Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an unlocking method that includes a plurality of locks and performs double unlocking.

Generally, locks that require double locking and unlocking include money lending bits installed in banks and the like.

The above-mentioned conventional safe deposit box is equipped with a bank lock that is unlocked by the person in charge of the bank, and a customer lock that is unlocked by the customer who uses the safe deposit box. When using a bank, both the bank's person in charge of loan 1 and 1 and the customer who requested the use accompany the customer to the location of the customer's safe deposit box, which is under a usage contract, and first lock the bank. After unlocking the bank, the customer's lock was unlocked, a cumbersome procedure that required the joint effort of both parties to fully unlock the bank. Each time the bank uses the safe deposit box, the person in charge of the bank's safe deposit box accompanies the bank, which poses a problem in that the bank is always burdened with labor and the cost of using the bank increases.

In addition, as an improvement on this, by centrally managing safe deposit box equipment using computers, I+
7r! This is a labor-saving system that allows the bank's safe deposit box staff to perform the unlocking operation of the bank lock each time a customer uses Money Loan i City at the bank's reception department, without having to go to the customer's safe deposit box location. Safe deposit box facilities have already been developed. However, since this method is carried out by centralized computer control, it is necessary to conduct wiring work to communicate with the reception department for each square of the existing safe deposit box (each customer's deposit 14f). Therefore, the installation work requires a lot of labor and time, and the above-mentioned wiring reduces the space of each square by that much, and leakage of electricity in the wiring can cause severe damage to valuable items inside the safe deposit box. There was a problem in that the safe deposit boxes were not able to fulfill their mission of maintaining the original condition of storage due to the danger involved.

This invention was made to solve the above problems, and its purpose is to close the customer keyhole provided in each square of a safe deposit box with a bank lock, etc. By lending an unlocking unit for a safe deposit box, etc., which is equivalent to a bank lock, to a customer, the bookkeeper or the like can unlock it with the above-mentioned unlocking unit without having to go all the way to the customer's safe deposit box, resulting in labor savings. In addition to achieving a low cost for use in safe deposit boxes, etc., there is no need for wiring work inside the H money car etc. (=Therefore, without reducing the space of the safe and ensuring safety against fire ,
It is an object of the present invention to provide an unlocking method that also provides a crime prevention effect by causing the unlocking unit to lose its resolving power over time.

The present invention will be explained below with reference to the accompanying drawings.

First, the safe deposit box lock, which is the basis of the unlocking method according to the present invention, is constructed as follows. In other words, as shown in Figures 1 and 2, the amount of money ni (
A large number of squares A are arranged in a stacked manner, and on the front part of each square A, a safe deposit box lock C for each six squares is installed on one side of the back surface, and this lock C is installed on the front surface. In a money lending ff1f facility in which a door plate B is provided with a keyhole for the first customer to open and close by unlocking, as shown in FIGS. 2 to 5, The surface containing the customer keyhole has the following (2) lock body 1
is permanently attached. The main body 1 of the lock R11 is entirely formed of a metal plate into a horizontally elongated shape. One side, which matches the customer keyhole, has a thin hollow space inside, and a vertically elongated window 1a is provided on the front surface thereof. Further, on the right side of this, there is provided a cover part 1b whose interior becomes a hollow space in the original shape. Further, on the right side thereof, there is provided a locking chamber 1c which has a horizontally elongated shell shape and has an open middle band on the front and an upper band on the other side.

A recess 1d into which a protrusion 11b of a cassette 11 (to be described later) can be inserted for 11 minutes is provided at approximately the middle of the upper vertical surface of the front side of the lock chamber 1c.

At the inner bottom of the bank lock chamber 1c, a platform 2 having a volume that can fit 11 minutes over the entire inner bottom is fitted. On the flat surface of the base section 2 other than both ends, there are magnets arranged at the same intervals as the electromagnets 15 in the cassette 11, which will be described later.
A vertical hole 2a with two rows of six rows is provided extending all the way to the bottom. Each vertical hole 2a has a spring 13 on the bottom side, and its supporting force causes the upper end of the hole 2a to
A round bar-shaped magnet 12 that is formed to protrude from inside a is placed in two ways within the hole at each position: one where the upper end is the N pole, and one where the upper end is the S pole. It is arranged so that it can be moved up and down as a lock body for a bank lock.

