Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a lightweight and thin tatami mat using a foamed resin body.

[0002]

[Prior art]

 Traditionally, tatami mats have been made of straw as the core and igusa as the tatami mat, and as an improved model, wood fiber board or foam is sandwiched with plywood, aluminum plate or plastic plate, or plywood with plastic plate or praddan ( Some are sandwiched with plastic cardboard.

[0003]

[Problems to be solved by the device]

 Traditional tatami mats are heavy and inconvenient to handle, and have a thickness of 55 mm to 60 mm, so there is a step between the Western-style room and the Japanese-style room, which is not safe to use. In addition, the floor surface of the Japanese-style room must be lowered in order to eliminate the steps, which is a constraint on the design.

In the case of a house made of concrete, the entire floor surface becomes high and the indoor space becomes narrow. In addition, they become a hotbed for mites and lice, which is not good for health.

In the case of using the improved plywood or the like, since the plywood and the wood fiber board or the foam material of the core material are bonded by using an adhesive, it is possible to prevent expansion and contraction of the plywood due to indoor drying and humidity. However, it does not fit well with the foam, so that not only peeling of the plywood but also warpage occurs.

Furthermore, if the wood fiber board and the plywood are thin, they have poor elasticity as tatami mats, but if they are thick, a difference between the Japanese-style room and the Western-style room occurs. Furthermore, since wood fiber boards and plywood absorb and release moisture, if the tatami-mat is stretched strongly, warping or swelling of the tatami-mat will occur, and if it is moderately stretched, wrinkles will form on the tatami-mat.

[0007] In addition, the tatami mat shrinks during drying, resulting in a gap between the tatami mats and a cause of tatami mat breakage.

[0008] Normally, when a tatami mat is stretched, the tatami mat is stretched while warping the tatami mat, and the tatami mat is stretched after the tatami mat is stretched. It is not possible to work such as bending back.

[0009] Furthermore, since the front side of the tatami is formed wider than the back side so that no gap is created between the tatami mats after the tatami mats are fitted, and the tatami mat is pushed in with a strong force for construction, the bending strength Is required. However, since the conventional structure also lacks this bending strength, the fitting work cannot be performed easily. On the other hand, the aluminum plate has a strong advantage in expansion and contraction and bending, but it is troublesome because it cannot be sewn in the process of manufacturing a tatami mat or cut with a knife such as a kitchen knife.

Therefore, in the improved type, the cost is high, and after the construction, there is a gap between the tatami mats, and dust, mites, lice, etc. enter between them, which is not hygienic and unclean. .

[0011]

[Means for Solving the Problems]

 Therefore, the present invention provides a fiber reinforced thermoplastic resin body that is lightweight and thin, has bending strength, elasticity, warpage, pressure resistance, and compression strength, and that can be sewn and cut with a blade during manufacturing. It was manufactured by using the laminated molding used as a tatami core. This makes it possible to manufacture tatami mats with a thickness of 12 mm to 20 mm, and it is possible to provide a safe tatami flooring without creating a step between a Western-style room and a Japanese-style room.

[0012]

[Embodiment of the invention]

 Next, the present invention will be described according to an embodiment shown in the drawings.

As a tatami core 1, a laminated molding in which a fiber-reinforced thermoplastic resin sheet 3 in which fibers are laminated in a thermoplastic resin with directionality is welded to the front and back surfaces of a rectangular foamed resin body 2. Using the product, igsa 4 was stretched on the surface, both ends in the longitudinal direction were slightly wound to the lower side of the stile, and tatami mats were attached to both side edges in the longitudinal direction by a known method and sewn. .

By using a molded product in which fiber materials are laminated, the present invention can manufacture a tatami mat having the same performance as a conventional tatami mat with a thickness of 20 mm or less, and it is possible to eliminate a step between a Western-style room and a Japanese-style room. . Furthermore, since it can be fixed to the tatami core by sewing, it is possible to deal with the difference in expansion and contraction between the surface igusa and the resin molding of the tatami core, which prevents the surface igsa from sagging and rising.

Further, according to the present invention, a hard plate such as plastic or iron, an angle material, or a U-shaped material is arranged in the stile corner of the tatami core, and the corner is reinforced at an acute angle. There is therefore no slack. Even in the case of the thin tatami flooring of the present invention, the corners do not have obtuse angles or roundness, and therefore, there is no dent between the tatami mats that are constructed, so that the tatami mat construction can be performed well.

When the fiber-containing thermoplastic resin body of the present invention was tested by the particle board test method (JISA-5908), the bending strength was 10 mm, the bending strength was 100 kg / cm ² , and the bending elastic modulus was 20,000 kg / cm. ^2, 25 mm bending thick strength 30 Kg / cm ^2, shows a sufficient elasticity and flexural modulus 2,000 kg / cm ^2.

[0017]

【Example】

 A non-woven cloth 6 is laminated on the surface of a laminated molded article 1 in which polypropylene molded sheets obtained by laminating glass fibers aligned in one direction are laminated on the front and back surfaces of a polypropylene 15-fold expanded rectangular body, and the igsa 4 was coated.

A plastic or iron plate, or an angle member or a U-shaped member was arranged as a reinforcing member 7 on the upper surface at the corner of the laminated molded product.

[0019]

[Effect of the invention]

 The product of the present invention does not impair the performance of the traditional straw-core tatami mat, has excellent bending strength, pressure resistance, and compression strength, and therefore has no warpage. Above all, it can be thinned and is the same as a flooring. The height can be increased and the difference between the Japanese-style room and the Western-style room can be removed. This also makes the floor of the tatami part low to remove the step, but such a design is unnecessary.

In terms of manufacturing, the tatami core of the laminated molded product can be easily sewn and cut, and is easy to manufacture.

Further, in terms of construction, the product of the present invention has bending strength, so that the tatami mat can be easily fitted, and there is no possibility that a gap between the tatami mats after the mating will occur.

Furthermore, since the tatami core of this laminated molded product does not contain nutrients, it is possible to provide a sanitary tatami mat without worrying about mites and harmful insects.

Furthermore, by arranging the reinforcing material at the corner of the tatami core, it is possible to provide a tatami having a good appearance in which the tatami mat is not loosened after being stretched or dented between tatami mats.
