Description

Die Erfindung betrifft ein Doppelrohrblatt für Blasinstrumente, bestehend aus zwei im Wesentlichen gleichen Rohrblattzungen aus Kunststoff, die entlang ihrer Längsränder miteinander verbindbar sind, wobei die beiden Rohrblattzungen jeweils aus einem instrumentenseitigen Befestigungsabschnitt und einem daran angrenzenden Blattabschnitt bestehen, wobei die Rohrblattzungen im Bereich des Befestigungsabschnittes eine im Wesentlichen halbrunde Form aufweisen, und wobei im Bereich des Blattabschnittes die Oberseiten der Rohrblattzungen im Querschnitt leicht nach außen gewölbt sind und die Rohrblattzungen an ihrem freien Ende zwischen sich einen schmalen, gewölbten Luftspalt frei lassen, und wobei die Rohrblattzungen Versteifungselemente aus Kunststoff aufweisen, die sich im Wesentlichen über die gesamte Länge des Blattabschnittes erstrecken, sowie die Verwendung eines derartigen Doppelrohrblattes.The invention relates to a double reed for wind instruments, consisting of two substantially identical reeds of plastic, which are connected to each other along their longitudinal edges, wherein the two reed blades each consist of an instrument-side mounting portion and an adjoining leaf portion, the reeds in the region of the attachment portion a have substantially semicircular shape, and wherein in the region of the blade portion, the upper sides of the reeds are curved slightly outwardly in cross-section and leave the reed blades at its free end between them a narrow, curved air gap, and wherein the reeds have stiffening elements made of plastic, the extend substantially over the entire length of the blade portion, as well as the use of such a double-tube sheet.

Zahlreiche Blasinstrumente verwenden zur Tonerzeugung Mundstücke mit als Rohrblätter ausgebildeten Zungen, die von einem Luftstrom zum Schwingen gebracht werden. Dabei unterscheidet man zwischen Einfach- und Doppelrohrblättern. Einfachrohrblätter werden insbesondere bei Mundstücken von Klarinetten und Saxophonen verwendet, wohingegen Holzblasinstrumente wie Oboen und Fagotte, aber auch Dudelsäcke, Doppelrohrblätter verwenden.Numerous wind instruments use mouthpieces with tone-forming tongues, which are vibrated by a stream of air. A distinction is made between single and double tube sheets. Single-reed sheets are used in particular for mouthpieces of clarinets and saxophones, whereas woodwind instruments such as oboes and bassoons, but also bagpipes, double-reed sheets use.

An die Qualität der Rohrblätter werden hohe Anforderungen gestellt. Aufgrund ihrer klanglichen Eigenschaften werden die Rohrblätter bisher in einem aufwändigen manuellen Fertigungsprozess überwiegend aus Naturmaterial (Schilfrohr) hergestellt. Naturrohrblätter haben jedoch den Nachteil, dass sich ihre Funktion durch den Gebrauch, die Luftfeuchtigkeit und die Temperatur verändert. Außerdem müssen derartige Rohrblätter eingespielt werden, um sie an das gewünschte Schwingungsverhalten anzupassen. Da das Material altert, ist die Lebensdauer der Rohrblätter aus Naturmaterial zudem begrenzt.The quality of the reeds is subject to high demands. Due to their sonic properties, the reed blades have hitherto been produced in a complex manual production process mainly from natural material (reed). However, natural cane leaves have the disadvantage that their function is changed by the use, the humidity and the temperature. In addition, such reeds must be recorded to them to the adapt desired vibration behavior. As the material ages, the life of the reeds of natural material is also limited.

Daher sind in der DE 25 21 472 B2 bereits Zungen oder Blätter zur Verwendung bei musikalischen Blasinstrumenten wie Oboen und Fagotte beschrieben, bei denen die aus natürlichem Rohrmaterial bestehenden Zungen durch solche aus Kunststoff ersetzt werden. Da der Aufbau und die Herstellungsweise solcher Kunststoffrohrblätter der Bauweise von Naturrohrblättern gleicht, ergeben sich jedoch Nachteile aufgrund der physikalischen Eigenschaften der verwendeten Kunststoffe.Therefore, in the DE 25 21 472 B2 have already described tongues or blades for use in musical wind instruments such as oboes and bassoons, in which the tongues made of natural tube material are replaced by those made of plastic. However, since the construction and the manner of manufacturing such plastic pipe sheets is similar to the construction of natural pipe sheets, there are disadvantages due to the physical properties of the plastics used.

