Definitions

  • the invention relates to a balance-spring resonator for a timepiece and, more specifically, to such a resonator comprising fewer parts.
  • a balance-spring resonator generally has a configuration as described in FIG. figure 2 .
  • 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.
  • the balance 3 to transmit its oscillation frequency to the exhaust system comprises a pin 6 fitted in a recess of said balance.
  • the hairspring 5 comprises a hairspring 2 formed in one piece with a shell 4 which is fitted on the axis 7.
  • 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.
  • 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.
  • 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.
  • the invention also relates to a timepiece characterized in that it comprises a resonator according to one of the preceding variants.
  • 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.
  • the hairspring 15 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.
  • 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.
  • the hairspring 15 comprises in a single piece not only the hairspring 12 and the ferrule 14 but also the ankle 16.
  • the rocker 13 has a recess 19 to receive the pin 16 for the purpose that it protrudes from the rocker 13.
  • 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.
  • 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.
  • a substrate of the SOI type abbreviation well known from the English terms "Silicon On Insulator”
  • the spiral 15, that is to say the spiral spring 12 and the shell 14 is etched in the upper layer also called “device”.
  • 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.
  • 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.
  • 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.
