Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a fireproof storage device, and more specifically, a container filled with a non-combustible liquid is housed in a storage space in a wall plate that constitutes an outer shell. When the container is installed and exposed to high heat in the event of a fire, etc., the container melts and the non-flammable liquid inside flows out into the container, and the vapor from the spilled non-flammable liquid fills the inside, causing the contents of the container to become Relating to a fireproof storage device designed to be protected.

(Prior art) Traditionally, fireproof storage devices (bookshelves, furniture,
Including safes, desks, cupboards, archives, and other storage equipment. )It has been known.

(Problem that the invention aims to solve) However, in this type of conventional fireproof storage equipment, the wallboard does not burn even when the temperature rises, and the heat is not easily transmitted to the interior, but it is When this happens, the internal temperature rises, causing problems such as the documents inside being damaged or burning.

This idea was made to solve the above problem, and the purpose is to provide a fireproof storage device that does not become hot inside even if exposed to high temperatures for a long period of time, and the documents inside will not be damaged or burned. With the goal.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the fireproof storage device according to the present invention is provided with an insulating non-combustible wall plate that forms the outer shell of the storage device whose interior is an article storage space. A storage space communicating with the article storage space is provided within the storage space,
A container made of a material that melts at a temperature above a certain level is housed in the housing space, and a nonflammable liquid is sealed in the container.

(Function) Therefore, if this fireproof storage device is exposed to high temperatures for a long time, such as during a fire, the temperature inside the storage space will rise, and if the temperature exceeds a certain level, the container will melt and the melting will occur. A non-flammable liquid flows out from the part where the non-flammable liquid flows out, and steam generated from the spilled non-flammable liquid fills the storage area, and the humidity caused by the vapor may damage or burn the documents stored inside. You will be protected from doing so.

(Example) What is shown in FIG.
5, 6, and 7 are connected to each other in a box shape to form an outer shell, and the inside thereof is a fireproof storage space 60. This is a fireproof storage device 1.

The front wall plates 4 and 5 of the fireproof storage device 1 are double-opened, and a shelf 9 and a drawer 10 are installed in an article storage space 60 therein.

The left, right, and front wall panels 2, 3, 4, and 5, which are particularly susceptible to heat in the event of a fire,
As shown in FIG. 1 partially cut away and as shown in FIG. The back plate 21 and the front plate 2
A container 30 filled with a non-combustible liquid 31 such as water is housed in a storage space 40 formed between the two.

Here, the top plate 22 is made of a heat-insulating, non-flammable material (a material with low thermal conductivity and difficult to burn even at high temperatures, e.g., 800°C or higher), but the spacer 23
The back plate 21 does not necessarily have to be made of a heat-insulating, non-combustible material. Further, the spacer 23 may be provided integrally with the front plate 22 or (and) the back plate 21. The size of the accommodation space 40 is also arbitrary.

Further, the container 30 is made of a meltable material such as synthetic resin or rubber that melts with heat, for example, at a temperature of 300°C to 350°C.
It is made of a material that melts and forms pores when it reaches a certain temperature. This container 30 may be a bag.

Also, places that are difficult to come into contact with heat in the event of a fire, etc.
For example, the upper, lower, and back wall panels 6, 7, 8 are 2
Although a conventionally used heat-insulating and non-combustible wall plate made up of two plates 51 and 52 in close contact with each other may be used, these wall plates 6, 7 and 8 are also used as the left, right and front wall plates. The same configuration as 2, 3, 4, and 5 described above may be used.

Further, by providing through holes 21a at appropriate locations in the back plate 21 constituting the wall plates 2, 3, 4, and 5, the storage space 40 and the article storage space 60 are communicated with each other.

Since the fireproof storage container of this embodiment is configured as described above, when documents and the like are stored in the article storage space 60 and the wall plates 4 and 5 are closed,
When the fireproof storage device 1 is exposed to high temperatures for a long time due to a fire, etc., and the internal temperature rises, the container 30 melts and a hole is formed in a part of it, and the nonflammable liquid 31 flows through the hole.
flows out and fills the accommodation space 40. The non-flammable liquid 31 filled in the storage space 40 evaporates due to heat, turns into steam, reaches the article storage space 60 through the through hole 21a, and the inside of the article storage space 60 is filled with steam. This steam protects the documents inside, preventing them from being damaged or burned by heat.

(Effect of the invention) Since the fireproof storage device according to the invention is constructed as described above, if it is exposed to high temperatures for a long time due to a fire or the like and the internal temperature rises above a specified level, the container will melt and some of it will melt. A hole is opened in the hole, and the non-flammable liquid flows out from the hole and evaporates, and the vapor reaches the article storage space through the hole, increasing the humidity in the storage space, and the documents inside. Even if it is exposed to high temperatures for a long time due to a fire, etc., the documents and other items stored inside will not be damaged or burned by the heat, making it significantly more fire-resistant than conventional fire-resistant containers. It becomes a fireproof container with improved properties.
