Definitions

  • the present invention relates to a spiral or spiral spring clock, more particularly a spiral for a balance-spiral system of a movement mechanical watchmaking.
  • the hairspring is connected by its inner end to a ferrule chased on the tree of pendulum and by its outer end to a peak attached to the cock of the movement.
  • the fixing of the outer end of the spiral to the piton is carried out by placing and blocking by means of a pin or by bonding said outer end into a piton hole provided for this purpose.
  • This operation may in practice prove to be difficult to achieve, especially in cases where, for technical reasons or the piton is not adjustable in height.
  • a manual operation of deformation of the outer end of the spiral is often necessary to position this outer end in the piton hole after the hairspring has been driven off the balance shaft, because the Piton hole is rarely found in its ideal position relative to the ferrule.
  • the present invention aims to remedy the aforementioned drawbacks and proposes, for this purpose, a hairspring as defined in appended claim 1, particular embodiments of this spiral being defined in the dependent claims, as well as a balance spring device and a clockwork incorporating it.
  • a hairspring 1 of the flat spiral type comprises an end 10 attached to a ferrule 2 driven on the shaft 3 of a pendulum (no shown) and an outer end 11 attached to a fastening element 4, also called "piton", of cylindrical shape with circular section.
  • the piton 4 is attached to the cock (not shown) of the movement.
  • the spiral 1, more precisely the spiral-ferrule assembly 1-2, is preferably made in one piece, for example in silicon.
  • the outer end 11 of the hairspring 1 is thicker than the rest of the blade forming the hairspring 1 and comprises a rigid portion 12 and a flexible portion 13 together defining an oblong opening 14.
  • the oblong opening 14 is oriented substantially in the winding direction of the hairspring, more specifically in a circumferential direction relative to the center of the hairspring.
  • Part 12 is made rigid by its thickness e1, greater than the thickness e2 of the part 13.
  • the flexible portion 13 is located radially beyond the rigid part 12, that is to say that the flexible part 13 constitutes a part outer end 11 while the rigid part 12 constitutes a part interior of this end 11.
  • the rigid parts 12 and flexible 13 could be reversed or even the two parts 12, 13 could be Flexible.
  • the opening 14 can deform elastically to receive and tighten the pin 4 and thereby fix the outer end 11 of the spiral audit piton 4.
  • This open end 15 and the oblong shape of the opening 14 give the latter sufficient deformability for easy hunting of the end 11 on the peak 4.
  • the opening 14 also has near its end open a formation 17 of piton 4.
  • This formation 17 is for example a recess formed in the flexible portion 12, as illustrated.
  • this formation 17 has preferably a shape such as to allow contact only in a number determined points, typically three points 18a, 18b, 18c, between the end 11 of the spiral 1 and the peak 4.
  • the dimensions of the opening 14 are determined so that the maximum stress exerted by the pin 4 on the outer end 11 of the hairspring 1 is less than the elastic limit of the material forming the spiral 1, that the opening 14 accommodates manufacturing tolerances of piton 4 and that the holding of the outer end 11 on the stud 4 is adequate.
  • flank 19 of the opening 14 is machined cleanly to be rendered as perpendicular as possible to the plane of the hairspring 1, in order to guarantee a good perpendicularity between the hairspring 1 and the bolt 4.
  • FIG. 2 illustrates a hairspring 1 'according to a second embodiment of the invention, in which, unlike the hairspring 1 according to the first embodiment of embodiment, the contour of the oblong opening 14 'of the outer end 11' in the plane of the spiral is closed.
  • This contour is defined by two flexible parts opposed elongated members 12a ', 12b' oriented substantially in the direction winding of the spiral 1 'and two opposite rigid parts 13a', 13b 'connecting between they flexible parts 12a ', 12b'.
  • the flexible portions 12a ', 12b' are straight in rest position.
  • the hairspring 1 ' according to this second embodiment of the invention is particularly suitable for applications in which a reduced radial size of the end outer of the hairspring is desired. It should be noted however that in a variant, the hairspring 1 ' could be modified so that one of the parts 12a ', 12b' is rigid and possibly include piton positioning training.
  • the present invention as described above has many advantages.
  • it allows an implementation that is both easy and precise the fixation of the outer end of the spiral to the piton avoiding on the one hand the use of auxiliary fastening means such as pin, glue, etc. and in facilitating the positioning of the hairspring relative to the piton.
  • auxiliary fastening means such as pin, glue, etc.
  • the height of the outer end of the spiral on the peak is adjustable, which allows when starting (mounting the balance-balance system in the movement) to adjust the flat of the hairspring without having to deform said outer end.
