Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument clip.

[0002]

2. Description of the Related Art A writing instrument, particularly a clip of a popular type of writing instrument mass-produced, is required to have a small number of parts, a simple structure, and a simple assembling operation. In addition, the clip is a large part that can be attached to the tail end surface of the cap or the barrel, and is a part that is easily seen when the writing implement is attached to a pocket or the like. In general, mass-produced popular writing instruments prefer simple beauty.

[0003]

However, conventional clips have not always fulfilled all of the above requirements. Therefore, an object of the present invention is to provide a writing instrument clip that has a small number of parts, has a simple structure, is easy to assemble, and has a simple beauty.

[0004]

In order to achieve the above object, a first aspect of the present invention is to provide a substantially U-shaped clip body, a pair of radially extending drawers connected to an upper end of the clip body, and a drawer. The upper annular portion and the lower annular portion connected to the portion are integrally formed by a single elastic metal wire, and the upper annular portion and the lower annular portion are formed on the outer peripheral surface of the cap or the barrel. Into each of the two annular grooves.

According to a second aspect of the present invention, in the first aspect of the present invention, the upper annular portion and the lower annular portion are formed in a C-shape, and two caps formed on the outer peripheral surface of the cap or the barrel. The annular groove is also C-shaped, and the ends of the upper annular portion and the lower annular portion are engaged with the edges of the annular groove to prevent the clip from rotating.

[0006]

Embodiments of the present invention will be specifically described below with reference to the drawings. FIGS. 1 to 4 show the first embodiment. When a writing instrument is attached to a pocket or the like, the lower end of the clip body 11 which presses against the fabric of the pocket is bent in an arc shape as shown in FIG. It has a long U-shape. As shown in FIG. 2, the side surface shape is curved in an arc shape, and when attached to the barrel 20, it comes into pressure contact with the outer peripheral surface of the barrel 20.

[0007] The upper end of the clip body 11 is connected to the radially extending portions 12, 12, respectively.
2 is connected to the upper annular portion 13 and the lower annular portion 14, respectively. As shown in FIG. 3, the end 13a of the upper annular portion 13 is located near the boundary between the upper annular portion 13 and the drawer portion 12, and the upper annular portion 13 has a substantially complete annular shape. The situation is the same for the lower annular portion 14, and the lower annular portion 14 is also almost completely annular.

[0008] The clip body 11, the drawers 12, 1
2, and the upper annular portion 13 and the lower annular portion 14 are integrally formed of a highly elastic metal wire, for example, a stainless wire having an outer diameter of 0.8 mm, and have a one-part structure and a structure. It is simple and extremely easy to manufacture.
And the shape of the clip is simple, giving it a simple beauty.

On the other hand, an upper annular groove 21 and a lower annular groove 22 corresponding to the upper annular portion 13 and the lower annular portion 14 are formed on the outer peripheral surface of the barrel 20 as shown in FIG. I have. Note that the barrel 20 may be a cap. Then, when assembling the clip to the barrel 20, the upper annular portion 13 and the lower annular portion 14 may be slightly expanded and fitted into the upper annular groove 21 and the lower annular groove 22. The upper annular portion 13 and the lower annular portion 14 fitted into the upper annular groove 21 and the lower annular groove 22 are tightly fixed by tightening the shaft cylinder 20 by its elasticity. And the assembling work is extremely simple.

FIGS. 5 and 6 show a second embodiment.
As shown in FIG. 5, the end 13 a of the upper annular portion 13 is located at a position away from the boundary between the upper annular portion 13 and the drawer portion 12, and has a C-shape instead of a complete annular shape. . Also,
The situation is the same for the lower annular portion 14, and it has a C-shape. Also, as shown in FIG. 6, the upper annular groove 21 and the lower annular groove 22 are not completely annular,
And the lower annular portion 14 has the same C-shape. The end 13a of the upper annular portion 13 engages with the edge 21a of the upper annular groove 21, and the end 14a of the lower annular portion 14 engages with the edge 22a of the lower annular groove 22. I have. Therefore, the second
According to the embodiment, the rotation of the clip can be completely prevented.

[0011]

As described above, the clip for a writing instrument of the present invention is connected to a substantially U-shaped clip body, a pair of radial drawers connected to the upper end of the clip body, and a drawer. The upper annular portion and the lower annular portion are integrally formed by a single elastic metal wire, and the upper annular portion and the lower annular portion are formed into two circles formed on the outer peripheral surface of a cap or a barrel. Each clip fits into the annular groove, so it is a one-part structure, the number of parts is small, the structure is simple, the assembling work is easy, and it has a simple beauty, and a clip suitable for popular writing instruments can do. The upper annular portion and the lower annular portion are formed in a C-shape, and two annular grooves formed on the outer peripheral surface of the cap or the shaft cylinder are also formed in the C-shape. When the end of the portion is engaged with the edge of the annular groove, the rotation of the clip can be completely prevented.
