Definitions

  • the invention relates to a racket key to ensure the frolicking of the spiral even in case of shocks.
  • shockproof devices are bulky and / or do not allow intervention after-sales to, for example, change the spiral.
  • the object of the present invention is to overcome all or part of the drawbacks mentioned above by proposing a new racket key whose arms can ensure the frolicking of the spiral even in case of shocks while remaining compact.
  • the invention relates to a racket key for a watch movement comprising a base arranged to be attached to a racket and supporting two arms arranged to limit the play of a spiral characterized in that the two arms project from the base parallel to each other leaving a gap arranged to receive said hairspring, in that the two arms each have a projecting surface which decreases away from the base to limit the size of the end of the key and that the arms comprise each a partially recessed central portion so that the free end of each arm forms a hook along said interstice arranged to receive said hairspring.
  • the invention relates to a watch movement comprising a balance spring-balance resonator and a racking system for adjusting the active length of the hairspring, characterized in that the racking system comprises a racket key according to one of the variants. preceding.
  • the invention relates to a racking system 3 for a movement 1 of a timepiece.
  • the movement 1 watchmaker further comprises a resonator 5 of the type pendulum 6 - spiral 4 mounted on a shaft 7 pivoting between a bridge 8 and a plate (not shown).
  • the racking system 3 is intended to adjust the active length of the hairspring 4. It mainly comprises a racket 9 and a racket key 11.
  • the racket 9 is mounted in its central portion on the deck 8 and supports the racket key 11 to using two blades 10a, 10b. As better visible at the figure 2 , the two blades 10a, 10b serve to lock the racket key 9 between its head 13 and its base 15.
  • the base 15 attached to the racket 9 will allow to adjust, by rotation of the racket 9 on the deck 8, the relative position of the racket key 11 relative to the length of the outer coil 2 of the spiral 4 and, by rotation of the racket key 11 between the blades 10a, 10b, the frolicking of the outer coil 2 of the spiral 4 between the arms 17a, 17b of the racket key 11.
  • the two arms 17a, 17b project from the base 15 parallel to each other leaving a gap 16 arranged to receive the spiral 4 as visible in FIG. figure 2 .
  • the two arms 17a, 17b each have a projecting surface which decreases away from the base 15 in order to limit the bulk of the end of the racket key 11.
  • the two arms 17a, 17b if joined, would form an outer surface close to a truncated cone. Looking at the figure 2 , one realizes that this form of the arms 17a, 17b brings a compactness allowing more space freedom for the balance 6 as, for example, at the level of its weights 12.
  • the arms 17a, 17b each comprise a central portion 18a, 18b partially recessed so that the free end of each arm forms a hook 19a, 19b along the gap 16, that is to say by not being not protruding in gap 16.
  • the racket key 11 has an axis S of symmetry passing through the center of the base 15. This characteristic is particularly desired to avoid having a direction of mounting the racket key 11 between the two arms 10a, 10b.
  • this symmetry offers particular characteristics to the faces Fa, Fb of the arms 17a, 17b along the gap 16.
  • the face Fa of the arm 17a is substantially C-shaped or C inverted. Therefore, the outer coil 2 of the spiral 4 may, advantageously according to the invention, be received not only in the gap 16 but also in the central portions 18a, 18b partially recessed arms 17a, 17b. It is therefore understood that the fretting of the outer turn 2 of the hairspring 4 between the arms 17a, 17b of the racket key 11 will be brought by the stop of the vertical portion of the C or C inverted of the faces Fa, Fb of the arms 17a. , 17b along gap 16.
  • the faces Fa, Fb of the arms 17a, 17b along the gap 16 are preferably flat and parallel.
  • the surfaces V of the faces Fa, Fb of the arms 17a, 17b along the gap 16 which are vis-a-vis are substantially I-shaped.
  • the outer coil 2 of the spiral 4 is trapped in the gap 16 and the central portions 18a, 18b partially recessed from the arms 17a, 17b.
  • the curvature of the outer coil 2 of the spiral 4 extending in the central portions 18a, 18b partially recessed arms 17a, 17b, the hooks 19a, 19b prevent the spiral 4 to be able to exit the gap 16 of the racket key 11 even in case of shocks suffered by the movement.
  • racket key 11 could be of different geometry to adapt to another type of spiral and / or another type of rocker and / or another type of racket and / or another type of bridge.
