Description

[Technical Field]

[0001] FIELD OF THE INVENTION Aspects of the present invention relate generally to bathroom floors. [Background technology]

[0002] It has been known that drainage of bathroom floors can be improved by providing multiple protrusions on the surface and allowing water to flow through grooves located between the protrusions and into a drain (see, for example, Patent Document 1). In such bathroom floors, drainage is improved by providing cutouts connecting the grooves and the drain. Meanwhile, in recent years, studies have been conducted to improve the design by making the sizes and shapes of the multiple protrusions on the surface of bathroom floors irregular. However, making the sizes and shapes of the multiple protrusions irregular makes it difficult to align the positions of the grooves and the cutouts, resulting in a problem of reduced drainage. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6953854 Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been made based on the recognition of such problems, and aims to provide a bathroom floor that combines design and drainage properties. [Means for solving the problem]

[0005] The first invention is a bathroom floor comprising: a floor body having an opening penetrating in the vertical direction, a plurality of convex portions protruding upward, and groove portions located between the plurality of convex portions and continuously connected; and a drainage pit provided in the opening and forming a drain outlet, wherein each of the plurality of convex portions differs from at least one of adjacent convex portions in at least one of their size in a planar view and their shape in a planar view, the opening has an edge portion extending along a first direction in a planar view, and a cutout portion provided in the edge portion that is recessed toward a second direction that intersects the first direction in a planar view, the groove portion extending along the second direction and having a plurality of first groove regions lined up along the edge portion, and the cutout portion is provided at a position where one of the plurality of first groove regions intersects with the edge portion.

[0006] According to this bathroom floor, each of the multiple convex portions differs from at least one of the adjacent convex portions in at least one of the size in plan view and the shape in plan view, thereby making the sizes and shapes of the multiple convex portions irregular. This improves design. Furthermore, the multiple first groove regions extending along the second direction are aligned along the edge of the opening, making it easy to align the positions of the groove portions (first groove regions) and the cutout portions. This improves drainage. Therefore, both design and drainage are achieved.

[0007] A second invention is a bathroom floor according to the first invention, wherein the plurality of first groove areas are arranged at equal intervals along the edge portion.

[0008] With this bathroom floor, the multiple first groove areas are arranged at equal intervals along the edge of the opening, making it easier to align the positions of the grooves (first groove areas) with the positions of the notches, further improving drainage.

[0009] The third invention is a bathroom floor according to the first invention, wherein the groove portion is provided on the edge portion, extends along the first direction, and further has second groove regions connected to each of the plurality of first groove regions, and the cutout portion is provided at a position where one of the plurality of first groove regions intersects with the second groove region.

[0010] According to this bathroom floor, the grooves are provided on the edge and further include second groove regions that connect to each of the multiple first groove regions. This allows water flowing through the multiple first groove regions to be collected in the second groove region that passes near the opening (drain outlet). This further improves drainage. Furthermore, a cutout is provided at the intersection of one of the multiple first groove regions and the second groove region, allowing water flowing through one of the first groove regions and water flowing through the second groove region to merge and be efficiently drained from the cutout. This prevents water from accumulating on the floor body and allows water to be guided to the drain outlet.

[0011] A fourth invention is a bathroom floor according to the third invention, wherein the second groove area extends continuously from one end to the other end of the floor body in the first direction when viewed in a plan view.

[0012] According to this bathroom floor, the second groove area extends continuously from one end to the other end of the floor body in the first direction in a plan view, which prevents water from accumulating in the second groove area, thereby further improving drainage performance.

[0013] The fifth invention is a bathroom floor in which, in the first invention, the floor body is aligned with the bathtub in the second direction, and the edge portion and the cutout portion are located at the end of the opening opposite the bathtub in the second direction.

[0014] With this bathroom floor, multiple first groove areas are lined up along the edge located at the end of the opening opposite the bathtub, and a cutout is provided at the position where one of the multiple first groove areas intersects with the edge, further improving drainage performance.

