[Industrial applications]

 The present invention relates to an applicator used for applying ink, paint, paint, etc., and has an excellent application effect by incorporating an elastic body having a novel shape.

[0002]

[Prior art]

 Conventionally, a brush, a brush or a roller device for application is used to apply ink, paint or paint. Especially when the application surface is wide, the application roller device as shown in FIG. 5 is often used. In FIG. 5, one end of the holder b is inserted through the rotary shaft c of the coating roller a and the thumbscrew d is tightened to fix the coating roller a so that it can rotate, and the other end of the holder b is bent. Form a grip handle e. To use this applicator, an applicator such as an ink is applied to the applicator roller a, and then the applicator is brought into contact with the applicator surface and rotated to apply the applicator. However, the coating roller a is suitable for uniformly coating a wide surface because the entire roller width contacts the coating surface due to its structure, but it is almost impossible to change the coating width or draw a curve. It was possible and had the drawback of having to rely on a brush or a brush to draw the curve.

[0003]

[Problems to be solved by the device]

 SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks of the prior art and to provide an application device capable of freely changing the application width and drawing a complicated shape such as a curved line.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises an elastic rotating body having a projecting surface whose section including a rotating shaft shows a smooth curve, and a holder having a rotating shaft supporting portion at one end and a grip handle at the other end. In addition, the rotating shaft supporting portion supports the rotating shaft of the elastic rotating body.

[0005]

[Action]

 When a coating material such as ink, paint or paint is attached to the elastic rotating body and brought into contact with the application surface, the elastic rotating body is deformed according to the contact pressure and the contact area changes. The higher the width, the wider the applied width, and the lower the contact pressure, the narrower the applied width. Further, when the contact pressure is lowered, the contact width of the elastic rotating body with respect to the coating surface becomes narrower, so that it is possible to run in a curved line unlike a conventional roller and easily draw a curve.

【Example】

 FIG. 1 is a front view of an applicator according to the present invention, and FIG. 2 is a side view of FIG. In the figure, A is an elastic rotating body for application in which urethane foam is molded into a spherical shape as an elastic rotating body having a projecting surface whose section including the rotation axis shows a smooth curve. The elastic rotating body A is rotated. Therefore, a bearing tube 2 made of synthetic resin is fitted through the center 1 of the sphere. B is a holder for holding the elastic rotating body A. The elastic rotating body A is formed by bending a metal rod to form the elastic body supporting portion 3 at one end and inserting the elastic rotating body A into the bearing tube 2. A grip handle 7 is attached to the other end so that it can be easily held by the hand. In order to prevent the elastic rotating body A from falling off, a thread groove 4 is cut and a thumbscrew 5 is screwed through a washer 6 at the tip of the elastic body supporting portion 3. On the holder bending portion 7a side of the elastic body support portion 3, a locking portion 8 is provided so as to prevent unnecessary movement of the elastic rotation body A during use, and the elastic rotation body A is mounted via the washer 6 '. I am trying to install it. In the above embodiments, the sphere was used as the form of the elastic rotating body A, but the elastic rotating body A is not limited to the sphere, and may be in the form of a rotating body having a protruding surface whose section including the rotation axis shows a smooth curve.

As another embodiment, an ellipsoidal body 9 as shown in a sectional view including a rotation axis in FIG. 3 and a spherical body 11 at the center of a cylindrical rotating body 10 as shown in the sectional view in FIG. It is also possible to use an elastic rotating body formed with. Further, as the material of the elastic rotating body A, in addition to urethane foam, rubber, foamed rubber, soft synthetic resin, foamed synthetic resin or the like, which is elastic, flexible and easily deformable, is preferable.

When using the applicator of the present invention, first hold the grip handle 7 in the hand to attach the application material such as ink to the elastic body A, and then attach the elastic rotating body A to the surface to be applied. The application can be performed by bringing the elastic rotating body A into contact with each other and moving the elastic rotating body A while rotating. At this time, if the elastic rotating body A is strongly pressed, the elastic rotating body A is largely deformed, the contact area between the elastic rotating body A and the surface to be coated is increased, and a wide coating surface is obtained. The contact area is reduced and a narrow coated surface can be obtained.

[0009]

[Effect of device]

 As described above, according to the present invention, since the elastic rotating body having the protruding surface showing a smooth curve in the cross section including the rotating shaft is assembled, the application force can be applied by one tool by controlling the force pressing the elastic rotating body. The width of the coating material to be applied can be changed to be wider or narrower, and the direction of application can be easily changed when the width to be applied is narrow, so that a curve can be drawn. It is also possible to draw a pattern similar to a circle, ellipse, etc. by tapping the surface to be coated with the elastic rotating body to which the coating material is attached. Furthermore, when it is used as a learning tool for children's painting learning, it can draw various shapes with a single tool, which is very useful for emotional education.
