Description

Die Erfindung betrifft ein Griffbrett für Zupfinstrumente, insbesondere Gitarren, mit quer verlaufenden Bünden zur Veränderung der Tonhöhe von längs über das Griffbrett gespannten Saiten.The invention relates to a fingerboard for plucked instruments, in particular guitars, with transverse frets for changing the pitch of strings stretched longitudinally over the fingerboard.

Bei bekannten Griffbrettern dieser Art erstrecken sich die Bünde geradlinig und aus einem Stück bestehend über das Griffbrett hinweg und haben für alle über sie hinweg laufenden Saiten den gleichen Abstand vom Steg des Zupfinstruments, der im Hinblick auf die Tonhöhe den Anfangspunkt der Saite bildet. Durch Andrücken der Saite an einen bestimmten Bund ist diese befähigt, in einer bestimmten Tonhöhe zu erklingen. Die Abstände der Bünde untereinander und vom Steg werden bisher mathematisch oder graphisch ermittelt. Es hat sich gezeigt, daß diese Abstandswerte mit den akustisch richtigen Werten nicht in Einklang sind, so daß beim Stimmen der Saite Kompromisse eingegangen werden mußten und eine hochreine Stimmung, insbesondere außerhalb des Bereiches der temperierten Stimmung nicht möglich war. So konnten insbesondere die erhöhten oder erniedrigten Töne, beispielsweise "dis" und "es" nicht voneinander unterschieden werden. Auch ergab sich, daß bei herkömmlichen Griffbrettern mit geradlinig, einstückig durchgehenden Bünden die Tonhöhen von einem zum anderen Saiten-Satz verschieden waren. Unterschiede ergaben sich auch beim Übergang von einem Saitenfabrikat auf ein anderes. Schließlich nutzen sich die Saiten durch das Spielen des Instruments im Laufe der Zeit ab, beispielsweise unter Ausbildung von Einkerbungen im Bereich der Bünde, wodurch die Stimmung ebenfalls beeinträchtigt wird. Auch hier war es bisher nicht möglich, eine genaue Nachstimmung Saite für Saite zu erreichen.In known fingerboards of this type, the frets extend in a straight line and consist of one piece over the fingerboard and have the same distance from the bridge of the plucking instrument for all strings running over them, which forms the starting point of the string with regard to the pitch. By pressing the string against a certain fret, it is able to sound at a certain pitch. The distances between the frets and from the web have so far been determined mathematically or graphically. It has been shown that these distance values are not in line with the acoustically correct values, so that compromises had to be made when tuning the string and a high-purity tuning, especially outside the range of the tempered tuning, was not possible. So especially high or low tones, for example "dis" and "es" are not distinguished from one another. It was also found that with conventional fretboards with straight, one-piece frets, the pitches differed from one string set to another. There were also differences when changing from one string to another. Finally, the strings wear out over time by playing the instrument, for example, with indentations in the fret area, which also affects the mood. Here too it has not been possible to achieve precise tuning string by string.

Es ist Aufgabe der Erfindung, ein gattungsgemäßes Griffbrett für Zupfinstrumente, insbesondere Gitarren so auszubilden, daß eine hochreine, akustisch genaue Stimmung von Saite zu Saite und von Ton zu Ton möglich ist.It is an object of the invention to design a generic fingerboard for plucked instruments, in particular guitars, in such a way that a high-purity, acoustically accurate tuning from string to string and from tone to tone is possible.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Bünde im Bereich der einzelnen, über sie gespannten Saiten in Bundelemente unterteilt, und diese Elemente in Saitenlängsrichtung auf dem Griffbrett einstellbar sind.The object is achieved in that the frets are divided into fret elements in the area of the individual strings stretched over them, and these elements can be adjusted in the longitudinal direction of the strings on the fingerboard.