[0015] A sixth invention is a bathroom floor according to any one of the first to fifth inventions, wherein the groove portion further has a third groove region extending along the first direction, and the rattle of the third groove region in the second direction is greater than the rattle of the second groove region in the second direction.

[0016] According to this bathroom floor, the groove portion further includes a third groove region, and the wobble of the third groove region in the second direction is greater than the wobble of the second groove region in the second direction, so that the second groove region that is easy to see as a straight line and the third groove region that is difficult to see as a straight line can be mixed together, which further improves the design. [Effects of the Invention]

[0017] According to an aspect of the present invention, a bathroom floor that combines design and drainage properties can be provided. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, embodiments will be described with reference to the drawings. In the drawings, like components are designated by like reference numerals, and detailed descriptions thereof will be omitted where appropriate.

[0020] (First embodiment) FIG. 1 is a perspective view showing a bathroom unit equipped with a bathroom floor according to the first embodiment. As shown in FIG. 1, the bathroom unit 500 according to the first embodiment includes a bathroom floor 100, a bathtub 200, and wall panels 300a to 300f.

[0021] Bathtub 200 is installed on an installation surface (e.g., a building floor) S via support legs 210. Support legs 210 are provided near the four corners on the back surface of the bottom of bathtub 200. A bolt portion is provided on the tip side (lower end side) of support leg 210, and the height of support leg 210 can be adjusted by rotating this bolt portion.

[0022] The bathroom floor 100 is installed on an installation surface S via support legs 110. The bathroom floor 100 is installed next to the bathtub 200. The support legs 110 are provided on the underside of the bottom of the bathroom floor 100. A bolt portion is provided on the tip side (lower end side) of the support legs 110, and the height of the support legs 110 can be adjusted by rotating the bolt portion.

[0023] The surface 100a of the bathroom floor 100 is waterproof so that water does not leak outside the bathroom. Note that in this specification, the term "water" includes not only cold water but also heated water.

[0024] A drain pipe 220 is provided on the back (lower side) of the bathroom floor 100, near the boundary with the bathtub 200. A drain outlet 100h that communicates with the drain pipe 220 is formed in the bathroom floor 100, near the boundary with the bathtub 200. The drain outlet 100h may be covered with a removable lid. The portion where the drain outlet 100h is provided is recessed downward, and the surface 100a of the bathroom floor 100 has a drain slope that slopes downward toward the drain outlet 100h. In addition, a drain outlet (not shown) provided at the bottom of the bathtub 200 is also connected to the drain pipe 220.

[0025] As shown by the two-dot chain line in Figure 1, wall panels 300a-300c are installed on the rim of bathtub 200. Wall panels 300d-300f are installed on the peripheral edge of bathroom floor 100. A bathroom door is attached to any of wall panels 300d, 300e, and 300f, for example, via a door mounting frame (not shown).

[0026] A bath apron 230 is provided at the boundary between the bathtub 200 and the bathroom floor 100, covering the side of the bathtub 200 facing the bathroom floor 100. Depending on the structure of the bathtub 200, it may not be necessary to provide a bath apron 230.

[0027] A small panel 240 is provided between one longitudinal end of the bus apron 230 and the wall panel 300d. A small panel 250 is provided between the other longitudinal end of the bus apron 230 and the wall panel 300f. The small panels 240 and 250 are provided as needed and can be omitted.

[0028] In this specification, the direction from wall panel 300e toward wall panel 300b is referred to as the "front," the direction from wall panel 300b toward wall panel 300e is referred to as the "rear," the direction from wall panel 300d toward wall panel 300f is referred to as the "left side," and the direction from wall panel 300f toward wall panel 300d is referred to as the "right side." The bathtub 200 is located in front of the bathroom floor 100.

[0029] The bathroom floor 100 according to the first embodiment will be described below. FIG. 2 is a plan view showing the bathroom floor according to the first embodiment. FIG. 3 is a plan view showing a portion of the bathroom floor according to the first embodiment. FIG. 4 is a cross-sectional view showing a portion of the bathroom floor according to the first embodiment. FIG. 3 is an enlarged view of the region R1 shown in FIG. FIG. 4 is a cross-sectional view taken along line IV-IV shown in FIG. As shown in FIGS. 2 to 4, the bathroom floor 100 according to the first embodiment has a floor body 10 and a drainage pit 20.

