  In the above-mentioned prior literature, it is described that water-resistant tatami mats are laid in the bathroom, etc. However, generally, bathrooms are not standardized and designed like ordinary Japanese-style rooms, so tatami mats can be laid as they are. First, if the tatami cannot be laid, the tatami must be cut and laid along the tatami. It is necessary to attach a tatami edge to the cut tatami mat again, which is very laborious.

  Therefore, an object of the present invention is to provide a tatami floor structure that can easily lay tatami on the entire floor surface of a bathroom or the like and can easily perform maintenance such as replacing a damaged tatami table. Is.

  The tatami mat floor structure according to the present invention includes a plurality of water-resistant tatami core materials arranged on a laying surface, a plurality of water-resistant tatami mats covering the entire surface of the tatami core material, the laying surface, and the tatami core material. A base member provided with a wall portion provided with a foot portion disposed between the wall portion and a wall portion that is provided in a band shape along the side surface of the tatami core member and has an engagement groove formed over the entire length thereof; and And a cover member provided with a belt-like tatami rim covering the rim of the tatami core material, and an end portion of the tatami surface is the cover member. In addition, the base member is press-fitted into an engagement groove and fixed. Further, the cover member disposed on the edge of the laying surface is provided with a belt-shaped covering portion that is in close contact with the wall surface. Furthermore, the base member disposed on the drainage side edge of the laying surface is characterized in that a strip-shaped drainage portion in which a plurality of drainage holes are formed extends to the upper end.

  Since the present invention is configured to fix the water-resistant tatami surface covering the surface of the water-resistant tatami core material with the base member and the cover member by having the above-described configuration, the shape of the laying surface of the bathroom or the like is used as the tatami-core material. If the tatami surface is cut and fixed according to the tatami core material, the tatami mat can be easily laid according to the laying surface.

  In addition, the base member is arranged along the side surface of the tatami core material, and both ends of the tatami surface are press-fitted together with the engagement portion of the cover member into the engagement groove of the base member so that the tatami surface is fixed. It is possible to fix the tatami table and to stretch the tatami table in the same manner as a conventional tatami mat. And since the strip | belt-shaped tatami edge part which covers the edge part of a tatami core material is provided in the cover member, it can be set as the tatami mat floor structure which does not feel discomfort with the conventional tatami.

  Further, since the tatami mat is not integrated with the tatami core material and is fixed separately, only the tatami mat can be removed and easily replaced, and maintenance work can be easily performed.

  In addition, since the cover member disposed on the edge of the laying surface has a band-shaped covering portion that is in close contact with the wall surface, the covering portion can hide the gap at the edge of the laying surface and cover It is possible to prevent the members from shifting.

  In addition, the base member disposed on the drainage side edge of the laying surface has a strip-shaped drainage portion with a plurality of drainage holes extending at the upper end, so that the water used in the bathroom etc. It goes to the drainage side and drains smoothly from the drainage hole.

  Hereinafter, embodiments according to the present invention will be described in detail. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  As the tatami core material 11, a water-resistant synthetic resin material is suitable, and a relatively hard foamed resin material having a cushioning property to some extent may be used. For example, polyolefin resins such as closed cell foamed styrene resin, foamed urethane resin, and foamed polyethylene are preferred. Further, these foamed resins may be combined and used in combination. FIG. 3 is a partially enlarged perspective view of the tatami core 11 portion. On the upper surface of the tatami core material 11, a plurality of holes 11 a for loading tablets 15 such as fragrances, antibacterial agents, and deodorants are provided. Further, side groove members 14 having an L-shaped cross section for forming drainage grooves are disposed on both side surfaces of the tatami core material 11. Such a side groove member 14 is for improving drainage efficiency and may be provided as necessary.

  As the tatami surface 12, it is preferable to use a woven synthetic fiber material having water resistance. For example, when thick multifilaments are used as wefts and nylon yarns are used as warp yarns and woven into tatami mats to form a satin shape, they can be used as water-resistant tatami mats that are inferior to conventional tatami mats in appearance. In this example, it is cut in advance according to the shape of the tatami core material 11, and both end portions are set to be longer than the tatami core material 11 for fixing as described above.

  On the laying surface of the washing place 2, a base member 13 is disposed around the tatami core material 11 along the side surface. As shown in the partially enlarged perspective view of FIG. 4, the base member 13 is formed in an inverted T-shaped cross section, and a foot portion 13a having a predetermined width is provided on the bottom portion in a belt shape over the entire length. A wall 13b having a predetermined height is erected over the entire length at a substantially central portion of 13a. The wall portion 13b is formed with an engaging groove 13c with a central portion drilled over the entire length. The inner wall of the engagement groove 13c has a plurality of steps in the longitudinal direction and has a saw-shaped cross section.

In this example, it is arrange | positioned in the edge part along the outer surface of the bathtub 1 in the laying surface of the washing place 2. As shown in FIG. As in FIG. 4, the base member 13 ′ has a foot 13a ′ having a predetermined width formed over the entire length at the bottom, but the wall 13b ′ is erected over the entire length by moving toward the bathtub 1 side. The foot 13a ′ slightly protrudes from the bathtub 1 side. An engagement groove 13c 'is formed over the entire length of the central portion of the wall portion 13b', and a plurality of steps are formed on the inner wall as in the case shown in FIG. A strip-shaped drainage portion 13d ′ is extended over the entire length at the upper end of the wall portion 13b ′ so as to protrude toward the bathtub 1, and a plurality of drainage holes 13e ′ are formed in the drainage portion 13d ′. ing.

