Description
Notenblattwender. Die Erfindung bezieht sich auf einen elektrischen Notenblattwender und bezweckt, ein Umwenden der Notenblätter ohne Unterbrechung des Spieles zu ermöglichen.Sheet music turner. The invention relates to an electrical Sheet music turner and aims to turn the sheet music over without interruption of the game.
Ein Ausführungsbeispiel ist auf der Zeichnung in schaubildlicher Weise dargestellt, und zwar zeigt: Abb. i eine Ansicht des Erfindungsgegenstandes, Abb. 2 einen Schnitt nach der Linie i-i von oben gesehen in größerem Maßstabe und Abb.3 die an einem Notenständer befestigte Vorrichtung.One embodiment is shown in the drawing in a diagrammatic manner shown, namely shows: Fig. i a view of the subject matter of the invention, Fig. 2 shows a section along the line i-i seen from above on a larger scale and Fig. 3 the device attached to a music stand.
An einer Platte A ist eine Welle C an Laschen B befestigt. An der Welle sind eine Anzahl von rechtwinklig gebogenen Hebeln D drehbar befestigt, die an ihren freien Enden Stangen H tragen. In den Hebeln D befinden sich an der Befestigungsstelle Schlitze, an die besondere Lenker E angelenkt sind. Diese sind an Federn F befestigt, die das Bestreben haben, die Lenker im Sinne des Pfeiles X nach hinten zu ziehen. An der Platte A ist außerdem ein Kurbelarm K befestigt, an dem eine Schubstange L angelenkt ist, die sich gegen den Hebel D legt. Der Kurbelarm K ist mit einem Anker versehen, der von einem Elektromagneten M angezogen wird. Eine Feder N bringt den Kurbelarm in seine Anfangslage zurück. In der Ruhelage liegt die Schubstange L auf dem obersten Hebel D auf und die Hebel E werden durch die Federn F festgehalten. Wird der Strom des Magneten geschlossen, so wird der Anker angezogen und die Schubstange I. drückt den obersten Hebel D über seine Totlage zurück. Alsdann wird er mittels des Lenkers E durch die Federn F zurückgeklappt (Abb.2), und: die Schubstange liegt auf dein folgenden Hebel D auf. Nach Einschalten des Stromes wiederholt sich derselbe Vorgang. Um den Apparat zu benutzen, wird er, wie aus Abb. 3 ersichtlich, mittels der Klemme J an einem Halter des Notenständers befestigt und hinter jedes Notenblatt eine der Stangen H geschoben. Mittels eines Fußkontaktes kann der Stromkreis zum Magneten geschlossen werden.A shaft C is attached to brackets B on a plate A. A number of right-angled levers D are rotatably attached to the shaft and carry rods H at their free ends. In the levers D there are slots at the fastening point to which special handlebars E are hinged. These are attached to springs F, which tend to pull the handlebars backwards in the direction of arrow X. A crank arm K is also attached to the plate A, to which a push rod L is articulated, which lies against the lever D. The crank arm K is provided with an armature which is attracted by an electromagnet M. A spring N brings the crank arm back to its initial position. In the rest position, the push rod L rests on the uppermost lever D and the levers E are held in place by the springs F. If the current of the magnet is closed, the armature is attracted and the push rod I. pushes the uppermost lever D back through its dead position. Then it is folded back by the springs F by means of the handlebar E (Fig. 2), and: the push rod rests on the next lever D. After switching on the power, the same process is repeated. To use the apparatus, as shown in Fig. 3, it is attached to a holder of the music stand by means of the clamp J and one of the rods H is pushed behind each sheet of music. The circuit to the magnet can be closed by means of a foot contact.
