Definitions

  • the invention relates to a resonator mechanism with flexible guidance provided with means for adjusting the rigidity, in particular for watchmaking.
  • the balance-spring constitutes the time base of the watch. It is also called resonator.
  • an inertial element To constitute a mechanical resonator, an inertial element, a guide and an elastic return element are required.
  • a spiral spring acts as an elastic return element for the inertial element that constitutes a balance. This balance wheel is guided in rotation by pivots, which generally rotate in smooth ruby bearings.
  • the balance spring-spring system For its operation, the balance spring-spring system must generally be able to be adjusted to improve the precision of a watch.
  • means for adjusting the rigidity of the hairspring such as a racket, are used to modify the effective length of the spring.
  • racket For its operation, the rigidity of the hairspring, such as a racket, are used to modify the effective length of the spring.
  • its rigidity is modified to adjust the running precision of the watch.
  • the effect of a traditional racket for adjusting the rate remains limited, and it is not always effective in making the adjustment sufficiently precise, of the order of a few seconds or a few tens of seconds per day.
  • adjustment means comprising one or more screws arranged in the rim of the balance. By acting on the screws, the inertia of the balance wheel is modified, which has the effect of modifying its rate.
  • the object of the present invention is to overcome all or part of the drawbacks mentioned above by proposing a clockwork resonator mechanism with flexible guidance provided with precise adjustment means.
  • the invention relates to a rotary resonator mechanism, in particular for watchmaking, the resonator mechanism comprising a flexible guide and an oscillating weight, the flexible guide comprising two flexible blades and a rigid part, the flexible blades being joined on the one hand to the rigid part of the flexible guide and on the other hand to the oscillating weight.
  • the mechanism comprises means for adjusting the rigidity of the resonator mechanism, the adjustment means comprising a flexible element arranged in series with the flexible guide, the flexible element being connected on the one hand to the rigid part of the flexible guide and on the other hand to an immobile support, so that the flexible guide is suspended by the flexible element, the flexible element forming a pivot to allow the rigid part to perform a rotary movement, the flexible guide and the flexible element extending substantially in the same plane to allow the oscillating weight to perform a rotary movement around a virtual pivot, the adjustment means further comprising pre-tensioning means for applying a force or a variable torque on the flexible element or the flexible guide so as to vary the rigidity of the flexible element.
  • the prestressing means by acting on the prestressing means, the force or the torque applied to the flexible element is modified, which leads to a modification of the rigidity of the assembly comprising the flexible element and the flexible guide.
  • the flexible element placed in series with the flexible guide provides additional rigidity, which is added to that of the flexible guide.
  • the prestressing means apply a variable force or torque to the flexible element, they modify the rigidity of the flexible element and therefore of the assembly comprising the flexible guide and the flexible element.
  • a flexible element is placed in series with the flexible guide, between the flexible guide and the fixed support.
  • This flexible element modifies the rigidity of the attachment point and provides additional flexibility to the resonator.
  • the effective rigidity of the resonator includes the rigidity of the flexible guide and the rigidity of the flexible element.
  • a variable force or torque is then applied to pre-stress the flexible element without pre-stressing the flexible guide and without moving the flexible guide. By pre-stressing the flexible element, its stiffness changes, while the stiffness of the flexible guide remains unchanged, since it is not prestressed and its end does not move.
  • the rigidity of the resonator (rigidity of the flexible guide and rigidity of the flexible element) changes, which consequently modifies the course of the resonator. Since the flexible element is preferably more rigid than the flexible guide, the share of the rigidity of the flexible element in the overall rigidity is lower than that of the flexible guide. Consequently, a modification of the rigidity of the flexible element modifies the rigidity of the whole of the resonator, and consequently regulates its course in a fine way, which makes it possible to precisely adjust the frequency of our time base. Great precision is thus obtained in the adjustment of the rate, because it acts on a single element to adjust the rigidity.
  • the prestressing means only vary the rigidity of the flexible element without modifying the rigidity of the main flexible strips.
  • the flexible element comprises at least one secondary flexible strip, preferably two secondary flexible strips, each secondary flexible strip being connected to the stationary support.
  • the prestressing means comprise pins in contact with the secondary flexible blades.
  • the prestressing means apply the variable force or torque to the secondary flexible blades.
