Abstract
Description
Die Erfindung betrifft eine Klappenaufhängung nach dem Oberbegriff des Anspruchs 1.The invention relates to a valve suspension according to the preamble of claim 1.
Derartige Klappenaufhängungen sind aus der DE-OS 19 03 244 oder aus der GB-PS 717 902 bekannt. Dabei ermöglicht eine Verstellung der Schraube eine Einstellung des Abstandes zwischen Klappe und Halter, wobei der Halter stets etwa tassenartig mit U-förmigem Querschnitt ausgestaltet ist. Eine pendelbeweglich oder schwenkbeweglich ausgestaltete Halterung der Klappe am Halter soll Ungenauigkeiten ausgleichen und auch dann, wenn der Halter schräg zum Tonloch steht, eine zuverlässige Abdichtung des Tonlochrandes ermöglichen.Such flap suspensions are from DE-OS 19 03 244 or known from GB-PS 717 902. Thereby enables Adjustment of the screw an adjustment of the distance between Flap and holder, the holder always about cup-like is designed with a U-shaped cross section. A pendulum or pivotally designed holder of the Flap on the holder should compensate for inaccuracies and also when the holder is at an angle to the tone hole, a reliable one Allow sealing of the tone hole edge.
In der Praxis ergeben sich dennoch stets Schwierigkeiten, eine optimale Anpassung der Klappe an das Tonloch bzw. den Tonlochrand zu erzielen. Nicht gleichzeitig auf dem ganzen Tonlochrand aufsetzende Dichtungen führen nämlich einerseits dazu, daß die gewünschte Abdichtung des Tonloches erst mit Verspätung erzielt wird. Je nach Steifigkeit der pendelbeweglichen Aufhängung der Klappe sind zudem vergleichsweise hohe Betätigungskräfte der Klappe erforderlich, um diese zuverlässig abdichtend zu schließen. Dies kann zu Verkrampfungen führen. In practice there are always difficulties, however optimal adaptation of the flap to the tone hole or the tone hole edge to achieve. Not all over the tone hole edge at the same time putting on seals on the one hand lead to that the desired sealing of the tone hole is delayed is achieved. Depending on the rigidity of the pendulum The flap suspension is also a comparatively high actuation force the flap required to seal it reliably close. This can lead to cramping.
Zudem bewirkt das verspätete Schließen des Tonloches, daß der Musiker automatisch mit einem höheren Fingerdruck arbeitet, um ein möglichst rasches, vollständiges Schließen des Tonloches zu erzielen. Auch hierdurch wird die Möglichkeit zu unerwünschten Verkrampfungen eröffnet.In addition, the delayed closing of the tone hole causes the musician automatically works with a higher finger pressure, in order to close the To achieve tone hole. This also increases the possibility unwanted cramps.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Klappenaufhängung dahingehend zu verbessern, daß eine möglichst präzise Ausrichtung der Klappe zum Tonloch mit möglichst einfachen Mitteln ermöglicht wird und unerwünschte Nebengeräusche beim Schließen der Klappe möglichst vermieden werden.The invention has for its object a generic Flap suspension to improve that Align the flap with the tone hole as precisely as possible the simplest possible means and undesirable Avoid noise when closing the flap if possible become.
Die der Erfindung zugrundeliegende Aufgabe wird durch eine Klappenaufhängung mit den Merkmalen des Anspruches 1 gelöst.The object underlying the invention is achieved by a Flap suspension solved with the features of claim 1.
Die Erfindung schlägt mit anderen Worten zwei Maßnahmen vor, nämlich erstens eine vereinfachte Klappeneinstellung zugunsten deren optimaler Auflage auf dem Tonlochrand und zweitens eine akustische Entkopplung der Klappe vom Halter und anderen Bauteilen.In other words, the invention proposes two measures before, namely firstly a simplified flap setting in favor their optimal support on the tone hole edge and secondly, an acoustic decoupling of the flap from the holder and other components.
Üblicherweise wird zur Einstellung der Klappe die Justage von Fachkräften vorgenommen. Sie erfolgt durch Verbiegen des Halters bzw. durch Verbiegen eines Klappenarms, an dem sich der Halter befindet. Durch Korrekturen und Gegenkorrekturen erfordert dieses Vorgehen einen erheblichen Zeitaufwand. Demgegenüber wird die Klappeneinstellung neuerungsgemäß vereinfacht, indem die Klappe nicht höhenbeweglich, sondern pendel- oder schwenkbeweglich am Halter befestigt ist und in ihrer jeweiligen Stellung fixierbar ist.Usually the adjustment of Specialists. It is done by bending the Holder or by bending a flap arm on which the holder is. Through corrections and counter-corrections this procedure requires a considerable amount of time. In contrast, the flap setting is new simplified by the flap not moving vertically, but pendulum or swivel is attached to the holder and in their respective position is fixable.