  The surface of the tatami core 11 supported by installing the peripheral edge portion on the foot of the base member 13 is covered with the tatami table 12, and the tatami table 12 is fixed by the cover members 16 and 16 '. As shown in the partially enlarged perspective view of FIG. 6, the cover member 16 is formed in a T-shaped cross section, and is engaged with the engagement portion over the entire length at the center of the lower surface of the tatami edge 16 a formed in a band shape over the entire length. 16b protrudes downward. The same material as that of the conventional tatami rim may be attached to the surface of the tatami rim 16a.

  A plurality of steps are formed in the longitudinal direction on both side walls of the engaging portion 16b, and the cross-sectional shape is a saw shape. The engaging portion 16b is set to have substantially the same length and thickness as the depth and width of the engaging groove 13c so that the engaging portion 16b can engage with the engaging groove 13c of the base member 13. The plurality of formed steps are also formed so as to mesh with the steps formed on the inner wall of the engagement groove 13c. Each step on the inner wall of the engagement groove 13c and the both side walls of the engagement portion 16b is formed in a taper shape so that the cross-sectional shape expands from bottom to top. It can be easily inserted when being inserted into, but cannot be easily pulled out when the engaging portion 16b is removed.

  You may make it attach the flexible strip | belt-shaped sheet | seat material which made the thickness of the front-end | tip gradually thin so that a level | step difference may not arise in the both-sides edge part of the tatami edge part 16a.

  FIG. 7 is a partially enlarged perspective view of the cover member 16 ′ that contacts the wall surface 3 at the edge portion of the tatami mat floor structure. The cover member 16 ′ includes a tatami rim 16 a ′ and an engaging portion 16 b ′ in the same manner as the cover member 16, but the tatami rim 16 a ′ is formed only on one side opposite to the wall 3. On the side 3, a covering portion 16 c ′ is formed in a strip shape over the entire length and is slightly curved upward. The covering portion 16c 'is made of a flexible material, and is formed so that the thickness gradually decreases toward the tip. For this reason, when the covering portion 16 c ′ comes into contact with the wall surface 3, the covering portion 16 c ′ is bent over the entire length, and the entire surface comes into close contact with the wall surface 3 reliably.

  8 shows a cross-sectional view taken along the line AA in FIG. 1, and FIG. 9 shows a cross-sectional view taken along the line BB in FIG. As shown in FIG. 8, both end portions of the tatami table 12 are inserted into the engagement grooves 13c of the base member 13 together with the engagement portions 16b of the cover member 16, and the steps of the engagement grooves 13c and the engagement portions 16b are stepped. It is clamped and fixed by meshing. When fixing the end portion of the tatami surface 12, the end portion may be inserted into the engagement groove 13c in advance and the engagement portion 16b may be inserted. When the engaging portion 16b is inserted, the end portion of the tatami table 12 is also drawn, so that the tatami table 12 can be fixed in a tensioned state.

  Further, the cover member 16 is attached by arranging the peripheral edge portion of the tatami core material 11 on the foot portion 13 a of the base member 13, whereby the tatami core material 11 is formed by the foot portion 13 a of the base member 13 and the tatami edge portion 16 a of the cover member 16. The peripheral edge of each of the two is clamped and fixed.

The drainage channel 17 is formed. Accordingly, the hot water flowing in the washing place 2 flows into the drainage channel 17 from the surface of the tatami mat 12 and is smoothly drained, and does not stay on the tatami mat 12. The hot water flowing into the drainage channel 17 flows toward the bathtub 1, flows along the wall portion 13 b ′ of the base member 13 ′ provided at the edge portion on the bathtub 1 side, and is guided to the drainage port 20.

  The base member 13 ′ provided at the edge portion on the bathtub 1 side is provided with a drainage portion 13 d ′, and a space is formed along the side surface of the bathtub 1 below the drainage portion 18. Yes. Therefore, the hot water overflowing from the bathtub 1 passes through the drain hole 13e 'drilled in the drain section 13d' and is quickly drained from the drain channel 18. Therefore, hot water overflowing from the bathtub 1 is prevented from flowing into the tatami mat floor structure 10 and staying there. Hot water that has flowed into the drainage channel 18 flows from the cutout portion 19 formed in the wall portion 13b 'of the base member 13' to the drainage port 20.

  In the case where drainage at the washing place 2 is performed more effectively, if the tatami surface 12 and the tatami core material 11 are provided with many small through holes in the vertical direction so that the hot water flows downward, the tatami core material 11 Since a gap is formed between the legs of the base member 13 and the laying surface, the water is quickly drained from the gap.

  In addition, since the covering portion 16c ′ of the cover member 16 ′ provided on the edge portion is in a state of being in close contact with the wall surface 3, the gap at the edge portion is surely covered. Become. Further, since the covering portion 16c ′ of the cover member 16 ′ is bent and is in close contact, the cover member 16 ′ does not shift to the wall surface 3 side, and even if a person walks on the tatami floor structure 10 It will be kept stable.

  FIG. 10 is a partially enlarged perspective view of the base member 23 (FIG. 10B) and the cover member 26 (FIG. 10A) according to another embodiment, and FIG. 11 shows the base member 23 and the cover member 26. It is a partially expanded sectional view of the tatami mat floor structure using the.

  In this example, the foot 23a of the base member 23 extends only on one side of the wall 23b, and the wall 23b is formed with an engagement groove 23c similar to the engagement groove 13c described above. Further, the tatami edge portion 26a of the cover member 26 extends only on one side of the engaging portion 26b, and the engaging portion 26b is formed in the same shape as the engaging portion 26b described above.