[0030] An opening 15 is provided in the floor body 10. The opening 15 penetrates the floor body 10 in the vertical direction. A drainage pit 20 is provided in the opening 15. A through-hole 25 is provided in the drainage pit 20. The through-hole 25 penetrates the drainage pit 20 in the vertical direction. The through-hole 25 is connected to the drainage piping 220 described above. Water that has flowed over the floor body 10 passes through the through-hole 25 of the drainage pit 20 provided in the opening 15 and is discharged into the drainage piping 220. In this way, the drainage pit 20 forms a drain outlet 100h of the bathroom floor 100. The drainage pit 20 is connected to the opening 15, for example, from below.

[0031] The opening 15 has an edge 15a and a notch 15b. The edge 15a extends along a first direction D1 in a plan view. The notch 15b is provided in the edge 15a. The notch 15b is recessed toward a second direction D2 in a plan view. The second direction D2 intersects with the first direction D1 in a plan view.

[0032] In the bathroom floor 100, the first direction D1 is a direction along the left-right direction. The first direction D1 may be any direction along a plane perpendicular to the up-down direction, and may be, for example, a direction along the front-to-back direction, or a direction intersecting the front-to-back direction and the left-to-right direction. In the bathroom floor 100, the second direction D2 is a direction perpendicular to the first direction D1. The second direction D2 may be, for example, a direction intersecting the first direction D1 diagonally. In the bathroom floor 100, the second direction D2 is a direction along the front-to-back direction. The second direction D2 may be any direction along a plane perpendicular to the up-to-down direction and intersecting the first direction D1, and may be, for example, a direction along the left-to-right direction, or a direction intersecting the front-to-back direction and the left-to-right direction.

[0033] The drainage pit 20 has a concave shape that is recessed downward. More specifically, the drainage pit 20 has a bottom surface portion 21 and an upright surface portion 22. The bottom surface portion 21 is located at the bottom of the drainage pit 20. The through-hole 25 penetrates the bottom surface portion 21 in the vertical direction. The upright surface portion 22 extends upward from the peripheral edge of the bottom surface portion 21. A groove 22a is provided in a part of the upright surface portion 22, which is recessed toward the opposite side from the through-hole 25 in a plan view. The groove 22a extends continuously from the upper end to the lower end of the upright surface portion 22. The groove 22a is provided as needed and can be omitted.

[0034] The floor body 10 has a plurality of protrusions 11 and grooves 12. The plurality of protrusions 11 and grooves 12 are provided on the upper surface of the floor body 10.

[0035] The plurality of protrusions 11 protrude upward. Each of the plurality of protrusions 11 differs from at least one of the adjacent protrusions 11 in at least one of the size in a plan view and the shape in a plan view. Each of the plurality of protrusions 11 may differ from at least one of the adjacent protrusions 11 in either the size in a plan view or the shape in a plan view, or may differ from at least one of the adjacent protrusions 11 in both the size in a plan view and the shape in a plan view.

[0036] Two adjacent ones of the plurality of protrusions 11 are different in, for example, at least one of the size in a plan view and the shape in a plan view. Two adjacent ones of the plurality of protrusions 11 are not congruent in a plan view, for example. Two adjacent ones of the plurality of protrusions 11 may be similar in a plan view, for example. Two non-adjacent ones of the plurality of protrusions 11 may be congruent in a plan view, for example. The size of the protrusions 11 in a plan view may be, for example, the area of the protrusions 11 in a plan view, the maximum length of the protrusions 11 in a plan view, or the length of the entire circumference of the protrusions 11 in a plan view.

[0037] In the bathroom floor 100, the floor body 10 has a fabric-like uneven shape that combines protrusions 11 that extend along the first direction D1 and protrusions 11 that extend along the second direction D2. This uneven shape can improve the design compared to an uneven shape that only has protrusions that are the same size and shape in a plan view (i.e., an uneven shape where the size and shape of the protrusions are regular).

