Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a brush pen that can be used with the same feeling as a brush for calligraphy (hereinafter referred to as the main brush).

[0002]

[Prior art]

 With this brush, which has a tip formed by bundling bristles on the tip of a shaft made of bamboo, etc., the ink is written with ink and ink that is made of ink and ink. Since it is written in one stroke without being included in the tip of the brush, when the letters are large, the amount of ink in the tip of the tip is reduced during writing, and there is a difference in the shade between the beginning and end of a letter, and Can often be done. And this difference in shade and "kasure" are considered to be the unique taste of calligraphy.

However, in order to use this brush, it takes a lot of time to prepare the ink, and since it requires many tools such as a sash and a sash box, it is expensive and not suitable for carrying. . For this reason, a writing pen has been put into practical use, in which an ink cartridge is stored in the shaft cylinder or ink is directly filled in the shaft cylinder to supply ink to the tips attached to the tip of the shaft cylinder for writing. .

[0004]

[Problems to be solved by the device]

 By the way, since brush pens have the advantage of being easy to use, they are widely used for New Year's cards written at home.However, when the ink in the tip is consumed, the ink in the barrel is sequentially supplied to the tip. Since it can be written in a uniform density without causing a difference in light and shade or "shading", it becomes a flat character. In other words, the brush pen cannot be used in the same way as the main brush. For this reason, not only in full-fledged calligraphy, but in the time of calligraphy in elementary schools and in calligraphy classes for children, the brush is used exclusively despite the inconveniences mentioned above.

Therefore, the present invention can cause a difference in shading or “sharpness” when a character is large, and can be used with the same feeling as a writing brush in which India ink is included in the tip of the writing brush. It is an object of the present invention to provide a brush pen that can be used with the same feeling as a conventional brush pen by sequentially supplying the brush to the tips.

[0006]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention provides a writing pen in which ink in a barrel is supplied to a tip formed by bundling bristles to write on the tip, and the tip is attached to the tip. In addition to forming a small ink chamber that is equal to the amount of ink that can be contained in the valve, it also has a built-in valve mechanism consisting of the valve section of the valve tube connected to the shaft tube and the vertical groove formed on the inner peripheral surface of the large tube. On the other hand, when the shaft cylinder is rotated, the valve mechanism opens and closes, and when the valve mechanism opens, the ink in the cylinder is filled in the small ink chamber and the ink in the small ink chamber is supplied to the tips.

[0007]

[Action]

 That is, when the shaft cylinder is rotated with respect to the large tip, the valve mechanism is opened, the ink in the shaft cylinder is filled in the small ink chamber equal to the amount of ink that can be contained in the tip, and the shaft cylinder is rotated with respect to the large tip again. Since the valve portion of the valve cylinder closes the vertical groove formed on the inner peripheral surface of the large tip to close the valve mechanism, only the ink in the small ink chamber is supplied to the tip. In other words, the result is the same as adding ink to the tip of the brush, and the ink is not constantly supplied to the tip as the ink is consumed. Therefore, the difference in shading and “blurring” can be seen in the characters, and it can be used with the same feeling as with this brush. Further, if the writing is performed with the valve mechanism opened only by rotating the shaft cylinder once with respect to the large tip, the ink is sequentially supplied to the tips, so that the writing can be performed with the same feeling as a conventional writing pen.

【Example】

 The present invention will be described in detail below with reference to the embodiments shown in the drawings. As shown in FIG. 1, ink having a relatively high viscosity is directly filled inside the barrel 1, but a valve barrel 4 is connected to the tip of the barrel 1 via a joint 5. The tip 3 is the same as the tip used for a bold brush, and is fixed to the large tip 2. The large tip 2 is provided with a small air hole 22 that allows the exchange of air and ink during writing and prevents ink from leaking. The tip of the valve cylinder 4 is inserted into the large tip 2 and is rotatably connected to the large tip 2. An O-ring 6 is interposed so that ink does not leak from the connecting portion between the valve cylinder 4 and the large tip 2.

As shown in FIG. 2, the valve cylinder 4 is provided with a partition wall 41 inside the tip inserted into the large tip 2, and a cylinder part near the partition wall 41 is a valve part 44. A second window hole 43 and a first window hole 42 are provided before and after the partition wall 41. That is, the second window hole 43 and the first window hole 42 are provided so as to face each other in the tubular portion that constitutes the valve portion 44.

On the other hand, on the inner peripheral surface of the large tip 2, two vertical grooves 21 are provided so as to face each other. Then, the partition wall 41 of the valve cylinder 4 is located at the center of the vertical groove 21, and the valve cylinder 4 rotates 90 °, so that the valve portion 44 or the second window hole 43 and the first window hole 42 are formed. Face the flute 21. That is, the valve portion 44 and the vertical groove 21 constitute a valve mechanism. As shown in FIG. 4, when the valve portion 44 faces the vertical groove 21 and closes the vertical groove 21, the valve mechanism is closed, and as shown in FIG. As shown, when the valve portion 44 rotates 90 ° and the second window hole 43 and the first window hole 42 face the vertical groove 21, the valve mechanism opens. The space below the valve mechanism is the small ink chamber 9, and the capacity of the small ink chamber 9 is so small that the tips 3 can contain the ink in the small ink chamber 9 at one time.

When not in use, as shown in FIG. 2, the valve portion 44 faces the vertical groove 21 and closes the vertical groove 21 to close the valve mechanism, and the ink does not exist in the small ink chamber 9. Then, when writing, when the barrel 1 is rotated 90 ° with respect to the large tip 2, the second window hole 43 and the first window hole 42 face the vertical groove 21 as shown in FIG. The mechanism opens and ink enters the small ink chamber 9. Then, when the barrel 1 is again rotated 90 ° with respect to the large tip 2, the state shown in FIG. 2 is restored and the valve mechanism is closed.

The ink that has entered the small ink chamber 9 is supplied to the tip 3, but the amount of this ink is such that the tip 3 can contain it at once, and the valve mechanism is closed so that the inside of the barrel 1 is closed. Since the ink of No. 3 does not enter the small ink chamber 9, that is, the ink is not supplied to the tip 3 any more, the state is the same as that of adding ink to the brush. Therefore, when a large character is written in such a state, a difference in shading and a “blurring” occur, and it can be used with the same feeling as that of the main brush. Then, when the ink contained in the tips 3 is consumed, the above-described rotation operation may be performed again to continue writing.

When writing is performed in the state of FIG. 3 in which the second window hole 43 and the first window hole 42 face the vertical groove 21 and the valve mechanism is open, ink continuously enters the small ink chamber 9 and the tip of the ink is ejected. Since it is supplied to 3 sequentially, you can write with the same feeling as a conventional pen. Further, when writing is completed and the writing pen is carried, it is preferable to open the valve mechanism with the tip 3 facing upward, return the ink in the small ink chamber 9 into the barrel 1, and then close the valve mechanism. .

[0014]

[Effect of device]

 As described above, in the brush pen of the present invention, a small ink chamber equal to the amount of ink that can be contained in the tip is formed in the big tip to which the tip is attached, and the shaft cylinder is rotated with respect to the big tip. The valve mechanism opens and ink in the barrel is filled in the small ink chamber, and when the barrel is rotated again with respect to the large tip to close the valve mechanism, only the ink in the small ink chamber is supplied to the tips, It will be in the same state as when the ink was added to the brush, and there will be a difference in shading and “blurring” in the character, and you can use it with the same feeling as with this brush. In addition, when writing with the valve mechanism open, ink is sequentially supplied to the tips, so that you can write with the same feeling as a conventional writing pen.
