Definitions

  • the invention relates to a regulating member for a watch comprising a fixed structure extending substantially perpendicular to an axial direction, said regulating member comprising a regulating member with a balance arranged to pivot about a balance axis.
  • the invention also relates to a watch comprising such a regulating member.
  • the invention relates to the field of regulating members for watches.
  • the invention aims to further improve the chronometric properties of the regulating organs, in particular but not limited to whirlwinds or carousels, by adopting particular geometries of the pivot axes of the various mobiles, in combination with the adoption of means of magnetic pivoting, at least at the level of the inertial mass of the resonator, in particular a pendulum.
  • the invention relates to a regulating member for a watch, according to claim 1.
  • the invention also relates to a watch comprising such a regulating member.
  • the figure 1 presents, very schematically, a watch 1000, which has a fixed structure 100, typically composed of a plate and bridges.
  • This fixed structure 100 conventionally extends substantially along a plane intended to tangent the wrist of a user for a wristwatch, or to tangent the body or a garment of the user in the case of a pocket watch.
  • This fixed structure 100 extends substantially perpendicular to an axial direction D0.
  • this axial direction D0 is that of the axes of the displays such as needles or discs, and it is also the direction of most of the mobiles contained in a watch movement.
  • the figure 1 has only part of the regulating member, in this case an inertial mass, here a balance 1, which is returned to a rest position by elastic return means not shown, such as a spiral spring or flexible blades.
  • This pendulum 1 pivots around a pendulum axis D1, which here is parallel, or substantially parallel, to the axial direction D0.
  • substantially parallel here is meant that the axial direction D0 and the direction of the pendulum axis D1, reported at the same point, are included in a cone with a total angle at the top less than 10 °.
  • the figure 2 presents the typical chronometric properties of a resonator with magnetic pivoting of the balance.
  • the standard positions VB, VH, VD, VG, HH and HB are shown on the figure 1 , with reference to an XYZ trihedron whose Z axis corresponds to the gravity field.
  • This figure 2 shows relatively small gait differences between the different chronometric positions, with a maximum amplitude of approximately 7 seconds per day, and with a small drift during the disarming time of the barrel, of the order of 3 seconds per day (included in the previous 7 seconds per day). These values represent significant progress compared to a traditional pivot resonator.
  • We can see that the greatest gait deviations logically correspond to the measurements made according to the direction of the gravity field, HH and HB.
  • the other running values are very close to each other, and converge towards a low common value, between 1 second per day and two seconds per day, towards the end of disarming the barrel.
  • the figure 3 indicates the main elements of the architecture of this regulating organ mechanism 30, with the shaft 2 of the pendulum 1 pivoted in cooperation with magnets 3 and 5 housed at the level of solid elements 4 and 6 of the structure 100.
  • the balance 1 conventionally comprises a twill 9, supporting micrometric adjustment members not shown.
  • the pendulum 1 comprises plates arranged to cooperate with the fork and the stinger of a retainer 7, in particular an anchor, pivotally mounted around an anchor axis DA; this anchor conventionally cooperates with an exhaust mobile 8, here an escape wheel, pivotally mounted around an exhaust axis DE.
  • the vertical positions can be adjusted precisely, by adjusting the balance imbalance, in particular by the adjustment screws on the clamp.
  • the steps in these positions are therefore grouped in a relatively limited interval ( ⁇ 2 seconds / day, even ⁇ 1 second / day).
  • the "horizontal high HH" and “horizontal low HB” positions are practically not adjustable. Indeed, in one of these positions, the weight of the balance adds to the axial magnetic force while in the other position, the weight subtracts from the axial magnetic force. This results in a slight difference in gait between these two positions.
  • the chronometric assessment is therefore as follows: grouped vertical steps, and the HH and HB positions are discarded.
  • the figure 5 presents the typical chronometric properties of a resonator with magnetic pivoting of the balance 1 placed in a tourbillon 10 according to a conventional architecture, visible on the figure 4 , so that the balance axis D1 is parallel to the axial direction D0, to which the axis DC of the cage 11 of the tourbillon 10 is also parallel, as visible on the figure 6 .
  • the shaft 2 of the pendulum 1 cooperates with magnets 3 and 5 which are this time housed in hubs 12 and 13 of the cage 11, which hubs are pivoted at the level of pivots 14 and 15 in the structure 100.
  • the cage 11 carries the stop 7 and the exhaust mobile 8, the latter cooperates by meshing with a fixed wheel 16.
  • the vortex by its rotation, averages the vertical positions.
  • the invention therefore endeavors to develop more judicious configurations, so that the tourbillon, by its rotation, averages the HH, HB positions as well as two other vertical positions.
  • the figures 7 to 13 illustrate two advantageous variants of the invention.
  • the figures 7 to 9 relate to a first variant, comprising a balance wheel 1 on magnetic pivots, with a tourbillon 10 whose cage axis DC is substantially in the plane of watch 1000, therefore perpendicular to the axial direction D0, and where the balance axis D1 is out of the plane of the watch, in particular but not limited to parallel to the axial direction D0.
  • the figure 8 presents the typical chronometric properties of a resonator with magnetic pivoting of the balance placed in a tourbillon according to this modified architecture: cage axis DC in the plane of the watch, balance axis outside the plane of the watch.
  • the figure 9 indicates the main elements of the architecture of this mechanism.
  • the exhaust mobile 8 meshes with a fixed wheel 17 which has changed orientation relative to that of the figure 6 , since this fixed wheel 16 now extends in the thickness of the watch, and no longer flat.