[0038] The grooves 12 are located between the plurality of protrusions 11. The grooves 12 are continuously connected. For example, the grooves 12 are continuously connected to the openings 15 in a meandering manner. The grooves 12 have, for example, a plurality of first groove regions 12a and second groove regions 12b.

[0039] Each of the multiple first groove regions 12a extends along the second direction D2. The multiple first groove regions 12a are aligned along the edge 15a. The multiple first groove regions 12a are aligned, for example, at equal intervals along the edge 15a. In this specification, the multiple first groove regions 12a are considered to be "equally spaced" if the spacing between them in the first direction D1 is within ±10% of the average value. Here, "equally spaced" means that the grooves are formed at equal intervals. For example, if the shape has grooves arranged at equal intervals, other grooves may be formed between the grooves. In other words, other grooves (groove regions) may be provided between the multiple first groove regions 12a aligned at equal intervals.

[0040] The multiple first groove regions 12a are provided at positions that overlap with the edge portion 15a (opening 15) in the second direction D2. In the bathroom floor 100, the multiple first groove regions 12a are provided not only at positions that overlap with the edge portion 15a (opening 15) in the second direction D2, but also at positions that do not overlap with the edge portion 15a (opening 15) in the second direction D2.

[0041] The second groove region 12b is provided on the edge portion 15a. The second groove region 12b extends along the first direction D1. The second groove region 12b is connected to each of the multiple first groove regions 12a. This allows water that has flowed through each of the multiple first groove regions 12a to join together in the second groove region 12b.

[0042] The second groove region 12b is provided, for example, at a position overlapping with the edge portion 15a (opening 15) in the second direction D2. As shown in FIG. 2, in the bathroom floor 100, the second groove region 12b extends continuously from one end 10x to the other end 10y in the first direction D1 of the floor body 10 in a plan view. In other words, in the bathroom floor 100, the second groove region 12b is provided not only at a position overlapping with the edge portion 15a (opening 15) in the second direction D2, but also at a position not overlapping with the edge portion 15a (opening 15) in the second direction D2. The second groove region 12b is provided as needed and can be omitted.

[0043] In the bathroom floor 100, the cutout portion 15b is provided at a position where one of the multiple first groove regions 12a intersects with the edge portion 15a. In other words, the cutout portion 15b overlaps with one of the multiple first groove regions 12a in the second direction D2. This allows water that flows through the multiple first groove regions 12a to pass through the cutout portion 15b and be discharged into the drainage pit 20 (drain outlet 100h) provided in the opening 15.

[0044] In addition, in the bathroom floor 100, a second groove area 12b is provided in the edge portion 15a, and the cutout portion 15b is provided at a position where one of the multiple first groove areas 12a intersects with the second groove area 12b. As a result, water that has flowed through the multiple first groove areas 12a and the second groove area 12b passes through the cutout portion 15b and is discharged into the drainage pit 20 (drain outlet 100h) provided in the opening 15.

[0045] In addition, two cutout portions 15b are provided in the bathroom floor 100, and both of the two cutout portions 15b are provided at a position where one of the multiple first groove regions 12a intersects with the edge portion 15a. In addition, both of the two cutout portions 15b are provided at a position where one of the multiple first groove regions 12a intersects with the second groove region 12b.

[0046] When a plurality of cutout portions 15b are provided, some of the cutout portions 15b may be provided at positions where the plurality of first groove regions 12a do not intersect with the edge portion 15a (i.e., positions that do not overlap with the plurality of first groove regions 12a in the second direction D2). Also, when a plurality of cutout portions 15b are provided, some of the cutout portions 15b may be provided at positions where the plurality of first groove regions 12a do not intersect with the second groove regions 12b (i.e., positions that do not overlap with positions where the plurality of first groove regions 12a and second groove regions 12b intersect with each other in the second direction D2).

