Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet eine Einrichtung zum selbsttätigen Umlegenj der Notenstütze an Klaviaturdeckeln bei Tasteninstrumenten. Das Aufklappen und das Anlegen der Stütze werden dadurch erreicht, daß die Stütze unter der Wirkung von zwei Federn steht. Die eine dieser Federn wirkt darauf hin, daß die Notenstütze stets die Stellung der Anlage an dem Instrumentendeckel einzunehmen bestrebt ist. Diese Feder d wird zweckmäßig im Gelenk der Stütze selbst angebracht, und zwar als eine um die Achse gewickelte Feder, wie dies die Fig. ι und 2 der Zeichnung, die die Einrichtung in der Gebrauchsstellung zeigen, erkennen lassen. Fig. 3 veranschaulicht den geschlossenen Deckel mit angelegter Notenstütze.The subject invention provides a means for automatically folding over j of the central support to keyboard covers at keyboard instruments. The unfolding and the application of the support are achieved in that the support is under the action of two springs. One of these springs works to ensure that the music rest always strives to assume the position of the system on the instrument cover. This spring d is expediently attached in the joint of the support itself, namely as a spring wound around the axis, as can be seen in FIGS. 1 and 2 of the drawing, which show the device in the position of use. Fig. 3 illustrates the closed lid with the music support attached.
Die zweite Feder e ist einerseits an der aufklappbaren Notenstütze, andererseits am Instrument befestigt und so angebracht, daß sie bei niedergeklapptem Deckel des Instrumentes entspannt ist, so daß die Feder d das Anlegen der Notenstütze an den Deckel unbehindert bewirken kann. Beim Öffnen des Deckels wird dagegen diese Feder e gespannt, überwindet die Wirkung der Feder d und klappt die Stütze auf.The second spring e is attached on the one hand to the hinged music rest and on the other hand to the instrument and is attached in such a way that it is relaxed when the lid of the instrument is folded down, so that the spring d can cause the music rest to be placed on the lid without hindrance. When the lid is opened, however, this spring e is tensioned, overcomes the effect of spring d and opens the support.
