  • this cam 5 is to impose a certain duration of travel of the probe 6, to achieve a change of display, clearly visible by the user: the jump is spread over a period of a few seconds, corresponding at the longest possible distance on the periphery of the cam.
  • the mechanism 1 comprises a regulating mechanism 9 for regulating the rotational speed of the mobile carrying the cam 5: this mechanism 9 in the illustrated version includes a control gear, which meshes with that of the second mobile 30, or respectively the first mobile 4 which drives or carries the cam 5) to limit its speed of rotation when the finger 7 is released.

  • This return to the position of the lower level 511 by the steep edge of the threshold 52 is instantaneous, and without influencing the display, for example through a system finger ratchet on a star, or the like.
  • each jump corresponds to a change of state of the display 100 between an earlier state and a posterior state
  • the jump duration corresponds to the lapse of time elapsed between the stable display of the previous state and the display. stable of the posterior state.

  • the trigger anchor 8 thus performs a come and go in 24 hours. It is understood that the illustrated example relates to a single daily jump at midnight for the particular case of a date, but it is possible to extrapolate the invention to any display with another period by adjusting the gear ratios, the number of fingers 7 and their positions, the number of third mobiles 80, including anchors 8, the number of resetting thresholds 52, to perform other jumping commands.
  • an application with two daily jumps at noon and midnight allows the change of state of an AM / PM indicator
  • an application with two daily jumps at 6 o'clock and at 18 o'clock allows the change of state of a day / night indicator.
  • Another application still concerns a weeklong, with rotation of seven days, and display of the day of the week. Many other applications are accessible and advantageous to those skilled in the art, because the invention provides a new visibility of display changes, which is a pleasant improvement for the user.
  • the back and forth of the anchor 8 thus releases the rotation of the drum 3, in particular the drum 3 of the barrel 10 in the case of the figures, by its finger 7, at midnight to allow its rotation by an angle of approximately 330 ° and at noon of 30 ° complementary.
  • the eccentric pin 42 is assembled on the shaft 41 by friction, to allow indexing of the jump, for example at midnight for the date.
  • the rotation of the drum 3 of 330 ° causes the display mechanism, particularly of date, by the cam 5, in particular a spiral 51, which is attached thereto, and which applies a movement to the feeler 6, which is in the figures a pebble of the date training, arranged to move the display 100.

  • the control exhaust wheel 94 has teeth 95, which are arranged to cooperate with a control anchor 97, which comprises pallets 98 and 99. Under the torque printed by the drum 3, the control anchor 97 passes alternately of one of its pallets on the other, by driving a mass of inertia 970 which is solidary to him.
  • This oscillating movement of the control anchor 97 has a natural frequency which, without being as isochronous as a balance spring, allows a good regulation of a function.
  • the frequency of the oscillator can be substantially modified with a complementary spring 971, here mounted movably on a screw head 972, which makes it possible to change the function time to a small extent.
