Description

Detailed Description of the Invention

  According to the present invention, an upward inclined surface is formed on at least one side of a tatami made of a layered tatami flooring core material which is laminated with plastic corrugated cardboard having rigidity in a thickness direction and having flexibility in a thickness direction. The present invention relates to a barrier-free tatami mat that can smoothly get on and off on an inclined surface, and that can be used around water in a bathroom or the like without causing an elderly person to trip on the inclined surface.

  For example, in Patent Document 1, the slope between the tatami mat and the floor surface is reduced without the user being particularly conscious by incorporating inclined members on any one to four sides of the peripheral part in the manufacturing process of the tatami mat. However, there is described a tatami mat having an inclined shape at an end that can be installed more safely.

  In the present invention, as shown in FIG. 1 and FIG. 2, the cut portion of the tatami floor of the insulation board or other various materials that are usually used is made of a material having a certain degree of surface strength such as a wooden or resin. Paste the molded sloped material, or use the one that chamfered the end of the tatami floor, and wrap them together using a surface material made of materials such as natural rush or Japanese paper, fiber, “Tatami is finished by sewing or bonding” [0007].

  However, in the present invention, since it is not a layered tatami floor core material in which at least plastic corrugated cardboard having rigidity in the plane direction and having flexibility in the thickness direction is not laminated, the inclined surface is hard and there is no flexibility in the thickness direction. Therefore, since it is impossible to get on and off the wheelchair softly, rattling and vibration are likely to occur on the inclined surface. In addition, it is not suitable for use because of poor drainage around water in a bathroom.

  Patent Document 2 discloses a synthetic resin foam containing rod-like calcium carbonate having a cross section of an unequal right triangle, a veneer being pasted on the longest side of the cross section, and no veneer being stuck 2 There is described a barrier-free gradient material for placing tatami mats which is adhesively coated on both sides or one side.

  The slanted material of the present invention can be easily cut by a cutter or the like and the length can be adjusted. It is explained that the plate is attached and the adhesive processing is performed on both or one of the two sides where the veneer is not attached [0003].

  However, although it is stated that the unequal right-angled triangular rod-shaped calcium carbonate-containing synthetic resin foam of this device is simply flexible, the wheelchair got on and off the inclined part because it does not have rigidity in the plane deflection. Sometimes, on the contrary, it is too flexible and a step is formed, and the foot tip is easily caught by the step. Moreover, the action of the inclined surface is not clear because the veneer of the inclined surface is not described for what purpose and what kind of material is described. Furthermore, since plastic corrugated cardboard is not used, the drainage of the inclined part is poor, and it is not suitable for use around water in a bathroom or the like.

  Patent Document 3, Patent Document 4, Patent Document 5, Patent Document 6, Patent Document 7, Patent Document 8, and Patent Document 9 describe a frame element having an inclined surface provided around a tatami mat, a tatami parting edge, and the like. However, it is composed of a layered tatami floor core material laminated with plastic corrugated cardboard that has rigidity in the direction of thickness and flexibility in the thickness direction, and an inclined portion for use around water in a bathroom etc. There is no mention of using plastic cardboard with good drainage.

  According to the present invention, an upward inclined surface is formed on at least one side of a tatami made of a layered tatami flooring core material which is laminated with plastic corrugated cardboard having rigidity in a thickness direction and having flexibility in a thickness direction. An object of the present invention is to provide a barrier-free tatami mat that can smoothly get on and off an inclined surface, and that can be used around water in a bathroom or the like without causing the elderly to stumble on the inclined surface.

Means to solve the problem

    According to the first aspect of the present invention, at least one side of a tatami made of a layered tatami flooring core material laminated with at least plastic corrugated cardboard having rigidity in the plane direction and having flexibility in the thickness direction is inclined from the upper surface to the lower surface of the tatami mat. Provided is a barrier-free tatami having an upward inclined surface.

  In this invention, it is a layered tatami floor core material in which plastic corrugated cardboard having rigidity in the plane direction and having flexibility in the thickness direction is laminated, and an upward inclined surface is formed on at least one side of the tatami mat. A barrier-free tatami mat that can be used to get on and off the sloping surface softly, and can be used around the water in a bathroom, etc. Can be provided.

  The invention according to claim 2 is a barrier-free material according to claim 1, wherein the plastic corrugated cardboard is a layered tatami floor core material obtained by laminating foamed polypropylene having planar flexibility and flexibility in the thickness direction. It provides tatami mats.

  In the present invention, since the foamed polypropylene having flexibility in the thickness direction is laminated on the plastic cardboard, the plastic cardboard can be prevented from being broken or damaged without being directly applied to the plastic cardboard. You can get on and off the surface more softly.

