Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a drainage device, and more particularly, to a drainage device in which a drain plug of a bathtub or the like can be attached and removed without getting one's hands wet.

(Prior Art) As a conventional drainage mechanism for bathtubs, etc., a drain plug made of flexible material such as rubber is provided at the drain port at the bottom of the bathtub, and the drain plug is connected to the bathtub by a chain of an appropriate length. This prevents forgetting.

(Problems to be solved by the invention) However, the conventional drainage mechanism described above has the following problems.

In order to attach or detach the drain plug, the user must reach to the bottom of the bathtub and take an awkward position. In addition, if there is water, you will have to wet your hands, and there is even a risk of falling into the water from an awkward position for the elderly and children.

The chain that connects the bathtub and the drain plug and its attachment part can be a nuisance during bathing or cleaning, and can sometimes cause injury.

Drain plugs and chains are difficult to clean, and since they are rarely washed, they can become hygienic due to the buildup of scales.

The chains caused countless thin scratches on the inner wall of the bathtub.
These scratches also contribute to the staining of the bathtub.

Furthermore, since the drain plug is located at the bottom of the bathtub, it is subject to considerable water pressure, making it difficult to remove, and when the drain plug is pulled out by pulling on the chain, the chain is likely to break.

(Means for Solving the Problems) In order to solve the above problems, the present invention has the following configuration.

That is, it has a drain plug that has magnetic force or magnetism and closes a drain port of a bathtub, etc., and a rod that is inserted so as to be able to move up and down inside a cylindrical body with both ends open, and has an opening at the lower end of the cylindrical body. A removal tool is provided on the edge or the lower end of the rod, which is made of a permanent magnet or a magnetic material, and has a suction part for magnetically attracting the drain plug, and when the drain plug is attracted to the suction part, the drain plug is removed. Fit the drain plug into the drain port, and press the drain plug into the drain opening with the lower end of one of the cylinders or rods that does not have a suction part in order to release the adsorption of the suction part while keeping the drain plug closed. It is characterized in that the suction part can be separated from the drain plug by manipulating the cylindrical body or rod having the suction part.

(effect) The operation will be explained with reference to FIG.

When the rod 22 of the extractor 10 is pulled up to the highest position and the suction part 30 approaches the top surface of the drain plug 12, the permanent magnet of the suction part 30 and the permanent magnet 34 arranged inside the drain plug 12 are attracted to each other. do. When the cylindrical body 14 is pulled upward, the drain plug 12 comes out from the drain port 38 while remaining adsorbed to the suction part 30.

Conversely, when pushing the drain plug 12 into the drain port 38, if the drain plug 12, which is still adsorbed to the suction part 30, is pushed into the drain port 38, the flexible covering material 3
2, the drain plug 12 fits into the drain port 38. At that time, when the cylindrical body 14 is pulled up, the lower surface of the retainer 28 separates the suction part 30 and the drain plug 12.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

First, the configuration will be explained.

In FIG. 1, 10 is a take-out tool, and 14 is a cylindrical body with both ends open. The upper part of the cylindrical body 14 is formed into a thick grip part 16 for easy grip. The through hole 18 bored in the center axis of the cylinder 14 is
The diameter of the upper part is larger than the diameter of the lower part with the seat surface 20 as a boundary.

22 is a rod, and the through hole 1 of the cylindrical body 14 is
It is inserted into 8.

The upper part of the rod 22 is formed into a handle 24. The rod 22 is arranged so as to be able to move forward and backward within the through hole 18. A step 26 is provided corresponding to the difference in the diameter of the through hole 18 to change the diameter, and the upper end of the rod 22 enters into the through hole 18. It prevents A thin plate is fixed to the lower end of the rod 22 as a stopper 28 to prevent the rod 22 from coming out of the through hole 18 when the rod 22 is pulled upward.

Reference numeral 30 denotes an attraction section, which is formed of a ring-shaped permanent magnet, and inside the ring is the cylindrical body 14.
The tip is fitted and fixed. The bottom surface of the suction section 30 is formed by cutting a portion corresponding to the retainer 28 by the thickness of the retainer 28 so that the lower surface of the suction section 30 becomes flat when the rod 22 moves to the uppermost position. .

