BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami floor of a so-called chemical tatami mat mainly comprising a foamed resin plate.

[0002]

2. Description of the Related Art In Japan, a tatami mat that has been used for a long time has a structure in which a tatami mat made of grass or the like is sewn on the upper surface of a tatami floor made of straw or the like. However, such a tatami mat has a problem that the tatami floor is susceptible to corrosion due to weakness of moisture, and ticks and the like are apt to be generated. Is difficult to handle.

In recent years, various types of so-called chemical tatami mats in which part or all of the straw constituting the tatami mat are formed of a foamed resin material have been proposed and put into practical use (for example, Japanese Utility Model Laid-Open No. 1-171834). No., Jpn.
No. 6031). As described above, a tatami floor mainly made of a foamed resin plate has many advantages such as excellent moisture resistance and reduction in weight.

[0004]

However, in the above-described configuration of the tatami floor of the conventional chemical tatami mat, a foamed resin plate is used as a main material, so that the tatami mat is sewn on the surface of the tatami mat floor. When used for use, the sewing thread that is sewing between the tatami floor and the tatami mat due to slippage between the tatami mat and the tatami mat is displaced in the foamed resin layer, In some cases, the tatami mats become loose with respect to the tatami mat floor, and wrinkles are generated on the tatami mats.

The present invention has been made to solve such a problem, and it is an object of the present invention to provide a tatami floor which can prevent the tatami mat from becoming loose due to the loosening of the sewing thread during use. With the goal.

[0006]

SUMMARY OF THE INVENTION A tatami floor according to the present invention is a tatami floor mainly made of a foamed resin plate, wherein a mesh-like resin made of the same material as the foamed resin plate is provided on upper and lower surfaces of the foamed resin plate. The sheet is integrally formed.

[0007]

In the tatami floor of the present invention, since a mesh-like resin sheet is integrally formed on the surface of the foamed resin plate as the main material, the sewing thread is passed through the hollow portion of the mesh of the resin sheet. Thereby, the tatami floor and the tatami mat covering the surface of the tatami floor are sewn. Therefore, even if the sewing thread tends to shift within the foamed resin plate due to slippage between the tatami mat floor and the tatami mat surface, the sewing thread is locked to the mesh portion of the resin sheet and the sewing thread becomes The tatami mat is prevented from being loosened with respect to the tatami floor.

In the present invention, it is preferable to further laminate a resin sheet having a cushioning property on the upper surface, whereby the cushioning property of the surface can be improved.
The foamed resin plate is preferably selected from any one of polystyrene, polypropylene, polyethylene, styrene-modified polyethylene, and polyvinylidene chloride in response to demand.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific embodiments of the tatami floor according to the present invention will be described with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of a chemical tatami mat according to an embodiment of the present invention, and FIG. 2 is a partial sectional view of the chemical tatami mat of the present embodiment. . As shown,
The chemical tatami mat 1 according to the present embodiment includes a tatami mat floor 2 and a tatami mat table 4 sewn to the tatami mat floor 2 with a sewing thread 3 so as to cover a part of an upper surface, an end face, and a lower surface of the tatami mat floor 2. And a fold 5 sewn to both end edges of the long side of the tatami table 4 (only one side is shown in FIG. 1).

The tatami floor 2 is provided with a resin sheet 7, 7 having a mesh shape (hexagonal, hole area 0.7 cm ^{2 in the} illustrated example) made of polystyrene on the upper and lower surfaces of a foamed polystyrene plate 6 as a main material. A laminated body in which a foamed polystyrene sheet 8 is disposed as a resin sheet having a buffering property on the upper surface of the resin sheet 7 on the upper surface.
Here, the foamed polystyrene plate 6 has a density of 0.2 to 0.1 in consideration of hardness, cushioning property, strength, and the like.
A material having a density of 01 g / cm ³ , preferably 0.030 g / cm ³ is used.

In such a laminate, a foaming agent is blended into a mold of a foaming polystyrene molding machine in a state where the foamed polystyrene sheet 8 and the mesh-like resin sheets 7, 7 are inserted in advance in the mold. A pre-foamed polystyrene material is placed and formed by integral molding.

