  It is good also as a structure which makes the surface of the base material which comprises the said sheet | seat hydrophilic, and makes the convex part of this base material water-repellent.

  It is good also as a structure which printed on the surface of the base material which comprises the said sheet | seat with the ink which a volume expand | swells with an ultraviolet-ray, and was expanded by irradiating this ink with an ultraviolet-ray, and formed the convex part.

  According to the floor sheet for a washing place according to the present invention having the above-described structure, when the washing place is reformed, the floor sheet for the washing place is formed on the floor sheet for the washing place by forming an uneven pattern for improving water drainage as described above. In addition to making the design different from the original color pattern, it is possible to easily and reliably improve the water washing performance of the washing place.

  The best mode for carrying out a floor sheet for a washing place according to the present invention will be described with reference to the drawings based on the embodiments.

  Fig.1 (a) is a top view of the floor of the existing washroom of a bathroom. FIG.1 (b) is AA sectional drawing of the vicinity of the drain port 3 mentioned later of Fig.1 (a). In FIG. 1 (a), a drainage port 3 is formed in an existing washing place 1 adjacent to, for example, the central portion of the side edge 2 'of the bathtub 2. The floor 4 of the existing washing place 1 has a drainage gradient that gradually decreases toward the drainage port 3 as shown by the arrow in FIG. 1A and as shown in FIG.

  As shown in FIG. 1 (b), the drainage port 3 and the floor 4 of the existing washroom 1 are formed so that the lowest surface 5 of the floor 4 of the existing washroom 1 and the side wall surface 6 of the drainage port 3 are coupled. It is configured.

  FIG.1 (c) is a top view which shows the state which affixed the floor sheet 7 of the washing place which concerns on this invention on the surface of the floor 4 of the existing washing place 1. FIG. The floor sheet 7 has an uneven pattern 8 formed on the surface for improving water repellency. The size (vertical and horizontal dimensions) of the floor sheet 7 is as shown in FIG. 1 (c). It is assumed that it is slightly smaller than the floor 4.

  The floor sheet 7 has a space s (the width dimension is also assumed to be s) along the side edge 2 'of the bathtub 2 on the surface of the floor 4, and is adhered to almost the entire surface, so that FIG. As in the existing washing place 1 shown in a), a drainage gradient is provided toward the drainage port 3.

  FIG. 1D is a cross-sectional view in the vicinity of the drain port 3 in FIG. 1C (the cross-section indicating line is the same as AA in FIG. 1B, and is omitted). The floor sheet 7 of the washing place of the present invention affixed to the surface of the floor 4 has a cut piece 13 (details will be described later) along the side wall surface 6 of the drainage port 3 from the lowest surface 5 of the floor 4. It is hanging down and pasted.

  FIG. 2A shows a plan view of the floor sheet 7 before construction applied to the surface of the floor 4. The floor sheet 7 is preferably made of a resin material and can be bent so that the floor sheet 7 can be bent and attached along the side wall surface 6 of the drain port 3. Further, the floor sheet 7 is preferably made of a slightly cushioning material that is kind to the feet of the bather, and the surface is appropriately provided with a color pattern, a pattern, or the like by inkjet printing or the like.

  Although not shown, an adhesive is applied in advance to the back surface of the floor sheet 7, and a protective paper that can be peeled off is applied to the outside. Alternatively, the adhesive may be applied to the back surface of the floor sheet 7 when the floor sheet 7 is attached to the surface of the floor 4 without previously applying the adhesive to the back surface of the floor sheet 7.

  As described above, the floor sheet 7 has a concavo-convex pattern 8 for improving water drainage on the surface thereof. Although various patterns can be considered as the concavo-convex pattern 8, in the first embodiment, a plurality of rectangular convex portions 9 are arranged in a matrix, and the concave portions 10 between the convex portions 9 and the adjacent convex portions 9 are arranged. (A concave portion when viewed from the convex portion 9) becomes a narrow groove-like flow path 11, through which the water in the washing place flows down.

