BACKGROUND OF THE INVENTION The present invention is applied to a grip of a stick-like writing instrument such as a ball-point pen, so that the force applied to the fingertip during writing can be efficiently applied to the tip of the writing instrument, resulting in a light force. The present invention relates to an auxiliary tool for a writing instrument, which is easy to grip and can be used for writing for a long time without getting tired.

[0002]

2. Description of the Related Art Conventionally, a writing instrument having a stick-like shape such as a ballpoint pen is generally written while gripping it with three thumbs, an index finger and a middle finger, but it is easy to slip due to writing pressure when writing, and a relatively large writing pressure is required. Therefore, when writing for a long time, fatigue is accumulated on the fingertips, wrists, shoulders, etc., and as a result, it is inevitable that symptoms such as cervical-shoulder-arm syndrome occur.

Therefore, in order to eliminate the above-mentioned adverse effects, the gripping portion provided with an uneven portion or the gripping portion having a large diameter has been used, but it is still strong with the above-mentioned three fingers. Due to the balance between the frictional force generated by the pressure on the tip of the writing instrument while clasping it and the writing pressure from the tip, the above-mentioned adverse effects could not be eliminated.

[0004]

Therefore, the inventor of the present invention projects a mounting piece to which a fingertip is to be mounted outwardly in the vicinity of the tip of a base fixed to the outer peripheral surface of the grip of a writing instrument. We have proposed a writing aid and a ballpoint pen.
No. 7853 and Jpn. Pat. Appln. No. 4-67854) can cope with these problems because the writing piece is held differently depending on the individuality of the user such as right-handed or left-handed because the position of the mounting piece is limited. In addition, when used for a writing instrument such as a ballpoint pen, the tip ball is unevenly worn and has a problem that it cannot withstand long-term use.

The present invention has been devised to solve the drawbacks of the conventional products described above, and is attached to the grip portion of a stick-shaped writing instrument such as a ball-point pen that has been generally used in the past. It is possible to use the power efficiently with the movement of one forefinger without being influenced by the movement, and the writing with a light force and the easy grip enable the user to write for a long time without getting tired. It is an object of the present invention to provide an auxiliary tool for a writing instrument that does not cause uneven wear due to the use of the tip of the writing instrument.

It is preferable that the surface is a surface, and the inner surface may be subjected to anti-slip processing if necessary.

Next, the placing piece according to the present invention is formed so that the front end side on which the fingertip of the index finger is placed is relatively wider than the rear end side and extends substantially parallel to the holding portion of the writing instrument. From the viewpoint of writing, it is preferable that it is a flat plate body that has been formed, and both the surface side both sides of the tip side of the above-mentioned placing piece are downward in order to ensure good placement of the fingertip during use. It is preferably an inclined surface curved toward the outside.

Further, while the rear end side of the placing piece described above makes the placement of the fingertip on the placing piece good, the rear end side thereof can be used as a clip for storing the writing instrument. It is preferable that the inclined plate is inclined obliquely downward so as to face toward.

Next, as the support piece in the present invention, the tip portion of the fixed portion with the gripping piece and the mounting portion are placed so that the pressure of the fingertip of the forefinger applied to the mounting piece is efficiently applied to the tip portion of the writing instrument. The angle at the rear end of the fixed portion with the mounting piece is made acute, and each hanging side extending from the fixed portion with the mounting piece to the fixed portion of the gripping piece is inclined toward the tip end side of the gripping piece. Therefore, it is preferable that the plate body has a vertical cross-sectional shape in a ladder shape with respect to the axial direction of the gripping piece.

In addition, in order to improve the fit property to the fingertip, a fine uneven portion is provided on the surface on the tip end side of the above-mentioned placing piece to make it rough and to have a shallow dent along the curved surface of the fingertip. Is preferably provided.
