Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an auxiliary tool for a writing instrument that is attached to the grip of a stick-like writing instrument such as a ballpoint pen or pencil, and in particular, the force applied to the fingertip during writing is efficiently applied to the tip of the writing instrument. The present invention relates to an auxiliary tool for a writing instrument that can be applied over a long period of time without being tired, with a light force and a comfortable grip.

[0002]

[Prior art]

 Conventionally, writing instruments that are stick-shaped, such as ballpoint pens and pencils, are generally written while gripping them with three thumbs, an index finger and a middle finger. In the case of ballpoint pens, etc., when a long-time writing operation was performed, fatigue was accumulated on the fingertips, wrists, shoulders, etc., and as a result, illness such as neck-shoulder-arm syndrome was brought about.

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

[0004]

[Problems to be solved by the device]

 Therefore, the inventor of the present invention has a writing tool auxiliary tool and a ball-point pen in which a placing piece on which a fingertip is to be placed is projected outward in the vicinity of the tip of a base body fixed to the outer peripheral surface of the grip of the writing instrument. (See Japanese Patent Application No. 4-67853 and Japanese Patent Application No. 4-67854), but the position of the mounting piece is limited, so the way of holding the writing instrument differs depending on the individuality of the user such as right-handed or left-handed. Therefore, there is a problem in that it is not possible to sufficiently cope with these problems, and when used in a writing instrument such as a ballpoint pen, the tip ball is unevenly worn and cannot be used for a long period of time.

Therefore, in order to solve the above-mentioned problems, the inventor of the present invention uses a short tube mounted on the outer peripheral surface of the grip of the writing instrument so as to be slidable in the axial direction and rotatable in the circumferential direction. An auxiliary tool for a writing instrument in which a placing piece on which the fingertip of the index finger is to be placed is fixed to the grasping piece via a supporting piece so as to extend substantially parallel to the axial direction of the grasping portion at a predetermined interval (see Japanese Patent Application No. No. 19986), but stick-shaped writing instruments such as ballpoint pens and pencils are round or hexagonal depending on the type, and the shape and diameter of the gripping part such as size is slightly different, so that Naturally, there was a limit in using gripping pieces to support these writing instruments.

The present invention has been devised to solve the above-mentioned drawbacks, and is attached to the grip of a stick-shaped writing instrument such as a ball-point pen or pencil that has been commonly used in the past, so that the user's individuality can be improved. Efficiently use the power of the forefinger without being influenced by the movement of the forefinger. Writing with a light force and easy grip enable long-time writing without tiredness. The purpose of the present invention is to provide an auxiliary tool for writing instruments that can respond without being affected by the slight difference in the shape and size of the part.

[0007]

[Means for Solving the Problems]

 The present invention has been devised in view of the above, and is an auxiliary tool for a writing instrument that is attached to a grip of a stick-shaped writing instrument such as a ballpoint pen or a pencil. On the gripping piece made of a short tube that is slidably mounted on the gripping piece, the mounting piece made of a rectangular plate body on which the index finger is to be placed, is attached in the axial direction of the gripping part. On the other hand, the problem has been solved by allowing the tip of the placing piece to be fixed so as to be in close contact with the gripping portion by pushing the tip of the placing piece along the predetermined distance.

The gripping piece in the present invention is a piece that can be slidably and rotatably mounted on the gripping part of a writing instrument by elasticity, and has a circular tube-shaped short tube having elasticity slightly smaller than that of the gripping part. A short tube having a horseshoe-shaped cross section is used.

Next, as the placing piece in the present invention, one having a rectangular plate body which is formed so as to be along a grip portion of the writing instrument with a predetermined distance is used, and the back surface of the tip end portion thereof is used as the grasping part of the writing instrument. When the tip of the index finger is placed on this tip, the back surface of the tip is brought into close contact with or bonded to the grip of the writing instrument when the tip of the index finger is placed on the tip. For example, a means for fixing the gripping piece such that the gripping piece is located closer to the rear end side than the central portion in the longitudinal direction of the mounting piece is adopted.

It is preferable that both side surfaces of the tip side of the above-mentioned placing piece are inclined surfaces bent downward so as to ensure good placement of the fingertips during use. It is preferable that the surface of the placing piece on the tip end side is provided with a finely roughened portion so as to have a rough surface in order to improve the fit property to the fingertip.

Further, it is preferable that the tip portion of the placing piece is bent obliquely downward so that the force of the fingertip effectively acts on the tip portion of the writing instrument.

In addition, at least the tip side of the back surface of the above-mentioned placing piece has a better adhesion to the grip of the writing instrument, which is affected by a slight difference in size and shape of the grip of the writing instrument. A non-slip is provided so that it can be used without any action.For this anti-slip, sticking an elastic plate such as a rubber plate with a large frictional resistance to the back surface of the mounting piece or from a serrated cross section, etc. Is formed by roughening.

[0013]

[Action]

 The writing tool auxiliary tool of the present invention is a writing tool auxiliary tool that is attached to a grip of a stick-shaped writing tool such as a ballpoint pen or a pencil, and slides in the axial direction on the outer peripheral surface of the writing tool grip. A mounting piece consisting of a rectangular plate on which the index finger should be mounted is attached to a gripping piece consisting of a short tube that is mounted so as to be movable and rotatable in the circumferential direction, with respect to the axial direction of the gripping part. Since the tip of the placing piece is fixed so as to be in close contact with the gripping portion by the pressing force of the fingertip applied to the placing piece along the predetermined interval, the movement mainly with one forefinger That is, since the tip of the placing piece comes into close contact with the grip of the writing instrument due to the pressing force of the forefinger and causes the action of moving integrally with the writing instrument, it is attached without relying only on the clamping force of the grasping piece. In addition, the tip of the writing instrument does not lose most of the power of the index finger. It can be written while applying.
