L'invention concerne le domaine des pièces d'horlogerie à sonnerie ou à musique, telles que montres à répétition minutes, montres avec fonction de réveil, boîtes à musique, et similaires.The invention relates to the field of striking or musical timepieces, such as minute repeater watches, watches with alarm clock, music boxes, and the like.

Arrière-plan de l'inventionInvention background

Dans les pièces d'horlogerie à sonnerie ou à mélodie, notamment les montres à répétition minutes, les améliorations vibro-acoustiques portent essentiellement sur des éléments de l'habillage permettant d'augmenter le niveau acoustique de la sonnerie, mais aussi sur les éléments de régulation, pour limiter le bruit du mécanisme lors du déclenchement de sonnerie et ainsi augmenter l'émergence du son produit par la sonnerie, par augmentation du ratio entre le niveau acoustique de la sonnerie et celui du bruit du mécanisme.In striking or melody timepieces, in particular minute repeater watches, vibro-acoustic improvements relate mainly to elements of the casing making it possible to increase the acoustic level of the striking, but also to the elements of regulation, to limit the noise of the mechanism when the ringing is triggered and thus increase the emergence of the sound produced by the ringing, by increasing the ratio between the acoustic level of the ringing and that of the noise of the mechanism.

Au niveau de l'habillage, des glaces rayonnantes ou des lunettes désolidarisées permettent d'optimiser la réponse vibratoire de l'habillage sur une large bande fréquentielle et d'accroître ainsi le niveau acoustique engendré par son rayonnement. Pour que les éléments puissent avoir un fort pouvoir rayonnant sur une large bande fréquentielle, il est nécessaire que ces derniers soient susceptibles de vibrer librement et ceci indépendamment de la fréquence d'excitation qu'ils subissent.At the level of the covering, radiant glass or separate glasses make it possible to optimize the vibratory response of the covering over a wide frequency band and thus to increase the acoustic level generated by its radiation. So that the elements can have a strong radiating power on a broad frequency band, it is necessary that these last are likely to vibrate freely and this independently of the excitation frequency which they undergo.

L'amplitude vibratoire de l'habillage, quant à elle, dépend d'un bon accordage fréquentiel entre la fréquence d'excitation et celles de l'habillage mais aussi du bon transfert solidien entre l'élément générateur de vibration, tel qu'un timbre ou similaire, et un élément rayonnant tel qu'un ensemble lunette-glace ou un fond. Il faut donc que les vibrations se propagent aisément sans être atténuées par des éléments intermédiaires entre l'élément générateur de vibrations et l'élément destiné à rayonner, ni par des joints nécessaires à l'étanchéité de la pièce, qui peuvent empêcher les éléments rayonnants de vibrer librement.The vibrational amplitude of the covering, for its part, depends on a good frequency tuning between the excitation frequency and those of the covering but also on the good solidien transfer between the vibration generating element, such as a stamp or similar, and a radiating element such as a lens-glass assembly or a background. It is therefore necessary that the vibrations propagate easily without being attenuated by intermediate elements between the vibration generating element and the element intended to radiate, nor by seals necessary for sealing the part, which can prevent the radiating elements. to vibrate freely.

Cette pièce élastique annulaire présente au plus quatre segments annulaires, présentant chacun vu en coupe une forme rectiligne. Le bord extérieur de la pièce annulaire élastique est destiné à être serré entre une lunette et une carrure de la pièce d'horlogerie à l'aide d'un joint d'étanchéité : La partie de la pièce élastique annulaire qui ne se trouve pas sous la glace est logée entièrement sous la lunette.The document CH 698 742 B1 in the name of RICHEMONT describes a device for connecting a bell to the crystal of a timepiece. The stamp is secured to a heel fixed by screws on part of the movement.

Description détaillée des modes de réalisation préférésDetailed description of preferred embodiments

L'invention se propose de réaliser une pièce d'horlogerie comportant des moyens d'émission sonore enfermés dans une boîte, et des moyens de rayonnement de la vibration sonore vers l'utilisateur, utilisant certains éléments de l'habillage de la pièce d'horlogerie, en restreignant au maximum les fortes atténuations vibratoires provoquées usuellement par les joints d'étanchéité de l'habillage, afin de laisser vibrer librement ceux des éléments de l'habillage qui sont destinés à rayonner, appelés ici l'élément rayonnant.The invention proposes to produce a timepiece comprising sound emission means enclosed in a box, and means for radiating the sound vibration towards the user, using certain elements of the covering of the piece. watchmaking, by limiting as much as possible the strong vibration attenuations usually caused by the seals of the covering, in order to allow those elements of the covering which are intended to radiate to vibrate freely, here called the radiating element.

Pour que le système vibro-acoustique constitué par l'élément générateur de vibration et l'élément rayonnant soit efficace, il est important que l'élément rayonnant puisse vibrer librement selon ses modes propres, lesquels sont définis principalement par son système de fixation. Pour éviter que les vibrations ne se propagent au reste de l'habillage, il est important que le contact entre l'élément rayonnant et la partie la plus rigide de la boîte, notamment une carrure, soit minimal. Cependant ce genre d'habillage va à l'encontre d'une construction étanche. L'invention optimise le transfert vibratoire, tout en garantissant l'étanchéité de la pièce d'horlogerie.In order for the vibro-acoustic system constituted by the vibration generating element and the radiating element to be effective, it is important that the radiating element can vibrate freely according to its own modes, which are mainly defined by its fixing system. To prevent vibrations from propagating to the rest of the covering, it is important that the contact between the radiating element and the most rigid part of the box, in particular a middle part, is minimal. However, this type of covering goes against a waterproof construction. The invention optimizes vibration transfer, while guaranteeing the watertightness of the timepiece.

