Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to tatami mats. More specifically, the present invention relates to a thin tatami mat that has sufficient shape-retaining property and stability in use, and also has good cushioning property and restoring property.

[0002]

2. Description of the Related Art Heretofore, various lightweight structures have been proposed which are easy to lay and maintain, and which are made of elastic plates as thin tatami mats, for example, synthetic resin foams. It is known that an insulation board is used as an elastic plate and a tatami mat is arranged on it, and a hard plywood is laminated on the insulation board and a tatami mat is arranged on it.

These are intended to be lightweight by using an insulation board and have improved heat insulation and heat insulation properties, and are provided as being convenient in terms of installation and maintenance.

[0004]

However, in the case of the tatami using the elastic plate provided so far, there are still many problems to be solved. For example, in the case of a tatami mat having the tatami mat (a) as the tatami mat (a) shown in FIG. 12 (a) and the tatami mat (a) arranged on the upper surface, the tatami mat is absorbed by moisture as shown in FIG. 12 (b). The floor (a) stretches and warps and twists of the tatami mat occur, pushing up the adjacent tatami mat and damaging the tatami mat (a).
As shown in (c), the tatami mat shrinks due to moisture drying and compression, causing swelling of the tatami mat (b), warping and twisting of the tatami mat, and easy formation of gaps between tatami mats. The occurrence of such an abnormality is shown in FIG.
Although it can be shown in (b), in either case, the feeling of walking is deteriorated as a change in size and shape in a dry, humid, and cold environment, and deterioration of the tatami itself cannot be avoided. Moreover, the occurrence of gaps between tatami mats and the rise of tatami mats due to the pushing up of adjacent tatami mats forms a pool of dust and dust, which contributes to the inhabitation of molds and mites, and even damages the health of consumers. Becomes

Further, the tatami floor (a) sinks deeply and, together with its deterioration, makes the walking feeling worse, and the deterioration of the tatami floor (a) also impairs heat insulation and heat insulation performance. As a countermeasure against such a problem, as shown in FIG. 14A, an insulation board (C) and a plywood (D) are laminated to form a tatami floor (A), and a tatami mat (A) is placed on the tatami floor. Although a tatami mat with a plywood is also proposed, in this case, due to the existence of the plywood (d) as a hard and rigid plate, the trouble caused by the shrinkage of the insulation board (c) due to the moisture drying can be avoided. However, as shown in FIG. 14 (b), the extension due to moisture absorption causes warping and twisting of the tatami mat, and pushes up the adjacent tatami mat due to the expansion of the tatami mat outer dimensions. And
Due to the difference from the expansion rate of the tatami mat, the tatami mat is given excessive tension and is not deteriorated. As a result, the feeling of walking becomes poor, which causes tripping and falling accidents, and greatly reduces the life of the tatami mat.

Further, in the conventional tatami mat, deterioration of the tatami mat, such as sunburn and abrasion, is a serious problem, and it is aesthetically pleasing.
In addition, it often interferes with walking. And
In the case of any conventional type of tatami as described above,
At the time of laying tatami mats or during maintenance, contact resistance with adjacent tatami mats increases due to dimensional changes and shape changes due to moisture absorption, drying, etc., so it is not always easy to lay them in a predetermined position. It was

Therefore, the drawbacks of these conventional tatami mats are eliminated, the dimensional expansion and contraction is suppressed under dry and humid conditions, and the size and shape retention are stable, and the performance of the tatami mat and the tatami mat is harmonized. In addition, the laying of the tatami mat has excellent durability, aesthetics, and walkability.
It has been desired to realize an improved lightweight thin tatami mat with good maintenance workability.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Now, embodiments of the tatami of the present invention will be described below in more detail with reference to the accompanying drawings.

[0012]

1 and 2 of the accompanying drawings are cross-sectional views illustrating an AA cross section and a BB cross section of a tatami having the entire appearance of FIG. 3 as an embodiment of the present invention. First, FIG.
As is clearer, in this tatami mat, the tatami floor (1) has the hard surface rigid thin plate (1) as the upper surface, and the elastic plate (12) is attached thereto.
Is laminated to form a main core material, and a moisture-proof layer (13) is arranged and integrated on the front and back surfaces of the laminated main core material. The upper surface of the tatami floor (4) is Shorter cutting dimension than tatami floor (4) upper surface dimension, eg 0.5-2 mm
A tatami mat (116) having a relatively short length is arranged, and a tatami edge (117) made of a synthetic resin woven cloth covers the end surface on the tatami floor (1) side, and the back surface thereof is fixed by staples (118), and the fixation The part is covered with a tape (119) attached. Further, in the example of FIG. 1, these different materials are integrated by the sewing thread (14).

