DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin tatami mat having a thickness about one-fourth that of a normal tatami mat.

[0002]

2. Description of the Related Art In a conventional thin tatami mat, an end of a tatami mat is attached to the back of a tatami floor by sewing.

In such a thin tatami mat, since the weight is small, the laying work can be easily performed. In addition, quality standardization and factory production can be easily performed, so that manufacturing costs can be reduced. In addition, since the thickness is almost the same as the thickness of carpets and flooring, even if thin tatami mats are laid together with carpets and flooring, the floor of the room can be flattened, so for people with disabilities and the elderly, It is possible to make the room easy to live.

[0004]

However, in such a thin tatami mat, since the strength of the tatami mat floor is low, the tension of the tatami mat floor cannot be increased, so that the tatami mat floor may be displaced with respect to the tatami mat floor.

[0005] The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide a thin tatami mat which can prevent a tatami mat from being shifted with respect to a tatami floor.

[0006]

In order to achieve this object, according to the present invention, there is provided a thin tatami mat having a tatami mat attached to a tatami mat floor. Composed of moisture-proof paper and cushioning material ,
Apply adhesive only to the area at both ends in the longitudinal direction of the surface.
Then, the tatami mat is adhered to the surface of the tatami mat floor.

[0007]

FIG. 1 is a schematic front sectional view showing a part of a thin tatami mat according to the present invention, and FIG. 2 is a partially cut plan view showing a part of the thin tatami mat shown in FIG. As shown in the figure, a thick paper 2 is provided on a lower surface of a core material 1, a moisture-proof paper 3 is provided on a lower surface of the thick paper 2, a cushioning material 4 made of a urethane foam sheet or the like is provided on an upper surface of the core material 1, The material 1, the cardboard 2, the moisture-proof paper 3 and the cushioning material 4 are sewn with sewing threads 5, and the core material 1, the cardboard 2, the moistureproof paper 3 and the cushioning material 4 constitute a tatami floor 9. Further, the nonwoven fabric 6 is attached to the back surface of the tatami floor 9, that is, the lower surface of the moisture-proof paper 3, and the end of the tatami mat 7 is attached to the back surface of the tatami floor 9 by sewing. An adhesive 8 is applied in a wavy manner on the upper surface, and a tatami mat 7 is adhered to the surface of the tatami floor 9 with the adhesive 8. Also, as shown in FIG. 3, both ends in the length direction of the thin tatami mat
The adhesive 8 is applied only to the area 10 of the
The tatami mat 7 is adhered to the surface of the tatami mat floor 9.

In this thin tatami mat, the tatami mat 7 is adhered to the surface of the tatami mat floor 9 so that the tatami mat 7 does not shift with respect to the tatami mat floor 9. Further, since the core material 1, the cardboard 2, the moisture-proof paper 3 and the cushioning material 4 are sewn by the sewing thread 5, the core material 1, the cardboard 2, the moisture-proof paper 3, and the temperature, humidity, pressure, aging, etc. Even if there is a difference in the amount of expansion and contraction of the cushioning material 4,
It is possible to prevent the tatami floor 9 from being warped, twisted, distorted, and swollen.

[0009]

When the tatami mat is adhered to the surface of the tatami mat floor as in the thin tatami mat according to the present invention, the tatami mat does not shift with respect to the tatami mat floor, and the core material, cardboard, moisture-proof paper and cushioning material are used. Because it is sewn with sewing thread, temperature, humidity, pressure,
Even if there is a difference in the amount of expansion and contraction of the core material, the cardboard, the moisture-proof paper and the cushioning material due to aging or the like, it is possible to prevent the tatami floor from warping, twisting, warping, bulging and the like.
