A trainee positions his or her hand along this handle in moving the bow during the training.

Description

本発明は弦楽器演奏のトレーニングに関するものである。 The present invention relates to training for playing stringed instruments.

弦楽器は、弓の毛と楽器の弦の摩擦によって音が出る。けれど、良い音を出すには弓の毛を弦に垂直に交わるように演奏し、上から一定の圧力をかけながら動かす必要がある。右手に弓を持ち常に弦に対して垂直に交わるように往復させるのであるが、弓は直線運動であるのに対し、人体の手の構造上、肘を屈伸させると手先は円を描いてしまうので右手の手首と指を上手に使って、円運動を直線運動に変換させるテクニックが必要である。円運動を直線運動に変換するという身体にとって不自然な作業するには、手や指の関節が柔軟でないとできない。筋肉の硬い人が苦心するところであり、十分にそれができるようになるための訓練には大変な根気と努力が必要である。
この訓練を助けるための道具として先行技術文献特開２００８―９０２９１号公報は、バイオリンを模った本体上の弓案内体にガイドされた弓を移動させることにより運弓の練習を行うものである。 A stringed instrument produces sound by friction between the bow hair and the string of the instrument. However, in order to produce a good sound, it is necessary to play the bow hair perpendicularly to the string and move it with a certain pressure from above. While holding a bow in the right hand and always reciprocating so as to intersect perpendicularly to the string, the bow is a linear motion, but due to the structure of the human hand, the elbow is bent and stretched, and the hand draws a circle Therefore, a technique for converting the circular motion into a linear motion using the wrist and fingers of the right hand is necessary. In order to work unnaturally for the body to convert circular motion into linear motion, the joints of hands and fingers can only be flexible. A person with hard muscles is struggling, and training to be able to do it sufficiently requires great patience and effort.
As a tool for assisting this training, Japanese Patent Laid-Open No. 2008-90291 discloses a practice of bowing by moving a bow guided by a bow guide on a body imitating a violin. .

特開２００８―９０２９１号公報JP 2008-90291 A

前記の運弓練習具では、弓を弓案内体のガイドによって移動させることにより、ボーイング時の右手の柔軟性を図るものであったが、弓を持つ右手の手首の位置は固定されており、弓の移動による手首の角度の調節については練習できなかった。 In the bowing practice tool described above, the flexibility of the right hand during bowing was achieved by moving the bow with the guide of the bow guide, but the position of the wrist of the right hand with the bow is fixed, I couldn't practice adjusting the wrist angle by moving the bow.

本発明の弦楽器のトレーニング器は、バイオリンを模った本体と、本体上で摺動させる弓と、前記弓の端部近傍に回転可能な持ち手とを備えて、右手で持ち手を把持して弓を弓案内体にガイドさせてトレーニングする。 A stringed instrument training device of the present invention comprises a main body imitating a violin, a bow that slides on the main body, and a handle that can be rotated near the end of the bow, and grips the handle with the right hand. Train with a bow guide.

本発明は、持ち手の軸回転可能にしたので単に棒状の弓とは異なり右手首の回転運動をする事ができ、右手に弦楽器のボーイングの軌道を覚え込ませるばかりではなく、正しいボーイングに必要な手首の動きをトレーニングする事ができる。又筋肉の弓の移動時に手首を回転させる事で手首に柔軟性を与えることができる。 The present invention makes it possible to rotate the handle's shaft so that it can rotate the right wrist, unlike a stick-shaped bow. You can train your wrist movements. In addition, the wrist can be made flexible by rotating the wrist during the movement of the muscular bow.

本発明の実施例を図に基づいて説明すると図１に示すようにバイオリンを模った本体１の胴体部１aに弓２がバイオリンを横切る位置に回動体３を設ける。 An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a rotating body 3 is provided at a position where a bow 2 crosses a violin on a body portion 1a of a main body 1 imitating a violin.

