On the other hand, the top plate member 2 can be formed of, for example, a resin material such as a foam material. Further, the apron member 3 can be formed of a resin material. However, in FIG. 1, the figure which removed the apron member 3 is shown. Hereinafter, these will be described in detail.

<1-1. Bathtub body>
FIG. 2 is a perspective view of the bathtub main body, and FIG. 3 is a cross-sectional view taken along the line AA of FIG. As shown in FIG. 2, the bathtub main body 1 includes a rectangular bottom wall 11 and a rectangular cylindrical side wall 12 rising from the periphery of the bottom wall 11. Is formed. More specifically, the bottom wall portion 11 is formed in a rectangular shape having a pair of long sides and a pair of short sides, among which one long side and the pair of short sides are generally bathroom It is comprised along the wall surface 5, and it is comprised so that another long side may turn to a washroom. Correspondingly, the side wall portion 12 is a pair of long wall portions (first wall surface portions) 121 and 122 rising from the long side of the bottom wall portion 11 and a pair of short wall portions (second wall surface portion) rising from the short side It is comprised by combining 123 and 124. Here, of the long wall portions 121 and 122 of the side wall portion 12, one facing the washing place is referred to as a first long wall portion 121, and the opposite side is referred to as a second long wall portion 122. Therefore, among the side wall portions, both the short wall portions 123 and 124 and the second long wall portion 122 are arranged to face the wall surface 5 of the washing place.

  In the side wall portion 12, a ridge portion 18 which extends in the vertical direction and protrudes toward the space portion side of the bathtub main body 1 is formed at the connection portion between the long wall portions 121 and 122 and the short wall portions 123 and 124. The protruding portion 18 forms a smooth surface that protrudes in an arc shape between the long wall portions 121 and 122 and the short wall portions 123 and 124. Furthermore, a flange portion 13 extending horizontally outward is formed at the upper end edge of the side wall portion 12, and an edge portion 14 extending downward is formed at the outer peripheral edge of the flange portion 13. Therefore, the flange portion 13 and the edge portion 14 are formed in a frame shape having a rectangular shape in a plan view so as to correspond to the side wall portion 12.

  As shown in FIG. 2, the connecting portion between the flange portion 13 and the side wall portion 12 is formed in a smooth arc shape. Further, circular mounting holes 15 (see FIG. 10) are formed in the flange portion 13 at a plurality of places, and the mounting holes 15 are used for fixing with the top plate member 2 described later. Three sides of the edge portion 14 face the wall surface 5 of the bathroom together with the side wall portion 12, but a gap is formed between the wall portion 5 and the wall portion 5. This point will be described later.

<1-2. Top plate member>
Next, the top plate member will be described with reference to FIGS. 4 to 7. 4 is a perspective view of the top plate member, FIG. 5 is a cross-sectional view taken along the line B-B in FIG. 1, FIG. 6 is a cross-sectional view taken along the line C-C in FIG. 1, and FIG. 7 is a cross-sectional view taken along the line D-D in FIG. .

  As shown in FIG. 4, the top plate member 2 is a member disposed on the flange portion 13 of the bathtub body 1, and is formed in a frame shape having a rectangular shape in a plan view. More specifically, the pair of long sides (first cover portions) 21 and 22 corresponding to the long wall portions 121 and 122 of the bathtub body 1, and the pair of short sides (second It is comprised by combining cover part 23 and 24 and. The long sides 21 and 22 and the short sides 23 and 24 are each formed in a rectangular shape, and can be formed, for example, by extrusion. The short sides 23 and 24 are fixed so as to connect the inner wall surfaces facing each other at both ends of the long sides 21 and 22. Hereinafter, among the two long sides 21 and 22, the long side facing the washing will be referred to as a first long side 21 and the opposite side will be referred to as a second long side 22.

<1-2-1. Long side>
Next, the first long side portion 21 will be described. As shown in FIG. 5, the first long side portion 21 has an upper surface 211, an inner wall surface 212 facing the inside of the bathtub, an outer wall surface 213 facing the outside of the bathtub, a lower surface 214, and a pair of side wall surfaces 215 at both ends in the longitudinal direction. And is formed in a rectangular parallelepiped shape as a whole.

