  • the elastic holding member is then able to support a significant elastic tightening and therefore to store a significant quantity of elastic energy when it is constrained in order to restore a significant holding torque, in particular thanks to a significant rigidity of this elastic holding member induced in particular by substantial volumes (or quantities) of material constituting its rigid arms which include the internal and external structures. It will be noted that these large volumes of material are more precisely included in the contact zones which are placed under load (or under stress) during insertion of the support element into this holding member.

  • the elastic holding member 1 can be made of such a so-called “fragile” material, the timepiece component 2 then being made of another material.
  • This assembly 120 can be part of an assembly 130 for the watch movement 110, by being fixed to the support element 3 for example by elastic clamping. It should be noted that this assembly 130 was designed for applications in the watchmaking field. However, the invention can be perfectly implemented in other fields such as aeronautics, jewelry, or even automobiles.
  • Such a holding member 1 comprises an upper face and a lower face 12, preferably flat, included respectively in first and second planes P1 and P2 visible on the figure 2 , as well as external and internal structures 4a, 4b.

  • Concerning the internal structure 4b it has a non-triangular shape.
  • This internal structure 4b which comprises the internal peripheral wall of this holding member 1, participates in defining an opening 5 of such a holding member 1 in which the support element 3 is intended to be inserted.
  • This opening 5 defines a volume in the holding member 1 which is less than that of a connecting part of one end of the support element 3 which is intended to be arranged there.

  • Such a contact zone 8 is defined in the interior face of each arm rigid 6 extending substantially over all or part of the thickness of the holding member 1. It will be noted that the convex contact zones 8 of the rigid arms 6 are provided in particular to cooperate with the convex contact portions 10 according to a convex-convex type contact configuration in which configuration where the convex surface of each contact zone 8 cooperates with the corresponding portion of convex shape of the support element 3. Let us specify here that this convex shape of each contact portion 10 is assessed relative to the convex surface of each corresponding contact zone 8 with respect to which this portion 10 is arranged.
  • this contact zone 8 in the interior face of each rigid arm 6 makes it possible to create a contact pressure between the holding member 1 and the support element 3 during the production of a mechanical connection between them, while significantly reducing the intensity of stresses at this contact zone 8 and the corresponding contact portion 10 of the support element 3 during assembly and/or fixing of this holding member 1 with the support element 3, which constraints being likely to damage the holding member 1 by the appearance of breaks/breakages or even cracks.

  • this gap E is a maximum gap E1 when it is defined between parts of internal and external peripheral walls included in each rigid arm 6, i.e. the maximum distance E1 present between the interior and exterior faces of this rigid arm 6.

  • this distance E is a minimum distance E2 when it is defined between parts of the external and internal peripheral walls included in the elastic arms 7, i.e. the minimum distance E2 present between the faces interior and exterior of this elastic arm 7.
  • Such a configuration of the rigid and elastic arms 6, 7 allows the holding member 1 to store a greater quantity of elastic energy for the same tightening in comparison with the holding members of the state of the art. Such an amount of energy elastic stored in the holding member 1 then makes it possible to obtain a greater holding torque of the holding member on the support element 3 in the assembly 130 of the holding member - component assembly 120. watchmaking with this support element 3.

  • the end of the support element is presented at the entrance to the opening 5 defined in the lower face 12 of the holding member 1 in anticipation of the introduction of the connecting part of this support element 3 into the volume defined in this opening 5.
  • This step 13 comprises a sub-step 14 of elastic deformation of the holding member 1 in particular of a central zone of this holding member 1 comprising said opening 5 resulting from the application of a contact force on the contact zones 8 of the rigid arms 6 by the contact portions 10 of the peripheral wall 13 of the connecting part of the support element 3.
