Definitions

  • the invention relates to the field of watchmaking, and more particularly to the field of mechanical watchmaking, where the regulation of the driving energy is provided by a regulating organ.
  • the invention relates more specifically to a stud holder for a timepiece regulating organ provided with means for adjusting the rate and/or isochronism, as well as a regulating organ comprising such a stud holder, and a timepiece movement comprising such a regulating organ.
  • the energy required to rotate the hands (e.g., the minute and hour hands) is stored in a barrel and then delivered by a balance-spring system, which includes a flywheel called a balance wheel, combined with a spring in the form of a spiral-wound ribbon called a balance spring.
  • a balance-spring system which includes a flywheel called a balance wheel, combined with a spring in the form of a spiral-wound ribbon called a balance spring.
  • the balance spring is fixed to a shaft which rotates with the balance wheel; at one external end, the balance spring is fixed to a stud mounted on a stud holder which is itself fixed to a fixed bridge (or balance cock).
  • the balance wheel's rotation is maintained - and its oscillations counted - by an escapement mechanism comprising an anchor driven by a low-amplitude oscillating movement, equipped with two pallets which engage the teeth of an escape wheel.
  • the escape wheel is imposed a step-by-step rotational movement whose frequency is determined by the oscillation frequency of the anchor, itself set to the oscillation frequency of the sprung balance.
  • the oscillation frequency is about 4 Hz, or about 28,800 vibrations per hour (A/h).
  • A/h the oscillation frequency
  • this index system is fixed in rotation relative to the balance spring axis.
  • the assembly comprising the bridge, the index system, the key, the stud holder, the stud, the arbor, the balance spring and the balance wheel is commonly referred to as the "regulating organ".
  • regulating organs are provided by the international application WO 2016/192957 and by the European patent EP 2 876 504 , both in the name of the watch manufacturer ETA.
  • the stops are adjustable to tighten the hairspring to eliminate play, especially during operation of the hairspring.
  • the rate is first adjusted by moving the index key, then the hairspring is tightened with the key. But tightening the hairspring with the index key risks constraining it, and creating defects chronometric, in particular by decentering the coils.
  • removing the play also modifies the rate, and once the hairspring is tightened, the index key can no longer be moved along the hairspring to finely adjust the rate.
  • hairsprings have integrated rate adjustment means.
  • the rate is not adjusted by changing the effective length of the hairspring, but by applying a force or torque to a flexible element arranged in series with the hairspring. This allows the stiffness of the flexible element and consequently of the hairspring as a whole to be changed. Adjusting the stiffness of the hairspring makes it possible to adjust the rate of the regulating member.
  • Such a hairspring with a flexible element is, for example, described in patent applications EP21202213.1 And CH0700385/2021 .
  • the racket system comprises a stud holder in two movable parts, one relative to the other, each element being provided with a stud on which the flexible element is mounted on the one hand, and the prestressing means acting on the flexible element on the other hand.
  • the force or torque applied to the flexible element is modified, in order to adjust the stiffness of the hairspring.
  • the index system is complex to implement, because the moving elements of the piton holder each perform a rotary movement above the balance spring.
  • the spiral spring has a particular shape, because the flexible element and the pre-stressing means are mounted directly on the spiral spring, or even the spiral spring and the adjustment means are monobloc. Thus, it is not possible to use a conventional spiral spring with this index system.
  • the aim of the present invention is to overcome all or part of the drawbacks mentioned above by proposing a stud holder compatible with conventional balance springs, and which can provide the same advantages of precision in the adjustment of the rate and/or isochronism as a balance spring provided with adjustment means such as that of the state of the art.
  • the invention relates to a stud holder for a regulating member of a watch movement, the regulating member comprising an inertial mass, for example a balance, a balance spring comprising a ribbon wound on itself in several turns, and a balance bridge, the stud holder comprising a main body intended to be mounted on the balance bridge, a secondary body arranged at a distance from the main body and configured to suspend the balance spring, the regulating member comprising a flexible element connecting the main body to the secondary body.
  • the regulating member comprising an inertial mass, for example a balance, a balance spring comprising a ribbon wound on itself in several turns, and a balance bridge
  • the stud holder comprising a main body intended to be mounted on the balance bridge, a secondary body arranged at a distance from the main body and configured to suspend the balance spring
  • the regulating member comprising a flexible element connecting the main body to the secondary body.
  • the invention is remarkable in that the stud holder comprises prestressing means for applying a variable force or torque to the flexible element in order to adjust the rate and/or the isochronism slope of the regulating member.
  • the invention it is possible to use hairsprings of conventional shape, that is to say, in particular without a flexible element mounted or formed directly on the hairspring.
  • the flexible element is arranged on the stud holder, so that it is sufficient to mount the hairspring on the stud holder to obtain the same advantages as a hairspring provided with means for adjusting the stiffness of the state of the art.
  • the flexible element and the prestressing means of the stud holder form means for adjusting the rate and/or isochronism of a regulating organ fitted with a spiral spring.
  • the prestressing means By acting on the prestressing means, the force or torque applied to the flexible element is modified, which results in a modification of the stiffness of the assembly comprising the flexible element and the ribbon. Indeed, the flexible element placed in series with the ribbon provides additional stiffness to the ribbon, which is added to the remainder of the ribbon. Thus, when the prestressing means apply a variable force or torque to the flexible element, they modify the stiffness of the flexible element and therefore of the assembly comprising the ribbon and the flexible element.
  • the stiffness of the flexible element can be adjusted, to adjust the operation of the regulating organ.
  • the flexible element allows the secondary body to rotate relative to the main body, and consequently, to adjust the isochronism slope of the regulating organ.
  • the flexible element comprises two crossed flexible blades connecting the main body to the secondary body.
  • the two flexible blades are attached to each other at their crossing.
