Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a writing pen with a clip or a cosmetic pen (hereinafter collectively referred to as “pen”).
[0002]
[Prior art]
In a pen, it is often engaged with the upper end of a pocket of clothes through a clip, but in order to realize the engagement, the clip is in a state where it is joined at the root portion with a spring that is pressed inside the pen shaft. is there.
[0003]
The joint between the clip and the spring is inserted through the long hole of the pen shaft, but the spring is fixed inside the pen shaft in order to prevent the spring from moving in the left / right and front / rear directions. However, for the fixing, for example, a complicated technical means such as welding is adopted, which is extremely complicated in manufacturing.
[0004]
In addition, such manufacturing complexity is inevitable to be reflected in the cost of the clip-attached pen.
[0005]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to overcome the above-mentioned drawbacks of a pen having a clip and to provide a pen with a clip having a configuration in which a spring can be easily attached to the inside of a pen shaft. .
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the configuration of the present invention is as follows.
(1) Inserting the joint portion between the clip located outside the pen shaft and the spring located inside the pen shaft through the long hole of the pen shaft without sticking to the pen shaft, In a pen with a clip in which a spring provided with a protrusion provided at or near the tip of a small hole or recess in the pen shaft presses the pen shaft elastically, the middle part of the spring is A pen with a clip based on the fact that it is provided with a substantially square-shaped bent-shaped protrusion on the side, and is fitted into a small hole or recess of the pen shaft at a position corresponding to the top of the bent shape,
(2) Inserting the joint between the clip located outside the pen shaft and the spring located inside the pen shaft through the long hole of the pen shaft in a state where it is not fixed to the pen shaft, In a pen with a clip in which a spring provided with a protrusion provided at or near the tip of a small hole or recess in the pen shaft presses the pen shaft elastically, at or near the tip of the clip By adopting a design that does not have a protrusion on the pen shaft side, the inner surface of the clip and the outer surface of the pen shaft are in contact with each other, and when the joint with the spring is pressed toward the pen shaft, A clip-attached pen based on the fact that the joint portion fits into the pen shaft side through a long hole and the tip end side of the clip can be separated from the pen shaft;
Consists of.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows the basic configuration of the above (1) . The spring 2 that elastically presses the pen shaft 3 is provided with a protrusion on the tip or near the tip. It has a basic feature in that it is attached to the pen shaft 3 by being fitted into the small hole or recess 32.
[0008]
The pen shaft 3 can be both a pen shaft body and a cap.
[0009]
FIG. 1A shows a case where a protrusion is provided at the tip of the spring 2 and a protrusion having a substantially U-shaped bent shape is provided in the middle of the spring 2 and the top of the bent shape is fitted in the small hole. FIG. 1 (b) shows a case where protrusions having a substantially square-shaped bent shape are provided in the vicinity of the tip of the spring 2 and in the middle of the spring 2 and the top of the bent shape is fitted in the recess.
[0010]
In the case of the embodiment shown in FIGS. 1 (a) and 1 (b) , the pen shaft 3 is firmly connected to the pen shaft 3 by inserting the pen shaft 3 into the small holes or the recesses 32. It has features in terms of points.
[0011]
FIG. 2 shows the basic configuration of the above (2), but a protrusion (usually called a “ball”) facing the surface side of the pen shaft 3 is usually provided at the tip of the clip 1. There are many cases.
[ 0012 ]
In the basic configuration (2), as shown in FIG. 2A , the clip 1 is not provided with the protrusion, and the inner surface of the clip 1 is in contact with the outer surface of the pen shaft 3. It has the characteristics.
[ 0013 ]
With such a design, in the case of the basic configuration (2), it is possible to realize an extremely compact and smart design of a clip pen.
[ 0014 ]
And in this invention, since the junction part of the clip 1 and the spring 2 is not adhering to the pen axis | shaft 3, but it is in the insertion state to the long hole 31 of the pen axis | shaft 3, as shown in FIG.2 (b), When the clip 1 is engaged with the upper end of the pocket or the like, when the joint portion of the clip 1 with the spring 2 is pressed to the inside of the pen shaft 3, the clip 1 has the tip of the elongated hole 31 as a central axis. As a result, partial rotation is performed, and the tip portion is separated from the pen shaft 3.
[ 0015 ]
That is, in the case of the basic configuration (2) , the above-described compact and smart design is realized, and the tip portion of the clip 1 is separated from the pen shaft 3 as described above. Engagement with pockets can also be realized.
[ 0016 ]
Thus, in the present invention based on the basic configurations (1) and (2), the protrusion located at or near the tip of the spring 2 is fitted into the small hole or recess 32 of the pen shaft 3, and The clip 1 can be attached to the pen shaft 3 by a very simple configuration in which the joint between the clip 1 and the spring 2 is inserted into the long hole 31 of the pen shaft 3 without being fixed to the pen shaft 3. Thus, the structural complexity as in the prior art can be avoided.
[ 0017 ]
Hereinafter, description will be made with reference to examples.
[0018]
[ Example ]
Usually, when the clip 1 and the spring 2 are attached to the pen shaft 3, they are often joined using screws or the like, but the joining often involves complicated work.
[0019]
In the embodiment , based on the configuration of the above (1), as shown in FIGS. 3A, 3B and 3C , the clip 1 and the spring 2 are integrally formed in advance, and the spring 2 is The clip 1 and the clip 1 are sequentially inserted from the distal end portion into the distal end side of the pen shaft 3 through the long hole 31 until the distal end of the spring 2 or a protruding portion in the vicinity thereof fits into the small hole or the recessed portion 32 of the pen shaft 3. By moving the spring 2 toward the tip end side of the pen shaft 3 (actually, it is often accompanied by a slide), the joint portion between the clip 1 and the spring 2 is inserted into the long hole 31.
[0020]
Such a series of integral formations makes it very easy to join the clip 1 and the spring 2 and to attach to the pen shaft 3, and the embodiment can be solved in that the complicated work as in the prior art can be solved. It has a periodical significance.
[0021]
【The invention's effect】
As described above, the present invention makes it possible to attach the clip and the spring to the pen shaft very easily as compared with the prior art. In particular , in the case of the basic configuration (2) , the present invention is compact and smart. In the case of the embodiment, the attachment of the clip and the spring to the pen shaft is extremely simple.
[0022]
Thus, the present invention has a multifaceted value, and the value is tremendous.
