Description

この発明は、電子ピアノなどの鍵盤楽器に用いられる鍵盤構造に関する。   The present invention relates to a keyboard structure used for a keyboard instrument such as an electronic piano.

従来、鍵盤楽器の鍵盤構造においては、特許文献1に記載されているように、複数の鍵の各後端部を複数の鍵の配列方向に沿って連続する共通支持部にそれぞれ薄肉の屈曲部を介して連結して、複数の鍵を所定間隔で配列させることにより、第1〜第3の各鍵ユニットを構成し、この第1〜第3の各鍵ユニットにおける各共通支持部を重ねて合わせて、第1の鍵ユニットにおける複数の鍵の各間に、第2、第3の各鍵ユニットの各鍵を配置し、この状態で各共通支持部をねじ部材によって締め付けて固定することにより、多数の鍵を音階順に配列させた構成のものが知られている。
特開平10−240227
Conventionally, in a keyboard structure of a keyboard instrument, as described in Patent Document 1, each rear end portion of a plurality of keys is thinly bent to a common support portion that is continuous along the arrangement direction of the plurality of keys. The first to third key units are configured by connecting a plurality of keys at predetermined intervals, and the common support portions in the first to third key units are overlapped. In addition, by arranging each key of each of the second and third key units between each of the plurality of keys in the first key unit, in this state, each common support portion is fastened and fixed by a screw member. A configuration in which a large number of keys are arranged in order of musical scale is known.
JP-A-10-240227

このような従来の鍵盤構造では、第1の鍵ユニットにおける複数の鍵の各間に、第2、第3の各鍵ユニットの各鍵を配置させて、第1〜第3の各鍵ユニットの各共通支持部を重ねて合わせ、この状態で各共通支持部をねじ部材によって締め付けると、ねじ部材の頭部と最上部に位置する共通支持部の上面との間に大きな摩擦力が発生し、この摩擦力によって共通支持部にねじ部材の締め付け回転方向への捻じれが発生し、第1〜第3の各鍵ユニットにおける互いに隣接する鍵同士の隙間が変化する。   In such a conventional keyboard structure, the keys of the second and third key units are arranged between the plurality of keys in the first key unit, and the first to third key units are arranged. When each common support part is overlapped and aligned, and each common support part is tightened with a screw member in this state, a large frictional force is generated between the head of the screw member and the upper surface of the common support part located at the top, Due to this frictional force, the common support portion is twisted in the tightening rotation direction of the screw member, and the gap between adjacent keys in the first to third key units changes.

しかしながら、このような従来の鍵盤構造では、ねじ部材の頭部と最上部に位置する共通支持部の上面との間に発生する摩擦力によって、共通支持部にねじ部材の締め付け回転方向への捻じれを発生させて、互いに隣接する鍵同士の隙間を変化させているが、摩擦力だけでは互いに隣接する鍵同士の隙間を十分に且つ正確に修正することができないため、多数の鍵の各隙間が不揃いになるという問題があった。 However, in such a conventional keyboard structure, the common support portion is twisted in the tightening rotation direction of the screw member by a frictional force generated between the head portion of the screw member and the upper surface of the common support portion located at the uppermost portion. The gap between adjacent keys is changed, but the gap between adjacent keys cannot be corrected sufficiently and accurately by frictional force alone. There was a problem that became irregular.

この発明が解決しようとする課題は、互いに隣接する鍵同士の隙間を簡単に且つ正確に修正して、多数の鍵の各隙間を均一にすることができる鍵盤構造を提供することである。   The problem to be solved by the present invention is to provide a keyboard structure that can easily and accurately correct the gaps between adjacent keys to make the gaps of a large number of keys uniform.

Mounting holes 18 are provided corresponding to the upper and lower sides.

これにより、変形調整部15は、図10または図13に示すように、ねじ部材14の締め付け力に応じて第1の白鍵共通支持部5における上側傾斜部16と第2の白鍵共通支持部8における下側傾斜部17とが、その両者の傾斜面に沿って相対的に滑ることにより、白鍵4、7の前後方向(図7では左右方向)に変位して、第1、第2の各白鍵共通支持部5、8の一部を白鍵4、7の前後方向(図7では左右方向)に変形させ、これにより各白鍵4、7の配列方向における横振れを修正するように構成されている。 Thereby, as shown in FIG. 10 or FIG. 13, the deformation adjusting unit 15 supports the upper inclined portion 16 and the second white key common support in the first white key common support portion 5 according to the tightening force of the screw member 14. The lower inclined portion 17 of the portion 8 is displaced in the front-rear direction (the left-right direction in FIG. 7) of the white keys 4, 7 by relatively sliding along the inclined surfaces of the both, and the first, first 2 part of each of the white key common support parts 5 and 8 is deformed in the front-rear direction of the white keys 4 and 7 (the left-right direction in FIG. 7), thereby correcting the lateral shake in the arrangement direction of the white keys 4 and 7 Is configured to do.

次に、このような鍵盤構造を組立てる場合について説明する。
この場合には、まず、黒鍵ユニット3を鍵盤シャーシ13上に配置する。このときには、黒鍵ユニット3の黒鍵共通支持部11の下面に設けられた第5位置決め部11bによって鍵盤シャーシ13上に位置決めする。この状態で、黒鍵ユニット3上に第2の白鍵ユニット2を組み付ける。
Next, the case where such a keyboard structure is assembled will be described.
In this case, first, the black key unit 3 is arranged on the keyboard chassis 13. At this time, the black key unit 3 is positioned on the keyboard chassis 13 by the fifth positioning portion 11 b provided on the lower surface of the black key common support portion 11. In this state, the second white key unit 2 is assembled on the black key unit 3.