Next, a vertical surface is provided at the top surface of the platform 2, and
In addition, in the horizontal plane connected to this vertical plane, each of the above-mentioned vertical holes 2a is provided.
A lock plate 3 having a hole 3a concentric with the lock plate 3 is mounted so as to be slidable in the left and right direction. And this lock plate 3 is
Close to the lower end of the lever 6, which is arranged so as to be able to be raised and lowered in the left and right direction by fitting the lowermost end hole with respect to the support shaft 7 that protrudes forward from the inner longitudinal surface of the cover part 1b. At the pin hole position, a pin 8 is loosely inserted into the elongated hole in the vertical plane and is fixed so as to be integrally slidable from side to side. Note that this lever 6 has similar bottle holes on the upper end surface and the midway surface (
It's been 10 years.

Further, a cassette guide 4 shown below is housed in the lock chamber lc so as to be slidable left and right. The cassette guide 4 has a vertical surface on the -1 side, and the other side has a U-shaped cross section that can be loosely fitted into the locking chamber lc. This cassette guide 4 has a pin 9 loosely inserted into the elongated hole on the Y side of the lever 6 in the middle position of the lever 6, so that when the cassette guide 4 slides left and right, the lever 6 can It has been shot down as likely as possible.

Furthermore, a shutter 5 is fitted within the window portion 1a of the lock main body 1 so as to be slidable left and right. And this shutter 5
1. Drunkenness. - By inserting the bottle 10 loosely into the bottle hole provided at L of the self-lever 6 and integrally accompanying the raising/lowering operation of the lever 6, the keyhole for the customer at the window 1a position is installed. The missiles are pinned down to allow for exposure and cover.

Furthermore, a cassette 11 shown below is fitted into the Arl bank lock chamber IC so as to be detachable and slidable in the left and right directions. This cassette 11 has a planar body formed in a convex shape. A dowel hole 11a corresponding to the dowel 4a of the cassette guide 4 described above is provided on one side of the front surface. Further, a convex portion 11b is provided on the upper surface to allow passage through the concave portion 1d of the lock chamber IC. Next, electromagnets 1 are placed on the bottom surface of the cassette 11 and are excited by the internal ``junior'' 1014 at positions corresponding to the magnets 12 described above.
5 is included.

Each of the electromagnets 15 described above is formed by double windings 15a and 15b so that the magnetic field can be changed.

The magnetic field can be changed by changing the output signals of two AND circuits 16 and 17 connected to the double windings 15a and 15b, respectively, as shown in part in FIG. ing. One end of each input of the AND circuits 16 and 17 is connected via a reset line 20 to one end of a timer 19 housed in the cassette 11. The other end of each input of the AND circuits 16 and 17 is connected to the output of the flip-flop 18 for each position. Each input terminal of this flip-flop 18 is
An encoder 24 (-, which will be described later) is formed so that it can be removably connected via a connector 23.Furthermore, at the other end of the timer 19, an encoder 24 (which will be described later) is connected.
Therefore, by limiting the pulse transmission from the above AND circuits 16 and 17 to the electromagnet 15 at each position by the code signal of the magnetic field setting within a specified desired time, the above pulse transmission disappears over time. A timer reset line 21 is connected to set the time. Furthermore, a clock pulse line 22 is connected to each flip-flop 18 described above from an encoder 24, which will be described later. The lock 11 formed in this manner becomes an unlocking body for a bank lock.

The encoder 24 schematically shown in FIG. 7 has 12 combinations of magnets 12 set for each safe deposit box A, that is, 12 magnets 12 in total, with the upper end set to the N pole for each position. There are two types of classification: those that are at the S pole, and those that are at the S pole.

Since there are 2+2 = 4,096 combinations, unique lock combination codes set within this range 1 are recorded. Then, this unique code is sent to the cassette 1 through the connector 23.
One flip-flop 18 is commanded with a pulse signal, thereby making it possible to apply a full magnetic field to each electromagnet 15 having the same polarity as the magnet 12 immediately below it.

The operation of the safe lock of the present invention according to the above embodiment will be explained.

The money lending lock is locked in advance as follows.

That is, as shown in FIG. 3 and one side of the fourth Iyl, when the aforementioned cassette guide 4 is manually moved to the left, the lever 6 whose left end vertical surface is held by the pin 9 also moves to the support shaft 7. The shutter 5, which is held on the upper end surface of the lever 6 via the bottle 1o, moves while falling in the same direction with the lever 6 as a fulcrum.
It moves sideways in a cooperative manner to completely cover the customer keyhole located within this window portion 1a. At this time, due to the leftward movement and fall of the lever 6, the locking plate 3, which is held near the lower end of the lever 6 via the bottle 8, also moves to the left at the same time, so that each of the locking plates 3 Hole 3
a coincides concentrically with the vertical hole 2a of the platform 2.

