Definitions
- the present invention relates to a universal walking market. More specifically, the subject of the present invention is such a walking hoist which precisely displays the time at which the sun is at the zenith regardless of the position, in longitude, of 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.
- FIGS 1, 2 and 3 appended to this patent application illustrate the differential device according to the prior art to which applies the universal walking equation mechanism according to the invention.
- 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 shown in Figure 1 in its two extreme positions, once in full line and the other time in broken lines).
- the differential gearing 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 walking 1.
- the display gear of the solar time comprises meanwhile 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 pinions 22.
- a display wheel 38 which meshes with a roadway 40 on the barrel from which the minute hand of the solar time 4 is driven.
- This wheel 38, 40 makes it possible to reduce the display of the solar time to the center 42 of the watch movement of the watch, so that the minute hand of the solar time 4 is concentric with the minute hand of the civil time 1 8.
- the walking time equation mechanism just described works as follows.
- 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.
- 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 comprising a differential device whose first input is constituted by a roadway of the minutes of the civil time and of which a second input is constituted by a walking equation cam, the differential device outputting one minute of walking equation, the minute of the walking equation resulting in a true minute of running equation which, via a true equation timer, results in a true hour of walking equation, the minutes floor civil time resulting, via a mobile timer, a wheel of civil hours, a jumper, secured to the wheel of civilian hours, cooperating with a star of twelve teeth linked to an axis carrying a hand of the calendar hours, a spindle wheel being also integral with the axis, a shift and display gear coupled with the true equation timer to apply on time equation true walking offset related to the position in longitude of the user relative to the center of the time zone, the spindle wheel to apply forward or backward in steps of one hour to the wheel of the civil hours the difference between the calendar time at the location of the user and
- the present invention provides a universal walking time equation mechanism not only capable of displaying the gap between solar time and civil time, but still capable of taking into account the gap between solar time. and the civil time inherent in the user's longitude position relative to the center of the time zone.
- the equation mechanism of the universal walking time according to the invention makes it possible to display at any moment the difference in hours and minutes between the civil time at the location of the user's time zone and the solar time.
- FIG. 1 is a plan view of the equation of the walking time equation to which the equation mechanism of the universal walking time according to the invention applies;
- FIGS. 4A, 4B and 4C illustrate a first embodiment of the universal walking equation mechanism according to the invention
- FIGS. 5A, 5B and 5C illustrate a second embodiment of the universal walking equation mechanism according to the invention.
- the present invention proceeds from the general inventive idea of providing an equation mechanism of the universal walking time which, for the display of solar time, takes into account the difference between the civil minute and the solar minute, the difference in the longitude position of the user relative to the center of the time zone, and the deviation from any discrepancy between the civil time of the user's location and the official time in the center of the time zone; time zone.
- FIGS. 4A, 4B and 4C illustrate a first embodiment of the universal walking equation mechanism according to the invention.
- FIGS. 5A, 5B and 5C illustrate a second embodiment of the universal walking equation mechanism according to the invention.
- FIG. 4A is a schematic representation of a walking equation mechanism according to the prior art comprising a differential device 44 which has for respective inputs a roadway 46 driving a minute hand of the civil time 48 and a weather equation cam 50. 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 1, and -16 min 23 s on November 4.
- the width of a time zone is 15 °, which corresponds to a duration of one hour, so that the sun enters the time zone 30 minutes before the official time of the spindle and comes out 30 minutes after the official time of the spindle.
- the minute of walking equation 52 causes friction 54 (lanterning) a true minute of walking equation 56.
- This true minute of running equation 56 is distinguished from the minute of walking equation 52 in that it takes into account not only the difference, for a given day, between calendar time and solar time, but also the position in longitude of the user in the time zone.
- the true minute of running equation 56 in turn causes, through a timer of true equation 58, a true hour of running equation 60.
- a user-drivable train 62 is coupled to the true equation timer 58.
- the gear train 62 is coupled directly to the true minute of walking equation 56.
- This gear train 62 shifts the true minute and hour of equation respectively marching 56, 60 depending on the position in longitude of the user in the time zone.
- the gear train 62 carries one or two indications.
- a first wheel 64 of the train 62 has the indication ⁇ 7.5 ° of the offset of the position of the user relative to the center of the time zone (knowing that each time zone has 15 °) and, optionally, another wheel 66 of the gear train 62 may carry an East or West indication of the offset from the center of the time zone.
- the roadway 46 which carries the civil minute 48 drives, in a ratio of 1/1 2, via a mobile timer 68, a wheel of the civil hours 70.
