Is pushed up at the bottom 8b of the bathtub 8, and the drain 4
Opens. Between the opening / closing operation part 50 and the drain cock 20,
As will be described later, a wire 6 for remote control is interposed, and the drain plug 20 is opened and closed via the wire 6 for remote control.

The lift mechanism of the remotely operated drain cock according to the present invention comprises:
The present invention relates to a mounting structure of a lift mechanism A serving as an outer receptacle on the side of the bathtub 8 of the wire 6 for remote control connecting the opening / closing operation section 50 and the drain plug 20. In FIG. 2, the drainage fitting 1 forms a screw portion 1 b on the outer periphery, and the screw portion 1 b is attached to the lower surface of the bathtub 8.
a, and the drain port 1 is brought into contact with the inside of the bathtub 8 and the drain port 4 is brought into contact with the back side of the bathtub 8, whereby the screw portion 1 b of the drain port fitting 1 is turned into a female screw of the drain port 4. The drainage fitting 1, the drainage port 4, and the bathtub 8 are fixed by being screwed on the portion 4 a. By tightening the drainage fitting 1, the watertight seal between the drainage port 4 and the bathtub 8 is brought into close contact with each other, so that water leakage from the bathtub 8 does not occur.

The drainage fitting 1 is configured so that a drainage plug 20 is in contact with the upper surface to make it watertight. A central opening 1a is opened at the center of the drainage fitting 1 for fitting the lift mechanism A, and an opening 1c is formed outside the central opening 1a except for a bridge 1e. Is provided,
The drain is configured to flow from the radial opening to the drain 4.

In a state where the drainage fitting 1 is fixed to the bathtub 8 and the drainage port 4, a lift mechanism A, which is an outer receptacle in which a wire 6 for remote operation is inserted, is connected to the drainage fitting 1. It is necessary to fix to the central opening 1a.
For this purpose, since the wire 6 for remote control is extended to the bottom side and passes through the outside of the bathtub 8 and is connected to the opening / closing operation unit 50, the lift mechanism A is drained from the inside of the bathtub 8. The lift mechanism A cannot be inserted into the central opening 1a of the metal fitting 1, but the bath tub 8 is always turned upside down, and the lift mechanism A is inserted from the bottom surface toward the central opening 1a of the drain metal fitting 1, and the bath tub is further inserted. The operation of fixing the upper surface of the lift mechanism A was performed from the inside of the bathtub 8 with the upper surface 8 facing upward.

In order to eliminate the trouble of turning the bathtub 8 upside down at the time of such assembling and repairing, a lift mechanism for a remotely operated drain plug is constructed as in the present invention. That is, in the drainage fitting 1 shown in FIGS. 2, 3, and 4, the lift mechanism A in which the wire 6 for remote control is inserted is first moved to the central opening 1 a of the drainage fitting 1. Must be inserted from below. Then, the lift mechanism A in which the wire 6 for remote operation is inserted is pushed through the central opening 1a to the inside of the bathtub 8, and in the pushed state, the drain plug 20 and the wire 6 for remote operation are pushed out. Concatenate.

Then, it is necessary to push the lift mechanism A again into the central opening 1a to fix the lift mechanism A and the wire 6 for remote operation so as not to go upward.
The fixing of the last lift mechanism A is conventionally performed by the lift mechanism A.
A screw is screwed into a screw hole on the upper surface of the drainage fitting 1 and fixed to the upper surface of the drainage fitting 1 with a screw.

It is configured such that it can be pulled out upward through the central opening and can be inserted again into the central opening by applying a downward insertion force.

[0018] Once pulled upward, the E-ring-shaped locking tool 3 and the hairpin-shaped locking tool 3 'are locked to the fixing portion 22 provided on the lift mechanism A, and from above. When it is pushed in, it is configured such that it cannot be pushed down from the E-ring-shaped locking tool 3 or the hairpin-shaped locking tool 3 '. In the embodiment of FIGS. 2 and 4, the fixing portion 22 is constituted by a locking groove. The E-ring-shaped locking tool 3 and the hairpin-shaped locking tool 3 'are engaged with the fixing portion 22 formed by the locking groove, and the E-ring-shaped locking tool 3 and the hairpin-shaped locking tool 3' are brought into contact with each other. In the hit state, the upwardly inclined surface 5a of the stopper locking portion 5 protrudes to the lower part of the central opening 1a. In this state, the lift mechanism A is engaged with and fixed to the central opening 1a. doing. Therefore, the central opening 1
a is formed at an angle so that the lift mechanism A does not come off upward with respect to the vertical movement of the remote control wire 6 inside the lift mechanism A, and the frictional force of the upwardly inclined surface 5a is remote. The frictional force is greater than the frictional force of the operation wire 6, and the lift mechanism A is configured not to come off.

Next, the embodiment shown in FIGS. 5 and 6 will be described. In this case, as shown in FIG. 7, without providing an engagement groove as the fixing portion 22 on the upper part of the lift mechanism A or providing the E-ring-shaped locking member 3 or the hairpin-shaped locking member 3 ′. An upper engaging projection 7 having a horizontal engaging surface 7a is arranged. The upper engaging projection 7 is provided on the upper part of the lift mechanism A, and can be inserted from the back side of the central opening 1a. After the insertion, the horizontal engaging surface 7 is brought into contact with the upper surface of the central opening and locked.
The upper engaging projection is provided with a. When the lift mechanism A is inserted from the back side, the upper engagement projection 7 is retracted by the horizontal engagement surface 7a, and the upper part first passes,
The lower portion of the lift mechanism A is also retracted by the upwardly inclined surface 5a, and passes through the stopper locking portion 5. But,
When the stopper is inserted from above, the stopper locking portion 5 passes through the central opening 1a by the downward inclined surface 5b, but the upper engaging projection 7 does not pass downward due to the horizontal engaging surface 7a. It is possible.

Next, the embodiment of FIG. 8 in which the fixing portion is constituted by the male screw portion 21 will be described. In this embodiment, an upwardly inclined surface 5a and a downwardly inclined surface 5b are provided below the lift mechanism A.
The same is the point that the stopper locking portion 5 provided with is provided, but a male screw portion 21 is provided as a fixed portion on the upper portion of the lift mechanism A, and a ring nut 19 is provided on the male screw portion 21. After the lift mechanism A has passed through the central opening 1a and exited to the upper part, the ring nut 19 is screwed in, and the pushing of the lift mechanism A is stopped at the position of the ring nut 19. .

Next, the embodiments shown in FIGS. 10, 11, 12, and 13 will be described. In this embodiment, a side slit portion 9 is opened at the central opening 1a of the drainage fitting 1. Therefore, the lift mechanism A is configured not to be inserted from the lower surface of the central opening 1a, but to be inserted and fixed from the side through the side slit portion 9.

However, if the lift mechanism A is simply inserted from the side slit portion 9, the lift mechanism A may easily come off the side slit portion 9 again.
Is inserted from above the bridging portion 1e provided in the opening 1c, and the upper part of the lift mechanism A is inserted into the insertion hole 18a provided in the retaining fitting 18 to temporarily The lift mechanism A inserted from the side slit portion 9 is configured to be flexible so that it does not fall out to the side. The lift mechanism A has a flange 23 and 24 projecting therefrom so as to prevent the lift mechanism A from being pulled up and down in a state of being inserted into the central opening 1a from the side slit portion 9 to constitute a vertical stopper. . The drain plug of the present invention may be formed by mixing a carrier having an antibacterial substance such as silver or copper supported on zeolite or the like with a resin of the material, and molding the mixture to be antibacterial.
