Description
本発明は、剣道の修行をする者が使用する素振り用木刀に関する。 The present invention relates to a swinging wooden sword used by those who practice kendo.
従来の木刀は、主に二つの目的を持った物が作られている。 Traditional wooden swords are mainly made for two purposes.
一つは、真剣を模造し柄の部分の断面は瓜実形をなし、刀身部分も若干刃部は薄くなっているがほぼ瓜実形の断面をしている。そして剣先に行くほど細く軽くなっている。刀身の反りも全長の1％程でほぼ直線に近い。主に剣道形の練習に使用されている。長さは１０２ｃｍ。全体の重量は、５００g程度である。（図１参照） The first is to imitate a serious sword, and the cross section of the handle has a real shape, and the blade portion has a slightly thin blade but has a substantially real cross section. And it gets thinner and lighter as you go to the sword. The warp of the blade is about 1% of the total length and is almost straight. Mainly used for Kendo practice. Length is 102cm. The total weight is about 500 g. (See Figure 1)
もう一つは、素振り用に使用するため、筋力アップを目的として全体の重量を重くしている物、あるいは柄の部分は細いが刀身部分を重くしている物。この場合も柄の断面は瓜実形をなし刀身の反りは無い。長さは色々有り全体の重量は、１kｇを超える。（図２参照） The other is used for swinging, so that the overall weight is increased for the purpose of increasing strength, or the handle is thin but the blade is heavy. Also in this case, the cross section of the handle has a real shape and there is no warping of the blade. There are various lengths, and the total weight exceeds 1 kg. (See Figure 2)
以上に述べた従来の木刀は、単に剣道形の練習及び昇段審査時の剣道形の披露に使用するもの。（剣道形の練習も意義はある。）あるいは筋力アップを目的として素振り用に作られたものである。先端に行くほど刀身の断面を太くした木刀が提案されている。（例えば特許文献１参照）この木刀は確かに筋力アップには効果があるが剣道技術のアップはあまり期待出来ない。 The conventional wooden swords described above are simply used for practicing kendo form and showing off the kendo form at the stage of grading. (Kendo practice is also meaningful.) Or it was made for swinging for the purpose of improving muscular strength. A wooden sword with a thicker cross section has been proposed. (For example, see Patent Document 1) Although this wooden sword is certainly effective in improving muscular strength, it cannot be expected to improve kendo technology.
現代の剣道は竹刀を使った打突により勝敗が決する。勝敗を決める有効打突は、力まかせの強打ではなく、竹刀の刃とする部分が正確に相手の打突部位にあたり、そして打った腕は即座に伸びていなければならない。先に述べた従来の木刀ではこの技術を養う事は出来ない。 In modern Kendo, victory or defeat is decided by hitting with a bamboo sword. The effective hit that determines victory or defeat is not a powerful hit, but the part of the bamboo sword's blade must be the exact hitting part of the opponent and the struck arm must extend immediately. The conventional wooden swords mentioned earlier cannot cultivate this technique.
本発明は、このような有効打突技術を向上させるべく考案した画期的な素振り用の木刀である。 The present invention is an epoch-making wooden sword devised to improve such an effective impact technology.
そして本発明は、上記目的を達成する為に、剣道家達が従来から持つ木刀に対する常識的概念を覆し、柄の部分の断面は正円で直径は竹刀のサイズとほぼ同じとし剣先に行くほど大きく、そして重くする。（柄以外の刀身の断面は正円でなくともよい。）刀身の反り、つまり木刀の曲がりは、木刀の全長の２％から１８％の範囲とする。 And in order to achieve the above-mentioned object, the present invention reverses the conventional concept of kendo swordsmen, and the cross section of the handle is a perfect circle, the diameter is almost the same as the size of the bamboo sword, and the larger it goes to the sword tip. And heavier. (The cross section of the blade other than the handle does not have to be a perfect circle.) The warp of the blade, that is, the bending of the wooden blade, is in the range of 2% to 18% of the entire length of the wooden blade.
上記課題解決手段による作用は次の通りである。
木刀を持って素振りをし、打突部位で瞬時に木刀を止めた時、柄の断面が正円であれば木刀が手の内で滑り回りやすい。又、木刀に大きな反りがあれば尚回りやすくなる。そして剣先が重いと一層回りやすくなる。木刀が回ってしまえば刃筋は傾き正しい打突が出来ない。
The effect | action by the said problem-solving means is as follows.
