DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami apparatus for forming a tatami room in a building such as a general house or an apartment house.

[0002]

2. Description of the Related Art In a dwelling room, a room with tatami mats is cool in summer and warm in winter due to the characteristics of the tatami even in a high-temperature and high-humidity environment. It is an indispensable space to provide. Tatami,
It is composed of a tatami mat woven with rush, a tatami floor on which the tatami mat is sewn on the surface layer, and auxiliary materials such as tatami mats. Tatami mats are generally made of well-dried rice straw as a material and sewn into a plurality of layers, and a large amount of air is sucked into the inside to form an air layer. The tatami mat has appropriate hardness and softness due to the feel, color, and luster of the grass, which is the material of the tatami mat, and the structure of the tatami floor that has inhaled a large amount of air. Tatami mats have excellent functions required for flooring, such as safety when falling, walking, heat insulation, or heat insulation.

That is, the tatami mats have sufficient cushioning properties to reduce a fall accident in a room, provide an appropriate warming / cooling sensation or a tactile sensation without causing fatigue, and have an effect of producing a slipping sensation. In addition, the tatami mat has the effect of supporting the lying body with appropriate hardness and reducing the load on the body with appropriate softness to relax the body. In addition, the tatami mat enables daily barefoot life, strengthens the legs and improves health,
It has the effect of suppressing low back pain and knee pain.

On the other hand, the tatami mat is replaced with a traditional tatami mat made of natural material consisting of a tatami mat of natural grass and a tatami floor made of rice straw, and a polystyrene foam having a higher heat insulating effect as a material of the tatami mat. There are also provided so-called synthetic tatami mats made of new materials such as rugs and insulation boards. In a synthetic tatami, a tatami floor is composed of these new materials alone, or a tatami floor is formed by sandwiching a new material between rice straws. Synthetic tatami mats are lightweight and have excellent heat insulation and moisture resistance, and their thickness can be freely changed.

As a synthetic tatami, for example, Japanese Patent Laid-Open No.
As described in U.S. Pat. No. 326,273 "tatami", there is also provided one using a carbonized cork board as a material of a tatami floor. Such a synthetic tatami is characterized in that air permeability is maintained by the action of the carbonized cork board, and insect repellent or deodorizing action is exhibited. Further, such a synthetic tatami has a feature that it can be incinerated and can be disposed of without being incinerated.

[0006]

As described above, tatami mats are extremely ideal flooring materials in the high-temperature and high-humidity environment in Japan. Due to the problem of pests and the like, it has become less used. That is, a house is recently provided with a closed structure for reasons such as a demand for cooling and heating efficiency and a demand for more privacy due to changes in lifestyle. House ticks have poor indoor ventilation,
The damage occurs in a room where cleaning is not performed well, and the damage has become a very important problem particularly in a high-tight airtight middle-to-high-rise house equipped with air conditioning and heating equipment.

[0007] Measures against pests such as house ticks have a sufficient effect by ensuring air permeability in the room and encouraging cleaning and drying the tatami mats. However, there is a problem with tatami drying, as well as securing and transporting heavy tatami mats and labor, and particularly in urban mid- to high-rise apartments, it is difficult to secure a place, and thus there is a problem that it cannot be implemented at all.

[0008] Under such circumstances, tatami mats which have been treated for pests and insects by applying a chemical treatment have recently been provided. However, such tatami mats have the problem that the drug contaminates the indoor air causing allergies or worsening. Further, such a tatami mat has a problem that the effect of the chemical treatment deteriorates with time due to long-term use.

Further, the synthetic tatami using a new material generates toxic gas in the event of a fire or the like and has a problem in disposal. Furthermore, a synthetic tatami using such a new material has not yet achieved the feel and texture of a familiar tatami mat, and gives a resident a sense of discomfort as well as being unsatisfactory. Similarly, a synthetic tatami using a carbonized cork board has a problem that it does not provide the resident with the feel and texture of the main tatami mat and is extremely expensive. Regarding tatami mats, there is a much higher demand for main tatami mats made of natural materials than the synthetic tatami mats described above.

Therefore, the present invention has been proposed for the purpose of providing a tatami apparatus which follows the significance of the tatami mat made of a natural material, is easy to handle, and suppresses the occurrence of pests such as house mites. Things.