Therefore, the magnet 1 fitted in each vertical hole 2a
2 is supported by a spring 13 from below and passes through the hole 3a at each position and rises to a height position where it abuts the bottom surface of the cassette guide 4. As a result, the bank lock of the safe deposit box lock is completely locked in the manner in which it protrudes into each hole 3a. (See Figure 6 (a)) If the customer next visits the bank and wants to use the safe deposit box under contract, he/she should go to the reception desk in charge of the bank's wage 11 yen and request the unique number of the contracted safe deposit box. Then, the encoder 24 installed in advance in this reception department gives an unlocking code signal corresponding to the locking combination code recorded with a unique number to the cassette 11 that is always kept in this department. In other words, for each electromagnet 15 housed in the cassette 11 in the same number and arrangement as each magnet 12, the number of poles at each position is the same as that of each magnet 12 that becomes the lock body of the bank lock in the customer's safe deposit box lock. By sending a code signal to the flip-flop 18, the electromagnet 15 at each position is set so that it can be energized by the dry battery 14 and maintain its commanded polarity by transferring the stored signal. There is.

To explain this with reference to FIG. 7, when an input comes to the left side of each flip-flop 18, an output is generated to the AND circuit at the upper left, and a signal of "1" is stored. This stored "1" will continue to be output at the upper left even if there is no longer an input at the lower left.

As a result of the above, the flip-flop 18 at the position 15A in FIG.
is "1 left, O right", indicating that "1" is stored.

In addition, the flip-flop 18 at the 15B position is “left 0,
Since it is "1" on the right, it shows that "0" is written as "1". Furthermore, the flip-flop 18 at the second 15L position is similar to the flip-flop at the 15A position.
1" indicates that the car is stored. Therefore, electricity is applied to the reset line 20 via the timer 19) (/res ``1''
”, the input of the AND circuit 16 at the 15A position becomes “1.1”. As a result, the above pulse is sent to the single-potency coil of the electromagnet 15 with the double winding at the 15A position, and the upper end of this coil becomes the N pole and the lower end becomes the S pole.
In the case of a winding configuration that becomes a pole, the electromagnet 15 at the 15A position is controlled by the timer 19 and continues to be excited by this magnetic field with the throat force supplied from the battery 14, according to the principle of memory signal transfer described in Ail. be able to.

Note that in a corner stand where a pulse is sent to the other side coil of the electromagnet 15 according to the same principle, the magnetic field of this d magnet 15 is changed to the opposite position. In this way, the encoder 24 applies a magnetic field to all the electromagnets 15 so that they have the same polarity as the magnet 12 at each position in the safe-deposit box.

In addition, each flip-flop 18 by the encoder 24
At the same time, the timer 19 is activated when the code signal is acquired for
, the limited usage time is within the range stipulated by the bank.
It is applied via the timer reset line 21.

The customer, who was lent the cassette 11 in which the necessary information was recorded as described above, by the safe deposit box holder of the bank, takes this cassette 11 to the money lending room 147.

After entering the room, when the above-mentioned cassette 11 is inserted into the bank lock chamber IC of the safe deposit box A under the usage contract with the orientation shown in FIG. 2, the convex portion 11b of this cassette 11
is inserted into the chamber 1C through the recess 1d. At this time, at the same time, the dowel hole 11a of the cassette 11 is
is fitted into the dowel 4a of the cassette guide 4. This dowel 4
a serves as a guide for setting the prescribed position of the cassette 11 within the chamber IC. Therefore, the cassette 11 can be accurately inserted into a fixed position within the chamber IC.

When the cassette 11 is inserted into the fixed position in the lock chamber IC as described above, the cassette 11 is inserted into each vertical hole 2a of the base section 2 directly below the cassette 11.
Each red sea bream 12, which is housed with the supporting force of the spring 13, had risen in a protruding shape from the vertical hole 2a into the concentric hole 3a of the locking plate 3, which is located directly above the vertical hole 2a, until the first one (ζ). However, at the same time as the cassette 11 is inserted,
Each magnet 12 has an electromagnet 1 inside this cassette 11.
Anti-r! with the magnetic force of homopolar excitation due to 5! ! In order to be
They will all descend to a predetermined position all at once. Therefore, the locking plate 3, which had been completely locked by the magnet 12, is completely unraveled by the downward movement of the magnet 12 at each position from within each hole 3a, and the bank lock at this position is automatically unlocked. It can be unlocked automatically.

