Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a finger support for a writing implement that enables writing with a writing implement such as a ball-point pen even when the gripping force of the fingertip is weak.

[0002]

[Prior art]

 Normally, when writing with a writing instrument such as a ballpoint pen for a long time, fingers, hands, wrists, etc., become tired. In particular, when the writing pressure is high, the gripping force of the writing instrument is strong, and the person becomes tired relatively quickly.

[0003] Furthermore, when the gripping force of the fingertips is weakened due to illness or obstacle, it is often difficult to write with a writing instrument in the same state as a healthy person.

[0004]

[Problems to be solved by the invention]

 By the way, several types of writing implements have been conventionally devised. For example, Japanese Patent Application Laid-Open No. H10-86587 discloses a holder in which a large ring made of an elastic body and a small ring made of an elastic body are integrally fixed via a connecting portion. I have.

[0005] This holding tool inserts and supports the pen on the small ring side such that the tip of the pen is on the rear side, and inserts and supports the large ring side on the middle finger. The pen supported on the back side is rotated as if hooked by a thumb, and the pen is gripped with a thumb and an index finger so that writing can be performed. The above-mentioned holding tool is convenient because the writing tool does not have to be picked up from a desk when operating a keyboard such as a personal computer or a word processor.

However, it is not intended to supplement the gripping force of the finger from the beginning. Especially, since the large ring is inserted into the middle finger, it is difficult to use the finger when the gripping force of the index finger is weak. .

[0007]

[Purpose of the invention]

 The present invention has been made in order to solve the above-described problems, and it is possible to write even if the gripping force of the finger is weak, and it is also possible to suppress the occurrence of a pen, so that the hand, finger, etc. It is an object of the present invention to provide a finger support for a writing instrument that can reduce fatigue.

[0008]

[Means for Solving the Problems]

 The finger support for a writing implement of the present invention includes a first tapered cylindrical body that supports a writing implement such as a ballpoint pen that is slit in the outer peripheral direction and a second tapered cylindrical body that is also inserted in the outer peripheral direction. The first tapered cylindrical body has a second taper through a contact portion so that the center axes of the two cylindrical bodies are parallel to each other and the angle between the center axes of the two cylindrical bodies can be adjusted. Characterized by being attached to a cylindrical shape.

An embodiment of the present invention will be described below with reference to the drawings.

[0010]

【Example】

 FIG. 1 is an external view showing the use state of the finger support for a writing implement of the present invention, and FIG. 2 is an external view of the finger support for a writing implement of the present invention before being attached to a finger. In these figures, numeral 1 indicates the entire finger support for the writing implement. This finger support 1 for a writing implement has a first tapered cylindrical body 2 for inserting and supporting a writing implement 4 such as a ball-point pen, and a second tapered cylindrical body 3 for inserting and supporting the index finger on the index finger 5. . As shown in FIG. 3, the first tapered cylindrical body 2 has a second tapered cylindrical shape so that the angle θ (see FIG. 2) between the center axes C1 and C2 in the horizontal plane can be adjusted. It is attached to a substantially central position on the outer periphery of the body 3 via the connection portion 6.

The connecting portion 6 has a shaft portion 6 a protruding from a substantially central position on the outer periphery of the first tapered cylindrical body 2, and an enlarged head portion 6 b formed at a tip of the shaft portion 6 a. As shown in FIG. 6, a gear-shaped uneven portion 7 is formed on the outer periphery of the enlarged head 6b.

On the other hand, a hole 8 (see FIG. 3) to which the enlarged head 6b is fixed is provided substantially at the center of the outer periphery of the second tapered cylindrical body 3. On the inner periphery of the hole 8, irregularities (not shown) corresponding to the irregularities 7 formed on the outer periphery of the enlarged head 6b are formed at the same pitch so as to mesh with each other.

The above-mentioned cylinders 2 and 3 are preferably formed of a hard rubber material having appropriate elasticity. However, since the slits 2a and 2b are provided in the outer peripheral longitudinal direction of the cylinders 2 and 3, the cylinders 2 and 3 are formed in half. The diameter can be increased in the radial direction, and it may be formed of another material such as plastic or metal.

