Definitions

  • the present invention relates to a device for assembling and adjusting a hairspring intended to cooperate with a terminal turn of a hairspring whose inner end is integral with a balance shaft, the latter being pivoted in a bridge. balance.
  • the outer end of the hairspring is immobilized by a peg fixed to a peg holder secured to a cock.
  • a racket movable in rotation relative to the bolt carrier is provided to adjust the active length of the hairspring.
  • the racket can have two arms: a first bearing two pins between which the hairspring is free, a second, optional, serving as a lever to rotate the racket along the axis of the pendulum.
  • the racket pivots the active length of the hairspring is reduced or increased.
  • the patent application WO 2006/102911 A1 presents an example.
  • the device presented in this document comprises a single arm frictionally mounted on the balance bridge to allow adjustment of the marker.
  • the arm is provided with a circular groove defining a service position of the end turn of the spiral at the bottom of which it is maintained in support by a rotary member striated on the portion of its periphery arranged in abutment against the hairspring.
  • the striated rotary member thus defines the active length of the hairspring, while two pins are carried by the other hand by the arm, on either side of the corrugated rotary member and close to the circular groove, for ensure guidance of the end turn.
  • a main disadvantage of this device comes from the structure of the cooperating bodies with the final turn of the spiral. Indeed, the latter is extremely fragile and delicate, and its chronometric properties degrade very quickly due to mechanical stresses it could suffer.
  • the mechanical stress experienced by the hairspring because of its interaction with the striated rotary member, has a significant risk of degradation of its qualities.
  • the rotary member must necessarily apply some pressure on the hairspring to ensure its drive, which causes damage to the hairspring.
  • the hairspring may suffer further damage by its cooperation with the guide pins.
  • this type of pin requires a manual recovery, after mounting on the arm, to precisely adjust the distance separating it from the bottom of the circular groove.
  • An object of the invention is to overcome the drawbacks of assembly devices and adjustment of a spiral already known, by providing such a device for performing a simplified assembly and adjustment of the spiral, free of any mechanical stress that could cause damage to the hairspring.
  • the first and second configurations of the control member are stable configurations.
  • the shoe defining the active length of the hairspring can be removed from the base of the device, when the hairspring is put in place or when a watchmaker makes its adjustment, then resume precisely its service position.
  • control member comprises an eccentric arranged on the second arm so that it can be pivoted in response to an action of a user, to switch from one to the other of its configurations and exert pressure on the base, in the second configuration, such that the shoe is located at a distance from the support surface greater than the predefined distance.
  • control member may comprise an eccentric arranged on the base such that it can be rotated in response to an action of a user, to switch from one to the other of its configurations and exert pressure on the second arm, in the second configuration, such that the shoe is located at a distance from the support surface greater than the predefined distance.
  • the second arm may advantageously comprise, from the base towards its free end, a first substantially radial portion and terminated by a bend ensuring the connection with a second substantially tangential portion, the first and second portions and the bend being arranged such that whereby the elastic deformation experienced by the second arm, in response to a change of configuration of the control member, occurs essentially at the level of the first portion.
  • the first arm may advantageously comprise, from the base towards its free end, a first substantially radial portion and terminated by a bend ensuring the connection with a second substantially tangential portion, the first and second portions and the elbow being arranged such that the first arm is able to undergo an elastic deformation intervening essentially at the level of its first portion.
  • a locking member can be used which is not likely to cause damage to the hairspring.
  • the locking member being also carried by an elastic arm, the pressure it applies to the spiral can be adjusted finely and the integrity of the spiral is not compromised in case of shock.
  • the locking member comprises a wheel arranged on the first arm so that it is pivotable in response to a suitable action of a user to drive the end turn in translation in one direction. or in the other depending on its direction of rotation.
  • the wheel may advantageously comprise a substantially cylindrical portion of synthetic material intended to be arranged in abutment against the end turn in its service position.
  • the shoe is arranged in abutment against the base of the device in the first position of the second arm which carries it, so that it can be positioned at the predetermined distance from the bearing surface. with great precision.

  • the view of the figure 1 corresponds to a watch movement face that would be directly accessible, for example its bridges side, while the view of the figure 2 would be a view of the balance-spiral platinum side.
  • a hairspring 1 is fixed to a balance shaft 2 by its internal end (not visible).
  • the balance shaft 2 has one end pivotally mounted in a balance bridge 6 in a conventional manner.

  • the first and second arms 20, 22 are only partially illustrated in these figures for clarity.
  • the mounting plate 62 comprises a central hole 64 in which is arranged the second portion 56 of the locking member 52, so that the fourth portion 60 is housed in a hole 66 adapted to the first arm 20 to be accessible, such as that this appears in particular from the figure 1 .
  • the third portion 58 of the locking member 52 is, in turn, housed in a recess 68 adapted to the first arm 20 to lock the locking member 52 between the first arm 20 and the mounting plate 62.
  • the mounting plate 62 also comprises two pillars 70, arranged on either side of the central hole 64 and each having a curved face to provide a rotational guiding function of the locking member 52.
  • the second arm 22 carries a guide member 72 of the end turn 8, as it appears from the figure 3 .

  • the locking member When the eccentric 84 is in its second configuration, the locking member may for example be neutralized to allow translation of the end turn 8 with reference to the base 14, or an adjustment of the active length of the hairspring 1.
  • the locking member 52 is arranged in its support (the mounting plate 62) so as to be pivotable. So, when the eccentric 84 is in its second configuration, it is sufficient to rotate the locking member 52 in the counterclockwise direction on the figure 6 to shorten the active length of the hairspring or clockwise to lengthen it.
  • the locking member 52 thereby performs a wheel function, without causing any damage to the balance spring 1 given the manner in which it is constructed, as previously discussed.
