Description

  The present invention relates to a brush used for calligraphy.

  In order to write letters beautifully with a brush, it is very important to use delicate brushes such as hiragana “no” and “ha”, etc. It becomes.

  When writing a bent part of a character, the tip of the brush must be rotated, and it was difficult for children and beginners to understand how to carry the brush. Therefore, especially when a child reaches the bent part of a character, the movement of his / her hand is temporarily stopped each time, with one hand attached at that position, the writing brush is rotated and the head is turned in the direction of bending, or the tip is forcibly pushed. It was easy to write while bending. When writing the part where the character bends in this way, the tip was disturbed when the writing was completed, and the tip had to be reshaped to write the next line. This makes it impossible to smoothly write the bent part of the character, and the character may have a different shade of ink, or the thickness of the line may change, resulting in a poor balance of the entire character and writing a beautiful character I could not. In addition, the tip had to be remade each time, which was troublesome.

In addition, when writing a stop, splash, or payout part of a character, delicate writing pressure is necessary to smoothly move the tip to the next writing line, and for beginners to control the writing pressure. It was also difficult to understand the delicate brush usage. For this reason, when stopping, repelling, and paying characters, the writing pressure becomes too large and the tip of the tip is bent into a shape of a tip, and when writing the next line, the tip must be realigned. I couldn't write flowing beautiful characters.
In this way, it is extremely difficult for anyone to learn how to brush and use a brush, so it is necessary to have a high level of skill to write beautiful characters.

  Therefore, an object of the present invention is to provide a writing brush that anyone can easily write beautiful characters regardless of age or experience from children to the elderly.

  In order to achieve the above object, the invention according to claim 1 of the present invention comprises a tip, a neck for fixing the tip, a trunk, and a rotating means for rotating the tip, and the rotating means. The neck portion and the trunk portion are connected by each other.

  Here, the rotating means is a concept including all means capable of integrally rotating the tip and the neck around the axis of the brush, and the neck and the trunk as in the invention of claim 2. It is desirable to make the bearings rotate with respect to each other.

  The invention according to claim 3 of the present invention is characterized in that the rotating means has anticorrosive properties.

  According to the first aspect of the present invention, since the tip rotates following the carrying of the brush, especially the hiragana bends, the stop of the characters, the repelling, the paying of the brush can be carried easily and smoothly. Because the brush can be manipulated as you wish, anyone can easily write beautiful characters. In addition, the brush strokes are smooth and the tip is hard to break, eliminating the need to arrange the tip in the middle and writing the characters so that they flow with a single brush, eliminating the difference in ink shade and making the thickness of the line uniform. In addition to that, it is possible to write beautiful characters that are balanced overall. Furthermore, since various typefaces can be easily written and a new typeface can be created, it is possible to provide a very novel writing brush that has never existed before.

  According to the second aspect of the present invention, since the neck portion and the body portion rotate with each other by the bearing, it is possible to reduce the friction generated in the bearing and to further smoothly rotate the neck portion and the tip.

  According to the invention of claim 3, since the corrosion of the rotating means can be prevented even if the brush is washed with water, it is possible to maintain the smooth rotation of the tip and the same as the conventional brushes. It becomes possible to handle.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the writing brush of the present invention includes a tip 1, a neck 2, a body 3, and a rotary bearing 4. A tip 1 is firmly fixed to one end of the neck 2, and a recess 5 is formed at the other end. The body 3 has a cylindrical shape, one end is open, and the cap 6 is fixed to the other end. The rotary bearing 4 is composed of a stainless steel rotary pin 7, cylindrical rotary members 8a and 8b made of plastic, and thin disks 9a and 9b also made of plastic. An insertion hole 10 for inserting the shaft portion 7a of the rotating pin 7 is formed at the center of each of the rotating members 8a, 8b and the disks 9a, 9b. Only the insertion hole 10 of the rotating member 8b is formed so as not to penetrate the rotating member 8b.
Here, the material of each member constituting the rotary bearing 4 is not limited to the above as long as the material does not corrode each part even if the brush is washed with water.

