Abstract

Improved C-flap mechanism of the bass rod of bassoons for more accurate pitch, in which an intermediate joint is arranged between the grip part actuated by the musician and the closing mechanism actuating the flap cover. This joint consists of a swivel pin mounted at its ends and two arms which are connected rigidly thereto and one of which engages under the grip part and, on the actuation thereof, is pressed down while at the same time the other arm, which engages under the flap closing part, raises this closing part and closes the sound hole.

Description

Die Erfindung betrifft den im Patentanspruch definierten Gegenstand.The invention relates to that defined in the claim Object.

Das bisher übliche Fagott weist im tiefen Register den Trend auf, im Ton zu hoch zu sein. So kann das große D bis zu 5 Hz zu hoch sein und die Nachbartöne Dis und Cis sind etwa 2-3 Hz zu hoch. Deshalb ist der Fagottist bisher dazu gezwungen, mit entsprechendem Ansatz tiefer anzublasen, um zu stimmen. Aus diesem Grunde bleiben Intervalle in schneller Abfolge, die die große Oktave betreffen, immer problematisch und unsicher.The bassoon used up to now has the lower register Trend to be too high in tone. So the big D up to 5 Hz and the neighboring tones Dis and Cis are about 2-3 Hz too high. That is why the bassoonist is so far forced to blow deeper with the appropriate approach, to vote. For this reason, intervals remain in faster sequence that affect the large octave, always problematic and uncertain.

Abhilfen scheiterten am bisherigen Entwicklungsstand der Mechanik: Sie war starr, Änderungen der Tonlochpositionen waren nicht möglich. Einer Verlegung des Tonlochs standen die H- und B-Klappe im Wege und außerdem wäre bei einer Ver­ legung des Tonlochs für das große D der Aufgang der C-Klappe zu groß geworden. Eine weitere Folgeerscheinung bei Versuchen, die Stimmung zu korrigieren, bestand im Auftreten unstabiler Töne.Remedies failed due to the development status of the Mechanics: It was rigid, changes in the tone hole positions were not possible. A relocation of the tone hole stood the H and B flap in the way and also would be a ver placement of the tone hole for the large D the rise of the C-key got too big. Another sequel to attempts Correcting the mood was unstable Sounds.

Aus all diesen Gründen blieb man bisher bei den alten Tonloch­ positionen, bei der alten Konzeption der Mechanik und damit auch den vorstehend geschilderten Nachteilen.For all these reasons, the old tone hole has so far been used positions, with the old conception of mechanics and thus also the disadvantages described above.

Diese Nachteile vermeidet die erfindungsgemäße Neuerung, da die neu entwickelte Mechanik der C-Klappe der Baßstange es erlaubt, die Position des Tonloches für den Ton D ohne Rücksicht auf die Mechanik frei wählen zu können, wobei keine Ver­ änderung der übrigen Mechanik und insbesondere der gewohnten Position der Griffplatten erforderlich ist.The innovation according to the invention avoids these disadvantages, since the newly developed mechanism of the C-flap of the bass bar allows  the position of the tone hole for tone D regardless to choose the mechanics freely, no ver Modification of the other mechanics and especially the usual ones Position of the handle plates is required.

Die Erfindung wird anhand der Zeichnung näher erläutert.The invention is explained in more detail with reference to the drawing.

Das C-Griffteil besteht, wie auch bei der bisher üblichen Mechanik, aus dem um einen Lagerpunkt (1) drehbaren Klappen­ teil (2), der die Griffläche (3) trägt. Dieses Klappenteil (2) kann gegen Federkraft heruntergedrückt werden. Sein Ende trägt nicht, wie bisher üblich, den Klappendeckel, sondern endet über dem Arm (5) des Zwischengelenks, das aus einer an ihren beiden Enden gelagerten Drehachse (4) und den starr damit ver­ bundenen Armen (5, 6) besteht. Der Arm (6) seinerseits endet unter dem Klappenteil (8) des das Tonloch D gegen Federkraft verschließ­ enden Klappenschließmechanismus.The C-handle part consists, as in the previously common mechanics, of the flap part ( 2 ) which rotates about a bearing point ( 1 ) and which carries the gripping surface ( 3 ). This flap part ( 2 ) can be pressed down against spring force. Its end does not, as usual, the flap cover, but ends over the arm ( 5 ) of the intermediate joint, which consists of an axis of rotation ( 4 ) mounted at both ends and the rigidly connected arms ( 5, 6 ). The arm ( 6 ) in turn ends under the flap part ( 8 ) of the flap closing mechanism which closes the tone hole D against spring force.

Dieser Klappenteil ist um einen Lagerpunkt (7) drehbar und trägt an seinem anderen Ende den Klappendeckel (9).This flap part is rotatable about a bearing point ( 7 ) and carries the flap cover ( 9 ) at its other end.

Beim Herunterdrücken der C-Klappe auf der an üblicher Stelle zu findenden Griffplatte drückt das Ende des Klappenteils (2) den Arm (5) des Zwischengelenks herunter und dessen Arm (6) hebt den hinteren Teil des Klappenteils (8) an, so daß der am anderen Ende des Klappenteils angebrachte Klappendeckel (9) das Tonloch schließt.When pressing down the C-flap on the handle plate to be found in the usual place, the end of the flap part ( 2 ) presses down the arm ( 5 ) of the intermediate joint and its arm ( 6 ) raises the rear part of the flap part ( 8 ) so that the the flap cover ( 9 ) attached to the other end of the flap part closes the tone hole.

Wie die Arme (5, 6) dimensioniert und zu­ einander auf der Drehachse (4) angeordnet sind, ist letztlich nur durch die räumliche Anordnung des Tonlochs D und die Forderung bedingt, daß durch das Zwischengelenk das sichere Schließen des Tonloches ohne allzu große Wege erreicht werden muß. Die Arme (5, 6) können danach, wie in der Zeichnung darge­ stellt, versetzt auf der Drehachse angebracht sein, gegebenen­ fals ist aber auch eine Ausgestaltung der Art möglich, daß beide Arme miteinander fluchten und die Drehachse (4) zu einem Lagerpunkt wird.How the arms ( 5, 6 ) are dimensioned and arranged with respect to one another on the axis of rotation ( 4 ) is ultimately only due to the spatial arrangement of the tone hole D and the requirement that the secure closing of the tone hole is achieved by the intermediate joint without too great a distance must become. The arms ( 5, 6 ) can then, as shown in the drawing Darge, be offset on the axis of rotation, given fals but is also possible an embodiment of the type that both arms are aligned and the axis of rotation ( 4 ) becomes a bearing point .
