Definitions
- the present invention relates to a damper device for an upright piano.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2001-343969
- the damper itself is composed of a damper lever, a damper wire provided at one end thereof, and a damper provided at the tip of the damper wire.
- the damper is pivotally supported at the center of the damper lever by a damper flange provided on a center rail provided between brackets installed on a fixed part such as a piano shelf.
- the damper is provided with a damper spring between the damper lever and the damper flange, the damper lever is always pressed, and the damper provided at the tip is urged in the direction of pressing the string.
- the whippen is pivotally supported in the whippen frenzy, the whippen is rotated through the capstan 4 by keystroke of the keyboard, and the bat is pushed up by the jack supported by the whippen and pivoted on the bat. Turn the supported hammer and hit the string.
- the damper spoon provided at the rear end thereof presses the damper lever against the urging force of the damper spring, and the damper is separated from the string with which the damper is in press contact. Therefore, the strings are released and a piano sound is generated when the strings are struck.
- the strings used for pianos are usually composed of one string for bass, two strings for low and medium sounds, and three strings for medium and high sounds. Yes.
- the portion that hits the string at that time becomes a groove, the groove portion is hardened, and the other peak portion is soft.
- the damper of the upright piano has a structure in which the groove hits the single string, but in the case of two strings or three strings, it enters between the strings and produces a silencing effect.
- a soft pedal is provided, and by using the soft pedal, the configuration of the action is configured to slide in the horizontal direction, the hammer moves in the horizontal direction, and the felt mountain portion of the hammer head The sound hits the string and becomes soft.
- the damper is formed integrally with the action, so that neither the action nor the damper can be slid sideways. Further, in the upright piano, in order to emit a weak sound, the position of the hammer is changed, the hammer is moved forward, and the rotation distance is shortened to produce a soft tone (see, for example, Patent Document 3). ).
- the weak point in this conventional upright piano is that the hammer is rotated by pressing the damper lever by pressing the damper lever with the spoon on the whippen when the key is pressed. It is in the point formed integrally with the structure which pushes a lever.
- the present invention does not require various complicated mechanisms in the upright piano, and by providing a mechanism that is easy to use, the upright piano can be configured separately from the action and the damper device.
- the damper device and the action can be configured separately, and therefore the action can be configured to move away from the damper device, and the portion hitting the string of the hammer can be moved in the same manner as the action movement of the grand piano.
- the purpose is to produce a soft sound.
- this damper device allows the damper to return to its old position under its own weight and hold down the strings without using the biasing force of the spring, so that it does not give the player a so-called springy feel.
- the purpose is to give the same playing feeling as a grand piano.
- an object of the present invention is to make the damper device independent from the operation of the whippen and the action mechanism in the upright piano, and to obtain the configuration thereof.
- the present invention proposes the following configuration.
- the damper head comes into contact with the string stretched in the vertical direction to stop the sound, and the damper lever that supports the damper head by rotating the key is rotated.
- a damper device for an upright piano in which a damper head is separated from a string, wherein the damper lever is pivotally supported by an immovable damper flange provided in front of the string and a protruding portion is provided at the rear end of the keyboard.
- a damper device for an upright piano characterized in that the upper portion of the projection is opposed to the lower portion of the damper lever.
- one end portion of the damper lever integrally connected with the damper head is pivotally supported by the pivot pin so as to be pivoted to the stationary damper flange provided in front of the string.
- a damper device for an upright piano which is disposed between the pivot pin and the string and urges the damper head against the string in the contact direction by the weight of the damper head and the damper lever.
- the damper wire having the damper head at the upper end is planted at the rear end portion of the damper lever, and the front end portion of the damper lever is turned to the stationary damper flange provided at the front of the string.
- Upright piano damper device characterized by being pivotally supported.
- the damper flange is supported by a Japanese suspension arm so as to move in the lateral direction, and the damper lever is supported directly on the rear end portion of the damper lever or the damper lever upright portion via the damper wire or
- the damper head is integrally provided without being interposed, and a protruding portion is provided at the rear end portion of the keyboard, and the protruding portion is opposed to the rear end portion of the damper lever or the lower end of the damper lever upright portion.
- Upright piano damper device according to claim 1.
