Definitions

  • the present invention relates to a mechanical movement for a timepiece, in particular for a wristwatch.
  • the invention relates in particular to a movement comprising a regulating member mounted in a mobile cage.
  • Traditional mechanical watches comprise a regulating member provided with a balance and a spiral spring.
  • the regular oscillations of the hairspring which contracts and then regularly breaks down determine the running of the watch.
  • the precision of the regulating members is however affected by the gravity which tends to deform the hairspring under its own weight and to disturb the rotation of the balance if it presents an imbalance.
  • the friction between the axes and the bearings or stones are strongly influenced by their position relative to the field of gravity.
  • the cage rotates almost continuously (typically once a second, accelerations and decelerations being barely perceptible) and usually performs one revolution per minute. At least one axis of rotation of the cage is on the same line as the axis of rotation of the balance; however, multi-axis vortices are also known.
  • the cage is an integral part of the wheel, that is to say that the escape wheel is driven only when the cage is rotating. If you remove the cage, the watch stops. Finally, the rotation of the cage is produced by the unwinding of a gear on a fixed ring linked to the plate.
  • the axis of rotation of the cage is off-center with respect to the axis of the balance.
  • the cage is rotated by a separate wheel; if this gear is removed, the watch continues to operate with a stationary cage.
  • EP1686435 describes a timepiece comprising a tourbillon with a cage rotating about an axis oblique or parallel to the dial. The rotation of the vortex is continuous; the axis of the cage is directly driven by a wheel of the timepiece.
  • WO2005043257 describes a movement with two swirls. Each of the two cages rotates almost continuously, being driven by saccade each time the escapement gives an impulse to the pendulum.
  • the indexing frequency of the two vortices is therefore determined by the movement of the escapements and remains necessarily important.
  • WO2006099882 describes a movement with two regulating organs. Only one regulating organ is driven at every moment. In one embodiment, one organ is used at night and the other during the day. In one embodiment, the movement comprises two swirls operating alternately. The tourbillon used at all times, however, operates continuously, with the disadvantages mentioned below.
  • rotating a regulating member provides a number of additional benefits unrelated to accuracy.
  • rotating the balance and the hairspring makes it easy to observe it from different angles, which is useful, for example, to check its progress or to quickly check if the watch is stopped.
  • the precise running of the watch can in this case be controlled by means of a velocimeter which observes oscillations of the balance or the escapement.
  • the rotation of the regulating member makes it possible to animate the dial of the watch and to give it a less fixed appearance.
  • An object of the present invention is therefore to provide a new means of animating the regulating member of a watch movement, and incidentally to compensate statistically the effects of gravity, especially when the watch is not worn.
  • the regulating member of the invention therefore rotates at an irregular speed, in a discontinuous manner.
  • it rotates rapidly once an hour, and is therefore motionless most of the time.
  • the rotation every hour is preferably less than 360 °, for example of the order of 60 °; thus, it is possible to deduce the present time simply by observing the position of the regulating organ.
  • discontinuous rotation is meant in this application a rotation carried out intermittently with a frequency clearly perceptible even by a casual observer, that is to say a rotation that clearly distinguishes between the phases of immobilization of the frame of the regulating member and the phases, preferably much shorter, in which this frame is rotated in an indexed manner.
  • the period between two successive movements of the frame must be greater than one second, preferably greater than 10 seconds, for example one minute, 5 minutes or even one hour. The user thus has sufficient time to carefully observe the regulating organ in each of the successive positions that this regulating organ can adopt.
  • the periods of immobilization are very long compared to periods of rotation, preferably several tens, hundreds or thousands of times longer. The regulating organ is thus almost always immobile with respect to the watch case, and is not subject to undesirable forces and couples. caused by frequent rotations and accelerations of a whirlpool or a carousel.
  • the discontinuous rotation of the frame is obtained using a member other than the exhaust which accumulates energy during the long immobilization phases and then releases it at each rotation.
  • the regulating member is preferably mounted in a frame which rotates at an oblique angle or perpendicular to the axis of rotation of the beam.
  • the frame rotates not only the entire sprung balance, but also the entire escapement, the seconds wheel and even the wheel averages.
  • the system in rotation with the frame is therefore much more important than in a conventional tourbillon, so that the animation is much more visible. This arrangement also allows to observe from different angles a number of larger parts.
  • the frame carrying the regulating member is not rotated each time the escapement gives an impulse to the balance; instead, the rotation of this frame is provided by a separate drive mechanism, employing a separate drive train from a gear wheel or pinion gear, for example the second wheel of great average.
  • the rotation frequency is thus distinct and independent of the oscillation frequency of the regulating member.
  • the regulating member used at every moment to adjust the running of the watch is mounted in a frame rotating discontinuously.
  • the horizontal plane is perpendicular to the page and to the verticals of the figure.
  • the plane of the minute hand, the bottom plane of the watch or the barrel plane are all horizontal.
  • the plane of movement is also horizontal and corresponds to the plane of the plate on which is mounted for example the wheel of medium or barrel.
  • frame designates in this application an assembly constructed around a plate or a movable bridge which carries the escapement, the regulating member and possibly other elements of the red for example.
