Field of technology

TECHNICAL FIELD This invention relates to the grip for writing instruments used, for example, attached to the shaft body of writing instruments, such as a pencil and a ballpoint pen.

Prior art

In a conventional writing instrument grip, only the cushion elastic body is configured as a cylindrical elastic grip main body, since the cushion effect when it is attached to the shaft body of the writing instrument is based on the elastic action as much as the thickness of the elastic grip main body. Thus, it was not possible to expect a sufficient effect to surely prevent the occurrence of calluses on the fingers holding the pen holder.

For this reason, as shown in FIG. 6, in the inner peripheral surface 02a of the cylindrical elastic grip main body 02 which comprises the grip 01 for writing instruments, many groove-shaped parts 03 are circumferential direction of a longitudinal direction. It is known that the cushioning effect at the time of mounting and using, for example, a hexagonal cross section hexagonal writing instrument (not shown) by using a cross section hexagon in order to improve it is used (refer patent document 1).

However, in the above-described Patent Document 1, when the elastic grip main body 02 is mounted on the writing instrument, the concave portion 03 formed on the inner circumferential surface 02a is continuous in both the longitudinal direction and the circumferential direction. Therefore, when the writing instrument is inserted into the elastic grip main body 02, it is difficult to insert the writing instrument.

In addition, if the writing instrument is of an angular axis type, a gap is formed between each side surface of which the angular axis is flat and the concave portion 03 opposite thereto, whereby the adhesion is low and it is difficult to perform stable writing. .

Moreover, in order to make it easier to insert a writing instrument in the elastic grip main body 02, when the inner diameter of the elastic grip main body 02 is enlarged, the adhesiveness to a writing instrument becomes further low, and there exists a problem that stable writing cannot be performed.

Patent Document 1: Publication No. 54-128539

In view of the above problems with the prior art, the present invention facilitates the insertion of writing instruments, increases the cushioning effect, prevents the occurrence of calluses on the fingers of the pen holders, and It is an object of the present invention to provide a grip for a writing instrument which increases the adhesion of the writing and enables stable writing.

According to this invention, the said subject is solved as follows.

(1) A grip provided with a cylindrical elastic grip main body attached to a shaft of a writing instrument, wherein a large number of independent small protrusions are scattered on the inner circumferential surface of the elastic grip main body.

(2) In the above (1), the independent small protrusions are formed almost in a hemispherical shape, and are dotted so as to face each flat side surface of the angular writing instrument and to be arranged in the longitudinal direction of the elastic grip main body.

(3) In the above (2), the independent protrusions are disposed so as to face each of the flat side surfaces of the hexagonal axis writing instrument so as to be arranged in the longitudinal direction.

(4) In the above (2) or (3), during use of the writing instrument, the elastic grip main body deforms by pressing from the fingertip loaded on the grip, so as to face each flat side of the angular writing instrument. In addition, the independent small protrusions interspersed so as to be arranged in the longitudinal direction of the elastic grip main body are elastically deformed to adhere to the respective flat side surfaces.

(5) The hand piece according to any one of the above (1) to (4), which can be held by the thumb and forefinger of the hand on the outer surface of the elastic grip body during use of the writing instrument. Stand up)

(6) In any one of said (1)-(5), the inner diameter of an elastic grip main body is made into a small diameter gradually toward the other end from one end.

EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment of this invention is described in detail with reference to drawings. 1 is a perspective view showing a writing state by a pencil equipped with a writing instrument grip according to an embodiment of the present invention, FIG. 2 is an enlarged perspective view of a writing instrument grip, FIG. 3 is a front view of the writing instrument grip similarly. Fig. 3 is a longitudinal sectional view taken along the line IV-IV of Fig. 3, and Fig. 5 is a longitudinal front view showing the clamping state of the grip pieces.

As shown in Fig. 1 and Fig. 2, the writing instrument grip 1 of the present invention is an angular writing instrument, for example, an elastic grip body such as a cylindrical rubber mounted on the shaft of the hexagonal pencil P. (2) is provided. On the inner circumferential surface 2a of the elastic grip main body 2, a number of independent small protrusions 3 are interspersed and formed.

As shown in Figs. 3 and 4, each of the independent protrusions 3 is formed in a substantially hemispherical shape, and the elastic grip body is opposed to each of the flat side surfaces 4 of the hexagonal axis pencil P. It is arranged along the longitudinal direction of (2).

On the outer side surface 2b of the elastic grip main body 2, the grasping piece 5 stands up along the longitudinal direction of the elastic grip main body 2, and is formed. As shown in Figs. 1 and 5, the grip piece 5 can be held by the thumb and forefinger of the hand. During use of the pencil P, as shown by the broken line in FIG. 5, the elastic grip main body 2 deforms by pressing from the fingertip loaded on the grip 1 for writing instruments, and the hexagonal axis pencil P The independent small protrusions 3 arranged in the longitudinal direction so as to face each of the flat side surfaces 4 of each other are in close contact with the flat side surfaces 4.

In addition, in this embodiment, although the inner diameter of the elastic grip main body was made constant, the inner diameter of an elastic grip main body can also be made into a small diameter gradually toward the other end from one end.

In addition, although the pencil P was demonstrated as an example as an angular writing implement, it is applicable also to a ballpoint pen.

According to the present invention, the following effects can be achieved.

According to the invention as set forth in claim 1, since a large number of independent protrusions are interspersed on the inner circumferential surface of the elastic grip body, the insertion of writing instruments is easy because each independent protrusions are independent and do not continue in the longitudinal direction. I can do it. In addition, each of the independent protrusions independently acts elastically, increases the cushioning effect, prevents the occurrence of calluses generated on the fingers of the pen holder, and increases the adhesion to the writing instrument, thereby enabling stable writing.

According to the invention as set forth in claim 2, since the independent protrusions are formed in a nearly hemispherical shape and are arranged so as to be arranged in the longitudinal direction of the elastic grip main body to face each flat side surface of the angular writing instrument, It is possible to increase the adhesion to each of the flat side of the.

According to the invention described in claim 3, since the angular writing instrument is a hexagonal axis, the adhesion to each of the flat side surfaces of the writing instrument can be increased, and stable writing can be performed.

According to the invention according to claim 4, since the independent protrusions are elastically deformed and brought into close contact with the flat side surfaces of the angular writing instruments, the deviation of the shaft can be reliably prevented and stable writing can be performed.

According to the invention according to claim 5, since the rat which can be held by the thumb and forefinger of the hand stands on the outer surface of the elastic grip main body, the writing instrument can be stably held with a small fixing force. It is possible to prevent the occurrence of callus generated on the finger holding the pen stand, and to perform stable writing, and to prevent the cloud when the writing instrument is placed on a table or the like.

According to invention of Claim 6, since the inner diameter of an elastic grip main body is larger, it can attach easily by attaching to the shaft of a writing instrument, and the positional stability of the writing instrument grip after mounting is also favorable.
