Definitions

  • the invention relates to a display combining clock display device comprising at least a first display arranged to cooperate via first transmission means with first drive or control means, and at least one second display, arranged to cooperate via second transmission means with second drive or control means.

  • the invention relates to the field of scientific instruments, and more particularly the field of mechanical and / or electronic watchmaking.
  • a display On a quartz movement watch, when the rotor of the stepping motor realizes a step, a display, usually a needle, performs a pivoting of a given angular step, by a few degrees. At the end of this pivoting, the needle stops, and this stop is usually accompanied by an oscillation which can be visually unpleasant for the user, and especially when the pivoting movement of the needle is slow, as when displaying a particular function, for example a compass function, with a single-phase motor. It is known to reduce or eliminate this oscillation by the interposition of an elastic friction washer in the train, so as to create a continuous friction that completely damps the oscillation, but at the cost of excessive energy consumption, and therefore a loss of yield.
  • Another way to eliminate the oscillation defect is to make a rapid movement of the needle, which then no longer has time to oscillate at the end of each step, however such rapid movement can not be achieved for a single-phase motor, as conventionally used to drive the display during the implementation of a particular function, other than the display of the time.

  • the example described in detail here of the cooperation of two displays is not limiting.
  • the oscillation of a display in particular of a hand of a timepiece or a watch, controlled by an electric motor, is caused, on the one hand by the inertia in the rotor of this motor, which oscillates after a driving impulse, and, on the other hand, by the play in the wheels, the inertia of the display or needle and the wheels making them oscillate within the limits of the play of the wheels.
  • a coupling according to the invention in particular magnetic or electrostatic, makes it possible to introduce momentarily, and in certain positions only, an additional force or torque, which is similar to a friction due to the effect produced, which makes it possible to damp the oscillation.
  • the damping quality depends on the setting of the coupling, but this is always present. In short, it is only in particular relative positions of displays or needles that this depreciation is created.

  • first coupling means 12 and the second complementary coupling means 22 are arranged respectively on the first transmission means 11 and on the second transmission means 21.
  • the first transmission means 11 or the second transmission means 21 are disengageable under the effect of a command initiated by a control means 30, so as to allow the drive of the first display 1 and second display 2, which is disengaged from its drive means or control, by the one which is engaged with its drive means or control.

  • This training can, again, be obtained under the effect of the processing of a signal emitted by a measurement sensor or of a status report of a physical quantity, for example a radioactivity sensor, a barometric sensor, a sensor of a lighting, or other.
  • the output maneuver of the coupling position is performed with a printed pulse, directly or indirectly, at least one of the two displays relative to the other.
  • this pulse can easily result from a peak current or voltage on a drive motor, or the like.
  • the pulse can be achieved by a cam or a ramp.
  • this output maneuver not only intervenes at the output of the coupling position, but also at any moment when, due to the normal operation of the movement, the first display 1 and the second display 2 are in the particular indexing position relative to each other.
  • the first coupling means 12 and the second means of complementary coupling 22 come into cooperation each time these two needles are in alignment position, that is to say each time the compass function is implemented, friends also every time the normal movement of the movement presents them in alignment with each other, which happens twenty-four times a day for a twelve-hour display dial.

  • the first drive or control means 10, and the second drive or control means 20 can also operate in continuous movement, they then require a dimensioning allowing them to overcome, in normal operation, the force or the torque of attraction, while the use of a disengagement function of one of the two displays at the end of the docking maneuver allows the force or the attraction torque to gain ascendancy over the inertial force, in order to perform a damped indexing, and without any vibration.
  • the indexing between the displays can be multiple, the figure 2 illustrates a case where a wheel of the first transmission means 11 carries, opposed to 180 ° relative to its axis of pivoting, first coupling means 12A, and other first coupling means 12B, while a wheel of the second transmission means 21 carries a single second coupling means 22.

  • the first display 1 is constituted by the hour hand
  • the second display 2 is constituted by the minute hand.
  • These two needles change function when switching to compass mode, when they are aligned with each other and then facing north magnetic.
  • the object of the invention is to rapidly dampen the oscillation of the needle at each end of step, in compass mode. Since the duration of operation in compass mode represents only a very small part of the operating time of the watch, the solution offered by the invention must not penalize consumption in normal operation.
  • the alignment configuration of both hands occurs 24 times a day in normal operation for normal time display.
  • Engine control both needles are done one after the other.
  • the minute hand moves the minute hand remains fixed, then when the hour hand has finished its step, it is the minute hand that moves while the hour hand remains fixed.
  • the damping of the end of the pitch of the needle is achieved by the coupling, preferably magnetic, or electrostatic, between the hour wheel and the minute wheel.
  • the magnetic coupling can be achieved by magnet on the minute wheel and a magnetic pin on the hour wheel, or directly at the level of the needles.
  • the magnetic coupling with the hour wheel immediately dampens its oscillation.
  • a mechanical coupling can be achieved in the same way with spring elements on the wheels or mechanical, the latter solution is however less advantageous than the magnetic and electrostatic solutions in terms of energy consumption.
  • the solution thus implemented by the invention is made at the mechanical components of the timepiece, and does not impact the driver. The very low over-consumption generated by this solution only takes place in compass mode and 24 times / day on a few rotor impulses.
  • the coupling torque is dimensioned, resulting from the cooperation of the first coupling means 12 and the second coupling means 22, so that it remains lower to the positioning torque delivered by the drive motor of one of the displays, reported at the pivot axis of this display.
  • one (static) display is immobilized before the other (mobile), as in particular in the example of the compass above where one always cuts one of the two engines while one activates the other, the static display is thus not driven by the movement of the mobile display.
  • control means 30 comprises software that blocks the motor of the static display by re-injecting current into the coil.
  • the mobile display may require more current to be able to take its step, but the impact on consumption remains low, because in the preferred case of the needles of a clock, the alignment of the needles is done 24 times per day only.
  • the invention also relates to a timepiece 1000 comprising a control means 30 arranged to control a first display 1 by first drive or control means 10, and to control a second display 2 by second drive means or control 20, and including such a display device 100, controlled by this control means 30.