このときには、図1に示すように、黒鍵ユニット3における複数の黒鍵10の各間に、第2の白鍵ユニット2における複数の白鍵7を配置して、図2に示すように、黒鍵ユニット3の黒鍵共通支持部11上に第2の白鍵ユニット2における第2の白鍵共通支持部8を重ね合わせる。この場合には、黒鍵共通支持部11の上面に設けられた第4位置決め部11aに、第2の白鍵共通支持部8の下面に設けられた第3位置決め部8bを係合させて、黒鍵共通支持部11に対して第2の白鍵共通支持部8を位置決めする。 At this time, as shown in FIG. 1, a plurality of white keys 7 in the second white key unit 2 are arranged between the plurality of black keys 10 in the black key unit 3, and as shown in FIG. The second white key common support portion 8 in the second white key unit 2 is superimposed on the black key common support portion 11 of the black key unit 3. In this case, the fourth positioning portion 11a provided on the upper surface of the black key common support portion 11 is engaged with the third positioning portion 8b provided on the lower surface of the second white key common support portion 8, The second white key common support portion 8 is positioned with respect to the black key common support portion 11.

この後、図1に示すように、黒鍵ユニット3における複数の黒鍵10の各間、および第2の白鍵ユニット2における複数の白鍵7の各間に、第1の白鍵ユニット1における複数の白鍵4を配置して、図2および図6に示すように、第2の白鍵ユニット2における第2の白鍵共通支持部8上に第1の白鍵ユニット1における第1の白鍵共通支持部5を重ね合わせる。この場合にも、第2の白鍵共通支持部8の上面に設けられた第2位置決め部8aに、第1の白鍵共通支持部5の下面に設けられた第1位置決め部5aを係合させて、第2の白鍵共通支持部8に対して第1の白鍵共通支持部5を位置決めする。 Thereafter, as shown in FIG. 1, the first white key unit 1 is placed between the plurality of black keys 10 in the black key unit 3 and between the plurality of white keys 7 in the second white key unit 2. And the first white key unit 1 in the first white key unit 1 on the second white key common support portion 8 in the second white key unit 2 as shown in FIGS. The white key common support portion 5 is overlapped. Also in this case, the first positioning portion 5 a provided on the lower surface of the first white key common support portion 5 is engaged with the second positioning portion 8 a provided on the upper surface of the second white key common support portion 8. Thus, the first white key common support portion 5 is positioned with respect to the second white key common support portion 8.

これにより、図1および図2に示すように、第1の白鍵共通支持部5、第2の白鍵共通支持部8、および黒鍵共通支持部11が重ね合わされて、白鍵4、7および黒鍵10が音階順に配列される。この状態で、図7に示すように、第1の白鍵共通支持部5、第2の白鍵共通支持部8、および黒鍵共通支持部11を複数のねじ部材14によって相互に締め付けて鍵盤シャーシ13上に固定する。このときに、ねじ部材14の締め付け力を調整することにより、互いに隣接する白鍵4、7の隙間Sを修正することができる。 Thereby, as shown in FIGS. 1 and 2, the first white key common support portion 5, the second white key common support portion 8, and the black key common support portion 11 are overlapped to form the white keys 4, 7. The black keys 10 are arranged in the order of the scales. In this state, as shown in FIG. 7, the first white key common support portion 5, the second white key common support portion 8, and the black key common support portion 11 are mutually tightened by a plurality of screw members 14. Fix on the chassis 13. At this time, by adjusting the tightening force of the screw member 14, the gap S between the adjacent white keys 4 and 7 can be corrected.

例えば、図8および図9に示すように、第1、第2の各白鍵ユニット1、2の各白鍵4、7のうち、第1の白鍵ユニット1における一部の白鍵4(例えばFの白鍵)が白鍵4の配列方向の右側に横振れし、これに隣接する第2の白鍵ユニット2における一部の白鍵7(例えばEの白鍵)との間に広い隙間S1が生じている場合には、これらの白鍵4、7(例えばF、Eの各白鍵)に最も近いねじ部材14の締め付け力を調節する。 For example, as shown in FIGS. 8 and 9, among the white keys 4 and 7 of the first and second white key units 1 and 2, a part of the white keys 4 in the first white key unit 1 ( For example, the white key of F) swings to the right in the arrangement direction of the white key 4, and is wide between a part of the white keys 7 in the second white key unit 2 adjacent thereto (for example, the white key of E). When the gap S1 is generated, the tightening force of the screw member 14 closest to the white keys 4 and 7 (for example, F and E white keys) is adjusted.

すなわち、このねじ部材14の締め付け力を調整すると、図10に示すように、その締め付け力に応じて第1の白鍵共通支持部5における上側傾斜部16と第2の白鍵共通支持部8における下側傾斜部17とが相対的に滑り、図11に示すように、第1、第2の各白鍵共通支持部5、8の一部が変形する。 That is, when the tightening force of the screw member 14 is adjusted, as shown in FIG. 10, the upper inclined portion 16 and the second white key common support portion 8 in the first white key common support portion 5 according to the tightening force. As shown in FIG. 11, part of the first and second white key common support portions 5 and 8 is deformed.