図４は図１に示すＡ―Ａ断面であり本体１に設けられた前記回動体３は図４に示すように本体長手方向の中央部近傍に設けられた回動体回転軸７に軸支されていて、回動体回転軸７を中心に図の前後方向に軸回転する。（図１の回動体回転方向を参照） 4 is a cross-sectional view taken along the line AA shown in FIG. 1. The rotating body 3 provided in the main body 1 is pivotally supported by a rotating body rotating shaft 7 provided near the center in the longitudinal direction of the main body as shown in FIG. Thus, the shaft rotates in the front-rear direction of the drawing around the rotating body rotation shaft 7. (Refer to the rotating direction of the rotating body in Fig. 1)

さらに弓案内体４を前記回動体３に載置する。前記弓案内体４は、貫通孔4aを有し,
この貫通孔に弓２を挿入し、貫通孔４aに弓２がガイドされて図１に示すように左右に、摺動させたりする事ができる。 Further, the bow guide 4 is placed on the rotating body 3. The bow guide 4 has a through hole 4a,
The bow 2 can be inserted into the through hole, and the bow 2 can be guided to the through hole 4a and slid left and right as shown in FIG.

本体１には凸部５が固定されておりこの凸部５に図４に示す固定具６を介して回動体３を固定したり開放したりすることができる。 A convex portion 5 is fixed to the main body 1, and the rotating body 3 can be fixed to or released from the convex portion 5 via a fixture 6 shown in FIG. 4.

さらに、弓案内体４には弓固定手段８がネジ込まれており、弓固定手段８を調節することにより弓案内体４に弓２を固定する事ができる。 Further, a bow fixing means 8 is screwed into the bow guide body 4, and the bow 2 can be fixed to the bow guide body 4 by adjusting the bow fixing means 8.

図１において弓２に段差部を設け弓２の端部近傍２aに台１３が台用ロックネジ（固定手段）１５で固定されている。
図２に示すように台１３にはロック機構を有する車輪軸（軸）１２が設けられており、持ち手９の車輪孔１１に挿入することにより持ち手９は図１に示す方向に回転可能である。 In FIG. 1, a step is provided on the bow 2, and a table 13 is fixed to the vicinity 2 a of the end of the bow 2 by a table lock screw (fixing means) 15.
As shown in FIG. 2, the base 13 is provided with a wheel shaft (shaft) 12 having a lock mechanism, and the handle 9 can be rotated in the direction shown in FIG. 1 by being inserted into the wheel hole 11 of the handle 9. It is.

さらに持ち手９は支持部9aに設けられた車輪孔１１にロック機構を有する車輪軸１２で取り付けられている。 Further, the handle 9 is attached to a wheel hole 11 provided in the support portion 9a by a wheel shaft 12 having a lock mechanism.

図５は図２のＢ−Ｂ断面であり、車輪軸１２はネジを有しとナット１０のネジで固定されると持ち手の回転を固定する事ができる。
前記持ち手９は、ロック機構を有する車輪支持軸１２により、押圧の調節によってロック状態、アンロック状態にできる。 FIG. 5 is a cross-sectional view taken along the line B-B in FIG. 2. When the wheel shaft 12 has a screw and is fixed with the screw of the nut 10, the rotation of the handle can be fixed.
The handle 9 can be brought into a locked state and an unlocked state by adjusting the pressure by a wheel support shaft 12 having a lock mechanism.

本発明の弦楽器のトレーニング器は、回動体３を固定あるいは回転可能にしたり、弓案内体４内の弓の移動を固定したり、持ち手９を固定あるいは回転可能にしたり台１３を回転可能あるいは固定したりしてトレーニングすることができる。 The training apparatus for a stringed instrument of the present invention can fix or rotate the rotating body 3, fix the movement of the bow in the bow guide body 4, fix or rotate the handle 9, or rotate the table 13. It can be fixed and trained.

