Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a channel brush used as a roll brush for polishing or cleaning.

BACKGROUND ART AND PROBLEMS A channel brush is made by holding the base of a brush material in a substantially U-shaped channel, which is wound around a roll to form a roll brush.

However, when this channel brush is formed into a roll brush, a continuous line with a sparse brush material density is formed between the windings of each channel, resulting in vertical striped polishing or cleaning spots, and local hair removal may cause other damage. The disadvantage is that it may spread to other areas and cause so-called continuous hair loss.

Conventionally, wedge-shaped claw pieces with the width in the longitudinal direction of the channel are extended from the left and right edges of the U-shaped channel, the wedge-shaped claw pieces are inserted into the brush material, and the brush material is narrowed between the adjacent wedge-shaped claw pieces. There is a known structure in which it is divided into bundles and supported (see Utility Model Publication No. 61 of 1973). This idea was aimed at increasing the strength of the brush material by dividing and supporting the brush material between each wedge-shaped claw piece. In addition to the disadvantage that the brush material cannot withstand the lateral pressure caused by excessive tightening and easily deforms and loses its support function, the core brush material is pushed into the gap between the sharp toes and is constantly rubbed. Due to the vibrations, the sharp toes act as blades, cutting the brush material and causing continuous hair removal.

In addition, the above-mentioned conventional device does not intend the effect of applying a trapping pressure to the waist of the brush material, but the intervention of the tip of the toe from the edge of the channel has an escape effect of the brush material between the wedge-shaped claw pieces (the waist of the brush material is applied to the trapping pressure). In particular, the wedge-shaped claw pieces have a width in the longitudinal direction of the channel and are inserted into the brush material, so it is difficult to distinguish between wedge-shaped claw pieces. This method has a major disadvantage in that an excessively large gap is created between the brush material bundles.

Purpose of the invention The present invention aims to eliminate the above-mentioned drawbacks and effectively solve the problem of continuous hair removal and polishing spots that are problems of channel brushes without forming large gaps between small bundles of brush material. be.

Means and Effects for Solving the Problems The present invention provides the channel brush as a means for solving the problems described above, by cutting out the side plate of the U-shaped channel and attaching a brush holding piece of width from the channel mouth edge toward the bottom. The brush material is cut and bent toward the inside of the channel and inserted into the brush material in the width direction, and the brush material is divided by the thickness of the holding piece. In this way, the waist portion of the brush material is sufficiently bulged outward from the larger concave notch formed by cutting each holding piece, while ensuring the capture of the brush bundle without creating a harmful large gap. In addition to ensuring that adjacent brush members are in close contact with each other, the brush members are reliably captured between the holding pieces to effectively prevent continuous hair removal.

Examples of ideas Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is a channel brush, 2 is a U-shaped channel made of a metal strip constituting the channel brush, and 3 is a brush material.

As is known, the brush material 3 is folded in two, a core wire 4 is inserted into the inside of the folded portion, and the base of the brush material through which the core wire 4 is inserted is sandwiched and held within the U-shaped channel 2 to form the channel brush 1. do.

In the channel brush 1, the left and right side plates 2a, 2b of the U-shaped channel 2 are cut and raised to form a large number of brush holding pieces 5, 6 having a width extending from the channel mouth edge toward the bottom.

The left brush holding piece 5 and the right brush holding piece 6 are equally spaced from each other in the longitudinal direction of the channel, and are arranged in the same phase or out of phase.

The left side brush holding piece 5 and the right side brush holding piece 6
is bent inward of the channel 2, and inserted into the brush material 3 by the width of the plate from the channel mouth edge toward the bottom. With the intervention of the holding pieces 5 and 6, the brush material 3 is divided into small bundles by the plate thickness of the brush material holding pieces, and the sides of the divided brush bundles are supported by the width sides of the holding pieces 5 and 6.

By cutting and bending the brush holding pieces 5 and 6, a brush relief recess 9 is formed on the channel side plates 2a and 2b.
Define 10. Reference numeral 13 indicates a bulging portion of the brush material pushed out from the recessed portions 9 and 10 toward the outside of the channel.

The brush holding pieces 5 and 6 are rectangular as shown, but may be trapezoidal depending on the implementation. It can also be triangular or arcuate.

As shown in FIGS. 1 to 3 and 4, the brush holding pieces 5, 6 and brush escape recesses 9, 10 are arranged in the channel longitudinal direction on one channel side plate 2a and the other side plate 2b. They can be arranged alternately with a phase shift.

Further, FIGS. 6 and 7 show a case where the brush holding pieces 5, 6 and the brush relief recesses 9, 10 are arranged in the same phase and at equal intervals in the longitudinal direction of the channel.

As another example, as shown in FIG. 5, the holding pieces 5 and 6 are bent at different phases in the channel longitudinal direction on one channel side plate 2a and the other channel side plate 2b, and the recessed parts 9 and 10 are bent in the same phase. Correspond so that

Further, the brush holding pieces 5, 6 are constituted by a single piece extending from one side of the channel side plates 2a, 2b to the other, as shown in FIGS. 1 to 3 and 5, for example. In this case, the tips of the brush holding pieces 5 and 6 are brought into contact with or close to the other channel side plate, and inserted into the brush material 3 over substantially the entire width between the channel side plates.

The difference between FIGS. 1 to 3 and FIGS. 5 and 4 is that the spacing between the brush holding pieces 5 and 6 in the channel longitudinal direction and the opening widths of the recesses 9 and 10 in the channel longitudinal direction are approximately the same in the former. In the latter case, the distance between the brush holding pieces 5 and 6 is increased and the opening width of the recessed portions 9 and 10 is decreased.

As another example, as shown in FIG. 6, the brush holding piece 5 bent and inserted from one channel side plate 2a and the brush holding piece 6 bent and intervened from the other channel side plate 2b are placed in a facing state, or
Alternatively, they may be placed in an overlapping state and inserted into the brush material 3 to capture the brush material.

Effects of the invention According to the invention, by intervening the holding piece into the brush material, the intervening gap of the holding piece can be limited to the thickness of the holding piece, and therefore, a harmful large gap is created between the divided brush bundles. The above-mentioned intervention and capture into the brush material can be accomplished without any interference, and at the same time, a larger recessed part is created by cutting and raising the holding piece, and a part of the brush bundle can be reliably moved outward from the recessed part. By extruding, a brush bulge is created more prominently than before, and when a channel brush is wound on a roll, the closeness with adjacent brush material is increased, and a continuous line with sparse brush density between windings is created. Eliminate.

In addition, since the holding piece captures the brush material while being in contact with the side surface of the board width, it effectively prevents hair breakage that occurs when the brush material is captured on the conventional board thickness surface, and prevents hair loss at extreme areas due to cut hairs, Continuous hair loss phenomenon caused by partial hair loss can be more effectively prevented.

As described above, this invention effectively solves the problem of continuous hair removal by dividing the brush material implanted in the channel into small sections and capturing it properly, and also encourages the escape of the brush material to the outside of the channel for polishing and cleaning. This also accurately solves the problem of the occurrence of spots.
