Abstract
Description
la présente invention concerne un dispositif d'assemblage de deux parties consécutives d'un instrument de musique à vent, notamment en bois.the present invention relates to a device for assembling two consecutive parts of a wind musical instrument, in particular made of wood.
Traditionnellement un tel assemblage s'effectue par l'intermédiaire d'un tenon de l'une des parties, apte à s'engager dans une emboîture de l'autre partie, ledit tenon étant habillé d'une fine feuille de liège, assurant un emboîtement doux et étanche.Traditionally, such an assembly is carried out by means of a tenon of one of the parts, capable of engaging in a socket of the other part, said tenon being covered with a thin sheet of cork, ensuring a soft and waterproof interlocking.
L'application de la feuille de liège sur le tenon présente bon nombre d'inconvénients. En effet cette application est effectuée par collage d'une fine bande de liège de longueur et de largeur déterminées autour du tenon. Ensuite cette feuille est maintenue solidement pendant la prise de la colle à l'aide d'une ligature à spires multiples nécessitant pour sa pose de l'habileté et du soin, d'où une main d'oeuvre qualifiée et par conséquent onéreuse.The application of the cork sheet to the post has a number of drawbacks. Indeed, this application is carried out by gluing a thin strip of cork of determined length and width around the post. Then this sheet is held securely during the setting of the glue using a multi-turn ligature requiring for its installation skill and care, hence a skilled and therefore expensive workforce.
De plus, il est constaté lors d'un usage intensif de l'instrument, que le liège s'use relativement rapidement, ce qui tend à provoquer du jeu dans l'assemblage. L'instrument devient alors d'un maniement moins facile et ses caractéristiques musicales s'en trouvent modifiées. Il peut s'ensuivre également une torsion des clés, qui deviennent plus difficiles à actionner et peuvent aller jusqu'à se coincer.In addition, it is noted during intensive use of the instrument, that the cork wears relatively quickly, which tends to cause play in the assembly. The instrument then becomes less easy to handle and its musical characteristics are modified. It can also result in a twisting of the keys, which become more difficult to actuate and can go so far as to get stuck.
Mais il existe un inconvénient majeur qui découle de la hauteur des tenons, hauteur sur laquelle on ne peut pas intervenir sans diminuer en même temps la surface portante du liège et nuire par là même à sa bonne tenue sur ledit tenon.However, there is a major drawback which results from the height of the tenons, a height on which one cannot intervene without at the same time reducing the bearing surface of the cork and thereby adversely affecting its good behavior on said tenon.
C'est également pour cette même raison que la position de l'orifice de la première clé, immédiatement après la jonction des deux parties de l'instrument sera obligatoirement située à une distance minimale au moins égale à la hauteur du tenon précité.It is also for this same reason that the position of the orifice of the first key, immediately after the junction of the two parts of the instrument, must be located at a minimum distance at least equal to the height of the aforementioned stud.
Pratiquement cette hauteur, par exemple dans le cas d'une clarinette, est d'environ 18 mm.Practically this height, for example in the case of a clarinet, is approximately 18 mm.
Dans tous les cas d'instruments à vent, mais plus particulièrement dans les bois il a souvent été recherché d'intervenir sur la position de cet orifice afin qu'il soit situé à l'endroit acoustiquement le mieux placé, dit noeud de vibrations.In all cases of wind instruments, but more particularly in the woods, it has often been sought to intervene on the position of this orifice so that it is located at the acoustically best place, known as the vibration node.
Pour ce faire, il est connu de réaliser ces orifices dits de tonalité par perçage à la main et de les entailler délicatement pour améliorer la réponse et l'exactitude de l'intonation. On voit bien par là que les instruments à vent, mais plus particulièrement les bois sont de réalisation très difficile et que l'on a éprouvé le besoin et tenté de les perfectionner afin d'en faciliter le doigté.To do this, it is known to make these so-called tone orifices by drilling by hand and to cut them delicately to improve the response and the accuracy of the intonation. It is easy to see that the wind instruments, but more particularly the woods, are very difficult to make and that we have felt the need and tried to perfect them in order to facilitate fingering.
