DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight thin tatami mat laid on a wooden floor or the like, and to a thin tatami mat which does not substantially warp and a method of manufacturing the same.

[0002]

2. Description of the Related Art In recent years, the number of Japanese-style rooms has been decreasing with the westernization of life. In particular, due to the spread of flooring, the use of traditional tatami mats and Japanese-style rooms is decreasing. However, the texture of tatami mats is still widely preferred, and the tatami mats may be placed in one corner of the flooring. However, the conventional straw tatami was thick and heavy, and handling was difficult.

[0003] When tatami mats are laid in a large hall at an inn or an exhibition hall, the conventional tatami mats are difficult to operate flexibly according to the purpose of the room. Although required, thin tatami mats are usually prone to warping.

In recent years, in order to simplify the manufacturing process, a tatami mat back sheet, a tatami mat surface, and the like are attached to a tatami floor by stapling the end of the tatami from the back side of the tatami floor. However, in the case of a thin tatami mat, the staples may protrude to the front side when stepping on the end, and may cause an unexpected injury.

[0005]

As described above, the conventional tatami mat is quite heavy, and the size of the tatami mat is about 180.times.90 cm. In particular, when many tatami mats are laid in a hall such as an exhibition hall, there is a problem that much labor is required. Also, if the tatami floor is made thinner for weight reduction, the tatami will be warped during use, which is not suitable for practical use.

Further, the conventional tatami mat has a thickness of 50 to 60 mm, and a step of 50 to 60 mm occurs between the floor surface and the tatami surface. Therefore, there is a possibility of causing an accident such as falling down of the elderly or the like, and measures are required.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a thin tatami mat which is less likely to be warped. Therefore, the thin tatami mat according to claim 1 is a tatami mat made by laminating one or more wooden fiber boards or synthetic resin boards, and the opposite ends of the back sheet arranged on the front and back of the tatami mat floor. It is formed by inserting a part into a ring-shaped object formed by binding.

According to a second aspect of the present invention, in the thin tatami mat according to the first aspect, the back sheet is formed of a plurality of strips arranged in parallel with each other at a predetermined interval.

According to a third aspect of the present invention, in the thin tatami mat according to the first or second aspect, the synthetic resin plate of the tatami floor is a hollow laminated plate or a foamed synthetic resin plate.

[0010] According to a fourth aspect of the present invention, there is provided a method of manufacturing a thin tatami mat.
One or a plurality of wooden fiber boards or synthetic resin boards are laminated to form a tatami floor, and then a ring-shaped object is formed by binding opposite ends of a tatami mat and a back sheet arranged on the back of the tatami mat. In which the tatami floor is inserted.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a thin tatami mat according to an embodiment of the present invention has a tatami floor in which one or a plurality of components 1 made of a wood fiber board or a synthetic resin board are laminated. 2 is formed by inserting into a ring-shaped object 5 formed by binding opposing ends of a tatami table 3 and a back sheet 4 disposed on the back surface of the tatami floor 2.

As shown in FIG. 2, the front and back of the tatami mat 3 and the back sheet 4 are previously bound by means such as bonding or sewing. As shown in FIG. 3, when the tatami floor 2 is composed of a plurality of components 1, these components 1 are simply laminated without bonding or sewing each other. When the constituent material 1 includes a synthetic resin plate, the synthetic resin plate is preferably formed of a hollow laminated plate or a foamed synthetic resin plate. As for the thin tatami mat,
Is inserted into the ring-shaped object 5, and the edge is finished by bonding or sewing. In addition, as shown in FIG. 4, the back sheet 4 may be constituted by a plurality of strips 4a arranged in parallel with each other at a predetermined interval.

As a method of inserting the tatami floor 2 into the ring-shaped object 5, in the case of a plurality of sheets, the tatami floor 2 may be inserted one by one or may be inserted collectively. Since the ring-shaped object 5 is composed of the front and back of the tatami mat 3 and the back sheet 4, the tatami mat 2 is slightly elongated, and the tatami floor 2 is inserted after insertion.
Has the function of tightening.