In such a structure, first, in FIG.
As in the case of FIG. 1 shown as a section A, the tatami mat (1
16) Since the tatami mat (116) having a short cutting size is attached to the upper surface of the tatami mat (1) at the side end portion orthogonal to the fiber, the rush of the tatami mat (116) itself has a margin in the longitudinal direction. Even if the component of the tatami mat, for example, the elastic plate (12) expands and contracts more than the tatami mat (116) due to changes in humidity and humidity,
The tatami mat (116) can be prevented from bulging. Therefore, the swollen portion of the tatami mat (116) is prevented from being worn out and worn extremely quickly.

Therefore, there is no hindrance due to floating, swelling, or waviness, and the durability, aesthetics, and walking feeling are excellent. Further, the tatami mat (117) is made of synthetic resin woven cloth, which is sewn and integrated, so the synthetic resin fiber woven cloth is resistant to sunburn discoloration and has abrasion resistance against abrasion and the like. Since it is good, it has high durability (life). Moreover, it dries quickly and is easy to clean. In addition, it can be sewn on, and it suppresses floating, swelling, and waviness, and has an excellent aesthetic appearance and walking feeling.

Then, as shown in FIG. 1, the productivity is high due to the method of fixing the staples (118) on the back side of the tatami floor (1) of the tatami mat (117), and by temporarily attaching the tape (119). Prevents the staples from floating, prevents rust, and prevents exposure. The above-mentioned excellent effects are obtained on the tatami floor (1)
It becomes more prominent by being synergized with the effect of the characteristic constitution of.

Regarding the tatami floor (1), the hard surface-stiffness thin plate (11) is a resin such as veneer plywood, bamboo knitting board, polypropylene hard foam so that the tatami floor has an appropriate surface rigidity. The elastic plate (12) may be a plate or the like, and as the elastic plate (1), an appropriate surface elasticity is given to the tatami floor (1).
Insulation boards, olefin resin foams such as polypropylene and polyethylene, polystyrene foams and the like can be used. The moisture-proof layer (13) provided on the front and back surfaces of the tatami floor (1) may be a sheet or film made of synthetic resin such as polyethylene or polypropylene or wax-treated kraft paper, or an elastic cushion. .

Basically, in the case of the tatami floor (1) of the present invention having the above-mentioned constitution, the moisture-proof layer (13) is arranged and integrated, which is essentially different from the conventional one. Has a big feature. By arranging the moisture-proof layer (13) on the uppermost surface of the tatami floor, the moisture-proof layer (13) has a hard surface rigid thin plate (11) having a small coefficient of wet-heat linear expansion and a small expansion coefficient in the lower part thereof. Since the tatami mats are arranged, the size and shape retention of the tatami upper surface can be stabilized against changes in dry and wet temperatures and cold temperatures. Even with respect to the local load, the local rigidity is suppressed by the surface rigidity of the hard surface rigid thin plate (11) and the surface is deformed, and the elastic plate (12) supports and suppresses the lower part to restore it. Become. In that sense, the elastic plate (12) retains an appropriate surface elasticity.

Further, in the tatami floor (1) of the present invention, since the moisture-proof layer (13) serves as an outside air barrier coating layer, not only is moisture absorption suppressed, but dust adhering / removing property is improved and dust and dirt are removed. It will be sealed to prevent scattering and deter the infestation of mold and mites. It will protect the health of consumers. As described above, the moisture-proof layer (13) on the surface may be an elastic cushion, for example, an elastic cushion such as polyethylene foam or urethane rubber foam, in which case the sole of the foot is shallow (for example, 0.5 when the walking load is applied). By using a cushion layer that sinks (about 2 mm), it is possible to obtain the effect of reducing the walking impact load and making it less slippery. In addition, it absorbs the unevenness of the floor base surface and prevents the surface step and floating after finishing the tatami laying. When the moisture-proof layer (13) made of an elastic cushion is arranged on the back surface of the tatami floor (1), the optimum tatami for RC floor concrete floor laying is realized in addition to the above-mentioned action, while walking. There is little rattling of the floor and vertical movement of the floor finish surface.

The moisture-proof layer (13) may have a skin layer on one side, and the skin layer may be the outer surface of the main core material. By doing so, the adhesion of dust and dirt on the back side of the tatami mat is improved and the cleanability is improved, and the tatami mat is well maintained. In addition, the habit of mold and mite will be suppressed. As described above, in the case of the example of FIG. 1, the threads are integrated by the sewing thread, but by doing so, the hard surface rigid thin plate (1) that constitutes the tatami mat (116) and tatami floor (1) is formed.
1), the elastic plate (12) and the moisture-proof layer (13) can be independently expanded and contracted without interfering with each other by making the dimension expansion and contraction take advantage of the inter-layer lubricity and displacement action while being in close contact with each other. To do. Therefore, it is possible to realize a composite tatami mat which is excellent in shape retention stability and does not warp or deform due to dimensional expansion and contraction even under changing environmental conditions such as dry and humid conditions.

