Abstract

PROBLEM TO BE SOLVED: To improve the function of a tatami mat by sticking a matting on the surface of a base material consisting of a corrugated board or a honeycomb board, and sewing edge material on both side edges. SOLUTION: As occasion demands, straw layers 7 in a bundled state are sewn by a thread on the upper and lower faces of a base material piling corrugated board 1 into a plurality of layers for increasing strength so as to be fixedly secured. Next, a matting 8 as a surface material is stuck onto the surface of the straw layer 7 on the upper face side, a vinyl sheet 9 is stuck onto the surface of the straw layer 7 on the lower face side, and edge material is sewn on both side edges. Instead of this, a honeycomb board can be used for the base material, or the honeycomb board and the corrugated board 1 can be used together by arranging the corrugated boards 1 on the upper and the lower faces of the honeycomb board. Hereby, because the weight is reduced, the handling is facilitated, the manhour can be reduced because of simple manufacture, the heat insulation can be improved, and further humidity of the room can be adjusted because it has a function of absorbing and discharging moisture.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a tatami mat laid in a Japanese-style room.

[0002]

2. Description of the Related Art A tatami mat is a floor material unique to Japan, and the tatami mat is laid in a Japanese-style room. Conventional tatami mats are made by bundling straws of a certain length into a rectangular plate, gluing them on the surface, and sewing fabric edges on both sides. The tatami mats made with such straws as the main material are suitable for the climate of Japan, absorb indoor moisture during the humid season during the rainy season, and release moisture during the summer dry to cool the room. There is also an effect.

However, today there is a shortage of straw as a raw material, and on the other hand, there are few tatami craftsmen, and it is becoming difficult to manufacture traditional tatami mats. In other words, straw was produced by farmers as a by-product of rice cultivation. Crushed and left in the field.

[0004] On the other hand, the conventional tatami manufactured by bundling such straws is very heavy. In particular, tatami that absorbs moisture cannot be carried alone and placed in a room. In recent years, Happo resin plates have been used in place of these straws,
In many cases, tatami is manufactured by wrapping the Happo resin plate.

FIG. 4 shows a general appearance of a tatami mat, and FIG. 5 shows a cross section of a tatami mat using a recently used Happo resin plate. As shown in the figure, Happo resin plate (a)
Straw layers (b) and (b) are provided above and below, a vinyl sheet (c) is attached to the lower surface, and a goza (d) serving as a surface material is attached to the upper surface. Of course, both sides of the tatami
(E) and (e) are stitched together. Thus, recent tatami mats composed of Happo resin plate (a) as a base material are light in weight and convenient to handle, but Happo resin plate (a)
Does not have the ability to absorb moisture, and cannot achieve the humidity control effect of the room provided by conventional tatami mats.

[0006]

As described above, the conventional tatami mat has the above-mentioned problems. The problem to be solved by the present invention is these problems, light and easy to handle,
Moreover, it provides a tatami mat with room humidity control function.

[0007]

The tatami mat according to the present invention is light and easy to handle, and has a humidity control function by absorbing moisture in the room and releasing moisture. Use a cardboard or honeycomb plate instead. Sometimes a cardboard version and a honeycomb version are used together. Corrugated cardboard and honeycomb plates are of paper quality, but have high strength and are very light and are not inferior to Happo resin plates.

[0008] Here, the corrugated cardboard plate and the honeycomb plate need to have a thickness as a tatami mat base material, and thus may be composed of a plurality of layers. In addition, a suitable paper is used in consideration of the strength, and the material of the corrugated board plate and the honeycomb plate is not particularly limited. It is a tatami mat based on a corrugated board or honeycomb plate, and it is free to configure tatami by combining other suitable materials, but goza as a surface material is stuck on the table,
Edges are sewn on both sides. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0009]

FIG. 1 is a sectional view showing a tatami mat according to the present invention. The cardboard board 1 has basically the same structure as a conventional cardboard board, but is constituted by a plurality of layers in order to increase its strength. FIG. 2 shows a corrugated board 1 having three layers 2a, 2b and 2c.
The upper plate 3 and the lower plate 4 are provided with two middle plates 5 and 5 at a fixed interval between the upper plate 3 and the lower plate 4. Are connected to the space formed by the upper surface plate 3, the middle plates 5, 5, and the lower surface plate 4 through the corrugated paper 6, 6,. Cardboard version. To increase the strength of the corrugated board 1, the number of layers can be increased. However, the thickness of the upper plate 3, the lower plate 4, and the middle plate 5 may be increased, and the paper quality may be enhanced.

On the other hand, the folding substrate of the present invention is not limited to the corrugated cardboard plate 1 but may be a honeycomb plate. This honeycomb plate is a light and high-strength plate-like body as is often used as a panel core material for partitioning, and is a base material that can satisfy the object of the tatami mat according to the present invention. The honeycomb plate has a honeycomb material in which a number of small spaces are formed between an upper surface plate and a lower surface plate. Also in the case of the honeycomb plate, the space is made smaller, and the thickness and the material of the upper surface plate and the lower surface plate are strengthened, so that the honeycomb plate has high strength and is durable.

As shown in FIG. 1, the tatami mat of the present invention is provided with a straw layer 7 on the upper surface of the corrugated cardboard plate 1 and a straw layer 7 on the lower surface as well. The straw layer 7 forms a layer in a bundled state, and is fixed to the upper and lower surfaces of the corrugated cardboard plate 1. The fixing means is not particularly limited, but is generally sewn via a strong thread. A goza 8 as a surface material is bonded to the upper surface of the straw layer 7, a vinyl sheet 9 is bonded to the lower straw layer 7, and edges are provided on both sides and sewn.

FIG. 3 shows another embodiment of the present invention, and shows a cross section of a tatami mat in which a honeycomb plate 10 and a cardboard plate 1 are used in combination. Corrugated cardboard plates 1 and 1 are provided above and below the honeycomb plate 10, and a plywood 11 is interposed between the honeycomb plate 10 and the cardboard plate 1 on the upper surface side. A goza 8 as a surface material is attached to the upper cardboard plate, and a vinyl sheet 9 is provided on the lower surface of the lower cardboard plate.
Furthermore, edges 12, 12 are attached to both sides. Therefore, no straw layer is used. As described above, the tatami mat of the present invention uses a corrugated cardboard plate or a honeycomb plate as a base material, and generally has a straw layer on the upper and lower surfaces and a goza on the surface, and has the following structure. The following effects can be obtained.

[0013]

The tatami mat of the present invention uses a corrugated cardboard plate or a honeycomb plate as a base material, so that it is light and easy to handle. It does not take. In addition, the corrugated board and honeycomb plates are made of paper and form a large number of small spaces, so they have excellent heat insulation properties, and also have the function of absorbing moisture and releasing the absorbed moisture. It is the same as a tatami mat based on straw from, and has a room humidity control function.