Die nachstehende Beschreibung einer bevorzugten Ausführungsform der Erfindung dient im Zusammenhang mit beiliegender Zeichnung der weiteren Erläuterung. Es zeigen:

  • Fig. 1 eine schaubildliche Ansicht einer Gitarre;
  • Fig. 2 einen Ausschnitt im Bereich A der Fig. 1;
  • Fig. 3 eine Draufsicht eines einzelnen Bundelements und
  • Fig. 4 eine Schnittansicht entlang der Linie 4-4 in Fig. 3.
The following description of a preferred embodiment of the invention serves in conjunction with the accompanying drawings for further explanation. Show it:
  • Fig. 1 is a perspective view of a guitar;
  • FIG. 2 shows a detail in area A of FIG. 1;
  • Fig. 3 is a plan view of a single collar element and
  • 4 is a sectional view taken along line 4-4 in FIG. 3rd

Die in Fig. 1 dargestellte Gitarre umfaßt als typisches Zupfinstrument in bekannter Weise einen Schallkörper 1, von dem ein Hals 2 mit (schematisch angedeutetem) Wirbelbrett 3 absteht. Auf dem Hals 2 verläuft das (gewöhnlich schwarze) Griffbrett 4, welches sich ein Stück weit über den Klangkörper 1 hinweg erstreckt. Zwischen Wirbeln 5, die am Wirbelbrett 3 drehbar gelagert sindund einem Saitenhalter 6 mit Steg 7 sind sechs Saiten 8 ausgespannt, die mit Hilfe der Wirbel 5 in verschiedenen Tonhöhen gestimmt werden können. Der Ton jeder Saite läßt sich dadurch verändern (erhöhen), daß man die Saite gegen einen von mehreren, quer über das Griffbrett verlaufenden Bund 9 andrückt und hierdurch die Saitenlänge verkürzt.The guitar shown in Fig. 1 comprises as a typical plucking instrument in a known manner a sound body 1, from which a neck 2 with a (schematically indicated) peg board 3 protrudes. The (usually black) fingerboard 4 runs on the neck 2 and extends a little way beyond the sound body 1. Between strings 5, which are rotatably mounted on the peg board 3, and a tailpiece 6 with bridge 7, six strings 8 are stretched out, which can be tuned with the pegs 5 at different pitches. The tone of each string can be changed (increased) by pressing the string against one of several frets 9 running across the fingerboard and thereby shortening the string length.

Bei dem in Fig. 2 dargestellten, erfindungsgemäßen Griffbrett sind die in gegenseitigen Abständen quer über das Griffbrett 4 verlaufenden Bünde'als einzelne Bundelemente ausgebildet, über die im Griffbereich eines bestimmten Tones jeweils eine einzige gespannte Saite 8 hinweg verläuft. Die einzelnen Bundelemente 11 sind in Saitenlängsrichtung auf dem Griffbrett 4 einzeln einstellbar. Hierdurch ist es möglich, auf jeder Saite jeden Ton einzeln einzustellen und hierdurch eine hochgenaue, den jeweiligen Anforderungen genügende Stimmung zu bewirken.In the fingerboard according to the invention shown in FIG. 2, they are transverse at mutual intervals formed frets over the fingerboard 4 as individual fret elements, over which a single tensioned string 8 extends in the grip area of a certain tone. The individual fret elements 11 can be individually adjusted in the longitudinal direction of the strings on the fingerboard 4. This makes it possible to set each tone individually on each string, thereby creating a highly precise mood that meets the respective requirements.

Wie dargestellt, verlaufen die einzelnen Bundelemente bei der bevorzugten Ausführungsform der Erfindung nicht geradlinig, sondern gekrümmt, wobei der Krümmungsmittelpunkt vorzugsweise auf der dem Wirbelbrett 3 zugekehrten Saite des Bundelements liegt. Es hat sich ergeben, daß insbesondere bei schwierigen Griffen die gedrückten Saiten seitlich verzogen werden. Jedes Verziehen einer Saite erhöht aber den Ton. Durch die Krümmung der Bundelemente 11 wird diese erhöhte Spannung ausgeglichen. Außerdem wird durch die Krümmung der Bundelemente erreicht, daß sich die einzelnen Saiten nicht so rasch an den gleichen Stellen abnützen wie bei geraden Bünden. Die Abnützung wird vielmehr auf eine vergrößerte Fläche verlagert, was die Lebensdauer der Saite und deren Tonreinheit erhöht.As shown, the individual fret elements in the preferred embodiment of the invention do not run in a straight line, but curved, the center of curvature preferably being on the string of the fret element facing the peg board 3. It has been found that the strings that are pressed are distorted laterally, particularly in the case of difficult handles. Every warp of a string increases the tone. The curvature of the collar members 1 1, this increased voltage is compensated. In addition, the curvature of the fret elements ensures that the individual strings do not wear out as quickly in the same places as in straight frets. Rather, the wear is shifted to an enlarged area, which increases the life of the string and its tonal purity.

