Definitions

  • the present invention relates to a balance spring-balance member for a timepiece comprising a rocker, a spiral spring, a stud and a stud holder, the spiral spring having one end connected to the rocker and being fixed by the other end to piton, the bolt itself being held rigidly in place by the bolt carrier.
  • the present invention relates more specifically to the assembly formed by the assembly of the stud and the stud holder.
  • Regulating members comprising a balance and a hairspring whose inner end is fixed rigidly to a hoop driven on the axis of the balance beam, while the outer end of the hairspring is fixed rigidly to a pin carried by a holder. angle displaceable angularly concentrically to the axis of the balance.
  • the bolt carrier is pivoted to hard friction on a part of the cock (or balance beam) concentric with the balance shaft.
  • a watchmaker can adjust the angular position of the stud and the outer end of the hairspring by simply pivoting the bolt carrier relative to the pendulum. This manipulation is important because the angular position of the outer end of the spiral must be such that the plateau pin is in the anchor-balance axis when the balance is in its equilibrium position.
  • the adjustment of the position of the spiral spring relative to the balance shaft must be precise. In fact, an off-centering of the spiral spring or a defect of perpendicularity with respect to the balance shaft generates significant chronometric defects, in particular at the level of the isochronism of the regulator.
  • the pin must be perpendicular to the plane of the spiral spring and positioned accurately to ensure a concentric development of the spiral spring. In practice, the adjustment of the position of the peak is delicate because access is restricted and the parts concerned are very small. With traditional metal alloy spiral springs, once the outer end of the balance spring is fixed to the balance bridge by the pin and the bolt carrier, the residual deviations from the ideal three-dimensional shape of the spiral spring can still be corrected by deformation. Plastic end of the spiral spring.
  • the spiral spring is made of a brittle material, such as silicon, diamond or quartz
  • adjustment by plastic deformation as above is not possible.
  • the use of a pin imposes very tight manufacturing tolerances and a robust piton-spiral assembly, so as to obtain the most perfect perpendicularity possible between the pin axis and the plane of the spiral spring .
  • this imperative represents a major difficulty on an industrial scale, when we know that the simple fact of immobilizing the stud in its housing by tightening a screw can suffice to distort its orientation.
  • the patent CH 347 769 describes an assembly formed of a bolt carrier and a bolt, the bolt carrier having a slot-shaped groove arranged to receive longitudinally and position the bolt, the housing being at least partially closed laterally by an elastic blade mounted on the bolt carrier.
  • the elastic blade is permanently in contact with the peak, which makes its adjustment complex.
  • the patent CH 76336 describes a set consisting of a peg and a peg, the peg carrier having a notch for receiving the peak.
  • the bolt is held on the bolt carrier by a spring.
  • the spring can be deformed by means of a screw to separate it from the pin and allow its adjustment or its exit from the notch.
  • such a spring represents a large amount of space.
  • the document CH 368098 describes an assembly formed of a peg and a peg, the bolt carrier having a housing for receiving the bolt, the housing being at least partially closed laterally by a plate.
  • An object of the present invention is to overcome the drawbacks of the prior art which have just been mentioned by providing a set formed of a stud and a peg holder and which offers the possibility of adjusting the position of the peak relative to the bolt carrier and then to immobilize the bolt more easily without using a screw.
  • the present invention achieves this goal by providing an assembly formed of a bolt and a bolt carrier according to the appended claim 1.
  • the figure 3 shows a balance-sprung regulator member for a timepiece corresponding to a particular embodiment of the invention.
  • the balance 7 whose axis is rotated between two bearings.
  • one of these bearings (referenced 11) is supported by the cock 9, while the other bearing is mounted in the plate (not shown).
  • the balance is associated with a hairspring 1 whose central end is fixed to the axis of the balance.
  • the cock 9 also serves as a support for an assembly constituted by the stud 3 and the stud holder 5.
  • This assembly is intended to position the outer end 1a of the hairspring 1.
  • the end 1a is first fixed rigidly to the peg by gluing. To do this, first introduces the end of the spiral in a notch (not shown) of the peak. The hairspring is then locked in the notch by gluing.
