Definitions

  • the invention relates to a device for driving a display element.
  • the invention also relates to a calendar system or module comprising such a device.
  • the invention also relates to a timepiece movement comprising such a device or such a system or such a module.
  • the invention finally relates to a timepiece comprising such a device or such a system or such a module or such a movement.
  • the invention relates to a drive device making it possible to carry out the instantaneous passage from the display of a value to another of a quantity linked to time or derived from time, for example the date or the hours.
  • Devices comprising a drive member constituted by a finger integral with a cam, said cam cooperating with an energy accumulator, so that this member can instantly cause, at least with an angular pitch, a toothing a display member, which is angularly indexed by a jumper.
  • the energy accumulator usually consists of an elastic return means cooperating with a rocker, which bears against the side of the cam under the effect of said elastic return means, and allows, at the instant of passage instantaneous display of a value to another of a quantity linked to time or derived from time, to overcome the torque produced by said jumper under the effect of the torque restored by said elastic means.
  • the instant of the instantaneous passage of the display of a value to another of a quantity linked to time or derived from time depends on multiple parameters such as, for example, the coefficients of friction between the elements taking part in the device for training, especially at the level means for pivoting the drive cam and elements constituting the accumulator.
  • the instant of the instantaneous passage can vary in particular as a function of the speed of the drive cam relative to the frame of the timepiece.
  • the instant of the instantaneous passage of the date can therefore vary according to the speeds of the various cogs of the movement on which the calendar mechanism is mounted.
  • the speed of the drive cam is unequivocally defined by the speed of the gear train of the movement which drives said cam.
  • the speed of the drive cam can vary according to the speed of a time-setting train which can also drive said cam.
  • the instant of the instantaneous date change may vary slightly depending on the mode of operation of the movement. It follows that a jump in date can take place when the timepiece, in particular the hour and minute hands, does not indicate exactly midnight. Similarly, in the case of a timepiece with jumping hours, an hour display jump may take place while the timepiece, in particular the minute hand, does not indicate exactly one whole hour .
  • the vertex is more like a surface, in particular a rounded surface, than a point or an edge due to the methods of manufacturing the cam, and in particular its termination methods.
  • the object of the invention is to provide a device for driving a display element making it possible to improve the devices known in the art. prior.
  • the invention provides a device for driving a display element, the operation of which is optimized in terms of reliability and precision.

  • the watch movement can be a mechanical movement, in particular an automatic movement.
  • the watch movement can alternatively be electronic.
  • the movement may include a watch calendar system 200 or a watch calendar module 200.
  • the movement 300 or the watch calendar system 200 or a watch calendar module 200 comprises a device 100 for driving a display element 10 of a magnitude linked to time or derived from time.

  • the display element can be or include a disc bearing numerical and / or alphabetical and / or alphanumeric indications, in particular a disc cooperating with a window.
  • the display element can be an indicator, such as a needle, in particular an indicator cooperating with a blade.

  • an energy accumulator 5 like a spring
  • a driving mobile 1 provided with a drive member or finger 2 which is integral with the cam 3 cooperating with the accumulator energy 5, via the rocker 4, so that the drive finger 2 can instantly drive (either in a fraction of a second) with an angular step the display element 10, in particular a toothing 10a of the display element 10, which is indexed in position by a spout 20a of a jumper 20.
  • the driving mobile 1 also comprises a wheel 6 which is connected to a finishing train 7 of the basic movement and which, during the conventional operation of the movement, performs one complete rotation in 24 hours.
  • This wheel 6 is also connected to a gear train of correction or time setting 8 which is capable of driving said wheel 6 at a non-predefined speed and dependent on the wearer's adjustment habits, during a correction or time setting operation.

  • the action of the rocker 4 on the cam 3 makes it possible to rotate the cam 3 and the finger 2 which in turn drives the display element 10.
  • This action of the rocker 4, which is caused by the spring 5, enables the display element 10 to overcome the torque produced by the jumper 20.
  • the wheel 6 leads the cam 3 and accumulates the energy necessary for a sudden displacement of the finger 2 so that it exerts a short action on the display element 10 to cause an instantaneous jump of the display element 10.
  • This necessary energy is accumulated by arming the spring 5 via a first portion 3a of the profile of the cam 3 and rocker 4.
  • the rocker 4 is in contact with the top 3b of the profile of the cam 6, namely the zone 3b of one end of a portion 3a, which includes the point 30b which is the point of the cam furthest from the axis A3 of rotation of the cam 3.
  • This area 3b may, for example, be in the form of a curve or a rounded 3b which includes the point 30b furthest from the axis A3 of rotation of the cam 3.
  • this zone 3b can be reduced to the point 30b furthest from the axis A3 of rotation of the cam 3.
  • this degree of freedom can be offered by a “freewheel” type solution placed between the finger 2 and the cam 3 on the one hand and the wheel 6 on the other hand.
  • the finger 2 is preferably positioned and held within the toothing 10a by means of the rocker 4, the roller 4a of which is applied against a third portion 3d of the profile of the cam 3, which is in hollow shape (as shown in the figures 3 and 4 ).
  • the finger 2 thus positioned allows the display element 10 to be braked, and avoids any risk of double display jump.
  • the zone 3b constitutes a transition zone between the portions 3a and 3c of the cam 3 (as shown in the figures 2 and 3 ).
  • zone 3b constitutes a transition zone where the torque applied by the rocker on the cam 3 changes sign and goes through zero.
  • the ratio C3 / C4 is proportional to the ratio of the lengths A3P / A4P, with P the point of intersection of the reaction force F between the roller 4a and the area 3b of the cam 3 with the line of centers A3A4 connecting the axis of rotation A3 of the cam 3 to the axis of rotation A4 of the rocker 4, the reaction force F possibly being turned by the angle of friction with respect to normal at contact N.
  • the torque C3 at the cam 3 when the latter is carried out, corresponds to a displacement of the point of intersection P on the line of centers A3A4.
  • An angle a is defined, in a plane perpendicular to the first and second axes A3, A4, between a first straight line passing through the point of contact between the vertex 3b of the cam 3, in particular the point 30b furthest from the axis A3 of the cam 3, and the rocker 4, and the first axis A3, and a second straight line passing through the first axis A3 and the second axis A4.