  In particular, the first long side portion 21 largely protrudes from the flange portion 13 to the washing side, and the lower surface 214 of the first long side portion 21 has a projecting surface 2141 extending horizontally from the outside to the inside, and a flange A contact surface 2142 in contact with the portion 13 and a lower end surface 2143 connected to the inner wall surface 212 are formed in this order. The protruding surface 2141 is a surface protruding from the flange portion 13 to the washing side, and a groove 216 extending in the longitudinal direction is formed. A plate-like apron member 3 extending downward is fitted in the groove 216. The apron member 3 covers the first long wall portion 121 of the bathtub body 1 so as not to be seen from the washing side.

  The contact surface 2142 is a surface that is continuous with the protruding surface 2141, and a flat surface that contacts the upper surface of the flange 13 and a curved surface that contacts the connecting portion between the flange 13 and the first long wall 121 from the outside toward the inside , It is formed to be continuous in this order. The curved surface is formed in an arc shape extending downward as it goes inward. The lower end surface 2143 is formed to connect the curved surface of the contact surface 2142 and the inner wall surface 212, and is formed of a generally flat inclined surface extending upward as it goes inward.

  Next, the second long side portion 22 will be described. As shown in FIG. 6, the second long side portion 22 has an upper surface 221, an inner wall surface 222 facing the inside of the bathtub, an outer wall surface 223 facing the outside of the bathtub, a lower surface 224, and the same as the first long side portion 21. It has a pair of side wall surfaces 225 at both ends in the longitudinal direction, and is formed in a rectangular parallelepiped shape as a whole. The differences from the first long side portion 21 are as follows.

  First, the width is narrower than the first long side portion 21 and the amount of protrusion to the outside is small. Further, the configuration of the lower surface 224 is different from the first long side portion 21. That is, on the lower surface 224 of the second long side portion 22, the protrusion 2241, the contact surface 2242 in contact with the flange 13, and the lower end surface 2243 connected to the inner wall 222 are arranged in this order from the outside to the inside. It is formed. The protruding portion 2241 protrudes downward so as to be continuous with the outer wall surface 223, and the protruding portion 2241 is adapted to engage with the edge portion 14 described above. The contact surface 2242 is formed such that a flat surface in contact with the upper surface of the flange portion 13 and a curved surface in contact with the connection portion between the flange portion 13 and the second long wall portion 122 are continuous in this order from outside to inside ing. The curved surface is formed in an arc shape extending downward as it goes inward. The lower end surface 2243 is formed to connect the curved surface of the contact surface 2242 and the inner wall surface 222, and is formed of a generally flat inclined surface extending upward as it goes inward.

  Thus, although the 2nd long side part 22 protrudes outside the flange part 13, the protruding outer wall surface 223 contacts the wall surface 5 of a bathroom. That is, as described above, a gap is formed between the edge portion 14 and the wall surface 5 of the bathroom, but the gap is filled by the second long side portion 22.

<1-2-2. Short side>
Next, the short side portions 23 and 24 will be described with reference to FIG. As shown in FIG. 7, since the two short side portions 23 and 24 have the same configuration, only one will be described. That is, the short side portion 23 has an upper surface 231, an inner wall surface 232 facing the inside of the bathtub, an outer wall surface 233 facing the outside of the bathtub, a lower surface 234, and a pair of side wall surfaces at both ends in the longitudinal direction. , Is formed in a rectangular shape. The side wall surfaces are surfaces fixed to the inner wall surfaces 212 and 222 of the long side portions 21 and 22.

  The thickness of the short side portion 23 is slightly smaller than that of the long side portions 21 and 22, and the upper surface 231 is disposed slightly lower than the upper surfaces 211 and 221 of the long side portions 21 and 22. Further, the inner wall surface 232 of the short side portion 23 is inclined in an arc shape, and is formed to extend inward as it goes downward. In the lower surface 234 of the short side portion 23, a contact surface 2342 in contact with the flange portion 13 and a lower end surface 2343 connected to the inner wall surface 232 are formed in this order. Unlike the second long side portion 22, no protruding portion is provided, but the other specific configuration is substantially the same as the second long side portion 22, so the description will be omitted.

  Thus, although each short side part 23 and 24 protrudes outside the flange part 13, the protruding outer wall surface 233 contacts the wall surface 5 of the bathroom. As described above, a gap is formed between the edge portion 14 and the wall surface 5 of the bathroom, but the gap is filled with the short side portions 23 and 24.