- This wheel of the civil hours 70 carries a jumper 72 resulting in a star of twelve teeth 74 connected to an axis 76 carrying a calendar hour hand 78 and a spindle wheel 80 having the same number of teeth as the calendar hour wheel 70.
- the watch according to the invention is equipped with at least one winding stem (not shown) which, in a retracted position, allows the watch to be reassembled and which, in a first drawn position, makes it possible to adjust the date indication. .
- the winding stem makes it possible to adjust the difference between the civil time at the location of the wearer of the watch and the official time in the center of the spindle. time and, in a third position drawn T3, the winding stem allows the time setting of the watch, that is to say the setting of the watch at the time of the place where the user is located. the watch.
- the time setting of the watch is done by the winding stem in position T3 and via the mobile timer 68.
- the mobile of timer 68 acts on the mobile timer 68 to bring the minute civil 48 and civil time 78 for example at noon.
- the mobile of timer 68 causes the road 46 which, remember, is one of the inputs of the differential device 44. Therefore, the rotation of the roadway 46 causes the rotation of the minute of walking equation 52 which in turn causes the minute true of equation marchante 56 and the true hour of equation marchante 60.
- the time of the switching that is to say during the assembly of the various needles in factory, one makes sure of bring the date mechanism to one of the four days of the year when the difference between calendar time and solar time is zero.
- the true hour of equation marching 60 and the true minute of equation marching 60 also place at noon.
- the difference between the minute of the civil time and the minute of the solar time was successively programmed, then the difference related to the positioning in longitude of the user in the time zone, and finally the difference between the time where the watch user is and the official time in the center of the time zone.
- All that remains now is to set the calendar time of the watch to coincide with the time of the location of the time zone where the user of the watch is located. This setting is done by a new operation of the winding stem in position T3.
- we set displaying the civil minute 48 and the civil time 78 so that these hands display the civil time of the location where the user is.
- the true hour of walking equation 60 and the actual minute of moving equation 56 move in the same direction and of the same amount as the civil minute 48 and the civil time 78.
- the watch displays the civil time and the gap between the civil time and the true solar time.
- FIGS. 5A, 5B and 5C appended to the present patent application illustrate a second embodiment of the walking universal equation mechanism according to the invention.
- This second embodiment of the invention differs from the first embodiment of the invention illustrated with reference to FIGS. 4A, 4B and 4C only in that it is intended to drive a minute hand from true time.
- This true time minute handwheel 82 moves over a shift indicator disc 84 driven out of the carriage borehole of the running equation minute 52.
- This shift indicator disc 84 has the indication ⁇ 7, 5 ° the offset of the position of the user relative to the center of the time zone (knowing that each time zone has 1 5 °) and the East or West indication of the offset from the center of the time zone.
- the true time minute hand pointer 82 points to the zero mark of the shift indicator disc 84. It is also understood that the minute hand of time true 82 and the shift indicator disc 84 are shifted substantially ⁇ 15 min relative to the minute hand of the civil time 48 to indicate the deviation, 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 1, and -16 min 23 s on November 4.
- the minute hand of the true time 82 is actuated independently of the shift indicator disc 84 to program, by means of the shift gear wheel 62 and display, the offset in East or West longitude related to the user's position relative to the center of the time zone. For example, suppose we are on June 21st. At this date, we know that the minute of the civil time is two minutes ahead of the minute of solar time. Therefore, if the civilian time minute hand 48 points to the zero scale, the true time minute handpiece 82 and the offset indicator disc 84 will indicate an offset of -2 min.
- the user acts only on the minute hand of the true time 82 to bring it to the 4 ° position of longitude East on the shift indicator disc 84. Therefore, if the user is a 21 June at 4 ° East longitude relative to the center of the time zone, the minute hand of the civil time 48 will be zero, the zero of the shift indicator disc 84 will be shifted -2 min relative to the minute hand of the civil time 48 and the minute hand of the true time 82 will be offset by 4 ° east longitude relative to the indicator disc of offset 84, that is to say + 16 min. In the end, the minute hand of the true time 82 will be shifted +14 min relative to the minute hand of the civil time 48.
- the winding stem in the position T3 of the winding stem, it acts on the civil minute 48 and the civil time 78.
- the winding stem comprises a sliding pinion which comes to act through a first gear on the mobile timer 68.
- T2 position of the winding stem we introduce the shift between the time of the place where we are and the official time of the spindle.
- the sliding pinion of the winding stem acts via a second wheel on the spindle wheel 80.