このときには、図10に示すように、ねじ部材14の締め付け力によって変形調整部15が白鍵4(例えばFの白鍵)の後方(図10では右側)に向けて変位するので、第1の白鍵共通支持部5の一部が白鍵4(例えばFの白鍵)の後方(図11では上側)に向けて変形する。これに伴って一部の白鍵4(例えばFの白鍵)は、図11に示すように、その配列方向において左側に横振れするように変位する。 At this time, as shown in FIG. 10, the deformation adjusting portion 15 is displaced toward the rear (right side in FIG. 10) of the white key 4 (for example, the F white key) by the tightening force of the screw member 14. A part of the white key common support portion 5 is deformed toward the rear (upper side in FIG. 11) of the white key 4 (for example, the white key of F). Accordingly, some white keys 4 (for example, F white keys) are displaced so as to sway to the left in the arrangement direction, as shown in FIG.

これにより、第1、第2の各白鍵ユニット1、2の各白鍵4、7のうち、第1の白鍵ユニット1における一部の白鍵4(例えばFの白鍵)が白鍵4の配列方向における右側に横振れしていても、その一部の白鍵4(例えばFの白鍵)の横振れによる位置ずれが、図11に示すように、修正される。 As a result, among the white keys 4 and 7 of the first and second white key units 1 and 2, some of the white keys 4 (for example, the F white key) in the first white key unit 1 are white keys. As shown in FIG. 11, even if there is a lateral shake in the right direction in the arrangement direction of 4, the position shift due to the lateral shake of a part of the white keys 4 (for example, the F white key) is corrected.

このため、図8に示すように、第1の白鍵ユニット1における一部の白鍵4(例えばFの白鍵)と、これに隣接する第2の白鍵ユニット2における一部の白鍵7(例えばGの白鍵)との間の隙間S1が広くても、図1に示すように、他の白鍵4、7間の隙間Sと同じ隙間Sに修正することができるので、全ての白鍵4、7間の隙間Sを均一にすることができる。 Therefore, as shown in FIG. 8, a part of the white keys 4 in the first white key unit 1 (for example, the white key of F) and a part of the white keys in the second white key unit 2 adjacent thereto. 7 (for example, the white key of G) can be corrected to the same gap S as the gap S between the other white keys 4 and 7, as shown in FIG. The gap S between the white keys 4 and 7 can be made uniform.

また、図12に示すように、第1、第2の各白鍵ユニット1、2の各白鍵4、7のうち、第2の白鍵ユニット2における一部の白鍵7(例えばEの白鍵)が白鍵7の配列方向における左側に横振れし、これに隣接する第1の白鍵ユニット1における一部の白鍵4(例えばFの白鍵)との間に広い隙間S1が生じている場合には、これらの白鍵4、7(例えばE、Fの各白鍵)に最も近いねじ部材14の締め付け力を調節する。 Also, as shown in FIG. 12, among the white keys 4 and 7 of the first and second white key units 1 and 2, some of the white keys 7 (for example, E's) in the second white key unit 2 The white key) sways to the left in the arrangement direction of the white key 7, and there is a wide gap S1 between a part of the white keys 4 (for example, F white key) in the first white key unit 1 adjacent thereto. If it occurs, the tightening force of the screw member 14 closest to the white keys 4 and 7 (for example, E and F white keys) is adjusted.

すなわち、このねじ部材14の締め付け力を調整すると、図13に示すように、その締め付け力に応じて第1の白鍵共通支持部5における上側傾斜部16と第2の白鍵共通支持部8における下側傾斜部17とが相対的に滑り、図14に示すように、第1、第2の各白鍵共通支持部5、8の一部が変形する。このときには、図13に示すように、最上部に位置する第1の白鍵共通支持部5が変位しないように冶具19で押え、この状態でねじ部材14の締め付ける。 In other words, when the tightening force of the screw member 14 is adjusted, as shown in FIG. 13, the upper inclined portion 16 and the second white key common support portion 8 in the first white key common support portion 5 according to the tightening force. As shown in FIG. 14, a part of the first and second white key common support portions 5 and 8 is deformed. At this time, as shown in FIG. 13, the jig 19 is pressed so as not to displace the first white key common support portion 5 positioned at the top, and the screw member 14 is tightened in this state.

すると、図13および図14に示すように、ねじ部材14の締め付け力によって変形調整部15が、白鍵7(例えばEの白鍵)の後方(図13では右側)に向けて変位するので、第2の白鍵共通支持部8の一部が白鍵7(例えばEの白鍵)の後方(図14では上側)に向けて変形する。これに伴って一部の白鍵7(例えばEの白鍵)は、その配列方向における右側に横振れするように変位する。 Then, as shown in FIGS. 13 and 14, the deformation adjusting portion 15 is displaced toward the rear side (right side in FIG. 13) of the white key 7 (for example, the white key of E) by the tightening force of the screw member 14. A part of the second white key common support portion 8 is deformed toward the rear (upper side in FIG. 14) of the white key 7 (for example, the white key of E). Along with this, some white keys 7 (for example, E white keys) are displaced so as to sway to the right in the arrangement direction.

これにより、第1、第2の各白鍵ユニット1、2の各白鍵4、7のうち、第2の白鍵ユニット2における一部の白鍵7(例えばEの白鍵)が白鍵7の配列方向における右側に横振れしていても、この一部の白鍵7(例えばEの白鍵)の位置ずれが修正される。このため、第2の白鍵ユニット2における一部の白鍵7(例えばEの白鍵)と、これに隣接する第1の白鍵ユニットにおける一部の白鍵4(例えばFの白鍵)との間の隙間S1が広くても、図1に示すように、他の白鍵4、7間の隙間Sと同じ隙間Sに修正することができるので、全ての白鍵4、7間の隙間Sを均一にすることができる。 As a result, among the white keys 4 and 7 of the first and second white key units 1 and 2, a part of the white keys 7 (for example, E white key) in the second white key unit 2 are white keys. Even if the white key 7 sways to the right in the arrangement direction, the positional deviation of this part of the white keys 7 (for example, the E white key) is corrected. For this reason, a part of the white keys 7 in the second white key unit 2 (for example, the white key of E) and a part of the white keys 4 in the first white key unit adjacent thereto (for example, the white key of F) 1 can be corrected to the same gap S as the gap S between the other white keys 4 and 7, as shown in FIG. The gap S can be made uniform.

