  • the invention relates to a watch comprising at least one such mechanical clockwork movement.
  • the invention relates to the field of clockwork mechanisms comprising spiral springs of micro-machinable material, and more particularly the exhaust mechanisms.
  • the fine adjustment is strongly limited because the hairspring does not include a control system independent of the average frequency and isochronism, which can be used after assembly .
  • the isochronism slope is modified by a modification of the active length, the average frequency of the corresponding sprung balance assembly is strongly modified, and a correction of the pendulum screws is generally not sufficient to compensate for this defect.

  • Each stage 10 is made of micro-machinable material.
  • this spiral 1 is monobloc.

  • each stage 10 then comprises angular indexing means arranged to cooperate in a complementary manner with complementary angular indexing means, which comprise the other stages, to form together a spiral 1 compound, of fixed geometry and perfectly reproducible.
  • a particular application illustrated by the Figures 5 and 6 , comprises three spirals, fixed to the ferrule at non-aligned points, for example at 120 ° from each other, and offset in height.
  • each stage 10, 10A, 10B has, at its respective outer end 30A, here 30A, 30B, its own fixing means 40 to a pin, here 40A, 40B, which are independent of those of said other stages.
  • the invention is usable both in an environment with a single peak 3, with which cooperate all the layers in superposition, in an environment where each floor 10 corresponds a particular peak. It's this variant that is illustrated on the Figures 9 and 10 a peg 3A, for example integral with a bridge, cooperates with an upper stage 10A of the hairspring 1, and another peg 3B, for example integral with a plate, cooperates with a lower stage 10B of the hairspring 1.

  • these discrete positions correspond to recesses 6, in a U shape or the like, each designed to hold a stud 3.
  • the fabrication of micro-machinable material allows more complex geometries, in particular with omega-shaped or similar clamping housings between deformable flexible walls during the relative introduction of the stud relative to the housing chosen by the adjuster or by an automaton determining the optimum adjustment position, these walls being then arranged to ensure a firm hold on the peak after installation.
  • the position adjusting means 50 are arranged, for each stage 10A / B / C, on a scale of one side of the respective spring strand, and are essentially designed for a modification of the effective length of the stage concerned, and its rigidity.
  • the adjustment means offer, on each floor, the possibility of positioning a pin in a matrix-type structure, in a sort of grid, or network, with cells 601A to 605A or 601B to 605B, arranged in two rows substantially parallel, on both sides of the strand of the concerned spring: it is then possible to play both on the length, and on the radial position to choose the point of attachment.
  • More complex implementations, with more rows and columns of matrix, are easily achievable thanks to the use of micro-machinable materials, the only limit being that of the accessibility to the peak and the passage of the installation tool .

It is possible to proceed, at the end of the adjustment operations, to the fastening of the housing 6 with the pin 3, for example by gluing.
  • the U-shaped profile, or the like comprises lugs enabling the U to be clipped onto the stud 3, which then makes it possible to avoid sticking.
  • the fastening means 40 and the adjustment means in position 50 thus together constitute intrinsic means for correcting the isochronism of the hairspring 1.
  • the Figures 7 to 10 also illustrate a particular variant, according to which the fixing means 40 are of variable rigidity according to the position of the adjustment means in position 50.
  • the adjustment means in position 50 of a given stage 10 comprise, in this variant, a plurality of elastic multi-arm assemblies 70, which also define these discrete position adjustment positions 60 exposed above, and which support the housings 6.
  • the elastic multi-arms 70 are of different stiffness between them.
  • These elastic multi-arms 70 are illustrated here with parallel flexible blades, which is authorized by the method of producing the spiral 1. They are arranged in groups of decreasing or increasing rigidity, with three blades 701A, 704A, 701B, and then two blades 702A, 702B, up to a blade 703A, 703B, in the particular and non-limiting case of the figures.
  • the stiffness of the outermost segment of each stage 10 can be adjusted as desired, and it is therefore possible to act on the variable rigidity of the entire spiral 1.
  • the stiffness of these elastic arms may, depending on the case, be chosen decreasing from the outer end 30 of the stage concerned as in the case of the figures, or conversely, or other.
  • the adjustment means in position 50 of a given stage 10 may then comprise a plurality of elastic multi-arm assemblies 70, which are likewise stiff between them.
  • the elastic multi-arm assemblies 70 each comprise at least one internal attachment point on a first inner range, and at least one external attachment point on a second outer range, further from the pivot axis of the balance 1 than the first range, which allows very different positioning of the piton concerned with respect to this floor.