  The writing brush of this invention is completed by assembling each part comprised in this way as shown to Fig.3 (a) (b) (c). First, the rotary bearing 4 is assembled (FIG. 3A). The shaft portion 7a of the rotation pin 7 is inserted into each insertion hole 10 in the order of the disk 9a, the rotation member 8a, the disk 9b, and the rotation member 8b. Then, the assembly is completed by driving the tip portion of the shaft portion 7a further into the insertion hole 10 of the rotating member 8b and fixing it. By assembling in this way, the rotating members 8a and 8b can be divided into one that rotates integrally with the rotating pin 7 and one that rotates independently, so that the rotating members 8a and 8b can be rotated relative to each other. It becomes possible. Further, by arranging the rotating members 8a and 8b and the disks 9a and 9b alternately, the disks 9a and 9b are arranged between the head 7b of the rotating pin 7 and the rotating members 8a and 8b. Therefore, the disks 9a and 9b serve as washers, and the rotational resistance of the rotating members 8a and 8b can be reduced, so that the rotating members 8a and 8b can be rotated more smoothly. Here, the method for fixing the tip end portion of the rotating pin 7 to the rotating member 8b is not necessarily limited to driving the tip end portion of the rotating pin 7 into the rotating member 8b, and the insertion of the rotating member 8b using an adhesive is performed. The tip of the rotary pin 7 may be fixed in the hole 10. In this case, the insertion hole 10 of the rotating member 8b needs to be provided so as to penetrate the rotating member 8b, or be provided so that the tip end portion of the shaft portion 7a of the rotating pin 7 is completely accommodated. .

Next, the neck part 2 and the trunk | drum 3 are connected using the rotary bearing 4 mentioned above. First, as shown in FIG. 3B, the rotating member 8a on the head 7b side of the rotating pin 7 of the rotating bearing 4 is fitted into the recessed portion 5 of the neck portion 2, and fixed in the recessed portion 5 with an adhesive. Next, as shown in FIG. 3 (c), the rotating member 8b of the rotating bearing 4 protruding from the neck 2 is fitted into the barrel 3 and fixed to the inner peripheral wall of the barrel 3 with an adhesive. , 3 is completed. In this way, by fixing the neck 2 and the body 3 to the left and right rotating members 8a and 8b around the disk 9b of the rotary bearing 4, as shown in FIG. Since the disk 9b can be rotated between the parts 2 and 3, the rotation of the parts 2 and 3 becomes very smooth. Further, all members other than the disk 9b of the rotary bearing 4 are provided. Is housed in the neck portion 2 and the body portion 3, the rotary bearing 4 cannot be seen from the outside, and the appearance is the same as a conventional brush.
Here, the size of the disks 9a and 9b of the rotary bearing 4 is not particularly limited, but the disk 9b disposed between the rotating members 8a and 8b is exposed to the outside of the brush. Therefore, in order to improve the appearance of the writing brush and not to obstruct the holding of the writing brush, it is desirable to make it approximately the same diameter as the diameter of the body portion 3 or slightly smaller than that. The rotary bearing 4 fitted into the recess 5 of the neck 2 is not limited to the rotary member 8a on the head 7b side of the rotary pin 7, but is a rotary member 8b on the tip side of the shaft portion 7a of the rotary pin 7. There may be.

  FIG. 5 shows the rotation state of the tip. By writing a character with the body 3 in the same way as a conventional brush, you can use it to write a bent part, such as Hiragana "No", or a character's splashing or paying part. Accordingly, the neck 2 and the tip 1 rotate as a unit, and the tip 1 always faces in the direction of travel, making it possible to write characters smoothly, and anyone can learn easily without having to learn to use a brush. Can write beautiful characters.

  In the brush of the present invention, as the length of the tip 1 becomes longer, the distance between the portion having the brush (the body portion 3) and the tip of the tip 1 becomes larger, so that the rotational moment when writing characters becomes larger and the tip becomes larger. Becomes easier to rotate. Also, as shown in FIG. 6, by holding by hand so as to straddle the neck portion 2 and the trunk portion 3, it becomes possible to restrict the rotation of the tip 1 and use it like a conventional brush, which is very versatile. This is a brush that has never been better.