- the damper lever having the damper head integrally connected to the upper end is pivotally supported by the pivot pin on the stationary damper flange provided in front of the string at the center thereof.
- a damper device for an upright piano wherein the damper head and the damper lever are supported and urged in the contact direction against the string by the weight of the damper head.
- the damper wire or the damper lever for supporting the damper head is rotated on the damper flange provided on the damper rail provided on the fixing portion such as the shelf board or the bracket of the main body of the upright piano. Because it is pivotally supported, and a protruding part is provided at the rear end of the keyboard, and the protruding part is opposed to the lower part of the damper lever, the operation of the damper head is completely different from the operation of the hammer,
- the damper device could have an independent configuration that had nothing to do with the whippen in action to activate the hammer.
- the damper device is installed at a fixed position, while the action can be configured to be movable in the left-right direction on the cage. If this configuration can be adopted, the action for producing a soft sound can be moved by adopting the pedal mechanism as in the case of the grand piano.
- the weak mechanism of the conventional upright piano has become a complicated device, such as limiting or releasing the rotation distance of the hammer, but this can be made unnecessary.
- the soft mechanism of the grand piano can move the action, the hammer moves a little due to the movement of the action, the part of the hammer head that hits the string hits the soft mountain part and makes a soft sound I can do it.
- the same soft sound component mechanism can be adopted since the damper device and the damper device are separately configured in the same manner as this.
- the front end of the damper lever is pivotally supported by a damper flange fixed to a bracket or the like, and the weight of the damper head, the damper wire, and the damper lever is determined after the damper lever. It rests on the end, that is, the part near the string. For this reason, the damper head is brought into contact with the string S by a pivoting moment about the pivot pin toward the rear side, that is, the string side.
- the front end of the damper lever is pivotally supported by the pivot pin so that the weight of the damper head, the damper wire, and the damper lever is close to the rear end portion of the damper lever, that is, the string. It depends on the part. Therefore, the operation is the same as that according to the invention of claim 2. However, due to the simplicity of the configuration, it is convenient in production and use. Also, the adjustment of the weight is simple, and the weight can be easily selected by selecting, for example, metal, hardwood, plastic, etc. according to the material of the damper lever.
- the damper lever pivotally supports two arms on a damper flange provided on a non-moving portion such as a rail at an appropriate interval, and the damper lever is provided at the lower end of the arm. Each is pivotally supported. For this reason, the damper lever is movable in the lateral direction.
- the damper lever is pivotally supported at the lower end of the arm, and the damper head is integrally connected to the rear end of the damper lever via a damper wire. The upper part provided at the rear end of the keyboard is opposed.
- FIG. 4 the damper lever pivotally supports two arms on a damper flange provided on a non-moving portion such as a rail at an appropriate interval, and the damper lever is provided at the lower end of the arm. Each is pivotally supported. For this reason, the damper lever is movable in the lateral direction.
- the damper lever is pivotally supported at the lower end of the arm, and the damper head is integrally connected to the rear end of the damper lever via a damper wire
- the lower end of the arm is pivotally supported by the damper flange
- the damper lever is pivotally supported by the upper end of the arm so that the damper lever can be moved in the lateral direction.
- the lower center portion of the damper lever is pivotally supported by a damper flange fixed to a bracket or the like, and most of the damper head and damper lever are pivot pins. Since the damper head and damper lever are located closer to the string side than the pivot pin, the weight of the damper head and damper lever should be adjusted so that the damper head rotates to the string side. A turning moment is applied to the damper lever at the center, and the damper head is brought into contact with the string S.
- the damper lever rotates so that the protruding upper part pushes the lower end of the damper lever, and the damper head separates from the string and allows the generation of sound.
- the damper head rotates the damper head and the damper lever itself around the pivot pin by weight, and comes into contact with the string to prevent generation of sound. Therefore, in the damper device, it is not necessary to provide a spring or a weight, and the device has a simple configuration, and it is easy to manufacture and use is also easy without the need for adjusting the spring or the weight.

Description
本発明はアップライトピアノのダンパー装置に関する。 The present invention relates to a damper device for an upright piano.
従来のアップライトピアノのダンパー装置は、例えば特開2001-343969(特許文献1)に示される。 A conventional upright piano damper device is disclosed in, for example, Japanese Patent Application Laid-Open No. 2001-343969 (Patent Document 1).