L'invention est décrite et illustrée dans le cas particulier et non limitatif d'une montre à sonnerie, elle est applicable directement à une montre musicale, à une boîte à musique, ou autre pièce d'horlogerie similaire.The invention is described and illustrated in the particular and non-limiting case of a striking watch, it is directly applicable to a musical watch, a music box, or other similar timepiece.

Dans le cas d'une montre, l'ensemble constitué par la carrure et le fond est l'élément le plus rigide, et est en contact direct avec l'utilisateur. L'élément rayonnant est, en général, de préférence situé à l'opposé du fond, et comporte avantageusement au moins la lunette ou la glace.In the case of a watch, the assembly constituted by the middle part and the back is the most rigid element, and is in direct contact with the user. The radiating element is, in general, preferably located opposite the bottom, and advantageously comprises at least the telescope or the glass.

L'invention est décrite pour une boîte de montre 100 comportant une structure rigide comportant elle-même une carrure. Sur cette carrure est fixée une lunette qui porte classiquement une glace. L'homme du métier transposera sans problème cette exécution à une boîte à musique ou similaire.The invention is described for a watch case 100 comprising a rigid structure itself comprising a middle part. On this middle part is fixed a bezel which conventionally carries a mirror. Those skilled in the art will easily transpose this performance to a music box or the like.

Ainsi l'invention concerne une boîte de montre 100 comportant une structure 1 rigide, et au moins un composant résonateur 2. Cet au moins un composant résonateur 2 est agencé pour être assemblé de façon rigide, directement ou indirectement, à la structure 1.Thus, the invention relates to a watch case 100 comprising a rigid structure 1, and at least one resonator component 2. This at least one resonator component 2 is designed to be rigidly assembled, directly or indirectly, to the structure 1.

De préférence, le composant résonateur 2, même s'il comporte une membrane ou un tel composant destiné à vibrer, comporte au moins une partie de rigidité proche de celle de la structure 1, et la fixation est réalisée au niveau de ces parties rigides du composant résonateur 2 et de la structure 1.Preferably, the resonator component 2, even if it comprises a membrane or such a component intended to vibrate, comprises at least part of rigidity close to that of structure 1, and the fixing is carried out at the level of these rigid parts of the resonator component 2 and of structure 1.

Ce composant résonateur 2 définit avec la structure 1, quand ils sont assemblés l'un à l'autre dans une position assemblée de service, une chambre 4 qui renferme au moins un élément d'étanchéité 3 entre la structure 1 et le composant résonateur 2. Cette chambre 4 fait le tour de la boîte de montre 100. Elle a une hauteur correspondant à une valeur de jeu J suffisante pour autoriser, sans l'entraver, la vibration à pleine amplitude du composant résonateur 2 par rapport à la structure 1.This resonator component 2 defines with the structure 1, when they are assembled to each other in an assembled service position, a chamber 4 which contains at least one sealing element 3 between the structure 1 and the resonator component 2 This chamber 4 goes around the watch case 100. It has a height corresponding to a play value J sufficient to allow, without impeding it, the vibration at full amplitude of the resonator component 2 relative to the structure 1.

La structure 1 et/ou le composant résonateur 2 comporte une gorge 51, 52, qui est agencée pour recevoir un joint 31, 32, que comporte cet élément d'étanchéité 3, et pour interdire l'extraction de l'élément d'étanchéité 3 de la chambre 4 dans la position assemblée.The structure 1 and / or the resonator component 2 comprises a groove 51, 52, which is arranged to receive a seal 31, 32, which this sealing element 3 comprises, and to prevent the extraction of the sealing element 3 of chamber 4 in the assembled position.

Cet élément d'étanchéité 3 doit obéir à une problématique a priori contradictoire : ne pas constituer d'entrave aux vibrations du composant résonateur 2, et assurer l'étanchéité classique d'une montre sous quelques milliers d'hectopascal, face à l'eau ainsi qu'aux poussières et similaires. Dans une réalisation avantageuse, l'élément d'étanchéité 3 comporte au moins un joint 31, 32, dont la forme déformée sous une telle pression externe est différente de sa forme au repos sous pression atmosphérique normale. De préférence, ce joint comporte au moins une lèvre 310 plus fine que le corps de joint 320 plus massif, lequel est utilisé pour le maintien de ce joint dans une gorge ou un logement, laquelle lèvre fine 310 est en appui sur une surface plane 81, 82, sur laquelle elle est d'autant plus plaquée que la pression extérieure est grande.This sealing element 3 must obey an a priori contradictory problem: not to constitute an obstacle to the vibrations of the resonator component 2, and to ensure the conventional sealing of a watch under a few thousand hectopascals, facing the water. as well as dust and the like. In an advantageous embodiment, the sealing element 3 comprises at least one seal 31, 32, the shape of which is deformed under such external pressure is different from its shape at rest under normal atmospheric pressure. Preferably, this seal has at least one lip 310 thinner than the more solid joint body 320, which is used to hold this seal in a groove or a housing, which thin lip 310 is supported on a flat surface 81 , 82, on which it is all the more pressed the greater the external pressure.

