[0010]

1 to 3 show an embodiment of the present invention. FIG. 1 is an assembly view of the coating roller body D, FIG. 2 is a view when the coating roller body D is attached to a pressure feeding device, and FIG. It is. As shown in FIG. 1, the coating roller main body D includes a mounting member 15 to which the rods 13 and 14 are fixed, and a flow pipe 16 rotatably connected to the mounting member 15. The attachment member 15 and the flow pipe 16 are provided with screws (not shown) so that rotation thereof can be restricted.

Further, the two rods 13 and 14 are fixed to a mounting member 15 so as to be parallel. The brush members 20, 21 are attached to the rods 13, 14 so as to cover the outer circumferences thereof.
That is, the brush members 20 and 21 have rods 13 and 1 attached thereto.
The core members 20a and 21a having substantially the same inner diameter as the outer diameter of the rods 4 are formed, and the core members 20a and 21a are inserted into the rods 13 and 14, respectively. I have to.

The flow pipe 16 includes a first pipe part 16a connected to the mounting member 15, a third pipe part 16c connected to a grip 19 described later, and a first pipe part 16a and a third pipe part 16c. And a second pipe portion 16b located therebetween. The second tube portion 16b is formed so as to be substantially parallel to the rods 13 and 14, and the third tube portion 16c is formed so as to be substantially perpendicular to the rods 13 and 14. I have.

The third pipe portion 16c is formed such that its extension is located substantially at the center of the rods 13 and 14. Further, a tubular ejection portion 17 is formed at a connection portion between the third tube portion 16c and the second tube portion 16b and on an extension of the third tube portion 16c. Furthermore, this spout 1
7, a spout 17a is provided at the tip of the spout 17a.
The paint is spouted from

As described above, the ejection portion 17 is connected to the third tube portion 16c.
And the third pipe portion 16c is located substantially at the center of the rods 13 and 14, so that the jetting portion 17 is located substantially at the center of the rods 13 and 14. Therefore, the paint ejected from the ejection port 17 a of the ejection section 17 is ejected near the center of the rods 13 and 14. The mounting member 15 in which the ejection hole 17 is formed is rotatably connected to the flow pipe 16, and thus the two brush members 20 and 21 are rotatably connected to the painted surface. It comes into close contact.

Further, when the brush members 20, 21 are brought into contact with the painted surface, the mounting member 15 is prevented from coming into contact with the painted surface. If the mounting member 15 hits the painted surface, the brush members 20, 21 will not come into contact with the painted surface. If the brush members 20 and 21 do not exactly contact the paint surface, the paint will be uneven. For this reason, the mounting member 15 is
At the time of painting, it does not hit the painted surface.

The flow pipe 16 is connected to a grip 19, and a lever 22 is provided on the grip 19. By gripping the lever 22, the paint is guided to the flow pipe 16 side. Further, a flow control throttle 18 is provided above the grip 19. The flow control throttle 18 adjusts the flow rate of the paint supplied to the flow pipe 16. For example, when the painted surface is wide, the painting can be performed efficiently by increasing the flow rate, and when the painted surface is narrow, the flow rate can be decreased. By reducing the flow rate in this way, it is possible to prevent the paint from protruding from the painted surface. Therefore, the paint does not protrude from the painted surface, and a clean paint can be obtained.

As shown in FIG. 2, this coating roller main body D is attached to a pressure feeding device. As shown, the lower end of the grip 19 is connected to a paint supply hose 23, and a tank 24 is connected via the paint supply hose 23. The tank 24 stores paint. A pressure control valve 25 is provided at a connection portion of the tank 24 for the paint supply hose 23 so that the supply pressure of the paint can be adjusted by the pressure control valve 25. In addition, the tank 2
4 is connected to a compressor 27 via an air pipe 26 so that the air compressed by the compressor 27 is sent to the tank 24.

Next, the operation of this embodiment will be described. When the lever 22 provided on the grip 19 is gripped, the paint is supplied from the paint supply hose 23 to the distribution pipe 16 by air pressure. The paint supplied to the circulation pipe 16 is ejected from the ejection port 17a toward the two brush members 20, 21 via the third circulation pipe 16c by the pressure. The paint is ejected near the center of the brush members 20 and 21, and the ejected paint easily spreads over the entire brush members 20 and 21. When the paint spreads over the entire brush material 20, 21,
Not only can a wide area be painted at a time, but also the finish can be uniform.

While the paint is being sprayed on the painted surface as described above, the paint roller body D is moved by pulling the paint roller body D toward the user or pushing it toward the other side. At this time, as shown in FIG.
The brush members 20 and 21 are rotated. By rotating the mounting member 15 in this manner, both the brush members 20, 21 can be adhered to the painted surface exactly. When the attachment member 15 is rotated as shown in FIG. 3, the paint can be ejected from the ejection port 17a between the brush members 20 and 21. By spraying the paint between the brush members 20 and 21 in this manner, it is possible to reduce the amount of the paint scattered outside the brush members 20 and 21.

When the coating roller body D is pulled forward, the paint can be evenly distributed by one of the brush members 20, and when the coating roller body D is pushed away, the other brush member can be used. 21 allows the paint to be evenly leveled. That is, in this embodiment in which the brush members 20 and 21 are provided on both sides of the ejection hole 17, the paint can be leveled even if the coating roller main body D is moved to the near side or the far side. Further, even when the coating roller body D is reciprocated several times to achieve a more beautiful coating, the coating can be performed more efficiently than when there is only one brush member.