ダンパー自体の構成は、ダンパーレバー及びその一端に設けられたダンパーワイヤー、該ダンパーワイヤー先端に設けられたダンパーより成る。
該ダンパーは、ダンパーレバーの中央を、ピアノの棚板等の固定部に設置したブラケット間に渡されたセンターレールに設けたダンパーフレンジに回動自在に枢支してある。
該ダンパーは、ダンパーレバーとダンパーフレンジ間にダンパースプリングが設けられ、ダンパーレバーは常時押圧され、その先端に設けたダンパーは弦を押さえる方向に付勢されている。
The damper itself is composed of a damper lever, a damper wire provided at one end thereof, and a damper provided at the tip of the damper wire.
The damper is pivotally supported at the center of the damper lever by a damper flange provided on a center rail provided between brackets installed on a fixed part such as a piano shelf.
The damper is provided with a damper spring between the damper lever and the damper flange, the damper lever is always pressed, and the damper provided at the tip is urged in the direction of pressing the string.
一方、センターレールには、ウィッペンフレンジにウィッペンを回動自在に枢支し、鍵盤の打鍵によりキャプスタン4を介してウィッペンを回動させ、ウィッペンに支承したジャックによりバットを突上げバットに枢支したハンマーを回動させ打弦する。 On the other hand, on the center rail, the whippen is pivotally supported in the whippen frenzy, the whippen is rotated through the capstan 4 by keystroke of the keyboard, and the bat is pushed up by the jack supported by the whippen and pivoted on the bat. Turn the supported hammer and hit the string.
この打弦時に、ウィッペンの回動によりその後端に設けたダンパースプーンがダンパースプリングの付勢力に抗してダンパーレバーを押圧し、ダンパーが押圧接触していた弦から離間する。そこで弦が開放され打弦によりピアノ音が発生する。 When the string is struck, the damper spoon provided at the rear end thereof presses the damper lever against the urging force of the damper spring, and the damper is separated from the string with which the damper is in press contact. Therefore, the strings are released and a piano sound is generated when the strings are struck.
この構成は、押鍵によるダンパーレバーの回動の際に、ダンパースプリングのばね力が、スプーンなどを介し、押鍵に対する反力の一部として演奏者の指に伝達され、ばねっぽいタッチ感が生じる。この他アップライトピアノに於いて複数のばねがアクションに用いられているためばねっぽいタッチ感がグランドピアノよりも顕著である。それが好ましくないとして、ダンパーレバーとダンパーフレンジ間にばねを設けず、ダンパーレバー下端におもりを設けた構成が提案されている。このおもりは、自重によりダンパーヘッドを弦側に回動させる方向の支点回りのモーメントをダンパーヘッドの弦押圧方向へのおもりとなる(特許文献2参照。)。 In this configuration, when the damper lever is rotated by the key depression, the spring force of the damper spring is transmitted to the performer's finger as a part of the reaction force against the key depression via a spoon etc. Occurs. In addition, since a plurality of springs are used for the action in the upright piano, a springy touch feeling is more remarkable than that of the grand piano. As this is not preferable, a configuration in which a spring is not provided between the damper lever and the damper flange and a weight is provided at the lower end of the damper lever has been proposed. In this weight, a moment around a fulcrum in a direction in which the damper head is turned to the string side by its own weight becomes a weight in the string pressing direction of the damper head (see Patent Document 2).
又、アップライトピアノに於いて、使用されるピアノの弦は低音は一本張り、低中音は2本張り、中音と高音は3本張りのように構成されたものが通常使用されている。
このため、ハンマーの打面たるハンマーヘッドのフェルトは、弦に当時当たる部分が溝になり、該溝部が硬化し、他の山部が軟らかいことになる。
Also, in upright pianos, the strings used for pianos are usually composed of one string for bass, two strings for low and medium sounds, and three strings for medium and high sounds. Yes.
For this reason, in the felt of the hammer head which is the hammering surface, the portion that hits the string at that time becomes a groove, the groove portion is hardened, and the other peak portion is soft.