  • the vortex 10 by its rotation, averages the positions HH, HB and two other vertical positions.
  • the figures 10 to 13 relate to a second variant, comprising a balance 1 on magnetic pivots, with a tourbillon 10 whose cage axis DC is substantially out of the plane of the watch, and the balance axis D1 in the plane of the watch.
  • the figure 11 presents the typical chronometric properties of an oscillator with magnetic pivoting of the balance 1 placed in a tourbillon 10 according to this modified architecture: cage axis DC outside the plane of the watch, axis of the balance D1 in the plane of the watch.
  • the pendulum axis no longer being outside the plane of the watch in a conventional manner, the chronometric positions are no longer equivalent with the three previous cases.
  • the positions HH and HB correspond to an averaging of the positions where the pendulum axis is horizontal.
  • the vortex 10 averages the positions where the balance 1 is coaxial with the earth's gravity field (equivalent HH and HB of the figure 2 ) as well as two positions where gravity is perpendicular to Earth's gravity.
  • This tourbillon very clearly improves the chronometric balance of this system. Depending on its size, its vertical size can be significant, which then reserves the use for thick watches, typically large complications. However, the improvement in chronometric properties is such that the invention makes it possible to reduce the diameters of the balance and the cage, in order to restrict the total size, and make the vertical size of such a tourbillon compatible with any Huawei horlogerie watch.
  • the figure 15 constitutes a particular example of geometry.
  • exhaust line may include one or more square or oblique references. This also makes the whole mechanism very compact.
  • the invention relates to a regulating member 30 for a watch 1000 comprising a fixed structure 100 extending substantially perpendicularly to an axial direction D0.
  • This regulating member 30 comprises a regulating member with a pendulum 1 arranged to pivot around a pendulum axis D1.
  • this pendulum 1 is pivoted by magnetic pivots, or directly in said fixed structure 100 which carries magnets 3, 5, which are arranged to give the pendulum axis D1 an oblique or perpendicular orientation relative to in the axial direction D0, or else in a cage 11, arranged to pivot about a cage axis DC, and which comprises a device for canceling the step deviation in the vertical positions 10, constituted by a vortex or a carousel, which comprises the regulating member 30, and the cage 11 carrying magnets 3, 5, defining the balance axis D1 perpendicular or oblique with respect to the axis of cage DC.
  • the pendulum 1 is pivoted by such magnetic pivots in such a cage 11, the cage axis DC of which is perpendicular or substantially perpendicular to the axial direction D0. More particularly, this axis of cage DC is perpendicular to the axial direction D0.
  • the balance 1 is pivoted by such magnetic pivots in such a cage 11, the cage axis DC of which is parallel or substantially parallel to the axial direction D0. More particularly, the cage axis DC is parallel to the axial direction D0.
  • the cage axis DC is perpendicular or oblique to the balance axis D1. More particularly still, in the first or the second variant, the cage axis DC is perpendicular to the balance axis D1.
  • the balance 1 is arranged to cooperate indirectly, through a stopper 7, with an exhaust mobile 8 which meshes with a fixed wheel 16.
  • the axis of said fixed wheel 16 is perpendicular to the axial direction D0.
  • the axis of said fixed wheel 16 is parallel to the axial direction D0.
  • the pendulum 1 is pivoted by magnetic pivots directly in the fixed structure 100 which carries magnets 3, 5 arranged to give an oblique orientation to the pendulum axis D1 relative to the axial direction D0, but not perpendicular to this direction axial D0. More in particular, the pendulum 1 is arranged to cooperate indirectly, through a retainer 7, with an exhaust mobile 8 which is arranged to be driven, directly or through a gear train, by energy storage means . More particularly, as visible on the figure 15 , the pendulum 1 is arranged to cooperate obliquely with the retainer 7.
  • the invention also relates to a watch 1000 comprising a fixed structure 100 extending substantially perpendicular to an axial direction D0, and such a regulating member 30, and comprising energy storage means arranged to drive, directly or through a gear train, the cage 11 when the regulating member 30 comprises a tourbillon or a carousel, or else the exhaust mobile 8 when the regulating member 30 does not include a tourbillon or carrousel.
  • the regulating member 30 is further modified, by replacing the pivots of the balance wheel 1 with magnetic pivots, and / or by inserting the balance wheel 1 into a cage 11 arranged to pivot around a DC axis of the cage, and which comprises a device for canceling the step deviation in the vertical positions 10, constituted by a whirlwind or a carousel, which is incorporated into the regulating member 30.
  • the regulating member 30 when the regulating member 30 is modified by inserting the balance 1 into a cage 11, the cage 11 is fitted with magnets 3, 5, constituting magnetic pivots and defining the balance axis D1 perpendicular or oblique by relative to the DC cage axis.
  • a modification of the exhaust line is also carried out by incorporating one or more square or oblique references, between the anchor and the balance plate and / or between the anchor and the escape wheel and / or between the escape wheel and the fixed second wheel.
  • the main effect of the magnetic pivots is to group the walking curves in vertical positions, with substantially linear walking curves and with a small drift, and, when this arrangement is cumulated with an oblique orientation of the axis pendulum, the walking curves in all positions are both substantially close to each other, with linear gaits, and curves corresponding to the vertical positions almost confused.
  • the rotation of the average cage at least partially positions where the earth's gravity is coaxial with the pendulum axis (magnetic).
  • the chronometric balance of the regulating organ is better in all positions of the watch.