De façon propre à l'invention, soit la structure 1 et/ou le composant résonateur 2 soit l'élément d'étanchéité 3 comporte au moins un relief saillant 61, 62, 63, qui est rigide, et qui est agencé pour, dans la position assemblée, exercer un effort de compression sur au moins un joint 31, 32, face à une zone médiane de la gorge 51, 52, qui reçoit ce joint 31, 32. Ainsi, lors de l'assemblage du composant résonateur 2 sur la structure 1, l'élément d'étanchéité 3 est comprimé entre eux, et chaque relief saillant comprime un joint dans une gorge, rendant la boîte 100 étanche. Un tel montage d'élément d'étanchéité n'est pas usuel, car les gorges servent usuellement de maintien à une partie d'un joint dont une surface opposée à la gorge vient en appui sur une surface antagoniste lisse; de plus on éviter généralement de risquer de blesser un joint par un appui sur un saillant.Specifically to the invention, either the structure 1 and / or the resonator component 2 or the sealing element 3 comprises at least one projecting relief 61, 62, 63, which is rigid, and which is arranged for, in the assembled position, exert a compressive force on at least one joint 31, 32, facing a central region of the groove 51, 52, which receives this joint 31, 32. Thus, during the assembly of the resonator component 2 on the structure 1, the sealing element 3 is compressed between them, and each projecting relief compresses a seal in a groove, making the box 100 waterproof. Such a sealing element mounting is not usual, because the grooves usually serve to hold part of a joint whose surface opposite the groove support on a smooth antagonistic surface; moreover, one generally avoids risking injuring a joint by pressing on a projection.

Aussi, dans le cadre de l'invention, choisit-on de préférence un joint en silicone ou similaire, avec une très faible dureté Shore, de préférence inférieure ou égale à 20 Shore A.Also, in the context of the invention, we preferably choose a silicone seal or similar, with a very low Shore hardness, preferably less than or equal to 20 Shore A.

Ainsi, l'élément d'étanchéité 3 comporte avantageusement au moins un joint 31, 32, de dureté inférieure ou égale à 20 Shore A.Thus, the sealing element 3 advantageously comprises at least one seal 31, 32, of hardness less than or equal to 20 Shore A.

Plus particulièrement, chaque joint 31, 32 que comporte l'élément d'étanchéité 3 a une dureté inférieure ou égale à 20 Shore A.More particularly, each seal 31, 32 that comprises the sealing element 3 has a hardness less than or equal to 20 Shore A.

Le système de fixation mécanique entre la structure 1 et le composant résonateur 2, notamment par au moins une patte 7, laisse un jeu axial J entre la structure 1 et le composant résonateur 2. La perte d'étanchéité résultant de ce jeu J nécessaire à la vibration optimale est ainsi compensée par cet élément d'étanchéité 3 particulier, propre à l'invention.The mechanical fixing system between the structure 1 and the resonator component 2, in particular by at least one tab 7, leaves an axial clearance J between the structure 1 and the resonator component 2. The loss of tightness resulting from this clearance J necessary for the optimal vibration is thus compensated by this particular sealing element 3, specific to the invention.

Dans une réalisation particulière, par exemple tel que visible sur les figures 2, 7 ou 21, la boîte de montre 100 comporte plusieurs éléments d'étanchéité 3 intérieurs les uns aux autres délimitant au moins un volume intermédiaire étanche.In a particular embodiment, for example as visible on the figures 2 , 7 or 21 , the watch case 100 includes several internal sealing elements 3 to each other delimiting at least one sealed intermediate volume.

Naturellement le relief saillant 61, 62, 63, est dépourvu d'arête vive, et comporte de préférence un profil rayonné pour éviter de blesser le joint. L'élément d'étanchéité 3, une fois monté, ne subit plus de déplacement à proprement parler; sa fonction est d'assurer l'étanchéité de l'intérieur de la boîte 100, en particulier quand le composant résonateur 2 vibre, cette vibration se faisant avec une amplitude maximale bien déterminée. Chaque joint 31, 32, que comporte l'élément d'étanchéité 3, peut ainsi tolérer cette vibration et assurer une étanchéité parfaite à tout moment.Naturally the projecting relief 61, 62, 63, has no sharp edge, and preferably comprises a radiated profile to avoid injuring the joint. The sealing element 3, once mounted, no longer undergoes actual displacement; its function is to seal the interior of the box 100, in particular when the resonator component 2 vibrates, this vibration being carried out with a well-determined maximum amplitude. Each seal 31, 32, which comprises the sealing element 3, can thus tolerate this vibration and ensure perfect sealing at all times.

Le relief saillant 61, 62, peut venir de fabrication avec la structure 1 ou le composant résonateur 2, mais il peut aussi être rapporté sur l'un d'eux. Selon l'invention, le relief saillant 61, 62, 63 est rigide ou au moins dix fois moins déformable que le joint concerné, à égalité de compression.The protruding relief 61, 62 can come from manufacturing with the structure 1 or the resonator component 2, but it can also be attached to one of them. According to the invention, the projecting relief 61, 62, 63 is rigid or at least ten times less deformable than the joint concerned, with equal compression.