En ce qui concerne le hautbois, des modifications successives font qu'il craint moins qu'autrefois les tons chargés de dièses et de bémols mais néanmoins le son d'un hautbois ne sortira pas aussi aisément que celui d'une flûte, et certains traits dans le grave, entre si bémol et ré, offrent des difficultés considérables. Le hautbois est plus à son aise à partir du mi, mais on notera que même en jouant double piano le hautbois garde un timbre qui perce davantage que celui des autres bois et, dans certains cas, on n'obtiendra jamais avec un hautbois un double piano comparable à celui d'une flûte ou d'une clarinette.As far as the oboe is concerned, successive modifications mean that he is less afraid than before of tones loaded with sharps and flats but nevertheless the sound of an oboe will not come out as easily as that of a flute, and certain features in the bass, between B flat and D, offer considerable difficulties. The oboe is more comfortable from the middle, but note that even when playing double piano the oboe keeps a timbre which pierces more than that of other woods and, in some cases, you will never get a double oboe piano comparable to that of a flute or clarinet.
En ce qui concerne les diverses sonorités du hautbois, il faut préciser que bien que l'homogénéité de son timbre soit remarquable, le son change dans les aigus qui sont d'une justesse et d'une ampleur difficiles à obtenir, contrairement aux graves.Regarding the various sounds of the oboe, it should be noted that although the homogeneity of its timbre is remarkable, the sound changes in the treble which is of a precision and a magnitude difficult to obtain, unlike the bass.
En ce qui concerne la clarinette, celle-ci, par rapport au hautbois, se montre d'une extrême agilité et peut donner dans la plupart des nuances, du double piano au double forte.Regarding the clarinet, this one, compared to the oboe, is extremely agile and can give in most nuances, from double piano to double forte.
En ce qui concerne la clarinette en si bémol, pour ne parler que de celle-là plus généralement employée, au dessus du mi se trouvent quelques notes qui sonnent plus sourd et plus mat que les autres et que l'on nomme parfois le registre ingrat de l'instrument.Regarding the clarinet in B flat, to speak only of this one more generally used, above the E are some notes which sound duller and duller than the others and which are sometimes called the thankless register of the instrument.
La clarinette possède de grandes qualités musicales mais au prix d'un système de trous et de clés compliqué apte à fournir, en son fondamental, toute la gamme chromatique.The clarinet has great musical qualities but at the cost of a complicated system of holes and keys capable of providing, in its fundamental sound, the entire chromatic range.
La présente invention a pour but de remédier aux différents inconvénients précités, permettant une plus grande latitude dans le choix du positionnement de certains orifices de clés, jouant un rôle déterminant dans la justesse et la sonorité de l'instrument.The present invention aims to remedy the various aforementioned drawbacks, allowing greater latitude in the choice of the positioning of certain key holes, playing a decisive role in the accuracy and sound of the instrument.
A cet effet, l'invention concerne un dispositif d'assemblage de deux parties consécutives d'un instrument de musique à vent, notamment en bois, interposé à leur extrémité respective entre un tenon de l'une et une emboîture de l'autre, caractérisé en ce qu'il comprend au moins un premier ergot de verrouillage ménagé radialement sur la périphérie externe du tenon d'une partie et apte à coopérer avec au moins un second ergot complémentaire ménagé radialement sur la périphérie interne de l'emboîture de l'autre partie, le premier ergot s'ancrant derrière le second après un mouvement axial d'introduction du tenon dans l'emboîture, auquel succède un mouvement rotatif de l'une des parties de l'instrument par rapport à l'autre pour effectuer un assemblage du type baïonnette.To this end, the invention relates to a device for assembling two consecutive parts of a wind musical instrument, in particular made of wood, interposed at their respective ends between a tenon of one and a socket of the other, characterized in that it comprises at least a first locking lug formed radially on the external periphery of the lug of a part and capable of cooperating with at least one second complementary lug formed radially on the internal periphery of the socket of the other part, the first lug anchoring behind the second after an axial movement of introduction of the post in the socket, which follows a rotary movement of one of the parts of the instrument relative to the other to perform a bayonet type assembly.
De cette manière, on comprend aisément que les hauteurs de tenon, et par voie de conséquence de l'emboîture, peuvent être très fortement diminuées car non plus dépendantes des caractéristiques mécaniques de tenue du liège, qui est de ce fait purement et simplement supprimé.In this way, it is easily understood that the heights of the tenon, and consequently of the socket, can be very greatly reduced since they are no longer dependent on the mechanical characteristics of the cork, which is therefore purely and simply eliminated.
C'est ainsi que, par exemple dans les clarinettes, il s'est avéré qu'en raison de la résistance et la précision des parties en présence, en l'occurrence, tenon-emboîture, la hauteur de la jonction pouvait être ramenée de 18 mm à 10 mm environ, offrant ainsi une latitude supplémentaire de 8 mm dans la disposition idéale à rechercher, de certains orifices de l'instrument.Thus, for example in clarinets, it turned out that due to the resistance and the precision of the parts involved, in this case, tenon-socket, the height of the junction could be reduced from approximately 18 mm to 10 mm, thus offering an additional 8 mm latitude in the ideal arrangement to search for, of certain orifices of the instrument.