Die Dokumente US 2,388,822 A1 und US 2,374,579 A1 offenbaren eine Ausführung von Doppelrohrblättern aus Kunststoff, wobei eine Außenhülse die zwei Blattzungen zusammenhält, und zusätzlich für eine gute Abdichtung des Doppelrohrblattes mit der Innenhülse sorgt.The documents US 2,388,822 A1 and US 2,374,579 A1 disclose an embodiment of plastic double-tube sheets, wherein an outer sleeve holds the two tabs together, and additionally provides a good seal of the double-tube sheet with the inner sleeve.

Bisher werden bei der Herstellung von Doppelrohrblättern die beiden Rohrblattzungen um eine Metallhülse gelegt und mittels einer außen liegenden Fadenwicklung an dieser befestigt. Durch das Einbinden, d.h. das Aufbringen des Fadens und die dadurch entstehende Spannung wird der Schilf derart umgeformt, dass er sich um die Metallhülse herumschmiegt. Die dabei auf die Rohrblattzungen einwirkende Spannung hat Einfluss auf das Schwingungsverhalten des den Ton erzeugenden Blattabschnittes der Rohrblattzungen. Damit die Rohrblattzungen frei schwingen können, muss beim Einbinden der Faden in einem genau definierten Abstand zum Hülsenrand abschließen. Weicht das Ende der Fadenwicklung auch nur geringfügig von einer optimalen Position zum Hülsenrand ab, ergeben sich Probleme mit Klang, Intonation und Spieldruck des Rohrblatts.So far, the two tube sheet tongues are placed around a metal sleeve and attached by means of an external thread winding at this in the production of double tube sheets. By incorporating, i. the application of the thread and the resulting tension is the reed reshaped so that it wraps around the metal sleeve. The case acting on the reeds tension has an influence on the vibration behavior of the clay-generating blade portion of the reed blades. In order for the reed blades to oscillate freely, the thread must be locked at a precisely defined distance from the edge of the sleeve. If the end of the thread winding deviates only slightly from an optimum position to the edge of the sleeve, problems arise with sound, intonation and playing pressure of the reed.

Die Spannung des Fadens in Verbindung mit der optimalen Position zum Hülsenrand bewirkt eine Deformation des unter der Wicklung liegenden Zungenmaterials und erzeugt einen Spannungsverlauf, der bis in die Rohrblattspitze wirkt und die Funktionsweise des Doppelrohrblatts entscheidend beeinflusst.The tension of the thread in conjunction with the optimum position to the sleeve edge causes a deformation of the lying below the winding tongue material and creates a voltage curve that acts up in the reed tip and affects the functioning of the double-tube significantly.

Auch bei der Einbindung eines Kunststoffdoppelrohrblattes findet aufgrund der Fadenspannung eine Umformung / Verdrängung des Kunststoffes statt. Da sich Kunststoff im Vergleich zum Schilfmaterial jedoch abweichend verhält, entstehen bei dieser Verbindungsweise neue, zusätzliche Probleme. Auch bei Kunststoffzungen muss ein genau definierter Abstand zur Hülse eingehalten werden, um keine Klangbeeinträchtigungen zu bekommen.Even with the integration of a plastic double-tube sheet, a deformation / displacement of the plastic takes place due to the thread tension. However, since plastic behaves differently in comparison to the reed material, this connection method creates new, additional problems. Even with plastic tongues a well-defined distance to the sleeve must be kept in order to get no sound impairments.