[0047] In addition, in the bathroom floor 100, a groove 22a is provided in the vertical portion 22 of the drainage pit 20, and the cutout portion 15b is provided at a position that overlaps with the groove 22a in the second direction D2 in a plan view. The cutout portion 15b may also be provided at a position that does not overlap with the groove 22a in the second direction D2 in a plan view.

[0048] In the bathroom floor 100, the floor body 10 is aligned with the bathtub 200 in the second direction D2. In the bathroom floor 100, the edge portion 15a and the cutout portion 15b are located at the end of the opening 15 opposite the bathtub 200 in the second direction D2. In other words, the multiple first groove regions 12a and second groove regions 12b are located on the opposite side of the opening 15 from the bathtub 200 in the second direction D2. Here, we have described the case where the groove portion 12, the edge portion 15a, and the cutout portion 15b are located at the end of the opening 15 opposite the bathtub 200 in the second direction D2, but this is not limited to this, and the groove portion 12, the edge portion 15a, and the cutout portion 15b may also be located at the end of the opening 15 on the bathtub 200 side in the second direction D2.

[0049] As shown in Fig. 4, the floor body 10 has, for example, a base material 10a and a skin material 10b. The base material 10a is located at the bottom of the floor body 10. The skin material 10b is located on top of the base material 10a. The skin material 10b forms the upper surface of the floor body 10. A plurality of protrusions 11, grooves 12, and cutouts 15b are each provided in the skin material 10b. An opening 15 passes through the base material 10a and the skin material 10b in the vertical direction.

[0050] The base material 10a is made of, for example, expanded polypropylene (EPP), fiber reinforced plastic (FRP), etc. The cover material 10b is made of, for example, polyvinyl chloride (PVC), olefin, soft FRP, etc. The floor body 10 is produced, for example, by attaching the cover material 10b onto the base material 10a.

[0051] Below, the effects of the bathroom floor 100 according to the first embodiment will be explained. In recent years, in order to improve the design, it has been considered to make the size and shape of the multiple convex portions on the surface of the bathroom floor irregular. However, when the size and shape of the multiple convex portions are made irregular, it becomes difficult to align the positions of the grooves and the cutouts, which causes a problem of reduced drainage.

[0052] In contrast, in the bathroom floor 100, each of the multiple convex portions 11 differs from at least one of the adjacent convex portions 11 in at least one of the size in a planar view and the shape in a planar view, thereby making the sizes and shapes of the multiple convex portions 11 irregular. This improves design. Furthermore, the multiple first groove regions 12a extending along the second direction D2 are aligned along the edge portion 15a of the opening 15, making it easy to align the position of the groove portion 12 (first groove region 12a) with the position of the cutout portion 15b. This improves drainage. Therefore, both design and drainage can be achieved.

[0053] Furthermore, in the bathroom floor 100, the multiple first groove regions 12a are arranged at equal intervals along the edge 15a of the opening 15, making it easier to align the positions of the grooves 12 (first groove regions 12a) with the positions of the cutouts 15b. This further improves drainage.

[0054] Furthermore, in the bathroom floor 100, the groove portion 12 is provided on the edge portion 15a and further includes second groove regions 12b that are connected to each of the multiple first groove regions 12a. This allows water flowing through the multiple first groove regions 12a to be collected in the second groove region 12b that passes near the opening 15 (drain outlet 100h). This further improves drainage. Furthermore, the cutout portion 15b is provided at the position where one of the multiple first groove regions 12a intersects with the second groove region 12b, allowing water flowing through one of the first groove regions 12a and water flowing through the second groove region 12b to merge and be efficiently drained from the cutout portion 15b. This prevents water from accumulating on the floor body 10 and allows water to be guided to the drain outlet 100h.

[0055] Furthermore, in the bathroom floor 100, the second groove region 12b extends continuously from one end 10x to the other end 10y in the first direction D1 of the floor body 10 in a plan view, thereby preventing water from accumulating in the second groove region 12b. This further improves drainage. For example, by manufacturing the floor body 10 using a covering material 10b having a second groove region 12b that extends continuously in the first direction D1, it is possible to manufacture a floor body 10 having a second groove region 12b that extends continuously from one end to the other end in the first direction D1 of the floor body 10 in a plan view, regardless of where the covering material 10b is cut.

