Abstract

PROBLEM TO BE SOLVED: To invariably keep the rim of a bicycle or the rim and spokes at the unstained state by fitting brushes to arms on both sides of a main body, fitting the main body to a mud-guard, and automatically polishing the rim of the bicycle from both sides. SOLUTION: Arms 2, 3 are curvedly protruded on both sides of a main body 1. One-side brushes 4, 5 are fitted to the arms 2, 3. The lower section of the main body 1 is stuck to the mud-guard of a bicycle by a double-sided tape. The main body 1 is fixed, and the one-side brushes 4, 5 fitted to the arms 2, 3 are invariably kept in contact with the rim of the bicycle. Stains of the rim are invariably wiped by the brushes 4, 5 when the bicycle is traveled, and no stains is fixed to the rim. The rim of the bicycle or the rim and spokes can be invariably kept at the unstained and bright state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for polishing a bicycle rim and a spoke.

[0002]

2. Description of the Related Art Conventionally, there is no method for automatically polishing the rims and spokes of the front and rear wheels of a bicycle, and the polishing is done manually by using a metal polisher or a brush. The rims of bicycles tend to get dirt and dust, and if left unpolished, they will rust. Therefore, it is necessary to polish it a little, but it is a laborious task, so the current situation is that it is not polished so much. However, it is desirable to be able to polish the rims and spokes automatically so that the bike will last longer and will always be in new condition.

[0003]

[Problems to be Solved by the Invention] Bicycle rims and spokes are very conspicuous points, and if these rims and spokes are kept in a constantly shining state, the bicycle will be evaluated as if it were a new product and the user will feel comfortable. Also, bicycles last longer. However, the conventional technique is troublesome because the bicycle rim and spokes have to be manually polished with a metal or brushed for a long time each time.

Therefore, the inventor of the present invention observes the structure of the bicycle and the state of adhesion of dirt, and can keep the rims and spokes as if they were new, so that dirt can fly to other things and stain other things. We paid attention to the point that an automatic stain removal device that does not exist could be created. However, the prior art does not consider automatically polishing the rim or the spokes at all, and thus requires the invention of a new technology. Once the dirt gets stuck,
It takes a lot of time to remove it, and an automatic machine for removing adhered dirt is expensive and impractical. Therefore, it is desirable to remove the dirt immediately when the dirt is attached. In this way, it is easy to install in order to attach equipment that does not stick dirt to the bicycle and polish the rim and spokes,
It should be lightweight, with no resistance to the rotation of the bicycle wheels.

[0005]

Means for Solving the Problems Claim 1 according to the present invention.
In the bicycle rim polisher described in 1), brushes 4 and 5 are attached to the arms 2 and 3 on both sides of the main body 1, and the main body 1 is attached to the mudguard. The double-sided tape 6 may be attached to the lower portion of the main body 1 to be attached to the front wheel mudguard or the rear wheel mudguard, or the mudguard may be sandwiched to fix the mudguard.
Arms 2 and 3 are curved inward and brushes 4 and 5 are attached to the tips.
Is attached, so that the brushes 4 and 5 lightly contact the rim. The degree of contact of the brushes 4 and 5 with the rim depending on the mounting height of the mudguard is changed by adjusting the bending condition of the arms 2 and 3.

In the bicycle rim polisher according to the second aspect of the present invention, the intermediate portion 22 and the tip portion 23 are attached to the body 20 having the hole 21, and the brush is attached to the intermediate portion 22 and the tip portion 23. By attaching 24, 25, the brushes 24, 25 come into contact with the rims and spokes while riding the bicycle and automatically remove dirt. Therefore, in order to mount the main body 20 on the frame of the bicycle, the main body 20
The holes 21 of the brushes are fitted into the hub, and the main body 20 is fixed to the frame of the bicycle with the clasp 27.
Can be held against the rim and spokes.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the bicycle rim polisher according to the present invention, as in the bicycle rim polisher according to claim 1, one bicycle rim polisher is used to simultaneously rim a bicycle rim from both sides of a wheel. Since the brushes 4 and 5 are in contact with each other, the lower portion of the main body 1 can be fixed by adhering it to a mudguard, and can be easily removed by using a double-sided tape as an adhering method. The shape of the bicycle with mudguards is almost constant, but there are some differences depending on the model, so to keep the brushes 4 and 5 lightly in contact with the rim,
This can be dealt with by manually adjusting the degree of bending attached to the arms 2 and 3. The dirt on the rim does not stick to the rim because it is always brushed off while riding the bicycle.

As a method of adhering the main body 1 to the mudguard of a bicycle, double-sided tape, a clasp, and a screwing can be considered.

A metal plate and a synthetic resin are suitable as the material of the main body 1, and the arms 2 and 3 are curved inward.

Brushes 4 and 5 are attached to the tips of the arms 2 and 3, and the brushes 4 and 5 are preferably made of nylon. The brushes 4 and 5 are fixed to the tips of the arms 2 and 3. However, in order to reduce the resistance to rotation of the bicycle wheels,
The brushes 4 and 5 may be formed in a ring shape so that the brushes 4 and 5 rotate about the arms 2 and 3.

It is difficult to polish simultaneously from both sides of the wheel with one bicycle rim polisher. In the method of polishing the rim and the spokes while riding the bicycle, one on the frame on each side of the wheel
It is necessary to install individual bicycle rim polishers. Then, like the bicycle rim polisher according to claim 2, the main body 2
To attach the 0 to the bicycle frame, fit the hole 21 of the body 20 into the hub and position it,
Brush 2 by sticking to the bicycle frame at 7
4, 25 could be held against the rim and spokes. The light contact of the brushes 24, 25 with the rims and spokes allows the rims and spokes to be polished with little resistance.

The body 20 is made of synthetic resin,
Metal and wood can also be used. The attachment part of the bicycle to the frame can be concave so that it can be fitted into the frame.

Since the size of the bicycle wheel is fixed, the main body 20 is prepared in accordance with each size. But,
The intermediate portion 22 can be used for adjusting the direction and size by connecting the main body 20 and the tip portion 23 with a wire or flexible tube made of a flexible material.

The brushes 24 and 25 are attached to the intermediate portion 2
2 and the tip portion 23 can be fixed, but in order to reduce resistance to rotation of the bicycle wheel, the brush 15,
It is also possible to make 16 a ring shape and to rotate about the intermediate portion 22 and the tip portion 23.

An embodiment will be described with reference to the drawings. FIG. 1 is a perspective view of a bicycle rim polishing tool according to claim 1. Arms 2 and 3 are curved on both sides of the main body 1. Brushes 4 and 5 on one side are attached to the arms 2 and 3. Body 1
Stick the bottom part to the mudguard of the bicycle with double-sided tape. Therefore, the body 1 is fixed, and the brushes 4 and 5 on one side attached to the arms 2 and 3 are always in contact with the rim of the bicycle.

FIG. 2 shows an example of use of the bicycle rim polisher according to the first aspect. The body 1 is adhered to the front wheel mudguard 7 of the bicycle with double-sided tape 6, and the brushes 4 and 5 on one side are in contact with the rim 8 of the bicycle. Brushes 4 and 5 on one side are lightly contacted with the roots of the rim 8 and the spokes 9 supporting the tire 10 to prevent dirt from adhering.
