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 of 10 to 30 mm in which a tatami mat and a tatami mat floor are fixed with staples.

[0002]

2. Description of the Related Art In general, tatami mats in which natural rush is attached to a tatami floor specified by Japanese Industrial Standards (JIS) are frequently used. Tatami mats stipulated by Japanese Industrial Standards (JIS) use a core material made of a combination of insulation board, polystyrene foam, straw material, etc. as a basic core material. Uses a 50 to 55 mm thick tatami floor fitted with a protective material.

[0003] In addition to rush, which is a natural material, tatami mats are made of woven fabrics made of processed resin products, woven fabrics made of processed paper products, and the like. For fixing the tatami floor and the tatami mat, it was fixed by conventional thread sewing, but in recent years, fixing using staples,
The so-called stapler is frequently used.

[0004] On the other hand, a living space using a tatami mat requires a barrier-free function such as no step between a Japanese-style room and a Western-style room.
There is a demand for a function capable of changing the pattern between a Japanese-style room and a Western-style room. As a result, a tatami mat having the same thickness as the flooring material of the Western-style room, that is, a thin tatami mat having a thickness of 10 to 30 mm has been required.

[0005]

The material composition of the thin tatami mat is basically the same as that of the thick tatami mat (55 to 60 mm), but the thickness of the tatami mat is extremely thin, 5 to 25 mm, and staples are hard to stop. It is difficult to fix the tatami mat. Further, since the needle point of the U-shaped staple is suitable for a tatami mat surface, that is, a so-called tatami mat use surface, there has been a problem that the risk of injury to a person is increased.

[0006]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a new thin tatami mat having a thickness of 10 to 30 mm, which eliminates the danger of fixing stability and danger when the tatami mat and the tatami mat are fixed with staples. . That is, the present invention relates to the following (1) to (3). (1) When the tatami table is rolled from the end of the tatami floor along the side of the tatami floor to the back side of the tatami floor, and the tatami table and the tatami floor are fixed from the back side of the tatami floor with U-shaped staples, the staples are used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. Generally, staples are driven in a sealing machine. There are commercially available sealing machines, for example, a manual type or an automatic type such as a Tachikawa hand sealing machine TSH-18 type.
It is not necessary to use a new one in particular. However, as shown in FIG. 3, the U-shaped staple has a portion having a horizontal portion (a) and both ends (a), (a) of the horizontal portion (a). (B), (b ') where the needle tip extends perpendicularly from (b), and the original positions from the positions (b) and (b') from the needle tips (b) and (b '), respectively. It is necessary to provide a mechanism formed by portions (c) and (c ′) in which the angles (θb) and (θb ′) are bent by 45 ° or more inside. The angles (θa) and (θa ′) are usually 90 °, but 90 °
There is no particular problem even if it is formed below.

Next, as shown in FIG. 2, the materials of the tatami mat are the tatami mat (1), the core material (4), the cushion materials (6) and (6 ').
And a protective material (7). The material of the tatami mat (1) is
Natural rush, processed paper, or processed synthetic resin is used.

Next, in the present invention, the staple (5) is wound around the tatami mat and fixed to the tatami mat with the core (4) retaining the mechanical strength of the tatami mat. In addition, when a tatami mat is usually mounted, the tatami mat is stretched while warping the tatami floor, so that a constant tension is always applied to the tatami mat, and a core material capable of withstanding the pulling force of the staple is preferable.

However, as the structure of the core material (4), a material that does not hinder the bending of the staple needle tip and that damages the plate-like body (9) at the time of bending is preferable. Accordingly, the material of the plate-like body (9) is made of an insulation board or a polystyrene foam, and one side of the plate-like body (9) is used.
Alternatively, a sheet having a thickness of 0.1 to 0.5 mm made of glass fiber and polypropylene resin that are continuous in
Or a laminated sheet (8), (8) having a thickness of 0.2 to 1.0 mm in which glass fibers are integrated so as to be orthogonal to each other.