Dans une mise en œuvre préférée, et tel que visible sur les figures, le composant résonateur 2 tend à vibrer selon un axe Z sensiblement perpendiculaire aux surfaces d'appui du ou des joints 31, 32, face à la ou les gorges 51, 52, dans un mode de résonance dit « piston ». Chaque joint 31, 32, est donc sollicité uniquement selon cette direction, et avec une amplitude très restreinte, inférieure à 0.10 mm et plus souvent de l'ordre du centième de millimètre.In a preferred implementation, and as visible in the figures, the resonator component 2 tends to vibrate along an axis Z substantially perpendicular to the bearing surfaces of the joint (s) 31, 32, facing the groove (s) 51, 52 , in a resonance mode called "piston". Each joint 31, 32, is therefore stressed only in this direction, and with a very limited amplitude, less than 0.10 mm and more often of the order of a hundredth of a millimeter.

Dans une première variante, selon l'invention, tel que visible sur la figure 1, l'élément d'étanchéité 3 comporte un joint 31, 32, unique, la structure 1 ou respectivement le composant résonateur 2 comporte une gorge 51, 52, et le composant résonateur 2, ou respectivement la structure 1, comporte un relief saillant 62, 61. Naturellement, cette première variante peut être extrapolée à une variante dont un exemple est illustré à la figure 7, où l'élément d'étanchéité 3 comporte plusieurs joints 31, 32, indépendants l'un de l'autre, et intérieur l'un à l'autre, c'est-à-dire qu'ils ont des rayons différents, et la structure 1 ou le composant résonateur 2 comportent de telles gorges 51, 52, et des reliefs saillants 62, 61, antagonistes, de façon à ce que chacun de ces joints soit comprimé par un relief saillant vers le fond de sa gorge de réception respective, lors de l'assemblage relatif de la structure 1 ou le composant résonateur 2.In a first variant, according to the invention, as visible on the figure 1 , the sealing element 3 comprises a single joint 31, 32, the structure 1 or respectively the resonator component 2 comprises a groove 51, 52, and the resonator component 2, or respectively the structure 1, has a protruding relief 62 , 61. Naturally, this first variant can be extrapolated to a variant, an example of which is illustrated in figure 7 , where the sealing element 3 comprises several seals 31, 32, independent of each other, and interior to one another, that is to say that they have different radii, and the structure 1 or the resonator component 2 have such grooves 51, 52, and protruding reliefs 62, 61, antagonistic, so that each of these joints is compressed by a protruding relief towards the bottom of its receiving groove respective, during the relative assembly of the structure 1 or the resonator component 2.

Dans une deuxième variante selon l'invention, tel que visible sur la figure 2, la structure 1 comporte une première gorge 51 et le composant résonateur 2 comporte une deuxième gorge 52 à distance de la première gorge 51. L'élément d'étanchéité 3 comporte, solidaires entre eux, au moins un premier joint 31 et un deuxième joint 32 distants l'un de l'autre et reliés l'un à l'autre par une membrane étanche 33 s'étendant entre la première gorge 51 et la deuxième gorge 52,. De façon similaire à précédemment, la structure 1 comporte un premier relief saillant 61 agencé pour coopérer avec le deuxième joint 32 en face de la deuxième gorge 52, et le composant résonateur 2 comporte un deuxième relief saillant 62 agencé pour coopérer avec le premier joint 31 en face de la première gorge 51. L'étanchéité est alors triple: effectuée par chacun des joints 31, 32 de façon antagoniste, et par la membrane 33.In a second variant according to the invention, as visible on the figure 2 , the structure 1 comprises a first groove 51 and the resonator component 2 comprises a second groove 52 at a distance from the first groove 51. The sealing element 3 comprises, integral with each other, at least a first seal 31 and a second seal 32 distant from each other and connected to each other by a waterproof membrane 33 extending between the first groove 51 and the second groove 52,. Similarly to previously, the structure 1 comprises a first projecting relief 61 arranged to cooperate with the second seal 32 opposite the second groove 52, and the resonator component 2 comprises a second projecting relief 62 arranged to cooperate with the first seal 31 opposite the first groove 51. The tightness is then threefold: effected by each of the joints 31, 32 in an antagonistic manner, and by the membrane 33.

Dans une troisième variante selon l'invention, tel que visible sur la figure 3, la structure 1 comporte une première gorge 51, et le composant résonateur 2 comporte une deuxième gorge 52 sensiblement en face de la première gorge 51. L'élément d'étanchéité 3 comporte au moins un premier joint 31 et un deuxième joint 32 distants l'un de l'autre et reliés l'un à l'autre par un troisième relief saillant rigide 63. Et ce troisième relief saillant rigide 63 est agencé pour coopérer à la fois avec le premier joint 31 en face de la première gorge 51 et avec le deuxième joint 32 en face de la deuxième gorge 52. L'élément d'étanchéité 3 peut être réalisé par surmoulage d'un tel troisième relief saillant rigide 63, par exemple en matière plastique dure, dans un enrobage de silicone constituant le premier joint 31 et le deuxième joint 32. Le troisième relief saillant rigide 63 peut consister en un anneau rigide maintenu et pris en sandwich par des joints 31 et 32 en silicone, moulés et déposés dans les gorges 51 et 52. Cet anneau ne touche ni la structure 1, ni le composant résonateur 2, pour éviter tout contact rigide. Cet anneau peut aussi avoir la forme d'un tronc de cône, incliné par rapport à l'axe axial Z de la boîte 100.In a third variant according to the invention, as visible on the figure 3 , the structure 1 comprises a first groove 51, and the resonator component 2 comprises a second groove 52 substantially opposite the first groove 51. The sealing element 3 comprises at least a first seal 31 and a second seal 32 distant l 'from one another and connected to each other by a third rigid protruding relief 63. And this third rigid protruding relief 63 is arranged to cooperate both with the first seal 31 opposite the first groove 51 and with the second seal 32 opposite the second groove 52. The sealing element 3 can be produced by overmolding of such a third rigid protruding relief 63, for example of hard plastic material, in a silicone coating constituting the first seal 31 and the second seal 32. The third rigid protruding relief 63 may consist of a rigid ring maintained and taken sandwich by silicone seals 31 and 32, molded and deposited in the grooves 51 and 52. This ring does not touch the structure 1 or the resonator component 2, to avoid any rigid contact. This ring can also have the shape of a truncated cone, inclined relative to the axial axis Z of the box 100.

