Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is applied to paint and FR.
It relates to an improvement of a brush for crushing a large number of small bubbles generated when P is applied.

[0002]

2. Description of the Related Art Also in a conventional brush, a brush portion, in which bristles are provided on the outer circumference of a coil portion formed of an elastic material in a coil shape, is rotatably coupled to a shaft provided on a handle. However, the brush part is flexible when used.
I couldn't transform into Le.

Since the conventional product has the above-mentioned structure, a brush having a small width must be used when coating a curved surface having a relatively small radius or crushing bubbles generated on the curved surface. In addition, in that case, the range in which the brush touched was significantly narrowed at one time, resulting in poor work efficiency. Furthermore, even if a brush having a small width is used, the bristles do not evenly come into contact with a curved surface having a small radius, which causes unevenness after coating or crushing bubbles. SUMMARY OF THE INVENTION It is an object of the present invention to eliminate such drawbacks of conventional products and to provide a brush in which the brush portion is flexibly deformed during use.

[0004]

Configuration of the present invention SUMMARY OF THE INVENTION comprises a brush portion that bristles on the outer periphery of the coil part formed in a coil shape is provided with a resilient material, bearing mounted at both ends of the brush portion And a handle for mounting the brush portion, the handle having an axis passing through the center of the brush portion.
And the shaft is attached to both ends of the brush part.
The brush part rotates around the shaft by being inserted into the shaft hole.
In a possible brush, sufficient play is provided between the shaft passing through the center of the brush part and the inner peripheral surface of the brush part , and
The coil parts are mutually
It is characterized in that a gap is provided so that it can be displaced .

[0005]

Embodiments of the present invention will now be described with reference to the drawings. The coil portion 1 formed in a coil is made of iron,
The bristles 2 are planted and provided over the entire length to form a brush portion 9. The coil portion 1 is wound so that there is a small gap between each adjacent winding portion of the coil portion 1.
Circular bearings 4 and 4 having flanges 3 are fitted to both ends of the coil portion 1 in a lid shape. The flange 3 is for covering the coil portion because the coil portion is exposed at both ends thereof. Shaft holes 5 and 5 are provided at the centers of the bearings 4 and 4. The inner diameters of the shaft holes 5 and 5 are such that there is a slight gap between the shaft holes 5 and 5 and the shaft 8 inserted therein.

The handle 6 is formed by attaching a steel bar, which is bent to form a shaft 8, to the tip of a wooden grip 7. By passing the shaft through the shaft holes 5 and 5 of the coil part 1, the brush part 9 and the handle 6 are coupled. The protrusions 10 and 10 provided at both ends of the shaft 8 are for preventing the brush portion 9 from moving left and right. In the case of this embodiment, the shaft 8 has a thickness of 0.5 cm, and the coil portion 1 has an inner diameter of 2.2 cm. Therefore, a relatively large play occurs between the shaft 8 penetrating the coil portion 1 and the inner peripheral surface of the coil portion 1, and the distance between them is 0.85c.
m.

FIG. 2 shows another embodiment of the handle in which an iron bar is bifurcated and shafts 11 and 11 are formed at the tip thereof. The shaft does not have to be a thick iron rod over the entire length, and the portion inserted into the shaft holes 5 and 5 to support the brush portion 9 must be a thick iron rod, but the middle portion thereof may be thin. Alternatively, the wire-12 may be used as in this embodiment.

[0008]

[Effect of the Invention A present invention the above-described configuration, Bed
Between the shaft 8 passing through the center of the brush portion 9 and the inner peripheral surface of the brush portion,
There is sufficient play and each adjacent carp of the brush part 9
So that the coil parts can be displaced between the
There is a gap. Therefore, the brush portion 9 is shown in FIG.
Since it can be flexibly deformed within the range of play as shown in,
When the paint is applied to the curved surface or the bubbles of FRP generated on the curved surface are crushed, the brush portion 9 is deformed along the curved surface, so that the work can be efficiently performed.
