Example 1
The bathroom according to the first embodiment includes various bathroom members such as a bathtub 1, a bathtub pan 2, a washing pan 3 and an apron 4. FIG. 1 is an exploded view of these. However, about the bathtub pan 2, the specification (specification shown in FIG. 2) fastened with another bathroom member without using this and the specification which fastens all these three bathroom members using the bathtub pan 2 (FIG. 3) And the specifications shown in

First, specifications in which the bathtub pan 2 is not used will be described (see FIGS. 1 and 2).
The washing pan 3 is horizontally mounted in a state of being separated from the floor surface of the housing not shown. As shown in FIG. 2, a peripheral wall 5 is formed to rise upward at the peripheral edge of the washing pan 3. A projecting wall 6 extends outward and horizontally over the entire length of an upper end edge of a portion of the peripheral wall 5 facing the bathtub 1. A hanging wall 7 is continuously formed substantially downwardly along the entire length of the extending end edge of the overhanging wall 6, and a gap is held between the hanging wall 7 and the peripheral wall 5. At the lower end edge of the hanging wall 7, a holding wall 8 is formed extending outward (in a direction approaching the bath 1) and horizontally horizontally over the entire length. The entire lower surface of the holding wall 8 is formed flush, but the upper surface side is thicker than the root side, and the holding portion 9 having a level difference with the root side is formed.

  A tapered surface 10 is formed on the side facing the bath 1 in the holding portion 9 so as to be inclined downward and gradually inward. A plurality of through holes 11 are formed longitudinally in the holding portion 9. The through holes 11 are arranged at a constant pitch along the longitudinal direction of the holding portion 9. As shown in FIGS. 2 and 5, a plurality of clip NCs with nuts are attached to the holding portion 9 in correspondence to the respective through holes 11.

  The clip 12 is made of, for example, a synthetic resin, and as shown in FIG. 4, the substrate 13 and the side plate 14 obliquely rising with a gradient adapted to the gradient of the tapered surface 10 described above from one side edge of the substrate 13 And a top plate 15 extending from the upper end edge of the top of the substrate 13 so as to face the upper side of the substrate 13.

  A through hole 19 through which the first fastening portion 17 of the fastening bolt 16 is inserted is formed through the center of the top plate 15. Moreover, the upper clamping piece 20 is formed in cross-sectional substantially V-shape in the front-end edge of the top plate 15 over the full length.

  On the other hand, at the central portion in the longitudinal direction of the tip end side of the substrate 13, a groove 21 extending and penetrating in a U-shape from the tip end back to the side plate 14 is cut out. The central axis of the through hole 19 is set to pass through the central line in the width direction of the groove 21.

  On both sides of the upper surface (inner surface) of the substrate 13 sandwiching the groove 21 in the longitudinal direction, nut supporting surfaces 23 are formed for guiding the flanged nut 22 backward and supporting it.

  Further, on the upper surface of the substrate 13, a stop portion 24 is formed so as to surround the deep portions of the groove portion 21 and the nut support surface 23 from three sides (the back and both sides in the width direction). The contact stopping portion 24 is formed on the inner surface (upper surface) of the substrate 13 so that the vertical cross section has an inverted L shape. Then, a part of the flange portion 22A of the flanged nut 22 can be accommodated in the inside thereof in a manner of press-fitting. The flange portion 22A is sandwiched between the bottom surface and the ceiling surface in the stopper portion 24, and is in a state of being prevented from being removed upward.

  A V-shaped notch 25 is formed at the center in the width direction of the portion of the contact stop 24 disposed along the inner surface of the side plate 14. The V-shape of the notched portion 25 is formed at an angle so as to fit to two adjacent outer surfaces of the hexagonal nut portion 22B of the flanged nut 22. As a result, in a state where the flanged nut 22 is accommodated in the stopper 24, the hexagonal nut 22 B protrudes upward from the stopper 24, and the edge of the notch 25 and the stopper The flanged nut 22 is accommodated in a detented state because the side edges of the portion facing opposite in parallel in the width direction of 24 and the four continuous side surfaces of the nut portion 22B fit and come into contact with each other. become.

