[0011]

EXAMPLES The present invention will be described in detail below with reference to examples. The drain plug 1 is formed in a cylindrical shape that opens up and down, and an upper locking piece 21 is projected on the outer periphery of the upper end opening, and a lower locking piece is provided on the entire circumference of the drain plug 1 substantially in the center. 22 is provided. A male screw (not shown) is formed at the lower end of the drain plug 1.
The kelep body 2a has a disk shape and is formed to have substantially the same size as the upper end opening of the drain plug 1, and the kelep body 2a.
and a connecting rod 14 protruding downward from a substantially central portion of the lower surface of a. Then, the connecting rod 14 can be inserted from the upper end opening of the drain plug 1 to attach the kelep 2 to the drain plug 1 so as to be vertically movable. A hair catcher 23 for removing hair and dust is fitted inside the drain plug 1.

As shown in FIG. 2, the release 3 is formed by inserting a metallic inner cable 4 into an outer casing 12 having a tubular shape. The outer casing 12 is formed of a bendable resin, and by forming the outer casing 12 of resin in this way, the release 3 can be manufactured at a lower cost than when using the metal outer casing 12.

A rod 5 formed of a metal cylindrical rod or the like is attached to one end of the inner cable 4 of the release 3. An operation tool 6 is connected to the other end of the inner cable 4. The operation tool 6 is, for example, a ball 19
It is vertically movably fitted to the main body cylinder 17 which is attached to the peripheral edge of the upper surface opening with a nut 31, and a knob portion 18 is provided at the upper end thereof. Then, the end of the outer casing 12 of the release 3 is fixed to the lower end of the main body cylinder 17 protruding to the back surface of the ball 19 with the nut 24 via the washer 32, and the end of the inner cable 4 is connected to the lower end of the operation tool 6. To do so. The operation tool 6 and the inner cable 4 are connected to each other, for example, by a notch 6a provided at the lower end of the operation tool 6 and a connector 4a provided at the tip of the inner cable 4.
It is possible to connect the operation tool 6 and the inner cable 4 easily by fitting.

The drain pipe 7 is formed by providing an internal thread 30 on the inner peripheral surface of the upper end opening connected to the drain plug 1 and providing a bent portion 8 on the upper portion thereof. The bent portion 8 can be formed by bending a straight pipe by a known method. As another method, an opening portion is provided on a side surface of a bottomed pipe whose upper surface is opened, and the opening portion is separated. The upper opening of the pipe may be connected. By providing such a bent portion 8 on the drainage pipe 7, a mounting portion 9 is formed immediately below the upper end opening of the drainage pipe 7. The mounting portion 9 can be formed on a horizontal surface, for example.

The rod holder 10 has a tubular portion 10a having a through hole 11 penetrating vertically, a waterproof cover 10b attached to the outer periphery of the upper end opening of the through hole 11 via a waterproof O-ring 26, and a tubular member. It is formed by a screw portion 10c provided at the lower end of the portion 10a, and the cylindrical portion 10a and the screw portion 1 are formed.
A flange portion 10d is provided on the outer peripheral surface of the boundary of 0c.

Next, a process of assembling a drainage device using the above members will be described. First, an opening 27 is formed on the bottom surface of the ball 19, the drain plug 1 is inserted into the opening 27, and the ball 1 is formed by the upper locking piece 21 and the lower locking piece 22 of the drain plug 1.
The bottom of 9 is clamped and the drain plug 1 is attached. At this time, a waterproof material 28 is provided between the upper locking piece 21 and the inner peripheral surface of the opening 27. Next, drain pipe 7, release 3, rod 5
And so on. As shown in FIG. 3A, the connecting method is such that the mounting portion 9 has a mounting hole 2 that opens inside and outside the drainage pipe 7.
5 is drilled and the screw portion 10c of the rod holder 10 is formed.
The rod holder 10 as shown in FIG.
The rod 5 provided at the tip of the release 3 is vertically movably inserted from the lower end opening of the rod 3 so that the upper end of the rod 5 protrudes from the upper end opening of the rod holder 10 and is inserted into the release 3 in advance as shown in FIG. Preserved nut 28 and screw part 1
0c is screwed through a washer 32, and the flange portion 10d of the rod holder 10 and the nut 28 are attached to the mounting hole 25.
It can be carried out by sandwiching the drainage pipe 7 around the periphery thereof, and can be attached as shown in FIG. At this time, the rod 5 inserted into the rod holder 10
Is located directly below the connecting rod 14 of the kerep 2. In FIG. 1, 29 is a waterproof packing on the lower surface of the flange portion 10d. Then, a male rod provided at the lower end of the drain plug 1 and an female screw at the upper end of the drain pipe 7 are screwed to be coupled with each other, and the upper end of the rod 5 is projectingly provided on the lower surface of the kelep 2.
The drainage device as shown in FIG. 1 is formed by bringing it into contact with the lower surface of 4.

In the above drainage device, when the operating tool 6 is pushed down, the force is transmitted to the rod 5 through the inner cable 4 of the release 3 and the rod 5 moves upward, and the rod 5 moves upward. By Kelep 2 connecting rod 1
Push up 4 and push up Kelep 2 upwards,
The water in the ball 19 can be drained by opening the upper end opening of the. Further, the operation tool 6 is pulled up to move the rod 5 downward through the inner cable 4 of the release 3, and the downward movement of the rod 5 causes the kelep 2 to move.
Is dropped by its own weight and the upper end opening of the drain plug 1 is closed, so that water can be stored in the ball 19.

Then, the drainage pipe 7 is bent and the kerep 2 is formed.
The mounting portion 9 is formed immediately below the rod holder 10, the rod holder 10 is disposed on the mounting portion 9, and the drain pipe 7 is attached to the rod holder 10.
Since a vertical through hole 11 opening inward and outward is formed and the rod 5 is inserted into the through hole 11 so as to be vertically movable, the rod 5 is inserted straight into the through hole 11 from the outside of the drain pipe 7 and the rod holder. It can be inserted into the drainage pipe 10, and there is no need to change the direction in the drainage pipe 7. Further, it suffices to insert the rod 5 straightly, and the rod 5 can be easily inserted even if the through hole 11 has a small hole diameter.

[0019]

As described above, according to the present invention, the drainage pipe connected to the lower end of the drainage plug is bent to form a mounting portion located directly below the kelep at the bending portion of the drainage pipe, and the rod is attached to the mounting portion. A vertical hole is formed in the rod holder that is located inside and outside the drainage pipe and is located directly under the kelep while the holder is installed.The rod is inserted through this hole so that it can move up and down. It can be inserted into the rod holder by inserting it from the outside of the drain pipe, there is no need to change the direction inside the drain pipe, and it is easy to visually check the through hole from the outside of the drain pipe. However, the rod can be easily inserted and attached, the number of working steps can be reduced, and the working time can be shortened.

Since the outer casing of the release is made of resin and the inner cable is made of metal,
The release can be formed at a lower cost than when the outer casing is made of metal.
