Abstract

Provided is a pen shaft that reduces the catch of a pen tip on paper and realizes a smooth writing feeling. A pen shaft according to the present invention is provided with elasticity to a core 5 to which a pen tip 7 is attached, and is not completely fixed inside a hollow shaft portion 2, and a base portion having a tip tube portion 1 and a buffer material 4. By gently supporting two points at 3, the pen tip movement and writing pressure can be absorbed to achieve a soft and smooth writing taste. [Selection] Figure 1

Description

The present invention relates to a pen shaft to which a pen tip is attached.

In the conventional pen shaft, the attachment portion of the pen tip is integrated and fixed with the pen shaft.

The pen tip, which is a hard material and fixed to the pen shaft, could be distorted and ink splashed when it was moved left and right or diagonally by scratching the paper.

The core to which the pen tip is attached is not completely fixed, but it has elasticity inside the pen shaft to absorb the pen tip movement and writing pressure.

Reduces the tip of the pen and achieves a smooth writing experience.

The pen shaft is composed of a tip cylinder part into which the pen tip is inserted, a hollow shaft part having a cushioning material such as silicon at the base part, and a shaft object having a length that reaches the base part of the shaft from the attachment part of the pen tip. It is a thing. The core is made of an appropriate material such as polypropylene, has elasticity, and has a stopper that is not pulled out when the pen tip is removed.

Hereinafter, an embodiment will be described with reference to the accompanying drawings. The nib on which the nib is attached is supported at two points, the front and the base, but by not fixing these two points completely, it creates a shock absorbing effect that absorbs the nib movement and writing pressure. .

The hole of the tip tube and the thickness of the lead are sized so that the pen tip can be inserted and removed smoothly. Keeping this area not too tight and not too loose creates ease of handling as a tool, as well as flexibility in the front support.

The brush stroke varies depending on the length from the tip tube to the base where the core reaches. If it is short, it will be hard, and if it is long, it will be soft. Differences in hardness and softness can be caused by differences in the elasticity of the core.