Outre cet avantage majeur, il est également à noter qu'une des conséquences secondaires de cette réduction de hauteur est le gain de matière procuré. En effet les corps de ces instruments sont réalisés dans des bois rigoureusement sélectionnés tels que l'ébène d'Afrique (Dalbergia, Melanoxylon) ou grenadille ou encore palissandre. Tous ces bois sont choisis en fonction de leurs propriétés acoustiques et esthétiques et coûtent par conséquent très cher. Un tel gain de matière aura donc forcément une incidence positive sur le prix de revient de l'instrument.In addition to this major advantage, it should also be noted that one of the secondary consequences of this reduction in height is the gain in material obtained. Indeed, the bodies of these instruments are made from rigorously selected woods such as African ebony (Dalbergia, Melanoxylon) or grenadilla or even rosewood. All these woods are chosen according to their acoustic and aesthetic properties and are therefore very expensive. Such material gain will therefore necessarily have a positive impact on the cost price of the instrument.

A titre d'exemple illustratif, la clarinette représentée sur les figures est constituée de manière connue d'un corps 1 comprenant une partie basse 2 et une partie haute 3. Ces parties 2 et 3, ainsi que les autres, sont aptes à être rendues solidaires par l'intermédiaire de moyens d'assemblage, constitués par un tenon 4 entouré de façon connue par une feuille de liège 5. Le tenon 4 vient s'engager dans une emboîture adaptée, référencée généralement par 6. Le corps 1 est constitué d'une manière générale par un cylindre creux réalisé dans un bois sélectionné pour ses qualités de rendu tonal, sa stabilité et sa robustesse, mais il peut également pour des modèles plus simples, d'étude par exemple, être réalisé en résine. Sur les parties 2 et 3 du corps 1 sont disposés des registres supérieur et inférieur, constitués de clés telles que 7 et d'orifices de tonalité tels que 8 et de tiges de liaison 9 reliant certaines clés entre elles. Une clarinette comporte généralement vingt quatre trous dont sept sont couverts avec les doigts et les autres avec les clés.As an illustrative example, the clarinet shown in the figures consists in a known manner of a body 1 comprising a
L'instrument se termine à sa partie inférieure par un pavillon évasé 10 assemblé à l'aide de moyens d'assemblage identiques à ceux précités.The instrument ends at its lower part with a
Il se termine à sa partie supérieure par un bec 11 muni d'une anche simple et disposé à la partie supérieure de la partie haute 3 du corps 1 par l'intermédiaire d'un barillet 12. Ces derniers éléments constitutifs de l'instrument sont également reliés entre eux de manière connue par les mêmes moyens d'assemblage précités.It ends at its upper part with a
A titre d'exemple illustratif, le dispositif d'assemblage, objet de la présente invention, trouve une application particulièrement avantageuse dans la liaison à effectuer entre la partie haute 3 du corps 1 et le barillet 12 d'une clarinette.As an illustrative example, the assembly device, object of the present invention, finds a particularly advantageous application in the connection to be made between the
On a représenté schématiquement sur les figures comparatives 7 et 8 les parties supérieures de l'instrument assemblées respectivement à l'aide du dispositif selon l'invention et de façon classique.There is shown schematically in Comparative Figures 7 and 8 the upper parts of the instrument assembled respectively using the device according to the invention and in a conventional manner.
Pour des raisons de clarté, on a adjoint la lettre A aux références destinées à désigner les parties équivalentes de l'instrument classique à assembler.For reasons of clarity, the letter A has been added to the references intended to designate the equivalent parts of the conventional instrument to be assembled.