Aufgabe der vorliegenden Erfindung ist es daher, ein Doppelrohrblatt für Blasinstrumente der eingangs genannten Art zu schaffen, das die Vorteile der aus Naturmaterial hergestellten Doppelrohrblätter hinsichtlich ihrer klanglichen Eigenschaften und die Vorteile der synthetischen Doppelrohrblätter hinsichtlich ihrer Unempfindlichkeit gegen mechanische Belastungen vereint und gleichzeitig eine einfache, sichere und reproduzierbare Herstellung ermöglicht.Object of the present invention is therefore to provide a double reed for wind instruments of the type mentioned above, which combines the advantages of the double tube sheets made of natural material in terms of their sonic properties and the advantages of synthetic double reed leaves in terms of their insensitivity to mechanical stresses and at the same time a simple, secure and reproducible production allows.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass im Übergangsbereich zwischen dem Befestigungsabschnitt und dem Blattabschnitt auf der Oberseite der Rohrblattzungen ein Absatz ausgebildet ist, der einen Anschlag für eine von dem instrumentenseitigen Ende der Rohrblattzungen auf die aufeinandergelegten Rohrblattzungen aufschiebbare Hülse bildet, die in ihrer Form an die beiden aufeinanderliegenden Rohblattzungen angepasst ist, und dass die beiden Rohrblattzungen im Bereich der Befestigungsabschnitte durch die von außen aufgebrachte Hülse formschlüssig miteinander verbunden sind. Der Absatz definiert dabei einen Anschlag, bis zu dem die Hülse über die Kunststoffrohrblätter geschoben und dort befestigt wird. Damit wird eine eindeutige Reproduzierbarkeit des Schwingungsverhaltens der Rohrblattzungen erreicht. Die erfindungsgemäße Ausbildung und Anordnung der Hülse ermöglicht es, die Kunststoffrohrblattzungen großflächig zusammenzuhalten und zu stabilisieren. Außerdem erzeugt die Hülse einen definierten Druck auf die in Längsrichtung leicht gewölbten Kunststoffrohrblattzungen, der die Seitenränder der aneinander anliegenden Rohrblattzungen verschließt und abdichtet.This object is achieved in that in the transition region between the mounting portion and the blade portion on the upper side of the reeds a shoulder is formed, which forms a stop for a slidable from the instrument side end of the reeds on the superimposed reeds sleeve, which in shape the two superimposed Rohblattzungen is adapted, and that the two pipe blade tongues are positively connected to each other in the region of the fastening portions by the sleeve applied from the outside. The paragraph defines a stop, to which the sleeve is pushed over the plastic tube sheets and fastened there. This achieves a clear reproducibility of the vibration behavior of the reed blades. The inventive construction and arrangement of the sleeve makes it possible to hold together and stabilize the plastic tube blade tongues over a large area. In addition, the sleeve produces a defined pressure on the slightly curved in the longitudinal direction plastic tube blade tongues, which closes and seals the side edges of the adjoining tube sheet tongues.

Dadurch, dass die Rohrblattzungen ausschließlich durch die außenliegende Hülse zusammengefügt werden, wird die bekannte Verbindung zwischen den Rohrblattzungen und dem Musikinstrument in Form einer innenliegenden Hülse erfindungsgemäß durch eine ausschließlich durch die Formgebung der Rohrblattzungen beeinflusste Luftführung ersetzt.Characterized in that the pipe blade tongues are joined together exclusively by the outer sleeve, the known connection between the reeds and the musical instrument in the form of an inner sleeve is replaced according to the invention by an exclusively influenced by the shape of the reeds ventilation air.

Gemäß einer Ausgestaltung der Erfindung sind die im Bereich des Blattabschnittes vorgesehenen Versteifungselemente als in Längsrichtung der Rohrblattzungen verlaufende Verstärkungsrippen ausgebildet. Diese Verstärkungsrippen werden dabei vorteilhafterweise von (Kohlefaser-) Stäben bzw. Federn gebildet, die in Längsrichtung in dem Grundwerkstoff des Rohrblattes eingebettet sind. Durch den von der außen liegenden Hülse erzeugten Druck entsteht, übertragen durch die in die Verstärkungsrippen eingebetteten Stäbe bzw. Federn, eine definierte Vorspannung im gesamten Blattabschnitt, die das Schwingungsverhalten der Rohrblattzungen beeinflusst.According to one embodiment of the invention, the stiffening elements provided in the region of the blade section are designed as reinforcing ribs extending in the longitudinal direction of the tube blade tongues. These reinforcing ribs are advantageously formed by (carbon fiber) rods or springs, which are embedded in the longitudinal direction in the base material of the reed. Due to the pressure generated by the outer sleeve, transmitted by the rods or springs embedded in the reinforcing ribs, a defined pretension is created in the entire blade section, which influences the vibration behavior of the reed blade tongues.

Damit die Kunststoffrohrblattzungen bei Herstellung und Verwendung nicht deformiert werden und um eine Reproduzierbarkeit der Verbindung zu gewährleisten, soll die Hülse erfindungsgemäß aus einem formstabilen Material, insbesondere einem metallischen Werkstoff bestehen.So that the plastic tube blade tongues are not deformed during production and use and to ensure a reproducibility of the connection, the sleeve should, according to the invention, consist of a dimensionally stable material, in particular a metallic material.