  • the movement schematically illustrated on the figure 1 comprises an oscillating mass 1 and / or a winding stem 2 for retensioning a mainspring spring 3 storing the energy necessary for the movement of the watch.
  • the barrel meshes with a small average gear 5 mounted on the same axis as a first medium wheel 6 and a second medium wheel 8.
  • the first wheel of large average 6 is bell-shaped which allows it to mesh a pinion of small average 10 mounted on a horizontal axis 12, perpendicular to the axis of the wheel 6.
  • the second wheel of large mean 8 is on the other hand right to mesh a pinion in the same plane.
  • a bevel gear system can replace bell and pinion transmissions.
  • a differential is preferably arranged for example between the medium wheel 6 and the horizontal input axis 12 of the energy on the mobile frame, in order to avoid disturbing the gait of the regulating member when the turntable changes. position.
  • the horizontal axis 12 passes through a bearing 14 through a frame 16.
  • the frame 16 preferably makes it possible to see the regulating member in different positions when the watch is worn.
  • a conical return 18 at the other end of the shaft 10 makes it possible to modify again the axis of the gears, by meshing a conical return 20 mounted on an axis 22 connected to the mobile frame 16.
  • the axis 22 of the second conical return turns therefore in a vertical plane perpendicular to the page.
  • a small average wheel 22 is also mounted on the axis 22 and actuates the small second gear on a parallel axis.
  • the speed of rotation of the second wheel on the same axis is braked by the exhaust pinion 30 with which it meshes.
  • This pinion is connected to the escape wheel 32 cooperating with the anchor 34, the balance 36 and the balance 38 of a conventional regulating member.
  • the frame thus carries more organs 18-38 than the cage of vortices or conventional carousels; it is actually a turntable bearing not only the regulating organ, but also a part of the cog.
  • the movable frame is rotated for a separate drive train from the second medium wheel 8.
  • a pinion 82 driven by this wheel 8 actuates the road wheel 80 carrying the wheel 72 and the minute hand 74. setting time is done by the drawn crown acting on the floor wheel 80.
  • the minute hand takes a turn in 60 minutes to display the minutes in a conventional manner on the dial.
  • An auxiliary cylinder (buffer drum) 78 is recharged by the road wheel 80.
  • the energy of this second cylinder is released suddenly every hour by the mechanism 60 comprising a trigger cam controlled by the gear train, for example by the gear wheel. small average.
  • the auxiliary barrel is recharged by the main barrel; the tension of the two barrels is equalized.
  • An exhaust or centrifugal speed regulator 56 makes it possible to control the speed of rotation of the axis at the outlet of the regulator, so as to cause a crank-rod system setting the driving pulley 52 into motion at a constant constant speed.
  • the connecting rod and crank system makes it possible to transform this movement at a constant speed into an indexing of the driving pulley 52.
  • the driving pulley accelerates and decelerates progressively, preferably according to a sinusoidal law, which makes it possible to eliminate the shocks at start-up. and at a standstill.
  • the driving pulley rotates in seconds of 60 ° every hour. It allows to drive the track 46, so as to make visible the next pallet.
  • the twelve successive pallets of the track carry the numbers from 1 to 12 so as to display the hours.
  • the caterpillar in turn drives the driven pulley 44 mounted on a shaft 42.
  • the end of the shaft is housed in a socket 40 in the mobile frame 16.
  • the rotations of the crawler every hour are thus transmitted to the frame 16.
  • the frame also jumps 60 ° every hour by rotating about a horizontal axis.
  • the invention also relates to movements in which the wheel and the second gear, and possibly the wheel and the average gear, are mounted with the regulating member in a rotating frame, regardless of the rotational speed of this frame.
  • the frame may also be mounted so as to place the balance in a plane oblique to the plane of movement, for example with an angle of the order of 47-50 °. This arrangement makes it possible in particular to reduce the horizontal surface occupied by the balance, while avoiding a vertical arrangement requiring too much thickness.
  • the frame 16 is rotated by the rotating shaft 42. It is also possible in the context of the invention to rotate the frame in the manner of a cage in a conventional vortex, c that is to say by unrolling one of the wheels mounted in the frame around a wheel or a toothed member fixed relative to the platen of the movement.
  • the frame carries the greater part of the finishing gears, the balance, the balance, the hairspring and the exhaust. These elements therefore occupy a set of successive orientations in space with respect to the field of gravity when the watch is not worn. Consequently, the differences in the positions in the different positions are compensated for by statistical effect, and this without resorting to a vortex or a carousel.
  • the watch movement is advantageously mounted in a watch case comprising a glass which covers both the upper face of the movement, in order to see the dial, as well as one of the lateral faces, or a lateral segment, of the movement, in order to disclose a portion of the mechanism with the display 44-46-52 and / or the regulating member 16.
  • the invention therefore also relates to such a glass covering the upper face and a single side face, or a single segment less than 120 ° , a movement, the other faces or segments being opaque or closed by the middle part.
  • the invention also relates to a watch case provided with such a glass, as well as a watch complete with such a glass and a movement comprising all or some of the characteristics described above.