更に、アップライトピアノのダンパーは、一本弦に対して溝部が当たるが、2本弦、3本弦の場合、弦の間に入り込んで消音効果を出す構成である。 Furthermore, the damper of the upright piano has a structure in which the groove hits the single string, but in the case of two strings or three strings, it enters between the strings and produces a silencing effect.
グランドピアノに於いて、ソフトペダルが備えられ、該ソフトペダルの使用により、アクションの構成が横方向にスライドする構成となっており、ハンマーが横方向に移動し、ハンマーヘッドのフェルトの山の部分で弦に当たり音がソフトになる。 In the grand piano, a soft pedal is provided, and by using the soft pedal, the configuration of the action is configured to slide in the horizontal direction, the hammer moves in the horizontal direction, and the felt mountain portion of the hammer head The sound hits the string and becomes soft.
一方、アップライトピアノの従来方式では、ダンパーはアクションと一体的に形成しているので、アクションも又ダンパーも横にスライドさせることは出来ない。
又、アップライトピアノに於いて、弱音を出すために、ハンマーの位置を換えハンマーを前に出して、その回動距離を短くしてソフトの音色を出している(例えば、特許文献3参照。)。
On the other hand, in the conventional system of the upright piano, the damper is formed integrally with the action, so that neither the action nor the damper can be slid sideways.
Further, in the upright piano, in order to emit a weak sound, the position of the hammer is changed, the hammer is moved forward, and the rotation distance is shortened to produce a soft tone (see, for example, Patent Document 3). ).
しかし、弱音のための機構は複雑で装置の作成も使用も面倒である。この従来のアップライトピアノに於ける弱点は、打鍵によりウィッペンを介してその作動をウィッペン上のスプーンによりダンパーレバーを押し回動させることで、打鍵によりハンマーを回動させる構成とウィッペンを介してダンパーレバーを押す構成と一体的に形成した点にある。 However, the mechanism for weak sound is complicated, and it is troublesome to create and use the device. The weak point in this conventional upright piano is that the hammer is rotated by pressing the damper lever by pressing the damper lever with the spoon on the whippen when the key is pressed. It is in the point formed integrally with the structure which pushes a lever.

請求項4に記載の発明によれば、ダンパーフレンジに日本の吊り腕によりダンパーレバーを横方向移動する如く支承させると共に該ダンパーレバー後端部に直接又はダンパーレバー直立部にダンパーワイヤーを介して又は介さず一体的にダンパーヘッドを設ける一方、鍵盤後端部に突上部を儲け、該突上部をダンパーレバー後端部又はダンパーレバー直立部下端に対峙させたことを特徴とする請求項1又は2に記載のアップライトピアノのダンパー装置。 According to the invention described in claim 4, the damper flange is supported by a Japanese suspension arm so as to move in the lateral direction, and the damper lever is supported directly on the rear end portion of the damper lever or the damper lever upright portion via the damper wire or The damper head is integrally provided without being interposed, and a protruding portion is provided at the rear end portion of the keyboard, and the protruding portion is opposed to the rear end portion of the damper lever or the lower end of the damper lever upright portion. Upright piano damper device according to claim 1.
請求項5に記載の発明によれば、上端にダンパーヘッドを一体的に連結したダンパーレバーをその中央部にて前記弦の前方に設けた不動のダンパーフレンジに枢支ピンにより回動自在に枢支させると共にダンパーヘッド、ダンパーレバーの重量によりダンパーヘッドを弦に接触方向に付勢することを特徴とするアップライトピアノのダンパー装置。 According to the fifth aspect of the present invention, the damper lever having the damper head integrally connected to the upper end is pivotally supported by the pivot pin on the stationary damper flange provided in front of the string at the center thereof. A damper device for an upright piano, wherein the damper head and the damper lever are supported and urged in the contact direction against the string by the weight of the damper head.
