Description

[Detailed description of the invention] This invention relates to a door closure confirmation device for a safe deposit box, and is designed to prevent the lock provided on the door from being locked especially when the inner box is not stored.

The general structure of safe deposit box equipment in banks, etc. will be explained based on FIG.
2... into a large number of safe rooms 3, 3..., each safe room 3 is separately attached with a door 5 having a lock 4, and an inner box 6 is housed therein. The lock 4 has two keyholes 7a and 7b, and has a so-called double key structure. In other words,
The customer keeps the key (rental key) that matches one keyhole 7a, and the bank keeps the key (card key) that matches the other keyhole 7b, making it impossible to open the door with either key alone. The structure is as follows.

Therefore, when actually opening the door, the customer must go to the safe with a bank witness and unlock the card key before the rental key can be inserted and the safe door 5 opens. It is becoming more and more common. On the other hand, when closing the door, the safe door 5 itself is pushed to a predetermined position without a key, and the safe door 5 is automatically locked.

By the way, as mentioned above, once the door is opened in the presence of a bank witness, the customer himself/herself pulls out the inner box and performs the necessary insertion/removal operations, but at that time, the inner box remains removed. It can often happen that the safe door closes. In that case, the door must be opened again in the presence of the bank's witness, which is extremely troublesome for both the customer and the bank, and is not necessarily satisfactory in terms of labor saving. It wasn't.

Therefore, this idea was made against the above background, and the safe door could not be locked unless the inner box was properly stored, thereby eliminating the above-mentioned monetary damage. It is something to do.

That is, in this invention, one end of the rod that is linked to the operation of putting in and taking out the inner box faces the locking hole into which the locking bar of the lock fits, and when the inner box is stowed as specified, one end of the rod faces the locking hole into which the locking bar fits into the locking hole. It is designed so that it can be locked only when it is moved back to a position where it does not interfere with the vehicle.

An embodiment of this invention will be described below with reference to FIG. 2 and the following drawings. However, since the configuration of each vault is the same as described above, only one vault will be explained.

In Figures 2 to 4, 3 is a vault whose top and bottom sides are partitioned by partition plates 2, 2..., and 5 is a vault door attached via a hinge 8 at the front opening of the vault 3. The safe door 5 has a double key lock 4 attached to its inner surface, and its locking bar 4a is biased in the forward direction by a spring (not shown).

Further, a locking hole 9 into which the locking bar 4a fits is formed in the partition plate 2a constituting the safe 3, and an operating rod 10 is horizontally disposed outside the locking hole 9. This operating rod 10 is inserted into and supported by guide holes formed in support plates 11, 11, and is configured to be movable back and forth.Furthermore, its rear end is bent into an L-shape and is formed at the rear end of the partition plate 2a. It protrudes into the safe chamber 3 from the guide groove 12 . Note that the bent portion 10a and the guide groove 1
2, rotation of the operating rod 10 is prevented.

On the other hand, a rectangular plate 13 is attached to the tip of the operating rod 10.
One end of the lock hole 9 is exposed to the lock hole 9. A coil spring 14 is interposed between the plate 13 and the support plate 11, and this urges the entire operating rod 10 in the forward direction.

In the above-described configuration, when the inner box 6 is properly stored as shown in FIG. As a result, the locking bar 4a fits into the locking hole 9 to maintain the locked state. Note that the spring force of the coil spring 14 is set to be relatively weak enough to move the operating rod 10 forward in a no-load state, so that the spring force of the coil spring 14 is set to be relatively weak enough to move the operating rod 10 forward in a no-load state. In this case, the operating rod 10 will not be moved forward.

Meanwhile, as mentioned above, use the rental key and card key to unlock the lock 4 and open the door, and open the inner box 6.
When the locking bar 4a is pulled out, the operating rod 10 moves forward, and the plate 13 at the tip comes into contact with the fitting part of the locking bar 4a, that is, the front end surface of the locking hole 9, closing the locking hole 9, thereby causing the locking bar 4a to slide into the locking hole 9. (Fig. 4).

Therefore, even if you try to close the metal door 5 without putting the inner box 6 into the vault 3, the plate 1
3 becomes an obstacle and the locking bar 4a cannot be fitted into the locking hole 9 and the lock is not locked, and as a result, the customer is made aware that the inner box 6 is not stored.

When the inner box 6 is properly stored, the inner box 6
Following this movement, the operating rod 10 retreats, and the plate 13 retreats to a position where it does not interfere with the fitting of the locking bar 4a, that is, to the innermost surface of the locking hole 9 (FIG. 4). Therefore, when the safe door 5 is pushed to the specified position in this state, the locking bar 4a and the locking hole 9 are fitted together for the first time, and the safe is automatically locked. Therefore, from now on, the door will not be opened unless the rental key and card key are used together as described above.

As is not clear from the above explanation, in the safety deposit box door closure confirmation device of this invention, a locking bar is fitted to one end of the operating rod that moves back and forth in conjunction with the movement of taking in and taking out the inner box. It faces into the locking hole and is configured so that it can be locked only when the inner box is stored as specified and one end of the rod is retreated to a position where it does not interfere with the fitting of the locking bar into the locking hole. Therefore, even if the door is closed by mistake without storing the inner box, it will not be locked. Therefore, the user can be made aware that the inner box has not been stowed yet, so it will not be locked if the door is accidentally closed. It is extremely convenient because it can prevent inconvenience and there is no need to require a bank staff member to be present when the door is reopened, unlike in the past.
Furthermore, on the bank side, it can greatly contribute to labor saving as it saves the trouble of reopening a door that has been accidentally closed, and is particularly effective in cases where there are many users of the safe deposit box at the same time.
