Definitions

  • the present invention aims to eliminate or at least greatly reduce the disadvantages of non-concentric displacements of the flat hairspring at its extensions or contractions.
  • This invention relates to the movements mechanical timepieces and more particularly those used in wristwatches.
  • the precision of the mechanical clockwork movement depends on the balance-spring assembly which constitutes the regulatory body.
  • This set is a mechanical resonator that oscillates at a frequency of for example 4 Hz.
  • FIGS. 1, 2 and 3 represent as an example a set Spiral balance of a traditional clockwork movement partially represented.
  • Figure 1 is a perspective view from above, Figure 2 a section and Figure 3 a view of the whole sprung balance.
  • a curve 10 usually called the Breguet curve above the general plane of the hairspring and for the case where he does not have enough height he is satisfied with a flat hairspring without particular curve and therefore applies the theories of the point of attachment.
  • These theories partially correct the defects induced during oscillations of the flat hairspring; however, to achieve a correct result it is necessary to implement complex and costly pairing operations between the balance and the hairspring, in order to place the point of attachment of the latter in a specific place.
  • This section different straight is obtained especially by folding the blade on itself in the direction of its length, in order to obtain, at the place of the folded part, a rigidity greater than that of the rest of the hairspring.
  • the document proposes two folded parts, one located near the ferrule to force the inner half of the turns to develop concentrically and the other being located near the peak to force this time the outer half of the turns to also develop concentrically.
  • the proposals of this patent are interesting and go in the right direction, but it will be understood that problems with folding makes this unworkable solution in the framework of a traditional production of spirals metal strapped and heat-treated together.
  • the present invention relates to a hairspring for mechanical watch movement characterized in that it is provided with a peripheral outer curve located in the same plane and that the rigidity of this curve is such that the central part of the whole thus constituted develops concentrically during its oscillations.
  • Figure 9 shows schematically this set in plan. It consists of a curve outside 10 going from point 15 to the peak 8 which envelops the central portion 14 on an angle ⁇ more or less equal to 270 °.
  • This curve 10 has 3 elbows 16, 17 and 18 which are similar to those existing on the traditional Breguet spiral curve designated at the Figure 7 in 11, 12 and 13. These elbows are useful to the specialist who can once all balance-spiral placed in the movement to modify them and thus obtain the best centering possible turns of the central part of the whole.
  • the thickness of this curve is reinforced in the zones 19, 20 and 21.
  • FIG. 10 shows, according to the above, an embodiment for which the curve is made separately from the central part, both elements being fixed to each other in point 15 by gluing or any other means likely to achieve this fixation.
