Description

Die Erfindung betrifft einen Stimmstock und ein Stimmstock-Werkzeug-Set sowie ein Verfahren zur Montage des Stimmstocks insbesondere in ein Streichinstrument.The invention relates to a voice post and a tuning pole tool set and a method for mounting the voice stick in particular in a stringed instrument.

Aus dem Stand der Technik ist es bekannt, dass in manche Musikinstrumente, insbesondere in Streichinstrumente ein Stimmstock zwischen Decke und Boden, vornehmlich in einem Bereich unterhalb des rechten Fußes eines Steges eingebaut wird. In der Regel ist dies ein zylindrisches Hölzchen. Dieser Stimmstock hat Einfluss auf die Klangeigenschaften des Instruments sowie dessen Stabilität, da er eine Deformation oder gar Zerstörung der Geigendecke verhindert. Schwierig dabei ist, dass beim Einbau des Stimmstocks die Länge des Hölzchens genau bestimmt und beide Enden des Hölzchens an die Wölbung einer Innenseite von Decke und Boden angepasst sein muss. Hat der Stimmstock die falsche Länge bzw. Höhe oder verändert sich die Wölbung durch Witterungsverhältnisse, kann sich das nachteilig auf den Klang des Instruments auswirken.It is known from the prior art that in some musical instruments, in particular in stringed instruments, a vocal tract is installed between the ceiling and the floor, primarily in an area below the right foot of a bridge. Usually this is a cylindrical wood. This tuning post has an influence on the sound characteristics of the instrument and its stability, as it prevents deformation or even destruction of the violin corner. The difficulty is that when installing the Stimmstocks the length of the wood must be precisely determined and both ends of the wood must be adapted to the curvature of an inside of the ceiling and floor. If the soundpost has the wrong length or height, or if the vault changes as a result of weather conditions, this can have a detrimental effect on the sound of the instrument.

Die DE 44 37 676 A1 offenbart ein Steg- und Stimmstocksystem zur Klangverbesserung von Streichinstrumenten, wobei Steg und Stimmstock auf Kegellagern gelagert werden, so dass die Enden des Stimmstocks sich an eine Innenseite von Decke oder Boden anschmiegen können. Dieses System erfordert für einen exakten Einbau des Stimmstocks ein langwieriges Anpassen der Stimmstocklänge.The DE 44 37 676 A1 discloses a bridge and reed system for improving the sound of stringed instruments, wherein the bridge and the reed are mounted on tapered bearings so that the ends of the reed can conform to an inside of the ceiling or floor. This system requires a lengthy adjustment of the length of the vocal chord for an exact installation of the voice block.

Die US 5 208 408 A beschreibt einen in der Höhe einstellbaren Stimmstock, der aus mehreren Teilen aufgebaut ist. Es ist ein erstes und ein zweites Bauteil vorgesehen, wobei das erste Bauteil eine Bohrung aufweist. Das zweite Bauteil hat einen Pfosten, der zu den Abmessungen in Breite und Länge der Bohrung des ersten Bauteils übereinstimmt. Dabei können die Einzelteile so zusammengesteckt sein, dass mittels zwischen gelegten Scheiben unterschiedlicher Größe eine Höhe des Stimmstocks in einem Bereich von einigen Millimetern eingestellt werden kann.The US 5,208,408 A describes a height adjustable tuning post, which is composed of several parts. There is provided a first and a second component, wherein the first component has a bore. The second component has a post that matches the dimensions in width and length of the bore of the first component. In this case, the items may be plugged together that a height of the voice stick can be set in a range of a few millimeters by means of between discs of different sizes.

Dabei ist es umständlich, die Höhe einzustellen, da dazu der Stimmstock mehrfach ein- und ausgebaut werden muss.It is cumbersome to adjust the height, as to the voice post must be repeatedly installed and removed.

Aus der US 2 162 595 A ist ein Stimmstock mit elastischen Endstücken und einer Längenanspassung bekannt.From the US 2 162 595 A is a voice post with elastic end pieces and a length adjustment known.

Die US 4 955 274 A offenbart einen Stimmstock aus einem faserverstärkten Kunststoff.The US 4,955,274 A discloses a voice post made of a fiber reinforced plastic.

In der US 1 466 681 A ist ein Stimmstocklängenbestimmungsgerät mit anpassbarer Länge und ohne Skala beschrieben.In the US 1 466 681 A there is described a variable length and scaleless vocal cord length determinator.

Aus der DE 39 14 591 A1 ist eine Zugposaune bekannt mit einer Mikrometerschraube zur Feineinstellung der Stimmung.From the DE 39 14 591 A1 is a trombone known with a micrometer screw to fine tune the mood.

Die US 2 145 237 A offenbart einen gewindefreien Stimmstock mit elastisch anpassbarer Länge und ein Werkzeug zur dessen Installation.The US 2 145 237 A discloses a non-threaded taper post with an elastically adjustable length and a tool for installing it.

