Description

[Detailed description of the invention] The present invention is a paint pumping type painting device that can be handled in the same way as a conventional roller brush type painting device.
Moreover, the present invention provides a coating device using a non-rotating plate-like brush that can apply coating by rubbing the coating material onto the surface to be coated, as in the case of brush coating.

Hereinafter, one embodiment of the present invention will be described based on the attached illustrative drawings. Reference numeral 1 denotes a handle that also serves as a paint supply pipe, and at its tip, a sideways paint is discharged through a bent pipe 2 and an elbow 3. One end of the tube 4 is supported.

This paint discharge pipe 4 does not rotate, but has a fitting 5 attached to its base so that it can only rotate. A screw shaft portion 5a for positionally fixing a roller brush, a plate-shaped brush described below, etc. is provided concentrically.

Reference numeral 6 denotes a rotary body fitted into the paint discharge pipe 4 from its free end side, and has a female screw hole 6a concentrically formed on the inner end side.
The threaded shaft portion 5a of the fitting 5 is screwed into the female threaded hole 6b formed on the outer end side, and a tapered hole 7a that fits into the free end of the paint discharge pipe 4 is concentrically formed. Cap 7 in preparation for
are screwed together, and as a result, the rotating body 6 is connected to the paint discharge pipe 4.
The cap 7 is supported so that it can only rotate, and the resistance during rotation is adjusted by the threading allowance of the cap 7.

Reference numeral 8 denotes a rectangular flat plate-shaped portion, which is connected to one side of the rotating body 6 so that the rotating body 6 is located at the center position in the width direction and parallel to the axial direction of the rotating body 6. has been established,
A slit (a plurality of small holes may also be used) that communicates with a passage 9 formed in the rotating body 6 so as to surround the paint discharge pipe 4.
It is equipped with 10.

Reference numeral 11 denotes a plate-shaped brush, which is provided with engagement grooves 12 on both sides of the flat plate-shaped portion 8 and has a large number of through holes 13, and a substrate 14 on the outer surface of the substrate 14. The brush main body 15 is made of a flocked brush cloth (pile fabric, etc.) attached.

When the engagement grooves 12 on both sides are fitted to both sides of the flat plate-shaped portion 8, the substrate 14 is fixed in position by frictional force while covering the entire outer surface of the flat plate-shaped portion 8. It is configured as follows.

At this time, if there is a risk that the paint may leak inappropriately from the gaps between the front and rear edges that do not have the engagement groove 12 and the front and rear edges of the flat plate-shaped portion 8, as shown in FIG. Groove portions 16a and 16b can be provided on both front and rear sides of the flat plate-shaped portion 8 to tightly fit with both front and rear sides (the rear side is folded back to the front side).

The method of use is no different from that of conventional roller brush painting equipment that pumps paint.

That is, the paint is forced into the paint discharge pipe 4, and is discharged from the passage 9 in the rotating body 6 through the slit 10 and the numerous through holes 13 to the entire area inside the brush body 15 of the plate-shaped brush 11.

In this state, the brush main body 15 of the plate-shaped brush 11 is brought into contact with the surface to be painted, and the plate-shaped brush 11 is slid on the surface to be painted using the handle 1.

At this time, since the plate-shaped brush 11 can rotate together with the rotating body 6 around the paint discharge pipe 4, the entire surface of the plate-shaped brush 11 is in contact with the surface to be painted, regardless of the angle of the handle 1 with respect to the surface to be painted. Can be maintained.

In this painting work state, when the plate-shaped brush 11 is separated from the surface to be painted, the cap 7 is tightened to such an extent that the plate-shaped brush 11 does not rotate freely due to gravity around the paint discharge pipe 4, which is the central axis of rotation. By providing appropriate rotational resistance to the plate-shaped brush 11 with a screw thread, not only can the initial operation of bringing the plate-shaped brush 11 into contact with an arbitrary position on the surface to be painted be easily performed, but also the plate-shaped brush 11 When sliding the plate-shaped brush 11 on the surface to be painted, prevent the plate-shaped brush 11 from tilting due to the resistance between it and the surface to be painted, so that the edge in the sliding direction gets caught on the surface to be painted. can be prevented and smooth sliding can be made possible.

The plate-shaped brush 11 can be removed from the flat plate-shaped portion 8 of the rotating body 6 to be cleaned or replaced.

Further, the rotating body 6 can also be removed from the paint discharge pipe 4 by relatively rotating the fitting 5 and the rotating body 6 and separating the fitting 5 and the rotating body 6.

A conventional roller brush is rotatably fitted into the paint discharge pipe 4 from which the rotating body 6 has been removed, and the position is fixed by the fixture 5, so that the coating device of the present invention can be replaced with the conventional roller brush type. It can also be used as a coating device.

The coating device of the present invention can be implemented as in the above embodiment, and can apply brushes in the same way as brush painting by using the same efficient coating method as the conventional roller brush type paint pressure-feeding type coating device. It is possible to apply the product by rubbing it on the painted surface.

Therefore, the coating device of the present invention can be used extremely effectively even in sites where conventional roller brush type paint pumping type coating devices cannot perform painting due to the phenomenon of bubbling on the painted surface due to the paint.

In addition, the rotary body 6 with a plate-shaped brush can be removed from the paint discharge pipe, and the plate-shaped brush can be removed from the rotary body, making it easy to clean the area that will become the paint passage and replace the brush. This can be done easily if necessary, and it is economical because a conventional roller brush type paint pumping type coating device with the roller brush removed can be used as is.
