closes the door plate. Open and use the safe deposit box.

When the use of the safe deposit box is finished, the customer closes the door plate,
When the customer lock and bank lock are locked and the bank key is removed, the shutter is closed and locked by the biasing force of the spring.

Some double locks allow you to remove the bank key immediately after unlocking the customer lock. In such a case, if you remove the bank key and magnetic card, the entire triple lock will be locked the moment you lock the customer lock, and from a security standpoint, this operating procedure is recommended. .

Finally, the customer returns the bank lock key and magnetic card to the bank's reception department to complete the procedure. Both the bank lock key and the magnetic card are lent only within the bank, so the risk of losing them is extremely low. However, even if the bank lock key is lost or duplicated, the magnetic card has a different key for each safe space, so it cannot be used. Since the code is encoded each time the lock is encoded, the security of the lock is maintained sufficiently.
In addition, the contents of magnetic cards should be demagnetized after use.
Since it can be used any number of times for the next customer, only a small number of sheets need to be stored and management is easy.

In addition, the arrangement of each member of the present invention can be moved point-symmetrically, line-symmetrically, or plane-symmetrically, depending on the positional relationship between the customer lock keyhole and bank lock keyhole, where on the door plate the double lock is attached, etc. Although some ideas may be considered, none of them are exempt from the scope of claims for registration of the present invention.

As explained above, the triple lock of the present invention uses magnetic force and is constructed with simple equipment, and does not use electricity, so there is no need for large-scale wiring work, but it does not require encoding of the authentication code. The same effect can be achieved by using a magnetic card managed by a computer, and since the authentication code is different-keyed for all the safe boxes, there is no need for a bank representative to accompany the safe deposit box. There is no need to even replace batteries, it is easy to manage, simple to operate, and has a simple structure.This invention can be applied to existing safe deposit boxes by simply attaching a magnetic card lock to a double lock consisting of a customer lock and a bank lock. It can be made into a triple tablet. That is, the present invention provides a triple lock that saves labor, is economical, and has crime prevention effects.