[0056] In addition, in the bathroom floor 100, at the edge portion 15a located at the end opposite the bathtub 200 of the opening 15, multiple first groove areas 12a are lined up along the edge portion 15a, and a cutout portion 15b is provided at a position where one of the multiple first groove areas 12a intersects with the edge portion 15a, thereby further improving drainage performance.

[0057] (Second embodiment) FIG. 5 is a plan view showing a bathroom floor according to the second embodiment. FIG. 6 is a plan view showing a portion of the bathroom floor according to the second embodiment. FIG. 7 is a cross-sectional view showing a portion of the bathroom floor according to the second embodiment. FIG. 6 is an enlarged view of the region R2 shown in FIG. FIG. 7 is a cross-sectional view taken along line VII-VII shown in FIG. 8(a) and 8(b) are explanatory diagrams of the wobble in the groove region. As shown in Figures 5 to 7, the bathroom floor 100A of the second embodiment is essentially the same as the bathroom floor 100 of the first embodiment, except that the shapes of the multiple convex portions 11 on the floor main body 10 are different.

[0058] In the bathroom floor 100A, the floor body 10 has a stone-like uneven shape made up of a combination of protrusions 11 that have slightly different shapes when viewed from above. This uneven shape improves the design compared to an uneven shape that only has protrusions that are the same size and shape when viewed from above (i.e., an uneven shape where the size and shape of the protrusions are regular).

[0059] In the bathroom floor 100A, the groove portion 12 also has a plurality of first groove regions 12a and a second groove region 12b. The plurality of first groove regions 12a are aligned along the edge portion 15a. The cutout portion 15b is provided at a position where one of the plurality of first groove regions 12a intersects with the edge portion 15a in the second direction D2. The cutout portion 15b is also provided at a position where one of the plurality of first groove regions 12a intersects with the second groove region 12b.

[0060] In the bathroom floor 100A, the groove portion 12 further has a third groove region 12c. The third groove region 12c extends along the first direction D1. The rattle of the third groove region 12c in the second direction D2 is greater than the rattle of the second groove region 12b in the second direction D2. A groove region with greater rattle appears less linear than a groove region with less rattle. In other words, the third groove region 12c appears less linear than the second groove region 12b.

[0061] As shown in FIGS. 8(a) and 8(b), the wobble in the second direction D2 of a groove region (such as the second groove region 12b or the third groove region 12c) extending along the first direction D1 is determined, for example, for a groove region 12x that is sandwiched between convex portions 11 in the second direction D2 among the groove regions extending along the first direction D1. When an imaginary line IL is drawn connecting one end E1 and the other end E2 of the groove region 12x in the first direction D1, the wobble is expressed as the ratio of convex portions 11 that overlap the imaginary line IL among the convex portions 11 adjacent to the imaginary line IL. For example, in the groove region of FIG. 8(a), of the 20 convex portions 11 adjacent to the imaginary line IL, two convex portions 11 overlap the imaginary line IL. Therefore, the wobble of the groove region of FIG. 8(a) is 2 / 20=0.1. In the groove region of Figure 8(b), of the 20 protrusions 11 adjacent to the imaginary line IL, five protrusions 11 overlap the imaginary line IL. Therefore, the wobble in the groove region of Figure 8(b) is 5 / 20 = 0.25. The wobble in the groove region of Figure 8(b) is larger than the wobble in the groove region of Figure 8(a).

[0062] The groove portion 12 may have one or more third groove regions 12c. The third groove regions 12c are provided as needed and can be omitted. The groove portion 12 may further have a groove region having a wobble in the second direction D2 that is similar to that of the second groove region 12b.

[0063] Below, the effects and advantages of the bathroom floor 100A of the second embodiment will be explained. The bathroom floor 100A of the second embodiment also provides the same effects and advantages as the bathroom floor 100 of the first embodiment described above. Explanations of the effects and advantages similar to those of the bathroom floor 100 of the first embodiment described above will be omitted.
