  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

[First Embodiment]
In FIG. 1 to FIG. 3, the bathtub and apron fixing structure S <b> 1 according to the present embodiment is used in a unit room including, for example, a bathtub 10 and a washing place (not shown). This bathtub and apron fixing structure S1 includes an apron 12, a bathtub fixing portion 14, and a screw 16 as an example of a fixing member.

  In FIG. 1, the apron 12 is a resin panel member disposed between the bathtub 10 side and the washing place side. From the apron main body 18 and the apron main body 18 that can cover at least a part of the side surface of the bathtub 10. An apron fixing part 20 extending upward is provided.

  The apron body 18 is a panel that extends in the longitudinal direction of the bathtub 10 (in the direction of the arrow L), for example. In the longitudinal direction, both end portions 22 of the apron main body portion 18 protrude to the opposite side to the bathtub 10 side. Thereby, the apron main-body part 18 is formed in the substantially U shape by planar view. Another apron (not shown) may be attached between the both end portions 22. In this case, the apron 12 becomes an inner apron located inside another apron, and the other apron becomes an outer apron.

  The apron fixing portion 20 is a fixing portion on the apron 12 side that extends upward from both end portions 22 of the apron main body portion 18 and has a vertical surface 20A closer to the bathtub 10 side than the washing surface side vertical surface 22A of both end portions 22. doing. The washing surface side vertical surface 22A and the vertical surface 20A have a stepped shape. This step shape is provided in consideration that the apron fixing part 20 covers a bathtub fixing part 14 described later. Upper surfaces 22C of both end portions 22 are in close proximity to or in contact with the lower end of bathtub fixing portion 14 (the lower end of general portion 14B described later). An intermediate step 24 having an intermediate height of the step shape is provided at the lower end of the vertical surface 20A. An upper surface 20 </ b> B extending to the bathtub 10 side is provided at the upper end of the apron fixing portion 20. Between the apron fixing | fixed part 20 and the bathtub fixing | fixed part 14, the sheet-like water stop member 28 is arrange | positioned, for example.

  On the upper side from the apron main body portion 18, an insertion portion 32 that covers the flange portion 30 at the upper peripheral edge of the bathtub 10 is provided. Both ends of the insertion portion 32 in the direction of the arrow L are connected to the side surface 20C of the apron fixing portion 20. The insertion part 32 and the apron fixing part 20 are inserted into the flange part 30 of the bathtub 10 from below. A water stop member (not shown) is disposed between the insertion portion 32 and the flange portion 30. This water stop member may be obtained by extending the water stop member 28 in the longitudinal direction of the bathtub 10 (the direction of the arrow L).

  The bathtub fixing part 14 is a fixing part on the bathtub 10 side that extends downward from the flange part 30 at the upper peripheral edge of the bathtub 10 and overlaps the apron fixing part 20. The bathtub fixing part 14 is provided at both ends of the flange part 30 in the longitudinal direction (arrow L direction) of the bathtub 10 corresponding to the position of the apron fixing part 20.

  The bathtub fixing part 14 is formed with a concave part 14 </ b> A that is recessed toward the bathtub 10. This recessed part 14A has comprised the level | step difference shape near the bathtub 10 side with respect to the general part 14B. Therefore, the concave portion 14A can be rephrased as a stepped portion. In addition, the recess 14A can be rephrased as a mounting seat for the auxiliary member 34 described later.

  The recess 14A reaches both sides of the bathtub fixing part 14 in the longitudinal direction of the bathtub 10 (arrow L direction). Further, the concave portion 14 </ b> A reaches the upper end of the bathtub fixing portion 14. However, as shown in FIG. 3, the recess 14 </ b> A does not reach the lower end of the bathtub fixing portion 14. That is, in the bathtub fixing part 14, the upper side of the general part 14B is a concave part 14A, and one side of the concave part 14A is adjacent to the general part 14B. The configuration of the recess 14A is not limited to this, and two or more sides of the recess 14A may be adjacent to the general portion 14B. For example, the upper and lower portions of the recess 14A may be adjacent to the general portion 14B, and the recess 14A may be surrounded by the general portion 14B. In this case, the alignment of the auxiliary member 34 is facilitated, and the displacement of the auxiliary member 34 can be suppressed.

  An auxiliary member 34 that fills the recess 14A is disposed in the recess 14A. The auxiliary member 34 is a rectangular reinforcing plate, for example. The material of the auxiliary member 34 is, for example, stainless steel or resin. The dimension of the auxiliary member 34 corresponds to the dimension of the recess 14A. The thickness of the auxiliary member 34 substantially matches the depth of the recess 14A (the difference in height between the general portion 14B and the recess 14A). The auxiliary member 34 is formed with a through hole 34A through which the screw 16 is passed, and a counterbore part 34B that is formed at the edge of the through hole 34A and in which the head 16A of the screw 16 is accommodated. Thereby, the screw 16 does not protrude from the concave portion 14 </ b> A of the bathtub fixing portion 14 to the opposite side (washing area) of the bathtub 10 side.

  In the present embodiment, a through hole 34 </ b> C through which the screw 17 shorter than the screw 16 is passed is formed in the auxiliary member 34 side by side above the through hole 34 </ b> A. A counterbore 34D in which the head 17A of the screw 17 is accommodated is formed at the edge of the through hole 34C. When the nominal diameters of the screws 16 and 17 are the same, the through holes 34A and 34C have the same configuration, and the counterbore portions 34B and 34D have the same configuration.

  The screw 16 is, for example, a flat head screw that penetrates at least the recess 14A in the bathtub fixing portion 14 and fixes the bathtub fixing portion 14 and the apron fixing portion 20 to each other. As shown in FIG. 3, the screw 16 has a length that reaches the apron fixing portion 20. In this embodiment, a screw 17 is used in addition to the screw 16. The screw 17 is a member that fixes the auxiliary member 34 to the bathtub fixing portion 14, and is screwed to the bathtub fixing portion 14 above the screw 16. The screw 17 does not reach the apron fixing part 20. The bathtub fixing part 14 and the apron fixing part 20 may be fixed to each other by using two screws 16. In this case, the short screw 17 may not be used.

  As shown in FIG. 3, the auxiliary member 34 is flush with the general portion 14 </ b> B except the concave portion 14 </ b> A in the bathtub fixing portion 14 and the apron main body portion 18. Specifically, the auxiliary member 34 is flush with the washing surface-side vertical surface 22A at both end portions 22 of the apron main body portion 18. “Same surface” means that there is no step between each part and it is flat.

  In the bathtub fixing part 14, the recess 14A does not reach the lower end of the bathtub fixing part 14 (the lower end 14C of the general part 14B). Accordingly, the auxiliary member 34 that fills the recess 14 </ b> A does not reach the lower end of the bathtub fixing portion 14. In other words, the auxiliary member 34 does not reach the lower end of the apron fixing portion 20, specifically, the intermediate step 24. A general portion 14B is provided below the recess 14A, and the lower end 14C of the general portion 14B and the upper end surfaces 22B of both end portions 22 of the apron main body 18 are adjacent to each other vertically with, for example, a water stop member 28 interposed therebetween. doing. Between the lower end 14C and the upper end surface 22B, water stop processing such as coking may be further performed.

  In FIG. 3, the wall portion 36 of the unit room is disposed adjacent to the flush portion extending from the auxiliary member 34, the general portion 14 </ b> B, and the washing room side vertical surface 22 </ b> A.
