The male screw portion 31 is formed on the outer peripheral surface of the inner metal fitting 29, and is screwed into the female screw portion 19 formed on the inner peripheral surface of the outer cylinder 13 of the outer metal fitting 12. The seal ring 32 is inserted into the male screw portion 31 and comes into contact with the outer surface of the flange 30. When the inner metal fitting 29 is attached to the outer metal fitting 12, the seal ring 32 is tightly attached to the inner surface of the bathtub side wall 25 so as to be watertight.

The pair of fastening projections 33 is
Is provided on the inner surface of a
The inner fitting 29 can be securely fastened to the outer fitting 12. The annular groove 34 is provided on the outer peripheral surface of the flange 31 of the inner metal fitting 29, and a filter member (not shown) is attached thereto.

As shown in FIGS. 1 to 3, an attachment jig 35 for attaching the bathtub circulation fitting 11 to the bathtub side wall 25 as described above is formed by a single metal round bar having an arc-shaped tip. The jig main body 36 is formed to be bent in an elongated annular shape, and the grip mounting portion 37 is formed by bending the base end portion of the main body 36 by 90 degrees and spot-welding. The main body 36 of the mounting jig 35 has a predetermined elasticity in the width direction thereof, and has a U-shaped locking projection 38 and an arcuate arc-shaped portion 39 formed narrower at the distal end. Consisting of The width D between the locking projections 38 (FIG. 2)
The reference numeral) is a portion formed to be the widest in comparison with the arc-shaped portion 39 side and the grip attaching portion 37 side of the main body 36.

When the main body 36 of the mounting jig 35 is pushed into the inner cylinder 14 of the bathtub circulation fitting 11, the main body 36 is pressed against the inner peripheral surface of the inner cylinder 14 by its elastic force so as not to come off. It has become. When pulling out the mounting jig 35 from the inside of the inner cylinder 14, the jig 35 can be easily pulled out by pulling out the jig 35 in a state where the main body 36 is pressed so as to sandwich it in the width direction (two-dot chain line in FIG. 2). . The covering portion 40 made of vinyl chloride resin covers the grip attaching portion 37 and the base end of the main body 36 so that it can be easily grasped by hand.

As shown in FIG. 2, the locking projection 3
The width of 8 is formed so as to be the largest at a position away from the distal end by a predetermined distance toward the proximal end, and when the jig body 36 is fitted into the inner cylinder 14 of the bathtub circulation fitting 11 as shown in FIG. The locking projection 38 is engaged with the inner peripheral surface of the inner cylinder 14 so as not to come off.

Next, a method of attaching the bathtub circulation fitting 11 to the side wall 25 of the bathtub using the attachment jig 35 will be described. First, outside the bathroom 22, the main body 36 is supported by grasping the holding portion 37 of the mounting jig 35 with a hand, and the main body 36 is pushed into the inner cylinder 14 of the outer fitting 12 from the arc-shaped portion 39 side. At this time, the main body 36 can be easily pushed in by being pushed firmly against the elastic force while being pressed. Next, as shown in FIG. 4, in this state, the grip mounting portion 37 of the mounting jig 35 is passed through the opening 24 of the bathroom 22 and locked in the mounting hole 26 of the side wall 25 of the bathtub. Then, in that state, the outer fitting 12 is placed there, and the worker moves into the bathroom 22 and enters the bathtub 18.

As shown in FIG. 5, the holding portion 37 of the mounting jig 35 is gripped from the inside of the bathtub 18 and pulled, and the inner metal fitting 29 is inserted into the jig body 36. And Figure 6,
As shown in 7, tub 1 a sealing member 21 of the outer member 12
8 and the inner fitting 29
The male screw portion 31 is inserted into the mounting hole 26 of the side wall 25 of the bathtub 18 and screwed into the female screw portion 19 on the inner surface of the outer cylinder 13 of the outer fitting 12. At this time, due to the elastic force of the main body 36 of the mounting jig 35, the widest locking projection 38 is moved to the outer fitting 12.
Because it is pressed against and engaged with the inner surface of the inner cylinder 14 of
During these operations, the outer fitting 12 can be kept in close contact with the side wall 25 of the bathtub 18 .

As shown in FIG. 8, after the male screw portion 31 of the inner metal fitting 29 is screwed into the female screw portion 19 of the outer cylinder 13 of the outer metal fitting 12, the jig body 36 is moved inward against its elastic force. The jig 35 is pulled out from the outer cylinder 13 of the outer metal fitting 12 in a state where the jig 35 is pressed so as to be able to be pinched. Note that the jig body 36 can be pulled out of the inner cylinder 14 as it is while holding the grip mounting portion 37.

Thereafter, a fastening jig (not shown) is engaged with the fastening projection 33 of the inner fitting 29 and rotated to securely fasten the inner fitting 29 to the outer fitting 12. Further, a filter member (not shown) is attached to the annular groove 34 of the flange 30 of the inner fitting 29. In this manner, the bathtub circulation fitting 11 can be mounted in the mounting hole 26 of the bathtub side wall 25.

As described above, this embodiment has the following advantages. (1) The fitting jig 35 can be easily engaged with the outer fitting 12 simply by pushing the fitting jig 35 into the inner cylinder 14 of the outer fitting 12 based on the elastic force of the main body 36. (2) When pulling out the mounting jig 35 from the inner cylinder 14 of the outer metal fitting 12, it can be easily performed simply by pulling out the main body 36 by gently grasping both sides thereof. (3) Accordingly, the bathtub circulation fitting 11 composed of the outer fitting 12 and the inner fitting 29 can be easily and quickly mounted on the mounting hole 26 of the bathtub side wall 25. (4) Since the arc-shaped portion 39 is provided at the tip of the mounting jig 35, when the jig 35 is inserted into or extracted from the inner cylinder 14 of the outer metal fitting 12, the inside of the inner cylinder 14 is removed. O
The possibility that the ring 28 is damaged can be prevented. (5) The mounting jig 35 can be easily manufactured by bending one metal rod and spot welding the base end thereof, thereby reducing the manufacturing cost. (6) By using the mounting jig 35, the outer metal fitting 1
The bathtub circulation mouthpiece 11 consisting of the inner fitting 2 and the inner fitting 29 can be attached to the attachment hole 26 of the bathtub side wall 25 alone, so that the attachment work can be facilitated and the construction cost can be reduced.