このように、この鍵盤構造によれば、第1、第2の各白鍵ユニット1、2および黒鍵ユニット3のうち、第1の白鍵ユニット1における複数の白鍵4の各間に、第2の白鍵ユニット2の各白鍵7を配置させて、各白鍵共通支持部5、8を重ねて合わせて相互に固定するときに、その固定力に応じて変形調整部15が白鍵共通支持部5、8の一部を白鍵4、7の前後方向に確実に変形させることができ、この白鍵共通支持部5、8の変形に伴って白鍵4、7の横振れを修正することができる。このため、互いに隣接する白鍵4、7同士の隙間Sを簡単に且つ正確に修正することができるので、多数の白鍵4、7の各隙間Sを均一にすることができる。 As described above, according to this keyboard structure, among the first and second white key units 1 and 2 and the black key unit 3, between the plurality of white keys 4 in the first white key unit 1, When each white key 7 of the second white key unit 2 is arranged and the respective white key common support portions 5 and 8 are overlapped and fixed to each other, the deformation adjusting portion 15 is whitened according to the fixing force. A part of the key common support portions 5 and 8 can be reliably deformed in the front-rear direction of the white keys 4 and 7, and the white keys 4 and 7 run out in accordance with the deformation of the white key common support portions 5 and 8. Can be corrected. For this reason, since the gap S between the white keys 4 and 7 adjacent to each other can be easily and accurately corrected, the gaps S of the many white keys 4 and 7 can be made uniform.

この場合、第1、第2の各白鍵共通支持部5、8は、互いに重なり合った状態で複数のねじ部材14によって相互に締め付けられて取り付けられ、複数の変形調整部15は、複数のねじ部材14の各締め付け力に応じてそれぞれ第1、第2の各白鍵共通支持部5、8の一部を白鍵4、7の前後方向に変形させるので、ねじ部材14の締め付け力を調整することにより、互いに隣接する白鍵4、7の隙間Sを簡単に且つ正確に修正することができる。 In this case, the first and second white key common support portions 5 and 8 are attached by being fastened to each other by a plurality of screw members 14 in a state of being overlapped with each other, and the plurality of deformation adjusting portions 15 are formed by a plurality of screw members. Since the parts of the first and second white key common support portions 5 and 8 are deformed in the front-rear direction of the white keys 4 and 7 according to the tightening force of the member 14, the tightening force of the screw member 14 is adjusted. By doing so, the gap S between the white keys 4 and 7 adjacent to each other can be corrected easily and accurately.

すなわち、変形調整部15は、第1、第2の各白鍵共通支持部5、8が重なり合って対面する対向面のうち、第1の白鍵共通支持部5の対向面である下面に白鍵4、7の長手方向に沿って傾斜して設けられた上側傾斜部16と、第2の白鍵共通支持部8の対向面である上面に白鍵4、7の長手方向に沿って傾斜して設けられた下側傾斜部17とを備えているので、ねじ部材14の締め付け力に応じて上側傾斜部16と下側傾斜部17とを、その両者の傾斜面に沿って相対的に滑らせることができる。 That is, the deformation adjusting unit 15 has a white surface on the lower surface which is the facing surface of the first white key common support portion 5 among the facing surfaces where the first and second white key common support portions 5 and 8 are overlapped and face each other. Inclined along the longitudinal direction of the white keys 4, 7 on the upper surface 16 which is provided to be inclined along the longitudinal direction of the keys 4, 7 and the upper surface which is the opposite surface of the second white key common support portion 8 Since the lower inclined portion 17 is provided, the upper inclined portion 16 and the lower inclined portion 17 are relatively moved along the inclined surfaces of both according to the tightening force of the screw member 14. Can slide.

このため、ねじ部材14の締め付け力に応じて変形調整部15を変位させて、第1、第2の各白鍵共通支持部5、8の一部を白鍵4、7の前後方向に確実に変形させることができ、これに伴って各白鍵4、7の配列方向における横振れを修正することができる。これにより、互いに隣接する白鍵4、7同士の隙間Sを簡単に且つ正確に修正することができるので、多数の白鍵4、7の各隙間Sを均一にすることができる。 For this reason, the deformation adjusting portion 15 is displaced in accordance with the tightening force of the screw member 14, so that a part of the first and second white key common support portions 5, 8 is reliably secured in the front-rear direction of the white keys 4, 7. Accordingly, the lateral shake in the arrangement direction of the white keys 4 and 7 can be corrected. Thereby, since the gap S between the white keys 4 and 7 adjacent to each other can be easily and accurately corrected, the gaps S of the many white keys 4 and 7 can be made uniform.

(実施形態2)
次に、図15〜図20を参照して、この発明を適用した鍵盤構造の実施形態2について説明する。なお、図1〜図14に示された実施形態1と同一部分には同一符号を付して説明する。
この鍵盤構造は、図16に示すように、第1の白鍵共通支持部5に変形調整部20を設けた構成であり、これ以外は実施形態1とほぼ同じ構成になっている。
(Embodiment 2)
Next, a second embodiment of a keyboard structure to which the present invention is applied will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected and demonstrated to the same part as Embodiment 1 shown by FIGS.
As shown in FIG. 16, this keyboard structure has a configuration in which a deformation adjusting unit 20 is provided in the first white key common support unit 5, and the other configuration is substantially the same as that of the first embodiment.

