Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tatami floor, a method for manufacturing the same, and a tatami mat. Specifically, the present invention relates to a tatami floor formed by laminating natural materials such as rice straw in multiple layers, a method for manufacturing the tatami floor, and a tatami mat including the tatami floor or a tatami floor manufactured by the manufacturing method .
[0002]
[Prior art]
Since ancient times, tatami floors with multiple layers of rice straw have been used. This tatami floor uses rice straw, so it has excellent hygroscopicity (humidity control) and good health, but on the other hand, it is hygroscopic and hygroscopic, so if it is not frequently dried, moths and ticks are generated. It also has the disadvantage of being easy to do. However, since the tatami floor of rice straw is heavy, it is difficult to dry the insects, and there is a problem that it is not easy to secure a place for drying the insects in the city.
[0003]
For this reason, in recent years, stylo tatami mats using chemicals such as expanded polystyrene have been provided. This Styro Tatami mat has no hygroscopicity, so there is no need to dry insects to dry the inside.However, because it lacks hygroscopicity, it is suitable for the generation of moths and ticks in a highly airtight environment like a recent house. Will give. For this reason, a styro-tatami mat with antibacterial and insecticidal treatments is also provided, but since this treatment is based on chemicals, it is considered that the human body may show a hypersensitive allergic reaction.
[0004]
Japanese Utility Model Laid-Open No. 6-47476 discloses a tatami mat having a pest repellent or antibacterial wood powder formed between a tatami mat and a tatami floor in the form of a sheet. Here, “formed in a sheet shape” means “a structure in which wood powder is sandwiched between two sheets” or “a structure in which wood powder is formed into a sheet shape with a resin”. In addition, examples of wood flour include hiba, sawara, cypress, and yaksugi.
[0005]
Japanese Utility Model No. 3033933 discloses a tatami floor that is provided with moisture absorption and desorption (humidity control) by integrally providing a wooden board formed by pressing and heating small pieces of wood on both sides of a carbonized cork board.
[0006]
[Problems to be solved by the invention]
In the tatami mat of Japanese Utility Model Publication No. Hei 6-47476, there is no special mention of the tatami floor. If a tatami floor similar to the Styro tatami mat is used in the tatami mats of this publication, the tatami floor and the floor surface below the tatami floor are used in a highly airtight environment such as a recent house because it lacks hygroscopicity. It seems that there will be a problem that wrinkles are likely to occur between the two. In addition, if rice tatami mats are used, it is likely that there will be a problem that cocoons and ticks are likely to be generated inside the tatami mats in a highly airtight environment such as a house in recent years.
[0007]
In the tatami floor of the actual No. 3033933 gazette, a wooden board is integrally provided on both sides of the carbonized cork board, and therefore lacks elasticity compared to the traditional rice straw tatami floor. For this reason, it is considered that the accumulation of fatigue in human bone tissue and the like due to long-term use increases. Moreover, since it suppresses generation | occurrence | production of a tick and a moth indirectly by provision of moisture absorption / exhaust (humidity control), it is thought that the effect is also inferior to the case where an antibacterial / insect control treatment is performed.
[0008]
The present invention can give a good effect on health by giving moisture absorption / exhaust (humidity control) to the tatami floor, exhibiting sufficient antibacterial and insect repellent effects without causing an allergic reaction, and a natural feeling of use. and to provide a mat having a Tatamiyuka and manufacturing methods having elasticity obtained, a tatami floor produced by the Tatamiyuka or the production method.
[0009]
[Means for Solving the Problems]
The invention of claim 1 is formed by laminating cocoon layers composed of cocoons arranged in parallel so that the arrangement directions of adjacent cocoon layers intersect , and between the cocoon layers , insecticidal and / or antifungal medicinal effects. It is a tatami floor characterized by interposing a wood piece layer formed by laying a single plate formed by slicing wood having a thickness of 0.2 to 0.6 mm .
Examples of straw include rice straw, but are not limited to rice straw. It is possible to use dried natural plant fibers having a certain length, such as wheat straw and dried bamboo leaves.
Examples of the wood having an insecticidal and / or antifungal medicinal effect include cypress, hiba, sawara, camphor, yakusugi, eucalyptus and the like.
[0010]
The invention of claim 2 is characterized in that, in the above-mentioned configuration, the wood piece layer is formed by laying the veneer and mixing wood sawdust having insecticidal and / or antifungal medicinal effects. The floor.
The invention of claim 3 is formed by slicing wood having insect repellent and / or fungicidal medicinal effects to a thickness of 0.2 to 0.6 mm on a reed layer in which dried reeds are arranged in the first direction. A single plate is laid down to form a piece of wood, and on the piece of wood, a cocoon layer in which cocoons are arranged in a second direction intersecting with the first direction is provided. And / or laying a veneer of sliced wood having a medicinal effect of antifungal to a thickness of 0.2 to 0.6 mm to form a piece of wood, and on the piece of wood, the first direction A tatami floor with a total thickness of about 6 cm after compressing the total thickness to about 1 m by performing a predetermined number of steps of alternately laminating the cocoon layers and the wood piece layers, such as providing a cocoon layer in which cocoons are arranged Is a method of manufacturing a tatami floor.