Um eine sichere Verbindung der Hülse mit den beiden Rohrblattzungen zu gewährleisten, wird die Hülse vorzugsweise mit den Rohrblattzungen verklebt.In order to ensure a secure connection of the sleeve with the two pipe blade tongues, the sleeve is preferably glued to the pipe blade tongues.

Die luftdichte Abdichtung zwischen den Rohrblattzungenhälften lässt sich erfindungsgemäß dadurch verbessern, dass sie in Längsrichtung eine ganz minimale Wölbung aufweisen.The airtight seal between the tube sheet halves can be inventively improved by having a very minimal curvature in the longitudinal direction.

Die Verbindung zwischen dem Doppelrohrblatt und dem Blasinstrument wird in Anlehnung an die bisher übliche Befestigungsart dadurch hergestellt, dass am unteren Ende des Doppelrohrblattes eine den unteren Abschnitt der Hülse und/oder des nach unten vorstehenden Befestigungsabschnittes der Rohrblattzungen übergreifende Fadenwicklung oder ein Kork angebracht sind.The connection between the double-reed and the wind instrument is made in accordance with the usual manner of attachment, that at the lower end of the double reed a the lower portion of the sleeve and / or the downwardly projecting mounting portion of the reeds cross-thread thread winding or a cork are attached.

Eine besondere Verwendung findet das erfindungsgemäße Doppelrohrblatt als Dudelsack-Doppelrohrblatt, insbesondere für die Spielpfeife der schottischen Great Highland Bagpipes.A special use is the double-reed according to the invention as a bagpipe double reed, especially for the whistle of the Scottish Great Highland Bagpipes.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels näher erläutert, das in der Zeichnung dargestellt ist. Dabei bilden alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger Kombination den Gegenstand der Erfindung, unabhängig von Ihrer Zusammenfassung in den Ansprüchen oder deren Rückbezügen.The invention will be explained in more detail with reference to an embodiment which is shown in the drawing.

Das in Fig. 1 dargestellte Doppelrohrblatt 1 besteht aus zwei gleichen, aufeinandergelegten Rohrblattzungen 2, 3 aus einem Kunststoffverbundmaterial. Die Form und Größe des Doppelrohrblattes entspricht weitgehend der Form und Größe der herkömmlichen Doppelrohrblätter aus Naturmaterial, insbesondere aus Schilfrohr. In dem Kunststoffmaterial sind in Längsrichtung der Rohrblattzungen Kohlefaser-Stäbe 4 eingelegt, die, wie aus Fig. 2 zu ersehen ist, auf der Oberfläche der Rohrblattzungen 2, 3 als Stege ausgebildet sind. Diese verstärken die Rohrblattzungen. Damit bewirken sie ein höheres Biegemoment der Rohrblattzungen 2, 3 in Längsrichtung. Gleichzeitig beeinflussen sie deren Schwingungsverhalten.This in Fig. 1 shown double reed 1 consists of two identical, superimposed reeds 2, 3 of a plastic composite material. The shape and size of the double-reed sheet largely corresponds to the shape and size of the conventional double-reed sheets of natural material, in particular reed. In the plastic material carbon fiber rods 4 are inserted in the longitudinal direction of the tube blade tongues, which, as from Fig. 2 can be seen, are formed on the surface of the pipe blade tongues 2, 3 as webs. These reinforce the reed tongues. Thus, they cause a higher bending moment of the tube sheet tongues 2, 3 in the longitudinal direction. At the same time they influence their vibration behavior.

Die beiden Rohrblattzungen 2 und 3 werden durch eine Metallhülse 5 verbunden und stabilisiert. Die Hülse 5 wird vom instrumentenseitigen Ende 6 des Doppelrohrblattes 1 auf die beiden aufeinandergelegten Rohrblattzungen geschoben und kommt an einem auf der Oberseite der Rohrblattzungen 2 und 3 als Anschlag ausgebildeten Absatz 7 zur Anlage. Der Absatz 7 ist im Übergangsbereich zwischen dem Befestigungsabschnitt 8 und dem schwingenden Blattabschnitt 9 der Rohrblattzungen angeordnet. Durch die genaue Passform der Hülse 5 ergibt sich ein definierter Druck auf die Rohrblattzungen 2, 3. Dadurch werden die Seitenränder 10 der aufeinanderliegenden Rohrblattzungen 2 und 3 sicher verschlossen und abgedichtet.The two pipe blade tongues 2 and 3 are connected by a metal sleeve 5 and stabilized. The sleeve 5 is pushed from the instrument-side end 6 of the double tube sheet 1 on the two superimposed pipe blade tongues and comes to a formed on the top of the pipe blade tongues 2 and 3 as a stop paragraph 7 to the plant. The paragraph 7 is arranged in the transition region between the mounting portion 8 and the oscillating blade portion 9 of the reed blades. The exact fit of the sleeve 5 results in a defined pressure on the tube sheet tongues 2, 3. As a result, the side edges 10 of the mutually lying pipe blade tongues 2 and 3 are securely closed and sealed.

