Description
jankö-Tastenwerk Die Erfindung betrifft ein jankö-Tastenwerk, das sich von den bekannten dadurch unterscheidet, daß es -an jedem Punkt der stufenförmigen Taste gleiche Spielschwere hat.jankö key mechanism The invention relates to a jankö key mechanism that differs from the known ones in that it -at every point of the step-shaped Key has the same level of difficulty.
Die Zeichnung zeigt in der Abb. i ein jankö-Vorsatz-Tasten-#verk, in der Abb.2 ein jankö-Tastenverk an einem Flügel oder Klavier.The drawing shows in Fig. I a jankö-prefix-key- # Verk, in Fig.2 a jankö-key board on a grand piano or upright piano.
Beim jankö-Vorsatz-Tastenwerk, das auf der üblichen Klaviatur eines Flügels oder eines Klaviers angebracht werden kann, ist die Taste a unten m einem zweiarmigen Hebel b, oben in einem einarmigen Hebel c gelagert und außerdem unten in dem Stift cd, oben in dem Stift e seitlich geführt. Der zweiarmige Hebel b gibt die Tastenbewegung durch den freien Hebelarm über einen weiteren zweiarmigen Übertragungshebel f an den üblichen Tastenhebel g weiter. Der- Gewichtsausgleich wird durch die Feder h, die an den zweiarmigen Hebel f angreift, hergestellt. Auf der untersten wie auf der obersten Stufe der jankö-Taste a ist die Kraft zur Bewegung der Anschlaghebel gleich groß. Dasselbe gilt auch bei dem jankö-Tastenwerk nach Abb. 2. Hier ist die jankö-Taste a anstatt in einem zweiarmigen Hebel b unmittelbar in dem zweiarmigen Tastenhebel i gelagert.With the jankö-prefix keypad, the one on the usual keyboard A grand piano or upright piano can be attached, the a button is below one two-armed lever b, mounted above in a one-armed lever c and also below in the pin cd, guided laterally in the pin e at the top. The two-armed lever b gives the key movement by the free lever arm via another two-armed transmission lever f on to the usual key lever g. The weight compensation is done by the spring h, which engages the two-armed lever f, made. On the lowest as on the top level of the jankö key a is the force to move the stop lever same size. The same applies to the jankö keypad according to Fig. 2. Here is the jankö key a instead of a two-armed lever b directly in the two-armed lever Button lever i stored.
