Description

[Detailed Description of the Invention] The present invention relates to a writing instrument clip, and more particularly to a writing instrument clip using a linear body.

The tip of a writing instrument clip weighs between 30g and 70g.
It is preferable for use to use a device that is attached so as to be pressed against the shaft cylinder or cap with a certain amount of force (hereinafter referred to as initial load), and it is said to be more optimal that this initial load can be maintained for a long period of time. Therefore, a clip in which this initial load decreases as it is used, or in other words, the clip becomes flattened, floats, or bends outward, is unsuitable as a writing instrument clip.

Considering a writing instrument clip made of a linear body made of metal, hard resin, etc., if the clip size is made a certain length, elasticity corresponding to the length can be obtained even if the cross-sectional area is large. Decrease in initial load can also be avoided with appropriate rigidity and elasticity, but if the clip dimensions must be made relatively short due to design restrictions, etc.
With a cross-sectional area similar to the above, elasticity is not obtained, and the rigidity increases, making it feel very hard to use, and the attachment part may be damaged if used repeatedly or when thick objects are pinched. The problem of putting it away arises. Also, if the cross-sectional area is made small so that appropriate elasticity can be obtained even if the clip size is short, the rigidity will be inferior, so the clip will bend when used repeatedly or when holding thick objects. A problem arises.

In this way, when a linear body made of metal, hard resin, etc. is used as the clip, and the clip size is short, a writing instrument clip that satisfies appropriate rigidity and elasticity and can maintain the initial load for a long period of time can be obtained. This was very difficult for me.

This idea was created in view of the problems mentioned above.
By using a linear body as a writing instrument clip, the present invention aims to provide a writing instrument clip that satisfies appropriate rigidity and elasticity and can maintain an initial load for a long period of time by devising its form. .

The present invention will be described in detail below based on embodiments shown in the accompanying drawings. The drawings show an example in which the present invention is applied to a cap of a cap-sliding type mechanical pencil.

In FIGS. 1 and 2, reference numeral 1 indicates iron;
It is a linear body made of metal such as brass, stainless steel, hard resin such as ABS resin, etc. In the illustrated example, one with a circular cross-sectional shape is shown, but a polygonal one may also be adopted. . A spiral body 2 made of metal, resin, etc. is integrally fixed to the outer periphery of the linear body 1 by pressure bonding, adhesive, etc., and the linear body 1 and the spiral body 2 constitute a clip 3. An example of how to assemble the above-mentioned clip 3 is that the linear body 1 is press-fitted into the spiral body 2 having an inner diameter slightly smaller than the diameter of the linear body 1. 4 is a metal having two stages of holes 7: a linear body attachment hole 5 and a spiral body attachment hole 6;
It is a chip made of resin or the like. Incidentally, the tip 4 is not necessarily necessary, as it can be substituted by forming the linear body 1 and the spiral body 2 by bending, etc., or by forming a protrusion in place of this on the shaft cylinder or the surface of the cap. 8 is a clip attachment part provided in the cap 9, which includes a linear body attachment hole 10 and a spiral body attachment hole 1.
1 and two stages of holes 12. To attach the clip 3, as shown in FIG. 2, the ends of the linear body 1 protruding from both ends of the spiral body 2 are press-fitted into the tip 4 and the linear body attachment holes 5, 10 of the clip attachment part 8 and fixed. , by inserting the ends of the spiral body 2 into the spiral body mounting holes 6 and 11 of the chip 4 and the clip attachment part 8, or by inserting the ends of the linear body 1 and the spiral body 2 into the spiral body mounting holes 6 and 10 of both spiral bodies. It can be fixed by press-fitting, or as shown in FIG. Single hole 7,1
The helical body 2 may be fixed and attached to the helical body 1 by press-fitting or screwing.

FIG. 4 shows another embodiment of the present invention, in which a clip 3 with a spiral body 2 fixed to a linear body 1 is bent at the center, and the end of the bent clip 3 is attached to a clip attachment part 8. It is attached to.

In the above-mentioned embodiments, the spiral body 2 is fixed to the linear body 1 by pressure bonding, adhesive, etc., but the spiral body 2 may not be in a fixed state but may be in a loosely fitted state. .

As is clear from the above explanation, in this invention,
The spiral body 2 is wound around the outer periphery of the linear body 1 to form a clip 3, and the end of the clip 3 is fixed to the clip attachment part 8, so even if the clip size is short, Due to the synergy between the linear body and the spiral body, it is possible to provide a writing instrument clip which has appropriate rigidity and elasticity and can maintain an initial load for a long period of time.
