Description

本考案は、和楽器に使用する絃に関するものである。   The present invention relates to a kite used for a Japanese musical instrument.

絃を使用する楽器において、絃の性能が重要であることはいうまでもなく、和楽器についても事情は他の楽器と同様である。例えば13絃の箏、いわゆる琴について、絃の重要な要素は、音質、余韻、音量、耐久性であり、従来の絹製絃は前2者を満たすものの、音量と耐久性に問題があるとされていた。これに対してナイロンやポリエステルを素材とする絃の場合、音質、余韻の点で不十分であるとの評価であった。   It goes without saying that the performance of a kite is important in a musical instrument that uses a kite, and the situation is similar for other Japanese musical instruments. For example, for the so-called koto of 13 絃, the important elements of 絃 are sound quality, reverberation, volume, and durability. Although the conventional silk cocoons satisfy the former two, there are problems with volume and durability. It had been. On the other hand, in the case of a bag made of nylon or polyester, it was evaluated that the sound quality and reverberation were insufficient.

一方、一般的な弦楽器であるギターの弦について見ると、実開平6−47996号は、ピアノ線芯に巻いた銅線巻層の外面に、銅線にポリウレタン塗装した塗色金属線を巻き設けるギター弦を開示している。同考案は金属弦の振動伝播を干渉、妨害することなく、安定した音質の良い音色を出すことができ、また塗色によってファッション性及び耐久性向上に寄与することができるように、銅線にポリウレタン塗装した塗色金属線を巻き設けたものである。   On the other hand, looking at the strings of a guitar, which is a general stringed instrument, Japanese Utility Model Publication No. 6-47996 winds a painted metal wire coated with polyurethane on a copper wire around the outer surface of a copper wire wound around a piano wire core. Disclosure of guitar strings. The same wire can be used for copper wire so that it can produce stable and high-quality timbres without interfering or interfering with the vibration propagation of metal strings, and can also contribute to improving fashionability and durability through paint colors. A coated metal wire coated with polyurethane is wound around.

また米国特許第6835454号の発明は、フッ素系高分子を用いて弦の表面にコーティングを施したもので、弦表面における摩擦係数を減少させ、かつまた弦構造内部における摩擦をも減少させるというものである。しかし、これらは基本的に巻線構造を持つもので、和楽器用の撚り線構造を有する、例えば箏の絃に求められている性能向上には応用し難い。   The invention of US Pat. No. 6,835,454 is a coating on the surface of a string using a fluoropolymer, which reduces the coefficient of friction on the string surface and also reduces the friction inside the string structure. It is. However, these basically have a winding structure, and have a stranded wire structure for a Japanese musical instrument, for example, it is difficult to apply to the performance improvement required for a kite.

実開平6−47996号ACT 6-47996 米国特許第6835454号US Pat. No. 6,835,454

本考案は上記の事情に着目してなされたもので、その課題は、音質、余韻を改善し、野外演奏に耐える音量と音色を併有した和楽器用絃を提供することである。   The present invention has been made paying attention to the above-mentioned circumstances, and its problem is to provide a Japanese musical instrument kit having improved sound quality and reverberation and having both a volume and a tone color that can withstand outdoor performance.

前記の課題を解決するため本考案は、和楽器に使用する絃として、フッ素化合物より成るモノフィラメントを使用し、上記のモノフィラメントを複数本撚り合わせた撚り糸構造を有し、上記の撚り糸を撚り止め手段により固定するという手段を講じたものである。   In order to solve the above-mentioned problems, the present invention uses a monofilament made of a fluorine compound as a bag used for a Japanese musical instrument, has a twisted yarn structure in which a plurality of the above-mentioned monofilaments are twisted together, and is a means for twisting the above-mentioned twisted yarn. It is a measure to fix by.

本考案に係る和楽器用絃は、フッ素化合物より成るモノフィラメントを素材とするものであり、フッ素化合物としては、フルオロカーボン(ポリフッ化ビニリデン)などが望ましい。この種のフッ素化合物は、比重がポリエチレンの0.97、ナイロンの1.14〜1.16などと比較して、格段に大きく、例えば或る会社製品の場合、小さくても1.78という高比重を示すとともに、高比重素材の中でも優れた音質を有している。   The instrument for a Japanese musical instrument according to the present invention is made of a monofilament made of a fluorine compound, and the fluorine compound is preferably fluorocarbon (polyvinylidene fluoride). This type of fluorine compound has a specific gravity that is significantly higher than 0.97 for polyethylene, 1.14 to 1.16 for nylon, etc. In addition to showing specific gravity, it has excellent sound quality among high specific gravity materials.

このフッ素化合物から原糸を引いてモノフィラメントを形成し、このモノフィラメントを撚り糸機により撚り合わせ、撚り糸構造を持った撚り糸を形成し、さらにこの撚り糸を撚り止め手段により、撚りを固定する。撚り止め手段としては接着その他各種の方法があるが、本考案では熱加工を最良とする。熱加工は、モノフィラメントを撚り合わせた状態において、モノフィラメントの軟化点以上の温度に加熱して軟化させ、その後冷却するもので、熱加工により、モノフィラメントが直線から撚り糸構造の曲線に曲げられた状態に賦形され、かつモノフィラメント同士がからみ合った状態で固定される。   A monofilament is formed by pulling a raw yarn from the fluorine compound, the monofilament is twisted by a twisting machine to form a twisted yarn having a twisted yarn structure, and the twist is fixed by a twisting stop means. There are various other methods for preventing twisting, but in the present invention, thermal processing is best. Thermal processing is a process in which monofilaments are twisted together, heated to a temperature above the softening point of monofilaments, softened, and then cooled. It is shaped and fixed with the monofilaments intertwined.

