  • the invention relates to the field of geometric adjustment settings of timepiece components whose position conditions the chronometric precision of a timepiece.
  • the adjustment of the balance of the balance is of the utmost importance for the accuracy of the oscillator.
  • the adjustment of the balance beam is traditionally done by bending the balance bridge, or by moving the shock absorbers, which is on the one hand difficult to quantify, and on the other hand difficult to reverse in the case of adjustment by deformation. .
  • Another possibility is to integrate one or more adjustment screws under the support (s) of the balance bridges. If the deformation of the bridge is thus avoided, precise identification remains inconvenient, and the specific clearance of the screws is also to be taken into account.
  • the invention consists in replacing the adjustment screws by components in the form of a double, or even triple, ring-shaped staircase (for example 2x180 ° / 3x120 °) smooth or notched.
  • the variant with the use of notched stairs has the advantage of making it possible to feel the number of steps taken, and to quantify the modification value of the play.
  • it is the value of the angle which indicates the value of displacement and modification of the bead.
  • the invention relates to a mechanism for adjusting a clockwork bridge fixed to a structure, according to claim 1.

  • the invention also relates to a timepiece, in particular a watch, comprising at least one such clockwork movement, and / or at least one such clockwork oscillator mechanism, and / or at least one such adjustment mechanism.
  • the invention relates to an adjustment mechanism 10 of a clockwork bridge 200 fixed to a structure 300.
  • the invention is illustrated in the figures, in a particular and non-limiting manner, for the adjustment of a bridge 200, which is a balance bridge, with respect to a watch plate constituting such a structure 300.
  • This adjustment mechanism 10 comprises, coaxial and movable with respect to each other by sliding along a common axis D10 and / or in rotation with respect to this axis D10 which defines the direction of adjustment, and biased towards one another. the other by an elastic return means or pressed against each other by a clamping means, a first component 1 which is arranged to be fixed to the structure 300 or to the bridge 200, and at least one second component 4 which is arranged to be fixed to the bridge 200 or respectively to the structure 300.
  • the first component 1 comprises, on a first annular or circular sector around the axis D10, a first relief 3 or 7 facing a second relief 6 or 8 which the second component 4 comprises on a second sector annular or respectively circular around the same axis D10.
  • This first relief 3 or 7 and this second relief 6 or 8 have a variable cooperation depending on the relative angular position between the first component 1 and the second component 4.
  • Each particular relative angular position defines a particular distance value between reference surfaces S1 , and S2, perpendicular to the axis D10, of the first component 1 and of the second component 4, which are for example their plane ends, opposite to each other, in the non-limiting case of the figures.
  • the arrangement of the first relief 3 or 7 and of the second relief 6 or 8 is intended to allow a sensitive adjustment for the watchmaker who performs the clearance adjustment, and to allow him to go back, which the usual deformation of the bridge does not allow.
  • This sensitive adjustment can be linked to jumps, in particular at the level of passage of notches, or of up / down steps, and / or friction.
  • the figures 5 to 7 illustrate the case where, within the adjustment mechanism 10, the first relief 7 and the second relief 8 each comprise a friction surface capable of maintaining a stable relative angular orientation between the first component 1 and the second component 4 when they are pushed towards each other, in an infinity of possible positions, each relative angular orientation inducing a distance value which is different from the distance values corresponding to the other particular positions.
  • the first component 1 and the second component 4 each comprise a relief 7, 8, turned towards another relief 8, 7, of the other component, these reliefs being arranged to cooperate with each other by friction, but not necessarily being strictly complementary.
  • Each relative angular position between the two components 1 and 4 corresponds to an axial distance H between the reference surfaces S1, S2, particular to the stack formed by this first component and this second component.
  • the reliefs 7 and 8 of the two components 1 and 4 are in a very low pitch helix, on an annular track, each helix terminating in a straight edge 91, 92.
  • Reference marks 9, 90, 900 are made on the external cylindrical diameter that each of the components comprises, a numerical identification, or the like, can also be added; the references 90 and 900 correspond to the location of the fronts 91 and 92: In this example there is a guide of the cylindrical type between two surfaces 2, 5, of the two components 1 and 4 with respect to each other.
  • the reliefs 3 and 6 are arranged so as to provide a range of several different distances H, and preferably obtained in increasing order when the relative rotation between the first component 1 and the second component 4 is made in a single direction of rotation. .
  • At least one relief 3, 6, and more particularly each relief 3, 6, is of the helical staircase type, with a sloping surface allowing the gear change in both directions of rotation; each step can be substantially flat, or even hollow, as on the figures 2 to 4 where each level corresponds to a dihedron guaranteeing good adjustment stability, and preventing maladjustment under the effect of vibrations or shocks during the life of the watch.
  • FIGS. 2 to 4 illustrate the case where, within the adjustment mechanism 10, the first relief 3 and the second relief 6 are arranged to guide the first component 1 and the second component 4 in an additional relative rotation towards a stable position among a finite number of positions stable equilibrium when they are pushed towards each other, where each stable position corresponds to a single eigenvalue of distance among a finite number of possible distance values between said reference surfaces.
  • These reliefs 3 and 6 are not necessarily complementary, and are arranged to take with each other a certain number of combinations of discrete positions, each resulting in a particular axial distance H between the reference surfaces S1 and S2 of the stack formed by this first component 1 and this second component 4, each of the combinations corresponding to a different distance.
  • Marks 90, 900 are made on the external cylindrical diameter that each of the components comprises, a numerical marking, or the like, can also be added:
  • the figure 4 shows, in the lower part, a first female ridge 33 of a first hollow dihedron corresponding to a first stair step, a slope leads to a high point formed by a male ridge 30 constituting a hard point to cross during the change of setting , a second dihedral comprises a second female ridge 35, delimited by two oblique faces 31 and 32, this second female ridge 35 is at a latitude different from that of the first female ridge 33, and so on.
  • the number of adjustment positions can be further multiplied with a first component 1 and a second component 4 having different numbers of edges, and in particular prime numbers between them.
