Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tatami mat that has excellent cushioning properties, breathability, repeatability, water absorption, and the like.

[0002]

[Prior art]

 Recent tatami mats that use foamed synthetic resin (generally called a chemical floor) for the tatami mat and have a board layer on top of it tend to lack softness (cushioning). To compensate for this drawback, a cushion sheet was provided as a cushioning material between the tatami floor and the board layer. As shown in Fig. 3, the cushion sheet 4 has corrugated paper corrugations 8 laid so as to be parallel to the arrangement direction of the tatami mat 7 of the tatami mat 5, soft base paper, envoice liner paper, and non-woven fabric. Some of them were laid.

[0003]

[Problems to be solved by the device]

 As shown in FIG. 3, the tatami mat 1 ′ having the cushion sheet layer 4 made of corrugated paper is pressed from above as it is used, and as shown in FIG. Goes in. Finally, the compressive strength peculiar to corrugated paper is reduced by half, resulting in poor cushioning and repeatability, poor appearance, and short life. In addition, soft base paper has a very poor cushioning property, and embossed liner paper and non-woven fabric have poor breathability, and the cost is high.

In view of the above problems, the present invention has an object to provide a tatami mat that has excellent cushioning properties, breathability, repeatability, etc., is inexpensive, is easy to assemble, and has sufficient durability. I am trying.

[0005]

[Means for Solving the Problems]

 The present invention takes the following technical means in order to achieve the above object.

That is, in a tatami mat in which a board layer 3, a cushion sheet layer 4 and a tatami mat table 5 are sequentially laminated on a tatami mat floor 2 made of expanded synthetic resin, the cushion sheet layer 4 is made of corrugated paper, and its corrugations 8 are formed. It is characterized in that it is laid orthogonally to the direction of arrangement of the vegetation 7 on the tatami mat 5.

[0007]

[Action]

 The cushion sheet layer 4 of the tatami mat according to the present invention is made of corrugated paper, and the corrugations 8 thereof are laid orthogonally to the arrangement direction of the weeds 7 of the tatami mat table 5, so that the weeds 7 are formed between the corrugations 8. Since it does not enter and the shape of the corrugation 8 hardly collapses even if a considerable pressure is applied from above, it has durability to maintain cushioning, breathability, repeatability, etc., and is easy to handle. Etc. will be excellent.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, a tatami mat 1 according to the present invention comprises a tatami mat (chemical floor) main body 2 made of foamed synthetic resin, and a board layer 3, a cushion sheet layer 4, and a tatami mat 5 laminated in this order. Yes, both ends in the longitudinal direction are sewn with cloth-like tatami mats 6,6.

As the foamed synthetic resin forming the tatami mat main body 2, for example, known ones such as Styrofoam and Kanepar (both are registered trademarks), and the board layer 3 serving as a reinforcing material, for example, cardboard Known materials such as wood, veneer board, and wood fiber are used. In addition, the tatami mat 5 is also made of the same grass 7 as before.

In the tatami mat 1, between the tatami mat main body 2 and the tatami mat 5 or under the tatami mat main body 2, activated carbon fiber sheets for absorbing moisture and odors, and pests such as mites and ants are prevented. Insect repellent sheets and other sheets containing preservatives, fragrances, etc. may also be inserted.

The cushion sheet layer 4 provided between the board layer 3 and the tatami mat 5 is made of corrugated paper, as shown in FIGS. In contrast, they are laid in an orthogonal shape.

Therefore, unlike the conventional one shown in FIG. 4, the weeds 7 do not enter between the ripples 8 and the shape of the ripples 8 collapses even if a considerable pressure is applied, and one ripple 8 is formed. There is no such thing as a crush.

As described above, the corrugating process is hardly broken and the corrugated 8 shape is maintained for a long period of time. The water content of the tatami mat is large and the water content of the tatami mat is large.) It also has excellent cushioning and repeatability, giving a soft feeling to the human body and making Tatami 1 very comfortable.

In addition, even when the tatami mat 5 is attached to the cushion sheet layer 4, the corrugations 8 of the seat layer 4 are orthogonal to the arrangement direction of the grass 7 of the tatami mat 5, so that the corrugations 8 It does not interfere with the tensioning of 7 and does not leave rush 7 or wrinkles. Therefore, the tatami mat 5 of the completed tatami mat 1 looks very nice, and the damage and shrinkage after that are considerably reduced.

Further, corrugated paper is also very cheap to manufacture, unlike cost-effective liner paper and non-woven fabric.

[0017]

[Effect of device]

 The cushion sheet layer 4 of Tatami 1 is made of corrugated paper, and its corrugations 8 are laid orthogonally to the direction of arrangement of the weeds 7 in Tatami Table 5, so this Tatami 1 has cushioning, breathability, repeatability, and It has excellent water absorption, is cheap, is easy to manufacture, and has sufficient durability.
