Abstract

PROBLEM TO BE SOLVED: To make it possible to reduce the fatigue at a fingertip in writing with a writing utensil with a rigid penpoint and to express a personality by affluent characters. SOLUTION: A portion, the flexibility of which is given higher than those of the remaining holder portions, is provided between the portion, which is gripped with fingertips, of a holder and a portion, with which the penpoint is held, so as to deform in order to deflect the portion, to which the higher flexibility is given, when pressure is applied to the penpoint under the state that the holder is gripped with the fingertips.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument holder.

[0002]

2. Description of the Related Art In a conventional writing instrument holder having a hard pen tip, as a means for reducing fatigue of a fingertip at the time of writing, a shape devising for facilitating grasping a portion to be gripped with the fingertip of the holder is proposed. In order to prevent slippage with the fingertip, a device such as rubber or plastic having a soft and high friction coefficient is coated on the outer periphery of the holder.

[0003]

Most conventional writing implement holders having a hard pen tip are designed to make it easier to grasp the part to be gripped with the fingertip, thereby reducing the fatigue of the fingertip during writing. But the effect was small.

[0004] The present invention has been made in view of the above points, and an object of the present invention is to more effectively reduce the fatigue of a fingertip at the time of writing with a writing implement having a hard pen tip, and to provide richer characters. It is an object of the present invention to provide a writing instrument that enables the expression of individuality.

[0005]

SUMMARY OF THE INVENTION The present invention provides a writing instrument holder having a hard pen tip, which has a higher flexibility between a portion gripped by a fingertip and a portion holding the pen tip as compared with other holder portions. When the pressure is applied to the writing surface through the pen point while holding the holder portion with a fingertip, the portion having high flexibility is deformed and bent.

[0006]

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

FIG. 1 shows a conventional embodiment in which a pen shaft 9 is formed.
In a writing instrument provided with a holder 1 containing a pen and a nib holding part 4 holding a nib 3, a portion 2 to be gripped with a fingertip is separately coated on the outer periphery of the holder 1, and the shape and material are changed so that it is easy to grip with a fingertip. In addition, this is an example in which the fingertip is hardly slipped.

FIG. 2 shows a first embodiment of the present invention. In a writing instrument provided with a cylindrical holder 1 containing a pen shaft 9 and a pen tip holder 4 for holding a pen tip 3, the holder 1 is gripped. A recessed groove 5a is provided between the portion 2 and the pen tip holding portion 4;
The U-shaped groove wall 6a in this portion is made flexible, and when pressure is applied from the fingertip to the pen tip 3 through the grip portion 2 via the pen tip holding portion 4, the U-shaped groove wall 6a is deformed and the grip portion 2 is deformed. This is an embodiment in which bending occurs between the pen tip holding portion 4 and the pen tip holding portion 4.

FIG. 3 is a view showing a state in which the grip portion 2 of the holder 1 of the writing instrument in the embodiment of FIG.
FIG. 4 shows the state of FIG. 3 in which the pressure is applied to the pen tip 3 and the writing surface 7 from the fingertip through the grip part 2 through the pen tip holding part 4 to provide a depression 5a. U
This shows a state in which the mold groove wall 6a has been deformed and bent between the grip portion 2 and the pen tip holding portion 4.

FIG. 5 is different from the first embodiment of the present invention shown in FIG. 2 in that the amount of deformation and bending between the grip portion 2 and the pen tip holding portion 4 is regulated. This is an embodiment in which a color stopper 8 is provided, and the amount of deformation and bending is restricted within the range of a gap 5b between the inner wall of the color stopper 8 and the outer periphery of the holder tip 2a.

FIG. 6 shows a second embodiment of the present invention. In a writing instrument provided with a cylindrical holder 1 containing a pen shaft 9 and a pen tip holder 4 for holding a pen tip 3, the holder 1 is gripped. A notch 5 is provided between the portion 2 and the pen tip holding portion 4, and the portion left by the notch 5 is made flexible as an elastic wall 6.
When pressure is applied to the pen tip 3 via the pen, the elastic wall 6 is deformed and flexed between the grip part 2 and the pen tip holding part 4, and the amount of flexure is proportional to the pressure applied to the pen tip 3, This is an embodiment in which a stopper for restricting the amount of bending to a predetermined amount is a stopper A8a and a stopper B8b.

FIG. 7 is a view showing a state in which the grip portion 2 of the holder 1 of the writing instrument in the embodiment of FIG.
FIG. 8 shows a state in which the elastic wall 6 is deformed from the state shown in FIG. 7 by applying pressure to the pen tip 3 and the writing surface 7 from the fingertip through the grip part 2 via the pen tip holding part 4 to deform the elastic wall 6. 5 shows a state in which bending occurs between the pen tip holding unit 4 and the pen tip holding unit 4.

FIG. 9 shows a third embodiment of the present invention, in which a writing instrument having a cylindrical holder 1 containing a pen shaft 9 and a pen tip holding portion 4 holding a pen tip 3 is used to grip the holder 1. An intermediate joint 10 in which rubber 6b, which is a kind of highly flexible material, is vulcanized and bonded in the middle between the part 2 and the pen tip holding part 4, and the grip part 2 is passed from the fingertip through the pen tip holding part 4 In this embodiment, when pressure is applied to the pen tip 3, the rubber 6b is deformed to bend between the grip part 2 and the pen tip holding part 4.

[0014]

As described above, according to the present invention, a portion having higher flexibility than the other holder portions is provided between the portion of the holder gripped by the fingertip and the portion holding the pen tip. From the writing surface through the pen tip,
From the writing surface when excessive pressure is applied to the writing surface from the fingertip through the pen tip during writing, or the fine shocking reaction force to the fingertip due to the unevenness of the writing surface when running the pen tip on the writing surface The reaction force to the fingertips can reduce the fatigue of the fingertips because the part that has high flexibility between the part gripped with the fingertip of the holder and the part holding the penpoint can be deformed and flexed, reducing the fingertip fatigue can do.

Further, the portion between the portion held by the fingertip of the holder and the portion holding the pen tip bends, so that it is possible to carry a brush similar to a brush and to express personality with richer characters. .