上記請求項1に記載のダンパー装置によれば、アップライトピアノの本体の棚板或いはブラケット等の固定部に設けたダンパーレールに設けたダンパーフレンジにダンパーヘッドを支えるダンパーワイヤー或いはダンパーレバーを回動自在に枢支させてあること、又鍵盤後端部に突上部を設け、該突上部をダンパーレバー下部に対峙させてあることにより、ダンパーヘッドの作動はハンマーの動作とは全く別動作となり、ダンパー装置はハンマーを作動させるアクション就中ウィッペンとは全く関連のない独立の構成にすることが出来た。 According to the damper device of the first aspect, the damper wire or the damper lever for supporting the damper head is rotated on the damper flange provided on the damper rail provided on the fixing portion such as the shelf board or the bracket of the main body of the upright piano. Because it is pivotally supported, and a protruding part is provided at the rear end of the keyboard, and the protruding part is opposed to the lower part of the damper lever, the operation of the damper head is completely different from the operation of the hammer, The damper device could have an independent configuration that had nothing to do with the whippen in action to activate the hammer.
この為、ダンパー装置は固定位置に設置しておく、一方アクションは筬上で左右方向に移動可能に構成できる。
この構成の採用が可能であれば、グランドピアノと同様ペダル機構の採用によりソフト音を出すためのアクションの移動が可能になる。
For this reason, the damper device is installed at a fixed position, while the action can be configured to be movable in the left-right direction on the cage.
If this configuration can be adopted, the action for producing a soft sound can be moved by adopting the pedal mechanism as in the case of the grand piano.
従来のアップライトピアノの弱音機構は例えばハンマーの回動距離の制限又その解除等複雑な装置となったが、これを不要とすることが出来る。 The weak mechanism of the conventional upright piano has become a complicated device, such as limiting or releasing the rotation distance of the hammer, but this can be made unnecessary.
又、グランドピアノのソフト機構はアクションの移動が可能であるため、アクションの移動によりハンマーが少し動き、ハンマーヘッドのフェルト部の動きで弦を打つ部分がソフトな山の部分に当たり、ソフト音を出すことが出来る。
本願発明の構成も、これと同様にダンパー装置をハンマーによる打弦を行なうアクションとダンパー装置を別箇に構成したので同じソフト音の構成機構を採用できる。
Also, since the soft mechanism of the grand piano can move the action, the hammer moves a little due to the movement of the action, the part of the hammer head that hits the string hits the soft mountain part and makes a soft sound I can do it.
In the configuration of the present invention, the same soft sound component mechanism can be adopted since the damper device and the damper device are separately configured in the same manner as this.
又、ダンパー装置にばねを使用しないので、打弦の際前述のばねっぽいタッチを回避でき、グランドピアノと同様のタッチ感、アフタータッチ、レットオフ感が得られる。 Also, since no spring is used for the damper device, the above-mentioned spring-like touch can be avoided when hitting the string, and the touch feeling, after touch and let-off feeling similar to those of a grand piano can be obtained.
上記請求項2に記載のダンパー装置によれば、ダンパーレバーの前端はブラケット等に固定したダンパーフレンジに回動自在に枢支してあり、ダンパーヘッド、ダンパーワイヤー、ダンパーレバーの重量はダンパーレバー後端即ち弦に近い部分にかかっている。この為、ダンパーヘッドは枢支ピンを中心として後側即ち弦側への回動モーメントによって弦Sに接せしめられている。 According to the damper device of the second aspect, the front end of the damper lever is pivotally supported by a damper flange fixed to a bracket or the like, and the weight of the damper head, the damper wire, and the damper lever is determined after the damper lever. It rests on the end, that is, the part near the string. For this reason, the damper head is brought into contact with the string S by a pivoting moment about the pivot pin toward the rear side, that is, the string side.
そして打弦時、鍵盤3の後端が上がると突上部がダンパーレバー後端を押上げることにより、ダンパーレバーは回動し、ダンパーヘッドは弦から離れ、音の発生を許容する。
又離鍵により、ダンパーは自重により回動しダンパーヘッドは弦に当たり音の発生を防止する。
従って、ダンパー装置はダンパーヘッド、ダンパーレバー自身の自重により回動し弦に接することになりばねっぽい指の感覚を防止できる。
When the string is struck, when the rear end of the
When the key is released, the damper is rotated by its own weight, and the damper head hits the string to prevent generation of sound.
Therefore, the damper device is rotated by its own weight of the damper head and the damper lever itself and comes into contact with the string, thereby preventing the feeling of a spring-like finger.
