  • the invention proposes to provide subassemblies with reduced number of components, and assembly and adjustment of average complexity.
  • the mounting of a spiral spring is a delicate operation to automate.
  • the design of a spiral spring integrated with an easier handling subassembly allows a better automation of the assembly.

  • This adjustable component 82 comprises indexing means 84, which are arranged to cooperate with complementary indexing means 91 that comprises an adjustment mechanism 90.
  • These complementary indexing means 91 are detachably mounted indexing means 84, and are lockable in the cooperation position by a locking mechanism 94 resiliently fixed to the structure 81.
  • This blocking mechanism 94 is itself even subject to the action of a locking mechanism 98 which allows it to occupy, or a disengaged position in which the adjustment mechanism 90 is free, or a position engaged in the the locking mechanism 94 obstructs the adjustment mechanism 90.
  • This locking mechanism 98 is also resiliently attached to the structure 81.
  • this mechanism adjustable in position 80 carries an adjustable component in position 82 which carries a bearing 44 or a bearing holder 13 receiving the pivot of a rocker 41 for receiving the inner end of the spiral spring 71, with the same architecture as before.
  • this adjustable component in position 82 comprises indexing means 84, which are arranged to cooperate with complementary indexing means 91, here constituted by a comb, or a toothed sector, which comprises an adjustment mechanism 90.
  • complementary indexing 91 are mounted disengageable indexing means 84. They are still lockable in the cooperation position by a locking mechanism 94.
  • This blocking mechanism 94 is resiliently fastened to the structure 81 by at least one flexible element 96, and is preferably itself subjected to the action of a locking mechanism which allows it to occupy, or a position disengaged in which the adjustment mechanism 90 is free, or an engaged position in which the blocking mechanism 94 obstructs the adjustment mechanism 90.

  • the latter is shaped fork, so as to limit the stroke of an arm 93 that includes the comb 91.
  • the figure 8 illustrates a similar example where the comb 91 is held between two substantially aligned flexible blades 92 and 92A, and forms a bistable component, working in buckling substantially aligned, the assembly can occupy two stable positions: a first armed position A where the comb 91 cooperates with a finger 84 of a mobile peg 82, and a second disarmed position B where it is disengaged.
  • the figure 9 illustrates a similar mechanism with a comb 91 immobilizing an index 84 located at the end of a flexible blade 83, the comb 91 being pressed on this index 84 by a locking spring blade 96 belonging to the blocker 94, itself immobilized by a locking pin 99 mounted on at least one flexible blade 98, this finger 99 cooperating with a stop surface 97 of the blade 96.
  • this combined mechanism of adjustment, locking and locking illustrated here for a particular application of adjusting a stud in a race concentric to the axis of a spiral, is applicable to a wide variety of applications: positioning of a bearing, an abutment, a racket pin, or other.
  • the bridge 3 forms a single-piece component that can not be dismantled with at least one anti-shock bearing for receiving a pivot of a rocker arm 41 intended to receive the inner end of the spiral spring 71, or of a component of the escape mechanism .
  • the bridge 3 comprises, for the pivoting of a rocker arm 41 intended to receive the inner end of the spiral spring 71, a pivot 45 housed in a bearing holder 13 connected to the bridge 3 by elastic return means 14. similarly, such a pivot 45 can be arranged at the level of the plate 2.
  • the pivot 45 may be constituted by a conventional pivot or by a flexible guide.
  • the pivot 45 is a flexible one-piece guide with the bridge 3 or with the plate 2, as the case.
  • the rocker arm 41 has a one-piece end with a flexible guide and the bridge 3 (or respectively the plate 2), the rocker then has a stroke which is limited by the deflection of the flexible guide, which is then advantageously made in several stages to allow sufficient angular travel for the balance, which is then in one piece with the bridge 3 (or respectively the plate 2).
  • a flexible guide may be constituted by the spiral spring 71 itself.
  • the rocker 41 is hooked to both the bridge 3 and the plate 2, on each side by a flexible guide constituting a spiral spring 71, these two spiral springs 71 exerting couples, or in the same sense, or in opposite senses.
  • these elastic return means 14 are integral with the bridge 3 and the bearing holder 13, and, in one variant, the pivot 45 is also part of this monobloc subassembly 1.

  • the pivot points of the pivots 45 are defined, for example, by anisotropic etchings (KOH) in a silicon substrate.
  • KOH anisotropic etchings
  • a version with an assembly of the stones is also possible.
  • the big advantage is the very precise positioning of the pivot points (center distance, verticality).
  • Anti-shock can thus be partially or completely made in the plate: the spring of the shock can be achieved in common with the plate.
  • One of the two (or both) stones can be made in common with the plate. Pivoting is then done directly in the silicon.
  • the pivot points can be made directly in silicon with surface coatings of the DLC or other type. So there is no more stone, and the rotation points are positioned very precisely.
  • the subassembly 1 comprises breakable elements, intended to facilitate its assembly in an upper assembly, it is sufficient to then break these breakable elements to give one or more degrees of freedom to some of its constituents .
  • these breakable elements are located at the inner end of the hairspring, in connection with the bridge, and are broken only during assembly of the balance 41 and the attachment of the hairspring 71 to the shell of this balance.
  • the subset 1 comprises the entirety of an escape mechanism.
  • the intrinsic elastic return means that comprises the subset 1 comprise at least one bistable or multistable flexible element, as visible for example on the figure 8 , which shows a bistable element working in buckling, and having a comb 91 between two substantially aligned resilient blades 92 and 92A, the assembly being able to occupy two stable positions: a first armed position A where the comb 91 cooperates with a finger 84 of a mobile peg 82, and a second disarmed position B where it is disengaged.

  • the bridge 3 is made of micro-machinable material, or silicon, or oxidized silicon, and intrinsic elastic return means that it comprises are prestressed in a state oxidized silicon.
  • Other materials according to MEMS or "LIGA" technologies can be implemented. Quartz, DLC, at least partially amorphous materials, metallic glasses, can, and not exclusively, be used for these applications.
  • a particular structuring of the bridge 3, and / or unbreakable integral components that it comprises, may make it possible to compensate for the effects of the expansion of these structural elements, or of the components of the mechanism of the subassembly 1. It is possible for example to make the bridge 3 in silicon, then to oxidize it, in order to work coherently.
  • the invention also relates to a mechanical clockwork movement 100 comprising at least one such subassembly 1.