Next, a specific embodiment will be described. First, a tatami mat 3 having a thickness of 2.5 mm, three components 1 made of a plastic corrugated cardboard (hollow laminated board made of synthetic resin) having a thickness of 5 mm, and a back sheet 4 having a thickness of 1 mm are prepared. Tatami table 3
Used is a JAS (Japanese Agricultural Standards) first-class product. Kanecapradan (trade name) manufactured by Kanegafuchi Chemical Industry Co., Ltd. is used as the plastic corrugated board of component 1. As the back sheet 4, a back sheet for tatami made of polypropylene is used.

In this embodiment, as described above, since the three plastic corrugated cardboard plates constituting the component 1 are not sewn to each other, the tatami floor 2 does not warp or be dimensionally distorted due to the tightening of the tatami thread. . Although illustration is omitted because it is a well-known technique, finishing is performed by stabbing tatami edges on both sides of the thin tatami mat and performing reverse stitching. By the above procedure, a thin tatami mat having a weight of 3 kg and a warpage of 0 mm was completed.

The weight of the thin tatami mat was measured with a JIS first class balance. As shown in FIGS. 5 and 6, the warp of the tatami mat was measured by measuring the maximum amount H of the warped portion by attaching a warp yarn 7 on the diagonal line of the thin tatami mat 6. In addition, the warp yarn 7 is shown by a dotted line in FIGS.

Next, as a comparative example, a 2.5 mm thick tatami mat table, three 5 mm thick plastic corrugated cardboard boards (synthetic resin hollow laminated boards), and a 1 mm thick Prepare the back sheet. Then, the back sheet, the three plastic cardboard boards, and the tatami mat are sequentially laminated. In this case, the three plastic corrugated cardboard boards were bonded together to be integrated according to a general tatami mat, and the tatami mat side was adhered to the front side of the tatami mat and the back sheet was adhered to the back side of the tatami mat using a double-sided tape or an adhesive. .

In this state, the facing frame portions of the front and back of the tatami mat and the back sheet are bonded and sewn using an adhesive or the like to form a thin tatami mat. After that, as in the above embodiment, the tatami mat was provided and finishing was performed.
The amount of warpage became 20 mm in a week, which was unsuitable for practical use.

In the above embodiment, the tatami floor 2 is constituted by a plurality of synthetic resin hollow laminated boards, but the tatami floor 2 may be formed by a foamed synthetic resin board or a wood fiber board. A plurality of these constituent materials 1 may be stacked vertically.

[0020]

According to the thin tatami mat according to the first aspect, a tatami mat floor formed by laminating one or more wood-based fiberboards or synthetic resin boards is bound to the opposite ends of the tatami mat front and back sheets. Since it is formed by inserting it into a ring-shaped object, it can be manufactured without the number of manufacturing steps and labor required to sew the tatami floor, and in addition, it is a thin and lightweight thin tatami mat and warp etc. A thin tatami mat without adverse effects can be easily manufactured.

According to the thin tatami mat of the second aspect, in the configuration of the first aspect, the back sheet is made of a plurality of strips arranged in parallel with each other at a predetermined interval. We can save.

According to the third aspect of the present invention, in the configuration of the first or second aspect, the tatami floor includes a synthetic resin plate, and the synthetic resin plate is a hollow laminated plate or a foamed synthetic resin plate. The advantage that the foot contact becomes good is obtained.

According to the method for manufacturing a thin tatami mat according to the fourth aspect, one or a plurality of wood-based fiberboards or synthetic resin boards are laminated to form a tatami floor, and the tatami mat and the back of the tatami mat are successively formed. Since the thin tatami mats are manufactured by inserting the tatami mats into a ring-shaped object formed by binding the opposite ends to the back sheet to be arranged, even if the tatami mats are composed of a plurality of components, There is no need to glue or sew them together, and it is not necessary to sew the tatami mat and the tatami floor together, so that the number of manufacturing steps can be reduced. Further, when the tatami floor is composed of a plurality of components, these are not connected to each other by bonding or sewing, so that the warp of the thin tatami mat can be reduced.
