Description

Detailed Description of the Invention

  The present invention relates to a water-washable tatami mat that has a feeling of elasticity similar to that of a natural rush tatami mat as a whole tatami mat without causing wrinkles even when a load is applied to the tatami mat by a human foot.

  For example, in Japanese Patent Application Laid-Open No. 2004-84198, a water flow plate having a floating portion on the lower surface is disposed on the bottom floor surface with a central layer made of a synthetic foam resin interposed therebetween, while the central layer A tatami body is formed by installing a front water-permeable plate and a fender sheet on the top and covering the surface with a tatami surface made of synthetic resin fiber rush, and the side of the tatami body perpendicular to the lash A high water-resistant tatami mat capable of bathing is described in which a tatami rim channel member is detachably fitted to the edge.

  However, in the present invention, since a synthetic resin plate having a smooth surface is not interposed between the respective foamed synthetic resins constituting the core material (center layer), a sufficient tensile force cannot be obtained in the tatami mat and the wrinkle of the tatami mat is not obtained. Occurrence cannot be sufficiently prevented. That is, the water flow plates 2, 3 and the center layer 1 do not shift with respect to the stitch direction of the tatami yarn S in FIG. 2 because they are firmly sewn, but may shift in a direction perpendicular to the stitch direction. However, even if the water flow plates 2 and 3 and the center layer 1 are displaced in this direction, the tatami mat channel 6 is fitted to the tatami side edge, and the tatami mat table 5 and the tatami mat channel 6 are Since they are not continuous and separate, the tatami mat is not affected by the tension caused by these deviations. Therefore, wrinkles that occur in the tatami mat cannot be prevented.

  Moreover, since the hard core material (center layer) is formed relatively thick at the center of the tatami mat, the tatami mat as a whole cannot have a feeling of elasticity that approximates that of natural rush mats.

  Further, since the foamed synthetic resin surfaces constituting the center layer are in contact with each other, when the foot is applied in one direction to the upper surface of the tatami mat surface, the foamed synthetic resins rub against each other and generate an unpleasant noise.

  Japanese Patent Laid-Open No. 2001-227142 includes a tatami table including plastic artificial grass, a tatami floor including a plastic core material and plastic protective sheets disposed above and below the core material, and is non-absorbent. An artificial tatami mat characterized by having it is described.

  However, since no synthetic resin plates with smooth front and back surfaces are interposed between the respective foamed synthetic resins, there is no deviation, so that a sufficient tensile force cannot be obtained on the tatami surface, and wrinkles of the tatami surface cannot be prevented. Further, since the thickness adjusting member is formed to be relatively thick, it is impossible to obtain a feeling of elasticity that approximates the natural rush tatami as a whole tatami.

Problems to be solved by the invention

  An object of the present invention is to provide a water-washable tatami mat that has a feeling of elasticity similar to that of a natural rush tatami mat as a whole without causing wrinkles even when a load is applied to the tatami mat by a human foot.

Means to solve the problem

[0009]
[Means for solving the problems]
According to the first aspect of the present invention, two foamed polystyrene core members are provided with a hollow synthetic resin plate made of plastic corrugated cardboard sandwiched between them, and the upper surface of the foamed polystyrene core material on the surface side is made of another plastic corrugated cardboard. Laminate synthetic resin tatami mats with a resin plate in between, and wash with water by stitching the synthetic resin tatami mats on the side of the foamed polystyrene core without adhering to the upper surface of the hollow synthetic resin plate made of plastic cardboard. A tatami mat is provided.

  When a force is applied to the tatami surface from one side by the sole of the foot, the hollow synthetic resin plate on the surface side slides on the top surface of the polystyrene foam core material on the surface side, and the end of the plate presses one side surface of the tatami surface in one direction. . Thereby, a tensile force works in the one direction on the front side of the tatami mat. On the other hand, when a force is applied to the tatami surface from one side by the sole of the foot, the foamed polystyrene core on the back side is pressed against the lower surface of the tatami mat by the foot pressure applied to the tatami upper surface, while the lower surface of the hollow synthetic resin plate is The end of the sliding polystyrene foam core presses the other side of the tatami mat in the other direction. As a result, a tensile force acts in the opposite direction to the above on the back side of the tatami mat. In this way, at least the front-side hollow synthetic resin plate and the back-side expanded polystyrene core material slide together in the opposite direction to press the side of the tatami mat surface, so that a tensile force is obtained on the tatami mat surface and the occurrence of wrinkles on the tatami mat surface is ensured. Can be prevented. The two front and back hollow synthetic resin plates and the two front and back foam polystyrene cores are fixed at both ends with the sewing thread, but it seems that they do not deviate, but actually there are expansion and contraction of the sewing thread, The deviation may be in a minute range sufficient to stretch the wrinkles.