When swinging with a wooden sword and stopping the wooden sword instantly at the striking part, if the cross section of the handle is a perfect circle, the wooden sword will easily slide around in the hand. Also, if there is a large warp in the wooden sword, it will be easier to turn. And if the sword tip is heavy, it will be easier to turn. If the wooden sword turns, the blade will not tilt correctly.
本発明の木刀で正しい素振りをする為には打突を止めた瞬時、左手の小指と薬指で強く柄を握る力と両手で強く正しく柄を絞る力が従来の木刀に比べて数倍必要になる。その為、この発明の木刀で素振りすることにより一段と正しい打突技術が身に付く。尚、この木刀で素振りをする時、剣道試合用の籠手をはめて行うと手の内で木刀が一層滑りやすく本木刀を使った素振りの効果が一段と高まる。 In order to perform the correct swing with the wooden sword of the present invention, the moment when the strike is stopped, the force to grip the handle strongly with the little finger and ring finger of the left hand and the force to squeeze the handle correctly with both hands are required several times compared to the conventional wooden sword. Become. For this reason, the correct hitting technique can be acquired by swinging with the wooden sword of the present invention. When swinging with this wooden sword, if you put a sword for a kendo match, the wooden sword will be more slippery in the hand, and the effect of swinging with the main sword will be further enhanced.
上記課題解決手段による技術的効果は次の通りである。
本発明木刀による左右面、左右胴、籠手の素振りをする事により、左手小指及び薬指の竹刀を握る力を強くし、打突した時の両手の絞りが強く正しくなり、竹刀を使った剣道試合において狙った相手の部位を正しい刃筋ですばやく正確に打突出来、打突後はまっすぐに腕を伸ばすことが出来る。
The technical effects of the above problem solving means are as follows.
By swinging the left and right sides, left and right torso, and gauntlet with the wooden sword of the present invention, the strength of gripping the left knives and ring fingers of the bamboo sword is strengthened. You can quickly and accurately hit the opponent's part that you aimed at in the game with the correct blade, and you can extend your arm straight after the hit.
すなわち剣道で言う“手の内”が一段と向上する。そのため言うまでもなく打突速度が速くなり、打突後瞬時に手、腕、肩の力が抜け素早く次の動作に移る事が出来る。 In other words, “inside the hand” in kendo is further improved. For this reason, it goes without saying that the impact speed increases, and after the impact, the power of the hand, arm, and shoulder is released and the next action can be quickly started.
本発明は、長年剣道を続けてきた人でも実際に本木刀を振って見なければ納得出来ない。想像だけではまず思いつくことは出来ない。 The present invention cannot be convinced even by a person who has continued Kendo for many years without actually waving a real sword. I can't come up with an imagination alone.
又、この技術は居合道の訓練にも、又、柄の部分を長くする事により薙刀の訓練用として応用する事が出来る。 This technique can also be applied to Iaido training and for the training of katana by making the handle length longer.
本発明木刀の柄の断面直径は、小学生から大人までが使用する各サイズの竹刀の柄の断面直径とほぼ同径とし、正円とする。刀身は大きく反り（全長の２％から１８％）、剣先に行くほど太くする。（当然剣先に行くほど重くなる。）刀身部分の断面形状は特に規定しないが、考えられる断面形状を図３に示す。木刀の全長は使用する者の体力と技量に合わして５０ｃｍから２００ｃｍとし、木刀の全重量も同様に２００ｇから１５００ｇとする。 The cross-sectional diameter of the handle of the wooden sword of the present invention is approximately the same as the cross-sectional diameter of the bamboo sword handle of each size used by elementary school students to adults, and is a perfect circle. The blade is greatly warped (from 2% to 18% of the total length) and becomes thicker as it goes to the tip of the sword. (Of course, the heavier the sword is, the heavier it is.) The cross-sectional shape of the blade part is not particularly defined, but a possible cross-sectional shape is shown in FIG. The total length of the wooden sword is 50 cm to 200 cm according to the physical strength and skill of the user, and the total weight of the wooden sword is also 200 g to 1500 g.
上記柄の断面、刀身の反り、剣先の重さ、全長そして全重量を組み合わせて製作することで使用者に最適の長さ、重さ及びバランスを有する木刀が選択できる。 By combining the cross section of the handle, the warp of the blade, the weight of the sword, the total length, and the total weight, a wooden sword having the optimum length, weight and balance for the user can be selected.
