Description

  The present invention relates to a swinging wooden sword that can be used indoors.

Conventionally, a general wooden sword has an oval shape with a flat cross section, and there are many red cocoons and white birch, and there are also expensive materials such as ebony, sandalwood, sunsuke, and cocoon.
There are large swords and small swords according to the length of the sword and small sword. A large sword is about 1 m, and a small sword is about 50 cm to 60 cm. Some Japanese swords have a sword when they practice Japanese Kendo and practice strongly.
There are some swinging wooden swords for training that aim to train the inside of the hand by increasing the length to 1.15 m and making the blade extremely thick and heavy, such as octagons and bowls.
Also, even a general wooden sword for swinging is provided with a thick blade and a length exceeding 1 m, and about 1.15 m.

Patent Documents 1 and 2 show drawings, and Non-Patent Document 3 presents a swinging wooden sword shown in FIG. 9 as being sold.
The swinging wooden sword shown in FIG. 9 has a length slightly exceeding 1 m, has a flat shape, and the blade 10 has substantially the same thickness and warps like a Japanese sword from the tip of the sword to the handle. A ridge 11 extending from the vicinity of the tip to the vicinity of the handle is recessed.

The basic way to grip bamboo swords in Kendo is to squeeze a rag. In order for beginners to learn the shape, you can learn how to sharpen with a wooden sword and then grip the bamboo sword.
If you hold a bamboo sword from the beginning and practice it, it will tend to become a grip of a baseball bat, and you will not be able to hit it correctly.
Although it is better to use a general-style wooden sword for both swing and kendo, the weight was not enough to swing with a general-type wooden sword. The general swinging wooden sword is thick and naturally thick, so the swinging was not alive in the game and the grading examination.

The wooden swing swords that have been sold in the past have a length of more than 1 meter, so there was a demand for swinging for training inside the house, but if you swing around in a general house or apartment, it hits the ceiling. It did not come true.
Therefore, under the guidance of the high-ranking people, they had to practice in-hand training, such as how to use the fingers, wrists, and arm muscles, in a kendo field and a wide outdoor area.

In addition, a 115 cm swinging wooden sword would be about 1 kg and 106 cm would be 800 g heavy. In addition, the length of the handle was good but it was too thick, so there was a sense of incongruity when switching to a bamboo sword, and the practice of swinging could not live. Similarly, in the Kendo form using a general-type wooden sword in the grading examination, the practice of swinging was not utilized.
The practice of swinging in kendo is to swing bamboo swords and wooden swords up and down, diagonally up and down, vigorously, swing vigorously and straightly and stop suddenly.

Article 12 of the All Japan Kendo Federation's Kendo Match Judgment Rules states, “Effective hits have a vigorous and appropriate attitude, and the hitting part of the hitting point of the bamboo sword hits correctly and is remnant. Article 13 states that “the sword hitting portion of the bamboo sword is the blade portion (opposite side of the string) centering on the object hitting”.
And in the Kendo Match Referee Rules Rules Article 10, the meaning of the phrase “Blade Straight” in Article 12 of the Rules is defined as the case where the direction of the sword's impact and the direction of the blade portion are the same direction. ing.

Therefore, the conventional swinging wooden sword shown in FIG. 9 generates a sound that cuts the air even if it is not correctly shaken, so it will be misunderstood as a correct swing, so it is used as training for passing the escalation examination. It can be said that it is not appropriate as a swing blade.
In addition, wooden swords are used as a part of the practical skill of the grading examination, but the examination will not pass if you cannot realize that you will be able to swing correctly in the practice of daily practice.

  In the old days, it was effective to use heavy wooden swords to increase their weight, but in recent sports kendo, it is important to swing faster and hit one step ahead of the opponent. Therefore, it can be said that even adults need light swinging wooden swords of around 700g, high school students of around 650g, and junior high school students of around 600g so that heavy wooden swords can be avoided. However, because it has not been commercialized, a thick swinging wooden sword including the handle is used.

The present invention has been made to solve such problems, practice swing for wooden sword according to claim 1, the length of the entire the 75cm to 95cm, blade is successively thicker towards the point of a sword with no warp straight sword If the blades are recessed on both sides of the blade and the blades are shaken correctly, a wind noise will be generated. The handle will be 9 to 10.5 cm at the head of the handle and 10 to 12 cm at the border of the blade. It is characterized in that it has a thick cross-sectional ellipse shape and the overall weight is 550 to 750 g.

The wooden sword for swinging according to claim 2 is characterized in that the heel has a width of 6 mm, a depth of 3 mm to 5 mm, and a length of 15 cm.
The swinging wooden sword of claim 3 is characterized in that the heel has a width of 6 mm, a depth of 3 mm to 5 mm, and a length of 50 cm.

The present invention is configured as described above. In the first aspect of the present invention, since the total length is set to about 75 cm to 95 cm, if the height is normal, the practice can be practiced indoors. In addition, since the handle gripped at that time is almost the same thickness as a bamboo sword or a general wooden sword, there is no sense of incongruity when you swing the bamboo sword in a game or ascending test, and the practice of swinging will live. In addition, because it was a straight sword without warping the blade was sequentially thicker toward the point of a sword made in the same manner as in the warp of the Japanese sword, the sound cut the air is to be generated by the gutter when you shook blade muscle correctly. Make sure that the bag is of appropriate length depending on the level of proficiency. In addition, with a straight sword like a bamboo sword, if the width of the body was the same from the handle to the tip of the sword, almost no wind noise was generated even with a spear.