  • At least two stages 10 comprise opposing coil direction springs. This is the case of all figures.
  • the total rigidity of all the stages 10 wound in a first direction is equal to the total rigidity of all the stages 10 wound in a second direction opposite to this first direction.
  • the hairspring 1 once the hairspring 1 is assembled, it is possible to modify the active fastening position, even when the hairspring is already assembled with a balance and in a movement.
  • FIGS. 5 and 6 illustrate an advantageous variant with three superimposed spiral stages 10A, 10B, 10C.
  • each has an inner end 20A, 20B, 20C, and an outer end 30A, 30B, 30C, and fastening means, which comprise position adjustment means, not listed in the figures to not weigh them down.
  • these position adjustment means comprise housings 6 which are here U-shaped profiles, arranged to cooperate with a stud 3 of rectangular or square section, this example section piton and shape profiles being in no way limiting.
  • the stud 3 is straight, parallel to the common axis of the spiral stages. This version is very easy to build, and therefore very economical.

  • the figure 5 shows a particular hooking position where the housings 602A, 602B and 602C cooperate with a common pin 3.
  • the adjustment changes are easy, because each spiral spring can be conveniently compressed to allow a change of attachment position to piton considered.
  • this particular arrangement allows adjustment on one of the stages independently of the settings on the other stages, conveniently enough for the operator performing the adjustment.
  • the figure 11 illustrates the preferred case where the resultant forces brought to the peak is zero, this is the case of a three-stage hairspring, the upper 10A and the lower 10C being identical and with the same winding direction, and each of stiffness half of the middle stage 10B wound in the opposite direction.
  • the efforts FA and FC are exerted on both sides of the FB effort of opposite direction, substantially in a plane tangential to the ends of these springs, and parallel to the common axis of the spirals, the resulting torque is thus minimized or zero.
  • This configuration of the invention makes it possible to increase the rigidity of a spiral stage, consequently reducing that of the other stages of spirals, or vice versa. And, in this particular and preferred case where the stiffness of the two most flexible spirals is half of the stiffness of the stiffest hairspring, the average frequency remains the same, for all configurations of fixing the spiral stages to the pin 3.
  • the rigidity of the two stages 10A and 10B of the illustrated variants changes in opposite manner: the spring of a stage becomes more rigid, while that the other becomes less rigid.
  • the geometry of the two springs can therefore be defined and adjusted, so that the resulting total stiffness, and therefore the oscillation frequency of the sprung balance constituted by a spiral 1 according to the invention, changes little during the procedure of adjustment of the isochronism slope.
  • the usual adjustment of the balance screws always makes it possible to adjust the average frequency of the balance sprung-balance assembly.
  • the modification of the isochronism slope as a function of the fixing position remains important, and makes it possible to correct manufacturing or assembly defects, for example gluing.
  • the invention also relates to a sprung-balance assembly 100, comprising a balance 2 coupled with at least one such spiral 1.
  • the invention also relates to an escapement mechanism 200, comprising at least one such spring-balance assembly 100, and comprising at least one pin 3 for the attachment in position of the outer end 30 of at least one said stage 10 .

  • the escapement mechanism 200 comprises at least one pin 3 whose position is movable is adjustable, for attachment in position of the outer end 30 of at least one stage 10.