次に動作について説明する。トレーニング者は図６に示すように本体１を構え、弓案内体４に弓２を挿入して、持ち手９を右手で持ち弓２を弓案内体４に沿って移動させて、弓２の移動時に持ち手９を上下方向に回転させながらトレーニングを行う。トレーニングは弓２の移動と共に持ち手９の角度を変える。すなわち手首の角度を変えながら行う。このトレーニングにより弓の位置によって、手首と弓の角度を上下方向に円弧上に変える事で弓と弦とが直角に交わり正しい弓の軌道を学ぶ事ができる。持ち手９の車輪孔１１とロック機構を有する車輪軸１２とはロック機構で固定する事により持ち手９の回転位置を固定する事もできる。
弓が弦と垂直に交わりながら演奏するためには手が感覚的に弓の軌道を覚えただけでは不十分である。そのためには演奏中、弓の位置によって手指の弓と交わる角度を必要に応じて変えたり、指を曲げたりできる柔軟性がなければ、正しい弓の軌道で演奏する事は難しい。また、弓の先の部分、真ん中、元によって、圧力のかけ方を調整しながら演奏することも必要である。そのためには４本の指でバランスをとる必要がある。指と弓の１点を接触させたまま手指を振れ動きの運動を即す事ができる。 Next, the operation will be described. As shown in FIG. 6, the trainee holds the main body 1, inserts the bow 2 into the bow guide 4, holds the handle 9 with the right hand, moves the bow 2 along the bow guide 4, Training is performed while the handle 9 is rotated up and down during movement. Training changes the angle of the handle 9 as the bow 2 moves. That is, it is performed while changing the wrist angle. This training allows you to learn the correct bow trajectory by crossing the bow and string at right angles by changing the angle of the wrist and bow vertically on the arc, depending on the bow position. The rotational position of the handle 9 can also be fixed by fixing the wheel hole 11 of the handle 9 and the wheel shaft 12 having the lock mechanism with the lock mechanism.
It is not enough for the hand to feel the bow trajectory sensuously in order to perform while the bow crosses the string vertically. For that purpose, it is difficult to perform in the correct bow trajectory without the flexibility to change the angle of the finger bow depending on the position of the bow as necessary or bend the finger during the performance. It is also necessary to perform while adjusting the way pressure is applied depending on the tip, middle and origin of the bow. For that purpose, it is necessary to balance with four fingers. You can make your fingers swing and move with your finger and bow in contact.

弓２は弓案内体４を通過する部分から下側に折れ曲がって段差が設けられて、その段差の部分に台１３が取り付けられている。台１３に持ち手９が取り付けられているので持ち手９は弓案内体４の弓の位置とほぼ同じ高さになり、通常のバイオリンの演奏時と同じ感覚でトレーニングが行える。持ち手９と台１３が共に回転可能であれば、弓２は三次元的に動くことも可能であるが、持ち手９を三次元的に動かせる球面上の軸受けを用いてもよい。 The bow 2 is bent downward from a portion passing through the bow guide body 4 to be provided with a step, and a table 13 is attached to the step. Since the handle 9 is attached to the base 13, the handle 9 is almost the same height as the bow of the bow guide 4, and training can be performed with the same feeling as when playing a normal violin. If both the handle 9 and the base 13 are rotatable, the bow 2 can be moved three-dimensionally, but a spherical bearing that can move the handle 9 three-dimensionally may be used.

台１３は台用ロックネジ１５を緩めることにより、回転させる事ができ角度を調節した後、台用ロックネジ１５で固定し、その角度位置で持ち手９を弓２の移動とともに上下方向に変えてトレーニングする。 The table 13 can be rotated by loosening the table lock screw 15, and after adjusting the angle, the table 13 is fixed with the table lock screw 15, and the handle 9 is moved up and down with the movement of the bow 2 at that angle position for training. To do.

弓案内体４の弓固定手段８のネジによって弓２を固定する事ができ弓２を固定した状態で持ち手９を上下方向に円弧上に変えてトレーニングを行う事もできる。なお、弓案内体４を取り付けている回動体３も回動体固定具６のネジを緩めることにより回転させる事ができ弓２の移動に伴って弓案内体４を円弧上に回転してトレーニングを行える。又、回動体固定具６にネジを締めることにより回動体３を任意の角度で固定する事もできる。 The bow 2 can be fixed by the screw of the bow fixing means 8 of the bow guide 4 and the training can be performed by changing the handle 9 up and down on the arc while the bow 2 is fixed. The rotating body 3 to which the bow guiding body 4 is attached can also be rotated by loosening the screw of the rotating body fixing tool 6, and as the bow 2 moves, the bow guiding body 4 is rotated on an arc to perform training. Yes. Further, the rotating body 3 can be fixed at an arbitrary angle by tightening a screw on the rotating body fixing tool 6.