  Furthermore, the invention of claim 3 provides the barrier-free tatami according to claim 1 or 2, wherein a plastic cardboard is laid on the upper surface of the upward inclined surface.

  In the present invention, since the plastic cardboard is laid on the upper surface of the upward inclined surface, it is possible to get on and off the inclined surface more softly without causing a step due to the wheelchair due to this difficulty and flexibility. It is possible to prevent breakage of the layered tatami floor core material of the inclined portion in which the plastic corrugated cardboard or the like is laminated without causing the elderly to trip on the inclined surface.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a barrier-free tatami 1 according to an embodiment of the present invention, wherein 2 is an inclined surface, 3 is a tatami table, and 4 is a tatami edge.

  FIG. 2 is a cross-sectional view taken along the line I-I in FIG. 1. The barrier-free tatami 1 has a plasticity in the thickness direction and has a flexibility in the thickness direction, and has a flexibility in the thickness direction. Layered tatami floor core material 7 which is laminated and bonded alternately with foamed polypropylene 6 having flexibility in the thickness direction, and the plastic corrugated cardboard 5 has its end facing the inclined surface. By layering, it is used as a tatami for barrier-free with good drainage from an inclined surface by using it around water in a bathroom or the like. Since the tatami mat 3 is formed with a large number of stitches in which resin yarns are knitted, the water from the plastic corrugated cardboard 5... Is easily discharged to the outside of the inclined surface through these stitches. The embodiment of FIG. 2 is particularly suitable for a thin barrier-free tatami structure.

  In this way, the plastic corrugated cardboard 5... Having rigidity in the plane deflection and flexibility in the thickness direction has the plane flexibility and the foamed polypropylene 6... Having flexibility in the thickness direction. By using the laminated tatami floor core material 7 as a laminated material, the foamed polypropylene 6... Is a cushioning material for the plastic cardboard 5. As a result, cracks and breakage can be prevented, and the wheelchair can get on and off the inclined surface more softly.

  FIG. 3 shows another embodiment corresponding to FIG. 2, in which the barrier-free tatami 11 has a plastic cardboard 15b between two foamed polystyrenes 18a and 18b having fragile plasticity, and a plastic on the upper part of the upper foamed polystyrene 18a. It is composed of a tatami floor 20 in which cardboard 15a is laminated, foamed polypropylene 16a is laminated on the upper plastic cardboard 15a, and foamed polypropylene 16b is laminated on the lower part of the lower foamed polystyrene 18b.

  Also, at least one side of these two expanded polystyrenes 18a and 18b is provided with a plastic corrugated cardboard 15... Having a plane bending rigidity and flexibility in the thickness direction, as in FIG. Side layered tatami flooring cores 17 and 17 are provided, which are alternately laminated and bonded with foamed polypropylene 16... Having flexibility and flexibility in the thickness direction. A separate plastic corrugated cardboard 19 is laminated on the upper surface of the cut surface obtained by cutting the layered tatami floor core materials 17 and 17 into an inclined shape, and the tatami surface 13 is covered with the plastic corrugated cardboard 19 and the foamed polypropylene 16a.

  In this way, the plastic corrugated cardboard 15... Has rigidity in the plane direction and has flexibility in the thickness direction. The foamed polypropylene 16... Has plane flexibility and has flexibility in the thickness direction. By using the layered tatami floor core materials 17 and 17 laminated with each other, the foamed polypropylene 16... Is used as a cushioning material for the plastic cardboard 15. It is possible to prevent breakage and breakage due to direct impact on the load of a wheelchair or the like, and the wheelchair can get on and off the inclined surface more softly.

  Further, since the two foamed polystyrenes 18a and 18b having plasticity that is easily broken are also inside the layered tatami flooring cores 17 and 17, the layered tatami flooring cores 17 and 17 are not directly burdened. As a cushioning material, it is possible to prevent cracking and breakage of the expanded polystyrene 18a, 18b due to a heavy impact, and the wheelchair can get on and off the inclined surface more softly.

  Furthermore, by stacking plastic corrugated cardboards 15 ... 19 on the inclined part, it is used around the water in a bathroom or the like to provide a barrier-free tatami mat with good drainage from the inclined surface. Since the tatami surface 13 is formed with a large number of stitches in which resin yarns are knitted, the water from the ends of the plastic cardboard 15... Is easily discharged outward through these stitches. The embodiment of FIG. 3 is suitable for a barrier-free tatami structure having a relatively large thickness. In the above embodiment, the inclined surface is formed on one side of the tatami mat, but it may be formed over 2 to 4 sides or the entire circumference. Moreover, it is good also considering the tatami edges 4 and 4 side as an inclined surface.
