De l'autre côté de la portée 8 de l'axe 7, est ajusté le spiral 5. Le spiral 5 comporte un ressort-spiral 2 formé en une seule pièce avec une virole 4 qui est ajustée sur l'axe 7.A balance-spring resonator generally has a configuration as described in FIG. figure 2 . Thus, the resonator 1 comprises a rocker 3 driven on an axis 7 so that it is rotatably mounted between a bridge and the plate of a watch movement. As visible at figure 2 , the balance 3 to transmit its oscillation frequency to the exhaust system comprises a pin 6 fitted in a recess of said balance.

Résumé de l'inventionSummary of the invention

Le but de la présente invention est de simplifier la fabrication dudit résonateur balancier - spiral ci-dessus en diminuant le nombre de pièces et, incidemment, en améliorant la qualité de fabrication.The object of the present invention is to simplify the manufacture of said balance-balance resonator - spiral above by reducing the number of parts and, incidentally, improving the quality of manufacture.

A cet effet, l'invention se rapporte à un résonateur balancier - spiral comportant un balancier monté sur un axe, un spiral comprenant un ressort-spiral venu de forme avec une virole et monté sur ledit axe caractérisé en ce que la virole du spiral comporte une excroissance venue de forme formant une cheville agencée pour coopérer avec un système d'échappement.For this purpose, the invention relates to a balance-spring resonator comprising a rocker mounted on an axis, a spiral comprising a spring-shaped spring with a ferrule and mounted on said axis, characterized in that the ferrule of the spiral comprises an outgrowth of shape forming an anchor arranged to cooperate with an exhaust system.

On comprend donc qu'un ensemble ressort-spiral - cheville est formé de manière monobloc ce qui autorise un positionnement parfait entre la cheville, la virole et le ressort-spiral tout en diminuant le nombre de pièces, c'est-à-dire en simplifiant la fabrication du résonateur.It is therefore understood that a spiral spring - ankle assembly is integrally formed which allows a perfect positioning between the ankle, the ferrule and the spiral spring while decreasing the number of parts, that is to say in simplifying the manufacture of the resonator.

  • l'excroissance formant une cheville est montée sensiblement parallèlement audit axe ;
  • l'excroissance est montée à travers un évidement du balancier ;

  • the spiral spring - ankle assembly is formed of silicon;

L'invention se rapporte également à une pièce d'horlogerie caractérisée en ce qu'elle comporte un résonateur conforme à l'une des variantes précédentes.The invention also relates to a timepiece characterized in that it comprises a resonator according to one of the preceding variants.

Enfin, l'invention se rapporte à un procédé de fabrication d'au moins un spiral caractérisé en ce qu'il comporte les étapes suivantes :

Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

Selon l'invention, le résonateur 11 comporte un balancier 13 chassé sur un axe 17 afin qu'il soit monté à rotation entre un pont et la platine d'un mouvement horloger. De l'autre côté de la portée 18 de l'axe 17, est ajusté le spiral 15. Le spiral 15 comporte un ressort-spiral 12 formé en une seule pièce avec la virole 14 qui est ajusté sur l'axe 17. Avantageusement selon l'invention, le spiral 15 comporte également une cheville 16 formée en une seule pièce avec le ressort-spiral 12 et reliée au niveau de la virole 14. Ainsi, le spiral 15 comporte de manière monobloc non seulement le ressort-spiral 12 et la virole 14 mais également la cheville 16.According to the invention, the resonator 11 comprises a rocker 13 driven on an axis 17 so that it is rotatably mounted between a bridge and the plate of a watch movement. On the other side of the bearing surface 18 of the shaft 17 is fitted the hairspring 15. The hairspring 15 comprises a hairspring 12 formed in one piece with the shell 14 which is fitted on the axis 17. Advantageously according to the invention, the hairspring 15 also comprises a peg 16 formed in one piece with the hairspring 12 and connected at the level of the shell 14. Thus, the hairspring 15 comprises in a single piece not only the hairspring 12 and the ferrule 14 but also the ankle 16.

Comme visible à la figure 2, le balancier 13 comporte un évidement 19 afin de recevoir la cheville 16 dans le but que cette dernière fasse saillie du balancier 13. Ainsi, de manière habituelle, la cheville 16 est destinée à transmettre la fréquence d'oscillations du résonateur 11 au système d'échappement (non représenté), c'est-à-dire, par exemple, aux cornes d'une ancre suisse. On comprend donc que la fabrication du résonateur 11 en est simplifiée en comportant moins de pièces et autorise également un positionnement parfait entre la cheville 16, la virole 14 et le ressort-spiral 12.As visible at figure 2 , the rocker 13 has a recess 19 to receive the pin 16 for the purpose that it protrudes from the rocker 13. Thus, in the usual manner, the pin 16 is intended to transmit the oscillation frequency of the resonator 11 to the system of exhaust (not shown), that is to say, for example, the horns of a Swiss anchor. It is therefore understood that the manufacture of the resonator 11 is simplified by having fewer parts and also allows a perfect positioning between the pin 16, the ferrule 14 and the spiral spring 12.

Préférentiellement selon l'invention, l'ensemble ressort-spiral 12 - cheville 16, c'est-à-dire le spiral 15, est formé à base de silicium et, plus précisément, à base de silicium monocristallin. Cela est rendu possible par l'utilisation d'un substrat du type S.O.I. (abréviation très connue venant des termes anglais « Silicon On Insulator »). En effet, dans un premier temps, le spiral 15, c'est-à-dire le ressort-spiral 12 et la virole 14, est gravé dans la couche supérieure également appelée « device ». Tandis que, dans un deuxième temps, la cheville 16 du spiral 15 est gravée dans la couche inférieure également appelée « handle ». L'ensemble ressort-spiral 12 - cheville 16 n'aurait alors, dans un troisième temps, qu'à être libéré du substrat. On comprend qu'une fabrication en série devient possible par gravage de plusieurs spiraux 15 sur le même substrat S.O.I..Preferably according to the invention, the spiral spring assembly 12 - pin 16, that is to say the spiral 15, is formed based on silicon and, more precisely, based on monocrystalline silicon. This is made possible by the use of a substrate of the SOI type (abbreviation well known from the English terms "Silicon On Insulator"). Indeed, initially, the spiral 15, that is to say the spiral spring 12 and the shell 14, is etched in the upper layer also called "device". While, in a second step, the pin 16 of the spiral 15 is etched in the lower layer also called "handle". The spring-spiral assembly 12 - pin 16 would then, in a third time, only to be released from the substrate. It is understood that mass production becomes possible by etching several spirals 15 on the same SOI substrate.

Bien entendu, la présente invention ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art. En particulier, une oxydation finale peut intervenir afin d'améliorer la solidité et/ou ajuster le coefficient thermique du résonateur 11 de tout ou partie de l'ensemble ressort-spiral 12 - virole 14 - cheville 16.Of course, the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art. In particular, a final oxidation can take place in order to improve the solidity and / or to adjust the thermal coefficient of the resonator 11 of all or part of the spring-spiral assembly 12 - ferrule 14 - pin 16.
