Description

  The present invention relates to a writing pen, particularly a hard pen nib.

  The fountain pens, ballpoint pens, and pencils that people currently use have come from the western countries from the end of the 19th century to the beginning of the 20th century, and have been replaced by brushes because of their portability, ease of use, and speed of writing. It became the main writing instrument. The writing surface of the pen tip of this type of pen is usually a spherical surface, and the written handwriting is a locus of points, that is, a combination of simple lines, which is relatively suitable for writing phonetic characters. However, it is difficult to express kanji suitable for writing with a brush. This is because the writing brush tip has a soft conical shape and has a natural writing brush. When writing, the writing surface becomes a drop-shaped surface that changes variously depending on the top and bottom of the writing tip (rise) and the rotation of the writing brush. This is because handwriting is a combination of varied lines. In addition, characters written with a brush have an element of "draw" at the same time as "write", so it is certainly not easy to write kanji neatly with a general hard brush.

  There are mainly two types of improvements to the pen nib in recent years. One is to fold the front of the fountain pen nib at a certain angle, and the other is to keep the front of the fountain pen nib up. It is to make an arc degree curve. Both of these methods change the size of the contact surface between the nib and the paper by controlling the angle at which the nib contacts the paper when writing, and the thickness of the handwriting written thereby changes in thickness. It is something that attaches. Further, as the contact surface between the nib and the paper increases, the writing surface changes from a round point to an isosceles triangle, and the apex angle of the isosceles triangle forms a writing brush. There are three deficiencies in these two types of pen nibs. First, since the apex angle of the writing surface of the isosceles triangle is usually about 20 °, the two base angles cannot effectively form the brush, and only the brush formed with the apex angle can be used. There are many drawbacks of “side brush” (writing brush is biased when writing), and brush writing is based on the basic rule that the main rule is “medium brush” (when writing, bring the brush into the middle of the stroke) It is a point that does not fit. Secondly, the writing surface of the isosceles triangle does not have the arc of the waterdrop-shaped writing surface of the brush, and it feels firm when writing curved lines such as points, bends / bounces, left-handed, right-handed. Is a point. Third, when writing, the contact angle between the nib and paper must be constantly changed and the nib must be rotated, which makes it difficult for ordinary writers to master and affects the writing speed. is there.

  The present invention provides a writing pen tip suitable for writing Chinese, Japanese, and Korean characters, with the writing surface imitating the writing surface of a brush writing tip.

  The technical scheme adopted in the present invention is that the writing surface of the tip of a general hard brush (except for ballpoint pens) is designed in a fan-shaped plane, and the fan-shaped circle center angle is 37 ° (see Fig. 1). The depression angle between the bisector 1 of the heart angle and the axis 3 of the nib 2 is 50 ° ± 5 ° (see FIG. 2). When the fan-shaped plane is rotated 90 ° clockwise with the midpoint 4 (see FIG. 2) of the bisector of the center angle of the circle as the center, the pen tip becomes adapted to the left hand writing.