In the invention of claim 2 , since the heel has a width of 6 mm from the sword tip side, a depth of 3 mm to 5 mm, and a length of 15 cm, it can be said to be suitable for a high-level person. This is because if the length of the ridge is short, the wind noise will not occur unless the blade is shaken correctly.
In the invention of claim 3 , since the length of the heel is 50 cm and is provided on almost all blades, wind noise can be generated relatively easily if the blade is correct.
As the rank rises, you must pass a large kendo, so you will not pass the examination. If you do the right thing, a wind noise will be generated, which is suitable for practicing the swordsmen participating in the grading process, and the wind noise will encourage and improve it.

The present invention will be described below with reference to the embodiments shown in the drawings.
FIG. 1 is a front view of a swinging wooden sword S according to the present invention, FIG. 2 is a perspective view of the main part, FIGS. 3 to 6 are enlarged sectional views of FIG. 1, and FIG. 7 is a swing of another embodiment. It is a front view of a wooden sword.
This swinging wooden sword S shown in FIG. 1 to FIG. 6 is constructed by cutting out the material as white birch.
The total length is 85cm, which is shorter than before, so that it cannot be used on the ceiling even if it is swung down from the top in the room. This can be used by people up to about 180 cm tall.
The handle 3 is gradually thickened from the head 1 to the sword tip 2, the blade 3 is 53cm, and is gradually rounded toward the sword tip 2. That is, the handle 4 is 10cm from the blade 3 to the blade 3 In order to be 11 cm at the boundary, the cross section is gradually formed into an elliptical cross section.
The blade 3 is provided with a scraping part 6 inclined toward the blade part 5 so as to form a pointed end.

As a mark for separating the handle 4 and the blade 3, a circumferential groove 7 having a width of 3 mm and a depth of about 1 mm is provided at a position from the handle head 1 to 32 cm. Adults may change the position of the handle 4 to suit their own. Therefore, a long 32 cm position as the handle 4 is attached as a guide. Therefore, instead of the circumferential groove 7, a low protrusion may be used, or a light color may be separately applied as a mark.
The position of the circumferential groove 7 may be provided at the longest position of the handle 1 to 34 cm.
The thickness of the handle 1 is 10 cm to 10.5 cm, and is about 11 cm per circumferential groove 7 as a mark. The thickest part near the sword tip 2 is 13 cm to 15 cm.
Although not shown, when the adult bamboo sword is covered with a handle, the thickness of the handle becomes 9.5 cm to 10 cm. Even with a general wood sword, the thickness of the handle is about 10 cm. And the thickness of the handle at the place where the bamboo sword holds with the right hand is 11 cm. The thickness of the handle 4 in the embodiment conforms to these. Therefore, when the bamboo sword is shaken in the ascending test, the practice of the swinging wooden sword can be utilized.
However, in the past, the cross-sectional shape of the handle part gripped with both hands is limited to a round shape or an oval shape, and the blade 3 has a round shape, that is, a real shape of the cross section. The cross section is elliptical to match the wooden sword.

An arcuate scissors 8 are formed in the curved surface so as to squeeze toward the blades 5 on both sides of the blade 3, and the air is cut off when the blades are shaken correctly.
The rod 8 has a width of 6 mm, a depth of 3 mm to 5 mm, and is provided from the sword tip 2 side. The length is 15 cm. As the length is shorter, the wind noise is not generated unless the blades are shaken correctly and greatly.

FIG. 7 shows another embodiment, in which the length of the ridge 8 is increased to 50 cm. This is suitable for beginners, and it is relatively easy to generate a wind noise. However, if the blade does not swing correctly, no sound is generated, so that it is suitable for practice alone.
Although not shown in the drawing, for examinees with up to six stages, a bag 8 having a length of 30 cm to 40 cm may be provided. The width of the ridge 8 is not limited to 6 mm, and can be narrowed or widened appropriately.

The total length of the swinging wooden sword S is 85 cm, and white cocoon is about 650 to 750 g. However, red cocoon is about 550 to 650 g.
Even for adults, up to around 700g, high school students around 650g, and junior high school students around 600g will fall within the proper range of light swinging wooden swords.
The entire length of the swinging wooden sword S can be within a range of 75 cm to 95 cm, and by selecting a material and a length according to the height of the user, the length can be kept within a predetermined weight range and used in a room. .
In addition, it can be said that it is appropriate for the handle 4 for middle and high school students to have a thickness of 9 cm at the handle head 4 and 10 cm at the border with the blade 3.

Speedy swinging is important, but the faster you swing, the more you are not a high-ranker, and the posture will collapse and you will not be able to swing through the blade. In the swinging wooden sword according to the present invention, although the length of the spear 8 is short and long, the sound will not be generated unless it is swung correctly.
One of the most important things in practice is “cutting back”. This is a practice in which a person stands in front and hits the left and right sides alternately. The left side can be hit easily from a normal stance, but the right side can not be hit unless the wrist is returned largely, so it becomes unnatural and it is difficult for beginners and high-rankers to swing down and hit it correctly. .
If wind noise is generated on both the left and right sides after turning back, it can be said that you have learned how to grip correctly and strike the blade.

  In the embodiments described so far, the cross-sectional shape of the blade 3 is a round shape, that is, a solid shape. However, the cross-sectional shape of the blade 3 is not an ellipse, and the side surface is thinned toward the blade portion 5. As shown in FIG. 8, even if it is a flat kite (b), a sword kite (b), or a kite kite (c), a wind noise will be generated if the kites 8 are provided on both sides. Therefore, it is good also as these forms. However, since the large volume is a round bowl, that is, a solid form, it can be said that a round bowl is suitable for securing a predetermined weight with a white bowl or a red bowl when the total length is short. The shape of the blade 3 in FIG. 8 can be selected by using a material that is a little longer, such as a white rabbit or a red rabbit, or a material with a high specific gravity.