  A hollow synthetic resin plate made of plastic corrugated cardboard has a corrugated hollow body and is highly elastic. On the other hand, the foamed polystyrene core material is a foam but a hard body. Therefore, two foamed polystyrene core materials are provided with a hollow synthetic resin plate made of plastic corrugated cardboard having elasticity and smooth surface, and other elastic properties are provided on the upper surface of the foamed polystyrene core material on the surface side. Since a hollow synthetic resin plate made of plastic corrugated cardboard is laminated, and two hollow synthetic resin plates made of plastic corrugated cardboard are interposed between two foamed polystyrene core materials (the thickness of the core material itself) It is possible to provide a washable tatami mat having a feeling of elasticity similar to that of a natural rush tatami mat as a whole tatami mat.

  In addition, the hollow synthetic resin plate made of plastic corrugated cardboard is smooth and slippery on the front and back surfaces, and the foamed polystyrene core material is foamed and rough on the surface, and is difficult to slip. Therefore, since these are alternately laminated, it is possible to prevent unpleasant noise that occurs when they are shifted.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. At least two foamed polystyrene core materials 2a and 2b are provided across a hollow synthetic resin plate 3b made of plastic corrugated cardboard, and a synthetic resin tatami table 1 is sewn on the surface of the foamed polystyrene core materials 2a and 2b. The tatami mat A is configured. As a result, even if a load on the tatami mat is applied by a person's foot, the foamed polystyrene core material 2a and the hollow synthetic resin plate 3a, and the foamed polystyrene core material 2b and the hollow synthetic resin plate 3b are displaced from each other. Tensile force acts on the tatami mat 1 and does not cause wrinkles. The synthetic resin tatami mat 1 uses polypropylene.

  A synthetic resin tatami table 1 is laminated on the upper surface of the foamed polystyrene core material 2a on the surface side with another hollow synthetic resin plate 3a, a synthetic resin foam sheet 4a and a deodorizing sheet 5 interposed therebetween, and the back surface core material 2b A synthetic resin foam sheet 4b is provided on the lower surface, and the synthetic resin tatami mat 1 is sewn on the side surfaces of the core materials 2a and 2b. The hollow synthetic resin plates 3a and 3b have moderate elasticity and surface smoothness, and protect the foamed polystyrene core materials 2a and 2b and prevent sound generated when they are displaced. When the foamed resins are rubbed with each other, an unpleasant noise is generated. On the tatami surface 1, a suitable flexibility can be given by the synthetic resin foam sheet 4a and the hollow synthetic resin plate 3a. The synthetic resin foam sheets 4a and 4b use foamed polypropylene, and the deodorizing sheet 5 uses a polyester sheet containing activated carbon. Further, the synthetic resin foam sheet 4b prevents slipping with the floor surface on which the tatami mat A is installed. Reference numeral 7 denotes a seam.

  Furthermore, the liquid far-infrared radiator 6 is sprayed on the back surface of the tatami surface so that the liquid far-infrared radiator penetrates into the fine eyes of the artificial rush on the tatami surface. The liquid far-infrared radiator 6 has a growing electromagnetic wave (water molecule resonance wavelength) of about 6.0 to 6.5 and has antibacterial, sterilizing and deodorizing actions. When water absorbs infrared energy of this wavelength, it changes to active water having a reducing action with a balance of negative ions, and is most effective in preventing deterioration of water quality and maintaining freshness. It is particularly effective for purifying hot water in baths.

  In the above configuration, the tatami mat has a thickness of about 30 to 55 mm and a weight of 6 kg or less per square meter. Preferably it is 5 kg or less.

The invention's effect

  As described above, in the present invention, wrinkles do not occur even when a load on the tatami mat is applied to the tatami mat, and the tatami mat as a whole has a feeling of elasticity similar to natural rush tatami mats, and has an extremely good antibacterial, sterilizing and deodorizing effect. The provided washable tatami can be provided.
