Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a flat multicolor ballpoint pen.

Conventional technology and its problems Conventional multicolor ballpoint pens store multicolored ballpoint pens in one barrel, and when writing, the ballpoint pen of the selected color protrudes from the opening at one end of the barrel, and the ballpoint pen of the selected color protrudes from the opening at both ends of the barrel. Some were equipped with two-color ballpoint pens for writing with the cap removed, and others had multiple ballpoint pens inserted into a common cap.

However, all of these products have a relatively thick cylindrical shape, so while they are good for carrying around by storing them in a pencil case or bag, they feel uncomfortable if they are stored in the inside pocket of clothes, There were inconveniences such as not being able to store it in the case.

Purpose of the invention The present invention is a multicolored ballpoint pen that can be used as a single card when not being used for writing, and can be inserted into an inner pocket of clothing or stored in a wallet, card holder, etc.

Summary of the invention In order to achieve the above-mentioned purpose, the invention includes a flat body having a circular hole, a rotating member rotatably inserted into the circular hole, and a ballpoint pen protruding from the tip.
It consists of a plurality of sliders that are movably engaged in the radial direction of a rotating member, and the main body has a guide groove in which the sliders can be inserted continuously into a circular hole until the ballpoint pen protrudes from the end surface of the main body. It has the structure of a multicolored ballpoint pen.

Therefore, when the slider of each color ballpoint pen engaged with the rotating member rotates to the guide groove, it can be inserted into the guide groove and the ballpoint pen can be protruded from the main body. Write while holding down. When you have finished writing and want to store the ballpoint pen, move the slider from the guide groove into the rotating member, and when it rotates to the point where neither slider can be inserted into the guide groove, the slider will be retained in the circular hole of the main body. Therefore, it can be stored in a wallet or card case along with other cards, or it can be carried as is in an inner pocket of clothing.

Note that if the slider is constantly pushed outward by a spring, the slider of the desired color can be simply rotated to the guide groove, and the slider is automatically inserted into the guide groove and the ballpoint pen is inserted. It protrudes, making it easier to operate. Furthermore, by providing a locking device (such as a hook) for locking the slider inserted into the guide groove, it is possible to write without holding down the slider.

Example Embodiments of the invention are explained in the drawings.

A rectangular flat plate-shaped main body 1 has an oblique side 2 at one corner, and a circular hole 3 near the oblique side 2. Inside the circular hole 3, a large diameter hole 4 is provided, which is concentric with the circular hole 3 and has a part of its circumference close to the oblique side 2, leaving the bottom part. A guide groove 5 extending in two directions of the diagonal piece is provided.

A rotating member 6 that is rotatably supported by a bearing provided at the bottom of the main body 1 and rotatably inserted into the circular hole 3 has a long groove-shaped recess 7 that is semicircular on the inside and open on the outside in the radial direction. 4 are provided at equal intervals, and opposing engaging pieces 8, 8 are provided below the recess 7.

The slider 10 has ballpoint pens 9 with different color inks at the tip. The slider 10 has grooves 11 on the top surface.
The ink is colored the same color as the ink on the rotary member 6, and engagement grooves 12, 1 are provided on both sides of the rotary member 6 so as to be engageable with the engagement pieces 8, 8 of the rotary member 6.
The moving member 10 is provided with an engagement groove 1
When the engaging pieces 2 are engaged with each other and moved toward the center so that the rear ends come into collision with each other, the tip surface is formed so as to be substantially flush with the outer peripheral surface of the rotating member 6, and is also formed so as to be insertable into the guide groove 5 having the same engaging piece 13 as the engaging piece 8 of the rotating member 6.

The oblique side 2 of the main body 1 is provided with a hole 14 that is parallel to the axis of the guide groove 5 and opens outward from the large diameter hole 4. When the rotating member 6 is inserted into the circular hole 3, the ballpoint pen 9 is positioned within the inner periphery of the large diameter hole 4, and when the slider 10 is inserted into the guide groove 5, the tip of the ballpoint pen 9 is It is formed to protrude from the hole 14 to the outside.

To write with this multicolor ballpoint pen, rotate the rotary member 6 from the stored state shown in FIG. 4, insert the slider 10 of the desired color into the guide groove 5, and insert the ballpoint pen 9 of the slider 14 (FIG. 1), and write while holding the mover 10 with your fingers.

When writing is finished, move the slider 10 from the guide groove 5 into the recess 7 of the rotating member 6, and rotate it to a point where none of the four sliders 10 can be inserted into the guide groove 5, as shown in FIG. Effects of the invention to create a storage state The present invention allows multi-colored ballpoint pens to be stored on a single flat plate, so it can be carried as a single card in an inner pocket or card slot.

In addition, the ballpoint pen can be moved in and out by rotating the rotary member and moving the slider of the desired color.Furthermore, since the structure is simple and the number of parts is small, it is highly practical as a low-cost simple writing instrument.