Ausgehend von diesem Stand der Technik ist es Aufgabe der vorliegenden Erfindung, einen Stimmstock insbesondere für ein Streichinstrument bereitzustellen, der einfach einzubauen ist und der die Klangeigenschaften des Streichinstruments verbessert.Starting from this prior art, it is an object of the present invention to provide a voice post, in particular for a stringed instrument, which is easy to install and which improves the sound properties of the stringed instrument.

Diese Aufgabe wird durch einen Stimmstock mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a voice pole with the features of claim 1.

Ferner hat die vorliegende Erfindung die Aufgabe, die Montage eines solchen Stimmstocks zu erleichtern. Diese Aufgabe wird durch ein Stimmstock-Werkzeug-Set zum Einbau eines Stimmstocks zwischen Decke und Boden des Streichinstruments mit den Merkmalen des Anspruchs 6 gelöst.Furthermore, the present invention has the object to facilitate the installation of such a Stimmstocks. This object is achieved by a prong tool set for installation of a reed between the ceiling and the bottom of the stringed instrument with the features of claim 6.

Die weitere Aufgabe, eine präzise und zügige Montage eines Stimmstocks zu ermöglichen, wird durch das Verfahren zur Montage des Stimmstocks insbesondere in ein Streichinstrument mit den Merkmalen des unabhängigen Anspruchs 10 gelöst.The further object of enabling a precise and rapid assembly of a voice block is achieved by the method for mounting the voice block, in particular in a stringed instrument having the features of independent claim 10.

Weiterbildungen bzw. bevorzugte Ausführungsformen des Stimmstocks, des Stimmstock-Werkzeug-Sets sowie des Verfahrens sind in den Unteransprüchen ausgeführt.Further developments or preferred embodiments of the reed, the reed tool set and the method are set forth in the dependent claims.

Eine Ausführungsform bezieht sich auf einen Stimmstock insbesondere für Streichinstrumente, der aus zwei oder mehreren Stimmstockbauteilen zusammengesetzt ist und an seinen Stirnseiten schwenkbare Endstücke aufweist. Dabei weist das zweite Stimmstockbauteil ferner einen Gewindeabschnitt und das erste Stimmstockbauteil ein zu dem Gewindeabschnitt korrespondierendes Innengewinde auf, so dass die Stimmstockbauteile miteinander verschraubt und damit zueinander in der Höhe verstellt werden können. Erfindungsgemäß weist der Gewindeabschnitt ein Feingewinde auf. Ferner ist an einem der zwei oder mehreren Stimmstockbauteile eine Skala mit einer äquidistanten Einteilung angeordnet, wobei die Einteilung der Skala mit der Steigung des Feingewindes korrespondiert.One embodiment relates to a voice post, in particular for stringed instruments, which is composed of two or more voice post components and has pivotable end pieces on its end faces. In this case, the second voice post component further comprises a threaded portion and the first part of the voice memorandum an internal thread corresponding to the threaded portion, so that the voice post components can be screwed together and thus adjusted in height to each other. According to the invention, the threaded portion has a fine thread. Furthermore, a scale with an equidistant graduation is arranged on one of the two or more post components, the division of the scale corresponding to the pitch of the fine thread.

Der Stimmstock kann in jeder Art von Streichinstrumenten, auch in historischen Instrumenten oder in Zupfinstrumenten bzw. in sonstige Musikinstrumente mit Stimmstock ebenfalls Verwendung finden und vorteilhaft nachträglich eingesetzt werden. Dieser Stimmstock kann, dadurch dass er in der Höhe exakt verstellbar ist, insbesondere nachträglich eingebaut werden. Zudem kann der Stimmstock durch die präzise Höhenverstellung die Schwingungen von Decke und Boden des Instruments in Einklang bringen und dadurch dessen Klangeigenschaften und innere Stabilität maßgeblich verbessern. Die Abmessungen des Stimmstocks können passend für Violine, Viola, Violoncello, Kontrabass angepasst werden.The Stimmstock can also be used in any kind of stringed instruments, also in historical instruments or in plucked instruments or in other musical instruments with a reed, and can advantageously be used retrospectively. This post can, in that it is precisely adjustable in height, especially be retrofitted. In addition, the precise adjustment of the height of the peg makes it possible to harmonize the vibrations of the instrument's top and bottom, significantly improving its sound characteristics and internal stability. The dimensions of the voice block can be adapted to suit violin, viola, violoncello, double bass.

Durch das erfindungsgemäß vorgesehene Feingewinde entsteht eine höhere Reibung und feinere Einteilung als bei normalen Gewinden, da eine kleinere Steigung verwendet werden kann. Dadurch ist keine weitere bzw. separate Befestigung notwendig. Für einen Stimmstock für eine Geige kann eine Steigung in einem Bereich von 0,5 mm bis 1 mm, bevorzugt von 0,8 mm und für ein Cello eine Steigung in einem Bereich von 1 mm bis 1,5 mm, bevorzugt 1,25 mm vorgesehen sein.The inventively provided fine thread creates a higher friction and finer classification than normal threads, since a smaller pitch can be used. As a result, no further or separate attachment is necessary. For a voice post for a violin, a pitch in a range of 0.5 mm to 1 mm, preferably 0.8 mm and for a cello a pitch in a range of 1 mm to 1.5 mm, preferably 1.25 mm be provided.

