Definitions

  • the invention relates to a control device for a timepiece.
  • the invention also relates to a watch movement comprising such a control device.
  • the invention finally relates to a timepiece comprising such a control device or such a timepiece movement.
  • the object of the invention is to provide a control device remedying the above drawbacks and improving the control devices known from the prior art.
  • the invention proposes a control device that is compact, simple and practical to use.
  • control device is defined by claim 1.
  • Embodiments of the control device are defined by claims 2 to 9.
  • a watch movement is defined by claim 10.
  • a timepiece is defined by claim 11.
  • FIG. 1 is a schematic view of an embodiment of a timepiece according to the invention, on which circular local sections are represented to visualize satellites and planetary teeth meshing with these satellites.
  • the timepiece 200 is for example a watch, in particular a wristwatch.
  • the timepiece 200 comprises a timepiece movement 100, intended to be mounted in a case or a timepiece box in order to protect it from the external environment.
  • the watch movement 100 can be a mechanical movement, in particular an automatic movement, or even a hybrid movement.
  • This action is advantageously exerted by the user via a crown or a knob or a key mechanically linked to the control device, in particular linked to an input 2 of the control device.
  • the first mechanism 5 is a time-setting mechanism.
  • This first mechanism comprises for example a kinematic chain, in particular a cog chain making it possible to modify the display of the time.
  • This first mechanism comprises, for example, a timer train and/or a wheel 5 of a minutes wheel set.
  • the second mechanism 6 is a winding mechanism.
  • This first mechanism therefore comprises a barrel 6 and, possibly, a kinematic chain, in particular a cog chain making it possible to act on the barrel 6, in particular on a ratchet 61 of the barrel.
  • the mechanism 6 may include a pawl 62 preventing the ratchet 61 from rotating counterclockwise.
  • the first unidirectional link member 3 is arranged and/or configured to drive the first mechanism 5 exclusively when the input is operated in the first direction and the second unidirectional connecting member 4 is arranged and/or configured to drive the second mechanism 6 exclusively when the input is operated in the second direction.
  • the first mechanism 5 when the input is rotated clockwise around the axis A2, the movement of the input is transmitted to the second mechanism 6 exclusively and, when the input is rotated counterclockwise around the axis A2, the movement of the input is transmitted to the first mechanism 5 exclusively, as will be explained in detail below.
  • the first unidirectional link member 3 comprises first teeth 321, 331 cooperating irreversibly and/or the second unidirectional link member 4 comprises second teeth 421, 431 cooperating irreversibly.
  • the input is a mobile pivoted around the axis A2 on a frame 99 of the watch movement.
  • Input 2 can be a shaft, rod, pinion or wheel.
  • the input has a set of teeth 21 making it possible to transmit the movement which it receives from the user via the crown or the wheel or the key.
  • the sun gear 33 is for example made up of a pinion carrying the toothing 331 fixed, in particular riveted, to a wheel carrying the toothing 332.
  • the first toothings 321, 331 cooperate irreversibly insofar as the first toothings 321, 331 mesh irreversibly.
  • the sun gear 43 is for example made up of a pinion carrying the toothing 431 fixed, in particular riveted, to a wheel carrying the toothing 432.
  • the second toothings 421, 431 cooperate irreversibly insofar as the second toothings 421, 431 mesh irreversibly.
  • the first and second toothings are arranged and/or configured to lock when the sun gear 33 is rotated clockwise relative to the axis A3 and to lock when the sun gear 43 is rotated counterclockwise relative to the axis A4 only.
  • the teeth do not lock when the satellites are driven in the other directions.
  • the teeth may also block when it is the planet carriers 31, 41 which are driving in one direction or in both directions or the teeth may not be blocked when the planet carriers 33, 43 are driving.
  • this is not obligatory, not obligatory, preferable or not depending on the nature of the mechanisms 5, 6 driven.
  • the driven mechanism 6 is a barrel, it may not matter whether the teeth lock or not.
  • the driven mechanism 5 is a timer or a minute wheel set, it is preferable that the teeth do not jam step, in order to limit the number of driven elements and to limit energy losses when you do not act on input 2.
  • one of the first or second toothings can comprise teeth with asymmetrical profiles and/or the other of the first or second toothings can comprise teeth with asymmetrical profiles.
  • asymmetrical profile it is meant that each tooth has a first flank and a second flank, the first and second flanks being non-symmetrical relative to a radius of the wheel passing through the top of the tooth.
  • the solution represented it is possible to set the time by turning the crown in one direction and to wind the timepiece by turning the crown in the opposite direction. This is convenient. Furthermore, the solution requires a small footprint in the direction perpendicular to the plane of the figure 1 .
  • the first sun gear 33 is fixed, in particular fixed in rotation, to the input 2 and the first planet gear carrier 31 is intended to be fixed, in particular fixed in rotation, to the first mechanism 5 and the second sun gear 43 is fixed, in particular fixed in rotation, to the input 2 and the second planet carrier is intended to be fixed, in particular fixed in rotation, to the second mechanism 6.
  • the first sun gear 33 may constitute the input 2, so that the shaft 2 can be removed and the sun gears 33 and 43 can mesh with each other.
  • the second sun gear 43 can constitute the input 2, so that the shaft 2 can be eliminated and the sun gears 33 and 43 can mesh with each other.
  • the inlet when the inlet is turned in a first direction, the two wheels of the first unidirectional connecting member are driven in rotation, as is the first mechanism.
  • the two wheels of the second unidirectional connecting member are driven in rotation and it drives neither the other wheel nor the second mechanism.
  • the inlet when the inlet is turned in a second direction, the two wheels of the second unidirectional link member are driven in rotation, as is the second mechanism.
  • only one of the wheels of the first unidirectional connecting member is driven in rotation and it drives neither the other wheel nor the first mechanism.
  • the first unidirectional link member is centered on a first axis A3 and the second unidirectional link member is centered on a second axis A4, the first and second axes being advantageously parallel and separate.
  • the first and second axes can advantageously be combined. Such a configuration makes it possible to minimize the size of the device in the plane of the figure 1 .
  • the planet carriers can form a single and same part or be a one-piece assembly or the first and second sun gears can form a single and same part or be a one-piece assembly.
  • one and the same wheel can be common to the two unidirectional connecting members and carry on the two faces of its board two Breguet toothing cooperating with the Breguet toothing of two other wheels.
  • each satellite carrier can carry two or more satellites, such as three satellites or four satellites.