この変形調整部20は、図16に示すように、第1、第2の各白鍵共通支持部5、8が重なり合って対向する対向面のうち、上側に位置する第1の白鍵共通支持部5の対向面(図16では下面)に設けられた傾斜部であり、第1の白鍵共通支持部5が複数のねじ部材14によって固定される複数箇所に対応して設けられている。 As shown in FIG. 16, the deformation adjusting unit 20 includes a first white key common support located on the upper side of the opposing surfaces where the first and second white key common support portions 5 and 8 overlap and face each other. It is an inclined portion provided on the opposing surface (the lower surface in FIG. 16) of the portion 5, and the first white key common support portion 5 is provided corresponding to a plurality of locations fixed by the plurality of screw members 14.

この場合、変形調整部20は、図16に示すように、白鍵4の長手方向に対して直交する方向、つまり第1の白鍵共通支持部5の長手方向において一方側(図16では左側)が高く、他方側(図16では右側)が次第に低くなるように、第1の白鍵共通支持部5の長手方向に沿って傾斜する傾斜部に形成されている。この変形調整部20に対応する第1、第2の各白鍵共通支持部5、8および黒鍵共通支持部11の複数箇所にも、ねじ部材14が挿入する取付孔18が上下に対応して設けられている。 In this case, as shown in FIG. 16, the deformation adjustment unit 20 is arranged on one side in the direction orthogonal to the longitudinal direction of the white key 4, that is, in the longitudinal direction of the first white key common support unit 5 (left side in FIG. 16). ) Is high, and the other side (the right side in FIG. 16) is gradually lowered. The first white key common support portion 5 is formed in an inclined portion that is inclined along the longitudinal direction. The mounting holes 18 into which the screw members 14 are inserted also correspond to the top and bottom of the first and second white key common support portions 5 and 8 and the black key common support portion 11 corresponding to the deformation adjusting portion 20. Is provided.

これにより、変形調整部20は、図16および図19に示すように、第1、第2の各白鍵共通支持部5、8がねじ部材14によって締め付けられると、ねじ部材14の締め付け力に応じて第1の白鍵共通支持部5における変形調整部20が押し下げられるように変形し、その傾斜状態が変化することにより、第1の白鍵共通支持部5の一部を変形させて、白鍵7を捻じる方向に変位させるように構成されている。 Thereby, as shown in FIG. 16 and FIG. 19, when the first and second white key common support portions 5 and 8 are tightened by the screw member 14, the deformation adjusting unit 20 increases the tightening force of the screw member 14. Accordingly, the deformation adjustment unit 20 in the first white key common support unit 5 is deformed so as to be pushed down, and the inclined state changes, so that a part of the first white key common support unit 5 is deformed, The white key 7 is configured to be displaced in the twisting direction.

例えば、図17および図18に示すように、第1の鍵ユニット1における複数の白鍵4のうち、一部の白鍵4(例えばFの白鍵)が白鍵4の配列方向において右回り(時計回り)に捻じれ、これに隣接する第2の白鍵ユニット2における一部の白鍵7(例えばEの白鍵)との間に広い隙間S1が生じている場合には、これらの白鍵4、7(例えばF、Eの各白鍵)に最も近いねじ部材14の締め付け力を調節する。 For example, as shown in FIGS. 17 and 18, among the plurality of white keys 4 in the first key unit 1, some white keys 4 (for example, F white keys) are clockwise in the arrangement direction of the white keys 4. When a wide gap S1 is generated between the second white key unit 2 adjacent to the second white key unit 2 and the white key 7 (for example, E white key) adjacent thereto, The tightening force of the screw member 14 closest to the white keys 4 and 7 (for example, F and E white keys) is adjusted.

すなわち、このねじ部材14の締め付け力を調整すると、図19に示すように、その締め付け力に応じて第1の白鍵共通支持部5における変形調整部20である傾斜部が押し下げられるように変形し、その傾斜状態が変化することにより、第1の白鍵共通支持部5の一部を変形させ、これに伴って一部の白鍵4(例えばFの白鍵)が、図20に示すように、左回り(反時計回り)に捻じれる。 That is, when the tightening force of the screw member 14 is adjusted, as shown in FIG. 19, the inclined portion which is the deformation adjusting portion 20 in the first white key common support portion 5 is pushed down according to the tightening force. Then, by changing the inclination state, a part of the first white key common support portion 5 is deformed, and a part of the white keys 4 (for example, the F white key) are shown in FIG. Twisted counterclockwise (counterclockwise).

これにより、第1の白鍵ユニット1における複数の白鍵4のうち、図18に示すように、一部の白鍵4(例えばFの白鍵)が右回り(時計回り)に捻じれていても、この捻じれた一部の白鍵4(例えばFの白鍵)が、図20に示すように、左回り(反時計回り)に捻じれて修正される。 Thereby, among the plurality of white keys 4 in the first white key unit 1, as shown in FIG. 18, some of the white keys 4 (for example, the F white key) are twisted clockwise (clockwise). However, as shown in FIG. 20, the twisted white key 4 (for example, F white key) is twisted counterclockwise (counterclockwise) and corrected.

