Definitions

  • the invention relates to an elastic holding member for fixing a watch component to support elements of different types such as a balance shaft or even a false axis.
  • the invention also relates to an elastic holding member - watch component assembly and assemblies comprising such an assembly and a support element.
  • the invention finally relates to a watch movement comprising at least one of these assemblies as well as to a timepiece comprising such a movement.
  • elastic holding members such as watch collets, which participate in assemblies of hairsprings on balance shafts or axles of regulating members, such as resonators of watch movements, by elastic tightening.
  • Such hairsprings are each conventionally wound around a hairspring shaft, being provided with a collet at their inner end.
  • This collet comprises an opening, the inner face of which comprises holding parts which are arranged to cooperate with a shaft of revolution around said hairspring shaft, contributing to the centering of said hairspring on such a shaft.
  • the collet of a given hairspring is then driven onto a false axis of circular cross-section which helps to ensure that it is held in an angular and vertical position.
  • the diameter of this false axis is defined according to the diameter of the opening of the hairspring collet, so that the holding of this collet in an angular and vertical position, when measuring the torque of the hairspring, is obtained by tightening this collet on this false axis.
  • Such tightening which results from the elastic deformation of the collet, has a value defined according to the diameter of the false axis.
  • the hairspring collet is then separated/driven out of the false axis with a view to its assembly by driving onto the balance shaft so that the holding parts of the collet cooperate with this balance shaft in order to ensure elastic tightening.
  • such a filing operation can be the cause of "product defects" because the collet can break/become chipped during multiple and repetitive stresses related to its driving in, driving out on/from the false axis and then “redriving" on the balance shaft, or during the operation of the resonator in which it is included, in particular when setting in motion.
  • the tightening carried out between the false axis and the collet causes shearing forces which can damage this collet by generating micro-breaks at the level of at least one edge of this collet.
  • the aim of the present invention is to overcome all or part of the drawbacks mentioned above by proposing an elastic holding member comprising several specific holding parts, each designed to cooperate exclusively with a given type of support element and in particular with the peripheral wall of this support element when mounting this member on the latter.
  • the invention relates to an elastic holding member according to claim 1 for fixing a watch component on support elements of different cross-section, comprising an opening in which each support element is capable of being inserted, the holding member comprising structural elements together forming the body of this holding member and contributing to ensuring mounting of each support element in said opening, each of these structural elements comprising a first structural sub-element and a second structural sub-element, the first structural sub-element comprising a volume of material greater than the volume of material constituting the second structural sub-element, the holding member comprising a connecting portion ensuring mounting in the holding member of each of said support elements, said portion being defined on an inner face of said first structural sub-element.

  • the connecting portions of the first structural sub-elements of such a holding member make it possible to ensure mounting of this member on the false axis by performing a fitting and coupling of this holding member with this false axis, without this mounting requiring a driving operation as is the case in the prior art.
  • This fitting provides for the installation of this holding member in an angular and vertical position on the false axis, in particular when measuring the torque of a hairspring, without elastic tightening, i.e. without deformation of the structural elements or without deformation of this holding member.
  • a coupling between the holding member and the false axis necessary for carrying out the sorting operation is obtained without elastic clamping, thanks in particular to the complementarity of their shape which thus allows cooperation between the latter when they are driven in a rotational movement during the carrying out of the sorting operation, and also thanks to the distribution of the volume/quantity of material between the first and second structural sub-elements of each structural element constituting this holding member. It is therefore understood that during the carrying out of the sorting operation, the holding member is no longer stressed by shear forces which can damage it by generating micro-breaks at the level of its structure.