Next, the drain plug will be explained.

The drain plug 12 is made of flexible rubber covering material 32
It is formed by embedding a permanent magnet 34 inside.

In the case of this embodiment, the magnetic poles of the mutually opposing surfaces of the attraction part 30 and the permanent magnet 34 of the drain plug 12, which are permanent magnets, need to be different magnetic poles.

Next, how to use it will be explained.

In FIG. 1, to pull out the drain plug 12 fitted into the drain port 38 provided at the bottom of the bathtub 36,
Hold the grip part 16 of the extractor 10 with one hand and press the suction part 3.
0 is brought close to the top surface of the drain plug 12. Then, the permanent magnet of the suction part 30 and the permanent magnet 34 of the drain plug 12 attract each other. Since the suction force at this time is sufficient, when the grip part 16 is pulled upward, the drain plug 1
2 exits from the drain port 38. At this time, take out tool 1
If the drain plug 12 is long enough, the drain plug 12 can be pulled out without getting your hands wet.

After being pulled out, the drain plug 12 can be stored together with the extraction tool 10 by adsorption to the suction part 30.

Next, when attaching the drain plug 12 to the drain port 38, the drain plug 12 is pushed into the drain port 38 while the drain plug 12 is attracted to the suction part 30. At this time, the drain plug 12 is surrounded by a rubber covering material 32, so that the drain port 38 is tightly closed.

Once the drain plug 12 is pushed in, the grip portion 16 of the cylinder 14 is pulled up while the rod 22 is fixed. Then, the suction part 30 and the drain plug 12 are separated, and the adsorption between them is released. At this point, if the take-out tool 10 is pulled upward, only the take-out tool 10 can be taken out from the bathtub.

Next, another embodiment will be described with reference to FIG.

The extractor 50 includes a grip portion 54 at the top of an outer cylinder 52, and an abutment portion 56 at the lower end.
The outer cylinder 52 and the contact portion 56 are connected through a through hole 58. An attraction part 60 is arranged inside the corresponding contact part 56, and a permanent magnet 66a is embedded therein. The plating plate 62 made of magnetic material is on the bottom surface that gets wet with water.
are arranged.

64 is a wire arranged as a rod,
The lower end is fixed to the suction part 60, and the upper end has a through hole 5.
A ring 68 having a diameter larger than 8 is fixed to prevent it from coming off.

Next, we will discuss how to use it.

First, when pulling out the drain plug 70, the suction part 60
is lowered to the lowest position, and holding the grip part 54, the suction part 60 is attracted to the upper surface of the drain plug 70.

The structure of the drain plug 70 is the same as that shown in FIG. 1, so a description thereof will be omitted.

When the suction part 60 and the drain plug 70 are attracted to each other, the drain plug 70 can be removed from the drain port 72 by holding the grip part 54 and pulling up the extractor 50.

Conversely, in order to attach the drain plug 70 to the drain port 72, the drain plug 70 is pushed into the drain port 72 while the drain plug 70 is adsorbed to the lower surface of the suction part 60. After confirming the insertion, the ring 68 is pulled upward along the elongated hole 74. Then, the drain plug 70 is prevented from rising by the lower edge of the contact portion 60, and the suction portion 60 and the drain plug 70 are separated. If the take-out tool 50 is lifted upward, only the take-out tool 50 can be taken out from the bathtub.

As an example of application, if a disk made of a magnetic material is attached to the lower end of the take-out tool, the take-out tool can be used as a spatula.

Various preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-mentioned embodiments. It goes without saying that many modifications can be made without departing from the spirit of the invention, such as not using the magnetic material, but using a magnetic material instead.

(Effect of the invention) By using the drainage device according to the invention, it becomes possible to attach and detach the drain plug in a comfortable posture without getting your hands wet.
Since there is no need for a chain on the drain plug, injuries and hygiene problems are eliminated, and damage to the bathtub can also be prevented.

Since the suction part covers the top surface of the drain plug, the water pressure applied to the drain plug itself is reduced, making it easier to remove the drain plug from the drain opening. Furthermore, since the attraction force of the magnet is utilized, it is possible to bring the extraction tool closer to the drain plug with great effect.
