Illustrating tool

Abstract

A finger brush, which is an illustrating tool, includes a brush tip portion for illustrating and a main body portion. The main body portion is in a hollow elongated shape having one end supporting the brush tip portion and the other end receiving a finger inserted therein. In the main body portion, a slit extending in the axial direction of the main body portion and reaching the other end is formed. The main body portion has a tapered portion having a cross-sectional area getting smaller toward the other end in the axial direction of the main body portion. A finger inserted into the main body portion forces the tapered portion to spread out, causing the finger to be secured inside the main body portion. Such a configuration can provide an illustrating tool which is worn on a finger and can provide a good sense of wearing without compromising a sense of unity with a finger.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention generally relates to an illustrating tool for illustrating, and more specifically to a brush used in a finger-worn mode of use and for calligraphy, painting, colouring, making up, and the like.[0003]2. Description of the Background Art[0004]For example, Japanese Utility Model Laying-Open No. 64-17783 (Patent Document 1) discloses a finger brush in which a brush tip of the brush can be directly fitted onto a human fingertip. The finger brush disclosed in Patent Document 1 has a shaft portion in a hollow elongated shape having an inner diameter allowing a fit onto a fingertip.[0005]Further, Japanese Utility Model Laying-Open No. 62-166078 (Patent Document 2) discloses a fingertip brush fitted onto a fingertip for writing a character or painting. The fingertip brush disclosed in Patent Document 2 is formed of a brush tip cylinder into which a brash tip of the brash is fitted and a fingertip cylinder t...

AI Technical Summary

Benefits of technology

[0010]An object of the present invention is to solve the above-described problems and to provide an illustrating tool which is worn on a finger and can provide a good sense of wearing, without compromising a sense of unity with a finger.

[0012]According to the illustrating tool configured in this way, the finger inserted in the main body portion is held by the tapered portion at one point on the other end side. This can achieve a good sense of wearing, while providing a moderate sense of fit which does not compromise a sense of unity with the finger.

[0013]Further, preferably, the main body portion further has a reverse-tapered portion. The reverse-tapered portion is connected to the tapered portion and has a cross-sectional area getting smaller toward the one end. At a position where the tapered portion and the reverse-tapered portion are adjacent to each other, the main body portion has a largest cross-sectional area. According to the illustrating tool configured in this way, at a position where the main body portion has a largest cross-sectional area, the last joint of a finger, which has a wide width, can be positioned. This can reduce compression of the last joint of a finger inside the main body portion and achieve a superior sense of wearing.

[0015]As described above, according to the present invention, an illustrating tool which is worn on a finger and can provide a good sense of wearing without compromising a sense of unity with the finger, can be provided.

Problems solved by technology

For this reason, a brush is more difficult to handle than a pencil, a ballpoint pen and the like, which is a background to the brush.

In a brush with such a configuration, however, if a sense of unity between the finger and the brush cannot be achieved, then a writer cannot handle the brush as he or she desires.

Further, when the fit of the finger to the shaft portion is tightened to achieve a sufficient sense of unity, a blood flow in the finger can be interrupted, causing a pain to the writer.