The ejection section 17 is provided with a third pipe section 16c.
Of the brush member 2, i.e., the brush member 2
Since it is provided between the grips 0 and 21 and the grip, this spraying portion 17 does not interfere with the coating. In particular, even when, for example, an attempt is made to paint around a corner formed by a wall and a ceiling, the ejection portion 17 does not interfere. Therefore, work efficiency is improved, and uneven coating and the like are reduced.

In the first embodiment, the work efficiency can be improved as follows by making the brush members 20, 21 different in thickness or using different materials. That is, for example, if one is a brush member suitable for smoothing the paint, and the other is a brush member suitable for finishing the smoothed paint, the finishing can be performed only by rolling the coating roller once.

Although two rods are used, three or more rods may be used. FIG. 4 shows the positions of the brush members when three brushes are attached to these rods. FIG. 4A shows a state in which three rods are fixed to the attachment member 28 in a straight line, and the brush member R is attached to these rods.

Further, as shown in FIG.
When three R2 and R3 are arranged in a triangle, the surface A is formed by the brush members R1 and R2, the surface B is formed by the brush members R2 and R3, and the surface C is formed by the brush members R3 and R4. . At this time, for example, by using different types of brush members R, the surface to be used can be changed according to the application. That is, the paint is spread to other parts on the face A, the paint spread on the face B is leveled,
It can also be used to finish with.

Further, the mounting member 15 and the flow pipe 16 are rotatable and fixed by screws.
If is rotatable, it is not always necessary to fix with screws. For example, when the mounting member 15 and the flow pipe 16 are not fixed with screws or the like, when painting is performed from the upper part to the lower part of the painted surface, the angle between the flow pipe 16 and the painted surface continuously changes. I will be. Even if the angle is changed in this manner, the brush members 20, 21 can be brought into close contact with the painted surface.

FIG. 5 shows a second embodiment.
The greatest feature of the second embodiment is that the two rods 1
3 and 14 are fixed to a mounting member 29 so as to be parallel to each other, and the mounting member 29 is formed with an ejection hole 17 for opening the flow path of the flow pipe 16 to the rod side. Components other than this feature are substantially the same as in the first embodiment. The same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof will be omitted.

As shown in FIG. 5, the coating roller body D
Is a mounting member 29 to which the rods 13 and 14 are fixed,
The flow pipe 16 rotatably connected to the mounting member 29
And The two rods 13 and 14 are fixed to a mounting member 29 so as to be parallel to each other, and the mounting member 29 is formed with an outlet 30 for opening the flow path of the flow pipe 16 to the rod side. In the second embodiment,
The mounting member 29 also serves as a jetting portion.

The flow pipe 16 is connected to a grip 19, and the flow pipe 16 is provided with a flow control throttle 18. The brush members 2 are attached to the rods 13 and 14.
0 and 21 are attached.

The spout 30 formed in the mounting member 29 is formed so as to be located between the two rods 13 and 14. Since the brush members 20, 21 are attached to the two rods 13, 14, as a result, a spout 30 is formed between the brush members 20, 21. Then, the paint pumped from the distribution pipe 16 is supplied to the jet port 30.
From the rods 13 and 14 in the axial direction. The jetted paint passes between one of the brush members 20 and the other brush member 21 and passes through the brush members 20,
At the same time as reaching the tip side of 21, it is jetted directly onto the painted surface. Further, the paint ejected in this manner does not scatter by the brush members 20 and 21 except for the painted portion.

The mounting member 1 having the above-described ejection port 30 formed therein
5 is rotatably connected to the flow pipe 16, and by thus being rotatably connected, the two brush members 20, 21 come into close contact with the painted surface. That is, when an attempt is made to paint from the upper part to the lower part of the painted surface, the angle between the flow pipe 16 and the painted surface continuously changes. Even if the angle changes in this way, if the attachment member 29 is rotatable with respect to the flow pipe 16, the brush members 20, 21 can be brought into close contact with the painted surface.

Next, the operation of the second embodiment will be described. When the lever 22 provided on the grip 19 is gripped, the paint is supplied from the paint supply hose 23 to the distribution pipe 16 by air pressure. The paint supplied to the flow pipe 16 is supplied from the jet port 30 by the pressure to the two brush members 20 and 2.
Squirted during one. The jetted paint uses the two brush members 20, 21 as a guide, and the brush members 20, 21 are used as guides.
21 and is sprayed directly onto the painted surface.

As described above, since the mounting member 29 also serves as the jetting portion, the paint can be jetted toward the brush members 20 and 21 only by providing the jetting port 30 in the mounting member 29. In addition, since the ejection section is not specially provided, the ejection section does not interfere with painting. Therefore, work efficiency can be improved. Furthermore, since there is no need to provide a special jetting portion, the number of parts can be reduced, and the size of the entire coating roller can be reduced.

In this embodiment, the paint is applied to the brush members 20,
Since the paint does not directly hit the brush member 21, the brush members 20, 21
But it doesn't hurt locally. Brush member 20, 2
1 does not hurt locally, the brush members 20,
The coating unevenness due to settling of 21 is eliminated. Therefore,
Clean coating is possible over a long period of time. Moreover, 2
The two brush members 20, 21 can prevent the paint from scattering.

In this embodiment, two rods are used.
However, three or more books may be used. For example, when three rods are used, they can be positioned as shown in FIGS. 4A and 4B of the first embodiment. That is, FIG.
As shown in (a), three rods can be fixed in a straight line, and a brush member can be attached to these rods. As described above, when all of the three rods are provided on a straight line, a spout may be provided between each brush member. FIG. 4 (b)
When the brush members are arranged so as to be triangular as described above, an ejection port is provided at the center of the brush members.