Les figures illustrent une variante préférée où chaque relief saillant 62, 61 est une nervure fermée, dont la forme suit celle de la boîte 100.The figures illustrate a preferred variant where each projecting relief 62, 61 is a closed rib, the shape of which follows that of the box 100.

Dans ces variantes, le relief saillant 62, 61 est solidaire de la structure 1 ou respectivement le composant résonateur 2, et est soit soudé ou brasé ou usiné directement avec l'élément concerné.In these variants, the raised relief 62, 61 is integral with the structure 1 or respectively the resonator component 2, and is either welded or brazed or machined directly with the element concerned.

On notera, encore, que l'élément d'étanchéité 3, ou l'un des joints 31, 32, qu'il comporte, n'est pas nécessairement un élément rapporté, et peut être en silicone moulé directement à l'intérieur de la gorge adéquate.It will also be noted that the sealing element 3, or one of the seals 31, 32, which it comprises, is not necessarily an added element, and may be made of silicone molded directly inside adequate throat.

Les figures 4 et 5 illustrent un autre mode de fabrication d'une telle boîte 100, où la structure 1 ou le composant résonateur 2 comporte une surface plane 81, 82, et où le composant antagoniste comporte, maintenu dans une gorge 52, 51, la partie de plus forte section 320 d'un joint sensiblement conique qui s'amincit graduellement vers une lèvre 310 de plus faible section, qui coopère avec cette surface plane antagoniste 81, 82. Là aussi, ce joint est presque statique et a pour fonction de s'opposer aux entrées d'eau et d'impuretés, en laissant vibrer le plus librement possible le composant résonateur 2. Et, de préférence, ce joint est aussi en silicone ou similaire, avec une très faible dureté Shore, de préférence inférieure ou égale à 20 Shore A.The Figures 4 and 5 illustrate another method of manufacturing such a box 100, where the structure 1 or the resonator component 2 comprises a flat surface 81, 82, and where the opposing component comprises, held in a groove 52, 51, the stronger part section 320 of a substantially conical seal which gradually tapers towards a lip 310 of smaller section, which cooperates with this opposing planar surface 81, 82. Again, this seal is almost static and has the function of opposing the entries of water and impurities, leaving the resonator component 2 to vibrate as freely as possible. And, preferably, this seal is also made of silicone or similar, with a very low Shore hardness, preferably less than or equal to 20 Shore AT.

La liaison mécanique entre la structure 1 et le composant résonateur 2 peut être réalisée de différentes façons. De préférence cette liaison est sensiblement ponctuelle, de façon à ce que la plus grande partie du composant résonateur 2 puisse vibrer le plus librement possible entre deux liaisons rigides. Les figures 5 à 16 illustrent, de façon non limitative, une liaison par pattes, solidaires de la structure 1, et/ou du composant résonateur 2. Ainsi, dans une variante particulière, la structure 1ou le composant résonateur 2 comporte au moins une patte 7 pour sa fixation rigide et directe au composant résonateur 2 ou respectivement à la structure 1. Plus particulièrement, la liaison mécanique réalisée par la fixation rigide entre le composant résonateur 2 et la structure 1 comporte trois pattes 7.The mechanical connection between the structure 1 and the resonator component 2 can be achieved in different ways. Preferably this connection is substantially punctual, so that most of the resonator component 2 can vibrate as freely as possible between two rigid connections. The figures 5 to 16 illustrate, without limitation, a connection by lugs, integral with the structure 1, and / or the resonator component 2. Thus, in a particular variant, the structure 1or the resonator component 2 comprises at least one lug 7 for its rigid fixing and direct to the resonator component 2 or respectively to the structure 1. More particularly, the mechanical connection produced by the rigid attachment between the resonator component 2 and the structure 1 has three tabs 7.

Ces pattes 7 peuvent être vissées pour permettre un démontage, ou encore chassées, soudées, brasées, ou autre. La figure 17 illustre une variante particulière où une patte 7 est fermement maintenue par un ressort 70 autorisant un démontage facile. Naturellement il y a alors un moyen de limitation de course entre la structure 1 et le composant résonateur 2, par une vis ou similaire. Les figures 8 à 11 illustrent différentes variantes de pattes 7, plus ou moins rigides, ou au contraire élastiques.These tabs 7 can be screwed to allow disassembly, or even driven, welded, brazed, or other. The figure 17 illustrates a particular variant where a tab 7 is firmly held by a spring 70 allowing easy disassembly. Naturally, there is then a means of limiting the travel between the structure 1 and the resonator component 2, by a screw or the like. The figures 8 to 11 illustrate different variants of legs 7, more or less rigid, or on the contrary elastic.

