Definitions

  • the invention also relates to a clock escapement mechanism comprising at least one such assembly.
  • the invention also relates to a watch movement comprising at least one such escape mechanism.
  • the invention also relates to a timepiece comprising at least one such movement.
  • the invention relates to the field of clockwork escapement mechanisms comprising a spiral spring.
  • the stud constituting the external attachment point of the spiral spring, is clipped on a bolt carrier which is a stamped flat piece.
  • the stud On high-end creations, the stud is screwed into a stud holder which is a machined component.
  • the fixing screw then works between his foot and his nets. The head is never blocked, resulting in regular breakages, following the torsional forces experienced when the foot is blocked on the peak, and when the operator continues to screw.
  • the document DE 20 2010 014253 U1 in the name of DAMASKO describes a peak with radial adjustment relative to the rooster.
  • the axially tapped stud cooperates with a cylindrical screw, the head of which circulates in a milled oblong groove.
  • the document EP 2 290 477 A1 in the name of GLASHÜTTE UHRENBETRIEB describes a bolt carrier which comprises a thread for fixing the bolt holding the bolt, which cooperates with a recess of this bolt, on a part of the thickness thereof.
  • the invention proposes to create a modified stud, in order to correct the use of the screw, so that it can work normally, by elastic deformation, between his head and his nets. This is to reduce the risk of breakage, while maintaining the high-end structure of a bolt carrier.
  • the invention relates to a holding or supporting assembly of a spiral clock spring according to claim 1.
  • the invention also relates to a clock escapement mechanism comprising at least one such assembly.
  • the invention also relates to a watch movement comprising at least one such escape mechanism.
  • the invention also relates to a timepiece comprising at least one such movement, characterized in that it is a watch.
  • the invention relates to an assembly 20 for holding or supporting a spiral spring 21 of watchmaking, comprising a stud 1 and a stud holder 2.
  • the stud 1 comprises at least one orientation surface 7 defining a direction of support or support of such a spiral spring 21.
  • the figure 1 illustrates the prior art, with a stud 1 housed in a bore 3 of the bolt carrier 2, and a screw 5 engaged in a tapping 21 of the bolt carrier 2 and bearing on the bolt 1 at a side face .
  • this at least one screw 5 passes through the stud 1 for its holding in the indexed and locking position.
  • the stud 1 comprises at least one tapping 8 cooperating with this at least one screw 5.
  • This tapping 8 constitutes the orientation surface 7.
  • the screw head 51 comes to rest on the first bearing face 110 of the stud holder 2.
  • the screw 5 is used in a conventional manner, by making its threads work by elastic deformation. Piton 1 is no longer pushed against the bolt carrier 2 as in the prior art, but it is pulled towards the bolt carrier 2 by the screw 5.
  • the orientation is given by the screw head 51, which determines the orientation of the screw 5 and thus the tapping 8 of the pin, which constitutes the orientation surface 7 of the pin 1 for the maintenance of the spiral spring 21.
  • the bolt carrier 2 may have a clearance in order to adjust the spiral flat by loosening the screw.
  • watchmakers are always careful to position the hairspring so that it is as flat as possible. If the attachment point on the peak is, for example, lower than the point of attachment on the balance shaft, the spiral will tend to take an umbrella shape. To correct this phenomenon, the watchmaker loosens the bolt and raises the bolt until the two attachment points are at the same height, and the hairspring is thus flat. But this setting is only possible in the case where the bolt can move in the piton door.In the example of the figure 5 the piton can only move downwards; in this case, the nominal position of the stud should be chosen so that the screw is centered in the opening to allow correction in both directions.
  • the hole crossing the piton prevents the displacement. Adjustment is not possible in a cylindrical hole version; in a variant, an oblong allows this height adjustment.
  • the screw 5 is unique, as well as the tapping 8 of the piton 1.
  • this at least a second housing 12 is oblong in a direction perpendicular to that of the at least one screw 5, for the height adjustment of said pin 1.
  • this at least one second housing 12 is dimensioned larger than the outer diameter of the thread of this at least one screw 5, in particular under oblong shape, with a clearance J for adjusting the height of the peak 1.
  • the screw head 51 is of a diameter sized to remain in abutment on the periphery of the second housing 12 in any adjustment position of the peak 1.
  • the screw 5 is unique, as well as the second housing 12 of the piton 1.
  • the invention also relates to a horological escapement mechanism comprising at least one such assembly 20.
  • the invention also relates to a watch movement 40 comprising at least one such exhaust mechanism 30.
  • the invention also relates to a timepiece 50 comprising at least one such movement 40.
  • this piece 50 is a watch.
