Description

[Detailed Description of the Invention] The present invention relates to an improvement of a roller used to apply a three-dimensional pattern on-site to a coating material applied to a wall or ceiling.

Generally, cement-based, plaster-based, painted on walls and ceilings,
For the purpose of adding a three-dimensional pattern to the coating surface of a coating material such as synthetic resin, a roller with a convex part of an arbitrary pattern is used.
A method using a pattern roller has already been implemented in which the roller is rotated while being pressed to create depressions corresponding to the convex portions of the roller on the surface of the coating material, thereby forming a three-dimensional pattern of unevenness on the surface of the coating material as a whole. ing.

In this method, as shown in FIG.
In order to form a convex portion 1, the roller B used therein needs to have a concave portion 2 corresponding to the convex portion 1.

However, when the recess formed in the roller is cylindrical, for example, as described above, it is difficult to remove the coating material that has entered the recess 2 while reliably maintaining its shape.

Therefore, when using a roller having such an uneven part, the surface of the roller is covered with a thin and stretchable nylon knitted fabric 3 to make it easier to introduce air to the bottom of the recess 2 during demolding. , we have taken measures to ensure that the mold can be removed.

However, with this method, depending on the type of coating material, the nylon knitted fabric may gradually become clogged, making it difficult to introduce air, which makes it difficult to remove the mold during long-term continuous use, or the nylon knitted fabric may become clogged depending on the type of coating material. This has disadvantages such as a change in the smoothness of the surface of the coating material after demolding due to the sticking of the coating material, and severe wear and tear on the nylon knitted material.

The inventor of the present invention came up with the present invention after studying a roller that eliminates the drawbacks of conventional pattern rollers as described above when forming a three-dimensional pattern having discontinuous convex portions on the surface of a coating material. .

The present invention will be explained below with reference to the drawings showing one embodiment thereof.

As shown in FIG. 1, the hand roller C of the present invention has a cylindrical roll base 11 in which a plurality of through-holes or through-grooves 12 of a desired design and shape are discontinuously formed, and is rotatably fitted onto a support shaft 13. The handle 14 is fixed to the other end.

Next, to explain the state in which a three-dimensional pattern is formed on the surface of a coating material using the roller C having such a structure, when the roller C is pressed against the surface A of the coating material as shown in FIG. Enter the position D in the through hole 2 of the roller C.

Then, when this roller C rotates and the previous position D moves away from the position E, that is, the surface of the coating material, the coating material a forms the convex portion 1 without changing the shape formed by the through hole 2. It is possible.

This is because reducing pressure does not work like the recesses in conventional pattern rollers.

If the roller of the present invention is used and there is a function that tries to break the shape of the convex part 1, it is only the shearing friction force between the coating material a and the wall of the through hole 2, and this is caused by the roller C. This can be prevented by reducing the thickness of the roll base 11, and at the same time, a cohesive force that exceeds the tensile force applied to the coating material a forming the convex portion 1 when the roller C rotates is given in advance to the coating material a side. This can be resolved by doing this.

Furthermore, when forming a three-dimensional pattern of unevenness on the coating material surface using the roller of the present invention, the height of the convex portions 1 can be made uniform by making the thickness of the coating material uniform in advance. .

Compared to conventional pattern rollers, the hand roller of the present invention is particularly effective when forming patterns such as discontinuous through holes, but even when forming patterns such as continuous through grooves. It is possible to form a three-dimensional pattern with extremely excellent unevenness.

In the present invention, the material of the roll base in which the through holes or grooves are formed as described above may be synthetic resins such as vinyl chloride resin, polyolefin resin, fluororesin, high impact styrene, natural rubber, synthetic rubber, polyurethane elastomer, etc. However, materials such as metal or water-resistant paper tubes can also be used.

In short, the present invention simply involves providing through-holes and through-grooves of the desired design and shape on the roll base as described above, so it is not only possible to obtain it very easily and inexpensively compared to conventional pattern rollers. Its practical effects are particularly great.