La figure 5 montre un timbre 302 fixé à la carrure 1, percuté par un marteau 301, tandis que les figures 15 à 21 montrent un tel timbre monté solidaire de la lunette 2: lors de l'activation de cet élément générateur de vibration, par un marteau, un tambour à picots ou autre, les vibrations se propagent directement à l'ensemble lunette-glace. La figure 21 illustre un cas particulier où la boîte 100 comporte trois pattes en or, de largeur est égale à 3.8 mm, de hauteur est égale à 2.9 mm et d'épaisseur égale à 0.6 mm. Dans cette exécution, la lunette 2 porte un timbre 302, visible à travers la glace 9.The figure 5 shows a stamp 302 fixed to the middle part 1, struck by a hammer 301, while the Figures 15 to 21 show such a stamp mounted integral with the telescope 2: upon activation of this vibration generating element, by a hammer, a spiked drum or the like, the vibrations propagate directly to the telescope-glass assembly. The figure 21 illustrates a particular case where the box 100 has three gold tabs, of width is equal to 3.8 mm, of height is equal to 2.9 mm and of thickness equal to 0.6 mm. In this embodiment, the telescope 2 carries a stamp 302, visible through the glass 9.

Dans un mode de réalisation particulier d'une boîte de montre 100, et tel qu'illustré par les figures, la structure 1 est une carrure, notamment fixée à un fond 11, et le composant résonateur 2 est une lunette porteuse d'une glace 9, directement ou par l'intermédiaire d'un joint de glace 90. A ce propos, dans la variante comportant un joint de glace 90, pour faire résonner la glace 9 dans les meilleurs conditions, on choisit le matériau de ce joint de glace 90 selon les mêmes critères que le ou les joints de l'élément d'étanchéité 3, et notamment en silicone ou similaire, avec une très faible dureté Shore, de préférence inférieure ou égale à 20 Shore A.In a particular embodiment of a watch case 100, and as illustrated by the figures, the structure 1 is a middle part, in particular fixed to a base 11, and the resonator component 2 is a lens carrying a crystal 9, directly or through an ice seal 90. In this regard, in the variant comprising an ice seal 90, to resonate the ice 9 in the best conditions, the material of this ice seal is chosen. 90 according to the same criteria as the seal (s) of the sealing element 3, and in particular of silicone or the like, with a very low Shore hardness, preferably less than or equal to 20 Shore A.

Les figures 11 et 12 illustrent une vibration de la lunette 2 par rapport à la carrure 1 en mode piston, selon la direction axiale Z, dans le premier cas avec trois pattes 7 sensiblement parallèles à cet axe Z et travaillant en flambage ou en extension, et dans le deuxième cas avec trois pattes 7 perpendiculaires à l'axe Z et travaillant en flexion.The Figures 11 and 12 illustrate a vibration of the bezel 2 relative to the middle part 1 in piston mode, in the axial direction Z, in the first case with three legs 7 substantially parallel to this axis Z and working in buckling or in extension, and in the second case with three legs 7 perpendicular to the Z axis and working in flexion.

La figure 13 illustre un maintien de la lunette 2 par une patte 7 unique parallèle à l'axe Z fixée à la carrure 1, la lunette 2 est alors en porte-à-faux et oscille angulairement.The figure 13 illustrates keeping the bezel 2 by a single tab 7 parallel to the axis Z fixed to the middle part 1, the bezel 2 is then cantilevered and oscillates angularly.

La figure 14 illustre un maintien de la lunette 2 par deux pattes 7 parallèles à l'axe Z fixées à la carrure 1 et sensiblement opposées diamétralement, la lunette tend alors à pivoter autour d'un axe de lacet entre les extrémités de ces deux pattes 7.The figure 14 illustrates a holding of the bezel 2 by two legs 7 parallel to the axis Z fixed to the middle part 1 and substantially diametrically opposite, the bezel then tends to pivot around a yaw axis between the ends of these two tabs 7.

On comprend que la fixation de la glace 9 par rapport à la lunette 2 peut être faite selon des variantes similaires, et que la résonance peut donc combiner :

  • une vibration de la lunette 2 par rapport à la carrure 1, et
  • une vibration de la glace 9 par rapport à la lunette 1.
It is understood that the fixing of the lens 9 relative to the telescope 2 can be made according to similar variants, and that the resonance can therefore combine:
  • a vibration of the bezel 2 relative to the middle part 1, and
  • a vibration of the glass 9 relative to the telescope 1.

Par exemple, les figures 17 à 19 illustrent un maintien diamétral de la glace 9 en deux points opposés de la lunette 9, directement sur celle-ci, alors que sur le reste de sa périphérie la glace et la lunette sont jointes par le joint de glace 90.For example, figures 17 to 19 illustrate a diametrical retention of the glass 9 at two opposite points of the telescope 9, directly on the latter, while on the rest of its periphery the glass and the telescope are joined by the glass seal 90.

