Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coating roller with a simple structure suitable for applying paint to the corners of a wall.

[Prior technology] Tokkosho's roller brush for painting the corners of walls
There is a method published in Publication No. 52-45325, in which a paint supply pipe that also serves as a handle is connected to the unbranched shaft of a Y-type joint, so that the axes of the two branched shafts are perpendicular to each other. Two paint supply pipes are connected to each other, and a roller brush is rotatably supported on each supply pipe.

The roller of the roller brush is a roller equipped with a cylindrical unit having a through hole in the center for inserting the paint supply pipe, and the unit consists of two parts connected in the axial direction, with a space between the two parts. In the connected state, a paint passage is formed that guides the paint from the inside of the through hole to the outer periphery, and each of both parts has a recess that opens at the free end on the opposite side from the side where the paint passage is formed. and a fitting portion provided at the free end of one component and a fitted portion that is provided at the free end of the other component and is fitted with the fitting portion of another unit adjacent in the axial direction. and a mating part, and the mating part and the mating part are such that when adjacent units are mated and connected to each other, the recessed part is sealed from the central through hole and the outer peripheral part of the roller. The main feature of the roller is that it has a hollow section, and a roller of a desired length can be obtained by simply connecting any number of single units of one type.

[Problems to be solved by the invention] However, conventional brushes of this type perform painting while supplying paint through a paint supply pipe, and the brush itself is designed to be a stand-alone brush for easy cleaning. The configuration of the roller is complicated, such as having two components that can be disassembled.

[Means for Solving the Problems] In the present invention, in order to solve the above-mentioned problems, a bifurcated support shaft is provided at the tip of the support rod with a handle fixed to the rear end. A roller that is fitted onto a shaft is connected to a cylindrical drum having an opening at one end, a cap that is press-fitted into the opening of this drum, and a cap that is rotatably fitted to the tip of the shaft of this cap. The cap is composed of a collar having a slot along the axial direction and a pad fixed to the outer peripheral surface of the drum via a base fabric, and the cap has a flange at one end of the shaft, and the cap has a flange at one end of the shaft. A through hole is formed that passes through the center and communicates with the opening formed at the tip of the shaft, into which the support shaft of the support rod fits, and the collar is rotatably inserted into the opening of the shaft. We adopted a structure that allows them to fit together.

[Function] When the above-described structure is adopted, the base body of the roller is formed by simply press-fitting the shaft of the cap into the opening of the drum with the collar fitted into the opening at the tip of the cap. Since the coating roller can be constructed by fixing the pad to the outer periphery of the drum via the base cloth, it is extremely easy to manufacture the roller.

When this coating roller is attached to the support shaft of the support rod, the collar prevents the roller from deviating from the support shaft and creates a space between the outer circumference of the collar and the inner circumference of the opening of the cap. This allows the roller to rotate smoothly and coat corner walls reliably.Also, since the collar has a slot, the diameter of the collar can be expanded freely, making it easy to attach and detach the roller from the spindle. be.

[Example] Hereinafter, details of the present invention will be explained based on an example shown in the drawings.

Figure 1 and the following diagrams explain one embodiment of the present invention. In the figure, the reference numeral 1 indicates a support rod, which is made of a steel rod or the like, and a handle 2 is fixed to the rear end of the support rod. .

At the tip of the support rod 1, two bifurcated support shafts 3, 3 are integrally provided. The opening angle between these support shafts 3 and 3 is as shown in Figure 4.
The plane which is 90 degrees and includes the two support shafts 3, 3 intersects the support rod 1 at a predetermined angle, for example, 120 degrees, as shown in FIG.

Furthermore, a tapered surface 3a is formed at the tip of each of the support shafts 3, 3, and the tapered surface 3a becomes thinner toward the tip.

A roller 4 having a structure as shown in FIGS. 7 to 10 is rotatably supported at the tip of each support shaft 3.

That is, the drum designated by reference numeral 5 in the figure is formed into a columnar shape from synthetic resin or wood, and has a circular opening 5a formed at one end with a predetermined depth.

A cap 6 is fitted and fixed into this opening 5a.

The cap 6 is integrally molded from synthetic resin or the like, and has a shaft portion 7 and a flange 8.

The diameter of the shaft portion 7 is approximately equal to the inner diameter of the opening 5a, and the length thereof is approximately the same as the depth of the opening 5a. Two grooves 7a having a right triangular cross section are formed along the entire circumference of the shaft portion 7 at a predetermined interval.

