Description

  The present invention relates to a brush that removes dust adhering to a surface to be cleaned and cleans it or cleans it.

  As a conventional brush of this type, a channel brush is formed by a band-shaped body and a brush piece that is bent at a substantially central portion and is sandwiched between the band-shaped body and the core wire, and the channel brush is formed into a rod-shaped core material. There are those formed by wrapping around the peripheral surface of the core material, and by forming a groove in the longitudinal direction of the peripheral surface of the core material and inserting a band-like body of the channel brush from the end of the groove (for example, Patent Literature 1).

  However, among the brushes described in Patent Document 1, the brush formed by winding the channel brush around the peripheral surface of the core material is long while rotating the core material after fixing one end of the channel brush to the core material. In this case, the channel brush strip is wound around the peripheral surface of the core material while being plastically deformed by the core material, but in this case, between the peripheral surface of the core material and the inner periphery of the strip member. It is necessary to control the rotation and movement of the core material and the channel brush so that the band-like bodies are kept at a constant interval while closely contacting so as not to generate a gap, which requires complicated work.

  Further, in the case of a brush formed by inserting a channel brush strip into a groove provided on the peripheral surface of the core material, it is necessary to provide a groove in the core material, and one end of the channel brush strip is connected to the core material. It has to be inserted and assembled from the end of the groove provided on the peripheral surface, and also in this case, complicated work is required.

  In order to solve the above problem, a brush as shown in FIG. 9 has been devised (see, for example, Patent Document 2).

  9A is a side view of a conventional brush described in Patent Document 2, FIG. 9B is a front view of the brush, and FIG. 9C is a side view of a brush showing another conventional example, (D) is a front view of the brush.

  9 (a) and 9 (b), a conventional brush is composed of a single base material 2 formed of a plastically deformable material and a linear material 3 having one end sandwiched between the base materials 2. The member 4 is formed, and both ends of the base material 2 are twisted in opposite directions. The twist center (TC) at this time is located at the center of the bottom surface of the base 2.

  Further, in the other conventional brushes shown in FIGS. 9C and 9D, the bottom surfaces of the base materials 2 of the two brush members 3 are brought together as shown in FIG. 9C. It is formed by twisting the center part of the attached part as the center (TC), and in any case, since no core material is required, the number of parts is small and man-hours such as providing a groove Is also unnecessary and is very easy to assemble.

  However, since the brushes described in Patent Document 2 are all twisted around the center of the bottom surface of the base material 2, the rotational outer diameter of the brush is very twice as high as the height h of the brush member 4. For example, even when trying to clean a small hole provided in a workpiece with a brush, the brush does not enter the hole, and there is a problem that the small hole cannot be cleaned or cleaned.

  Here, in order to reduce the rotating outer diameter of the brush, it is possible to reduce the height of the fibers and hairs constituting the linear material, but this reduces the contact area between the surface to be cleaned and the linear material. It is not preferable because the cleaning effect is lowered, and the fibers and hairs of the linear material are shortened to cause the fibers and hairs to become stiff and cause fine scratches on the surface to be cleaned.

  The present invention solves the above-described conventional problems, and while maintaining the conventional cleaning performance and cleaning performance by sufficiently securing the protrusion margin of the brush piece, the small holes are efficiently and reliably cleaned and cleaned. It aims to provide a brush that can.

  In order to solve the above-mentioned conventional problems, the brush of the present invention is composed of a belt-like body made of a plastically deformable member, and a brush piece having one end fixed to the belt-like body, and both ends in opposite directions. In a brush formed by twisting, the center of the twist is located within the cross section of the brush and between the bottom surface of the belt-like body and the approximate center of the tip of the brush piece. Therefore, it is possible to reduce the outer diameter of the rotation while ensuring sufficient protrusion margin of the brush piece and maintaining the necessary cleaning and cleaning performance, so that small holes can be efficiently and reliably cleaned and cleaned. Can be provided.

  The brush of the present invention is a brush formed of a band-shaped body made of a plastically deformable member and a brush piece having one end fixed to the band-shaped body, and twisted in opposite directions to each other. Since the center of the twist is located on the side of the belt-like body, the brush is formed in a substantially flat shape while maintaining the cleaning and cleaning performance by sufficiently securing the protrusion margin of the brush piece. The rotating outer diameter of the tube becomes smaller, and even a small hole can be efficiently and reliably cleaned and cleaned.

  The brush of the present invention can secure a sufficient protrusion margin of the brush piece and reduce the rotating outer diameter while maintaining the necessary cleaning and cleaning performance, so that a small hole can be efficiently and reliably cleaned. It can be cleaned.

  A first invention is a brush formed of a band-shaped body made of a plastically deformable member and a brush piece having one end fixed to the band-shaped body and twisted in opposite directions at both ends. The twist center is located within the cross section of the brush and between the bottom surface of the belt-like body and approximately the center of the tip of the brush piece. And since a rotation outer diameter can be made small, maintaining a required cleaning and washing | cleaning performance, a small hole can be provided efficiently, and the brush which can perform washing | cleaning and cleaning reliably can be provided.

  In particular, the second invention is formed by bending the brush piece of the first invention substantially at the center, and sandwiching the bent portion together with the core wire with a belt-like body so that the center of the core wire and the center of the twist are aligned. Therefore, the rotation accuracy of the brush can be improved, and the vibration and vibration when the brush is rotated can be greatly reduced.

  According to a third aspect of the present invention, there is provided a brush formed of a band-shaped body made of a plastically deformable member and a brush piece having one end fixed to the band-shaped body and twisted in opposite directions at both ends. Since the center of the twist is located on the side of the belt-like body, the brush is formed in a substantially flat shape while maintaining the cleaning and cleaning performance by sufficiently securing the protrusion margin of the brush piece. The rotating outer diameter of the tube becomes smaller, and even a small hole can be efficiently and reliably cleaned and cleaned.