Die Skala kann kontrastreich auf Folie aufgedruckt sein und ferner so bemessen sein, dass sie einen offenen Anteil des Gewindeabschnitts verdeckt. Der Gewindeabschnitt kann so zuverlässig vor Schmutz geschützt werden.The scale can be printed in high contrast on film and also be sized so that it covers an open portion of the threaded portion. The threaded section can be reliably protected from dirt.

Die Erfindung sieht in einer Weiterbildung vor, dass die Stimmstockkomponenten aus faserverstärktem Kunststoff, bevorzugt aus Carbon (kohlenstofffaserverstärkter Kunststoff) bestehen können. Dieses Material bietet den Vorteil, dass ein Feingewinde mit einer kleinen Steigung eingeschnitten werden kann. Der bisherige Stand der Technik konnte eine solche feine Skaleneinteilung nicht bieten, da in die bisher verwendeten Materialien, wie z. B. Holz, keine exakten Feingewinde eingeschnitten werden konnten. Die Oberfläche des bearbeiteten Carbons weist eine bestimme Rauheit auf, die verhindert, dass durch das Spielen des Instruments sich ein eingestellter Stimmstock verstellen kann, da das Gewinde unter dem Druck der Saiten eine hohe Reibungskraft besitzt. Auch können Materialien mit einer Kunststoffmatrix aus duroplastischem Harz, wie Epoxidharz oder thermoplastischen Kunststoffen mit veränderlichen Faseranteilen verwendet werden.The invention provides in a development that the voice post components made of fiber-reinforced plastic, preferably made of carbon (carbon fiber reinforced plastic) can exist. This material has the advantage that a fine thread can be cut with a small pitch. The prior art could not provide such a fine scale classification, as in the previously used materials such. B. wood, no exact fine thread could be cut. The surface of the machined carbon has a certain roughness, which prevents the playing of the instrument can adjust a set voice pole, since the thread has a high frictional force under the pressure of the strings. Also can Materials with a plastic matrix of thermosetting resin, such as epoxy resin or thermoplastic materials with variable fiber content can be used.

Ferner kann vorgesehen sein, dass der Stimmstock im Wesentlichen zylindrisch ist. Er kann zwei oder mehrere Befestigungsabschnitte aufweisen, die einen polygonalen Querschnitt aufweisen, bevorzugt achteckig sind. Ein solcher Querschnitt lässt sich gut mit einem Werkzeug umfassen, auch durch die engen F-Löcher einer Geige kann so auch nachträglich der Stimmstock noch in seiner Länge eingestellt werden. Es können aber auch andere, bspw. sechseckige oder zehneckige Querschnitte realisiert werden.Furthermore, it can be provided that the voice post is substantially cylindrical. It may have two or more attachment portions which have a polygonal cross-section, preferably octagonal. Such a cross-section can be well with a tool include, even through the narrow F-holes of a violin can be adjusted so the post also still in its length. However, it is also possible to realize other cross-sections, for example, hexagonal or ten-cornered.

In einer Weiterbildung der Erfindung kann vorgesehen sein, dass jedes Endstück einen teilkugelförmigen Abschnitt und eine ebene Abschlussfläche aufweist. Dabei kann an den Stirnseiten des Stimmstocks jeweils eine teilkugelförmige Ausnehmung vorgesehen sein, in der der teilkugelförmige Abschnitt aufgenommen ist. Hierdurch kann das Endstück in der Ausnehmung kippbar gelagert sein. Die ebene Abschlussfläche kann sich plan an die gekippte Wandung von Decke oder Boden anschmiegen, wodurch insbesondere an der Innenseite der weichen Fichtenholzdecke kein Abdruck erzeugt oder die Decke beschädigt werden kann.In a further development of the invention it can be provided that each end piece has a part-spherical section and a flat end surface. In this case, in each case a part-spherical recess may be provided on the end sides of the voice stick, in which the part-spherical section is received. In this way, the tail can be tiltably mounted in the recess. The flat end surface can fit flat against the tilted wall of the ceiling or floor, which in particular on the inside of the soft spruce wood ceiling produces no impression or the ceiling can be damaged.

Die Erfindung kann weiterhin vorsehen, dass die teilkugelförmige Ausnehmung zur Befestigung des Endstücks randseitig eine Umbördelung aufweist. Alternativ kann die Ausnehmung sowie das jeweilige Endstück magnetische Befestigungsmittel aufweisen, die zueinander so gepolt sind, dass das Endstück magnetisch innerhalb der Ausnehmung gehalten werden kann. Diese Befestigungsmittel dienen dazu, die beweglichen Endstücke während der Montage und einer ersten Positionierung verliersicher festzuhalten.The invention may further provide that the part-spherical recess for attachment of the end piece on the edge has a flanging. Alternatively, the recess and the respective end piece may have magnetic fastening means which are poled to one another such that the end piece can be held magnetically within the recess. These fasteners are used to hold the movable end pieces captive during assembly and a first positioning.

