DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to tatami mats.

[0002]

2. Description of the Related Art A device in which charcoal is layered between straws has already been filed (Japanese Utility Model Laid-Open No. 6-6583). Also,
A charcoal storage section which is provided in the tatami with a charcoal storage section which can be ventilated with the outside air, which is divided into a substantially square shape by a partition plate, and in which charcoal is stored therein has been filed (Japanese Utility Model Registration No. 3002113).

[0003]

In the former method, amorphous carbon such as charcoal is sandwiched between tatami mats. However, charcoal powder oozes out in the upper and lower straw layers after long-term use, and eventually ends. Has the problem that charcoal powder comes out on the tatami mat.

[0004] In the latter tatami mat, the partition plate is provided vertically, so that when the tatami mat is stepped on, that portion feels hard, and after a long period of use, portions other than the partition plate sink, and the other portions sink. There is a problem of non-uniform deformation that comes up. In addition, there is a problem that the cost of the tatami mat is increased due to the complicated structure.

[0005] The present invention has been made to solve such problems, and an object of the present invention is to provide a clean tatami mat that does not have the above-mentioned problems, eliminates odors, and prevents the occurrence of pests and the like. To provide.

[0006]

A tatami mat according to the present invention, which has been made to solve the above-mentioned problems, includes a carbonized wood board layer and a layer such as a straw mat and a wood-based insulation board. It is characterized by the following.

[0007] The layers laminated above and below the carbonized wood board layer are:
It is a layer of straw mat, wood-based insulation board, polystyrene foam mat, etc. used in conventional tatami mats.

[0008] The carbonized wood board may be a single tatami mat board, a laminate of a plurality of thin boards,
Alternatively, a tatami mat 1 is formed by appropriately combining a plurality of small-area boards.
It may be one sheet. Furthermore, even if it does not completely enter the entire tatami mat, it is possible to obtain the effect of the present invention even if it occupies at least half or more of the area as long as it is almost even.

[0009]

Since the tatami mat according to the present invention has a charcoal layer inside, the odor and the like of the feet which are easily attached to the tatami mat are removed, and the generation and propagation of termites, mites and the like are prevented. In addition, when combined with a breathable layer such as a straw mat or a wood-based insulation board, it absorbs moisture from under the floor and does not wet the tatami surface. For this reason, the cleanliness and freshness of the tatami are maintained for a long time, and a refreshing living environment is provided.

[0010] The tatami mat according to the present invention is the same as the Japanese Utility Model Laid-Open No. 6-6583.
No charcoal powder is used as in the case of the charcoal-filled tatami described in Japanese Patent Laid-Open Publication No. HEI 7-202, so that the straw mat and the tatami mat do not become dirty. Furthermore, since a partition plate such as a tatami described in Japanese Utility Model Registration No. 3002113 is not used, a natural feeling of stepping can be obtained and non-uniform deformation does not occur.

When the tatami mat according to the present invention is used simultaneously with a straw mat or a wood-based insulation board, there is little problem with respect to the disposal of old tatami mats. That is, since the carbonized wood board can be incinerated, it is possible to incinerate the whole as it is without disassembling (breaking) the tatami mats. Also,
Since it is naturally decomposed by bacteria and the like, it can be directly discarded in fields and fields without incineration.

The carbonized wood board is preferably a carbonized cork board. As a result, in addition to the above functions and effects,
Due to the appropriate elasticity, there is an effect that a natural feeling similar to that of a tatami mat using a conventional straw floor or a polystyrene foam floor can be obtained.

1 is a sectional view of an end of a tatami mat according to an embodiment of the present invention. The tatami mat 10 of this embodiment is a carbonized cork board 1
The upper and lower sides of 4 are sandwiched between straw mats 12 and 15 to form a tatami floor, which is covered with a tatami mat 11. Carbonized cork board 1
4. The straw mats 12 and 15 are appropriately compressed after lamination, and hardened with a thread.

The carbonized cork board 14 is obtained by steaming a cork board and carbonizing it. It is desirable that steaming is not performed until complete carbonization, but incomplete carbonization to the extent that cork elasticity remains. Instead of the carbonized cork board 14, a thinned wood board hardened with pine tar, glue or the like may be used by steaming.

The reason why the carbonized cork board 14 is sandwiched between the straw mats 12 and 15 above and below as shown in FIG. 1 is to enable use even if the tatami floor is turned upside down, even if only one of the surfaces is used. For example, the straw mat may be placed only on the upper surface side.

As shown in FIG. 1, the carbonized cork board 1
By sandwiching a thin (about 1 mm) plywood 13 between 4 and the upper straw mat 12, the strength of the tatami mat is increased,
You can get a firm feeling of stepping, but this is not necessary. In addition, as in the case of a general tatami mat, the back of the tatami mat can be covered with a back sheet 16 such as a vinyl sheet, a knitted woven sheet, a goose, and an insect repellent sheet according to various purposes.