このため、図17に示すように、第1の白鍵ユニット1における一部の白鍵4(例えばFの白鍵)と、これに隣接する第2の白鍵ユニット2における一部の白鍵7(例えばEの白鍵)との間の隙間S1が広くても、図15に示すように、他の白鍵4、7間の隙間Sと同じ隙間Sに修正することができるので、全ての白鍵4、7間の隙間Sを均一にすることができる。 For this reason, as shown in FIG. 17, a part of the white keys 4 in the first white key unit 1 (for example, the white key of F) and a part of the white keys in the second white key unit 2 adjacent thereto. 7 (for example, the white key of E) can be corrected to the same gap S as the gap S between the other white keys 4 and 7, as shown in FIG. The gap S between the white keys 4 and 7 can be made uniform.

このような鍵盤構造においても、実施形態1と同様、第1、第2の各白鍵ユニット1、2および黒鍵ユニット3のうち、第1の白鍵ユニット1における複数の白鍵4の各間に、第2の白鍵ユニット2の各白鍵7を配置させて、各白鍵共通支持部5、8を重ねて合わせて相互に固定するときに、その固定力に応じて変形調整部20が押し下げられるように変形し、第1の白鍵共通支持部5の一部を確実に変形させることができ、これに伴って白鍵4を捻じる方向に変位させることができる。このため、互いに隣接する白鍵4、7同士の隙間Sを簡単に且つ正確に修正することができるので、多数の白鍵4、7の各隙間Sを均一にすることができる。 Also in such a keyboard structure, each of the plurality of white keys 4 in the first white key unit 1 out of the first and second white key units 1 and 2 and the black key unit 3 as in the first embodiment. When the white keys 7 of the second white key unit 2 are arranged between them, and the white key common support portions 5 and 8 are overlapped and fixed to each other, the deformation adjusting portion according to the fixing force. 20 can be deformed so as to be pushed down, and a part of the first white key common support portion 5 can be reliably deformed, and accordingly, the white key 4 can be displaced in the twisting direction. For this reason, since the gap S between the white keys 4 and 7 adjacent to each other can be easily and accurately corrected, the gaps S of the many white keys 4 and 7 can be made uniform.

この場合、第1、第2の各白鍵共通支持部5、8は、互いに重なり合った状態で複数のねじ部材14によって相互に締め付けられて取り付けられ、複数の変形調整部20は、複数のねじ部材14の各締め付け力に応じてそれぞれ押し下げられるように変形して、第1の白鍵共通支持部5の一部を確実に変形させるので、ねじ部材14の締め付け力を調整することにより、互いに隣接する白鍵4、7の隙間Sを簡単に且つ正確に修正することができる。 In this case, the first and second white key common support portions 5 and 8 are attached by being fastened to each other by a plurality of screw members 14 while being overlapped with each other, and the plurality of deformation adjusting portions 20 are provided with a plurality of screw members. Since it deform | transforms so that it may each be pressed down according to each clamping force of the member 14, and deform | transforms a part of the 1st white key common support part 5 reliably, by adjusting the clamping force of the screw member 14, mutually The gap S between the adjacent white keys 4 and 7 can be easily and accurately corrected.

すなわち、この変形調整部20は、第1、第2の各白鍵共通支持部5、8が重なり合って対面する対向面のうち、第1の白鍵共通支持部5の対向面である下面に、白鍵4の長手方向に対して直交する方向、つまり第1の白鍵共通支持部5の長手方向に沿って傾斜して設けられた傾斜部であるから、ねじ部材14の締め付け力に応じて押し下げられるように変形し、第1の白鍵共通支持部5の一部を確実に変形させることができる。このため、白鍵4を捻じるように変位させることができるので、互いに隣接する白鍵4、7同士の隙間Sを簡単に且つ正確に修正することができ、これにより多数の白鍵4、7の各隙間Sを均一にすることができる。 That is, the deformation adjusting unit 20 is formed on the lower surface which is the facing surface of the first white key common support portion 5 among the facing surfaces where the first and second white key common support portions 5 and 8 are overlapped and face each other. Since the inclined portion is inclined along the longitudinal direction of the white key 4, that is, the longitudinal direction of the first white key common support portion 5, it corresponds to the tightening force of the screw member 14. The first white key common support portion 5 can be reliably deformed by being deformed so as to be pushed down. For this reason, since the white key 4 can be displaced so as to be twisted, the gap S between the adjacent white keys 4 and 7 can be easily and accurately corrected. 7 can be made uniform.

(実施形態3)
次に、図21〜図26を参照して、この発明を適用した鍵盤構造の実施形態3について説明する。この場合にも、図1〜図14に示された実施形態1と同一部分に同一符号を付して説明する。
この鍵盤構造は、図21および図22に示すように、第1の白鍵共通支持部5の上に第2の白鍵共通
支持部8を重ね合わせて配置し、この第2の白鍵共通支持部8に変形調整部25を設けた構成であり、これ以外は実施形態1とほぼ同じ構成になっている。
(Embodiment 3)
Next, a third embodiment of a keyboard structure to which the present invention is applied will be described with reference to FIGS. Also in this case, the same portions as those in the first embodiment shown in FIGS.
As shown in FIGS. 21 and 22, the keyboard structure is configured such that the second white key common support portion 8 is placed on the first white key common support portion 5 so as to overlap the second white key common support portion. This is a configuration in which the deformation adjusting unit 25 is provided in the support unit 8, and the other configuration is substantially the same as in the first embodiment.

