本考案は鍵盤楽器における口棒の改良に関す
る。[Detailed Description of the Invention] The present invention relates to an improvement of the mouth bar of a keyboard instrument.
従来の鍵盤楽器、例えば第１図に示す縦型ピア
ノにおいて、側板１に固着された腕木２と下面に
設けた棚板３上に配設した鍵盤４と左右の拍子木
５の前面に配して棚板３の下方から結着してなる
構成の口棒６は木材のムク又は合板からなり、第
２図に示すように目にふれる表皮部分ａ・ｂ・ｃ
をを塗装又は化粧板を貼付して仕上げていたが、
裏面ｄ、棚板３への取付面ｅは何等の処理もされ
ていなかつた。このため水分の吸着に伴う体積変
化により、反り・ねじれ及び塗膜割れ・化粧板は
がれ等が多発していた。 In a conventional keyboard instrument, for example, the vertical piano shown in FIG. The opening rod 6, which is connected from the bottom of the shelf board 3, is made of solid wood or plywood, and the visible skin parts a, b, and c are shown in Fig. 2.
It was finished by painting or pasting a decorative board, but
The back surface d and the mounting surface e to the shelf board 3 had not been subjected to any treatment. As a result, warping, twisting, cracking of the paint film, peeling of the decorative board, etc. frequently occurred due to changes in volume due to moisture adsorption.
又、口棒６の形状は第２図に示すように装飾形
状を成すため加工にかなり工数がかかり均一化が
極めて困難である等の欠点を有していた。 In addition, the shape of the opening bar 6 is decorative as shown in FIG. 2, and therefore it requires a considerable number of man-hours to process and has the disadvantage that it is extremely difficult to make it uniform.
更に、従来の口棒６は固形体（ムク材）で成形
されていたため、取付が不十分であると演奏時に
演奏音によつて共振する欠点があつた。 Furthermore, since the conventional mouthpiece 6 was molded from a solid material (solid material), it had the disadvantage that if it was not properly attached, it would resonate with the sound played during performance.
本考案は上述の欠点を解決すべくなされたもの
であり、その実施例を説明すると、第３図の鋼板

貼付して形成したものである。 The present invention was made to solve the above-mentioned drawbacks, and to explain its embodiment, a PVC sheet A is thermally bonded to one side of the steel plate B shown in Fig. 3, and the PVC sheet A side is the back side. The steel plate is then formed by pressing or roll forming into the required cross-sectional shape as shown in FIG.
又第５図は本考案の他の実施例を示し、鋼板Ｂ
の片面に塩ビシートＡの代わりに繊毛Ｃを静電植
毛した鋼板である。 Further, FIG. 5 shows another embodiment of the present invention, in which steel plate B
This is a steel plate with cilia C electrostatically flocked on one side of the PVC sheet A instead of the PVC sheet A.
このように本考案によれば、断面形状を制限さ

良もなく大量生産ができると共に演奏音による共
振をも防止出来る口棒を提供することができるも
のである。 As described above, according to the present invention, it is possible to provide a mouth bar that can be machined uniformly without any restrictions on cross-sectional shape, can be mass-produced without defects such as warping or twisting, and can also prevent resonance due to performance sounds. It is something.
