Description

TECHNICAL FIELD The present invention relates to a brush such as a wire brush, and more specifically, to a brush capable of extending the life of the brush by preventing bristles from opening without deteriorating brush performance.

Brushes such as wire brushes are constructed by flocking bristles such as metal wires such as brass and stainless steel, and chemical fiber brushes such as polypropylene, polyester, and nylon on a base made of wood, resin, metal, or the like.

By brushing an object with a brush, dirt, paint, rust, etc., are removed, and metal surfaces, etc. are polished. As the brush is used, the bristles are worn out and open, and the brush bristles fall out, resulting in deterioration of brush performance such as dirt removal. In particular, when the object is heavily soiled, it is necessary to strongly rub the brush against the object when brushing, so the performance of the brush deteriorates quickly.

However, only the bristles come into contact with the object to remove dirt and the like. Therefore, a brush with short bristles was prepared and used. Furthermore, there is a risk that the base may come into contact with the object and cause damage.

SUMMARY OF THE INVENTION An object of the present invention is to provide a brush capable of extending the life of the brush by preventing the bristles from opening while maintaining brush performance.

In order to solve the above problems, the brush according to the present invention is
a base having a flocked surface;
brush bristles flocked to the flocked surface;
A brush comprising
a resin portion formed by embedding a flexible resin so as to surround the brush bristles from the flocking surface to a predetermined height of the brush bristles;
have

The resin can be a silicone resin.

The predetermined height may be 1/2 or more of the length of the bristles from the bristle-implanted surface.

The predetermined height may be the height up to the tips of the brush bristles.

The brush bristles may be made of metal.

According to the brush of the present invention, the bristles are embedded in the resin portion. As a result, even when the brush is rubbed against an object, the brush bristles do not open and can be maintained in a bundled state, thereby extending the life of the brush. In addition, the brush bristles are supported by the resin portion except for the tips, and the flexibility of the resin portion provides a certain amount of elasticity. There is no reduction in brush performance such as removal of shavings and polishing. Furthermore, even if a strong force is applied to knock down the bristles, the bristles supported by the resin portion will not fall down. Therefore, it is possible to perform brushing with a strong force, so that dirt and the like on the object can be preferably removed and polished, and the performance of the brush can be improved.

BEST MODE FOR CARRYING OUT THE INVENTION A brush according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1(a) is a perspective view of the tip of a typical brush 10 with a handle. The brush 10 with a handle is provided with a base 12 made of wood, resin, metal, or the like, at the tip of a grip 11 to be gripped by the user. have. A large number of holes are formed in the bristle-implanted surface 13, and bundled brush bristles 20 are inserted into the holes.

The brush bristles 20 can be exemplified by wires made of metal such as stainless steel or brass, chemical fiber brushes such as polypropylene, polyester, or nylon, and plant-derived fibers such as coconut. The base end side of the brush bristles 20 is flocked to the flocking surface 13 so that the heights of the bristles 21 at the tips are uniform.

As described above, a common brush can be used. In the following description, the handled wire brush 10 using metal wires as the brush bristles 20 will be described as an example.

The present invention is characterized in that brush bristles 20 are embedded in a resin portion 30 of the wire brush 10 shown in FIG. 1(a) as shown in FIG. 1(b). The resin portion 30 can be made of a flexible resin material such as silicone resin, epoxy resin, urethane resin, vinyl resin, or rubber. As shown in FIG. 1A, the resin part 30 is formed by placing a cylindrical mold 40 on the bristle-implanted surface 13 so as to surround the brush bristles 20, and filling the mold 40 with a melted or softened resin material. Then, it can be formed by curing and removing the formwork 40 . Alternatively, the resin portion 30 can be formed by immersing the brush bristles 20 in a melted or softened resin material up to the flocking surface 13 with the brush bristles 20 facing downward, and then lifting the brush bristles 20 to harden the resin material.

The resin portion 30 is formed so that the brush bristles 20 are embedded therein, as shown in FIG. 1(b). Preferably, the height of the resin portion 30 from the flocking surface 13 is 1/2 or more of the length of the brush bristles 20 . If the resin portion 30 is lower than this, the effect of providing the resin portion 30 may not be exhibited. Moreover, the maximum height of the resin portion 30 is a height at which the bristle tips 21 of the brush bristles 20 are completely embedded. Desirably, the resin portion 30 has a height such that 3 mm to 5 mm of the hair tip 21 is exposed from the resin portion 30 .

The wire brush 10 having the bristles 20 embedded in the resin portion 30 can rub the bristle tips 21 against an object, and the exposed tips can remove dirt and the like from the object and polish the object. If the hair tip 21 is embedded in the resin portion 30, the resin portion 30 may be removed to such an extent that the hair tip 21 can be visually recognized.

The brush bristles 20 are flexible, and the resin portion 30 in which the brush bristles 20 are embedded is also flexible. Therefore, since the brush bristles 20 themselves are flexible as a whole, they can exhibit a certain amount of elasticity when rubbed against an object. Therefore, there is no problem with the brush performance and the feeling of use of the wire brush 10 . The brush bristles 20 rub the surface of the object while being moderately bent to remove stains and polish the object. Since the brush bristles 20 are supported by the resin portion 30 except for the bristles 21, the force applied during brushing is hard to escape. In addition, even if a strong force is applied to knock down the brush bristles 20, since the bristles 20 are covered with the resin portion 30, the brush bristles 20 do not fall down, and the force is effective as a power for removing dirt and the like from an object and a power for polishing. acts on In this respect, as shown in the above problem, with a wire brush simply having short bristles, the bristles are not sufficiently flexible and hard, so there is a risk of scratching the object, etc. However, the wire brush of the present invention. 10 does not have such a problem because the bristles 20 remain flexible.

In addition, even if a strong force is applied to knock down the brush bristles 20, since the brush bristles 20 are supported by the resin part 30, the brush bristles 20 do not fall down, and the force can be used as a force to remove stains and the like from the object. It can act as an abrasive force. Therefore, it is possible to brush with a stronger force than a wire brush without the resin portion 30, and the brush performance can be improved.

Furthermore, since the brush bristles 20 are embedded in the resin portion 30 and integrated together, the brush bristles 20 do not open and the life of the wire brush 10 can be extended.

By continuing brushing, the bristles 21 of the brush bristles 20 are worn out, and the bristles may be hidden in the resin portion 30. - 特許庁As a result, the resin portion 30 rubs against the object, and as a result, the resin portion 30 is scraped and worn, and the bristle tips 21 are exposed from the bristles 20 . Therefore, the wire brush 10 can be used continuously as long as there is no problem that the resin portion 30 rubs against the object or that the resin portion 30 is abraded to produce dregs.

The wire brush 10 of the present invention can also form the resin portion 30 by post-processing a commercially available wire brush, and can exhibit the above effects.

The above description is for the purpose of illustrating the present invention and should not be construed as limiting the invention described in the claims or restricting the scope thereof. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and of course various modifications are possible within the technical scope described in the claims.

For example, as shown in FIG. 2, the present invention can also be applied to a wire brush 10A having an oval-shaped base 12A. In this case, as shown in FIG. 2A, a mold 40 may be placed on the bristle-implanted surface 13 of the base 12A so as to cover the outer periphery of the brush bristles 20, and filled with a resin material. Thereby, as shown in FIG. 2(b), an oval wire brush 10A in which the brush bristles 20 are embedded in the resin portion 30 can be obtained.