Die Pendelbeweglichkeit wird dadurch ermöglicht, daß die Schraube, welche die Klappe am Halter festlegt, auf der kugelsegmentförmigen Oberfläche des Halters bewegt werden kann, wobei die Klappe um ihr Zentrum in allen beliebigen Richtungen gekippt werden kann. Da bei der Herstellung von Musikinstrumenten die Länge der Halter, also deren Abstand zum Scharnierpunkt und der Abstand des Scharnierpunktes vom Tonloch, auf einfache Weise und in der Praxis stets zuverlässig ermittelt und in die Befestigung der Klappenaufhängung umgesetzt wird, ist in der Regel lediglich eine kippbewegliche Anpassung der Klappe erforderlich, um ein zuverlässiges und ringsum gleichzeitiges Abdichten des Tonlochrandes zu gewährleisten.The pendulum mobility is made possible by the fact that Screw that fixes the flap to the holder on the spherical segment Surface of the holder can be moved with the flap around its center in any direction can be tilted. Because in the manufacture of musical instruments the length of the holder, i.e. its distance from the hinge point and the distance of the hinge point from the tone hole, always reliably and easily determined in practice and is implemented in the attachment of the flap suspension, is usually just a tilting adjustment of the Flap required to be reliable and all around at the same time To ensure sealing of the tone hole edge.
Eine akustische Entkopplung der Klappe vom Halter und anderen Bauteilen wird durch eine schwingungsdämpfende Aufhängung der Klappe am Halter mittels eines schwingungsdämpfenden Zwischenstücks bewirkt.An acoustic decoupling of the flap from the holder and others Components are supported by a vibration-damping suspension the flap on the holder by means of a vibration damping Intermediate piece causes.
Vorteilhaft kann das Zwischenstück zwischen der Klappe und der Schraube vorgesehen sein. Resonanzen der Klappe und beim Aufschlagen auf den Tonlochrand auftretende Klappengeräusche können so wirkungsvoll vermieden werden, da lediglich das vergleichsweise geringe Klappengewicht gedämpft werden muß.The intermediate piece between the flap and the screw may be provided. Resonances of the flap and Flap noises when striking the tone hole edge can be avoided effectively because only the comparatively low flap weight can be damped got to.
Die Anordnung des Kugelmittelpunkts in der Ebene, in der die Klappendichtung dem Tonlochrand anliegt, stellt das ringsum gleichzeitige Anliegen der Dichtung an den Tonlochrand sicher.The arrangement of the center of the sphere in the plane in which the The flap seal lies against the edge of the tone hole simultaneous contact of the seal on the tone hole edge safely.
Daß die Klappe stets um das Zentrum ihrer Dichtung gekippt wird, wird durch die kugelsegmentförmig ausgestaltete Oberfläche der Auflageplatte sichergestellt, die auf der Außenseite des Halters anliegt.That the flap always tilted around the center of its seal through the spherical segment-shaped surface the platen ensures that on the outside of the Holder is present.
Vorteilhaft ist auch auf der zur Klappe gerichteten Unterseite des Halters eine Platte in Form einer Konterplatte vorgesehen, welche dem kugelsegmentartigen Verlauf des Halters angepaßt ist, so daß stets eine großflächige Anlage und eine sichere Führung der Klappe um den gedachten Mittelpunkt der Kugel gewährleistet ist.It is also advantageous on the underside facing the flap the holder is provided with a plate in the form of a counter plate, which adapted to the spherical segment-like course of the holder is, so that always a large area and safe management the flap around the imaginary center of the ball ensures is.
Zur Verringerung der Anzahl benötigter Bauteile kann diese
Konterplatte auf einfache Weise durch die zum Halter gerichtete
Oberfläche der mit der Schraube zusammenwirkenden Mutter
gebildet sein.
Um bei der freien Beweglichkeit der Klappe dennoch eine zuverlässige
Festlegung und ein festes Anziehen der Schraube zu
ermöglichen, können vorteilhaft die Oberfläche der Konterplatte
und die Unterseite des Halters reibfreudig ausgestaltet sein,
z. B. durch geeignete Materialpaarungen, Oberflächenrauhigkeiten
oder durch eine reibfreudige Beschichtung einer oder
beider Oberflächen.To reduce the number of components required, this counter plate can be formed in a simple manner by the surface of the nut cooperating with the screw facing the holder.
In order to enable reliable fixing and firm tightening of the screw in the free movement of the flap, the surface of the counter plate and the underside of the holder can advantageously be designed to be friction-free, e.g. B. by suitable material pairings, surface roughness or by a high-friction coating of one or both surfaces.
Auf besonders einfache Weise kann die der Außenseite des Halters anliegende Auflageplatte durch den Schraubenkopf selbst ausgestaltet sein, so daß eine sehr geringe Anzahl von Bauteilen möglich wird und hierdurch Geräuschentwicklungen oder Justierungenauigkeiten vermieden werden.In a particularly simple manner, the outside of the Holder support plate by the screw head be designed so that a very small number of Components becomes possible and thereby noise or adjustment inaccuracies can be avoided.