上記請求項3に記載のダンパー装置によれば、ダンパーレバーの前端を枢支ピンにより回動自在に枢支し、ダンパーヘッド、ダンパーワイヤー、ダンパーレバーの重量がダンパーレバー後端部即ち弦に近い部分にかかっている。
このためその作動は請求項2の発明に係るものと同じである。
しかし、その構成の簡素さにより、製作、使用上至便である。
又、その重量の調整も簡単で、ダンパーレバーの材質によって例えば金属、堅木、プラスチック等の選択により重量を容易に選定できる。
According to the damper device of the third aspect, the front end of the damper lever is pivotally supported by the pivot pin so that the weight of the damper head, the damper wire, and the damper lever is close to the rear end portion of the damper lever, that is, the string. It depends on the part.
Therefore, the operation is the same as that according to the invention of
However, due to the simplicity of the configuration, it is convenient in production and use.
Also, the adjustment of the weight is simple, and the weight can be easily selected by selecting, for example, metal, hardwood, plastic, etc. according to the material of the damper lever.
上記請求項4に記載のダンパー装置によれば、ダンパーレバーはレール等の不動部に設けたダンパーフレンジに2本の腕木を適宜間隔を置いて枢支し、該腕木の下端部にダンパーレバーを夫々枢支してある。この為、ダンパーレバーは横方向に移動自在となっている。そして図4の構成はダンパーレバーは腕木の下端部に夫々枢支し、ダンパーレバー後端部にダンパーワイヤーを介してダンパーヘッドを一体的に連結してあり、該ダンパーレバーの後端部下部に鍵盤後端部設けた突上部を対峙させてある。
図5の構成は、腕木の下端部をダンパーフレンジに夫々枢支させると共に該腕木の上端部にダンパーレバーを夫々枢支してダンパーレバーの横方向への移動自在としてある。
これらの構成は、ダンパーレバー、ダンパーワイヤー、ダンパーヘッドの重量をダンパーヘッドの弦に対する押圧方向への圧力に変える構成であり、ダンパーヘッドの弦に対する接触は略全面に亘り瞬時に発音停止の機能を発揮できる。
According to the damper device of the fourth aspect, the damper lever pivotally supports two arms on a damper flange provided on a non-moving portion such as a rail at an appropriate interval, and the damper lever is provided at the lower end of the arm. Each is pivotally supported. For this reason, the damper lever is movable in the lateral direction. In the configuration of FIG. 4, the damper lever is pivotally supported at the lower end of the arm, and the damper head is integrally connected to the rear end of the damper lever via a damper wire. The upper part provided at the rear end of the keyboard is opposed.
In the configuration of FIG. 5, the lower end of the arm is pivotally supported by the damper flange, and the damper lever is pivotally supported by the upper end of the arm so that the damper lever can be moved in the lateral direction.
These configurations change the weight of the damper lever, damper wire, and damper head to the pressure in the pressing direction against the string of the damper head, and the contact of the damper head with the string has the function of instantaneously stopping sound generation over almost the entire surface. Can demonstrate.
上記請求項5に記載のダンパー装置によれば、ダンパーレバー中央下部はブラケット等に固定したダンパーフレンジに回動自在に枢支してあり、且、ダンパーヘッド、ダンパーレバーの大部分は枢支ピンより上方に位置し、更に、ダンパーヘッド、ダンパーレバーは枢支ピンより弦側に位置しているので、ダンパーヘッド、ダンパーレバーの重量はダンパーヘッドを弦側に回動させるように枢支ピンを中心とするダンパーレバーに回動モーメントを付与することになり、ダンパーヘッドを弦Sに接触させている。 According to the damper device of the fifth aspect, the lower center portion of the damper lever is pivotally supported by a damper flange fixed to a bracket or the like, and most of the damper head and damper lever are pivot pins. Since the damper head and damper lever are located closer to the string side than the pivot pin, the weight of the damper head and damper lever should be adjusted so that the damper head rotates to the string side. A turning moment is applied to the damper lever at the center, and the damper head is brought into contact with the string S.