EXAMPLES The present invention will be described below with reference to examples. Production example [Production of tatami floor] As a plate-like body (9), a 10-fold expanded polystyrene foam (a milite board manufactured by JSP) with a thickness of 7 mm is used, and a glass fiber that is unidirectionally continuous with a polypropylene resin on both surfaces thereof. The core material (4) is obtained by bonding and integrating one laminated sheet (8), (8 ′) (Preglon LF15 / KX15 manufactured by Mitsui Chemicals, Inc.), which is integrated so as to be orthogonal to each other. A non-crosslinked 20-fold foamed polyethylene sheet (Miramat S manufactured by JSP) having a thickness of 2 mm is used as cushioning materials (6) and (6 '), and a protective material (7) is provided on the back side with a thickness of 0.5 mm (JIS Z1533). The tape yarn is a single type of tape yarn specified in JIS P3401 and woven in a plain weave with a density of 10 yarns / 25.4 mm in both length and width and pressure-bonded to three types of kraft paper specified in JIS P3401).

[0013] The tatami floor thus constructed is processed by a conventional tatami floor manufacturing machine using sewing threads such as vinylon tatami thread specified in JIS L2501 in the same manner as the building material tatami floor.
The thickness of the tatami floor finished in this configuration is 12 mm.

Example 1 The tatami floor manufactured in the manufacturing example was cut into a width of 100 mm × a length of 300 mm, and a tatami table (natural rush, 1st class product specified in Japanese Agricultural Standards) from the back of the tatami floor
The staple is wound around about 0 mm and staples for a U-shaped sealing machine (needle width 35 mm × needle tip length 18) using the sealing machine (hand sealing machine TSH-18 manufactured by Tachikawa) described in the present invention.
mm) from the back side of the tatami floor to the center located in the width direction.

At this time, the shape of the staple that has been driven is such that the angles (θa) and (θa ′) are determined from the portion having the horizontal portion (a) and both ends (a) and (a ′) of the horizontal portion (a). Is 9
The part where the needle point extends vertically at 0 ° (b), (b ')
And a certain position (b) from the needle point (b), (b ')
From (b ′), it was confirmed that the angles (θb) and (θb ′) were composed of portions (c) and (c ′) bent at 135 ° from the original position.

Further, to evaluate the staple pull-out durability of the obtained sample, a spring scale was attached to the tatami table and the tatami table was pulled vertically, and the tensile load until the staples came off the tatami floor was measured. Load 1
The staples do not come off even at the time of 00N,
It was confirmed that the tatami mat and the tatami mat floor were completely fixed.

COMPARATIVE EXAMPLE 1 In the same manner as in Example 1, using an air tucker machine (AH-1212 manufactured by Tachikawa), each of the U-shaped staples (needle width: 12 mm) was set to a needle tip length of 4 mm. 6m
m and 8 mm one by one and fixed.

When the three types of samples obtained were measured in the same manner as in Example 1, the staples came off the tatami floor. Table 1 shows the types of the samples and the results of the tensile load when the staples came off the tatami floor.

Example 2 In accordance with the present invention, a tatami floor constructed according to the production example was finished to a thickness of 15 mm using a conventional tatami mat (using natural rushes, a first-class product specified in Japanese Agricultural Standards) and edge materials. (Standard size between Kanto, width 880 mm × length 1760 mm) was manufactured. The finished thin tatami mat had no problems such as looseness and wrinkles on the tatami mat surface, and had a good finish.

Next, in order to evaluate the adaptability of the replacement of the tatami mats, the staples driven into the thin tatami mat are removed with metal fittings, the tatami mats are detached, and the tatami mats are replaced with new ones. The experiment of repeatedly fixing the tatami floor with staples was repeated. Since the damage to the core material of the tatami floor is extremely small, it was confirmed that the tatami mat and the tatami floor were completely fixed, the finish of the thin tatami mat was good, and the tatami mat could be replaced at least three times.
