Description
L'invention consiste en un dispositif de tonalité de précision pour instruments k cordes au moyen d'un levier de serrage mobile fixé à un chevalet de l'instruent, une vis de réglage pour manoeuvrer le levier de serrage et, au levier de serrage, une rainure destinée à l'insertion dwune extrémité de corde munie d'un oeillet d'ancrage. The invention consists of a precision tone device for stringed instruments by means of a movable clamping lever fixed to an easel of the instructor, an adjusting screw for operating the clamping lever and, with the clamping lever, a groove intended for the insertion of an end of the cord provided with an anchoring eyelet.
Avec les dispositifs connus de tonalité de précision de cette nature, qui sont particulièrement destinés à etre fixés au chevalet d'instruments à archet tels que violons, violoncelles, contrebasses, la corde passe après sa sortie de la rainure sur une arrête vive qui, lors de la tension de la corde consécutive au maniement de la vis de reglage, s'y enfonce et l'abîme, de sorte que lVon peut facilement aboutir à une rupture de la corde. With known precision tone devices of this nature, which are particularly intended to be attached to the bridge of bowed instruments such as violins, cellos, double basses, the string passes after its exit from the groove on a sharp edge which, during of the tension of the rope following the handling of the adjusting screw, sinks into it and damages it, so that lVon can easily lead to a break in the rope.
Le but due l'invention est la suppression de cette lacune et l'élaboration d'un dispositif générique de tonalité de précision, évitant la rupture-de la corde à hauteur du levier de serrage et de sa rainure. The aim of the invention is to eliminate this shortcoming and develop a generic precision tone device, avoiding the breaking of the string up to the clamping lever and its groove.
L'invention atteint le but recherché par l'aménagement à l'issue de la rainure d'un -arrondi sur lequel la corde vient s'enrouler à sa sortie de la rainure. The invention achieves the aim sought by the arrangement at the end of the groove of a rounding on which the rope comes to be wound at its exit from the groove.
A titre d'explication supplémentire, nous donnons cidessous une description d'une forme préférentielle dtexécution de l'invention à laquelle nous joignons des croquis. Ceux-ci représentent
Croquis N I une vue de dessus d'un chevalet avec dispositif de tonalité de précision
Croquis NO 2 : une coupe longitudinale agrandie de la ligne 2-2 du croquis N0 I
Croquis NO 3 : un levier de serrage et,
Croquis NO 4 : une vue de dessus du levier de serrage du croquis NO 4 en direction de la flèche A.By way of additional explanation, we give below a description of a preferred embodiment of the invention to which we attach sketches. These represent
NI sketch a top view of an easel with precision tone device
Sketch NO 2: an enlarged longitudinal section of line 2-2 of sketch N0 I
Sketch NO 3: a clamping lever and,
Sketch NO 4: a top view of the clamping lever of sketch NO 4 in the direction of arrow A.
Le croquis NO I représente un chevalet 1 fixé de façon habituelle sur un instrument à archet(pwe. violon, violoncelle, contrebasse) Le chevalet 1 sert au maintien d'une des extrémités des cordes, dont l'autre extrémité est racco-rdée aux chevilles de l'instrument à archet. Pour accorder avec précision les diverses cordes, on intègre au chevalet I quatre -un par cordedispositifs de tonalité de précision 2, dont un modelé est représenté latéralement par le croquis N 2. The sketch NO I represents a bridge 1 fixed in the usual way on a bowed instrument (pwe. Violin, cello, double bass) Bridge 1 is used to hold one end of the strings, the other end of which is racco-rdée to pegs of the bowed instrument. To accurately tune the various strings, four-one bridge I is integrated with precision tone strings 2, one of which is modeled laterally by sketch N 2.