En effet comme le montrent les figures comparatives 7 et 8, l'un des orifices de tonalité 13 ou 13A (connu) le plus proche du barillet 12 ou 12A est obturable par une clé 14 commandée par l'extrémité 15 d'un levier 16 (figures 1 et 2). L'axe transversal XX' passant par l'orifice 13A, comme le montre la figure 8, est à une distance du plan PP', correspondant au plan de joint du barillet 12A, égale à la hauteur "L" du tenon 4A du barillet 12A à laquelle s'ajoute une distance minimale "d" du fond de l'emboîture 6A jusqu'à l'axe XX'.Indeed, as shown in Comparative Figures 7 and 8, one of the tone orifices 13 or 13A (known) closest to the
Le but de l'invention est précisément de rapprocher l'orifice 13 du plan de joint PP' tout en le gardant à la même distance "d" existant entre un axe transversal YY' et le fond de l'emboîture 6, cette dernière devenant moins profonde selon une distance "1" égale à la longueur du tenon 4 correspondant.The object of the invention is precisely to bring the
Pratiquement et grâce aux moyens de l'invention qui vont être décrits ci-après, la hauteur "L" dont la valeur est classiquement de 18 mm peut être aisément réduite à 10 mm, d'où un gain, non négligeable en matière, de 8 mm.Practically and thanks to the means of the invention which will be described below, the height "L", the value of which is conventionally 18 mm, can easily be reduced to 10 mm, resulting in a significant gain in material, 8 mm.
Selon un exemple de réalisation pratique, la clarinette est assemblée par trois dispositifs adaptés haut 17, moyen 18 et bas 19 situés respectivement entre le barillet 12 et la partie haute 3, entre cette dernière et la partie basse 2 et entre cette dernière et le pavillon 10.According to an example of practical embodiment, the clarinet is assembled by three adapted devices high 17,
Chaque assemblage s'effectue par l'intermédiaire de deux douilles métalliques, préférentiellement en acier inoxydable, dont l'une 20 est rapportée et solidarisée dans l'emboîture 6 par une partie mâle 21, l'introduction de celle-ci s'effectuant jusqu'à ce qu'une collerette 22 vienne en appui sur le rebord annulaire 23 de la partie haute de l'instrument, et cela selon une position angulaire prédéterminée en fonction de trois ergots de verrouillage 24, 25, 26 ménagés radialement sur l'alésage interne 27 de la dite douille 21. Les ergots de verrouillage 24, 25, 26 sont espacés suivant des angles de 120° et différents les uns des autres en longueur ou du moins deux d'entre eux identiques et le troisième plus long.Each assembly is carried out by by means of two metal sockets, preferably made of stainless steel, one of which 20 is attached and secured in the
La seconde douille 28 est rapportée et solidarisée sur le tenon 4 du barillet 12 par une partie femelle 29, l'introduction de celle-ci s'effectuant jusqu'à rencontrer un rebord annulaire 30 du barillet 12 et cela selon une position angulaire prédéterminée en fonction de trois ergots complémentaires 31, 32, 33 ménagés également radialement sur la périphérie externe 34 de ladite douille 28.The
Le positionnement des ergots 31, 32, 33 de la douille 28 sont également espacés suivant des angles à 120°, mais de manière décalée par rapport aux ergots 24, 25, 26 de manière à permettre le passage des premiers entre les espaces délimités entre eux par les seconds, au cours d'un engagement axial du tenon 4A muni de la douille 28, dans l'emboîture 6 munie de la douille 20, auquel engagement axial succède un mouvement rotatif d'un angle donné en fonction d'un alignement à obtenir des parties à assembler et au cours duquel mouvement rotatif les ergots 31, 32, 33 s'ancrent derrière les ergots 24, 25, 26 pour effectuer un assemblage du type baïonnette.The positioning of the
Selon une caractéristique de l'invention les faces d'appui, par exemple des ergots 31, 32, 33 de la douille 28 avec les ergots 24, 25, 26 de la douille 21 constituent des portions de rampes hélicoïdales aptes à procurer un serrage axial des parties 3, 12 entre elles, après une rotation d'angle déterminé.According to a characteristic of the invention the bearing faces, for example lugs 31, 32, 33 of the
Selon une autre caractéristique de l'invention, l'un des ergots de verrouillage, 25 par exemple, d'une douille 21 est de dimensions plus grandes que les autres et coïncide au montage avec un espace correspondant ménagé entre deux ergots consécutifs 32, 33 de l'autre douille 28, de manière à constituer un détrompeur apte à assurer le bon alignement des parties 3 et 12 de l'instrument entre elles lors du montage.According to another characteristic of the invention, one of the locking lugs, for example, of a
Selon une autre caractéristique de l'invention, les douilles 20, 28 sont rapportées respectivement dans l'emboîture 6 et sur le tenon 4 par collage ou par emboîtement à force.According to another characteristic of the invention, the
Bien entendu, et cela sans sortir du cadre de la présente invention, les ergots 24, 25, 26 et 31, 32, 33 pourront être obtenus par usinage direct respectivement de l'emboîture 6 et du tenon 4.Of course, and this without departing from the scope of the present invention, the