この変形調整部25は、図22に示すように、第1、第2の各白鍵共通支持部5、8が重なり合って対向する対向面のうち、上部側に位置する第2の白鍵共通支持部8の対向面(図22では下面)に設けられた傾斜部であり、第2の白鍵共通支持部8が複数のねじ部材14によって固定される複数箇所に対応して設けられている。 As shown in FIG. 22, the deformation adjusting unit 25 has a second white key common located on the upper side of the opposing surfaces where the first and second white key common support portions 5 and 8 overlap and face each other. It is an inclined portion provided on the opposing surface (lower surface in FIG. 22) of the support portion 8, and the second white key common support portion 8 is provided corresponding to a plurality of locations fixed by the plurality of screw members 14. .

この場合、変形調整部25は、図22に示すように、白鍵7の長手方向に対して直交する方向、つまり第2の白鍵共通支持部8の長手方向において一方側(図22では左側)が高く、他方側(図22では右側)が次第に低くなるように、第2の白鍵共通支持部8の長手方向に沿って傾斜する傾斜部に形成されている。この変形調整部25に対応する第1、第2の各白鍵共通支持部5、8および黒鍵共通支持部11の複数箇所にも、ねじ部材14が挿入する取付孔18が上下に対応して設けられている。 In this case, as shown in FIG. 22, the deformation adjusting unit 25 is arranged on one side in the direction orthogonal to the longitudinal direction of the white key 7, that is, in the longitudinal direction of the second white key common support unit 8 (on the left side in FIG. ) Is high, and the other side (the right side in FIG. 22) is gradually lowered. The second white key common support portion 8 is formed in an inclined portion that is inclined along the longitudinal direction. The mounting holes 18 into which the screw members 14 are inserted also correspond to the top and bottom at a plurality of locations of the first and second white key common support portions 5 and 8 and the black key common support portion 11 corresponding to the deformation adjusting portion 25. Is provided.

これにより、変形調整部25は、図22および図25に示すように、第1、第2の各白鍵共通支持部5、8がねじ部材14によって締め付けられると、ねじ部材14の締め付け力に応じて第2の白鍵共通支持部8における変形調整部25が押し下げられるように変形し、その傾斜状態が変化することにより、第2の白鍵共通支持部8の一部を変形させて、白鍵7を捻じる方向に変位させるように構成されている。 Thereby, as shown in FIG. 22 and FIG. 25, when the first and second white key common support portions 5 and 8 are tightened by the screw member 14, the deformation adjusting unit 25 increases the tightening force of the screw member 14. Accordingly, the deformation adjustment unit 25 in the second white key common support portion 8 is deformed so as to be pushed down, and the inclined state changes, so that a part of the second white key common support portion 8 is deformed, The white key 7 is configured to be displaced in the twisting direction.

例えば、図23および図24に示すように、第2の鍵ユニット2における複数の白鍵7のうち、一部の白鍵7(例えばEの白鍵)が白鍵7の配列方向において左回り(反時計回り)に捻じれ、これに隣接する第1の白鍵ユニット1における一部の白鍵4(例えばFの白鍵)との間に広い隙間S1が生じている場合には、これらの白鍵4、7(例えばF、Eの各白鍵)に最も近いねじ部材14の締め付け力を調節する。 For example, as shown in FIG. 23 and FIG. 24, among the white keys 7 in the second key unit 2, some white keys 7 (for example, E white keys) are counterclockwise in the arrangement direction of the white keys 7. If a wide gap S1 is generated between the first white key unit 1 adjacent to the first white key unit 1 and a part of the white keys 4 (for example, the white key of F) twisted in a counterclockwise direction, The tightening force of the screw member 14 closest to the white keys 4 and 7 (for example, F and E white keys) is adjusted.

すなわち、このねじ部材14の締め付け力を調整すると、図25に示すように、その締め付け力に応じて第2の白鍵共通支持部8における変形調整部25である傾斜部が押し下げられるように変形し、その傾斜状態が変化することにより、第2の白鍵共通支持部8の一部を確実に変形させ、これに伴って一部の白鍵7(例えばEの白鍵)が、図26に示すように、右回り(時計回り)に捻じれる。 That is, when the tightening force of the screw member 14 is adjusted, as shown in FIG. 25, the inclined portion which is the deformation adjusting portion 25 in the second white key common support portion 8 is pushed down according to the tightening force. Then, by changing the tilted state, a part of the second white key common support portion 8 is surely deformed, and accordingly, a part of the white keys 7 (for example, the white key of E) is changed as shown in FIG. As shown in Fig. 2, it is twisted clockwise (clockwise).

これにより、第2の白鍵ユニット2における複数の白鍵7のうち、一部の白鍵7(例えばEの白鍵)が左回り(反時計回り)に捻じれていても、この捻じれた一部の白鍵7(例えばEの白鍵)が、図26に示すように、右回り(反時計回り)に捻じれて修正される。このため、図23に示すように、第2の白鍵ユニット2における一部の白鍵7(例えばEの白鍵)と、これに隣接する第1の白鍵ユニット1における一部の白鍵4(例えばFの白鍵)との間の隙間S1が広くても、図21に示すように、他の白鍵4、7間の隙間Sと同じ隙間Sに修正することができるので、全ての白鍵4、7間の隙間Sを均一にすることができる。 Thereby, even if some white keys 7 (for example, E white key) are twisted counterclockwise (counterclockwise) among the plurality of white keys 7 in the second white key unit 2. Some white keys 7 (for example, E white key) are twisted clockwise (counterclockwise) and corrected as shown in FIG. Therefore, as shown in FIG. 23, a part of the white keys 7 in the second white key unit 2 (for example, the white key of E) and a part of the white keys in the first white key unit 1 adjacent thereto. 4 (for example, the white key of F) can be corrected to the same gap S as the gap S between the other white keys 4 and 7, as shown in FIG. The gap S between the white keys 4 and 7 can be made uniform.

