  By forming the bathtub apron 4 with such dimensions, the inner piece 6b of the lower fitting recess 6 becomes an obstacle, and the bathtub apron 4 cannot be taken in and out between the hanging piece 1a and the floor pan weir 3 from the washing place 2c side. There is nothing.

  Further, the apron joint material 7 is extended to the bathroom wall surfaces 9 and 9 located on both sides of the bathtub apron 4, and the space between the side edge 4a of the bathtub apron 4 and the bathroom wall wall 9 facing the side edge 4a is shielded. It is preferable that the side joint material 10 to be mounted is slidable up and down on the side end portion 4b of the bathtub apron 4 below the apron joint material 7 so that the side joint material upper end 10a abuts on the apron joint material lower end 7c.

  Thus, the side joint material 10 is provided from the side end 4b of the bathtub apron 4 to the bathroom wall 9 facing the bathtub apron 4, and is slidable up and down with respect to the bathtub apron 4. In addition to preventing water from entering the mounting portion 2b, if the side joint material 10 is slid upward, the apron joint material 7 is pushed upward, and the drooping piece 1a and the upper fitting concave portion 5 are pushed. The press-fitted apron joint material 7 can be easily removed. Therefore, it is not necessary to separately provide a configuration for removing the apron joint material 7.

  The present invention provides a bathtub apron mounting structure with a sufficient waterproof structure that does not allow a gap between the bathtub flange and the bathtub apron even when a force is applied to the bathtub apron from the washing side, and the bathtub apron is attached to the bathtub flange. There is no need to separately provide a configuration for attachment, and an effect is provided that a detachable bathtub apron attachment structure that is easy to attach can be provided.

  Moreover, the effect that the attachment structure of the detachable bathtub apron which it is easy to attach can be provided by comprising a bathtub apron with the dimension which can be taken in and out freely between a hanging piece and a floor pan dam.

  In addition, the side joint material that prevents water from entering the bathtub mounting part from the side of the bathtub apron is slidable up and down, so that not only the waterproof property is improved, but also a configuration for removing the apron joint material is provided. Without removing the apron joint material, it is possible to easily remove the bathtub apron.

It attaches over the bread dam 3 and covers the washing room 2c side behind the bathtub. Bathroom wall surfaces 9 and 9 are provided on both sides of the bathtub apron 4 with the bathtub apron 4 attached to the hanging piece 1a and the floor pan weir 3, and both the hanging piece 1a and the floor pan weir 3 are It is provided over the whole area between both bathroom wall surfaces 9 and 9. Further, the floor pan weir 3 has a flat upper end surface 3a, the front surface is substantially perpendicular to the floor pan 2, and the rear surface is slightly inclined away from the front surface as approaching downward.

  The bathtub apron 4 is provided with protrusions having a substantially L-shaped cross section over the entire left and right direction on the upper and lower portions of the rear surface of the flat panel panel. An upper fitting concave portion 5 that opens toward the bottom is formed, and a lower fitting concave portion 6 that opens downward is formed by a projection having a substantially L-shaped cross section at the lower portion and a flat panel panel on the front side thereof. Here, the flat plate panel on the front side of the upper fitting recess 5 is defined as an outer piece 5a, and the protrusion portion having a substantially L-shaped cross section on the rear side of the upper fitting recess 5 facing the outer piece 5a is defined as an inner piece 5b. The other part of the protrusion having an approximately L-shaped cross section of the upper fitting recessed part 5 connecting the 5a and the inner piece 5b is defined as a connecting piece 5c. Further, the flat panel on the front side of the lower fitting recess 6 is defined as an outer piece 6a, and the protrusion portion having a substantially L-shaped cross section on the rear side of the lower fitting recess 6 facing the outer piece 6a is defined as an inner piece 6b. The other part of the protrusion having a substantially L-shaped cross section of the lower fitting recess 6 connecting the inner piece 6b and the inner piece 6b is defined as a connection piece 6c.

  The inner piece 6b of the lower fitting recess 6 is inclined so as to be away from the opposed outer piece 6a as it approaches the lower side. By inclining in this way, the inner piece 6b serves as a guide piece when the lower fitting recess 6 is fitted to the floor pan weir 3 without being aligned with the right position. The lower fitting recess 6 of the lower end of the bathtub apron 4 is guided. On the other hand, the inner piece 5b of the upper fitting recess 5 is substantially parallel to the opposite outer piece 5a.

  The connecting piece 5c and the connecting piece 6c are provided substantially perpendicular to the flat panel of the bathtub apron 4, and are connected from the connecting portion between the upper surface of the connecting piece 5c of the upper fitting recess 5 and the rear surface of the outer piece 5a. The distance in the front-rear direction to the connecting portion between the upper surface of the piece 5c and the front surface of the inner piece 5b is set wider than the thickness in the front-rear direction of the drooping piece 1a. When the upper fitting recess 5 is fitted, the fitting is facilitated. The distance in the front-rear direction from the connecting portion between the lower surface of the connecting piece 6c of the lower fitting recess 6 and the front surface of the inner piece 6b to the connecting portion between the lower surface of the connecting piece 6c and the rear surface of the outer piece 6a is the floor pan weir 3 is substantially the same as the length of the upper end surface 3a in the front-rear direction, and when the lower fitting recess 6 is attached to the floor pan weir 3, the upper portion of the outer piece 6a and the upper portion of the inner piece 6b Are fitted so as to hold them. At this time, the upper end surface 3a of the floor pan weir 3 and the lower surface (back surface 6c1) of the connection piece 6c of the lower fitting recess 6 abut. In addition, the connection piece 5c of the upper fitting recess 5 is provided with a plurality of drain holes 8 in the center in the front-rear direction and extending in the left-right direction. Even if water enters from a gap with the piece 1a, it does not accumulate on the connection piece 5c.

  In addition, a curved portion 5b2 that curves to the front side is provided over the entire left and right direction at the upper portion of the inner piece 5b of the upper fitting recess 5. When the apron joint material 7 is inserted into the gap formed between the outer piece 5a of the upper fitting recess 5 and the hanging piece 1a by fitting the upper fitting recess 5 into the hanging piece 1a, the outer piece 5a of the upper fitting recess 5; The drooping piece 1a is held between the curved portion 5b2 of the inner piece 5b of the upper fitting recess 5 through the apron joint material 7.
