Definitions

  • the subject of the present invention is a mechanism for the equation of walking time for a timepiece. More specifically, the invention relates to a mechanism for the equation of walking time driving a minute hand of true time concentric with the movement.
  • certain timepieces include, in addition to the hand which indicates the minute of civil time, a mechanism known as the equation of time which includes a hand which moves next to a graduated scale to indicate the difference between the minute of civil time and the minute of solar time for a given day.
  • This true time minute hand is actuated by a time equation cam whose profile is determined by the difference between the mean solar time and the true solar time for all days of the year.
  • the switch of a timepiece equipped with a mechanism for equation of the working time has two concentric minute hands, one indicating the minute of civil time, and the other indicating the minute of true time.
  • the difference between the minute hand of civil time and the minute hand of true time is determined by the difference between the mean solar time and the true solar time for the day of the year considered.
  • the real time minute hand of a walking time equation mechanism is actuated by a time equation cam.
  • the time equation cam is rotated at the rate of one revolution per year from a date mechanism which can be simple or perpetual.
  • the simple calendar is a mechanism designed to indicate the day of the week, the calendar of the month, the month of the year or even the phases of the Moon, but which does not take into account the variation in the number of days in the month (months of 28, 29 or 30 days). In other words, the user of a watch with a simple date mechanism will have to make a manual correction every month which has less than 31 days. For example, on February 28 or April 30, manual intervention will be required.
  • the perpetual calendar mechanism it allows, like a simple calendar mechanism, to indicate the day, the calendar, the month and the phases of the Moon. But unlike a simple calendar mechanism, a perpetual calendar mechanism automatically takes into account the length of the months (28, 29 and 30 days), without manual intervention. A perpetual calendar mechanism therefore automatically takes into account leap years.
  • time equation cam 1 whose profile is determined by the difference, for each day of the year, between the average solar time or civil time and the true solar time.
  • This time equation cam 1 is driven in rotation at the rate of one revolution per year from a simple or perpetual calendar mechanism that comprises the timepiece.
  • the time equation cam 1 carries a month 2 disc which rotates at the same speed as it allows the position of this time equation cam 1 to coincide with the date indicated by the date mechanism that the solar time minute hand 4 indicates the exact offset between the minute of civil time and the minute of solar time.
  • the date mechanism simple or perpetual, can be of any known type and will not be described here in its entirety. It is sufficient, in fact, for a good understanding, to know that this date mechanism drives the cam of equation of time 1 at the rate of one complete revolution per year.
  • this date mechanism drives the cam of equation of time 1 at the rate of one complete revolution per year.
  • a date mobile 6 driving a hand 8 which indicates the date (from 1 to 31).
  • This date 6 mobile rotates at the rate of one complete revolution per month. It is actuated by the date mechanism and drives the time equation cam 1 via an intermediate date return wheel 10 which makes it possible to reverse the direction of rotation, and a reduction mobile 12 which makes it possible to reduce the speed of rotation from one complete turn per month to one complete turn per year.
  • the minute hand of solar time 4 is driven by a differential gear device 14 which has for respective inputs a gear train driving a minute hand of civil time 18, and a rake 20 which cooperates with the equation of time cam 1 (on the figure 1 , the rake 20 is shown in its two extreme positions, once in solid line, and the other time in mixed line).
  • the differential gear device 14 comprises at least one and, preferably, two planet gears 22 driven by the timer of the clockwork movement of the watch. These two planet gears 22 are capable of turning on themselves and of rolling on the internal toothing 24 of a time equation wheel 26.
  • the latter also has on its outer periphery a first toothed sector 28 by which it cooperates with a second toothed sector 30 which is provided with the rake 20 at one of its ends.
  • This rake 20 is subjected to the return action of a spring (not shown) fixed to the frame of the watch and which tends to apply a feeler 32 forming the other end of the rake 20 against the profile of the equation cam of time 1.
  • the gear for displaying solar time comprises a pinion for displaying solar time 34 placed in the center of the differential gear device 14.
  • This pinion for displaying solar time 34 meshes on the one hand with the satellite pinions 22, and on the other hand carries a wheel for displaying solar time 38 which meshes with a roadway 40 on the barrel of which is driven the minute hand of solar time 4.
  • This cog 38, 40 makes it possible to return the display of the solar minute to the center 42 of the clockwork movement of the watch, so that the minute hand of solar time 4 is concentric with the minute hand of civil time 18.
