Description

本発明は、擦弦楽器の構成部品である魂柱に関する。 The present invention relates to a sound post, which is a component of a bowed string instrument.

魂柱を作成する場合、楽器ボディー内で表板と裏板の魂柱の当たる部分のそれぞれの内面形状に正確に一致するように成形し、魂柱端面と表板および裏板との間に隙間が無いようにすると同時に、表板と裏板に挟まれた状態で自立するようにセットするため、魂柱の長さを適正にする必要がある。それらの正確な確認およびセッティングは作業者の技能に依存している。 When creating a sound post, shape it so that it exactly matches the inner surface shape of each part of the front plate and back plate where the sound post hits, and between the end face of the sound post and the front plate and back plate. At the same time as making sure there are no gaps, it is necessary to make the length of the sound post appropriate in order to set it so that it can stand on its own while being sandwiched between the front and back plates. Their exact confirmation and setting depends on the skill of the operator.

本発明は、魂柱を楽器ボディー内にセットする際に必要とする適正な魂柱の長さ、そして表板と魂柱および裏板と魂柱とのそれぞれの接し面の正確な合わせの成形において、技術的な難しさの軽減を図るとともに、それらに伴う作業時間の短縮を提供することにある。 The present invention is the proper length of the sound post required to set the sound post in the instrument body, and the exact alignment of the contact surfaces of the front plate and the sound post and the back plate and the sound post. In the present invention, it is intended to reduce technical difficulties and to provide a reduction in working time associated therewith.

魂柱の両端面に、端面と同じ形状のコルク板を接着することにより、表板と魂柱および裏板と魂柱との間に挟まれたコルク板の厚み方向の変形を利用して、隙間をなくすと同時に自立するための適正な長さを得る。 By adhering cork plates of the same shape as the end faces to both ends of the sound post, the deformation in the thickness direction of the cork plate sandwiched between the front plate and the sound post and the back plate and the sound post is used. At the same time as eliminating the gap, obtain an appropriate length for self-reliance.

魂柱の長さ、そして表板および裏板と魂柱との接し面の合わせをコルク板の変形を利用することにより厳密な調整を必要とせず、また魂柱の端面が柔軟性のあるコルク素材のため魂柱を立てる際のボディー内面での表板および裏板への当たりが柔らかく、従来の魂柱端面の木部エッジが当たる状況よりもセッティングが容易である。 The length of the sound post and the alignment of the contact surface between the front and back plates and the sound post do not require strict adjustment by utilizing the deformation of the sound post, and the end face of the sound post is flexible cork. Because of the material, the contact with the front and back plates on the inner surface of the body when erecting the sound post is soft, and it is easier to set than the conventional situation where the wood edge of the end face of the sound post hits.

魂柱を作成するにあたり、楽器に適した大きさの材料を用意し、楽器ボディー内のセット場所に表板と裏板に挟まれた状態で自立するための適正な長さ、そして表板および裏板と魂柱が接する部分のそれぞれの魂柱端面を、その接し面に隙間が生じないように加工する必要がある。 In creating the sound post, prepare a material of a size suitable for the instrument, set it in the instrument body, and have an appropriate length to stand between the front and back plates, and the front and back plates. It is necessary to process the end faces of each sound post at the part where the back plate and the sound post meet so that there is no gap in the contact surface.

従来技術では、魂柱の適正な長さ及び隙間が生じないための端面の調整のために魂柱の加工およびセッティングを繰り返し試行し、時間と技能を要して正しい魂柱３を完成させるが、本実施例では、予め短くした魂柱用材料２の両端面にコルク板１をそれぞれ貼付し、コルク板１の柔軟性を利用して、魂柱の適正な長さに許容の幅を得ると同時に表板および裏板と魂柱端面の接する部分の合わせに関しても厳密性を必要としない。また、セッティングは魂柱の両端面が柔軟性を持ったコルク素材のため従来よりも行いやすく作業時間の短縮を得ることが期待できる。 In the prior art, the sound post is repeatedly processed and set in order to adjust the proper length of the sound post and the end face so that no gap is created, and it takes time and skill to complete the correct sound post 3. In this embodiment, the cork plates 1 are attached to both end faces of the sound post material 2 shortened in advance, and the flexibility of the cork plate 1 is used to obtain an allowable width for the appropriate length of the sound post. At the same time, strictness is not required for the alignment of the contact points between the front and back plates and the end face of the sound post. In addition, the setting is made of cork material with flexibility on both ends of the sound post, so it is easier to set than before and it can be expected that the work time will be shortened.

従来技術と同様に楽器ボディー内で魂柱が自立するために必要な長さを予測し、両端面に貼付するコルク板１の厚み及び柔らかさを考慮して短くした魂柱用材料２を作成する。この時に、魂柱の両端面は接する表板および裏板の内面形状に概ね一致する程度でよい。コルク板の厚みは、薄すぎると柔軟性による変形を得られず、また厚すぎるとセッティングが不安定になるため１ｍｍ～３ｍｍとする。魂柱用材料２の加工が終了した後、魂柱用材料２と両端面用のコルク板１をそれぞれ接着剤で貼り付ける。 As in the conventional technology, the length required for the sound post to stand on its own in the instrument body is predicted, and the material 2 for the sound post shortened in consideration of the thickness and softness of the cork plate 1 to be attached to both end faces is created. do. At this time, both end faces of the sound post need only be substantially the same as the inner surface shapes of the front plate and the back plate that are in contact with each other. If the thickness of the cork plate is too thin, deformation due to flexibility cannot be obtained, and if it is too thick, the setting becomes unstable, so the thickness is set to 1 mm to 3 mm. After the processing of the sound post material 2 is completed, the sound post material 2 and the cork plates 1 for both end faces are attached with an adhesive.
