JPS6023178Y2 - Nib for marking pen - Google Patents

Description

[Detailed description of the invention] The present invention relates to an improvement of a pen nib for a marking pen, in which the side ridgeline portion of the front part of the prismatic nib body is formed obliquely over the entire length. The gist of this is that the entire front section is narrow.

In the embodiment shown in FIGS. 1 and 2, the ridgeline portions 3, 3' on both vertical sides of the front surface 2 of the felt pen nib body 1, which has a flat prismatic shape, are obliquely formed over the entire length. The width of the entire front part 2 is made narrow by cutting it out, and the third part is
The embodiment shown in the figure is constructed by obliquely cutting out the vertical-to-blade side ridgeline portion 3 of the front portion 2 of the nib body.

That is, in the two embodiments described above, when drawing a thin line, the ridgeline indicated by a in the figure is used, and when drawing a thick line, the ridgeline indicated by an opening in the figure is used. be.

Conventionally, this type of marking pen nib has either a flat prismatic shape (see Figure 4) or a flat prismatic shape with the lower ridges of both the front and back sides cut out obliquely (
(see Figure 5), but in these, the ridge line indicated by A' in the figure is a thin line, and the ridge line indicated by an opening is a thick line. In any case, when drawing a thin line, the drawing condition was very unstable, so it was not always convenient to use.

The present invention aims to eliminate such defects, and as described above, the side ridgeline of the front part of the prismatic nib body is formed obliquely over the entire length, so that the front side Since all of the sections have a narrow width, when drawing a thin line, we can use the ridgeline shown in the figure, and when drawing a thick line, we can arbitrarily use the ridgeline shown in the figure, making it extremely stable whether it is a thick line or a thin line. It has the advantage of being able to be drawn in the same state, and in the present invention, the pen nib shown in Fig. 4 or a similar pen nib is used.
Unlike the tip of the nib described in No. 78476, in which only the tip of the nib is cut obliquely, when the tip writing part of the nib becomes deformed due to long-term or excessive use, it is possible to cut any part of the nib perpendicular to its longitudinal direction. By cutting the pen nib, it is possible to very easily reproduce two well-ordered wide and narrow ridge lines at the tip of the pen nib, which is extremely convenient.