When the cylinders 2 and 3 are formed of a material other than rubber and the cylinders 2 and 3 themselves have poor elasticity, as shown in FIG. A through hole 9 may be provided substantially at the center of the outer periphery on the side of the cylindrical body 3, and a rubber receiving plate 10 having an inner surface with irregularities 10 a may be interposed in the through hole 9.

With this configuration, the inclination angle θ of the first tapered cylindrical body 2 with respect to the first cylindrical body 3 can be arbitrarily changed as shown in FIG. . That is, the angle of the writing implement 4 with respect to the writing surface can be adjusted.

On the inner surface of the first tapered cylindrical body 2 for holding the writing implement 4, fine irregularities 11 are formed in the axial direction, and the concave portions of the irregularities 11 are formed, for example, on the outer surface of a ballpoint pen. It engages with the polygonal projections and serves to prevent rotation in the circumferential direction.

A large number of projections 12 are formed on the inner surface of the second tapered cylindrical body 3 so as to play a role of preventing slippage when the second cylindrical body 3 is attached to the index finger 5. Further, although not shown, the cylindrical body 3 may be provided with a large number of through-holes on its outer periphery to improve the air permeability and prevent the fingers from getting stuffy.

Next, a method of using the writing instrument finger support 1 configured as described above will be described. First, a writing instrument 4 such as a ball-point pen is inserted and fixed to the first tapered cylindrical body 2 from its enlarged end to its reduced end. In this case, even if there is a certain difference in the outer diameter of the writing implement 4, the writing implement 4 can be smoothly inserted because the inner surface is tapered. Further, since the tapered cylindrical body 2 is formed with a slit in the longitudinal direction, the diameter can be increased in the outer peripheral direction, and the writing instrument 4 having a large outer diameter can be fixed.

Next, as shown in FIG. 1, the second tapered cylindrical body 3 is inserted into the index finger 5 and fixed near the second joint. In such a case, the thickness of the finger varies depending on each person. However, since the slit 3a is formed in the vertical direction of the cylindrical body 3, the diameter can be increased in the outer peripheral direction, and the finger of each person can be enlarged. It can correspond to the thickness.

Next, the thumb may be lightly applied to the outer periphery of the first tapered cylindrical body 2 to perform writing. In this case, if the user does not have a desired feeling of stability or familiarity with the finger, the first tapered cylindrical body 2 is rotated to adjust the inclination angle θ.

After the above adjustment, the thumb 13 is lightly applied to the outer periphery of the first tapered cylindrical body 2, and writing is started so that the tip of the index finger 5 is attached to the writing implement 4. In this case, since the writing implement 4 is supported by the first tapered cylindrical body 2 and the second tapered cylindrical body 3, the writing implement 4 is strongly held by the tip of the index finger 5 and the tip of the thumb 13. There is no need to grip.

[0022] Therefore, writing can be performed even when the gripping force of the finger is weak, and it is possible to prevent the pen from being swung, thereby minimizing fatigue of the hand, finger, and the like due to writing. In the above embodiment, the first tapered cylindrical body 2 and the second tapered cylindrical body 3 are illustrated as having different lengths. However, the present invention is not limited to such a figure, and may have the same length. The second tapered cylindrical body 3 may be longer than the first tapered cylindrical body 2. Even if the cylindrical bodies 2 and 3 are not tapered and are straight cylinders, the same effects as those of the present invention can be obtained without departing from the basic technical idea of the present invention.

[0023]

[Effect of the invention]

 The present invention has a first tapered cylindrical body that supports a writing instrument and a second tapered cylindrical body that is inserted into an index finger, and is connected via a connecting portion so that the angle between them can be adjusted. Therefore, the writing implement can be grasped in accordance with the foot feeling of each person. In addition, since the writing instrument is supported by the cylindrical bodies, it is possible to write even when the gripping force of the finger is weak, and it is also possible to suppress writing with a pen and significantly reduce hand and finger fatigue caused by writing. There are excellent effects such as being able to.