  The plurality of rectangular protrusions 9 may be integrally formed on the surface of the floor sheet 7 by a method such as embossing, or may be formed on the surface of the base material 7 'of the floor sheet 7 in an embodiment described later. It may be formed by printing as shown, or by attaching a rectangular piece with an adhesive or the like.

  Since the effect of improving the water drainage property by such an uneven pattern 8 has already been described in Japanese Patent Application Laid-Open No. 2003-206558 related to the present applicant, detailed description is omitted, but the uneven pattern 8 The flowing water flowing through the narrow groove-shaped flow path 11 that is the concave portion 10 of the liquid attracts the water droplets existing on the surface of the convex portion 9 into the flow channel so as not to leave residual water in the convex portion. It is.

  When the floor sheet 7 is affixed to the surface of the floor 4, as shown in FIG. 2 (b), the floor sheet 7 is provided with cuts 12 corresponding to the drain ports 3, and the cut pieces 13 are formed. It is formed. As described above, the cut piece 13 may be formed by inserting the cut 12 when renovation is performed. Alternatively, the cut piece 13 may be formed in advance by forming the cut 12 when the sheet is formed.

  In other words, since the size of the bathroom washing area, the position of the drainage port 3 and the dimensions thereof are known in advance for the unit bath or the like, the floor sheet 7 is formed in advance when the floor sheet 7 is formed corresponding to the shape of the unit bath. The notch 12 may be formed in. In the case of a hard sheet that is not easy to cut when performing renovation, it is desirable that the sheet is previously cut.

  Further, when the floor sheet 7 is made of a hard material, if the planned cut portion and the bent portion where the cut 12 should be made are formed thin at the time of manufacture, the cut can be easily made during the renovation work. 12 can be easily inserted, and can be easily folded along the folding portion 14.

When the horizontal width of the drain port 3 is w ₁ (see FIG. 2D), the vertical width of the drain port 3 is w ₂ , and the depth of the drain port 3 is d (see FIG. 1D), a cut piece The size of 13, that is, the width w _{1 ′} of the cut piece 13 (also the interval of the cut 12) and the depth t of the cut piece 13 (the length of the cut 12, see FIG. 2B). 13 is bent so as to fit the width w ₁ of the side wall surface 6 of the drain port 3, and the cut piece 13 is attached to the side wall surface 6 of the drain port 3.

That is, the lateral width w _{1 ′} (see FIG. 2B) of the cut piece 13 is formed to be slightly smaller than the lateral width w ₁ of the drain port 3 more precisely, corresponding to the lateral width w ₁ of the drain port 3. . The depth t of the cut piece 13 is formed with the following dimensions.
(Depth t of cut piece 13) = (vertical width w ₂ of drain port 3) − (space s), and (depth t of cut piece 13) <(depth of drain port 3 d)

  When affixing the floor sheet 7 to the surface of the floor 4, after making a notch 12, the floor sheet 7 is placed on the surface of the floor 4 of the existing washing place 1 as shown in FIG. The sheet 7 is bonded to the back surface with an adhesive applied. Preferably, a caulking agent is coated between the floor 4 and the floor 4 for waterproofing.

  After the floor sheet 7 is affixed to the surface of the floor 4, as shown in FIGS. 1 (d) and 2 (d), the cut piece 13 is bent at the bent portion 14, and the side wall surface of the drainage port 3. 6 is pasted.

  In the configuration in which the floor sheet 7 is only attached to the surface of the floor 4 of the washing place, the water flowing through the flow path 11 formed by the uneven pattern 8 of the floor sheet 7 is the floor facing the drain port 3. There is a risk of stopping at the position of the lowest 5 of the sheet 7 for use.

