Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a large safe for business which is constructed integrally with a building and other buildings requiring strong and heavy thick doors (doors with a thickness of 60 cm or more) ( For example, the present invention relates to a novel hinged device for thick doors, which is installed in storages, warehouses, etc. and facilities.

Conventional technology and problems It is known that a hinge is provided across the back side of the door body and the wall body, but since such a back hinge device is configured for a thin door, it is a strong and heavy door. Cannot be used (for example, issued by Takigen Manufacturing Co., Ltd., 1986
Revision No.13, 4th Edition, September 2013, TAKIGEN No.13-3, 2
See pages 28-247).

Since there is no back hinge device for thick doors or a hidden hinge device for thick doors (a hinge device arranged so that it cannot be seen from the front), the large safe, other buildings and facilities equipped with thick doors, etc. , The hinge device is exposed, but there are often theft cases in which the exposed hinge device is destroyed or burned to steal stored items.

The present invention has been made paying attention to such circumstances, and an object thereof is to provide a back hinge device or a similar hidden hinge device suitable for crime prevention, as well as capable of easily opening and closing a strong and heavy thick door. To do.

Means for Solving Problems A means for achieving the above-mentioned object is a thick door in which a wall hinge is arranged at the opening side portion on the back side of the wall body and is arranged at the opening portion of the wall body. That is, the door hinge is arranged on the wall hinge side portion on the back side of the wall hinge, and the wall hinge and the door hinge are connected to the intermediate hinge.

Work If you pull the thick door forward and remove it from the opening and make the wall parallel, the intermediate hinge will be pulled along with the thick door and will move, so after moving the intermediate hinge, move the thick door to the wall hinge. If it is turned to the installation side, it can be opened largely around the intermediate hinge.
The opened thick door is pivoted about the intermediate hinge to a position parallel to the wall body and returned, and then pushed to be fitted into the opening and closed. Then, the hinge device constituent members such as the wall hinge, the door hinge, the intermediate hinge, and the rotating plate cannot be seen from the front when the thick door is closed.

Examples The drawings show an example in which a thick door is provided in a crime prevention tool for a cash dispenser (hereinafter, this crime prevention tool is referred to as a protector), and a hinge device is configured for the thick door.

The protector P is arranged on the front side and the back side of the cash storage portion of the cash dispenser CD, but depending on the arrangement of the cash dispenser CD, it is arranged only on the front side. The protector P has a strong structure so that the wall body 1 is not easily destroyed or burned out, and has a thick door 3 openable and closable on the front wall body 1 for cash withdrawal and the like. The thick door 3 is locked by a locking device (not shown) that is not visible from the front except when the time is up.

Wall 1 to be placed on the front side of the cash dispenser P
Is an opening 1'having an appropriate shape such as a square or a square on the front wall.
And the wall hinge 2 at the opening side part on the back side.
Is provided.

The wall hinge 2 is constructed like a well-known hinge, one side edge side of the rotating plate 2'is fixed to the back side of the wall body 1, and the other side edge side of the rotating plate 2'is a rotating plate of the intermediate hinge 5. It is fixed to 5'and is connected to the intermediate hinge 5. In the wall hinge 2, one side edge side of the rotating plate 2'is fixed to the back side of the wall body 1, so that even if the thick door 3 is opened, the rotating plate 2'will not move at a predetermined position. Rotate.

The thick door 3 is firmly configured so as not to be easily broken or burnt out together with the wall body 1, and is provided in the opening 1 ′ of the wall body 1 so as to be openable and closable. The thick door 3 is provided with a door hinge 4 on the back side on the wall hinge 2 side portion of the wall body 1, and a caster on the lower side, and other rolling aids, sliding aids, etc. for smoothing the opening and closing of the thick door 3. The auxiliary tool 6 is attached.

The door hinge 4 is constructed like a well-known hinge together with the wall hinge 2 and the intermediate hinge 5, one side edge side of the rotating plate 4'is fixed to the back side of the thick door 3 and the other side of the rotating plate 4 '. Edge side is intermediate hinge 5
It is fixed to the rotating plate 5'and is connected to the intermediate hinge 5. The door hinge 4 is arranged in parallel with the wall hinge 2 at a position facing the wall hinge 2 on the back side of the thick door 3.

The intermediate hinge 5 has a rotary plate 2 ′ of the wall hinge 2 and a rotary plate 4 ′ of the door hinge 4 fixed to both side edges of the rotary plate 5 ′ at an intermediate portion between the wall hinge 2 and the door hinge 4, respectively. , The wall hinge 2 and the door hinge 4 are connected. The intermediate hinge 5 is provided in parallel with both the wall hinge 2 and the door hinge 4 at the intermediate position between the wall hinge 2 and the door hinge 4 in order to make the thick door 3 openable and closable. To do.

A plurality of hinge devices configured as described above are arranged in the height direction on the back side of the wall body 1 and the thick door 3.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, the hinge device cannot be seen from the front at all. Therefore, it is troublesome to discover the hinge device, and the hinge device can be destroyed only after destroying the wall body, the thick door, etc., and it takes time to destroy the hinge device until it is completely destroyed. It can be expected that a destroyer will be found in the area, and it can be a hinge device suitable for crime prevention.

To open and close the thick door, once pull the thick door toward you to remove it from the opening and make it parallel to the wall body, the intermediate hinge will be pulled together with the thick door and will move. If the thick door is rotated toward the wall hinge installation side after the transition, it can be opened largely around the intermediate hinge. The opened thick door pivots back to the position parallel to the wall with the middle hinge as the center,
If you press it after that, it will fit into the opening and be closed. Therefore, even a strong and heavy thick door can be easily opened by the two operations of pulling and rotating and can be easily opened and closed by the two operations of rotating and pushing.