このような鍵盤構造においても、実施形態1と同様、第1、第2の各白鍵ユニット1、2および黒鍵ユニット3のうち、第1の白鍵ユニット1における複数の白鍵4の各間に、第2の白鍵ユニット2の各白鍵7を配置させて、各白鍵共通支持部5、8を重ねて合わせて相互に固定するときに、その固定力に応じて変形調整部25が押し下げられるように変形して、第2の白鍵共通支持部8の一部を確実に変形させることができ、これに伴って白鍵7を捻じる方向に変位させることができる。このため、互いに隣接する白鍵4、7同士の隙間Sを簡単に且つ正確に修正することができるので、多数の白鍵4、7の各隙間Sを均一にすることができる。 Also in such a keyboard structure, each of the plurality of white keys 4 in the first white key unit 1 out of the first and second white key units 1 and 2 and the black key unit 3 as in the first embodiment. When the white keys 7 of the second white key unit 2 are arranged between them, and the white key common support portions 5 and 8 are overlapped and fixed to each other, the deformation adjusting portion according to the fixing force. Thus, the second white key common support portion 8 can be deformed to be surely deformed, and accordingly, the white key 7 can be displaced in the twisting direction. For this reason, since the gap S between the white keys 4 and 7 adjacent to each other can be easily and accurately corrected, the gaps S of the many white keys 4 and 7 can be made uniform.

この場合、第1、第2の各白鍵共通支持部5、8は、互いに重なり合った状態で複数のねじ部材14によって相互に締め付けられて取り付けられ、複数の変形調整部25は、複数のねじ部材14の各締め付け力に応じてそれぞれ押し下げられるように変形して、第2の白鍵共通支持部8の一部を確実に変形させるので、ねじ部材14の締め付け力を調整することにより、互いに隣接する白鍵4、7の隙間Sを簡単に且つ正確に修正することができる。 In this case, the first and second white key common support portions 5 and 8 are attached by being fastened to each other by a plurality of screw members 14 in a state of being overlapped with each other, and the plurality of deformation adjusting portions 25 are formed by a plurality of screw members. Since each of the second white key common support portions 8 is deformed so as to be pushed down according to each tightening force of the member 14, the second white key common support portion 8 is reliably deformed. The gap S between the adjacent white keys 4 and 7 can be easily and accurately corrected.

すなわち、変形調整部25は、第1、第2の各白鍵共通支持部5、8が重なり合って対面する対向面のうち、最上部に位置する第2の白鍵共通支持部8の対向面である下面に、白鍵7の長手方向に対して直交する方向、つまり第2の白鍵共通支持部8の長手方向に沿って傾斜して設けられた傾斜部であるから、ねじ部材14の締め付け力に応じて押し下げられるように変形して、第2の白鍵共通支持部8の一部を確実に変形させることができる。このため、白鍵7を捻じるように変位させることができるので、互いに隣接する白鍵4、7同士の隙間Sを簡単に且つ正確に修正することができ、これにより多数の白鍵4、7の各隙間Sを均一にすることができる。 That is, the deformation adjusting unit 25 is a facing surface of the second white key common support portion 8 positioned at the uppermost portion of the facing surfaces where the first and second white key common support portions 5 and 8 overlap and face each other. Since the inclined surface is inclined along the direction perpendicular to the longitudinal direction of the white key 7, that is, the longitudinal direction of the second white key common support portion 8, the lower surface of the screw member 14 A part of the second white key common support portion 8 can be reliably deformed by being deformed so as to be pushed down according to the tightening force. For this reason, since the white key 7 can be displaced so as to be twisted, the gap S between the white keys 4 and 7 adjacent to each other can be easily and accurately corrected, whereby a large number of white keys 4, 7 can be made uniform.

なお、前記実施形態2、3では、第1、第2の各白鍵共通支持部5、8のいずれか一方のみに変形調整部20、25を設けた場合について述べたが、これに限らず、第1、第2の各白鍵共通支持部5、8の両方に変形調整部20、25をそれぞれ設けた構成でも良い。このように構成すれば、1本のねじ部材14の締め付け力に応じて第1、第2の各白鍵共通支持部5、8の両方を同時に変形させて、白鍵4、7の隙間を修正することができる。 In the second and third embodiments, the case where the deformation adjustment units 20 and 25 are provided only in one of the first and second white key common support portions 5 and 8 has been described. The first and second white key common support portions 5 and 8 may be provided with deformation adjusting portions 20 and 25, respectively. If comprised in this way, according to the fastening force of the one screw member 14, both the 1st, 2nd white key common support parts 5 and 8 will be changed simultaneously, and the clearance gap between the white keys 4 and 7 will be carried out. Can be corrected.

また、前記実施形態1〜3では、変形調整部15、20、25を第1、第2の各白鍵共通支持部5、8が複数のねじ部材14によって固定される複数箇所に設けた場合について述べたが、これに限らず、変形調整部は、複数のねじ部材14によって固定される複数箇所の近傍に設けられた構成であっても良い。このように構成しても、実施形態1〜3と同様の作用効果がある。 In the first to third embodiments, the deformation adjusting portions 15, 20, 25 are provided at a plurality of locations where the first and second white key common support portions 5, 8 are fixed by the plurality of screw members 14. However, the present invention is not limited to this, and the deformation adjusting unit may be provided in the vicinity of a plurality of locations fixed by the plurality of screw members 14. Even if comprised in this way, there exists an effect similar to Embodiment 1-3.