Die Verwendung einer separaten Scheibe als Auflageplatte vermeidet anderserseits vorteilhaft die aufwendige Bearbeitung der Unterseite des Schraubenkopfes zur Erzielung einer kugelsegmentförmigen Kontur. Sie vermeidet zudem, daß beim letzten Festziehen der Schraube eine unerwünschte Verstellung der Klappe erfolgen kann: es hat sich herausgestellt, daß die Reibung zwischen einer derartigen Scheibe und dem Halter größer sein kann als zwischen der Scheibe und dem Schraubenkopf, so daß die Schraube festgezogen werden kann und dabei ihre gewählte Winkelstellung am Halter beibehält.The use of a separate disc as a support plate on the other hand, advantageously avoids complex processing the bottom of the screw head to achieve a spherical segment Contour. It also avoids the last Tightening the screw an undesirable adjustment of the Flap can be done: it has been found that the friction between such a disc and the holder larger can be as between the washer and the screw head, so that the screw can be tightened while doing your chosen Maintains angular position on the holder.
Ein besonders großer Verstellbereich für die Klappe wird ermöglicht, wenn die Bohrung zumindest den doppelten Durchmesser aufweist wie die Schraube bzw. der Teil der Schraube, der sich durch diese Bohrung in dem Halter erstreckt. A particularly large adjustment range for the flap is made possible if the hole is at least twice the diameter has like the screw or part of the screw, which extends through this hole in the holder.
Vorteilhaft sind weitere Bauteile wie beispielsweise die üblicherweise mit Perlmutt ausgelegten Tastenflächen zur Betätigung der Klappe nicht unmittelbar an der Klappe befestigt, sondern am Halter oder anderen Bauteilen, von denen die Klappe durch das schwingungsdämpfende Zwischenstück getrennt ist. Dadurch werden Schrägstellungen, Verbiegungen und ähnliche Einwirkunge, die eine Fehlstellung der Klappe auf dem Tonlochrand bedingen können, vermieden. Das gleiche wie für die Tastenflächen gilt für Anschläge, die entweder zur Höhenbegrenzung des Halters bzw. Klappenarms dienen, an dem sie befestigt sind, oder die zur Kopplung und gemeinsamen Betätigung zweier Klappen in art eines "Mitnehmers" ausgestaltet sein können: auch bei diesen Anschlägen wird möglichst ein unmittelbarer Kontakt mit einer Klappe vermieden.Other components, such as those usually used, are advantageous Key surfaces designed with mother-of-pearl for actuation the flap is not attached directly to the flap, but on the holder or other components, of which the flap is separated by the vibration-damping intermediate piece. This will cause skewing, bending and the like Actions that misalign the flap on the tone hole edge can be avoided. The same as for the Key areas apply to stops that either limit the height the holder or flap arm on which they serve are attached, or for coupling and joint operation two flaps be designed in the manner of a "driver" can: even with these attacks, a direct Avoid contact with a flap.
Eine platz- und gewichtssparende Anordnung der Tastenfläche oder des Anschlags ist direkt auf dem Schraubenkopf möglich, wobei die Schraube zu ihrer Betätigung eine entsprechende Umfangsfläche aufweist, z.B. gerändelt zur werkzeuglosen Verschraubung, oder mit einer 6-Kant-Kontur oder ähnlichen Werkzeugflächen.A space and weight saving arrangement of the key surface or the stop is possible directly on the screw head, the screw being actuated accordingly Circumferential surface, e.g. knurled for tool-free screwing, or with a hexagon contour or similar tool surfaces.
Wenn die Tastenfläche oder der Anschlag exzentrisch neben dem Schraubenkopf angeordnet sein sollen, können sie vorteilhaft an der separaten, die Auflageplatte bildenden Scheibe befestigt sein. So läßt sich die Schraube lockern oder fester anziehen, ohne die Stellung der Tastenfläche oder des Anschlags zu verändern.If the button surface or the stop is eccentric next to the screw head should be arranged, they can be advantageous attached to the separate disk forming the support plate his. So the screw can be loosened or tightened, without the position of the button surface or the stop to change.
Über die reine Funktion des Klappenhalters hinaus kann der Halter verlängert sein, um die Tastenfläche aufzunehmen. Weiterhin kann ein derart verlängerter Halter die aus der Praxis bekannten Anschläge ausbilden, die gegen Puffer aus Filz oder anderen dämpfenden Materialien wie z.B. Schaumstoffen anschlagen können und die entweder zur Höhenbegrenzung für die Öffnungsbewegung der Klappe vorgesehen sind oder als Mitnehmer, wenn durch eine einzelne Taste mehrere Klappen gleichzeitig betätigt werden sollen und über ein entsprechendes Verbindungsgestänge miteinander verbunden sind.In addition to the pure function of the flap holder, the Holder can be extended to accommodate the button surface. Furthermore, such an extended holder can be used in practice train known attacks against buffers made of felt or other damping materials such as Apply foams can and either limit the height for the opening movement of the flap are provided or as Driver if several flaps by a single key should be operated simultaneously and via a corresponding Linkage rods are interconnected.
