Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a drain pipe cleaning method used to remove debris clogged in drainage pipes such as washstands and kitchen sinks, sewer pipes, rain gutters, etc. It's about the ingredients.

(b) Conventional technology This type of conventional drain pipe cleaning tool was first applied in 1973.
There is one described in No. 167117.

That is, as shown in FIG. 4, a relatively long flexible member 21 having a coil-shaped hook 22 at the tip is connected to the rotary container 23 via a cylindrical rotating shaft portion 24 connected to the lower part of the rotating container 23. While being inserted and stored in the container 23, the rotating shaft portion 24 is provided with a fixing member 28 for the flexible material 21, and the container 2
3, an operating part 25 and a protrusion 27 are protruded at symmetrical positions that are eccentric from the shaft part 24, and a nail hole 26 is provided in the projection 27.
The rotation support cylinder 29 is fitted around the support cylinder 2.
The rotary container 23 is configured to be able to be rotated by the operating section 25 about the rotating shaft section 24 of No. 9 as an axis.

(c) Problems to be solved by the invention Conventional drain pipe cleaning tools have the following drawbacks.

That is, in the conventional example shown in FIG. 4, when the flexible material 21 (so-called wire) is inserted into the rotating container 23 from below the rotating shaft portion 24, the flexible material 21 is approximately 8mm wide as shown in the figure. This flexible material 21 is bent into a letter shape.
The same flexible material 21 has a bending habit.
There was a drawback that the rotary container 23 could not be accommodated smoothly in the rotary container 23.

(d) Means for solving the problems Therefore, the technical problem of the present invention is to provide a drain pipe cleaning tool that can smoothly store flexible materials in a rotating container.

The technical means of the present invention to solve this technical problem is that, in the above-mentioned drain pipe cleaning tool, a drum support shaft is provided in the center of the rotary container, which faces from the center of the back surface to the center of the front surface of the container; A winding drum that rotates around the drum support shaft is rotatably inserted into the rotating container through a round hole bored in the center of one main surface of the container, and a lid portion of the winding drum outside the container is inserted. While the operation knob is integrally formed on the
The base end of the flexible material is locked to the winding drum.

(E) Function According to this technical means, when the winding drum is rotated in a predetermined direction using the operating knob, the flexible material is sequentially wound around the outer periphery of the winding drum. This allows the flexible material to be smoothly stored one after another without being bent in a substantially figure-eight shape within the container.

(f) Embodiment An embodiment of the present invention will be described below in detail based on the drawings.

In FIG. 1, reference numeral 1 denotes a flexible member made of a coil spring having a length of 3 to 5 meters, and the flexible member 1 is stored sequentially along the outer periphery of a winding drum, which will be described later. 2 is a coil-shaped hook connected to the tip 1a of the flexible material 1 via a connector 10; 3 is a rotating container made of synthetic resin;
The rotating container 3 is provided with a cylindrical rotating shaft portion 4 below,
Further, a protrusion 7 having an operation part 5 eccentric from the shaft part 4 and a nail hole 6 is provided upwardly in a bulging shape, and a flexible material fixing member 8 such as a thumb screw is provided at the lower part of the rotary shaft part 4. A rotation support tube 9 made of synthetic resin is fitted around the rotation shaft portion 4.

Here, the connector 10 consists of an upper metal fitting 10a and a lower metal fitting 10b.
a and 10b are provided so as to be bendable with pins (not shown).

Therefore, unlike bending by only the flexible material 1, the one metal fitting 10b is bent by the other metal fitting 1.
Since the flexible member 1 is bent at a right angle or an acute angle with respect to 0a, the hook 2 at the tip of the flexible member 1 can be inserted more smoothly into the bent portion of the pipe.

At the center of the rotating container 3, as shown in FIGS.
A drum support shaft 11 facing toward the center is provided.

As shown in FIG. 3, this drum support shaft 11 is a stepped bolt consisting of a head, a shaft, and a threaded part. form, washers 12,1
By screwing the nut 13 into the threaded portion of the drum support shaft 11 with the drum support shaft 1 interposed therebetween, the drum support shaft 1
1 is attached to a rotating container 3.

Further, a relatively large diameter round hole 14 is bored in the center of the front surface 3b of the rotary container 3, and a winding drum 15 made of synthetic resin is housed inside the rotary container 3 through this round hole 14. ing.

This winding drum 15 rotates around the drum support shaft 11, and its specific configuration is as follows.

That is, a cylindrical portion 17 formed around a hole 16 through which the drum support shaft 11 passes, a cylindrical drum portion 18 around which the flexible material 1 is wound, and both 17 and 18 are integrally connected. This winding drum 1
Operation knobs 20, 20 are located on the lid 19 outside the container 3 in No. 5.
It is integrally formed.

Then, the base end 1b of the flexible material 1 is
The winding drum 1 is attached using a locking device 21 such as a ring.
It is locked to the drum part 18 of No. 5.

The illustrated embodiment is configured as described above,
The action will be explained below.

When using this drain pipe cleaning tool, the flexible material 1 is pulled out a predetermined length from the container 3 with the hook 2 positioned downward, and the flexible material 1 is attached to the lower shaft of the container 3 using the fixing member 8. Fixed within 4.

After that, for example, insert the hook 2 and the flexible material 1 from above the drain pipe of the wash basin, and fix the flexible material 1 within the shaft portion 4 at the bottom of the container 3 using the fixing member (wing bolt) 8 as described above. , by supporting the rotary support tube 9 with one hand, holding the operating section 5 with the other hand, and rotating the operating section 5 around the rotating shaft section 4 fitted into the rotation support tube 9, the drainage pipe can be opened. Even at the bent part, the hook 2 and the flexible material 1 can easily move in a meandering manner due to the bending of the connecting tool 10 and the inherent flexibility of the flexible material 1, and can easily move against dirt stuck in deep parts. The coiled hook 2 is entangled in a spiral shape,
By pulling out the flexible material 1, the garbage is removed from the drain pipe.

In order to store the pulled out flexible material 1 in the rotary container 3 after the dust removal work is completed, the winding drum 15 is rotated clockwise in FIG. 1 using the operating knobs 20, 20. be.

When the drum 15 is rotated in the same direction, the flexible material 1 is sequentially wound around the outer periphery of the drum portion 18 of the winding drum 15 since its base end 1b is locked to the drum 15.

Therefore, the flexible material 1 is no longer bent in an approximately figure-eight shape inside the container 3 as in the past, and the flexible material 1 is not folded into the winding drum 15.
As it rotates, it is wound smoothly around the outer periphery of the drum 15 one after another.

(g) Effect of the idea The unique effects of the present invention are as follows.

That is, the flexible material 1 is not stored by being pushed in from one direction as in the past, but is wound around the outer periphery of the winding drum 15 one after another by rotating the drum 15. This has the effect of being able to be wound smoothly around the outer periphery of the winding drum 15 without causing any undesired bending within the container 3.

Furthermore, since the flexible material 1 does not have the same bending tendency as in the conventional case, it is of course possible to store the flexible material 1 smoothly at all times.