[0011]

A tatami apparatus according to the present invention which achieves the above-mentioned object has a structure in which a carbonized cork member is laid on a floor substrate of a building to form a carbonized cork base layer, and the cork carbonized base layer is formed on the cork carbonized base layer. The main tatami mat is constructed by laying a tatami mat and a rice straw as raw materials and a tatami floor sewn in a plurality of layers. Further, the carbonized cork member is subjected to dustproofing.

[0012] According to the tatami mat apparatus of the present invention configured as described above, the occupants can fully enjoy the texture of the tatami mat and the cork carbonized base layer constituted by the carbonized cork member can sufficiently provide the occupants. Air permeability and elasticity are secured. Due to the characteristics of the cork material, the tatami apparatus secures functional requirements for excellent sound insulation and sound absorption, heat insulation, water and chemical resistance, and insect and mold resistance, and suppresses the occurrence of pests such as house mites. The tatami device simplifies the laying operation and the tatami drying process by reducing the weight.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIGS. 1 and 2, a tatami apparatus 1 according to an embodiment of the present invention includes a main tatami 2 and a carbonized cork panel 3 and is laid on a concrete slab 4 of an apartment house, for example. The tatami mat 2 is composed of a tatami mat 5 woven from rush grass and a tatami mat floor 6 on which the tatami mat 5 is sewn on the surface. Of course, in the main tatami mat 2, a tatami edge is sewn to the periphery of the tatami table 5, though not shown.

The tatami mat 2 uses a tatami table 5 which is generally used. The main tatami mat 2 has a carbonized cork panel 3 described in detail below.
Since the base layer is formed by the method, the thinnest one is selected from the tatami floors 6 which are usually manufactured with a thickness of about 30 mm to 60 mm, and the weight and cost can be reduced. As shown in FIG. 2, the tatami floor 6 is made of rice straws sewn vertically and horizontally in multiple layers between a surface arrangement 7 and a bottom floor 8. In the tatami apparatus 1, the main tatami 2 is replaced or turned inside out in the same manner as in the related art, but the use of the lightweight tatami facilitates carrying out and laying. Of course, the tatami mat 2 is not limited to the lightweight tatami mat described above.

The carbonized cork panel 3 is formed from a cork material, has a thickness of about 15 mm to 20 mm, and has a density of 160 kg / m ^{3 to} 180 kg / m ^3.
A panel-shaped carbonized cork material having a predetermined outer shape is used. Of course, the carbonized cork panel 3 is not limited to such specifications. In the present invention, not only a panel-shaped carbonized cork but also a tile-shaped or sheet-shaped carbonized cork may be used.

By the way, as is well known, cork material is formed by a plant material consisting of dead microcells obtained from a cork tissue formed in a cork-forming layer, which is a protective outer shell of cork oak. For cork, suberin is 45
%, Lignin 27%, cellulose and polysaccharide 12%,
The composition is 6% tannin, 5% wax and 5% ash and other compounds. Cork material has heat insulation properties and sound insulation /
It has excellent sound absorption characteristics and extremely high corrosion resistance. Cork has mechanical strength due to the properties of lignin that strengthens the tissue. Cork wood has excellent chemical resistance due to the property of cellulose which is hardly decomposed, and also has excellent insect and mold-proof properties due to the properties of tannin which strongly binds to proteins.

[0017] The carbonized cork material is produced by using cork crushed into granules and powdered cork as raw materials, mixing these materials, and heating. The granular cork generates a solid intermediate by expanding the granular structure by burning the powdery cork and by being mutually connected by a resin generated from the cork itself. The solid intermediate is cooled by jetting and supplying cooling water from a nozzle of the cooling water injection device to the inside thereof, and is subjected to a pressurizing process of applying an appropriate pressure to a predetermined density. Formed. The carbonized cork material is formed into a panel shape by slicing the block-like solid intermediate thus produced at an appropriate thickness. The carbonized cork material has a large granular structure and has sufficient elasticity and heat insulating properties.

Although the carbonized cork panel 3 is laid in order on the concrete slab 4, it is not necessary to fix the laying with an adhesive if it is for a general household.
When the folding apparatus 1 is used in a place such as a place where many people gather or a tatami corridor, the carbonized cork panel 3 is firmly mounted on the concrete slab 4 using an ordinary commercial woodworking adhesive. It is also effective to fix it. Unnecessary portions around the corners and columns of the carbonized cork panel 3 are cut using a cutter and a ruler. The carbonized cork panel 3 is relatively lightweight, and can be easily installed without requiring specialty.