1-2-3. Structure of connecting part of long side and short side>
Next, the structure of the connection part of the long side parts 21 and 22 and the short side parts 23 and 24 is demonstrated, referring FIG.8 and FIG.9. FIG. 8 is an enlarged view of a connection portion between the second long side and the short side, and FIG. 9 is a cross-sectional view taken along the line E-E of FIG. As described above, the ridges 18 extending in the vertical direction are formed in the side wall portion 12 of the bathtub body 1 at the connecting portion of the long wall portions 121 and 122 and the short wall portions 123 and 124. Therefore, a notch 28 is formed in the connecting portion between the second long side 22 and the short side 23 so as not to interfere with the protrusion 18. Although the connection between the second long side 22 and one short side 23 is described here, the connection structure between the first long side 21 and the short sides 23 and 24 is the same.

  Specifically, as shown in FIG. 8, both side portions of the second long side portion 22 and the lower end surfaces 2243 and 2343 of the short side portion 23 are obliquely cut, and are formed between the inclined portions 228 and 238. The protruding portion 18 is fitted in the recessed portion (notched portion) 28 to be formed. Further, in the second long side portion 22 and the short side portion 23, points X at the upper end of the notched lower end faces 2243 and 2343 contact each other. Thereby, the interference between the top plate member 2 and the protruding portion 18 can be eliminated, and the lower end surfaces 2243 and 2343 of the second long side portion 22 and the short side portion 23 can be made to appear to be connected smoothly.

<1-3. Connection structure between bathtub body and top plate member>
Next, the connection structure between the bathtub body 1 and the top plate member 2 will be described with reference to FIG. FIG. 10 is a cross-sectional view showing the connecting structure of the top plate members of the bathtub body. In addition, such a connection structure may be provided in any position of the flange part 13 of the bathtub main body 1, and the top-plate member 2, and the number in particular is not limited, either. Preferably, it is provided at every 20 to 50 cm and the corner of the flange portion 13 or the top plate 2. Below, the connection structure of the 2nd long side part 22 of the top-plate member 2 and the flange part 13 is demonstrated as an example.

  First, as described above, mounting holes 15 are formed at a plurality of locations in the flange portion 13 of the bathtub body 1. In order to correspond to this, as shown in FIG. 10, a plurality of fixing portions 4 are attached to the top plate member 2. Each fixing portion 4 includes a projecting member 41 fitted in the mounting hole 15 and a support member 42 for supporting the projecting member 41. The projecting member 41 includes a rod-like portion 411 formed in a circular shape in cross section, and a head portion 412 formed on the upper end of the rod-like portion 411. The rod-like portion 411 has a diameter larger than the inner diameter of the attachment hole 15 of the flange portion 13 and is a portion pressed into the attachment hole 15 as described later. The lower end portion of the rod-like portion 411 is formed in a hemispherical shape to facilitate positioning in the mounting hole 15. Further, the head portion 412 is formed in a disk shape that is wider than the rod-like portion 411 and specifically has a large diameter. However, the upper surface thereof is formed in an arc shape in cross section such that the thickness becomes larger as it goes to the center. The projecting member 41 can be made of, for example, an elastically deformable resin material or the like.

  On the other hand, the support member 42 includes a plate-like base 421 fixed to the recess 131 formed on the lower surface 224 of the second long side 22 and a holding part 422 attached to the base 421. The holding portion 422 is formed in a cup shape so as to form a space portion with the base portion 421, and an insertion hole 423 penetrating the holding portion 422 is formed on the bottom surface. Then, the head portion 412 of the projecting member 41 is accommodated in the space portion, and the rod-like portion 411 is inserted into the insertion hole 423. The height in the vertical direction of the space portion is substantially the same as the thickness of the head portion 412, whereby the projecting member 41 is held so as not to move up and down in the space portion. The diameter of the insertion hole 423 is smaller than that of the head portion 412 but larger than that of the rod-like portion 411. Therefore, the projecting member 41 can be prevented from coming out of the insertion hole 423, and the rod-like portion 411 moves in the horizontal direction in the insertion hole 423. Therefore, the projecting member 41 is held by the supporting member 42 so as to be movable by about 1 mm to 1 cm in the horizontal direction, although it does not move up and down. Depending on the manufacturing accuracy, the rod-like portion 411 moves in a specific direction in the horizontal direction, specifically, in the longitudinal (extension) direction or width direction of the long sides 21 and 22 and the short sides 23 and 24. You may come to Further, the head portion 412 of the projecting member 41 has a large central thickness, and this portion is mainly in contact with the base portion 421. Therefore, the frictional resistance at the time of the protrusion member 41 moving in the support member 42 is reduced, and it can move now smoothly.

<2. Assembly of bathtub>
First, the bathtub body 1 is placed in the bathroom. As described above, the second long wall 122 and both short walls 123 and 124 of the side wall 12 are disposed to face the wall 5 of the bathroom, and the corresponding edge 14 and the wall 5 of the bathroom For example, as shown in FIG. 6 and FIG.