Of course, not only is the sewing thread integrated,
It goes without saying that sticking or other means can be appropriately adopted depending on the installation conditions and the like of the tatami mat. In the tatami floor (1) as an example of the present invention, as shown in FIG. 1, a hard surface rigid thin plate (11) and an elastic plate (12) constitute a main core material, and a moisture absorbing layer ( One of the preferable examples is that 13) is provided and laminated with, for example, a sewing thread (14) and the outer peripheral edge side surface thereof is provided with an inclined chamfered portion (4) facing downward. There is.

FIG. 4 exemplifies a state in which a tatami mat whose outer peripheral side ends are chamfered in an acute angle is laid, and adjacent tatami mats are in contact with each other at the chamfered parts. As is clear from FIG. 4, when a chamfered tatami floor is used, the area of the contact portion between adjacent tatami mats becomes small, and the frictional contact resistance due to the vertical movement of the tatami mats during installation is small. In addition to facilitating tatami laying and tatami work, the joint joint can be made more beautiful, and the chamfered part (4) prevents the push-up and the gap caused by the dimensional expansion and contraction after laying. Can be absorbed by.

As shown in FIG. 5, the inclination of the side end portion by chamfering brings about the effect of absorbing the dimensional expansion and contraction even in the tatami floor which does not have the moisture-proof layer (13). For example, FIG.
Even if the elastic plate (12) extends due to moisture absorption as shown in (b), the inclination absorbs the dimensional change of the elastic plate (12) so that the outer dimension (A) of the tatami itself hardly changes.

Therefore, as described above, the moisture-proof layer (13)
In the case of providing, the action and effect on such changes in size and shape are further synergistically large. And
2 is a sectional view taken along line BB of FIG. 3 in the embodiment of the present invention.
As shown in Fig. 11, on the side surface of the end of the tatami mat (116) parallel to the fibers, the tatami mat (11) is formed at the notch (8) on the back surface.
6) and the tatami edge (117) are attached and fixed by a staple (118), and an adhesive tape (119) is arranged at this fixing portion.

By accommodating the tatami mat (116) and the tatami edge (117) in the notch (8), the relationship between the lower surface of the tatami floor (1) and the floor base is improved, and the space between the lower surface of the tatami floor (1) is improved. In addition, the effect of minimizing the deflection and vertical movement during walking load due to floating can be obtained. Regarding the tatami floor (1) for use in the present invention, a moisture-proof adhesive tape (100) is attached to the side surface of the outer peripheral end portion thereof, for example, as shown in FIG. 111) is also effective, and as shown in FIGS. 8 and 9, it is also effective to cover by impregnation or application of a moisture-proof synthetic resin. By these means, it is possible to suppress contact with the outside air at the side end portion of the tatami floor, and to suppress dimensional expansion and contraction and thickness change due to moisture absorption and desorption. Therefore, the manufacturing and distribution process,
Also, the fluctuation of humidity throughout the year is suppressed, and the management of manufacturing and storage conditions becomes easy.

An elastic body may be used for the moisture-proof pressure-sensitive adhesive tape (100) and the moisture-proof film (111). By elasticity,
It is possible to absorb dimensional expansion and contraction when laying a tatami mat, and it is easy to adjust dimensional variations during tatami mat production. Further, as for the tatami floor (1), as shown in FIGS.
By using 2) as a porous material having communication holes at the top and bottom, it is possible to realize a tatami floor with excellent heat retention and heat insulation, and also sound absorption. Of course, the weight can be reduced. It is useful as a tatami floor for floor heating. By filling the voids of the porous material with activated carbon, it is possible to simultaneously purify air while conducting heat transfer and convection. Then, to explain further, in the example of FIGS. 1 and 2, the adhesive tape (119) is stapled (118).
The adhesive tape (119) is provided at the fixing portion, but by using this adhesive tape (119) also as a slip preventing function, an overlay tatami mat for a wooden floor can be realized. There is no displacement or movement, and it can be used laid down.

Further, as illustrated in FIG. 11, a sheet-like support (121) in which needles (120) made of hard synthetic resin are arranged substantially vertically is fixed to the back surface of the tatami floor (1). Thus, a tatami for laying laying on a carpet made of fiber can be realized with the displacement and movement suppressed. Of course, the present invention is not limited by the above examples. Various aspects are possible in dealing with the details.

[0027]

As described in detail above, according to the present invention, as a thin tatami mat, it has sufficient cushioning and restoring properties in use, good shape retention, and no problems such as steps or floating. A tatami mat is provided that is easy to manufacture and install.