  • the time equation cam 1, the rake 20 and therefore the time equation wheel 26 are stationary.
  • the satellite pinions 22 are driven by the clockwork movement of the watch. They therefore rotate on themselves and roll on the internal toothing 24 of the time equation wheel 26, driving the pinion for displaying solar time 34 in rotation, which allows the minute hand of solar time 4 to rotate concomitantly with the minute hand of calendar time 18.
  • the difference between the minute hand of solar time 4 and the minute hand of civil time 18 therefore remains constant over a 24-hour period.
  • the time equation cam 1 pivots, driven by the date mechanism which moves the calendar from one day to the next.
  • the probe 32 which is in contact with the profile of the time equation cam 1 in turn rotates the rake 20.
  • This rake 20 by pivoting, drives the time equation wheel 26 in rotation.
  • the satellite pinions 22 being, during this short time interval, substantially stationary (they make a complete revolution on themselves in 1 hour), rotate on themselves by being driven in rotation by the time equation wheel 26, and in turn drive the solar time display pinion 34 so as to again exactly adjust the position of the solar time minute hand.
  • the walking time equation mechanism described above therefore makes it possible, using a minute hand from civil time and a minute hand from solar time, to display the time difference between the mean solar time and true time.
  • the differential gear device 14 is not located at the center 42 of the watch movement of the watch. So we have a construction which is not symmetrical, which is constructive.
  • This additional gear train takes up space and can be a source of failure.
  • EP 1,637,942 A1 discloses a mechanism for the equation of walking time controlled by a differential device in which the hour of civil time is produced by a timer mobile and which does not include a satellite mobile for multiplication.
  • the present invention aims to overcome the problems described above as well as others by providing a mechanism for equation of the walking time controlled by a differential gear device which is in particular more compact and therefore easier to integrate into a watch movement.
  • the subject of the present invention is a mechanism for the equation of walking time according to claim 1 appended to the present patent application.
  • the present invention provides a mechanism for the equation of walking time which is driven by a differential gear device provided with a reducing satellite mobile via which the minute canon of civil time drives a canon of hours of civil time. on which the hour hand of the civil time is chased, and of a mobile satellite multiplier via which the canon of the hours of the civil time drives a canon of the minutes of the true time on which the minute hand of the true time is chased.
  • the fact of proposing to integrate into the heart of the differential gear device the functions which make it possible to produce the hour of civil time from the minute of civil time, and the minute of true time from the time of civil time and a time equation cam, makes it possible to obtain a more compact differential gear device, the reducing and multiplying satellite mobiles of which are brought back to the center of the clockwork movement.
  • the differential gear device according to the invention is thus easier to accommodate in the timepiece movement which it equips, which makes it possible to reduce the size of the timepiece movement and to have more space for accommodating the other components of the movement.
  • the reducing satellite mobile and the multiplying satellite mobile rotate on themselves by describing a circular trajectory, preferably of the same radius, centered on the canon of the minutes of civil time.
  • the differential gear mechanism according to the invention has fewer components and is therefore more reliable. In addition, it has a general radial symmetry centered on the center of the movement, which facilitates assembly and arrangement.
  • the present invention proceeds from the general inventive idea which consists in equipping a mechanism for the equation of the working time with a differential gear device which is capable of indicating both the civil time by means of a hour hand of the civil time and a minute hand for civil time, and the minute for real time thanks to a second minute hand concentric with the hands for civil time.
  • the differential gear device has for respective power take-offs a moving part of a clockwork movement on the one hand, and a time equation cam on the other hand.
  • a multiplication function which makes it possible to pass from the minute of civil time to the hour of civil time and a multiplication function which makes it possible to pass from the hour of civil time to the minute of true time are integrated into the center of the differential gear device, which makes the working time equation mechanism more compact and therefore easier to arrange in the watch movement.
  • the object of the present invention is to integrate into a timepiece such as a wristwatch a mechanism for the equation of the walking time, that is to say a mechanism whose switching comprises two concentric minute hands , one indicating the minute of civil time and the other indicating the minute of true time.
  • the walking time equation mechanism according to the invention designated as a whole by the general reference numeral 44, comprises on the one hand a conventional turnout whose role is to indicate the civil time by means of a hand of the hours 46 and a minute hand 48, and on the other hand a true time minute hand 50, concentric with the civil time minute hand 48, and which indicates the minute of true time.
  • the wearer of the watch can, for example, end with a representation of the astrological symbol of the sun 52.