Le dispositif de tonalité de précision comprend comme élément essentiel, autour d'un axe passant en biais dans le chevalet 1, un levier de serrage 4 de forme coudée. Une vis de règlage 6 fixée au chevalet 1 au moyen d'une bague filetée 5 accroche la branche longue du levier de serrage 4. Sur la branche courte du levier de serrage 4, voir notamment croquis N9 3 et NO 4, est aménagée une rainure 7. Dans cette rainure se pose l'extrémité habituellement pourvue d'un épaississement 8, d'une corde 9. En général, la corde est munie à son extrémité d'un élément d'ancrage, p.e. un petit oeillet, afin d'éviter que la corde, lorsqu'elle est tendue, s'échappe de la rainure 7.La corde, fixée à la cheville de l'instrument, est accordée avec précision par le maniement de la vis de règlage 6 faisant se déplacer le levier de serrage 4. Le trajet du levier de serrage 4 est représenté au croquis NO 2 par une ligne formée de traits et de points. The precision tone device comprises as an essential element, around an axis passing at an angle in the easel 1, a clamping lever 4 of angled shape. A adjusting screw 6 fixed to the bridge 1 by means of a threaded ring 5 hooks the long branch of the clamping lever 4. On the short branch of the clamping lever 4, see in particular sketch N9 3 and NO 4, a groove is arranged 7. In this groove is posed the end usually provided with a thickening 8, of a cord 9. In general, the cord is provided at its end with an anchoring element, eg a small eyelet, in order to prevent the rope, when it is stretched, from escaping from the groove 7. The rope, fixed to the ankle of the instrument, is precisely tuned by the use of the adjusting screw 6 causing the lever to move tightening 4. The path of the tightening lever 4 is shown in sketch NO 2 by a line formed by lines and dots.
Comme cela ressort particulièrement des croquis NO 3 et NO 4, la rainure 7 présente à son issue 12, faisant face au côté de la rainure supportant l'élément d'ancrage 11, une saillie 13 en forme de nez dont la partie supérieure constitue un arrondi 14.A sa sortie de la rainure 7 (croquis NO 2), la corde 9 repose sur l'arrondi. Le fond de la rainure 7 restant, comme le montre le croquis NO 3, continu et lisse en passant à l'arrondi 14, et celui-ci étant incurvé et modelé en conséquence, il 'y a pas d'arête vive risquant, lors de l'évolution du levier de serrage 4 le long de la ligne de traits et de points représen tée au croquis NO 2, de s'enfoncer dans la corde et de l'abimer. As is particularly apparent from sketches NO 3 and NO 4, the groove 7 has at its end 12, facing the side of the groove supporting the anchoring element 11, a projection 13 in the form of a nose, the upper part of which constitutes a round 14.At its exit from the groove 7 (sketch NO 2), the cord 9 rests on the round. The bottom of the groove 7 remaining, as shown in the sketch NO 3, continuous and smooth passing to the round 14, and the latter being curved and shaped accordingly, there is no sharp edge risking, during of the evolution of the clamping lever 4 along the line of lines and points represented in the sketch NO 2, of sinking into the rope and damaging it.
Done, quelle que soit la position du levier de serrage 4, la corde repose toujours en arrondi sur la saillie 13 de sorte qu'elle est protégée contre la rupture. Done, whatever the position of the clamping lever 4, the rope always rests rounded on the projection 13 so that it is protected against breakage.
En outre, la saillie 13 en forme de nez aménagée devant l'issue de la rainure 7, comporte l'avantage de prolonger le bras du levier de serrage 4 servant au règlage de précision de la tonalité par rapport à son axe de fixation 3. Une éxécution différente de l'invention permet d'éliminer cette saillie. Dans ce cas, l'arête se trouvant au débouché de la rainure entre les deux butées 15 et 16 (croquis NO 4) délimitant celle-ci doit elle-meme être arrondie, auquel cas l'arrondi peut s'étendre en partie à l'intérieur de la rainure 7. In addition, the nose-shaped projection 13 arranged in front of the end of the groove 7 has the advantage of extending the arm of the clamping lever 4 used for adjusting the precision of the tone relative to its fixing axis 3. A different embodiment of the invention makes it possible to eliminate this projection. In this case, the edge located at the outlet of the groove between the two stops 15 and 16 (sketch NO 4) delimiting the latter must itself be rounded, in which case the rounding may extend in part to the inside the groove 7.
Il s'est avéré que pour éviter une rupture de corde, l'arrondi doit présenter un rayon de courbure d'au moins 1,2 mm. It has been found that to avoid breaking the rope, the rounding must have a radius of curvature of at least 1.2 mm.
De préférence, ce rayon de -courbure se situera entre 1,5 et 2,5 mm. 4 cet égard, le rayon de courbure dépend de l'épaisseur de la corde et de l'instrument correspondant. Pour les instruments volumineux (contrebasses) et les épaisseurs plus importante de cordes, on augmentera en concomitance le rayon de courbure de l'arrondi 14. Preferably, this radius of curvature will be between 1.5 and 2.5 mm. In this regard, the radius of curvature depends on the thickness of the cord and the corresponding instrument. For voluminous instruments (double basses) and larger thicknesses of strings, the radius of curvature of the rounding 14 will be increased at the same time.