La figure 23 représente une variante avantageuse de joint, conçu à la fois pour être plaqué dans sa gorge de logement 52 par un élément saillant antagoniste lors de montage de la boîte, ce joint comportant, du côté externe de la boîte, une lèvre mince 310, ici en appui sur une surface plane 81 de la carrure 1, conçue pour se plaquer sur cette surface plane 81 d'autant plus qu'elle est soumise à une pression externe élevée. Quand on ferme la boîte 100, la compression de ce joint par l'élément saillant 61, 62, force, par un effet de bascule, la lèvre fine 310 à venir en appui sur la surface plane 81, 82. Et cet appui est ensuite renforcé par l'exercice de cette pression externe.The figure 23 represents an advantageous variant of seal, designed both to be pressed into its housing groove 52 by a protruding protruding element during assembly of the box, this seal comprising, on the external side of the box, a thin lip 310, here in support on a flat surface 81 of the middle part 1, designed to be pressed against this flat surface 81 all the more that it is subjected to a high external pressure. When the box 100 is closed, the compression of this joint by the projecting element 61, 62, forces, by a rocking effect, the thin lip 310 to come to bear on the flat surface 81, 82. And this support is then reinforced by the exercise of this external pressure.

L'invention concerne une pièce d'horlogerie 200 musicale, c'est-à-dire avec un mécanisme sonore, de sonnerie, de réveil, de boîte à musique ou similaire. Cette pièce d'horlogerie 200, notamment une montre, comporte un mécanisme 300 de sonnerie ou de jeu de mélodie agencé pour faire résonner, par exemple par un marteau 301, un cylindre à picots, ou autre moyen similaire, au moins un timbre 302 ou un clavier fixé à une structure 1 ou à un composant résonateur 2 d'une boîte 100.The invention relates to a musical timepiece 200, that is to say with a sound, striking, alarm, music box or similar mechanism. This timepiece 200, in particular a watch, comprises a mechanism 300 for striking or playing a melody arranged to cause the resonance, for example by a hammer 301, a spiked cylinder, or other similar means, at least one stamp 302 or a keyboard fixed to a structure 1 or to a resonator component 2 of a box 100.

Selon l'invention, ce composant résonateur 2 est agencé pour être assemblé de façon rigide à la structure 1, par au moins une patte 7 autorisant la vibration du composant résonateur 2 dans un intervalle de fréquences déterminé. Ce composant résonateur 2 définit avec la structure 1, quand ils sont assemblés l'un à l'autre dans une position assemblée de service, une chambre 4 qui renferme au moins un élément d'étanchéité 3 entre la structure 1 et le composant résonateur 2. Cet élément d'étanchéité 3 d'une part, et d'autre part la ou les au moins une patte 7, constituent la seule liaison mécanique entre la structure 1 et le composant résonateur 2. L'élément d'étanchéité 3 comporte un ou plusieurs joints 31, 32, en contact avec la structure 1 et le composant résonateur 2, et tous les joints 31, 32, ont une dureté inférieure ou égale à 20 Shore A, pour un amortissement minimal de la vibration du composant résonateur 2. Plus particulièrement ces joints sont en silicone.According to the invention, this resonator component 2 is arranged to be rigidly assembled to the structure 1, by at least one lug 7 allowing the vibration of the resonator component 2 in a determined frequency interval. This resonator component 2 defines with the structure 1, when they are assembled to each other in an assembled service position, a chamber 4 which contains at least one sealing element 3 between the structure 1 and the resonator component 2 This sealing element 3 on the one hand, and on the other hand the at least one tab 7, constitute the only mechanical connection between the structure 1 and the resonator component 2. The sealing element 3 comprises a or several seals 31, 32, in contact with the structure 1 and the resonator component 2, and all the seals 31, 32, have a hardness less than or equal to 20 Shore A, for minimum damping of the vibration of the resonator component 2. More particularly, these seals are made of silicone.

Dans un premier mode d'exécution, cette pièce d'horlogerie 200 comporte une boîte 100 qui est une boîte de montre selon l'une des variantes des figures 1 à 3 exposées plus haut.In a first embodiment, this timepiece 200 comprises a case 100 which is a watch case according to one of the variants of the Figures 1 to 3 exposed above.

Dans un deuxième mode d'exécution selon l'invention, au moins la structure 1 et/ou le composant résonateur 2 comporte une gorge 51, 52, qui est agencée pour recevoir une partie de plus forte section 320, d'un joint 31, 32, que comporte cet élément d'étanchéité 3, tel que visible sur la figure 4. La structure 1 et/ou respectivement le composant résonateur 2 comporte alors une telle gorge 51, 52, et le composant résonateur 2 ou respectivement la structure 1 comporte sensiblement en face de la gorge 51, 52, une surface plane 82, 81, sur laquelle repose, dans la position assemblée, une lèvre de plus faible section 310, du joint 31, 32. Le joint 31, 32, est de forme sensiblement conique, et ferme la chambre 4 avec la lèvre de plus faible section 310, qui est disposée plus à l'extérieur de la boîte de montre 100 que la partie de plus forte section 320, à l'instar d'un joint spi dans une transmission automobile.In a second embodiment according to the invention, at least the structure 1 and / or the resonator component 2 comprises a groove 51, 52, which is arranged to receive a portion of larger section 320, of a seal 31, 32, which comprises this sealing element 3, as visible on the figure 4 . The structure 1 and / or respectively the resonator component 2 then comprises such a groove 51, 52, and the resonator component 2 or respectively the structure 1 comprises substantially opposite the groove 51, 52, a flat surface 82, 81, on which rests, in the assembled position, a lip of smaller section 310, of the seal 31, 32. The seal 31, 32 is of substantially conical shape, and closes the chamber 4 with the lip of smaller section 310, which is arranged more on the outside of the watch case 100 than the part of stronger section 320, like a spinnaker joint in an automobile transmission.