Wie aus Fig. 2 zu ersehen ist, sind die Oberseiten der Rohrblattzungen 2 und 3 im Bereich des Blattabschnittes 9 im Querschnitt leicht nach außen gewölbt, so dass die Rohrblattzungen an ihrem freien Ende 11 zwischen sich einen schmalen, gewölbten Luftspalt 12 frei lassen. Außerdem weisen die Rohrblattzungen 2, 3 in Längsrichtung verlaufende Verstärkungsrippen 13 auf, in denen die Kohlefaser-Stäbe bzw. Federn 4 eingelassen sind.How out Fig. 2 can be seen, the tops of the reeds 2 and 3 in the region of the blade portion 9 in cross-section slightly curved outwardly, so that the reeds leaves at its free end 11 between them a narrow, curved air gap 12 between them. In addition, the pipe blades have tongues 2, 3 extending in the longitudinal direction of reinforcing ribs 13, in which the carbon fiber rods or springs 4 are embedded.

Fig. 3 zeigt, dass die Rohrblattzungen 2, 3 im Bereich des Befestigungsabschnittes 8 eine im Wesentlichen halbrunde Form aufweisen. Die die Rohrblattzungen 2, 3 im Befestigungsabschnitt 8 außen umgreifende Metallhülse 5 ist in ihrer Form genau auf die beiden Rohrblattzungen 2 und 3 angepasst und stabilisiert die aufeinandergelegten Rohrblattzungen. Zur sicheren Befestigung der Hülse 5 an dem Doppelrohrblatt 1 ist diese durch Verkleben fest mit den Rohrblattzungen 2, 3 verbunden. Fig. 3 shows that the tube sheet tongues 2, 3 in the region of the attachment portion 8 have a substantially semicircular shape. The tubular sleeve tongues 2, 3 in the attachment section 8 outside embracing metal sleeve 5 is adapted in shape to the two pipe blade tongues 2 and 3 and stabilizes the superimposed pipe blade tongues. For secure attachment of the sleeve 5 to the double tube sheet 1, this is firmly connected by gluing with the tube sheet tongues 2, 3.

Am unteren Ende des Befestigungsabschnittes 8 ist eine traditionelle Fadenwicklung 14 vorgesehen, die das Einsetzen und Justieren des Doppelrohrblattes 1 in ein nicht dargestelltes Musikinstrument ermöglicht.At the lower end of the attachment portion 8, a traditional filament winding 14 is provided, which allows the insertion and adjustment of the double-reed 1 in a musical instrument, not shown.

Die Form der Rohrblattzungen 2 und 3 ist der Form der bisher verwendeten Rohrblattzungen aus Naturmaterial mit der zwischen den Rohrblattzungen angeordneten Hülse nachgebildet. Diese unterscheiden sich je nach Musikinstrument. So lassen sich die Doppelrohrblätter nicht nur für Oboen und Fagotte, sondern auch als Dudelsack-Doppelrohrblatt verwenden, insbesondere für die Spielpfeife der schottischen Great Highland Bagpipes. Die Luftführung wird auch in diesem Fall durch die Formgestaltung des Doppelrohrblattes 1 bestimmt. Die optisch markante außenliegende Metallhülse 5 verbindet und stabilisiert die aufeinandergelegten Rohrblattzungen formschlüssig.The shape of the pipe blade tongues 2 and 3 is the shape of the previously used pipe blade tongues of natural material with the arranged between the pipe blade tongues sleeve modeled. These differ depending on the musical instrument. Thus, the double reeds can be used not only for oboes and bassoons, but also as a bagpipe double reed, especially for the whistle of the Scottish Great Highland Bagpipes. The air flow is also determined in this case by the design of the double tube sheet 1. The visually striking outer metal sleeve 5 connects and stabilizes the superimposed pipe blade tongues form fit.
