Definitions

  • the subject of the present invention is a timepiece comprising a central mobile making one revolution in n hours, n being an integer greater than 1, and carrying n rotary mobile satellites arranged at regular intervals on a circle centered on the axis of the central mobile bearing the hour digits, distributed on the satellites at the rate of 12 / n or 24 / n digits per satellite, a scale graduated in minutes extending over a circular arc of 360 ° / n centered on the axis of the central mobile, and at least one fixed finger driving said satellites in turn by a fraction of a turn at each turn of the central mobile, the assembly being arranged so that the hour digits move successively in front of the scale of minutes.
  • Such a timepiece is known from Swiss patent 49,456.
  • This document describes a clock in which the central mobile consists of means provided with radial arms at the ends of which are mounted satellites also provided with arms each carrying a number d 'hour and driven in rotation, by a determined angle, at each revolution of the central mobile, by a fixed finger against which come in turn to abut the arms of the satellites.
  • the satellites must be mounted with greasy friction on their axes.
  • each satellite In the most suitable case of three satellites with four branches, each satellite must be driven a quarter turn each time the central mobile, this training a quarter turn requiring a time of the order of a quarter d hour during which the central mobile is braked by the friction of the satellite on its axis. Therefore, for guarantee the precision of a timepiece equipped with such time display means, it is necessary to have a relatively very high torque on the axis of the central mobile and also an energy source high to exert this torque for about a quarter of the time spent on the timepiece. Such a display device cannot therefore be used in a wristwatch where there is only little energy available.
  • the present invention aims to allow the use of the display mode described above in a wristwatch whose energy source is mechanical or electrical.
  • the timepiece according to the invention is characterized by the fact that the central mobile consists of a wheel, that the satellites consist of discs secured to stars and that the central mobile carries jumpsuits cooperating respectively with each of the stars to position them angularly.
  • the positioning of the satellites by stars and necklaces makes it possible to control the disturbing torque resulting from the rotation of the satellites much more precisely.
  • the strength of the necklaces can indeed be determined precisely, which is not the case with fatty friction.
  • the positioning by stars and necklaces also improves the accuracy of the minute indication.
  • the display mode suggested by the prior art therefore becomes usable in a wristwatch.
  • the partially represented watch essentially comprises a centered wheel 1 performing one revolution in three hours and carrying three transparent disks 2, 3 and 4 rotatably mounted on the rim of the wheel 1, that is to say on a circle concentric with the axis of wheel 1 and on which they are regularly distributed at 120 ° intervals.
  • Each of these discs is integral with an eight-tooth star 5, respectively 6 and 7, each of these stars cooperating with a jumper 8, 9 and 10 also mounted on the rim of the wheel 1 and maintaining the stars in a determined position .
  • Discs 2, 3 and 4 carry the hour digits distributed over the discs at the rate of four digits per disc.
  • Disc 2 has the numbers 3, 6, 9 and 12
  • Disc 3 has the numbers 2, 5, 8 and 11
  • Disc 4 has the numbers 1, 4, 7 and 10, these numbers being distributed angularly on each disc at 90 ° intervals.
  • the discs 2, 3 and 4 are further provided with triangular index 13 above each digit.
  • the wheel 1 with its discs is arranged above a dial 11 having a sector 12 concentric with the wheel 1 and extending over a little more than 120 °. This sector 12 carries sixty graduations over 120 °. During the rotation of the wheel 1, the hour digits and the corresponding index move successively opposite the graduations of the sector 12.
  • the dial 11 also carries two vertical pins 14 and 15 placed on the trajectory of the stars 5, 6 and 7, so that at each revolution of the wheel 1, each of the eight-tooth stars is driven twice by an eighth of a revolution by these pins. Each revolution of the wheel 1, each disc has therefore made a quarter turn, which has the effect of bringing a new hour digit into a position such that this digit is opposite the scale of the minutes when it arrives at sector 12.
  • the watch is provided with a glass 16 (FIG. 2) which is largely opaque, so as to allow only sector sector 12 to be seen.
  • the wheel 1 is mounted in place of the hour hand on the hub 17 of a cannon wheel 18, itself mounted on an existing roadway 19 making one revolution in one hour .
  • This roadway 19 is mounted on a first roadway 20, in a known manner, itself mounted on the center tube 21.
  • the pinion 22 of the roadway 19 drives a special timer consisting of a timer wheel 23 and a pinion timer 24 driving the barrel wheel 18.
  • the number of teeth of these mobiles is such that the carriageway 18 makes one revolution in three hours.
  • Each of the discs 2, 3 and 4 with its star, is rotatably mounted on an axis 25 on which it is retained by a screw 26.
  • the embodiment described is of course susceptible of numerous variants.
  • the discs could be replaced by crosses.
  • the graduation of the minutes could be on the ice or on the telescope.
  • the speed of rotation of the wheel 1, the number of discs, the number of digits per disc and the size of the minute sector could be different. These quantities are however interdependent.
  • n hours an integer greater than 1
  • the wheel 1 will carry n satellite disks and the hour digits will be distributed over these satellite discs at the rate of 12 / n digits per disc, and the scale of the minutes will extend over an arc of a circle of 360 ° / n.
  • the hours are displayed from 1 to 24, the hour digits must be distributed 24 / n digits per satellite disc.
  • the number of star teeth and / or fixed pins will be chosen according to the required angle of rotation of each disc at each turn of the wheel 1.
