Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burglarproof structure for storages such as safes for offices, warehouses, homes, etc., storage archives, archive rooms and vaults.

[0002]

2. Description of the Related Art Storage boxes, such as safes and storage shelves, store items such as valuables and documents inside a box-shaped main body with an open front, and open and close a door or drawer that can open and close the opening of the main body. Stored items are protected from fire and theft by covering them with an opening and closing body such as a free drawer.

In an ordinary safe, a door is supported on one side of an enclosure wall of an opening portion of the main body so as to be openable and closable. The door is detachable from the enclosure wall and can be horizontally or vertically moved by a moving means such as a handle. There are provided a bar as a lock member which is moved in the direction, and a locking means such as a cylinder lock or a dial lock for restricting the operation of the moving means. From this configuration, the opening means of the main body is closed by the door to operate the moving means,
By operating the locking means after fixing the door to the main body by engaging the bar with the surrounding wall, the operation of the moving means is regulated and the door is completely locked to the main body. At this time, the bar is inserted into the surrounding wall by about 20 mm.

In a normal storage library, a drawer having substantially the same capacity as the space inside the main body is supported on the side wall of the main body so as to be able to be pulled out, and this drawer is also provided with a bar and a locking means similar to the door. ing. The drawer is completely locked with respect to the main body by operating the moving means, engaging the bar with the surrounding wall, and operating the locking means with the opening of the main body closed with the front wall. You.

[0005] Such storages include the following. Fireproof safes A fireproof safe that protects stored items from fire is generally known to prevent heat transfer to the inside of the body by enclosing a fireproof material such as a mixture of cement and water inside the body or door. There is known a technique for improving fire resistance by mixing a mixture of cement and water with pearlite or a foaming agent to generate bubbles. In this fire-resistant safe, the outer frame of the door and the edge of the enclosing wall of the main body open surface in which the outer frame is fitted have a lightning-shaped or step-shaped cross-sectional shape, and the total area of the facing portion between the outer frame of the door and the edge is reduced. A smoke bending (smoke return) structure is adopted which protects the stored items by increasing the distance of the flame, heat, smoke and the like from the outside to the inside by increasing the size.

As a theft safe for protecting stored items from theft, a hammer using a fireproof material provided with a wire netting, a steel piece, a high-hardness protective plate, or a thick iron plate covering the fireproof material is used. It is designed to withstand vandalism, such as blows by a torch, cutting by a torch, cutting by a cutter, and prying with a crowbar. Further, the locking means includes a re-locking structure having a second locking mechanism for automatically fixing the bar when the locking mechanism is broken by an external force (for example, Japanese Utility Model Application Laid-Open No. 59-2616).
No. 4 gazette).

[0007] Powerful safes, super-strong safes, and storage archives A strong safe and a super-strong safe having both fire resistance and anti-theft performance are provided with the above-mentioned smoke bending structure and a thick iron plate covering a fire-resistant material, or a fire-resistant safe. There is a so-called secondary storage in which an anti-theft safe is placed inside a safe. As storage archives, there are those that have fireproof performance like fireproof safes and those that do not have fireproof performance.

[0008]

In the above-mentioned fire safe,
By embedding a wire mesh, a billet, a protection plate, or the like in a refractory material, or by changing the material or the number thereof, the resistance to destruction, fusing, cutting, or prying can be changed in the same manner as in the anti-theft safe. Among them, in order to increase the resistance against prying-up, which is the most difficult measure, it is conceivable to provide a plurality of bars and to use a plurality of high-hardness protective plates which are not easily deformed.

However, most of the safes used in offices and homes are usually fire-resistant safes, and even if measures are taken to provide a plurality of bars, the bars are at most 20 m from the main body.
m, the engagement between the main body and the bar can be easily released by significantly deforming the side wall of the main body where the bar is fitted using a long bar. Is released in a short time. In addition, the countermeasure using a plurality of high-hardness protective plates has a problem that the cost is increased and the weight is significantly increased.

In a strong safe or an ultra-strong safe, the iron plate has a sufficiently large thickness to provide sufficient resistance to prying. However, the thick iron plate increases the weight of the safe and increases the normal fire resistance. There is a problem that the price is greatly increased as compared with the safe. In particular, the weight increases (about 50 kg or less for a small safe, about 200 to 300 kg for a fireproof safe, but about 800 to 1000 kg for a strong or super-strong safe), and the strength at the wall or on the beam is high. Because the installation place of the safe is limited to a high place (the floor strength of the building according to the Building Standards Law is 180 kg / m ² in a house, a sick room, and 23 in a classroom).
0 kg / m ^2, office, the department store is 300 kg / m ²⁾ with a problem on the layout, if installed in other locations should not without providing a reinforcing member, and correspondingly cost I will.

The present invention solves the above-mentioned problems, and provides a storage box such as a fire-resistant safe, a storage archive, etc., which can improve the anti-theft property without increasing the cost and weight, and further improves the anti-theft performance. Anti-theft safe, which can be improved
The purpose is to provide storages for strong safes and super strong safes.