  However, since the edge of the floor sheet in the washing area covers the drain of the washing area, and the uneven pattern reaches the side wall surface of the drain, the water flowing on the uneven pattern is not in the floor sheet of the washing area. The flow does not stop when it reaches the existing washroom floor from the edge. That is, the floor sheet 7 of the washing place according to the first embodiment is formed with a cut piece 13 corresponding to the drainage port 3 to form a cut piece 13, and this cut piece 13 is formed from the bottom 5 surface of the wash floor 4. Since it is configured to be attached so as to hang along the side wall surface 6 of the drain port 3, the water flowing through the flow path 11 formed by the uneven pattern 8 is further formed into the unevenness formed in the cut piece 13. It flows downward through the flow path 11 formed by the pattern 8 or without the flow path 11. This prevents water from staying at the lowest 5 position of the floor sheet 7.

  Example 2 of the floor sheet for a washing place according to the present invention has a configuration in which an uneven pattern 8 is formed on the surface thereof and a notch 12 is provided in the same manner as the floor sheet 7 for the washing place of Example 1. The structure is the same including Accordingly, FIGS. 1 and 2 are used for the drawings of the second embodiment, and the same reference numerals are used.

  A feature of the floor sheet 7 for the washing place of the second embodiment is a configuration in which at least the base material is formed of a foamable resin. Specifically, as an example, the concave-convex pattern 8 is formed on the surface of the base material formed of a foamable resin, and the base material itself becomes the floor sheet 7. As another example, there is a configuration in which the base material is formed of a foamable resin, and a hard resin layer formed of unevenness is laminated on the surface thereof. Or, conversely, there is a configuration in which the base material is formed of a hard resin layer and a foamable resin layer having irregularities formed on the surface thereof is laminated.

  Examples of the foamable resin used in this embodiment include those obtained by adding a foaming agent based on polyvinyl chloride resin, and those obtained by using ABS, polypropylene, polyurethane, polyethylene and the like as a base.

  In addition, a color pattern or the like is printed on the surface provided with the concave / convex pattern 8 by ink jetting. However, since the ink jet printing is performed, the concave / convex pattern 8 can be printed. The floor sheet 7 of the washing place of Example 2 prints a color pattern after molding, so that it is not necessary to knead the colorant at the material stage, and there is a degree of freedom in design, and various design color patterns can be imparted. it can.

  Since the floor sheet 7 of the washing place of Example 2 is formed of a foamable resin, the heat insulating property and the cushioning property are improved. For this reason, when the floor sheet 7 of the washing place of Example 2 is used, it is possible to prevent heat from escaping from the floor of the bathroom, to prevent a decrease in room temperature, and to provide cushioning, so that the bather The floor will be kind to your feet.

  In Example 3 of the floor sheet 7 for the washing place according to the present invention, similarly to the floor sheet 7 for the washing place of Example 1, an uneven pattern 8 is formed on the surface, and the notch 12 is given. The structure is the same including the configuration. Accordingly, FIGS. 1 and 2 are used for the drawings of the third embodiment, and the same reference numerals are used. The feature of the floor sheet 7 of the washing place of the third embodiment is a configuration in which the color pattern printed on the back surface from the front surface side is seen through.

  The floor sheet 7 of the washing place of Example 3 is formed of a transparent, translucent or transparent resin such as a resin containing vinyl chloride, and the uneven pattern 8 is formed on the surface by a mold for forming the uneven pattern 8. Is formed. The back surface of the floor sheet 7 is printed with a color pattern by an ink jet printer. The floor sheet 7 can be seen through the color pattern printed on the back surface from the front surface.

  In Example 3, since it is the structure which gave the color pattern to the back surface of the floor sheet 7 which can be seen through, if it has a depth and a three-dimensional feeling, and the floor sheet 7 is made translucent, it is synergistic and interesting. Designability arises. In addition, since the color pattern is printed on the back side, even if the surface of the floor sheet 7 is scratched, the color pattern print does not peel off, and the adhesive with the floor surface of the bathroom washroom can be printed with color pattern printing. It is possible to hide.

  FIG. 3 is a view for explaining Example 4 of a floor sheet for a washing place according to the present invention. As shown in FIG. 3A, the floor sheet 15 of the washing place in Example 4 is structurally implemented including the configuration in which the concave and convex pattern 8 is formed on the surface and the notch 12 is provided.
