Description

[Detailed Description of the Invention] The present invention relates to the improvement of hard floor mats such as wood fiber floor mats and hard foam resin floor mats.

Recently, tatami floors made of natural wood fiber boards or tatami floors made of hard foam resin boards have been proposed to replace tatami floors made of rice straw.

The above-mentioned tatami flooring has advantages over tatami flooring made of rice straw, such as being free from dust mites, having excellent durability, and being able to be laid directly on concrete floor surfaces.

However, tatami floors made of wood fiber boards or foamed resin boards are much harder than tatami floors made of rice straw, which is a fatal drawback for tatami mats whose life depends on the feeling of stepping on the soles of the feet.

In order to give the tatami floor appropriate cushioning properties, there are methods such as lowering the degree of compression of the wood fiber board or increasing the foaming rate of the resin board, but in either case, there is a problem that the pressure resistance of the tatami floor decreases. be.

The present invention provides a tatami mat that solves the above problem by interposing a specially designed cushion sheet between the tatami floor and the tatami face.

The present invention will be specifically described below based on embodiments shown in the drawings.

The tatami floor 1 of the tatami mat in this embodiment is made of a well-known wood fiber board made by cutting wood fibers into a board shape and hardening it by drying and heat treating it at high temperatures, but is not limited to this. It may also be formed by laminating a resin board or a hard foam resin board and a wood fiber board.

A moisture-proof sheet 2 is provided on the lower surface of the tatami floor 1, and a cushion sheet 3, which is a feature of the present application, is provided on the upper surface and sewn 6 to the tatami floor 1.

The cushion sheet 3 is made by adhering and polymerizing a thin, air-permeable thin synthetic resin film 5 such as polyethylene film or polypropylene on one side of a paper sheet 4, and then embossing it, that is, an uneven pattern, as shown in FIG. The sheet is passed between a resilient roll 8 or plate and a resilient roll 81 or plate to form an uneven pattern on the entire surface of the sheet.

The height 30 of the cushion sheet 3 in this embodiment is approximately
It is 1.5 to 2 mm.

Place the cushion sheet 3 with the paper sheet 4 facing up.
The tatami floor 1 is covered with the cushion sheet 3, and the tatami cover 7 is stretched over the cushion sheet 3 to complete the tatami.

When a person's weight acts on the tatami, the cushion sheet 3 is pressed, and the unevenness of the sheet is deformed to create cushioning properties, giving the soles of the feet the same comfortable stepping sensation as straw tatami. .

When the load is removed from the cushion sheet 3, the unevenness of the sheet returns to its original state, and the cushion action continues for a long period of time.

Since the cushion sheet 3 of the present invention has a synthetic resin film 5 polymerized and bonded to the paper sheet 4 to increase the mechanical strength of the sheet 4, the thickness of the paper sheet 4 is limited to the thickness of the cushion sheet 3 made of only the paper sheet. The thickness is less than 1/3 of that of the conventional method, making it economical.

Furthermore, since the synthetic resin film 5 itself is made of a thin and breathable material, the cushion sheet 3 is breathable, and furthermore, needle holes (not shown) are punctured when it is sewn onto the tatami floor 1, making it difficult to wear shoes. The cushion sheet 3 does not block the air permeability of the wood fibers, and therefore does not impair the moisture absorption and moisture release characteristics of the tatami floor.

Furthermore, the synthetic resin film 5 has greater resistance to sewing needles than the paper sheet 4. Therefore, contrary to this embodiment, if the cushion sheet 3 is sewn with the synthetic resin film 5 facing upward, that is, if the sewing needle first penetrates the synthetic resin film 5, a large force is required to insert the sewing needle. It takes.

In contrast, in this embodiment, the paper sheet 4 is facing upward and the sewing needle first penetrates the paper sheet 4, so that the needle that has penetrated the paper sheet easily pierces the synthetic resin film 5 due to inertia, and the sewing is completed. It's easy.

The cushion sheet 3 may be made by polymerizing a thin synthetic resin film 5 on both sides of a paper sheet 4, or may have a sandwich structure in which the synthetic resin film 5 is sandwiched between two thin paper sheets. It can fulfill the purpose of imparting cushioning properties.

As described above, the present invention has a simple structure in which the cushion sheet 3 is interposed between the tatami floor 1 and the tatami surface 7, and can provide a comfortable stepping feeling to the soles of the feet.

Furthermore, the cushion sheet 3 is inexpensive because it can be easily and efficiently produced by embossing a paper sheet 4 with a synthetic resin film 5 polymerized thereon. Furthermore, the tatami floor 1 has many excellent practical effects, such as the fact that conventional wood fiber board or foam resin board can be used without deterioration of durability and pressure resistance.