Höhe eingestellt werden kann und eine gute Schwingungskopplung zwischen Decke und Boden des Streichinstruments herstellen kann, ergibt sich vorteilhaft ein zu bisherigen Stimmstöcken verbesserter Klang des Instruments.By the voice pole according to the invention can be well adjusted in length and height and can produce a good vibration coupling between the ceiling and the bottom of the string instrument, advantageously results in a previous vocal chords improved sound of the instrument.

Um den Stimmstock präzise einzubauen, ist ein erfindungsgemäßes Stimmstock-Werkzeug-Set zur Montage des vorbeschriebenen Stimmstocks zwischen Decke und Boden eines Streichinstruments vorgesehen. Dieses Set umfasst neben dem Stimmstock ein oder mehrere Einstellwerkzeug(e), die jeweils einen Gabelabschnitt, einen Schaft und einen Halteabschnitt, insbesondere in Form einer Schlaufe aufweisen. Dabei ist der Schaft zum Erreichen der jeweiligen Befestigungsabschnitte des Stimmstocks bogenförmig und weist eine Länge auf, die zumindest einer Länge einer Strecke entspricht, die von einem vorbestimmten ersten Streichinstrumenten-F-Loch bis zu einer vorbestimmten Position an einem Streichinstrumentenboden entspricht. Damit kann der Stimmstock an der vorbestimmten Position unterhalb eines rechten Fußes eines Stegs einfach erreicht und eingestellt werden. Eine vorbestimmte Position im Sinne der Erfindung ist ein Bereich im Innenraum des Instruments, der unterhalb des rechten Fußes des Stegs, d. h. in der Regel der tonhöchsten Saite des Instruments, bspw. bei Geigen der E-Saite, in etwa 5 mm tiefer als die Position des Stegs liegt. Als alternatives Einstellwerkzeug kann zu dem hier vorgestellten auch ein traditionell verwendeter Stimmstocksetzer verwendet werden, wobei ein Greifbereich des Stimmstocksetzers dem Greifbereich der Einstellwerkzeuge entspricht.In order to precisely install the voice post, an inventive prong tool set for mounting the above-described voice block between the ceiling and the bottom of a stringed instrument is provided. This set comprises in addition to the voice post one or more adjustment tool (s), each having a fork portion, a shaft and a holding portion, in particular in the form of a loop. Here, the shaft is arcuate to reach the respective attachment portions of the voice block and has a length corresponding to at least a length of a distance corresponding to a predetermined first string instrument F hole to a predetermined position on a string instrument bottom. Thus, the voice pole can be easily reached and adjusted at the predetermined position below a right foot of a bridge. A predetermined position within the meaning of the invention is an area in the interior of the instrument, below the right foot of the web, d. H. usually the highest pitched string of the instrument, eg. For violins of the E-string, is located about 5 mm lower than the position of the bridge. As an alternative adjustment tool can be used for the here presented also a traditionally used Stimmstocksetzer, wherein a gripping area of the Stimmstocksetzers corresponds to the gripping area of the setting tools.

Ferner kann das Set ein zum Einbau geeignetes Einführwerkzeug zum Einführen des Stimmstocks in das Streichinstrument umfassen, wobei das Einführwerkzeug einen abgewinkelten Schaft und einen Zangenabschnitt aufweist. Das Einführwerkzeug kann eine Betätigungseinrichtung in Form eines federbelasteten Stempels aufweisen. Für kleine Stimmstöcke bei kleineren Instrumenten kann der Zangenabschnitt als einfache Zange mit zwei Zangenbacken vorliegen. Sollen größere Stimmstöcke, bspw. für Cello oder Kontrabass eingesetzt werden, kann der Zangenabschnitt des Einführwerkzeugs eine Doppelzange sein, und damit insgesamt vier Zangenbacken aufweisen. Damit kann der Stimmstock sicher gehalten und sorgsam in das Instrument durch das erste F-Loch eingeführt werden.Further, the kit may include an insertable insertion tool for insertion into the stringed instrument, the insertion tool having an angled shaft and a pincer section. The insertion tool may have an actuating device in the form of a spring-loaded punch. For small voice sticks on smaller instruments, the forceps section may be a simple forceps with two forceps jaws. If larger voice sticks, eg. For cello or double bass are used, the forceps portion of the insertion tool can be a double forceps, and thus have a total of four jaws. This allows the vocal pole to be held securely and carefully inserted into the instrument through the first F-hole.