  Next, the top plate member 2 is attached. First, the top plate member 2 is disposed on the flange portion 13 of the bathtub body 1, and the tip end portion of the projecting member 41 is positioned so as to be fitted into the mounting hole 15. At this time, the tip end portion of the projecting member 41 is formed in a hemispherical shape, so it is easy to fit in the mounting hole 15. At this time, for example, as shown in FIG. 11, even if the tip end of the projecting member 41 is not completely fitted in the mounting hole 15, the projecting member 41 is held so as to be movable in the horizontal direction. When 2 is pressed, the projecting member 41 moves in the horizontal direction so that the hemispherical portion at the tip end fits into the mounting hole 15. Then, when the top plate member 2 is further pressed downward, as shown in FIG. 12, the projecting member 41 is press-fit into the mounting hole 15, and the top plate member 2 is fixed to the bathtub body 1.

  At this time, the second long side 22 and both short sides 23 and 24 of the top plate member 2 fill the edge 14 and the wall surface 5 of the bathroom as shown in FIGS. 22 and the outer wall surfaces 233 and 243 of the short side portions 23 and 24 are disposed in contact with the wall surface 5 of the bathroom. Then, finally, the apron member 3 is fitted into the groove 216 of the first long side portion 21 of the top plate member 2 to cover the first long wall portion 121 of the bathtub main body 1, as shown in FIG. Assembly is complete.

<3. Feature>
As described above, according to this embodiment, the following effects can be obtained.
(1) The flange portion 13 of the bathtub body 1 is covered by the top plate member 2, and in particular, since the inner wall surfaces 212, 222, 232, 242 of the top plate member 2 protrude inside the bathtub body 1, the flange portion 13 and the connecting part of the top plate member 2 can be hidden, and the appearance can be improved. Further, while the lower end faces 2143, 2243, 2343 and 2443 of the top plate member 2 are inclined obliquely downward, the connecting portion between the flange portion 13 and the side wall portion 12 is covered to extend to the inner surface of the side wall portion 12. As a result, dirt is less likely to accumulate and cleaning can be facilitated.

(2) The top plate member 2 is formed as a separate member from the bathtub body 1 and is formed by combining a plurality of long side portions 21 and 22 and short side portions 23 and 24 having a rectangular parallelepiped shape. Therefore, a sheet with high designability such as wood grain can be attached or wound on the surfaces of the long side portions 21 and 22 and the short side portions 23 and 24. Therefore, the decorativeness of the top plate member 2 can be greatly improved. For example, the long side portions 21 and 22 and the short side portions 23 and 24 can be formed by extrusion molding of a resin material such as a foam material, and a sheet of acrylic or ABS for decoration, an adhesive, heat treatment, etc. Can be pasted by

(3) Since only the top plate member 2 can be removed, only the top plate member 2 of the bathtub can be replaced. Therefore, it is not necessary to replace the entire bath, which has high workability and can reduce the cost of replacement. For example, although it is necessary to remove piping for additional cooking etc. in order to remove the bathtub main body 1, since such an operation | work is unnecessary, construction property is high.

(4) Since a gap is formed between the edge portion 14 of the bathtub body 1 and the wall surface 5 of the bathroom, work can be performed while putting a hand in this gap. Therefore, the workability can be enhanced. On the other hand, the outer wall surface 223 of the second long side 22 and the outer wall surfaces 233 and 243 of the short sides 23 and 24 of the top plate member 2 are in contact with the wall 5 and no finger can be inserted therebetween. Therefore, for example, it is almost impossible for a general user to pull up the top plate member 2 straight and remove it. Therefore, it can prevent that a top plate member 2 rattles.

(5) Since the projecting member 41 provided on the top plate member 2 is held movably in the horizontal direction, for example, as shown in FIG. 10, the axial center of the projecting member 41 and the mounting hole 15 Even if the axial center of the projection is shifted, the axial center of the both is aligned by moving the projecting member 41 in the horizontal direction, so that the projecting member 41 can be fitted into the mounting hole 15 correctly. Therefore, the top plate member 2 and the bathtub body 1 can be securely fixed.

(6) The projecting member 41 is fitted into the mounting hole 15 by press-fitting, so that it is possible to fix it to the bathtub body 1 only by pushing the top plate member 2. The work of fixing with bolts or the like becomes unnecessary, and the workability can be enhanced.
