Description

Roller for painting {Roller for painting}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller for painting, and more particularly, to a roller for painting for painting corners of walls and ceilings, round columns, square columns, and the like.

In general, the walls of the building or the surface of the structure is painted to protect the surface and aesthetics.

In the paint as described above, a roller, a brush, or the like is used. The shape of the conventional roller described above is as shown in FIG.

The roller 10 has a rotating shaft 12 is formed so that the cylinder 11 is rotatable, and one end of the rotating shaft 12 is bent and extended to form a rod 13 for connecting the handle 14. do. In the outer periphery of the cylinder 11, a plurality of thin threads 15 are wound or wrapped in a cloth in which a plurality of thin hairs are planted.

When the worker immerses the cylinder 11 of the roller 10 in a container containing a paint solution in order to paint with the roller 10 as described above, the paint liquid is adsorbed to the seal 15 by a certain amount, and the paint When the adsorbed roller was removed from the container and the surface of the wall or the structure was pushed, the cylinder 11 was rotated along the wall and the paint liquid adsorbed to the seal 15 was applied to the surface of the wall or the structure by a predetermined amount.

However, the cylindrical rollers as described above did not have a big problem in painting the flat part of the wall surface, but due to the characteristics of the cylindrical roller, the outer circumference of the roller does not touch the paint so that the roller is not painted. In the case of a circular column, the outer periphery of the column and the outer periphery of the roller cylinder were in line contact, so there was a problem of having to paint several times. Therefore, the wall and ceiling corners and round pillars would be painted with a brush.

Therefore, the present invention has been made to solve the above problems, and more particularly to provide a roller for painting for painting the corners of the wall and ceiling, a circular pillar or a square pillar.

The present invention as a means for achieving the above object,

One end of the rotating shaft is connected to the rod and the handle which are bent and extended, and the rotating body rotating on the rotating shaft is supported. A plurality of thin threads are planted on the outer circumference of the rotating body to allow the paint solution to be adsorbed. In the roller to paint,

To form a shaft insert for accommodating the end of the rotating shaft to the inner side of the rotating body, to form a screw thread for connecting to the pole on the inner circumference of the handle end, and to form projections to prevent slipping on the outer peripheral surface of the handle, The outer periphery of the rotating body is characterized in that the cross-sectional shape is a rhombic shape so that it can be painted on the wall or the corner of the ceiling,

The outer peripheral shape of the rotating body has a cross-sectional shape of " "It is characterized by being able to paint the outer circumference of the circular pillar by being configured in a shape,

The outer peripheral shape of the rotating body has a cross-sectional shape of " "It is characterized by being able to paint the corners, etc., so as to be configured in the shape.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of the roller for painting formed by the present invention, Figure 2 is a state of use of the roller formed by the present invention is a state of painting the corner of the wall, Figure 3 is connected to the pole formed by the present invention to the pole 4 and 5 are cross-sectional views and use state diagrams of rollers formed by other embodiments of the present invention, and FIGS. 6 and 7 are cross-sectional views and use state diagrams of rollers formed by another embodiment of the present invention. .

Reference numeral 20 shown in the drawing indicates a rotating body of the roller formed by the present invention, and reference numeral 21 indicates a rotating shaft.

The rotating body 21 of the roller 20 is inserted into the rotating shaft 22, the rod 23 is formed as one end of the rotating shaft 22 is bent and extended in the 90 ° direction, the rod A handle 24 is formed at the end of 23.

The rotating body 22 has a cross-sectional shape of a rhombic shape, and a plurality of thin threads 26 may be wound on the outer circumferential surface of the rotating body 22 of the rhombic shape. In addition, the outer circumferential surface of the rotating body 22 may be wrapped with a coating in which a plurality of thin threads are planted.

The rotating body 22 is formed by combining the upper body and the lower body with synthetic resin, respectively, the shaft insertion portion 21a is formed at one side thereof so that the engaging jaw 22a formed at the end of the rotating shaft 22 can be caught. A part of the corner of the other one axis of the rotating body 21 is formed in a plane for smooth rotation of the rotating body.

In addition, a plurality of protrusions 24a are formed on an outer circumferential surface of the handle 24 of the roller 20 to prevent slippage when the worker grips them by hand, and a pole 26 is formed on the inner circumference of the lower side of the handle 24. ) Is formed with a threaded portion 24b.

The roller 30 shown in FIGS. 4 and 5 is formed by another embodiment of the present invention, and the outer circumferential shape of the rotating body 21 is curved to paint a curved surface such as a circular column. That is, the outer peripheral shape of the rotating body 21 has a cross-sectional shape of " "It consists of shapes.

And the roller 40 shown in Figures 6 and 7 is formed by another embodiment of the present invention, the outer peripheral shape of the rotating body 21 to paint the corners, etc. of the wall surface is a right angle. That is, the outer circumference of the rotating body 21 has a cross-sectional shape of " "It consists of shapes.

Referring to the operation and action of the paint roller configured as described above are as follows.

When the worker paints the corners of the wall or ceiling, the corners may be painted with the rollers 20 formed in a rhombus cross section as described above. At this time, since the rotating body 21 is formed in a rhombus shape, both wall surfaces of the corner part may be simultaneously painted. Therefore, it is not necessary to use a brush to paint the corners of the wall or ceiling as in the prior art.

In the case where the circular column is to be painted, the roller 30 may be painted as described above with a curved surface. That is, the outer periphery of the cylinder is painted by using the roller 30 corresponding to the radius of the circular column, so that the work efficiency is significantly improved than the conventional cylindrical roller.

In addition, when the square pillar is painted, the cross-sectional shape is " It is possible to paint by using the roller 40 which becomes a shape. That is, when the edges of the wall surface are painted, the wall surfaces on both sides can be painted at the same time, thereby reducing the paint stain between both sides.

By using the roller formed as described above to paint the corners of the building wall or ceiling and round or square pillars, there is an advantage that does not need to paint using a brush as in the prior art, high wall or ceiling corners and corners and When painting the corners of the circular column or the wall surface can be used by connecting the pole to the screw formed on the lower portion of the handle, even if you hold the handle by hand has the advantage of preventing slipping due to the projection formed on the outer periphery of the handle.