(See FIG. 6 Tb)) Other cassettes 11 to which a code signal different from the code signal of the locking combination of the safe deposit box
In the case where the liquid is injected into the lock chamber 1c, the bank lock cannot be unlocked as described above because no homopolar repulsion is achieved. (See Figure 6 (cl)) When the cassette 11 is slid to the right at the time of unlocking as described above, the cassette guide 4, which is engaged with this cassette 11 via the dowel 4a described in MiJ, is also moved at the same time. They will move to the same location and in the same direction. Therefore, the lever 6, which is connected to the guide 4 via the pin 9, also moves upright in the same direction using the support shaft 7 as a fulcrum. At this time, as the lever 6 moves upright, the lock plate 3 moored near the lower end of this lever 6 via a bottle 8 simultaneously moves to the right, and the lock plate 3 is also moored to the upper end of this lever 6 via a bottle 10. Shutter 5 is moored to
will also move to the right at the same time. As a result, the window portion 1a of the lock main body 1, which had been blocked by the shutter 5 until just before, is completely demolished. Therefore, a new customer lock can be inserted into the customer keyhole.

Note that when the bank lock is unlocked as described above (2. The lock plate 3 also moves to the right and each hole 3a is moved to the right of the position of the vertical hole 2a that was originally aligned when the bank lock was locked. However, since the locking plate 3 is moored near the lower end of the lever 6 and moves less than the cassette guide 4, it cannot reach the vertical hole 2a adjacent to the locking plate 3 in the moving direction. This makes it possible to reliably prevent a bank lock from being accidentally relocked once it has been unlocked by the amount of movement when the shutter 5 is opened.

By unlocking the bank lock as described above, safe deposit box lock C can be unlocked with the customer's own lock inserted through the customer keyhole.
The safe deposit box space A inside the door 13jB can be opened and used.

Furthermore, when the use of safe deposit box square A is completed, when the cassette 11 that had been moved to the right in front of it is returned to its original position as shown in Figs. 3 and 4, the dowel 4
By the engagement of a, the cassette guide 4 also returns to its original position. Therefore, the lever 6 connected to this guide 4 tilts to the left again using the support shaft 7 as a fulcrum. This allows the shutter 5 to return to its original state and completely shield the customer keyhole.

In addition, since the locking plate 3 is returned to its original state and each vertical hole 2a and hole 3a match, when the cassette 11 is taken out from the locking chamber IC, the upward movement of each magnet 12 due to the support of the spring 13 is caused. The bank lock can be automatically locked again.

Furthermore, the cassette 11 has a timer 19 inside it.
Therefore, at the time of initial application for use of the safe deposit box, the required time for use of the safe deposit box is set in the timer 19, and when the time has elapsed, the timer 19 is activated via the reset line 20. each AND circuit 16
．． Since a reset signal is issued to the contact point 17, the electrical circuit through which the power is supplied from the contact point 14 is automatically disconnected.

Therefore, after the circuit is disconnected, each electromagnet 15 becomes non-energized and the unlocking effect on the bank lock disappears, so that reuse or misuse can be reliably prevented. After use, the cassette 11 is returned to the person in charge of the safe deposit box in the reception department, and when applying for the use of another safe deposit box, the cassette 11 is returned to the person in charge of safe deposit boxes in the reception department.
By giving a specific code signal required to unlock the safe deposit box and setting an unlocking validity time limit, it is possible to unlock the bank locks of other safe deposit boxes again. The body can be used to unlock most bank locks.

In the above explanation, the unlocking method for safe deposit boxes was mainly described in detail, but the unlocking method according to the present invention is not limited to the scope of the above explanation, and can be similarly used for general locks. .

As explained above, since this invention is as described in the claims, there is no need for the bank's safety deposit box staff to be present when a single customer uses a total of 1 cars. .

Therefore, the cost of using the safe deposit box can be significantly reduced due to labor saving. In addition, the FR of this safe deposit box is
It only needs to be installed on the outside of the door plate, and there is no need for installation or wiring work using the internal space, so the space of the safe deposit box can be fully utilized, and there is no special wiring for the deposit box. There is no need to worry about electrical leakage accidents caused by wiring work, etc., and you can accomplish the mission of wiping a safe deposit box, which requires complete storage in its original condition. Since the unlocking effect disappears over time, the crime prevention effect of safe deposit boxes can be exploited.