The number of cocoon layers is not particularly limited. However, if the number of layers is increased (= thinning the thickness of one layer ) and each piece of wood is provided between each cocoon layer, insecticidal and / or antifungal effects are obtained. , Even more uniformly throughout the tatami floor.
The invention according to claim 4 is formed by slicing wood having insect repellent and / or antifungal medicinal effects to a thickness of 0.2 to 0.6 mm on a reed layer in which dried reeds are arranged in the first direction. A single plate is laid down to form a piece of wood, and on the piece of wood, a cocoon layer in which cocoons are arranged in a second direction intersecting with the first direction is provided. And / or laying a veneer of sliced wood having a medicinal effect of antifungal to a thickness of 0.2 to 0.6 mm to form a piece of wood, and on the piece of wood, the first direction After performing a laminating process for providing a cocoon layer in which cocoons are arranged in a total thickness of about 1 m, the total thickness is about 6 cm by compression, and the thickness of the lowermost cocoon layer is 1 to 1.5 cm, The thickness of the wood piece layer above it is 0.5-1 cm, the thickness of the cocoon layer above it is 1.5-3 cm, the thickness of the wood piece layer above it is 0.5-1 cm, The thickness of the straw layer to obtain a tatami floor 0.5 to 1.5 cm, a method for producing a tatami floor, characterized in that.
When a single piece of wood having a thickness of 0.2 to 0.6 mm is laid down as in the constitution of claims 1 to 4 , the insecticidal and / or antifungal medicinal components are gradually introduced from the surface of the single plate. Therefore, the divergence period can be extended. In addition, the diverging period can be adjusted to a desired period by adjusting the thickness of the single plate. For example, when the thickness of the single plate is about 0.3 mm to 0.5 mm, the tatami floor can be easily cut and a sufficient divergence period can be obtained. In addition, when the area of the veneer is sufficiently wide (eg, when the area is the same as the area of the tatami mat, in this case, the thickness may exceed 0.5 mm, the stiffness increases as the thickness increases) The work of laying the single plate between the cocoon layers becomes easy and the workability is improved.
When the sawdust is mixed and used as in the configuration of claim 2, since the surface area of each sawdust is large, the amount of the insecticidal and / or antifungal medicinal component divergence per unit time becomes large, and sufficient insecticide And / or the antifungal medicinal effect can be obtained. Another advantage is that sawdust as industrial waste can be used. That is, when Ru used together pieces of wood veneer and sawdust, it is possible to obtain the synergistic effect of the above two.
[0011]
The invention of claim 5 is a tatami mat provided with a tatami floor having any one of the above-mentioned configurations , or a tatami mat provided with a tatami floor manufactured by any one of the above-described manufacturing methods . In other words, the tatami mat is formed by stitching a tatami mat table made of a known material such as Reed grass on the upper surface of any of the above tatami floors.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be specifically described with reference to the drawings.
FIG. 2 shows a Japanese-style room in which the tatami mat 20 according to the present embodiment is placed. Shoji 50 is used in this Japanese-style room.
[0013]
As shown in FIG. 1 (b), the tatami floor of the tatami 20 is a lowermost cocoon layer 21 formed by arranging well-dried rice straw ("twist" laid for more than one year) 200 in the B direction. A large number of cypress single plates (a single plate sliced to a thickness of about 0.2 mm to 0.6 mm, preferably about 0.3 mm to 0.5 mm) 23a are laid on the top surface of the cypress, and cypress sawdust 23b Mixing together to make the lower wood piece layer 23, the rice straw 200 dried to the same extent as the rice straw 200 of the lowermost straw layer 21 is arranged in the A direction (direction perpendicular to the B direction). In the same manner as the lower wood piece layer 23, a cypress veneer 23a and sawdust 23b are arranged on the upper surface to form the upper wood piece layer 23, and the uppermost wood piece layer 23 is disposed thereon. An upper straw layer 21 is provided, which is formed by arranging rice straws 200 dried in the same direction as the rice straw 200 of the lower straw layer 21 in the B direction. Formed by compression in the pressure.
[0014]
The total thickness is about 1 m before compression, but the total thickness is about 6 cm after compression. The thickness of each layer after compression is 1 to 1.5 cm for the lowest cocoon layer 21, about 0.5 to 1 cm for the lower wood piece layer 23, and 1.5 to 3 cm for the intermediate cocoon layer 25. The upper wood piece layer 23 is about 0.5 to 1 cm, and the upper eaves layer 21 is about 0.5 to 1.5 cm.
[0015]
On the upper surface of the tatami floor constructed as described above, a tatami table created using cocoon grass is stitched with hemp-based stitches at its edges, and the seams are formed on the fabric edge 29 as shown in FIG. Covered. Thereby, the tatami 20 is constituted.