According to the chemical tatami 1 of this embodiment, when the tatami mat 4 is sewn on the surface of the tatami floor 2 using the sewing thread 3, the sewn thread 3 is attached to the hollow portion of the mesh of the resin sheet 7. When the chemical tatami mat 1 is in use, the sewing thread 3 may be displaced in the expanded polystyrene plate 6 due to slippage between the tatami mat floor 2 and the tatami mat table 4 during use. However, the sewing thread 3 is locked to the net portion of the resin sheet 7 to prevent the displacement. That is, it is possible to obtain the chemical tatami mat 1 having good adhesion between the tatami mat floor 2 and the tatami mat table 4.

In the chemical tatami 1 of this embodiment, even if a concentrated load is partially applied to the surface of the tatami mat 4 during use,
The presence of the resin sheet 7 on the upper surface side formed in a mesh shape also has the effect of distributing the load around the load application point along the mesh of the resin sheet 7.

Further, in the chemical tatami mat 1 of this embodiment, the tatami mat 4
Even if an impact load is applied from the side, the load can be absorbed by the expanded polystyrene sheet 8 provided on the upper surface side and attenuated accurately. Therefore, it is possible to prevent dents, cracks, and the like from occurring in the expanded polystyrene plate 6. Even if the tatami mat 4 absorbs water, the expanded polystyrene plate 6 does not absorb water and can be easily dried.

Further, since straw or the like is not used for the tatami floor 2, the weight can be reduced as a whole, and the tatami floor 2 can be manufactured easily and inexpensively, and the occurrence of ticks and the like can be prevented. .

In this embodiment, the case where a foamed polystyrene plate is used as a main material has been described. Instead of this foamed polystyrene plate, any one of polypropylene, polyethylene, styrene-modified polyethylene and polyvinylidene chloride is used. Even if two foams are used, the same operation and effect as described above can be obtained.

The mesh-like resin sheet may be a main material.
If the same material as the foamed resin sheet is used, for example, polypropylene, polyethylene, or the like can be used in addition to the above-mentioned polystyrene. By thus as the material of the resin sheet same as the main material, it becomes possible to recycle the worn tatami floor. The opening area of the mesh is
0.3-2.0cm to prevent pull-out of sewing thread
² is preferred. Further, as the resin sheet having a buffering property to be laminated on the mesh-like resin sheet, in addition to the above-mentioned foamed polystyrene sheet, a foamed sheet of a resin such as polypropylene or polyethylene, a rubber-based sheet, or the like may be used. it can.

In this embodiment, the expanded polystyrene sheet 8 disposed on the upper surface of the resin sheet 7 on the upper surface side is integrally formed with the expanded polystyrene plate 6 and the resin sheet 7. 8 may be separate from the expanded polystyrene plate 6 and the like, or the expanded polystyrene sheet 8 may be omitted.

Further, in this embodiment, the mesh shape of the resin sheet 7 is hexagonal, but various mesh shapes can be adopted. The present invention can be implemented in various other modes.

[0021]

As described above, according to the present invention, since the mesh-like resin sheet is integrally formed on the surface of the foamed resin plate as the main material, the tatami floor and the surface of the tatami floor are formed. When the covering tatami mat is sewn with the sewing thread, it is possible to prevent the sewing thread from slipping in the foamed resin plate due to slippage between the tatami mat floor and the tatami mat. Therefore, it is possible to prevent the tatami mat from being loosened with respect to the tatami floor during use. At the time of this sewing, a sewing thread is applied to the mesh-like resin sheet.
Since the hollow part can be passed, the sewing work is extremely
It can be done easily.

Even when a concentrated load is partially applied to the surface of the tatami mat at the time of use, the concentrated load can be dispersed by the resin sheet on the upper surface side formed in a mesh shape, so that the dent or the like is formed on the foamed resin plate. Cracks and the like can be prevented from occurring. Furthermore, it is integrally molded on the surface of the foamed resin plate
The resin sheet is made of the same material as the foamed resin plate that is the main material.
