Definitions

  • the invention relates to an autonomous adjustment device for the active length of a spiral, for a balance-spiral type oscillator.
  • the invention also relates to a watch movement comprising the autonomous adjustment device for the active length of a balance spring and a balance-spring type oscillator.
  • the invention further relates to a timepiece, in particular a watch, comprising the watch movement.
  • the outer end of the balance spring is held in place by a stud attached to a stud holder fixed to a balance cock.
  • a regulator which rotates relative to the stud holder, is used to adjust the active length of the balance spring, thus allowing the balance wheel's frequency to be adjusted.
  • the regulator is a lever, usually with two arms, that pivots centered on the balance staff.
  • One arm of the regulator for example, carries two pins between which the balance spring is free.
  • a second arm of the regulator can be manually operated to rotate the regulator by a certain angle around the balance staff. This allows the actual position of the counting point to be changed.
  • the active length of the balance spring is reduced or increased.
  • a drawback of such a manual adjustment device is that Earth's gravity influences the frequency of the balance wheel's oscillations depending on the orientation of the watch movement. correspondingly, a watch's rate can vary significantly between its horizontal and vertical positions, in particular. Furthermore, when the balance spring moves between the pins due to play between them, the oscillations of the balance wheel and hairspring cause a disturbance in its active length and therefore a slight variation in the frequency of the oscillations of the entire balance wheel and hairspring assembly.
  • the document EP 3 502 788 A1 discloses a device for autonomously adjusting the active length of a balance spring.
  • the invention therefore aims to provide a device for adjusting the active length of a spiral, for a balance-spring type oscillator, allowing to counterbalance in a simple, precise and autonomous way the effects of gravity, in particular the perturbations of the isochronism of the balance wheel of the oscillator, and overcoming the aforementioned disadvantages of the prior art.
  • the invention relates to an autonomous adjustment device for the active length of a balance spring, for a balance-spring type oscillator, comprising a cock mounted on a plate of a watch movement and in which a balance shaft pivots, the balance spring having an inner end fixed to the balance shaft and an outer end fixed to a stud attached to a stud holder, the stud holder being pivotally mounted on the cock concentrically to the balance shaft, and means for modifying the active length of the balance spring.
  • the adjustment device comprises weights mounted to move in translation and cooperate indirectly with a movable arm arranged to act on the coil. external to the balance spring.
  • a displacement of the weight, freely subjected to gravity thus causes a displacement of the arm between a rest position and a correction position of the device, and simultaneously acts on the balance spring to modify its active length, allowing it to be adjusted to compensate for perturbations in the isochronism of the balance wheel due to gravity. Therefore, the adjustment device according to the invention makes it possible to precisely compensate for the oscillator's rate as a function of its position in space, counterbalancing perturbations in the isochronism of the balance wheel due to gravity, and to do so autonomously.
  • the invention also relates to a watch movement comprising the setting device described above, and which includes the features mentioned in dependent claim 14.
  • the invention also relates to a timepiece comprising the clock movement described above, and which includes the features mentioned in dependent claim 15.
  • the following description refers to a watch movement equipped with a device for adjusting the active length of a balance spring, for a balance-spring type oscillator.
  • the usual components of a watch movement which are well known to a person skilled in this technical field, are described only in simplified form or not at all. A person skilled in the art will be able to adapt these various components and make them work together for the operation of the watch movement. In particular, everything concerning the escapement mechanism of the watch movement will not be described hereafter, although such an escapement mechanism could advantageously cooperate with the adjusting device according to the invention.

  • the timepiece 1 is a watch.
  • the watch movement 2 comprises an oscillator equipped with a balance wheel 4 and a balance spring 5, and a device 6 for independently adjusting the active length of the balance spring 5.
  • the balance spring 5 is attached to a balance staff (not visible) by its inner end (also not visible).

  • the rotation of the first cam 30 causes a displacement of the first arm 60 to act on the balance spring and simultaneously modify the active length of the balance spring 5, and the same is true for the second cam 31, which is arranged to cooperate with the second arm 61.
  • Each of the weights 40, 41 is in the form of a linear body having two guide grooves 400, 401, 410, 411 extending along the length of each weight and arranged on opposite faces of each weight.
