Definitions

  • the invention relates to an oscillator comprising a resonator of the inertia - elasticity type cooperating with a detent escapement.
  • the detent escapement systems are known for bringing high accuracy to marine chronometers in the 18th century by offering a direct pulse and low sensitivity to friction. However, they have proved particularly difficult to adjust and sensitive to shocks.
  • Some marine chronometers have been mounted under vacuum, in sand or on cardan suspensions to avoid any transmission of shocks inducing gallop, that is to say the accidental passage of two teeth of the escape wheel instead of one, proper to disrupt the running of the timepiece.
  • shocks inducing gallop that is to say the accidental passage of two teeth of the escape wheel instead of one, proper to disrupt the running of the timepiece.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing an oscillator comprising a resonator of the inertia-elasticity type cooperating with a detent escapement which is reliable, compact, free from gallop and whose positioning of the organs between they are very precise.
  • the invention relates to an oscillator comprising a resonator of the inertia-elasticity type cooperating with a detent escapement comprising a detent cooperating with an escape wheel, characterized in that the resonator is in one piece and comprises a compression member.
  • the trigger is also in one piece and comprises a body forming a rest lift cooperating with the escape wheel, a second flexible guide forming a virtual pivot axis of the trigger and a release spring cooperating with a stop formed at one end of the body of the trigger and in that the inertia member forms a pulse lift cooperating with the escape wheel and a release lift cooperating with the disengagement spring.
  • the oscillator has very few parts to mount because they are mostly monoblock which further allows that the elements of the parts are already perfectly referenced with respect to each other.
  • the oscillator is very compact thanks to the use of flexible guides that reduces the thickness required by excluding the use of pivots and inherently induces the elimination of gallop.
  • the oscillator according to the invention advantageously makes it possible to increase the frequency of the resonator without reducing the overall efficiency of the oscillator in comparison with an oscillator using a Swiss lever escapement. Therefore, the oscillator according to the invention is sufficiently compact and reliable to consider its application to a wristwatch.
  • the invention relates to an oscillator for a timepiece, that is to say a resonator coupled with a distribution system and maintenance such as, for example, an exhaust system.
  • the oscillator comprises a resonator of the inertia-elasticity type which cooperates with a detent escapement.
  • the latter comprises a trigger which cooperates with an escape wheel.
  • the resonator is monoblock.
  • the resonator thus comprises, in one piece, an inertia member and a first flexible guide.
  • the latter forms the elasticity of the resonator and a virtual pivot axis of the resonator which avoids having to use the usual bearings and pivot.
  • the amplitude of the resonator is limited to the maximum deflections of the first flexible guide. This limitation of the deflections nevertheless makes the resonator gallop inherently impossible, which by construction resolves the main problem which usually penalizes the exhaust systems with detent.
  • the trigger is also monoblock according to the invention. It thus comprises, in one piece, a body, a second flexible guide and a disengagement spring cooperating with a stop formed at one end of the body of the trigger. This set is usually very difficult to adjust and the monoblock aspect according to the invention advantage as to the positioning accuracy of the assembly.
  • the body of the detent is provided with a one-piece rest lift which cooperates with the escape wheel which avoids the use of an additional dowel and contact with the escape wheel in another plane than the body of the relaxation.
  • the second flexible guide forms a virtual pivot axis of the trigger.
  • the first flexible guide the second flexible guide avoids having to use the usual bearings and pivot.
  • the release spring cooperates with an abutment formed at one end of the body of the detent.
  • the inertia member is directly provided with a pulse lift, that is to say that the pulse lift is in one piece with the inertia member.
  • the pulse lift cooperates directly with the escape wheel. It is therefore understood that no intermediate part is used between the organ of inertia and the escape wheel making the impulse even more direct than a usual detent escapement system.
  • the inertia member is also directly provided with a release lift, that is to say that the release lift is also monobloc with the inertia member.
  • the release lift cooperates directly with the release spring.
  • the pulse lift it is therefore understood that no intermediate part is used between the inertia member and the release spring making more compact and even more direct clearance relative to a system of usual detent escapement.
  • the one-piece resonator is formed in first and second integral levels and the one-piece expansion is formed in first and second integral planes, the first and second levels respectively being coplanar or offset with respect to the first and second planes. It can be understood that the thickness of the resulting assembly can be drastically reduced compared with an oscillator using a conventional balance-spring resonator cooperating with a usual expansion escapement system.
  • the one-piece resonator and the one-piece expansion can be formed in two single plates secured to form a single-piece oscillator assembly whose resonator and trigger are ideally referenced with respect to each other. It immediately emerges the advantage of a perfectly referenced assembly that is mounted in one piece in the watch movement without special precautions or fine adjustment to comply.
  • This one-piece oscillator assembly could, for example, be made from silicon-bonded plates as typically a silicon-on-insulator substrate (known by the abbreviation "SOI"). However, all materials that can be joined together and can be etched posteriorly face to face, as a silicon on insulator substrate, can be used.
  • SOI silicon-on-insulator substrate