  • the invention is not limited to a particular method of fixing the end 1a of the spiral on the peak.
  • the end 1a could, just as well, be for example fixed to a conventional stud pin. Or, according to yet another variant, it is possible to provide the stud 3 and the spiral 1 of material in one piece.
  • the bolt carrier 5 essentially consists of an annular portion concentric with the balance shaft, and an arm-shaped extension which carries the stud 3 and which extends radially with respect to the axle. axis of the balance 7, towards the outer turns of the spiral.
  • the extension of the bolt carrier 5 has a housing 13 oriented parallel to the axis of the balance 7 and in which the piton and inserted longitudinally.
  • the bolt carrier 5 is pivoted to hard friction by its annular portion on a portion of the cock 9 which is concentric with the pendulum.
  • the housing 13 is formed by a straight groove which is closed over most of its length by a flexible thin blade 15.
  • the blade 15 is arranged to tighten and immobilize the peak 3 against the bottom of the groove by elastic pressure.
  • the figure 4 shows again that the blade 15 comes from material with the walls of the groove and that it extends without discontinuity from one wall to the other of the latter.
  • the blade could not extend from one wall to the other of the groove, but on the contrary be secured to only one wall and to extend in cantilever.
  • the blade could also not come from material with the bolt carrier, but be fixed to the bolt carrier by one of the sides of the groove (or by both sides).
  • the bolt carrier is preferably made of silicon, but that it could also be made of another material.
  • the bolt carrier could be made of metal or composite material. If the peak is made of metal, it is preferably formed by galvanic deposition according to the LIGA technique.
  • the blade 15 carries a fastening structure 17 provided to allow a watchmaker to pull the blade back to release the peak. More specifically, when a watchmaker wants to adjust the position of the stud 3 vis-à-vis the door stud 5, it can use a tool (not shown) adapted to cooperate with the attachment structure 17. Thus, thanks to the attachment structure, it can move the elastic blade 15 so as to clear the peak. Recall that the illustrated blade 15 is attached to both sides of the groove. Moreover, by referring always at the figure 4 it can be seen that, in accordance with the illustrated embodiment, the blade forms a curved arc towards the bottom of the groove. An advantage of this configuration is that it gives the blade 15 two distinct stable positions.
  • the second position corresponds to the situation in which the curvature of the blade is reversed; the blade then forming a curved arc towards the outside of the groove. It will be understood from the foregoing that by removing the blade 15 of the peak 3, the watchmaker will blow the blade from its first to its second stable position, so that the blade will no longer support against the peak. This second position being stable, it is not necessary then to hold the blade during the adjustment of the position of the peak. Once the stud is correctly positioned, it suffices for the watchmaker to push the blade towards the bottom of the throat so that the latter jumps from its second to its first stable position, again immobilizing the stud.
  • the shape of the stud 3 is essentially cylindrical.
  • One advantage of the rotational symmetry inherent in the cylindrical shape is that the position of the stud relative to the stud holder 5 can be adjusted, not only longitudinally, but also in rotation.
  • This additional possibility may be advantageous when the spiral spring is made of a brittle material. Indeed, when the spring is made with such a material, it is in principle not possible to correct a possible deflection of the spring plastically deforming its end.
  • the figure 5 is an enlarged partial view showing the assembly of a bolt and a bolt carrier forming part of a regulating member conforming to a second embodiment of the invention.
  • the blade 215 can occupy two distinct stable positions. It will be understood that the position represented in the figure 5 is that in which the blade immobilizes the stud 203 against the bottom of the groove by elastic pressure.
  • the second position, not shown, corresponds to the situation in which the curvature of the blade is reversed.
  • the blade 215 is made of material with an edge of the groove to which it is connected by one of its sides.
  • the other side of the blade is connected to a flexible arm, or spring 212, which is also integral with the remainder of the bolt carrier.
  • An advantage associated with the presence of the flexible arm 212 is that it reduces the work required to blow the blade 215 from one of these stable positions to another, while maintaining the blade buckling.
  • the housing arranged in the bolt carrier to receive the bolt may, according to a first variant, be through.
  • this housing could only lead to the side of the spiral.