  A pair of lower sandwiching pieces 26 is provided at the tip edge of the substrate 13 across the groove 21 in the width direction. Both lower clamping pieces 26 project toward the washing pan 3 side. Both lower clamping pieces 26 are formed in a V shape opposite to the upper clamping piece 20.

  The distance between the upper clamping piece 20 and the lower clamping piece 26 in the height direction when the clip 12 is in a substantially natural state is narrower than the height dimension of the holding portion 9. When the clip NC with a nut is attached to the holding portion 9, the height interval of the upper and lower holding pieces 20 and 26 is elastically pushed and spread from the bath 1 side while being spread. Then, when the upper clamping piece 20 passes through the holding portion 9, the upper clamping piece 20 elastically returns together with the top plate 15 and is caught on the step between the holding portion 9 and the holding wall 8, whereby the clip NC with nut Is attached to the holder 9 in a state of being prevented from coming off. At this time, the mounting position of the clip 12 is adjusted so that the through hole 11 of the holding portion 9, the through hole 19 of the clip 12, and the screw hole (female screw) of the flanged nut 22 communicate coaxially.

  In addition, standing walls 26A are formed to protrude from the outer edge portions in the width direction of both lower holding pieces 26 so as to face each other. The upper surfaces of the lower lower clamping pieces 26 are in sliding contact with the lower surface of the holding portion 9 when the clip NC with a nut is mounted on the holding portion 9 so as to facilitate the mounting operation.

  As shown in FIG. 5, the fastening bolt 16 has a shaft portion 27 extending along the central axis, and a small diameter portion 28 coaxially protrudes at one end (lower end) thereof. The small diameter portion 28 plays the role of an insertion guide to the through hole 19 of the clip 12 and also has the role of making the operator know the upper and lower sides of the fastening bolt 16.

  A large diameter spacer 29 is integrally formed substantially at the center of the shaft 27. The spacer portion 29 is formed in a disk shape and has an outer diameter capable of being fitted to an insertion hole 30 (long hole) of the bath tub 2 described later. In the state where the spacer portion 29 is fitted into the insertion hole 30, the spacer portion 29 has a clearance in the lateral direction and the depth direction (the direction in which the elongated hole extends) in FIG. Further, the thickness of the spacer portion 29 is set to substantially the same size as the thickness of the mounting piece 31 of the bathtub pan 2. Therefore, the spacer unit 29 secures in advance a built-in space for the bathtub pan 2 (mounted 31 pieces) between the washing pan 3 and more specifically the upper surface of the clip 12 when the bathtub pan 2 is not provided. Play a role in

  In the shaft portion 27, a collar portion 32 (pressing portion) is continuously formed to protrude on the upper surface side of the spacer portion 29. The collar portion 32 is formed larger in diameter than the spacer portion 29, and a pressing surface 32A capable of pressing the upper surface of the mounting piece 31 of the bathtub pan 2 is formed on the lower surface thereof. Further, a hexagonal nut portion 33 is continuously formed on the upper surface side of the collar portion 32 in the drawing. The maximum outer diameter of the hexagonal nut portion 33 is set to be substantially equal to the outer diameter of the spacer portion 29.

  In addition, a first fastening portion 17 formed by an external thread is formed on one end side (small diameter portion 28 side) across the spacer portion 29, the collar portion 32, and the hexagonal nut portion 33 in the shaft portion 27, and the other end side In the same manner, a second fastening portion 18 formed by a screw is formed. The first fastening portion 17 is formed over a predetermined length range on the upper side of the small diameter portion 28, and the second fastening portion 18 is formed over substantially the same length range as the first fastening portion 17 from the opposite end. It is done.