The tatami apparatus 1 has a two-layer structure by laying a carbonized cork panel 3 on a concrete slab 4 to form a carbonized cork base layer, and laying the main tatami mat 2 in a predetermined arrangement on the carbonized cork base layer. Of the floor.
Therefore, the tatami device 1 has a sufficient function such as a fall safety, a walking property, a heat insulating property or a heat insulating property required for the floor material. The tatami device 1 ensures sufficient air permeability between the main tatami 2 and the concrete slab 4 and ensures the transmission of moisture between the main tatami 2 and the concrete slab 4 due to the above-described characteristics of the carbonized cork panel 3. And deodorizing effect.

The tatami mat device 1 repels pests such as house mites and keeps the dry state of the tatami mat 2 by the insect repellency and air permeability of the carbonized cork panel 3, thereby suppressing the occurrence of pests. The tatami device 1 ensures that the ventilation function of the main tatami mat 2 is sufficiently exhibited, and air purification or the like is performed by supplementing nitrogen dioxide for adjusting the humidity in the room. Tatami device 1
Is composed of the main tatami mat 2 and the carbonized cork panel 3, which are natural materials, so that no toxic gas is generated even when incinerated. Therefore, the processing of the tatami device 1 is easily performed even when the tatami device 1 is old and is discarded.

Incidentally, in the tatami apparatus 1 described above,
Although the carbonized cork panel 3 is laid directly on the concrete slab 4 to form the carbonized cork base layer, the present invention is not limited to such a configuration. Since the carbonized cork panel 3 is slightly brittle due to the above-described properties of carbonized cork, it is rubbed with the main tatami mat 2 to generate cork powder. For this reason, the tatami apparatus 1 allows the fine cork powder to pass through the main tatami 2 and generate dust in the room, enter the main tatami 2 at the time of rebuilding, turning over or drying the tatami mat, or on the concrete slab 4. The trouble is that you have to deal with the accumulated cork dust.

Therefore, in the tatami mat apparatus according to the present invention, the dustproof treatment may be applied to the carbonized cork panel 3 as in the other embodiments shown in FIGS. In addition, although each embodiment is described below, the main tatami mat 2, the carbonized cork panel 3, and the concrete slab 4 are the same as those of the first embodiment.
The embodiment is the same as that of the first embodiment, and the description thereof is omitted by attaching the same reference numerals.

The tatami apparatus 10 shown in FIG. 3 is characterized in that the carbonized cork panel 3 is entirely wrapped with, for example, Japanese paper 11 which is excellent in air permeability and is relatively strong. Therefore, the tatami device 10 is used for the Japanese paper 1
1 prevents the peripheral portion of the carbonized cork panel 3 from being chipped or the like, and the carbonized cork panel 3 and the main tatami mat 2
And the generation of cork powder due to rubbing is suppressed. The tatami mat 10 has a carbonized cork panel 3 made of Japanese paper 1
1 prevents the cork powder from scattering. In addition, the Japanese paper 11 may be appropriately replaced, for example, when performing a replacement work or a reverse construction. Moreover, the tatami apparatus 10 is not limited to the Japanese paper 11 as a package of the carbonized cork panel 3, but preferably has sufficient air permeability and mechanical properties.

The tatami apparatus 20 shown in FIG. 4 is constructed by simply laying the above-described Japanese paper 11 between the main tatami 2 and the carbonized cork panel 3. It can be suppressed sufficiently. Of course, Japanese paper 1
As for No. 1, it may be bonded to the surface of the carbonized cork panel 3 by an adhesive so as not to shift.

Further, the tatami mat 30 shown in FIG. 5 employs a carbonized cork panel 32 having a surface treated with a reinforcing layer 31 for improving mechanical strength and suppressing scattering of cork powder. Features. Of course, the tatami mat device 30 may wrap the carbonized cork panel 32 with the above-described Japanese paper 11 or the like or lay it on the surface.

In each of the above embodiments,
Although the case where the tatami apparatus is applied to a concrete building has been described, it is needless to say that the tatami apparatus is also applied to a detached house and other buildings.