Mit Hilfe des erfindungsgemäßen Werkzeug-Sets kann neben einem Einbau während des Baus des Streichinstruments der Stimmstock ohne Weiteres auch nachträglich nach dem Einbau von Steg und Saiten eingesetzt werden. Die genannten Einstellwerkzeuge erreichen durch ihre gebogene Form die zu erreichenden Stellen innerhalb des Streichinstruments in geeigneter Weise. So muss der Stimmstock zum Justieren der Länge u. a. aufgrund von Schräge bzw. Wölbung der Decke und des Bodens nicht immer wieder ausgebaut werden, sondern kann an Ort und Stelle verbleiben. Ein Instrumentenbauer kann sich damit zusätzliche, zeitintensive Arbeitsschritte ersparen.With the help of the tool set according to the invention, in addition to an installation during the construction of the string instrument of the vocal can be readily used also after the installation of web and strings. The As a result of their curved shape, these adjustment tools reach the points to be reached within the string instrument in a suitable manner. For example, to adjust the length, the tuning post does not have to be removed again and again, due in particular to the slope or curvature of the ceiling and the floor, but can remain in place. An instrument maker can thus save additional, time-consuming work steps.

In einer bevorzugten Weiterbildung der Erfindung können der Schaft der Einstellwerkzeuge und der abgewinkelte Schaft des Einführwerkzeugs mit einem Kunststoff umhüllt sein. Bevorzugt kann das ein Kunststoff sein, der auch für Schrumpfschläuche Verwendung findet. Damit können die empfindlichen Seitenränder der F-Löcher und die hölzerne, lackierte Decke des Streichinstruments geschont werden. Vorteilhaft kann eine farbliche Unterscheidung der Kunststoffumhüllung je nach Instrumentengattung vorgesehen sein. So kann bspw. das Einführwerkzeug generell schwarz, und Einstellwerkzeuge für Geigen rot und für Bratschen gelb sein. Die Farben sind jedoch frei zu wählen.In a preferred embodiment of the invention, the shank of the adjusting tools and the angled shaft of the insertion tool can be wrapped with a plastic. Preferably, this may be a plastic, which is also used for heat shrink tubing. Thus, the delicate side edges of the F holes and the wooden, painted ceiling of the string instrument can be spared. Advantageously, a color distinction of the plastic sheath can be provided depending on the type of instrument. For example, the insertion tool can be generally black, and setting tools for violins red and for violas yellow. The colors are free to choose.

Auch kann das erste Einstellwerkzeug einen längeren Schaft aufweisen, als das zweite Einstellwerkzeug. Vorteilhaft kann so der Stimmstock optimal positioniert werden, da dieser in der Regel unterhalb der tonhöchsten Saite des Streichinstruments gesetzt wird und damit zu einem F-Loch näher ist als zu dem anderen F-Loch. Alternativ können die Schäfte der Werkzeuge auch gleich lang sein, wobei sie einen unterschiedlichen Biegeradius aufweisen können. Der Stimmstock kann damit einfach und präzise eingebaut werden.Also, the first adjustment tool may have a longer shaft than the second adjustment tool. Advantageously, the voice pole can thus be optimally positioned, since this is usually placed below the pitch of the highest string of the stringed instrument and thus closer to an F-hole than to the other F-hole. Alternatively, the shanks of the tools can also be the same length, wherein they can have a different bending radius. The voice post can thus be easily and precisely installed.

Ein erfindungsgemäßes Verfahren zur Montage des vorbeschriebenen Stimmstocks kann mittels des vorbeschriebenen Stimmstock-Werkzeug-Sets in ein Streichinstrument erfolgen. In einem ersten Schritt wird der Stimmstock bereit gestellt und in einer vorbestimmten Höhe, die durch den Abstand zwischen Decke und Boden des Streichinstruments vorbestimmt ist, voreingestellt. Dazu kann mittels eines Stimmstock-Innentasters die Höhe zwischen Decke und Boden ausgemessen werden. Sollte ein alter, hölzerner Stimmstock ausgetauscht werden, können zunächst die Saiten abgespannt werden und der Holzstimmstock ausgebaut werden. In diesem Fall könnte die Länge des erfindungsgemäßen Stimmstocks entsprechend zu der Länge des hölzernen Stimmstocks eingestellt werden.A method according to the invention for mounting the above-described voice block can be carried out by means of the above-described vocal-tool set in a stringed instrument. In a first step, the voice pole is provided and preset at a predetermined height, which is predetermined by the distance between the ceiling and the bottom of the stringed instrument. For this purpose, the height between the ceiling and the floor can be measured by means of a sound-pencil internal button. If an old, wooden sound post is replaced, the strings can first be removed and the wooden tuning stick removed. In this case, the length of the voice block according to the invention could be adjusted according to the length of the wooden voice block.

Hiernach wird mit dem Einführwerkzeug der Stimmstock durch das erste F-Loch des Streichinstruments eingeführt und der Stimmstock an einer innerhalb des Streichinstruments vorbestimmten Position positioniert. Der Stimmstock wird dabei aufgrund seiner voreingestellten Länge leicht zwischen Decke und Boden eingekeilt. Das erste Einstellwerkzeug oder alternativ ein Stimmstocksetzer kann dabei zu Hilfe genommen werden. Die Skala ist dabei durch das erste oder auch das zweite F-Loch sichtbar, wobei der Stimmstock so eingesetzt werden sollte, dass der Skalenstrich durch das erste F-Loch gut eingesehen werden kann. Anschließend können die Werkzeuge aus dem Instrument entfernt, die Saiten auf Tonhöhe gespannt bzw. gestimmt werden und akustisch geprüft werden.After this, the insertion tool is used to insert the vocal-rod through the first F-hole of the string instrument and to position the vocal-rod at a predetermined position within the string instrument. Due to its pre-set length, the voice pole is easily wedged between the ceiling and the floor. The first adjustment tool or alternatively a Stimmstocksetzer can be taken to help. The scale is visible through the first or the second F-hole, with the voice post should be used so that the scale line through the first F-hole can be seen well. Then the tools can be removed from the instrument, the strings are stretched or tuned to pitch and acoustically tested.