  The apron 4 is attached to the side of the bathtub 1 opposite to the washing place. As shown in FIG. 1, in the apron 4, two illustrated operation window holes 36 are opened in parallel. As shown in FIG. 2, on the lower end side of the apron 4, a reinforcing rib 37 is formed so as to protrude toward the washing place side. Further, at the lower end of the apron 4, the connecting wall 38 extends substantially horizontally toward the bathtub 1 side. As shown in FIG. 2, the base portion of the connection wall 38 is a temporary storage portion 38A placed on the upper surface of the projecting wall 6 of the washing pan 3 when the apron 4 is fastened. In the connection wall 38, the front end side of the temporary placement portion 38A is one step lower than that of the temporary placement portion 38A, and a fastening portion 38B is formed. A circular insertion hole 39 through which the second fastening portion 18 of the fastening bolt 16 can be loosely inserted passes through the fastening portion 38B. The insertion holes 39 are arranged at a plurality of positions at the same pitch in accordance with the arrangement positions of the fastening bolts 16. The hole diameter of each insertion hole 39 is formed to be sufficiently larger than the outer diameter of the second fastening portion 18 to enable position adjustment when fastening the apron 4.

  Further, a positioning portion 38C is formed to be suspended along the longitudinal direction on the lower surface of the connection wall 38 and at the boundary portion between the temporary storage portion 38A and the fastening portion 38B. The positioning portion 38C is inserted between the hanging wall 7 of the washing pan 3 and the rising piece 35 (mounting piece 31) on the tip side of the bathtub pan 2 when the apron 4 is tightened. This enables the approximate positioning of the apron 4 with respect to 2 in the lateral direction shown in FIG.

  Next, an example of the fastening operation between the washing pan 3 and the apron 4 in the specification without the bathtub pan 2 will be described.

  First, the washing pan 3 is installed so as to float from the floor of the cabinet, and the clip NC with a nut is placed on the holding portion 9 of the washing pan 3 in advance. This operation is performed by fitting the clip NC with a nut to the holder 9 from the bathtub 1 side. At this time, the upper and lower holding pieces 20 and 26 expand and deform, and the upper holding piece 20 passes through the holding portion 9 and elastically returns, whereby the clip NC with a nut is held by the holding portion 9. At this time, the position of the clip 12 is adjusted so that the through hole 11 of the holding portion 9 and the through hole 19 of the clip 12 and the screw holes of the flanged nut 22 are coaxially positioned.

  Next, prior to the screwing of the fastening bolt 16, the temporary placement work of the bath 1 is performed. This operation is performed before screwing in the fastening bolt 16 in order to prevent the bottom of the bath 1 from being damaged by the interference with the fastening bolt 16.

  The fastening bolt 16 is inserted into the through hole 19 of the clip 12 and the through hole 11 of the holding portion 9 with the small diameter portion 28 side (the first fastening portion 17 side) as the lower end. Then, the first fastening portion 17 is screwed into the flanged nut 22 until the lower end of the spacer portion 29 abuts against the top plate 15 of the clip 12 by rotating the hexagonal nut portion 33. Thus, the fastening bolt 16 is held in the washing pan 3.

  Subsequently, fastening work of the apron 4 is performed. In this work, first, the washer 40 is fitted from the upper end of the fastening bolt 16 and placed on the upper surface of the hexagonal nut portion 33 of the fastening bolt 16. In that state, the upper end of the second fastening portion 18 is positioned while roughly positioning the apron 4 by inserting the positioning portion 38C of the apron 4 between the hanging wall 7 of the washroom pan 3 and the mounting piece 31 of the bathtub pan 2 Then, the insertion hole 39 is inserted, and the temporary storage portion 38A is placed on the upper surface of the projecting wall 6 of the washing pan 3 and the fastening portion 38B is placed on the upper surface of the washer 40.

