DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument holder which is convenient for holding two writing instruments which are simultaneously held and for writing using one of them.

[0002]

2. Description of the Related Art Knock-type ballpoint pens, in which two color cores alternately appear and disappear, and changing the color of the cores at both ends, are useful for writing quickly by selectively using two colors of ink or pencil. Also known are colored pencils.

[0003]

In the case of the above-mentioned ball-point pen, it is necessary to temporarily change the grip of the finger holding the pen to knock the operation piece, so that the color cannot be changed immediately. In addition, after the color change operation, the user again holds the pen and writes, so that the writing operation may be delayed.

[0004] In the case of a two-color pencil as well, it is necessary to change the top and bottom of the pencil upside down.

Accordingly, the present invention allows two writing instruments, such as a pencil and a ballpoint pen, to be held at the same time, so that the writing instrument can be replaced with the other writing instrument immediately without holding and re-grip. An object of the present invention is to provide a writing instrument holder that can operate.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a rectangular body formed of a metal plate on both sides by an extension of the metal plate on the same side of the body. Forming a semicircular writing tool holding part of a left-right symmetrical shape curved to form a radius of curvature of each holding part equal to or smaller than the radius of the writing tool held by the holding part, and between both curvature centers. Are formed to be equal to or shorter than the diameter of the writing instrument.

[0007]

When writing with the writing instrument holder having the above-described configuration, two writing instruments are held and integrated by each holding section.
In this state, the two writing instruments are simultaneously held in the hand, and the writing instrument holder is oriented vertically so that one writing instrument is on the top and the other writing instrument is on the bottom, and writing is performed with the writing instrument held by the lower holding section.

When the vertical relationship of the holding portion is changed by turning the holding portion halfway while holding the writing implement holder, one of the writing implements is placed below, so that writing can be performed. As a result, it is possible to immediately switch to one writing instrument without having to change the writing instrument being held. Also, it is possible to quickly move to the next writing operation.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIGS. 1 and 2 show a writing instrument holder according to an embodiment.

The writing instrument holder 1 is formed by bending a rectangular metal plate. A rectangular flat plate-shaped main body portion 2 is formed at the center portion, and the metal plate is provided on both sides of the main body portion 2. The writing tool holding parts 3, which are curved in a semicircular shape on the same surface side of the main body part 2 by the extension part, are formed.

Both ends of each holding portion 3, 3 are formed so as to reach lines L, L (see FIG. 2) connecting both ends of the main body portion 2 and the center of curvature O of each holding portion 3, 3 (ie, half). (It may be formed in a circular shape), but may be formed to slightly exceed the lines L, L as shown in FIG. 2 in order to increase the stability of holding.

The radius of curvature R of each of the holding portions 3, 3 is formed to be equal to the radius r of the writing implements 4, 4, but as shown in FIG. 2, the radius of curvature R is made slightly smaller than the radius r. Alternatively, the holding of the writing implements 4, 4 may be stabilized by the elasticity of the holding portions 3, 3 in the diameter reducing direction.

Further, the center of curvature O of each of the holding portions 3 and 3,
The interval D between O is twice as large as the radius r of the writing tools 4, 4, that is, equal to the diameter of the writing tools 4, 4. Also in this case, the spacing D may be slightly shorter than the diameter, and the writing implements 4 may be fastened to each other by the two holding portions 3 to stabilize the holding.

The height H (see FIG. 1) of the writing implement holder 1 is formed to be about three times the radius of curvature R of the holding parts 3 and 3, so that the writing implements 4 and 4 can be displaced in the longitudinal direction. Preventing.

The writing instrument holder of the embodiment has the above-described structure, and a method of using the same will now be described.

FIGS. 3 and 4 (a) show two writing tools 4, 4 'held by the writing tool holder 1, one holding portion 3 being on the lower side (the crotch side of the thumb and index finger) and the other. This is a state in which the holding unit 3 is vertically gripped on the upper side (fingertip side) and writing is performed by the writing implement 4 held by the lower holding unit 3. At this time, the other writing implement 4 'is away from the paper surface and does not contribute to the writing action.

Here, when changing to the other writing implement 4 ', the writing implement holder 1 is rotated by 90 degrees in the state as it is (see FIG. 4B), and further rotated by 90 degrees (FIG. 4B).
(C)). As a result, the holding units 3 and 3 are turned upside down and the other writing implement 4 'is on the lower side, so that writing can be performed with the writing implement 4'.

Further, when the film is reversed in the reverse direction or further rotated by 180 degrees in the circumferential direction, it returns to the original state (FIG. 4A).

[0020]

As described above, the writing implement holder of the present invention can hold two writing implements, so that the two writing implements can be simultaneously gripped and the vertical positional relationship can be turned half way as required. Thus, there is the convenience that the two writing instruments can be used immediately without almost interrupting the writing operation.

Further, since the two writing tools are held in parallel and in close contact with each other, the writing tool has the least bulk. Moreover,
Since the writing is performed in the lower row in a state where the writing is performed in the upper and lower rows, the writing can be performed without feeling uncomfortable to the left.