La fixation relative entre la structure 1 et le composant résonateur 2 peut être réalisée de la façon décrite plus haut, avec une ou plusieurs pattes 7, et toute la description relative à la boîte de montre 100 est applicable à cette pièce d'horlogerie 200.The relative fixing between the structure 1 and the resonator component 2 can be carried out as described above, with one or more lugs 7, and the entire description relating to the watch case 100 is applicable to this timepiece 200.

Naturellement on peut combiner le premier mode et le deuxième mode de réalisation, comme sur l'exemple de la figure 20. La boîte de montre 100 comporte alors plusieurs éléments d'étanchéité 3 intérieurs les uns aux autres, et délimitant au moins un volume intermédiaire étanche. Et, plus particulièrement, un élément d'étanchéité coopérant avec un élément saillant 61, 62, est situé plus à l'intérieur de la boîte de montre 100 qu'un élément d'étanchéité à joint conique à lèvre mince.Naturally, the first mode and the second embodiment can be combined, as in the example of the figure 20 . The watch case 100 then comprises several sealing elements 3 inside each other, and delimiting at least one sealed intermediate volume. And, more particularly, a sealing element cooperating with a projecting element 61, 62, is located more inside the watch case 100 than a sealing element with a conical seal with a thin lip.

Le système vibro-acoustique selon l'invention est efficace, car l'élément rayonnant, ici le composant résonateur 2, peut vibrer librement selon ses modes propres. Le contact entre la lunette et la carrure est minimal, grâce à une construction avec une lunette fixée à une carrure rigide par l'intermédiaire de pattes ou similaire éviter un contact direct de la lunette sur tout le pourtour de la carrure.The vibro-acoustic system according to the invention is effective, since the radiating element, here the resonator component 2, can vibrate freely according to its own modes. The contact between the bezel and the middle part is minimal, thanks to a construction with a bezel fixed to a rigid middle part by means of lugs or the like avoiding direct contact of the bezel around the entire circumference of the middle part.

L'invention est utilisable avec un élément d'habillage fabriqué par électroformage, où, à cause de la structure très fine de ce type de composant, un joint est nécessaire pour résister à la pression de l'eau sans abîmer le composant lui-même. Notamment une lunette ou carrure électroformée en alliage d'or convient bien à la mise en œuvre de l'invention.The invention can be used with a covering element manufactured by electroforming, where, because of the very fine structure of this type of component, a seal is necessary to resist the pressure of the water without damaging the component itself . In particular, a bezel or electroformed middle part of a gold alloy is well suited to the implementation of the invention.

En somme, l'invention concerne un assemblage particulier d'au moins trois composants d'habillage d'une montre, où:

  • deux composants sont constitués par deux volumes solides rigides faisant partie de la boîte de la montre, comme par exemple une lunette et une carrure, un fond et une carrure, une lunette et une glace, une fond et une glace, un fond et une lunette ;
  • au moins un composant est un élément d'étanchéité comportant au moins un joint hautement déformable lors de l'opération d'emboîtage, par exemple un joint en silicone de très faible dureté Shore ;
  • au moins un des deux volumes solides rigides présente une gorge sur la face qui s'oppose à la face de l'autre volume solide lors de l'emboîtage ;
  • un composant de la forme de la boîte, qui peut être inscrit dans un volume de révolution ayant un diamètre correspondant au diamètre des deux volumes solides, et qui est rigide ou élastique, mais qui, s'il est élastique, est au moins dix fois moins déformable que le joint concerné à égalité de compression.
In short, the invention relates to a particular assembly of at least three components for covering a watch, where:
  • two components are constituted by two rigid solid volumes forming part of the watch case, such as for example a bezel and a middle part, a back and a middle part, a bezel and a crystal, a bottom and a crystal, a bottom and a bezel ;
  • at least one component is a sealing element comprising at least one highly deformable seal during the casing operation, for example a silicone seal of very low Shore hardness;
  • at least one of the two rigid solid volumes has a groove on the face which opposes the face of the other solid volume during fitting;
  • a component in the shape of the box, which can be inscribed in a volume of revolution having a diameter corresponding to the diameter of the two solid volumes, and which is rigid or elastic, but which, if it is elastic, is at least ten times less deformable than the joint concerned with equal compression.

L'invention procure des avantages importants :

  • limiter les pertes vibratoires au niveau des moyens d'étanchéité nécessaires entre un élément vibrant destiné à rayonner et la structure de la boîte de montre ou similaire;
  • diminuer l'amortissement des vibrations, ce qui conduit à une plus grande persistance du son ;
  • améliorer les performances acoustiques d'un habillage possédant ce type de solution.
The invention provides important advantages:
  • limit the vibration losses at the level of the sealing means necessary between a vibrating element intended to radiate and the structure of the watch case or the like;
  • decrease the damping of vibrations, which leads to greater persistence of sound;
  • improve the acoustic performance of a covering with this type of solution.
