Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to furniture that has excellent moisture-proofing effects and sound-proofing effects when used for partitions.

(b) Most conventional furniture faces the wall at a very close distance. Therefore, the air between the back of the furniture and the wall has poor circulation, and the humidity is high enough to cause condensation during the rainy season and summer, and it is easily affected by the outside temperature, so even when heating in winter, the humidity is high. is high.

Furthermore, with regard to the housing itself, the number of concrete buildings has increased recently, making it difficult to naturally ventilate the air between the walls and the furniture mentioned above, and there is no sign that the poor circulation will be improved.

On the other hand, if we consider a chest of drawers as a typical example of furniture, the back of the chest of drawers does not carry any load, it does not need to be beautiful because it is in contact with the wall, and the back of the chest of drawers is thick. For reasons such as a reduction in depth and an increase in weight, the front and both sides were generally made of thinner and softer wood than the front and both sides.

(C) Problems to be Solved by the Invention Therefore, in modern homes, humid air easily condenses, and the resulting moisture easily permeates through the soft wood on the back of the furniture and forms the inner surface of the furniture. It can also cause mold and corrosion, as well as the breeding of insects and microorganisms. Doing so could cause serious damage to clothing and other objects inside the furniture.

Furthermore, even if the material that makes up the back of the furniture does not allow water or moisture to penetrate at all, if it has low insulation properties, the heat inside the furniture will not flow out to the wall side through the material. (The inside of the furniture is cooled from the wall side), increasing the possibility of condensation forming as before.

However, the necessity of a ventilation system dedicated to the small space between the furniture and the wall was not advocated, and in the end, the only countermeasure was to move the furniture frequently.

Cdl Means for Solving the Problems In view of the above points, the inventor of the present invention, as a result of many years of intensive research, developed a foamed plastic material in order to solve this problem by using a member with airtightness and heat insulation properties in furniture. We have developed furniture that uses laminates as interior core materials. It is also thinner than any other material, and has the effect of not significantly reducing the depth of the furniture when used on the back of the furniture.

"Foamed plastics" include phenolic resin foam,
Thermosetting resin foams such as urea resin foam, epoxy resin foam, and polyurethane foam are suitable for use as part of furniture because they have excellent heat resistance and flame retardancy. However, other synthetic resin foams such as foamed polystyrene, foamed polyethylene, and polyolefin (polypropylene) foam may also be used as the material. The key is to provide airtightness to prevent air from outside the furniture from entering the interior of the furniture, and provide insulation to prevent the heat inside the furniture from escaping.

[Laminated body] is a structure made of the above-mentioned foamed plastic as an interior core material, and the simplest structure can be considered to be three layers. There are no limitations on the materials of the foamed plastic other than the interior core material. Therefore, for example, if the strength of the foamed plastic that is the interior core material allows, a coating applied to the surface of the foamed plastic may be used as one layer.

"Shell" refers to the part that forms the surface layer of the furniture body.
Consists of front, both sides, top, back, and bottom. Therefore, it does not include parts inside the furniture, such as partition plates, shelves, and clothing trays, and does not include parts that enter the interior of the furniture when closed, such as drawers.

``Furniture'' is ``tools used for everyday food, clothing, and shelter.

Chests, desks, chairs, etc. ” [Sonic Shoten: Kojien] and refers to all of these, but in particular, if a Japanese-Western chest of drawers, bookshelves, sideboards, desks, etc. that are installed at a very close distance to an indoor wall are constructed according to the present invention. The effect is great.

(e) Examples The present invention will be described in more detail below based on examples shown in the drawings.

FIG. 1 shows a laminate (11) used for furniture (11) according to the present invention.
2) shows an example of the structure.

As is clear from the figure, the laminate (2) has a three-layer structure, consisting of an outer layer (3), a heat insulating layer (4), and an inner layer (5). The outer layer (3) makes the laminate (2) a furniture (Z
), the surface will be in direct contact with the air in the gap between the wall and furniture (1). In this example, the outer layer (3)
The material used is processed laminated plywood. In addition, the insulation layer (
4) is made of styrene resin foam, and paulownia plywood with a beautiful surface is used for the inner surface R (5) that forms the inside of the furniture. The total thickness of the outer layer (3), the heat insulating layer (4), and the inner layer (5) was 20IllII+.

Next, FIG. 2 shows an example of furniture (1) (Western style mff1) using the laminate (2) shown in FIG.

In this example, the laminate was used for all of the "15 minute shells" that make up the surface of the furniture.However, the structural effect of the #1 layer (2), which is the greatest feature of the present invention, was The part to be replaced is the furniture back (B), and in that sense, the effect will not be significantly impaired even if the laminate (2) is used only on the back (B).Therefore, for example, if the furniture back (B) By using a laminate (2) and using natural boards for the sides and front side, the furniture will have the same external appearance as conventional furniture while still having various effects.

In addition, the foam used for the insulation layer (4) has excellent soundproofing effects, so when furniture (1) is used to partition a room, its soundproofing effect gives it a stronger sense of independence. be able to.

Note that unlike the inner layer (5), the outer layer (3) of the laminate (2) is not a surface that generally catches the eye, so it is not made into a clear layer like the example shown in Figure 1, but is made to be moisture resistant. It may also be a coating layer made of a paint with excellent properties. (Not shown) (") Effects of the Invention As explained in detail above, the furniture according to the present invention has a laminate with a foamed plastic interior core material, and has a small shell (").
It is characterized by having both airtightness and heat insulation properties, so moisture from the outside of the furniture does not seep into the interior of the furniture. Since the heat inside the furniture does not escape to the outside, it is less likely to damage the clothes inside, and even though it is a thin laminate, it has a large airtight insulation effect, so it does not reduce the effective volume of the furniture. It is an extremely useful material that has the following advantages: it is easy to reduce weight compared to other rooms, and when used as a room partition, it has an excellent soundproofing effect and provides good independence between divided spaces. It is something.