熱加工された本考案の和楽器用絃は数条のものが一体となって、1本の絃を形成している。なお、一体化している数条のモノフィラメントは相互に接着した状態になっていても良いし、また、なっていなくても良い。   Heat-processed Japanese musical instrument musical instruments are combined into several pieces to form a single musical instrument. In addition, several monofilaments integrated may be in a state of being bonded to each other, or may not be formed.

本考案は以上の如く構成されかつ作用するものであるから、高比重の素材の撚り合わせ構造により音量の増大と、余韻の向上が見られ、かつフッ素化合物製モノフィラメントから成ることにより優れた音質を発揮し得るもので、特に大きな音量と和楽器の音質を保持できることにより、野外コンサートや大ホール等での演奏に有効である。   Since the present invention is constructed and works as described above, the twisted structure of high specific gravity material increases the sound volume and improves the reverberation, and is made of a fluorine compound monofilament for superior sound quality. It can be used for performances in outdoor concerts, large halls, etc., because it can maintain particularly high volume and sound quality of Japanese instruments.

以下図面を参照して本考案をより具体的に説明する。図1は本考案に係る和楽器用絃10の1例を示すもので、この和楽器用絃10はモノフィラメント11を複数本撚り合わせた撚り糸構造12を有している。   Hereinafter, the present invention will be described more specifically with reference to the drawings. FIG. 1 shows an example of a Japanese musical instrument scissor 10 according to the present invention. This Japanese musical instrument scissor 10 has a twisted yarn structure 12 in which a plurality of monofilaments 11 are twisted together.

例示のモノフィラメント11は、クレハ化学製のフルオロカーボン(ポロフッ化ビニリデン:PVDF)を素材として、原糸を引き、形成したもので、太さとしては、直径が0.2〜1.2mmの範囲のものである。図1の例では、同一の太さのモノフィラメント11を4本撚り合わせ、さらにその状態にて100〜200℃で熱加工して本考案の和楽器用絃10が形成されている。温度は、絃を通す速度によって変わり、また、絃の硬軟によっても変わって来る。   The illustrated monofilament 11 is formed by drawing a raw yarn from Kureha Chemical's fluorocarbon (polyvinylidene fluoride: PVDF) and having a diameter in the range of 0.2 to 1.2 mm. It is. In the example of FIG. 1, four monofilaments 11 having the same thickness are twisted and further heat-processed at 100 to 200 ° C. in this state to form the Japanese musical instrument scissors 10 of the present invention. The temperature changes depending on the speed at which the cocoon is passed, and also changes depending on the hardness of the cocoon.

本考案の和楽器用絃10において、太さ17.5番のものを琴用として製造し、また太さ13−3番のものを三味線用として製造し、これらを従来の絃と比較するため音量変化を測定記録する実験をおこなった。図2、図3に実験結果を示す。   In the Japanese musical instrument kite 10 of the present invention, the one with a thickness of 17.5 is manufactured for koto, the one with a thickness of 13-3 is manufactured for a shamisen, and these are compared with a conventional kite An experiment was conducted to measure and record changes in volume. The experimental results are shown in FIGS.

図2は、Aが本考案の和楽器用絃10の音量変化、Bが従来のテトロン製の琴の絃の音量変化を示す。図2のA、Bを比較すると、Aの方が発音の立ち上がりが素早くしかも長秒時にわたって持続する。このため強度(縦軸の振幅)は差があまりないにも拘らず、音量としては本考案の和楽器用絃10の方が著しく大であることがわかる。   In FIG. 2, A shows the volume change of the Japanese musical instrument kite 10 of the present invention, and B shows the volume change of the conventional Tetoron koto kite. Comparing A and B in FIG. 2, the sound generation of A is quicker and continues for a long time. For this reason, although the intensity (amplitude on the vertical axis) is not much different, it can be seen that the sound volume of the Japanese musical instrument kit 10 of the present invention is remarkably large.

図3は、図2と同様Aが本考案の和楽器用絃10、Bが従来のナイロン製の三味線の絃の音量変化を示す。この実験例を比較した場合でも、Aの方が発音の立ち上がりが早く長秒時持続していることが分かる。音量も従ってAの方が著しく大である。なお、横軸は秒(sec)を単位とする時間、縦軸はデシベル(dB)を単位とする音圧又は音の強さのレベルを示しており、全図共通である。   FIG. 3 shows the change in volume of the Japanese musical instrument scissors 10 according to the present invention, and FIG. Even when this experimental example is compared, it can be seen that the sound generation of A is faster and lasts for a longer time. Therefore, the volume of A is remarkably large. The horizontal axis represents time in seconds (sec), and the vertical axis represents sound pressure or sound intensity level in decibels (dB), which is common to all drawings.