The upright wall of this groove 7a is located on the tip side of the shaft portion 7.

By forming these grooves 7a, 7a, a protrusion 7b having a right triangular cross section is defined between them. The upright wall of this protrusion 7b is on the flange 8 side.

Further, a tapered surface 7c is formed at the tip of the shaft portion 7 so that it can be easily fitted into the opening 5a. As shown in FIG. 7, an opening 7d having a predetermined diameter is formed at a predetermined depth in the center of the tip of the shaft portion 7, and a flange 8 side is formed in communication with the opening 7d. A through hole 8a is formed therethrough. The diameter of this through hole 8a is smaller than the diameter of the opening 7d.

On the other hand, the diameter of the flange 8 is slightly larger than the diameter of the drum 5, and a tapered surface 8b having an inclination angle of 45 degrees is formed on the outer side of the circumferential surface.

Further, a collar 9 is provided in the opening 7d of the shaft portion 7.
are rotatably fitted. The collar 9 is formed, for example, by winding a metal plate into a cylindrical shape, and a slot 9a is formed in a part of the collar 9 along the axial direction. A tapered surface 9b is formed on the inner diameter side of the upper and lower ends of the collar 9, and the diameter becomes larger toward the outer end.

Note that if the inner diameter of the collar 9 in its free state is d ₁ and the diameter of the support shaft 3 is d ₂ , then d ₁ <d ₂ , and the support shaft 3 is connected to the cap 6 through the through hole 8a.
When the collar 9 is fitted through the slot 9
The diameter is expanded from the part a, but even in this state, as shown in FIG. There is a slight gap between
Roller 4 can rotate freely.

This structure was adopted because if paint or other paint adheres to the roller 4 and the roller 4 becomes unusable,
This is to enable the roller 4 to be freely replaced and disposable.

On the other hand, the one designated by the reference numeral 10 is formed by flocking fine fibers 12 onto a padded bag-like base fabric 11.

The diameter of the base fabric 11 is approximately equal to the diameter of the drum 5, and its depth is approximately equal to the length of the drum 5.

This pad 10 is fixed to the outer peripheral surface of the drum 5 with an adhesive through a base fabric 11.

The rollers 4 having the above-described structure are rotatably attached to the respective support shafts 3 as shown in FIGS. 1 to 3.

In the installed state, there are 2
The rollers 4, 4 are arranged with the same opening angle as the opening angle of the support shafts 3, 3, that is, an angle of 90 degrees.

Next, a method of using the coating roller configured as above will be explained.

The painting roller proposed in this invention has two wall surfaces that are approximately
Used only for painting corners of walls that intersect at a 90 degree angle.

In such a case, hold the handle 2 and move the rollers 4, 3 so that the support shaft 3 is perpendicular to the corner where the walls 13, 13 intersect, as shown in FIGS. 11 and 12.
Press 4.

At this time, since the support shaft 3 and the support rod 1 intersect at an angle of 120 degrees, the handle 2 side moves away from the wall surface 13, making it extremely convenient to use even when the roller 4 is moved up and down.

In this way, the rollers 4, 4 are connected to the wall surfaces 13, 13.
12, the rollers 4, 4 simultaneously press the two wall surfaces 13,
Touches the corner of 3.

When the rollers 4, 4 are moved up and down in this state, the paint impregnated in the pad 10 of the roller 4 is removed from the wall surface 13.
applied to the sides.

[Effects] As is clear from the above description, according to the present invention, a bifurcated support shaft is provided at the tip of the support rod, and the roller that is fitted onto this support shaft is arranged in a circular shape having an opening at one end. A columnar drum, a cap press-fitted into the opening of the drum, a collar rotatably fitted to the tip of the shaft of the cap and having a slot along the axial direction in a part thereof; Since the pad is fixed to the outer peripheral surface of the drum via the base fabric, the shaft of the cap is press-fitted into the opening of the drum with the collar fitted into the opening at the tip of the cap. The roller is extremely easy to manufacture because the coating roller can be constructed by forming the base of the roller using a chisel and fixing the base to a pad via a base cloth around the outer periphery of the drum.

When this painting roller is attached to the support shaft of the support rod, the collar prevents the roller from deviating from the support shaft and creates a gap between the outer circumference of the collar and the inner circumference of the opening of the cap. This allows the roller to rotate smoothly and coat corner walls reliably.Also, since the collar has a slot, the diameter of the collar can be expanded freely, making it easy to attach and detach the roller from the spindle. be.
