  • the invention also relates to a notching system comprising such a spring.
  • the invention also relates to a timepiece case or a timepiece movement comprising such a spring or such a notching system.
  • the invention also relates to a timepiece comprising such a case or such a movement or such a notching system or such a spring.
  • the horological literature mentions numerous notching devices, in particular notched or angularly indexed rotating bezels.
  • the document EP2624076 discloses a unidirectional rotating bezel whose angular indexing is implemented by means of a single first notching element in the form of a pawl returned by a return spring against an edge toothing in a direction parallel to the axis of rotation of said bezel.
  • This spring is presented here in the form of a helical spring.
  • the document EP0686897 discloses, meanwhile, a bidirectional rotating bezel whose angular indexing is implemented by a wire spring in the form of a single elastic arm. This is articulated at a first end on the annular seat of a middle part, while its free end forms a single first notching element provided to cooperate with an internal toothing formed on the bezel. The angular indexing of the bezel is thus operated by a single first notching element formed on the spring.
  • the wire spring described in the document EP0686897 has the particularity of being shaped so as to generate substantially equal torques regardless of the direction of rotation of the bezel. To do this, this has in particular a concave or substantially concave shape when it is seen from the axis of rotation of the bezel.
  • the device described in the document EP1431845 further proposes to improve such a bidirectional notched rotating bezel by ensuring that the forces are balanced with respect to the axis of rotation of said bezel, which contributes to the pleasant feeling that one experiences when handling it.
  • this device implements a spring in the form of a closed loop centered on the axis of rotation of the bezel.
  • the spring comprises elastic arms each provided with a first notching element intended to cooperate with second notching means of a notching ring.
  • This spring comprises first connecting means shaped and arranged at each of the first notching means so that the latter can move radially relative to the axis of rotation of the bezel and thus cooperate with the second notching means.
  • the document EP3543800 also discloses a spring in the form of a closed loop taking part in a notching system for a uni- or bidirectional rotating bezel.
  • This spring has the particularity of comprising elastic arms each interconnected at their longitudinal ends by first connecting means in the form of indentations.
  • each elastic arm comprises a first notching element arranged equidistant from two notches, which is shaped so as to cooperate with second notching means of a notching ring.
  • the first and second notching means here specifically take the form of teeth.
  • the spring is embedded in the bezel at the level of its indentations, the latter cooperating with lugs arranged on said bezel.
  • the arms of the spring are caused to deform elastically opposite these embedding connections. More particularly, these arms are caused to deform elastically simultaneously and in synchrony.
