However, when using a conventional painting roller brush to paint the inside of a C-shaped lip channel steel as shown in FIG.
In the conventional painting roller brush with a rotating brush, the arm part interfered with the lip part, resulting in unpainted areas.
These uncoated areas had to be repaired by recoating with a brush later.
Here, lip channel steel refers to a thin steel material with a C-shaped cross section, which is also called a C-channel.
It has a cross-sectional shape with a part called a "lip" that makes the cross-section look like a lip on the light channel steel.
Because it is lightweight, high-strength, and resistant to bending and bending, it is used in a variety of applications in the construction field, such as columns and beams in lightweight steel-framed buildings.
Many of the lip channel steels are surface-treated, and some are coated with red rust-preventive paint or hot-dip galvanized and white.
Some products are not surface-treated, such as black-skin products covered with an oxide film.
In that case, a coating finish or the like for rust prevention was required.

Therefore, the problem to be solved by the present invention is to provide a roller brush for painting used for painting lip channel steel, roofs, etc. is to provide

<Overall composition>
As shown in FIGS. 1 and 2, the roller brush 10 includes a grip portion 11, a cylindrical rotating brush 13, an arm portion 12 having one end fixed to the grip portion 11 and the other end to which the rotating brush 13 is attached, It has

<Grip part 11>
The grip part 11 is a part that an operator holds by hand when performing a coating operation using a roller. From the viewpoint of ease of handling, the grip part 11 is formed in a substantially square prism shape or a cylindrical shape with a wide center and an opening to the rear. A hollow portion is formed.
Materials for the grip portion 11 include synthetic resin, metal, and wood.

<Rotating brush 13>
FIG. 3 is a schematic illustration of a rotating brush used in the roller brush of the example.
As shown in FIG. 3, the rotating brush 13 includes a core portion 13a detachably attached to the arm portion 12, and a brush member 13b provided on the outer periphery of the core portion 13a.
The brush material 13b impregnated with paint can be applied by pressing the brush material 13b against the surface to be coated and rotating it.

<Brush material>
The brush material 13b is made of a cushioning material such as acrylic fiber, polyester fiber, or sponge, and can be impregnated with paint.
When the brush material 13b is made of a fiber material, the length of the bristles and the entanglement of the fibers are appropriately selected.

<Arm portion 12>
The arm portion 12 is made of a rod-shaped or pipe-shaped member, extends forward from the grip portion 11, and is bent midway up to a position where the rotary brush 13 is attached.
In the arm portion 12 of the embodiment, the base of the arm portion 12 is fixed to the front end of the grip portion 11, and is divided into four parts in the middle of extending forward.
That is, a first arm portion 12a extending forward from the front end portion of the grip portion 11;
A second arm portion 12b extending from the front end portion of the first arm portion 12a to the left front in a plan view at an angle X;
a third arm portion 12c extending from the front end portion of the second arm portion 12b to the right front in a plan view at an angle Y;
and a fourth arm portion 12d extending left forward at an angle Z in a plan view from the front end portion of the third arm portion 12c and having a rotating brush 13 attached thereto.
Here, the term “planar view” means that the plan views of FIGS. 1 and 2 are taken as a reference.

<First arm portion 12a>
The arm portion 12 is fixed to the grip portion 11 by press-fitting so that the rear end portion (base) of the first arm portion 12 a reaches the inside of the grip portion 11 .

<Second arm portion 12b>
The second arm portion 12b extends from the front end portion of the first arm portion 12a to the left front at an angle X in plan view.
Here, the angle X is the bending angle of the second arm portion 12b on the plane defined by the first arm portion 12a and the second arm portion 12b.

Angle X is preferably in the range of 1 degree to 10 degrees.
If it is less than 1 degree, the force in the vertical direction with which the rotating brush 13 is pressed against the coating surface becomes weak.
On the other hand, if it exceeds 10 degrees, the horizontal force against the coating surface for rotating the rotating brush 13 in the circumferential direction while being pressed against the coating surface is not stable in a desired direction, resulting in a poor finish of the coating surface. Become.

<Third arm portion 12c>
The third arm portion 12c extends from the front end portion of the second arm portion 12b to the right front at an angle Y in plan view.
The angle Y is preferably within the range of 2 degrees to 20 degrees.
If it is less than 2 degrees, the vertical force of pressing the rotating brush 13 against the coating surface will be weak,
If the angle exceeds 10 degrees, the horizontal force against the coating surface for rotating the rotating brush 13 in the circumferential direction while being pressed against the coating surface is not stabilized in a desired direction, resulting in poor finish of the coating surface.

<Fourth arm portion 12d>
The fourth arm portion 12d extends from the front end portion of the third arm portion 12c to the left front at an angle Z in plan view.
The rotating brush 13 is detachably attached to its tip.
The angle Z is preferably 90 degrees.

<Angle W: Angle between the axial direction 14 of the first arm and the axial direction 15 of the fourth arm>
As shown in FIG. 2, the axial direction 15 of the fourth arm portion 12d is
With respect to the axial direction 14 of the first arm portion 12a,
It is bent at an angle W that is an obtuse angle.
That is, the angle W is the angle between the axial direction 14 of the first arm and the axial direction 15 of the fourth arm.
Making the angle W obtuse is determined from the viewpoint of operability for inserting the rotating brush 13 into the lip groove 22 while avoiding interference with the lip 21 .
If the angle W is less than 90 degrees, it is likely to interfere with the lip 21.
If it exceeds 150 degrees, the fourth arm portion 12d to which the rotating brush 13 is attached opens too much,
The rotary brush 13 is less likely to come into contact with the painted surface of the inner surface of the lip channel steel 20. - 特許庁

The material of the arm portion 12 is preferably a metal round bar or pipe from the viewpoint of strength, but is not limited to this.

FIG. 5 is a schematic explanatory view showing a mode of use of coating the inside of the lip channel steel 20 using the roller brush 10 of Example 1. FIG.
As shown in FIG. 5, the arm portion does not interfere with the lip 21, the inner surface is not left unpainted, and there is no need to repaint and repair with a brush later.

The roller brush 10 of the embodiment can be used not only for coating the inner surface of the lip channel steel 20, but also for coating the seam 30 on the top of the roof as shown in FIG.
For example, the operator impregnates the roller brush 10 with paint,
By applying a vertical force to the seam portion 30, keeping the roller brush 10 pressed against the seam portion 30, applying a horizontal force to the seam portion 30, and rotating the roller brush 10 in the circumferential direction. , seam 30 can be painted.
At this time, even when the grip portion 2 and the seam portion 30 are positioned substantially parallel,
Since the angle W is an obtuse angle with respect to the grip portion 12,
Workers can work safely.

In addition, as shown in FIG. 7, the roller brush 10 of another embodiment can also be provided with an angle adjusting means 12e having a rotating portion in the middle of the second arm portion 12b.
Accordingly, paint adheres to the rotating portion of the angle adjusting means 12e when the angle adjusting means 12e is provided in the middle of the second arm portion 12b rather than when the angle adjusting means 12e is provided in the third arm portion 12c or the fourth arm portion 12d. Therefore, the angle adjusting operation of the roller brush 10 is facilitated.
In other words, the degree of freedom in the bending angle of the arm is increased, the arm can be prevented from interfering with the object to be coated, leaving no coating uncoated, and even the inner details of the lip channel steel can be coated.