Danach wird zum Einstellen der Länge des Stimmstocks der Gabelabschnitt des ersten Einstellwerkzeugs in das zweite F-Loch eingeführt und mit dem ersten Einstellwerkzeug an dem ersten Befestigungsabschnitt der erste Befestigungsabschnitt und damit das erste Stimmstockbauteil festgehalten. Ferner wird der Gabelabschnitt des zweiten Einstellwerkzeugs in das erste F-Loch eingeführt und mit dem zweiten Einstellwerkzeug der zweite Befestigungsabschnitt umfasst. Dabei erfolgt ein schrittweises Drehen des zweiten Stimmstockbauteils gemäß der Skala, womit die ebene Abschlussfläche der Endstücke an Boden und Decke des Streichinstruments angedrückt oder entspannt wird. Andrücken oder entspannen heißt hierbei, dass durch Verlängern bzw. entsprechend Verkürzen des Stimmstocks die Spannung, die der Stimmstock auf Decke und Boden aufbringt, erhöht oder erniedrigt wird. Das Drehen erfolgt so lange, bis ein optimales Klangergebnis erreicht wird, wozu nach jeder Drehung das Instrument angespielt werden kann.Thereafter, for adjusting the length of the voice stick, the fork portion of the first adjusting tool is inserted into the second F-hole and held with the first adjusting tool on the first mounting portion of the first mounting portion and thus the first voice stamp component. Further, the fork portion of the second adjustment tool is inserted into the first F-hole and the second adjustment tool includes the second attachment portion. In this case, a stepwise rotation of the second voice post component according to the scale, whereby the flat end surface of the end pieces is pressed or relaxed on the floor and ceiling of the string instrument. Pressing or relaxing here means that by extending or correspondingly shortening of the vocal cord, the tension that the voice pole applies to the ceiling and the floor is increased or decreased. The rotation takes place until an optimal sound result is achieved, after which the instrument can be played after each rotation.

Dies ermöglicht neben einem Einbau während der Fertigung des Instruments auch ein nachträgliches Bestücken - Steg und Saiten müssen nicht mehr ausgebaut werden, sondern können an Ort und Stelle bleiben. Ferner kann das Verfahren umgekehrt auch zum Ausbau des Stimmstocks eingesetzt werden; hierbei erfolgt der Ablauf des Verfahrens umgekehrt.In addition to installation during the manufacture of the instrument, this also allows retrofitting - the bridge and strings no longer need to be removed, but can remain in place. Furthermore, the method can conversely, also be used to expand the Stimmstocks; In this case, the procedure is reversed.

Die erfindungsgemäße Vorrichtung bezieht sich auf einen Stimmstock 1 für Streichinstrumente.The device according to the invention relates to a vocal head 1 for stringed instruments.

Nach Fig. 1 und 2 weist der Stimmstock 1 in einem unteren Bereich der Figur ein erstes Stimmstockbauteil 2 mit einem ersten Befestigungsabschnitt 9a auf. Ferner hat der Stimmstock 1 ein zweites Stimmstockbauteil 3 mit einem zweiten Befestigungsabschnitt 9b. Die Befestigungsabschnitte 9a, 9b sind im Querschnitt achteckig, um von einem Werkzeug gut erfasst werden zu können und auch um wenige Grad gegeneinander bewegt bzw. verdreht werden zu können.To Fig. 1 and 2 the voice post 1 in a lower portion of the figure, a first voice post component 2 with a first attachment portion 9a. Further, the voice pole 1 has a second voice block component 3 with a second mounting portion 9b. The attachment portions 9a, 9b are octagonal in cross-section to be well grasped by a tool and also by a few degrees against each other to be moved or rotated.

Das zweite Stimmstockbauteil 3 weist einen Gewindeabschnitt 7 auf, der in ein korrespondierendes Innengewinde 8 des ersten Stimmstockbauteils 2 eingreift. Die beiden Gewinde (Außengewinde des Gewindestocks 7 und Innengewinde 8) sind als Feingewinde ausgebildet.The second voice post component 3 has a threaded portion 7, which engages in a corresponding internal thread 8 of the first voice post component 2. The two threads (external thread of the threaded rod 7 and internal thread 8) are formed as a fine thread.

