Description

Tastenrausikinstrument mit zwei hintereinanderliegenden, unabhängig voneinander spielbaren Klaviaturen. Ge*genstand des Hauptpatents ist ein Tastenmusikinstrument mit zwei hintereinander- und etwas erhöht übereinanderliegenden Klavia.-turen, die unabhängig voneinander spielbar sind, und zwar in der Weise, daß sowohl getrennt auf den Klaviaturen, als auch mit ein und derselben Hand gleichzeitig auf beiden gespielt werden kann. Wenn die einzelnen Tastengriffflächen in der üblichen Weise in horizontalen Ebenen liegen, so muß die gleichzeitig auf beiden Klaviaturen spielende Hand eine schräge Lage einnehmen, was die Spielkraft und damit die Gewandtheit etwas ungünstig beeinflußt. Um dies auszugleichen, werden gemäß der Erfindung die Griffflächen der Tasten der unteren Klaviatur gegen den Spieler zu ansteigend ausgeführt.Keyboard acoustic instrument with two consecutive, independent keyboards that can be played from each other. The subject of the main patent is a keyboard musical instrument with two one behind the other and slightly elevated one on top of the other Klavia.-Doors, the are playable independently, in such a way that both separately on the keyboards, as well as with one and the same hand on both at the same time can be played. When the individual key grips in the usual way lie in horizontal planes, the one playing on both keyboards at the same time must Hand take a slanting position, what the playing power and thus the dexterity something adversely affected. To compensate for this, according to the invention, the gripping surfaces of the keys of the lower keyboard against the player performed too increasing.

In der Zeichnung ist ein Ausführungsbeispiel für einen solchen Tastensatz im Schnitt dargestellt. a ist die weiße Taste der unteren Klaviatur, b ist die schwarze Taste der gleichen Klaviatur, c ist die weiße Taste der oberen Klaviatur und d ihre schwarze Taste. Die Tasten liegen in der in dem Hauptpatent beschriebenenWeisehintereinander; dabeikönnen die weißen Tasten der unteren Klaviatur in dem Zwischenraum ihrer schwarzen Tasten auf deren Höhe erhöht sein. Außerdem sind die weißen Tasten der unteren Klaviatur, also die Tasten a und ebenso die schwarzen Tasten b, gegen den Spieler zu ansteigend ausgeführt, wie dies die Zeichnung veranschaulicht. Die Höhe dieses Anstieges richtet sich mehr oder weniger nach der Handgröße und wird durch Versuche für eine mittlere Hand ermittelt. Durch diese schräge Lage der Tastengriffflächen gewinnt die auf beiden Klaviaturen gleichzeitig spielende Hand, deren Daumen z. B. auf der unteren Klaviatur a bis b und deren übrige Finger auf den Tasten o bis d spielen, wesentlich an Kraft und Gewandtheit. Das Spiel auf der unteren Klaviatur, also auf den Tasten a und b allein, wird durch diesen schrägen Verlauf der Tasten-, oberfläche nicht gestört.In the drawing, an exemplary embodiment for such a key set is shown in section. a is the white key of the lower keyboard, b is the black key of the same keyboard, c is the white key of the upper keyboard, and d is its black key. The keys lie one behind the other in the manner described in the main patent; the white keys of the lower keyboard can be raised to their height in the space between their black keys. In addition, the white keys of the lower keyboard, that is to say the keys a and also the black keys b, are designed to rise towards the player, as the drawing illustrates. The level of this increase depends more or less on the size of the hand and is determined through tests for a medium hand. This inclined position of the key gripping surfaces wins the hand playing on both keyboards at the same time, whose thumb z. B. play on the lower keyboard a to b and the rest of the fingers on the keys o to d , significantly in strength and dexterity. The play on the lower keyboard, i.e. on the keys a and b alone, is not disturbed by this inclined course of the key surface.
