Problems solved by technology

[0004] However, in the grip described in the above-mentioned patent document 1, when the elastic grip body (02) is installed on the writing tool, the groove-shaped portion (03) formed on the inner peripheral surface (02a) is in the longitudinal direction and the circumferential direction. The two directions are continuous, so when inserting the note tool into the elastic grip body (02), the note tool is not easy to insert
[0005] Moreover, when the writing tool is a corner shaft type, there will be looseness in the gap between the flat sides of the corner shaft and the groove-shaped portion (03) facing it, and the degree of coherence will be reduced and it will be difficult to carry out stable writing.
[0006] In addition, when the inner diameter of the elastic grip body (02) is increased in order to easily insert the writing tool into the elastic grip body (02), there is a problem that the degree of closeness to the writing tool is further reduced, and stable writing cannot be performed.

Embodiment Construction

[0029] Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing the state of writing of a pencil with a pen grip for a writing tool according to an embodiment of the present invention, Fig. 2 is an enlarged perspective view of a writing tool with a pen grip, and Fig. 3 is a front view of a writing tool with a pen grip, Fig. 4 is a longitudinal sectional view taken along line IV-IV in FIG. 3 , and FIG. 5 is a longitudinal sectional front view showing the gripping state of the grip piece.

[0030] As shown in Fig. 1 and Fig. 2, the pen grip (1) of the writing instrument of the present invention has the elastic pen grip main body (2) of cylindrical rubber etc. on the shaft of the pencil (P). A plurality of independent small protrusions (3) are scattered and formed on the inner peripheral surface (2a) of the elastic grip main body (2).

[0031] As shown in Figures 3 and 4, each independe...

Abstract

The present invention provides a grip for note instrument which makes the insert of the note instrument easy, prevent fingers from growing pen cocoon as well as increases the cling degree with the note instrument so as to note stably. The grip pieces possesses cylinder-shape springy grip main body(2)installing on the axis of the note instrument(p),and makes many small independent warts(3)intersperses on the internal circle surface(2a) of the given spring grip main body(2).

Description

technical field [0001] The present invention relates to a grip (grip) for a writing tool, for example, installed on a shaft of a writing tool such as a pencil or a ballpoint pen for use. Background technique [0002] In existing pen grips for writing tools, only the cylindrical elastic grip main body constitutes the grip, and the cushioning effect when it is installed on the shaft body of the writing tool and used is only based on the thickness of the elastic grip main body. Because of the elastic effect, the cushioning is not enough, and a sufficient effect cannot be expected to reliably prevent the generation of finger calluses. [0003] Therefore, it is known that, as shown in FIG. 6 , on the inner peripheral surface (02a) of the cylindrical elastic grip main body (02) constituting the writing tool grip (01), continuous A plurality of groove-shaped parts (03) are formed in such a way that, for example, when the cross-section is a hexagonal shaft-type writing implement (n...