Anhand von Fig. 3 und 4 wird erläutert, wie die individuelle Einstellbarkeit der Bundelemente 11 bei der bevorzugten Ausführungsform der Erfindung technisch realisiert ist. Jedes Bundelement 11 umfaßt einen (gekrümmten) verhältnismäßig kurzen Quersteg 12 von halbrunder Querschnittsform (Fig. 4), auf dem die Saite 8 beim Greifen des entsprechenden Tones aufliegt. Der Quersteg 12 ist mit einem länglichen Schieber 13 starr verbunden, beispielsweise durch einstückige Ausbildung oder durch Auflötung. Der Steg 12 und Schieber 13 bestehen vorzugsweise aus Metall. Seitlich vom Schieber 13 kann der Quersteg 12 mit seiner Unterseite am Griffbrett aufliegen. Der Schieber 13 ist gleitverschieblich in einer längsweise am Griffbrett 4 verlaufenden Nut 14 angeordnet und weist ein Langloch 15 auf, welches rings von einer stufenförmigen Schulter 16 umgeben ist. Durch das Langloch 15 verläuft im wesentlichen senkrecht zum Griffbrett 4 eine Schraube 17 hindurch, deren Kopf 18 auf der Schulter 16 aufliegt und deren Schaft 19 in eine Gewindebuchse 21 eingedreht ist, die ihrerseits im Griffbrett 4 und Hals 2 der Gitarre gelagert ist. Nach Lösen der Schraube 17 kann der Schieber 13 und mit ihm der Quersteg 12 entsprechend einer gewünschten Tonhöhe eingestellt werden. Durch Anziehen der Schraube 17 wird das Bundelement 11 bei der eingestellten Tonhöhe fixiert.3 and 4 explain how the individual adjustability of the collar elements 11 is technically realized in the preferred embodiment of the invention. Each fret element 11 comprises a (curved) relatively short crosspiece 12 of semicircular cross-sectional shape (FIG. 4) on which the string 8 rests when the corresponding tone is gripped. The crosspiece 12 is rigidly connected to an elongated slide 13, for example by one-piece construction or by soldering. The web 12 and slide 13 are preferably made of metal. Laterally from the slide 13, the crossbar 12 can rest with its underside on the fingerboard. The slider 13 is slidably disposed in a groove 14 extending lengthwise on the fingerboard 4 and has an elongated hole 15 which is surrounded by a step-shaped shoulder 16. A screw 17 extends through the elongated hole 15 substantially perpendicular to the fingerboard 4, the head 18 of which rests on the shoulder 16 and the shaft 19 is screwed into a threaded bushing 21, which in turn is mounted in the fingerboard 4 and neck 2 of the guitar. After loosening the screw 17, the slide 13 and with it the crosspiece 12 can be adjusted according to a desired pitch. By tightening the screw 17, the collar element 11 is fixed at the set pitch.

Es wurde gefunden, daß sich durch die Verwendung der beschriebenen, einzeln einstellbaren Bundelemente eine Stimmung von Gitarren oder anderen Zupfinstrumenten von bisher nicht erreichbarer Tonschönheit und Reinheit erzielen läßt. Die erfindungsgemäßen Bundelemente eignen sich für Zupfinstrumente aller Art, außer für Gitarre insbesondere auch für Laute, wobei die Bundelemente vorzugsweise aus nichtmetallischen Werkstoffen, vorzugsweise Kunststoff, gefertigt werden.It has been found that by using the individually adjustable fret elements described, a tuning of guitars or other plucked instruments of previously unattainable tonal beauty and purity can be achieved. The fret elements according to the invention are suitable for plucked instruments of all kinds, except for guitar, in particular also for sounds, the fret elements preferably being made from non-metallic materials, preferably plastic.

Ferner können die erfindungsgemäßen Bundelemente auch bei Streichinstrumenten Anwendung finden, soweit dort, wie z. B. bei der Gambe, Bünde am Griffbrett vorgesehen sind.Furthermore, the fret elements according to the invention can also be used in string instruments, as far as there, such as. B. in the viol, frets are provided on the fingerboard.