After this, the worker inserts the washer 42 obtained from the washing place side through the window hole 36 of the apron 4 into the second fastening portion 18. And if the cap nut 41 is screwed in, the fastening operation of the washing pan 3 and the apron 4 is completed. The upper side of the apron 4 is attached to the bathtub 1 side.
Thus, the fastening operation of the washing pan 3 and the apron 4 in the specification without the bathtub pan 2 is completed.

  On the other hand, the fastening operation in the specification having the bathtub pan 2 will be described based on FIG. 3. First, the clip NC with a nut is held in the manner described above with respect to the holding portion 9 of the washing pan 3.

  Then, with the washing pan 3 installed, the bathtub pan 2 is temporarily placed on a support frame (not shown). As shown in FIG. 1, the bathtub pan 2 is composed of a bottom wall 2A and three side walls 2B surrounding the bottom wall 2A from three sides, and the side facing the upper side and the washroom side is substantially open.

  As shown in FIG. 3, a rising piece 34 is formed on the lower edge of the open side of the bathtub pan 2 over substantially the entire length. At the upper end portion of the rising piece 34, a mounting piece 31 is formed which protrudes substantially horizontally toward the washing place side. A plurality of insertion holes 30 pass through the mounting piece 31 at a constant pitch in the length direction. However, the insertion hole 30 is a long hole in the longitudinal direction. In addition, a pair of upright pieces 35 are erected and formed on both side edges in the longitudinal direction of the mounting piece 31 so as to be opposed to each other over the entire length.

  In the state where the bathtub pan 2 is temporarily placed, the mounting piece 31 is on the (receiving surface) of the top plate 15 of the clip 12 in a state where each insertion hole 30 is adjusted to communicate with the through hole 19 of the corresponding clip 12. It is placed. After the bathtub pan 2 is temporarily placed, the bathtub 1 is set above the bathtub pan 2.

Subsequently, the first fastening portion 17 is inserted into the through hole 30 of the bath tub 2, the through hole 19 of the clip 12, and the through hole 11 of the holding portion 9 while being guided by the small diameter portion 28 of the fastening bolt 16. Then, the first fastening portion 17 is screwed into the flanged nut 22 by rotating the hexagonal nut portion 33 of the fastening bolt 16. At this time, the spacer portion 29 is fitted into the insertion hole 30 of the bathtub pan 2 and abuts on the upper surface of the top plate 15 of the clip 12, and the pressing surface 32 A of the flange portion 32 is the attachment piece 31 of the bathtub pan 2. Hold down the top. That is, the spacer portion 29 is a receiving surface on which the bathtub pan 2 is placed, and the flange portion 32 serving as a pressing portion is positioned above the top plate 15 of the clip 12 by approximately the thickness of the mounting piece 31.
Thus, the fastening between the bathtub pan 2 and the washing pan 3 is completed by repeating the above-mentioned screwing operation for all the fastening bolts 16.

  In addition, although the fastening work of the apron 4 is done after this, the work is done in the same way as the work in the case of the specification without having the bathtub pan 2.

  As described above, in the first embodiment, even when the spacer 29 provided on the fastening bolt 16 does not have the bathtub pan 2, an assembly space for the bathtub pan 2 (mounting piece 31) is secured. And in the case of the specification having the bathtub pan 2, it has a structure (hip 32) for pressing the bathtub pan. Therefore, in both specifications with and without the bathtub pan 2, the two configurations can be handled with a common structure without changing the shape and positional relationship of the washing pan 3 and the apron 4.

  Moreover, in Example 1, since the collar part 32 which is a holding part with respect to the spacer part 29 and the bathtub pan 2 is integrally formed by the fastening bolt 16, while it contributes to the reduction of a number of parts, the effect which is excellent also in the handleability is there.

  Furthermore, in the first embodiment, since the flanged nut 22 is held in advance with respect to the washing pan 3, the screwing operation for the washing pan 3 can be performed from the upper side, and moreover, the one-hand operation is also possible. The effect is also obtained.
