Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a composite clip device for preventing a writing instrument from falling off from a writing instrument holding device.

(Prior art) Pencils, fountain pens, ballpoint pens, sharp pencils, drafting pens, felt-tip pens, markers, etc. (hereinafter referred to as writing implements), notebooks, notebooks, drawings, diaries, etc. (hereinafter referred to as notebooks), school bags, bags, handbags, etc., or writing implement cases, clothing. It would be extremely convenient if it was always attached and held in a pocket, etc. (hereinafter referred to as a storage device). For this reason, the above-mentioned notebooks and storage devices are provided with a writing instrument holding device (hereinafter referred to as a holding device) having a cylindrical shape having approximately the same diameter as the outer diameter of the shaft of the writing instrument, or a similar shape, and are widely used.

Now, some writing instruments have clips and others do not, but even for those with clips, the writing instrument may fall off from the holding device while being held, resulting in accidents such as breakage or loss of the writing instrument. It happens often.

More specifically, in the case of a clip that has a clip, the attachment part of the clip acts as a stopper in the direction toward the tip of the clip and does not fall off, but it tends to fall off in the opposite direction. This may be due to improper adjustment of the pressure force of the clip against the holding device that uses elasticity, elastic fatigue of the clip, a large gap between the inside diameter of the holding device and the outside diameter of the writing instrument, or even a decrease in strength due to repeated use of the holding device. This is because frictional force, binding force, etc. are reduced.

In addition, since there is no stopper in those without clips, they often move in any axial direction and fall off, so a countermeasure is needed.

(Problems to be solved by the invention) An attempt is made to provide a simple falling-off prevention device that can safely hold a writing instrument when it is inserted into the holding device and held in the conventional writing instrument holding device. It is something to do.

(Means for Solving Problems by Invention) This writing instrument consists of a clip body that can be fixed near one end of the writing instrument shaft, and a separate clip that is adjacent to the clip body and that can be attached to or removed from the shaft. , the clip body consists of a ring part that fits into the shaft body and a clip part that is integrated with the ring part, and the separate clip body also consists of a ring part that fits into the shaft body and a clip that is integral with the ring part. The clip main body and the separate clip parts can be integrally assembled with each other when the ring part is tightly fitted into the shaft body.

(Embodiment) Figures 1a and 1b show a first embodiment of the present invention. In FIG. 1a, 1 is the shaft of the writing instrument. 2 is a composite clip consisting of a clip main body 2a and a separate clip body 2b, each of which is molded from synthetic resin. Of course, metal alone or a composite molded product of metal, synthetic resin, rubber, etc. may also be used as long as it has the elasticity required for the clipping properties. In view of design diversity, such composite molding may be preferable. As shown in FIG. 1b, the clip main body 2a consists of a ring portion 3 that is tightly fitted to the shaft body 1, and a clip portion 4 that is molded integrally with the ring portion 3. Separate clip 2
It is provided with a groove portion 5 into which the clip portion 7 of b is fitted.

The separate clip body 2b also includes a ring portion 6 that fits tightly onto the shaft body 1, and a clip portion 7 that is molded integrally with the ring portion 6. The clip portion 7 has a protrusion 8 on its side surface, and correspondingly, a recess (not shown) is provided on the inner surface of the groove portion 5 of the clip portion 4 of the clip body 2a.

A positioning protrusion 10 is also provided on the inner surface of the ring portion 6, and correspondingly, a recess into which the protrusion 10 fits is provided in the shaft body 1, and the engagement between the protrusion and the recess allows the clip to be separated. Clip body 2b to body 2
It can be held on the shaft body 1 integrally with a.

Although not shown, the clip body 2a also has a protrusion for positioning on the inner surface of its ring portion 3, and a corresponding hole is provided in the shaft body 1 so that the clip body 2a can be positioned at a predetermined position on the shaft body 1 by engagement of the two. It is now possible to fix it. Note that the clip body 2a and the separate clip body 2
Since b is made of synthetic resin and has elasticity, it will be firmly held if it is tightly fitted, and the above-mentioned engagement structure of a convex portion and a concave portion is not necessarily required when fitting it to the shaft body 1.

With the above structure, the clip main body 2a and the separate clip body 2b are normally integrated as shown by the solid line in FIG. 1A, with their clip portions 4 and 7 engaged.

In this state, it can be used like a normal one-sided clip of a writing instrument, but as shown by the dotted line in Fig. (It can be easily removed by lifting the separate clip part slightly with your nails), insert it from the other end of the shaft body 1, and then
When the positioning protrusion 10 is engaged with a recess (not shown) provided at a predetermined position, the clip body 2
The clip portion 4 of the clip a and the clip portion 7 of the separate clip body 2b are now facing each other. In this state, the shaft body is attached to the cylindrical holding part of a notebook or bag.
is inserted, and the clip portions engage with both ends of the holding portion at both ends, thereby holding the shaft body 1 so as not to slip out in any direction.

FIG. 2 shows a second embodiment of the present invention. In this case, the clip main body 12a fitted near one end of the shaft 1 consists of a ring portion 13 and a clip portion 14 integral with the ring portion 13, as in the first embodiment. The separate clip body 12b is the same as the first example in that it consists of a ring part 16 and a clip part 17, but in this example, the clip part 17 is provided with an elongated hole 15 into which the clip part 14 of the clip main body 12a fits. It is being

FIG. 3 shows yet another embodiment, in which the clip main body 22a includes a ring portion 23 and a plate-shaped clip portion 24 integrated therewith.

In contrast, the clip separate body 22b has a ring portion 2.
6, and a plate-shaped clip portion 27 which is integrated with this and is superimposed on the clip portion 24. Since this clip portion 27 is superimposed on the plate-shaped clip portion 24 of the clip main body 22a, it is attached upwardly away from the ring portion 26 by that amount.

(Effect) A composite clip device consisting of a clip body and a separate clip body is attached to the shaft of a writing instrument, and if necessary, the separate clip body can be separated from the clip body and inserted and fixed from the other end of the shaft body. This allows the clips of the writing instrument to be engaged with both ends of the writing instrument holding device, thereby completely preventing the writing instrument from falling off.

Composite clips are also convenient because they can be manufactured and sold separately from writing instruments.
