  • this retaining member 1a, 1b, 1c can be included in an assembly 120 elastic retaining member - timepiece component.
  • Such an assembly 120 is intended to be arranged in a timepiece movement 110 of a timepiece 100 visible on the figure 3 , and also intended to be mounted on a support element 3.
  • Such an assembly 120 can be a single piece and be made of a “fragile” material similar to that of the holding member 1. It will be noted that in a variant of this assembly 120, only the elastic retaining member 1a, 1b, 1c can be made of such a so-called “fragile” material, the timepiece component 2 then being made of another material.
  • This assembly 120 can form part of an assembly 130 for the watch movement 110.
  • Such an assembly 130 has been devised here for applications in the watchmaking field.
  • this assembly 130 can perfectly well be implemented in other fields such as aeronautics, jewelry, or even the automobile.
  • Such a holding member 1a, 1b, 1c is preferably a single piece which comprises an upper face and a lower face which are preferably planar, which are both respectively included in first and second planes P1 and P2.
  • This member 1a, 1b, 1c also has a thickness which extends from the upper face to the lower face.
  • Such a retaining member 1a, 1b, 1c also comprises a rigid portion 7 provided with an inner face 6. This rigid portion 7 corresponds to the part of the retaining member 1a, 1b, 1c which comprises the largest volume. of matter.
  • the retaining member 1a, 1b, 1c may also include an outer face or outer peripheral wall, in particular when it is a ferrule which is in particular intended to be connected to the timepiece component 2 by means of at least one attachment point arranged in this outer face.
  • the holding member 1 may be integral with the timepiece component 2 when the latter is a wheel visible on the figures 1 and 2 .
  • this retaining member 1a, 1b, 1c the inner face 6 participates in defining a volume 5 in which are arranged at least three deformable arms 4 provided with free ends 9.
  • this member 1a, 1b , 1c comprises six arms 4 shown on the figures 1 and 2 . It will be noted that this volume 5 is only partially occupied by these deformable arms 4. Such arms 4 are included in the inner face 6 and extend radially from this face 6 towards a central axis A of said holding member 1a, 1b. , 1 C.
  • these deformable arms 4 consist essentially of a main part 8 full / non-perforated, comprising a quantity of material which decreases regularly in a direction extending from this inner face 6 towards the central axis A.
  • the deformable arms 4 consist essentially of a main part 8 perforated, with a perforation 14 more important in the third variant than that 13 of the second variant.
  • the quantity of material also decreases regularly in a direction extending from this inner face 6 towards the central axis A.
  • the quantity of material in the main part 8 of each arm 4 of the third variant is less than that of each arm 4 of the second and even less than that of each arm 4 of the first variant.
  • each of these arms 4 preferably has an essentially trapezoidal shape.
  • These deformable arms 4 each comprise two ends, a first end connected to the inner face 6 of the retaining member 1a, 1b, 1c and a second end which is the free end 9 visible on the figure 1 .
  • This free end 9 comprises a contact face 10 having a shape configured / adapted to cooperate with a mounting zone of the support element 3 intended to cooperate with this contact face 10.
  • the contact face 10 has a compatible shape able to match this cylindrical shape by being for example a curved contact face 10.
  • the free ends 9 of these arms 4 together define an opening 12 into which said support element 3 can be inserted.
  • This opening 12 defines a volume in the holding member 1a, 1b, 1c which is smaller than that of the mounting zone included in one end of the support element 3 which is intended to be arranged there.
  • the mounting zone of the support element 3 comprises all or part of the contact portions 13 of this support element 3 with the holding member 1a, 1b, 1c which are defined on a peripheral wall of this support element 3 and which are intended in particular to cooperate with the arms 4 of this retaining member 1a, 1b, 1c.
  • this support element 3 comprises at least as many portions 10 as the holding member 1a, 1b, 1c comprises arms 4.

  • each of these arms 4 when subjected to a stress induced by the support element 3 as will be seen subsequently, is capable of being deformed by passing from a rest configuration to a constrained configuration.
  • the arrangement of the deformable arms 4 in the holding member 1a, 1b, 1c allows, during insertion with clamping, a deformation of each arm 4 making it possible to accommodate the deformation of the holding member 1a, 1b , 1c with the geometry of the mounting area of the support element 3.
  • this mounting area which comprises the contact portions 13 of this support element 3 is preferably arranged coaxially with the opening 12 and this, around the central axis A which is common to this mounting zone and to this opening 12 of the 'retaining member 1. Such an arrangement around this common axis A participates in an indexing of this mounting zone relative to the opening 12 during this insertion.
  • Such a deformation contributes in particular to the holding member 1a, 1b, 1c to store a large quantity of elastic energy which contributes to giving it a substantial holding torque, in particular allowing optimum holding by elastic clamping in compression.
  • an elastic member 1a, 1b, 1c allows the clamping force to be increased significantly in comparison with the elastic members of the state of the art, in fact this clamping force is here approximately twice as large as that of the components of the state of the art for the same configuration.