[0016]
In the tatami 20 constructed in this way, the medicinal ingredients gradually emanating from the surface of the cypress veneer 23a and the medicinal ingredients quickly emanating from the surface of the cypress sawdust 23b are divided into upper and lower cocoon layers 21, Since it is fully diffused in 25 and 21, it has a sufficient antifungal and insect repellent effect. In addition, since its medicinal effects are not due to chemical agents, it does not cause hypersensitive allergic reactions in the human body.
[0017]
In addition, because it is made up of multiple layers (rice straw layer 21, straw layer 25, straw layer 21) using rice straw 200, it has sufficient moisture absorption and drainage (humidity control), and it has It is possible to provide a healthy indoor environment even in a highly airtight environment. In addition, because it is made up of multiple layers of rice straw 200 (salmon layer 21, persimmon layer 25, persimmon layer 21), it is rich in natural elasticity, and can be used for many years in the bone tissue of the human body. It is possible to minimize the accumulation of fatigue due to impacts.
[0018]
The above-described configuration is an example, and the thickness of each layer and the number of stacked layers are arbitrary. When the thickness of each cocoon layer is reduced and the number of layers is increased, the penetration of the medicinal component into each cocoon layer becomes even quicker. Further, in the above, the single plates are spread and the sawdust is mixed and used together, but only the single plates may be used. When used in combination with small-angle's, together with penetration of medicinal ingredient is rapidly, can be advantageously utilized sawdust is industrial waste as a raw material. When only a single plate is used, the problem that sawdust scatters at the time of manufacturing (when laying and compressing) can be solved. In addition, when a large-area single plate is used, the labor for arranging on the upper surface of the ridge layer can be reduced, and the workability in manufacturing can be greatly improved.
[0019]
Moreover, although the case where the single board and sawdust of cypress are used is described above, the same effect can be achieved even with hiba. In addition, the present invention can be applied to any wood having medicinal components such as Yakusugi, camphor, and eucalyptus.
Moreover, although the case where rice straw is used is described above, the same effect can be achieved with wheat straw. In addition, the present invention can be similarly applied to dried plant fibers having a certain length such as bamboo leaves.
[0020]
Next, the shoji 50 will be described.
As shown in FIG. 3 (a), the shoji 50 includes a plurality of vertical and horizontal frames in a frame composed of vertical rods 51, 51 and upper and lower horizontal beams 53 (the lower horizontal beam is not shown). A vertical bar 55 is provided so that the outer end surface of the vertical rod 51 is in close contact with the vertical pillar built in the house as shown in FIG.
[0021]
The characteristic point of the shoji 50 is the three-layer structure of the vertical gutter 51. That is, as shown in FIG. 3 (b), the vertical gutter 51 includes an outer end portion 51a which is a surface in contact with a vertical column of a house, a core portion 51b which is a central portion of a three-layer structure, and a crosspiece 55. A three-layer structure is formed with the inner end portion 51c which is the surface on the side supporting the. In addition, decorative plates 51d and 51d made of a material having high design properties are attached to the front surface facing the room side and the back surface facing the hallway side.
[0022]
The outer end 51a is a plate and is made of a material rich in design. The core portion 51b is a grid and is made of a mud material. The inner end 51c is a plate and is made of mulberry material. Thus, since it is set as the three-layer structure of a plate-a grid-plate, stress is disperse | distributed and there exists an effect by which curvature is relieve | moderated.
[0023]
The outer end 51a is made of wood having a good design for improving the appearance, and has a certain thickness (lateral length in FIG. 3B). Therefore, when setting the shoji 50 to the house, even if there is a backlash between the vertical pillars of the house, both sides can be removed by shaving the surface of the outer end 51a. Can be intimate. That is, even when the surface of the outer end portion 51a is scraped off to a small thickness, the core portion 51b with poor design is not exposed. Such an effect can be achieved even when the core 51b is composed of any one of a laminated material, fiberboard, parallel plywood, or orthogonal plywood.
[0024]
In the example shown in FIG. 3B, the outer end 51a has a thickness of about 10 to 30 mm, the core 51b has a thickness of about 10 to 30 mm, and the inner end 51c has a thickness of about 10 to 30 mm. The thickness 51d (the thickness in the depth direction in the figure) is about 0.5 to 2.0 mm.
The outer end 51a, the core 51b, and the inner end 51c may be made of, for example, cypress, cedar, hiba, etc. for the interior material, and Lawson cypress (rice bran), spruce, hiba for the exterior material (rice material). Pine, etc. can be used. Further, the core 51b can also be constituted by a laminated material, a parallel plywood, an orthogonal plywood, a particle board, an MDF, or the like.
[0025]
【The invention's effect】
According to the present invention, since a straw made of natural materials such as rice straw is used for the tatami floor, it has moisture absorption / exhaust (humidity control) and natural elasticity. For this reason, it is good for health, and accumulation of fatigue in bone tissue and the like due to long-term use can be sufficiently reduced. Also, since the straw layers is interposed a repellent and / or pieces of wood layer which is constructed by laying a single-plate formed by slicing to a thickness 0.2~0.6mm timber having antifungal efficacy, allergy A sufficient antifungal and insect repellent effect can be achieved without fear of inducing a reaction.