そして打弦時、鍵盤3の後端が上がると、突上部がダンパーレバー下端を突上げることにダンパーレバーは回動し、ダンパーヘッドは弦から離れ音の発生を許容する。
又、離鍵により、ダンパーヘッドは、ダンパーヘッド、ダンパーレバーの自身を重量により枢支ピンを中心として回動し、弦に接し、音の発生を防止する。
従って、ダンパー装置に於いて、ばねや重りを設ける必要がなく装置も簡単な構成であり、製造容易且ばねや重りの調整の必要もなく使用も簡便である。
When the
In addition, by releasing the key, the damper head rotates the damper head and the damper lever itself around the pivot pin by weight, and comes into contact with the string to prevent generation of sound.
Therefore, in the damper device, it is not necessary to provide a spring or a weight, and the device has a simple configuration, and it is easy to manufacture and use is also easy without the need for adjusting the spring or the weight.

演奏者の押鍵によりウィッペン5を介してジャック7がシャンクローラー13を突上げると、ジャック7の当り部71がレギュレーティングボタン23に当たり、ウィッペン5に対して、ピン58を中心としてジャック7は回動され、その突上部72はシャンクローラー13から外れる。
When
ハンマー1は惰性で、アクションX及び鍵盤3とは離れる方向に回動し、ハンマーヘッド12が弦Sに当たり音を発生する。又、同時にこの演奏者の押鍵により、鍵盤3の後端に設けた突上部31が上昇し、ダンパーフレンジ91に枢支したダンパーレバー93の後端を押上げ、ダンパーレバー93は枢支ピン92を中心として反矢印Z方向へ回動する。この回動の結果、ダンパーワイヤー94を介して、ダンパーヘッド95は反矢印Z方向へ回動して弦Sを離れ、弦Sを自由とさせて、ハンマーヘッド12が弦Sを打つ前に楽音の発生可能な状態としている。(図2)
The hammer 1 is inertia and rotates in a direction away from the action X and the
その後、押鍵が終わり、鍵盤3が自由に解放されると鍵盤3の後端が下がる。キャプスタン4は下降する。又、同時にウィッペン5、レペティションレバー6及びハンマー1等の荷重により、更にはレペティションスプリング8の付勢力によりレペティションレバー6それに付随してジャック7が元の位置に戻る。
After that, when the key depression is completed and the
押鍵が終わると、横シャンク11Aに設けたキャッチャー14がチェック43に当り、ハンマーシャンク11が静止する。又、同時にレペティションレバー6は、レペティションスプリング8の力で押戻され、その結果、ジャック7の突上部72がシャンクローラー13の下に戻る。更にこの押鍵の終了時、鍵盤3を全て戻さないで、次の打鍵が出来、次の打鍵によりジャック7の突上部72がシャンクローラー13を突上げることが出来る。
When the key is pressed, the
これらの動作により鍵盤3が完全に元の位置に戻らずとも、次の打鍵を行なうことが出来、高速な運指に対応でき、連打性能の飛躍的な向上が為しうる。この一連の動作により回動し、往復したハンマー1は、その前端に設けたキャッチャー14がチェック43に係合し、安定する。又同時にダンパーヘッド95も自重により矢印Z方向へ回動復帰し、弦Sを押さえ楽音の発生を防止する。

本発明によれば、アップライトピアノに於いて、従来の打鍵時に、ウィッペンを介してハンマーによる打弦動作と、ダンパー動作を行なう構成を変えて、ハンマー作動機構とダンパー作動機構を夫々独立させて、ハンマー動作を打鍵によりウィッペンを介して行い、ダンパー動作は打鍵により直接作動させる構成としたことにより、グランドピアノ動作と同様にハンマーの左右方向への動きを得ることが出来た。これにより打鍵の動作によりハンマーはウィッペンを介してハンマー部の構成を替えるだけでアップライトピアノとすることが出来、極めて、量産性に富み経済的に優れたアップライトピアノを提供することが出来る。 According to the present invention, in the upright piano, the hammer operating mechanism and the damper operating mechanism are made independent by changing the configuration of performing the stringing operation by the hammer and the damper operation via the whippen in the conventional keystroke. Since the hammer operation is performed through the wippen by the keystroke and the damper operation is directly operated by the keystroke, the hammer can be moved in the left-right direction in the same manner as the grand piano operation. As a result, the hammer can be made an upright piano simply by changing the configuration of the hammer portion via the wippen by the operation of the keystroke, and it is possible to provide an upright piano that is extremely mass-productive and economically excellent.
