JPH07476A - Writing tool having therapeutic ball and its manufacture - Google Patents

Abstract

PURPOSE:To provide a novel writing tool having a ball and manufacture thereof, which enables not only functioning thereof as writing tool but also the use thereof as meridian point treatment device for stimulating the meridian points such as head, face, hands and the like when a user feels fatigued during working in offices or studying thereby enabling to use thereof with caution without losing it and without wasting natural resorces. CONSTITUTION:A rim undergoes a drawing work at a large-diameter part 3 of a ball holding cylinder 1 comprising a two-stage cylinder body a roughly half of which is smaller in diameter while the other half is larger in diameter. A ball body is held in the large-diameter part 3 free to rotate and a base end part of the writing tool is fitted into the small-diameter part 2. A part of the ball body 5 is made to stick out of the rim drawn of the large-diameter part 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument such as a ballpoint pen, a mechanical pencil, a fountain pen having a sphere attached to its base end, and a method for producing the same.

[0002]

2. Description of the Related Art In conventional writing instruments such as ballpoint pens,
It is publicly known that a decoration is attached to its base end.

[0003]

SUMMARY OF THE INVENTION In a conventionally known writing instrument with an ornament, since the ornament was merely attached for decoration, the value of the writing instrument was not particularly increased by this. On the other hand, ordinary ball-point pens that are generally used have a strong sense of being disposable, and if the ink is used up, the whole is thrown away, and even if the ink is not used up, pay particular attention to the loss. Nor. As a result, there is a problem that the limited resources are wasted.

The present invention has been made in view of the problems of the above-described previously known writing instruments, and has not only the function as a writing instrument but also the head, face,
It can be used as an acupoint therapy tool that stimulates acupoints on the hands, etc. Therefore, it is hoped that it will be used carefully so that it will not be lost, etc., and as a result, a novel writing instrument with a ball and a manufacturing method thereof will be provided The purpose is to

[0005]

In order to solve the above problems, the writing instrument with a sphere of the present invention has a large diameter of a sphere holding cylinder composed of a two-stage cylindrical body having a small diameter in approximately half and a large diameter in the other half. The edge of the part is drawn, the sphere is rotatably held in this large diameter part, the base end of the writing instrument is fitted to the small diameter part, and part of the sphere is drawn on the large diameter part. It is characterized in that it is configured so as to protrude from the formed edge. It is desirable that the sphere be a lens. Further, the method for producing a writing instrument with a sphere according to the present invention comprises: receiving a sphere in the large diameter portion of a sphere holding cylinder made of a two-stage cylindrical body having a half of the small diameter and the other half of the large diameter, and then the large diameter. The sphere is rotatably held in the large diameter part by drawing the edge of the part, and then the base end of the writing instrument is fitted to the small diameter part, and part of the sphere is drawn in the large diameter part. It is characterized in that it is made to project from the edge.

[0006]

The details of the present invention will be described with reference to the embodiments shown in the drawings. In the figure, reference numeral 1 is a sphere holding cylinder made of a two-stage cylindrical body, and approximately half of the sphere holding cylinder has a small diameter to be a small diameter portion 2, and the other half has a large diameter portion 3. The edge of the large diameter portion 3 is drawn to form a drawn edge 4, and the sphere 5 is held in the large diameter portion 3 to prevent the sphere 5 from popping out or coming off and held. is there. The sphere 5 is a crystal ball that is effective in exerting crystal power, but may be another sphere such as a pearl ball, a glass ball, or a steel ball.

Reference numeral 6 in the drawing is a writing instrument, and the one shown is a ball-point pen. The base end portion 7 of the writing instrument 6 is fitted into the small diameter portion 2 of the sphere holding cylinder 1, the sphere body 5 is pushed by the base end portion 7, and a part of the sphere body 5 has a large diameter as shown in FIG. It is projected from the drawing edge 4 of the portion 3. In the embodiment shown in the drawings, the base end portion 7 has a diameter slightly smaller than that of the main body of the writing instrument 6. Further, although a ball-point pen is shown as the writing instrument in the embodiment shown in the drawings, this writing instrument may be another one such as a pencil or a fountain pen.

Next, a method for manufacturing the writing instrument with a ball of the present invention will be described. First, as shown in FIG. 2, the small diameter portion 2 whose edge is not drawn.
And a sphere holding cylinder 1 consisting of a two-stage cylindrical body having a large diameter portion 3 and
A sphere 5 is received in the large diameter portion 3. After that, as shown in FIG. 3, the edge of the large-diameter portion 3 is drawn to form a drawn edge 4, which holds the sphere 5 so as not to jump out. In this state, a part of the sphere 5 has a drawing edge 4 of the large diameter portion 3.
Although it may be configured to project slightly, the sphere 5 does not project from the drawing edge 4 in the illustrated embodiment.
Therefore, next, the base end portion 7 of the writing instrument 6 is connected to the small diameter portion 2 of the ball holding cylinder 1.
The sphere 5 is drawn by the base end portion 7
It is designed to be pushed out and projected.

[0009]

The writing instrument of the present invention having such a structure not only exhibits the original function as a writing instrument, but also the sphere attached to the base end of the writing instrument can be freely rotated. It is preferable that the finger is stimulated by rotating. Also, when you feel tired during office work as a job or during study, you can stimulate the acupoint by pressing this sphere against the acupoints such as your face to perform fatigue recovery therapy, and the sphere can rotate. Acupoint treatment can be performed while searching for acupoints. And especially when the sphere is a crystal ball, it is more effective by the crystal power.

Further, according to the present invention, since it has the above-described action, its value as a writing instrument is increased, and if it is a ball-point pen, the ink will be used up sufficiently so that the ink will be consumed. Attach a replacement core and start using it again. Also,
Since it also takes care not to lose it, the limited waste of resources is eliminated, which is an effective effect for effective use of resources.
