Description

Die Erfindung betrifft den Anschlagmechanismus eines Klaviers, besonders zur Begleitung bei Tanzmusik, dessen Saiten durch Fußbetätigung angeschlagen und die Dämpferklötze nach Freigabe der Tasten selbsttätig gegen die angeschlagenen Saiten gedrückt werden.The invention particularly relates to the strike mechanism of a piano to accompany dance music, the strings of which are struck by pressing the foot and the damper blocks automatically against the struck ones after releasing the buttons Strings are pressed.

Abb. t zeigt die Vorrichtung vor dem Anschlag einer Saite und Abb. 2 während des Anschlages.Fig.t shows the device before a string is struck and Fig. 2 during the attack.

Die von einem Fuß betätigte Taste a bewegt den Hebel b aufwärts. Hierdurch wird der Stößer c, der seitlich unter die Hammernuß d greift, diese um den Punkt c so weit drehen, daß der Fänger f den Schuh g um so viel weiter drücken kann, daß das Anschlagpolster h gegen die Saite i schlägt. Hierbei ist durch den Stempel k der Stößer c von der Hammernuß d freigekommen und der Dämpfer l wird durch den Stempel m von der angeschlagenen Saite i zurückgezogen. Wird die Taste a von dem Fuß des Spielers freigegeben, so bewegt sich der Hebel b durch das Eigengewicht wieder nach unten, die Federn zwingt den Stößer c wieder unter die Hammernuß d und die Federe drückt den Dämpfer l selbsttätig gegen die Saite i.The button a operated by one foot moves the lever b upwards. As a result, the pusher c, which grips laterally under the butt of the hammer d, will turn it around the point c so far that the catcher f can push the shoe g so much further that the stop pad h strikes against the string i. Here, the pusher c is released from the butt d by the punch k and the damper l is withdrawn from the struck string i by the punch m. If the button a is released by the player's foot, the lever b moves down again under its own weight, the springs force the pusher c back under the butt of the hammer d and the spring presses the damper l automatically against the string i.

PATENTANSPRUCH: Anschlagmechanismus eines Klaviers, dessen Saiten durch Fußbetätigung angeschlagen werden, dadurch gekennzeichnet, daß die gedrückte Taste (a) einen schwenkbar gelagerten Hebel (b) mit darauf befestigtem Fänger (f), Stempel (7n) für den Dämpfer (l) und schwenkbar, unter Wirkung der Feder (n) stehenden, die Hammernuß (d) drehenden Stößer (c) derart bewegt, daß der Schuh (g) des Hammers (h) beim Saitenanschlag in den Wirkungsbereich des Fängers (f) kommt, der Stößer (c) durch einen Stempel (k) entkuppelt wird und der Dämpfer (l) durch den Stempel (m) abgehoben wird. Claim mechanism of a piano, the strings of which are struck by foot actuation, characterized in that the pressed key (a) has a pivotable lever (b) with a catcher (f), stamp (7n) for the damper (l) and pivotable The pusher (c), which is under the action of the spring (s) and rotates the hammer butt (d), is moved in such a way that the shoe (g) of the hammer (h) comes into the range of action of the catcher (f) when the strings are struck, the pusher (c ) is uncoupled by a punch (k) and the damper (l) is lifted off by the punch (m).
