Abstract

PROBLEM TO BE SOLVED: To prevent a tatami facing from being displaced from a tatami padding by bonding the tatami facing to the surface of the tatami padding and bonding a non-woven fabric to the rear side of the tatami facing in a thin tatami mat having the tatami facing on the tatami padding. SOLUTION: A thick sheet 2 is provided on the underside of a core material 1 and a moisture-proof paper 3 is provided on the underside of the sheet 2, and a cushioning material 4 comprising an expanded polyurethane sheet is bonded to the upper surface of the material 1. And the material 1, sheet 2, paper 3 and material 4 are sewn together by means of a sewing thread 9 to form a tatami padding 9 and a non-woven fabric 6 is bonded to the underside of the padding 9, following which an end of a tatami facing 7 is sewn is to the underside of the padding 9 and an adhesive 8 is applied to the upper surface of the material 4 to bond the facing 7 to the surface of the padding 9. Thus a warp, twist, and distortion are prevented from being produced in the padding.

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, since the standardization of quality and the factory production can be easily performed, the manufacturing cost 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 problems, and an object of the present invention is to provide a thin tatami mat which can prevent a tatami mat from being displaced from a tatami floor.

[0006]

In order to achieve this object, in the present invention, in a thin tatami mat having a tatami mat attached to a tatami mat floor, the tatami mat is adhered to the surface of the tatami mat floor.

In a thin tatami mat having a tatami floor attached to a tatami floor, a nonwoven fabric is adhered to the back surface of the tatami mat.

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. The adhesive 8 is applied in a wavy manner on the upper surface, and the tatami mat 7 is adhered to the surface of the tatami floor 9 with the adhesive 8.

In this thin tatami mat, the tatami mat 7 is adhered to the surface of the tatami mat 9, so that the tatami mat 7 does not shift with respect to the tatami mat 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.

In the present embodiment, the adhesive 8 is applied to the surface of the tatami floor 9 in a wave shape, but the adhesive may be applied to the entire surface of the tatami floor 9. The area on the surface of the tatami floor 9 to which the adhesive is applied may be the entire area of the surface of the tatami floor 9, and the areas 10 at both ends in the longitudinal direction of the thin tatami mat shown in FIG.
The tatami mat 7 may be adhered to the surface of the tatami mat floor 9 only in the area 10 by applying an adhesive to the tatami mat 7 only.

FIG. 4 is a schematic front sectional view showing a part of another thin tatami mat according to the present invention. As shown in the figure, the end of the tatami mat 11 is attached to the back of the tatami mat 9 by sewing.
The nonwoven fabric 12 is adhered to the back surface of.

In this thin tatami mat, the nonwoven fabric 12 is adhered to the back surface of the tatami mat 11, and the nonwoven fabric 12 has a property of not easily expanding and contracting.

The area of the back surface of the tatami mat 11 to which the nonwoven fabric 12 is adhered may be the whole area of the front surface of the tatami mat floor 9, or the tatami mat 11 of the area 13 at both ends in the longitudinal direction of the thin tatami mat shown in FIG.
The nonwoven fabric 12 may be bonded only to the back surface of the nonwoven fabric.

[0014]

When the tatami mat is adhered to the surface of the tatami mat like the thin tatami mat according to the present invention, the tatami mat does not shift with respect to the tatami mat floor.

Further, when the nonwoven fabric is adhered to the back surface of the tatami mat, the nonwoven fabric has the property of not easily expanding and contracting, so that the tatami mat does not shift with respect to the tatami floor.
