Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a key storage box for storing keys of rooms, etc.

[Prior Art] This type of key storage box is placed in large numbers at the front desk of a hotel, for example, or in the manager's room of an apartment building, a tenant, a factory, etc., and is used to store registered magnetic cards. By reading the code and entering the PIN number, the controller sends an electrical signal to unlock the electric lock and open the door.

Then, the user takes out the key to the room, etc., or enters the room.

The key storage box is comprised of a box body with an open front and a door pivotally attached to the opening surface of the box body so as to be openable and closable.

Then, by inserting the pre-registered magnetic card into the card reader inside the controller, reading the data, and entering the PIN number using the numeric keypad, the electric lock installed in the key storage box will be activated and the lock will be unlocked. The door can be opened by locking it. While the unlock signal is being sent to the key storage box from this operating device, the door of the key storage box can be opened manually and the key stored inside can be taken out.

[Problem to be Solved by the Invention] FIG. 8 shows a conventional example, in which a door 3 is pivotally attached to an opening 2 of a box body 1 so as to be openable and closable, and the end of the door 3 is attached to the edge of the box body 1. When the door 3 is unlocked by a signal as described above, the door 3
The door 3 is opened by inserting the tip of a finger into the gap 5 between the end of the box body 1 and the edge of the box body 1 on the side of the stepped part 4.

However, as shown in FIG. 9, when the key storage box is locked, the ll! between the door 3 and the box body 1! Interval 5
By inserting the tip of the driver 6 into the box body 1 and using the edge of the box body 1 as a fulcrum to pry open the door 3 with the driver 6, the door 3 can be opened.

The present invention has been provided in view of the above-mentioned points, and an object of the present invention is to provide a key storage box that is difficult to open even if the user tries to forcefully open the door.

[Means for Solving the Problem] The present invention makes the front side of the end of the door thinner as the end approaches, and the front side of the edge of the opening of the box body opposite to the end is made thinner. It is made thinner in some parts.

[Function] Therefore, the front side of the edge of the door and the front side of the edge of the opening of the box body facing the edge are each formed thin, so that even if you try to pry it open with a screwdriver, etc., it will not work as a lever. I was trying to force the door open.

[fruit! EMBODIMENT OF THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. Second

and door 3. As shown in FIG. 1, the edge of the door 3 is formed with a curved surface 7 that is recessed in an arc shape on the front side, and the edge of the box body 1 is also recessed in an arc shape on the front side. A curved surface portion 8 is formed. Therefore, the end portion of the door 3 is formed thinly by the curved surface portion 7, and the edge portion of the door 3 is formed thinly by the curved surface portion 8.
#1 of box body 1 facing . The lower part is made thinner. Although there is a wide gap between the edges on the front side of this curved surface portion 7.8, even if the tip of a screwdriver or the like is inserted into the curved surface portion 7.8, it is difficult to get caught on the edge of the door 3.
The edge of the opening 2 of the box body 1 is formed thin, so even if you try to pry it open with leverage, it will not be possible to open it.
Although the edges of the edges are curved, they may be tapered and thin.

3 and 4 show a card holder 9 which also serves as a hinge attached to the back side of the box 3, with a hinge part 10 formed at one end of the card holder 9, and a hinge part 10 formed at the other end on the side of the box body 1. A lock rod 11 for locking with the formed electric lock is provided with insertion holes 12 at the top and bottom of the hinge section 10, respectively, and is located in a recess 13 at the center of the hinge section 10. Holes 15 are bored at the top and bottom of the shaft portion 14 . The bottle 16 is press-fitted into the hole 15 of the shaft portion 14 through the insertion hole 12 of the hinge portion 10 of the card holder 9, and the shaft portion 14 is inserted into the front plate 1 of the box body 1.
By attaching it to the back of box a, the door 3 can be attached to the box body 1 so as to be openable and closable.

A hole 17 is bored at the other end of the card holder 9,
The lock rod 11 is press-fitted into this hole 17, and the lock rod 11 is fixed to the card holder q. Further, a recess 18 is formed on the back side of the card holder 9, and this recess 18 serves as a storage section in which a magnetic card 19 is stored. In this manner, in this embodiment, since the hinge portion 10 and the lock rod 11 are integrated into the card holder 9, the hinge adjustment and engagement adjustment with the electric lock side can be simplified.

Figure 5 shows a system configuration diagram using the above key storage box,
This system consists of a key storage box A for storing keys, and a key storage box A for storing keys.
and a printer device C that prints out the status of keys in and out of the key storage box A (time, box number, etc.). As described above, the operating device B sends an unlocking signal to the key storage box A to drive the electric lock and open the door 3. In addition, the key storage box A sends a signal to the controller B indicating that the door 3 is open, a signal indicating whether there is a key inside, and a signal indicating whether the door 3 is closed and the electric lock is locked. Send. Further, the door 3 is automatically opened when an external signal obtained in an emergency such as a fire, an intruder, or an equipment malfunction is received. Furthermore, when the emergency situation has passed, the door 3 is automatically locked. Therefore, warning/cancellation signals are exchanged between the operating device B and the key storage box A.

By the way, when importing input/output signals to the CPU in controller B, if the number of input/output points is small, 110 ports are provided individually for importing, but as the number of input/output points increases, the number of 110 ports increases. Matrix wiring is often used to reduce the number of boats and power distribution. FIG. 6 shows an example of such a matrix wiring.
The alarm/cancellation signal is being captured. However, although the above purpose can be achieved with matrix wiring within controller B,
Wiring within a panel incorporating the operating device B and a large number of key storage boxes A tends to become complicated.

Therefore, in this embodiment, it is set as shown in FIG. That is, when 10 key storage boxes A are arranged in the panel in this embodiment, one printed circuit board 22 is placed on the side for each key storage box A in one vertical row, and the operating device A printed circuit board 21 is provided to be connected to the CPU board 20 of B. Further, each key storage box A is connected to a printed circuit board 22 through a connector 23, and the printed circuit boards 21 and 22 are connected through a connector 24. Here, as mentioned above, the key storage box A outputs a door signal, a warning/release signal,
Additionally, an unlock signal is input. The printed circuit board 21 connected to the CPU board 20 handles conversion signals to the 11010 CPU printed circuit boards 22, and also handles the conversion signals to the printed circuit boards 22.
2 handles signals from each key storage box A and conversion signals to the printed circuit board 21. Therefore, by configuring the system in this way, if the number of key storage boxes A increases, the number of printed circuit boards 22 can be increased and the number of printed circuit boards 22 can be connected to the printed circuit boards 21 using connectors. Therefore, the wiring within the panel can be standardized, that is, it can be made into a unit, and additional key storage boxes A can be easily added.

[Effects of the Invention] As described above, the present invention makes the front surface of the end of the door thinner toward the end, and the front surface of the edge of the opening of the box body opposite to the end is made thinner. Since the front side of the edge of the door and the front side of the edge of the opening of the box body facing the edge are formed thinner, I tried to separate them with a screwdriver etc. The door also acts as a lever to prevent the door from being forced open.
