Definitions

  • the subject of the invention is an irregular display mechanism for a timepiece intended to be driven by a base wheel of a clockwork movement and to display a series of indications or data relating to the time or again with data relating to the operation of the timepiece, such as the power reserve.
  • the basic wheel of the watch movement means any wheel intended to control a needle or a disc or any time indicating device, in particular any wheel intended to control the display of the seconds, minutes, hours, date, the day, the week, the month, the phases of the moon or the year, etc. ..., or a piece of information relating to the operation of the timepiece, such as the power reserve.
  • the different quantities displayed by a timepiece are associated with graduations distributed regularly over a display sector, generally worn by the dial, and which can extend less than 360 degrees.
  • the patent CH 694 349 A5 in the name of the Applicant discloses a retrograde timepiece display mechanism by which two indicator hands are driven continuously, each from a cam controlling the pivoting of a rocker carrying a rake arranged in engagement with a pinion bearing the corresponding needle.
  • a spring acts on each latch to hold a finger it bears against the periphery of the corresponding cam, thereby defining the indicating position of the associated needle.
  • An object of the present invention is to provide a timepiece display mechanism, of the same type, by means of which the display can be made in an atypical manner, in particular to adapt to certain particularities of the current way of life. the man.
  • the irregular display mechanism according to the invention is characterized in that the periphery of the cam is arranged in such a way that a rotation of the cam of a given rotation angle causes a variable displacement of the cam. display member depending on the angular position of the cam with reference to the frame.
  • the cam can be mounted on a wheel driven by an intermediate gear meshing with the base wheel.
  • the elastic means may comprise a prestressed spiral spring whose one end is fixed while its second end is integral with a wheel having a kinematic connection with the pinion.
  • the base wheel is the hour wheel of the watch movement, the rake meshing with a pinion hours indication carrying a needle running a series of hours irregularly arranged on a dial of the coin depending on the configuration of the cam.
  • the display of the hours can be adapted to the occupation habits of the man.
  • the display of the hours between noon and two o'clock extends over a greater angular sector than the rest of the indications of the hours, to give the wearer of the timepiece the It seems like he has plenty of time to eat his mid-day meal.
  • the mechanism can be used to display seconds, minutes, hours, date, day, week, month, moon phases, year, more time, or relative data. the operation of the timepiece, such as the power reserve.
  • the movement for a timepiece intended to receive the display mechanism of the invention has a power reserve of several days.
  • the mechanism can then be adapted, more particularly its cam, to display the value of the power reserve on a larger angular sector for the last day than for the others, so as to attract more easily the wearer's attention to the imminent stoppage of movement.
  • the drawing represents by way of example, a mode of execution of a mechanism according to the invention.
  • Fig. 1 is a view of a timepiece having a dial allowing an irregular display of hours
  • the Fig. 2 is a view of a display mechanism for realizing the display of the time represented in the center of the dial of the Fig. 1 .
  • the base wheel of the watch movement has the reference number 1 and is the hour wheel.
  • the basic base wheel 1 transmits the movement to a return 2 which transmits its rotational movement to a wheel 3 integral with a cam 3 '.
  • the wheel 1, the return 2 and the wheel 3 are made so that the wheel 3 and therefore the cam 3 'make a turn while the wheel 1 takes a turn.
  • a rocker pivotally mounted on a frame member (not shown) of the movement carries a rake 4 'and a finger 4 disposed in abutment against the periphery of the cam 3', defining an indicating position of the rocker.
  • the cam 3 ' has an irregularly shaped periphery of snail, more precisely, whose radius of curvature does not vary in a regular manner, giving rise to an irregular movement of the rake 4', via the finger 4, this movement irregular being transmitted to pinion 1 '.
  • the latter is arranged in engagement with a reference 5 kinematically connected to resilient means of the pinion, namely a wheel 6 integral with a prestressed spiral spring 6 '.
  • the preloading of the spiral spring has the effect of holding the rocker in its indicating position, that is to say with its probe finger bearing against the periphery of the cam.
  • the display mechanism described and shown is of the retrograde type, the rocker pivoting between two extreme positions respectively associated with the weakest and largest radii of the cam.
  • the pinion 1 ' carries an hour hand, represented in the Fig. 1 drawing, browsing an irregular display of hours placed in the center of the dial.
  • the mechanism can also be used to display other data than hours, such as seconds, minutes, years, months, phases of the moon, or a magnitude relative to the operation of the timepiece such as the power reserve.
  • the mechanism can be used with any mechanical or quartz timepiece.