  The technical scheme adopted in the present invention has the following features. Firstly, the fan-shaped writing surface of the present invention has three tips of a fan-shaped circle center angle 5 and two depression angles 6 and 7 (see FIG. 1) due to the fan-shaped radius and arc. When writing, it naturally forms a brush 8 (see Fig. 3), and the two depression angles due to the fan-shaped radius and arc are also at a reasonable angle of 37 °, so there are two effective points when writing. The brush strokes 9 and 10 (see FIG. 3) are formed, and the brush stroke can be generated in each direction and the “medium stroke brush” can be realized without greatly rotating the pen tip. Among them, the tip 5 is responsible for writing and, if necessary, the “side scribble brush”, the tip 6 is responsible for the lower and lower left “medium stroke brush”, and the tip 7 is the “right and lower right” “medium stroke brush”. (See Figure 3). The principle is that the bisector 12 of the corner of the fan-shaped projection 11 of the forearm and the nib writing surface is positioned on the same straight line when the writer uses the present invention, and the writer's body 45 Assuming that the “horizontal” image and the “vertical” image are of equal width, and the center angle of the sector projection is set to ∠8, the “vertical” image in FIG. The angle between the radius of the fan-shaped projection in the center and the left side line of the “vertical” image, and the angle between the radius of the fan-shaped projection in the “horizontal” image and the upper side line of the “horizontal” image (45 ° −1 / 2 × ∠8) Tan (45 ° −1 / 2 × ∠8) = ½, that is, when brush brushes 9 and 10 in FIG. 3 are in the middle of strokes 14 and 15, respectively, fan-shaped projection center angle ∠8 is It is equal to 36.8 °, and the circular center angle of the fan-shaped writing surface of the present invention is 36.8 °, which is about 37 °. Second, the depression angle between the axis 3 of the nib 2 of the present invention and the fan-shaped writing surface is 50 ° ± 5 °. When writing with a brush, that is, when the brush axis (pen axis, brush tube) is held in a recess between the thumb and forefinger, the pen axis and the writing surface form a natural angle. This is also called the grip angle, because this angle is usually about 50 °. Therefore, when the nib axis of the present invention and the axis of the brush axis are parallel or overlapped, the axis 3 of the nib 2, the writing surface and the fan shape The depression angle with respect to the writing surface is about 50 °, specifically 50 ° ± 5 °. When the depression angle between the axis 3 of the nib 2 and the bisector 1 of the circular center angle of the fan-shaped writing surface is 50 ° ± 5 °, that is, the projection of the axis 3 of the nib 2 on the fan-shaped writing surface and the fan-shaped writing surface The bisectors of the center angle overlap and the center angle of the fan-shaped writing surface is located at the top of the nib 2 (see Fig. 2). It starts from the upper left of the character, and the characters in the middle, Japanese, and Korean are generally written from the upper left and written from the left to the right (see FIG. 3). If the fan-shaped writing surface is further rotated 90 ° clockwise with the midpoint 4 of the bisector 1 of the center angle of the circle as the center of the circle, the pen tip will circle the top of the nib 2 from the right hand when writing. This is equivalent to rotating 90 ° clockwise as a heart to the left hand (viewed from above) and simultaneously rotating the writing surface 90 ° counterclockwise (viewed from above). The same effect as writing with the right hand is obtained, that is, it is suitable for writing with the left hand. Fourthly, the arc of the fan-shaped writing surface according to the present invention is useful for forming a stroke curve such as a point, a turn / bounce, a left-handed payment, and a right-handed writing when writing. Fifth, when the present invention is used, most writing techniques of a brush can be adopted to exhibit the natural writing effect of a brush. Sixth, since the present invention does not change the coloring method when writing a general hard brush, the tip of a fountain pen, the tip of a felt pen, the tip of a micro-hole plastic brush pen, the tip of a mechanical pencil, the chalk It can be applied to the pen tip of various brush strokes excluding the ballpoint pen. Seventh, when the present invention is used, it is not necessary to change the contact angle between the pen tip and the paper significantly, and the writing speed is not affected.

  The present invention is suitable for daily writing of Chinese, Japanese, and Korean characters, and is also suitable for creating calligraphy.

  When using the present invention, the writer should place the bisector 12 of the corner of the fan-shaped projection 11 of the forearm and the writing surface of the nib on the same straight line and make an angle of 45 ° with the writer's body. (See Fig. 3) is recommended. If written at this angle, the functions of this utility model can be most easily realized. In addition, when writing at this angle, when the pen tip is moved with the finger of the hand, the resistance from the wrist is minimized, and the writing speed is the fastest. If the writer is already accustomed to other angles, when using the device, turn the wrist, keep the nib at a certain angle with the forearm, and use the angle of the fan projection on the writing surface of the device. All you need to do is divide the body and body at a 45 ° angle.

  As shown in FIG. 3, when the bisector of the angle of the fan-shaped projection formed by the writing surface of the present invention forms an angle of 45 ° with the writer's body 13, There is no need to rotate the pen tip when writing the “horizontal” image 15, and the brush blades 9 and 10 can be positioned in the middle of the stroke by simply moving the pen tip downward and to the right. For other handwriting, the above-described effects can be obtained by slightly rotating the pen tip.

It is a front view of the writing surface of this invention. It is a side view of this invention. It is the schematic of fan-shaped projection on the writing surface of the writing surface when using this invention, and its "medium pen writing".