  • the exact position of the true time minute hand 50 for a given day is determined once in 24 hours, around midnight, then both calendar 48 and real time 50 minute hands move together, the gap between these two hands 48 and 50 remaining constant for the given day.
  • time equation cam 54 is fixed on a time equation wheel 56 which is driven at the rate of one complete revolution per year by a simple or perpetual calendar mechanism (not shown) that comprises the timepiece.
  • This date mechanism can be of any known type and will not be described here in detail. It is sufficient, in fact, for a good understanding of the invention, to know that this date mechanism drives the time equation wheel 56 on which is fixed the time equation cam 54 at the rate of one complete revolution per year.
  • the date mechanism includes a date wheel 58 which rotates at the rate of one complete revolution per month, driving a date indicator 104.
  • the time equation wheel 56 is driven by the date wheel 58 via an intermediate date return wheel 60 making it possible to reverse the direction of rotation, and a reduction mobile 62 which makes it possible to reduce the speed of rotation from one complete revolution per month to one complete revolution per year.
  • the real time minute hand 50 is driven by a differential gear device 64 which has respective inputs (see figure 3 ) a mobile 66 of a gear train driving the minute hand of the civil time 48 and a time equation lever 68 which cooperates with the time equation cam 54.
  • a cannon for the minutes of civil time 70 is driven by the mobile 66 of the gear train of the clockwork movement of the timepiece via a carriageway 72 secured to the minute cannon of civil time 70.
  • the cannon minutes of civil time 70 drives a reducing satellite mobile 74 formed of a first satellite wheel 76 and a first satellite pinion 78 secured to the first satellite wheel 76.
  • the reducing satellite mobile 74 is pivotally mounted around a first pin 80 driven into an upper differential frame 82 to which is attached a canon of the hours of civil time 84 on which the hours hand of civil time 46 is driven. Driven by the canon of the minutes of civil time 70 via the first satellite wheel 76, the first satellite pinion 78 rolls on a first internal toothing 86 of a first differential crown 88 which is carried by the clockwork movement and which is fixed .
  • the first satellite pinion 78 By rolling on the first internal toothing 86 of the fixed differential crown 88, the first satellite pinion 78 thus pivots the upper differential frame 82 and therefore the hour barrel of civil time 84 which is integral with the upper differential frame 82
  • a reduction of one twelfth is achieved between the minute of the civil time and the hour of the civil time and one thus obtains the display of the civil time.
  • the reducing satellite mobile 74 makes it possible, by a reduction of one twelfth, to go from the minute of civil time to the hour of civil time.
  • a multiplier satellite mobile 90 is formed by a second satellite wheel 92 and a second satellite pinion 94 secured to the second satellite wheel 92.
  • the multiplier satellite mobile 90 is mounted free around a second pin 96 driven out in the upper differential housing 82 with which the hours of calendar time 84 are integral.
  • the hours of civil times 84 and therefore the upper differential housing 82 rotate, they drive the second pin 96 and, consequently, the mobile satellite multiplier 90, the second satellite pinion 94 of which rolls over a second internal toothing 98 of a mobile differential crown 100 which will be seen below that it is engaged with the time equation cam 54.

  • the mobile satellite multiplier 90 makes it possible, by a multiplication by twelve, to go from the hour of civil time to the minute of true time.
  • the reducing satellite mobile 74 and the multiplying satellite mobile 90 rotate on themselves by describing a circular trajectory centered on the minute canon of civil time 70.
  • the reducing satellite mobile 74 and the mobile 90 multiplier satellite move on a circle of the same radius, centered on the canon of the minutes of the civil time, being angularly spaced.
  • the movable differential crown 100 is pivotally controlled by the time equation lever 68 provided with a feeler spout 106 by means of which the time equation lever 68 is in contact with the profile of the cam. time equation 54.

  • This time equation lever 68 is also provided with a first tooth 110 engaged with a second corresponding tooth 112 provided on the movable differential crown 100 to control the movement of the latter. It is in fact understood that at an instant close to midnight when the date mechanism changes date, it controls the advance of one step of the date wheel 58. During this brief instant when the date change occurs, the upper differential housing 82 and therefore the hour barrel of civil time 84 can be considered stationary.
  • the movable differential crown 100 drives the second satellite pinion 94 and therefore the second satellite wheel 92 which, in turn, meshes with the solar time minute cannon 102 on which the true time minute hand 50 is chased.