Das am Gewindeabschnitt 7 vorliegende Feingewinde ist so geschnitten, dass eine Einteilung der Skala 10 mit der Steigung des Feingewindes korrespondiert. Unterhalb der Skala 10 ist auf dem ersten Stimmstockbauteil 2 ein Skalenstrich 10a angeordnet. Dabei ist die Skala 10 so mit dem zweiten Stimmstockbauteil 3 gekoppelt, dass bei Verdrehen des zweiten Stimmstockbauteils 3 relativ zu dem ersten Stimmstockbauteil 2, die Skala 10 sich mitbewegt und der Skalenstrich 10a an Ort und Stelle bleibt.The fine thread present on the threaded section 7 is cut so that a division of the scale 10 corresponds to the pitch of the fine thread. Below the scale 10, a scale line 10a is arranged on the first part of the vocal horn 2. In this case, the scale 10 is coupled to the second voice post component 3 such that upon rotation of the second voice post component 3 relative to the first voice post component 2, the scale 10 moves along and the scale line 10a remains in place.

Ein Drehen eines Stimmstockbauteils gegenüber dem Anderen um einen Skalenstrich hat eine Umdrehung des Feingewindes und damit eine Erhöhung oder Verkürzung des gesamten Stimmstocks 1 zur Folge, so dass mit einer vollständigen Umdrehung des einen Bauteils gegenüber dem anderen eine Verlängerung oder Verkürzung des Stimmstocks um einen Skalenstrich erreicht wird. Die Skala soll Schritte von 0,022 mm ermöglichen, so dass eine Drehung um einen Skalenstrich einer Erhöhung oder Erniedrigung des Stimmstocks 1 um diesen Betrag bewirkt.Turning a vocal-piece component relative to the other by a scale mark results in one revolution of the fine thread and thus in an increase or decrease in the total length of the vocal piece 1, so that a complete revolution of one component relative to the other achieves an extension or shortening of the vocal column by one scale line becomes. The scale is intended to allow steps of 0.022 mm so that rotation about one scale stroke causes an increase or decrease of the voice block 1 by that amount.

In beiden Stirnseiten 4 der Stimmstockbauteile 2,3 und damit des Stimmstocks 1 ist jeweils eine teilkugelförmige Ausnehmung 6 vorgesehen, die jeweils ein Endstück 5 aufnehmen kann. Das Endstück 5 weist einen teilkugelförmigen Abschnitt 5a auf, wobei dessen Abmessungen mit den Abmessungen der Ausnehmung 6 korrespondieren, so dass das Endstück 5, wenn es mit dem teilkugelförmigen Abschnitt 5a in der Ausnehmung 6 eingesetzt ist, kippbar darin gelagert ist. Nach oben bzw. unten in der Figur ragend schließt das jeweilige Endstück 5 mit einer ebenen Abschlussfläche 5b ab, die bei Einbau in ein Streichinstrument an einer Innenfläche einer Decke oder eines Bodens anliegen soll. Durch die kippbare Lagerung kann sich das Endstück 5 der Krümmung der genannten Innenfläche auch aufgrund von Witterungseinflüssen den Wölbungen von Decke und Bodenanpassen.In both end faces 4 of the Stimmstockbauteile 2.3 and thus of the Stimmstocks 1 each have a part-spherical recess 6 is provided, each of which can accommodate a tail 5. The end piece 5 has a part-spherical portion 5a, wherein its dimensions correspond to the dimensions of the recess 6, so that the end piece 5, when it is inserted with the part-spherical portion 5a in the recess 6, is tiltably mounted therein. Projecting upwards or downwards in the figure, the respective end piece 5 terminates with a flat end face 5b which, when installed in a stringed instrument, is intended to rest against an inner surface of a ceiling or a floor. Due to the tiltable mounting, the end piece 5 of the curvature of said inner surface can also adapt to the curvature of the ceiling and floor due to the effects of weather.

In der Ausnehmung 6 kann an deren Boden ein erstes magnetisches Element vorgesehen sein, das mit einem zweites magnetischen Element, das entgegengesetzt zum ersten magnetischen Element gepolt ist, an einer korrespondierenden Fläche des Endstücks eine magnetische Befestigungseinrichtung bilden kann (nicht figurativ dargestellt). Auch kann ein Rand der Ausnehmung 6 umbördelt sein, um das Endstück 5 in der Ausnehmung 6 zu halten und die Kipp-Lagerung zu führen.In the recess 6 may be provided at the bottom thereof a first magnetic element which may be formed with a second magnetic element, which is polarized opposite to the first magnetic element, on a corresponding surface of the tail a magnetic fastening device (not shown figuratively). Also, a border can the recess 6 be beaded to hold the tail 5 in the recess 6 and to guide the tilting storage.

Sämtliche Bauteile des Stimmstocks 1 können aus Carbon oder einem dazu ähnlichen Material mit hoher Festigkeit und Steifigkeit gefertigt werden.All components of the tongs 1 can be made of carbon or a similar material with high strength and rigidity.

