Definitions

  • the present invention relates to a universal walking equation. More specifically, the present invention relates to such a walking equation that indicates precisely the time when the sun is at the zenith regardless of the position, in longitude, the wearer of the watch.
  • the sun In the same time zone, the sun is not at the zenith at the same time depending on whether one is at the extreme east, the center or the extreme west of this time zone. Between the two extreme positions, the time difference is 59 minutes.
  • the equation cam of time 1 is rotated at the rate of one revolution per year from the simple or perpetual calendar mechanism that includes the timepiece.
  • the cam 1 carries a disk of months 2 which rotates at the same speed as it and which makes it possible to make the position of said cam 1 coincide with the date indicated by the date mechanism so that the minute hand of the solar time 4 indicates the exact solar time.
  • the date mechanism simple or perpetual, can be of any known type and will not be described here in its entirety. For a good understanding, it suffices to know that this date mechanism drives the equation cam of time 1 at the rate of one complete revolution per year. However, it is shown, for illustrative purposes only, a date mobile 6 driving a needle 8 which indicates the date (1 to 31). This mobile date of 6 rotates at a rate of one complete turn per month. It is actuated by the date mechanism via an intermediate date wheel 10 for reversing the direction of rotation, and a reduction wheel 12 which reduces the speed of rotation of a complete revolution per month to a lap complete per year.
  • the minute hand of the solar time 4 is driven by a differential gear 14 which has respective inputs a gear train 16 driving a minute hand of the civil time 18 and a rake 20 which cooperates with the equation cam time 1 (the rake 20 is represented on the figure 1 in its two extreme positions, once in solid lines and the other time in dashed lines).
  • the differential gear 14 comprises at least one, and preferably two satellites 22 driven by the timer of the watch movement of the watch. These two satellites 22 are able to turn on themselves and to roll on the internal toothing 24 of an equation wheel of time 26.
  • the latter also has on its outer periphery a toothed sector 28 by which it cooperates with a sector toothed 30 that has the rake 20 at one of its ends.
  • This rake is subjected to the return action of a spring (not shown) fixed on the frame of the watch and which tends to apply a feeler 32 forming the other end of said rake 20 against the periphery of the equation cam 1.
  • the solar weather display gear comprises a pinion 34 placed in the center of the differential gear 14 and carried by an axis 36.
  • This sun time display pinion 34 meshes with the planet gears 22.
  • it carries a display wheel 38 which meshes with a roadway 40 on the barrel from which the minute hand of solar time 4 is driven.
  • This wheel 38, 40 makes it possible to reduce the display of the time. solar in the center 42 of the clockwork movement of the watch, so that the minute hand of the solar time 4 is concentric with the minute hand of the civil time 18.
  • the equation cam of time 1, the time equation rake 20 and thus the equation of time equation 26 are immobile.
  • the planet gears 22 are driven by the watch movement of the watch. They therefore rotate on themselves and roll on the internal toothing 24 of the equation wheel of time 26, driving the pinion 34 to display the solar time in rotation, which allows the minute hand of the solar time 4 to rotate concomitantly with the minute hand of civil time 18.
  • the gap between the solar time hand 4 and the civil time needle 18 remains constant over a period of 24 hours.
  • the equation cam of walking time 1 rotates, driven by the date mechanism that shifts the calendar from one day to the next.
  • the feeler 32 which is in contact with the periphery of the cam 1 in turn rotates the rake 20.
  • Said rake 20 by pivoting, drives the equation wheel of the time 26 in rotation.
  • the planet gears 22 being substantially immobile (they make a complete revolution in 1 hour), turn on themselves while being rotated by the equation wheel of the time 26, and cause them to rotate. turn the display pinion of the solar time 34 so as to adjust again exactly the position of the minute hand of the solar time 4.
  • the walking time equation mechanism described above thus allows, by means of a minute hand of the civil time and a minute hand of the solar time, to display at any time the time difference between the mean solar time and the true time.
  • This equation of walking time equation does not allow to indicate the civil time at which the sun is at the zenith according to the position, in longitude, of the user in the time zone.
  • EP1637941 A1 discloses a walking time equation mechanism according to the preamble of claim 1 attached to this patent application.
  • the present invention aims to overcome this problem by providing a walking time equation mechanism capable of indicating at any time and regardless of the position in longitude of the user in the time zone the difference in hours and hours. minutes between the civil time and the true time.
  • the present invention relates to a universal walking time equation mechanism according to claim 1.

At the output, the differential device 44 causes one minute of walking equation 52. As already mentioned above, the minute of walking equation 52 indicates the difference, for a given day, between the civil time and the solar time. This difference between the civil time and the solar time reaches +14 min 22 s on February 11, and -16 min 23 s on November 4.