Fig. 3 zeigt einen Querschnitt durch eine Geige, in die der Stimmstock 1 eingesetzt ist, wobei der Stimmstock 1 zwischen Decke 21 und Boden 22 eingeklemmt ist. Der Stimmstock 1 ist zwischen Decke 21 und Boden 22 unterhalb eines rechten Fußes 23a eines Stegs 23 positioniert. Links und rechts des Stegs 23 sind jeweils Öffnungen ausgebildet, ein erstes, rechtes F-Loch 24 und ein zweites, linkes F-Loch 25. Fig. 3 shows a cross section through a violin, in which the vocal pot 1 is inserted, the prong 1 is clamped between the ceiling 21 and floor 22. The voice post 1 is positioned between the ceiling 21 and the bottom 22 below a right foot 23 a of a web 23. Openings are respectively formed on the left and right of the web 23, a first, right-hand F-hole 24 and a second, left-hand F-hole 25.

In den folgenden Fig. 4 und 5 sind die unterschiedlichen Teile eines Stimmstock-Werkzeug-Sets dargestellt, mit dem der Stimmstock 1 in ein Streichinstrument eingebaut werden kann.In the following Fig. 4 and 5 show the different parts of a vocal-tool set, with which the vocal head 1 can be installed in a stringed instrument.

Die Fig. 4 zeigt ein zu dem Werkzeugset gehörendes Einführwerkzeug 16, das einen abgewinkelten Schaft 17 und einen Greifbereich mit einem Zangenabschnitt 18 aufweist. Eine Betätigungseinrichtung in Form eines federbelasteten Stempels 19 und eines Griffs 20 sind an einem dem Zangenabschnitt 18 abgewandten Ende des Einführwerkzeugs 16 angeordnet.The Fig. 4 shows an insertion tool 16 belonging to the tool set, which has an angled shaft 17 and a gripping area with a forceps section 18. An actuating device in the form of a spring-loaded punch 19 and a handle 20 are arranged on an end of the insertion tool 16 facing away from the forceps section 18.

In Fig. 5 sind weitere Teile des erfindungsgemäßen Werkzeug-Sets dargestellt, das u. a. zwei Einstellwerkzeuge 11,12 umfasst. Beide Einstellwerkzeuge 11,12 sind im Wesentlichen gleich aufgebaut: Jedes Einstellwerkzeug 11,12 weist an einem Wirk-Ende eine Werkzeuggabel 14 auf, deren Größe auf den jeweilig einzusetzenden Stimmstock angepasst ist. Ferner ist die Größe der Werkzeuggabel 14 so bemessen, dass sie mit den Abmessungen der Befestigungsabschnitte 9a, 9b korrespondiert. Die Einstellwerkzeuge 11,12 weisen weiterhin an dem zu der Gabel 14 entgegen gesetzten Ende eine Halteschlaufe 15 auf, womit ein Geigenbauer die Einstellwerkzeuge 11,12 ergreifen kann. Die Halteschlaufe 15 ist mit der Werkzeuggabel 14 über einen gebogenen Schaft 13 verbunden. Der gebogene Schaft 13 des ersten Werkzeugs 11 ist dabei länger ausgebildet als der Schaft 13 des zweiten Werkzeugs 12. Damit kann der Geigenbauer zum Einsetzen bzw. an Position Festhalten des Stimmstocks 1 innerhalb des Instruments das erste Einstellwerkzeug 11 und zum Drehen und Einstellen der Höhe das zweite Einstellwerkzeug 12 einsetzen. Dadurch, dass der Stimmstock 1 an einer vorbestimmten Stelle innerhalb des Instruments, wie Fig. 3 zeigt, angeordnet werden muss, das näher zu dem ersten F-Loch 24 liegt als zu dem zweiten F-Loch 25, kann durch die unterschiedliche Länge der Werkzeuge diese Differenz ausgeglichen werden und der Stimmstock 1 mit beiden Einstellwerkzeugen 11,12 gut erreicht und eingestellt werden. Auch nachträgliche Einstellungen lassen sich dadurch vornehmen.In Fig. 5 are further parts of the tool set according to the invention shown, which includes, inter alia, two adjusting tools 11,12. Both adjusting tools 11,12 are constructed substantially the same: each adjusting tool 11,12 has at a kneading end a tool fork 14, the size of which is adapted to the particular use of the vocal stock. Further, the size of the tool fork 14 is sized to correspond to the dimensions of the mounting portions 9a, 9b. The adjusting tools 11,12 continue to have at the opposite end of the fork 14 a retaining loop 15, with which a violin maker can take the adjusting tools 11,12. The retaining loop 15 is connected to the tool fork 14 via a bent shaft 13. The bent shaft 13 of the first tool 11 is formed longer than the shaft 13th of the second tool 12. Thus, the violin maker for inserting or in position holding the Stimmstocks 1 within the instrument, the first setting tool 11 and for rotating and adjusting the height of the second adjustment tool 12. Characterized in that the voice post 1 at a predetermined location within the instrument, such as Fig. 3 shows, must be arranged, which is closer to the first F-hole 24 than to the second F-hole 25, can be compensated for by the different length of the tools this difference and the voice post 1 with both adjusting tools 11,12 well reached and set become. Subsequent settings can also be made.
