Definitions

  • the present invention relates to a timepiece including a display from 0 to 12 o'clock, a display minutes, a time zone display of two places located in two time zones separated from 180 ° from each other, corresponding to the hours displayed by said hour display, an AM / PM display to distinguish the hours preceding those following the passage of sun at the meridian, an indicator to indicate for which of the two time zones displayed the hours are those before or after passing the meridian, drive bodies step by step moving elements of said display the time and AM / PM indications and a correction toggle simultaneous time and time zone displays and the AM / PM indicator, which can move between two limit positions, and maintained in one of said positions limits by a return spring.
  • FR 2 752 628 relates to a watch of this type in which the hours are displayed on the one hand by a hand, on the other hand by a disc which indicates the local hours corresponding to those of different cities, on a 24-hour scale.
  • the representative cities of the different time zones are carried by a rotating disc.
  • a correction mechanism intended to change from one time zone to another, connects the 24-hour disc, the time zone disc showing the cities and the time switch so as to make 1/24 th of lap record of cities and hours of each correction.
  • Such a system makes it possible to know the local time of the different places on the planet looking at disc 24 hours and the corresponding cities.
  • One of the disadvantages of such a display mode comes from the fact that in the major part of the countries of the world, especially in all countries English speakers, people are not used to counting 24 hours a day. Even in other countries, generally, in everyday language, we speak more easily 2 o'clock in the afternoon than 2 o'clock for example, so that a watch displaying the hours on a 24 hour scale does not give an indication universally usual, even if it is understandable.
  • Another disadvantage is that with a division in 24 time zones, the angular space is only 15 °, so that in the case of a wristwatch, the indications of the cities belonging to the respective time zones is extremely small and therefore the indications must be written in very small print and are therefore difficult to read.
  • the object of the present invention is to remedy, less in part, to the aforementioned drawbacks.
  • the present invention relates to a timepiece of the aforementioned type, as defined by claim 1.
  • the essential advantage of the solution proposed by this invention lies in the fact that the correction does not result not directly from the pressure exerted on the pusher correction, but that it is produced by the winding of the spring and only if this arming is complete, that is, if the finger on the correction toggle is brought out of the teeth of the drive member not to no moving parts of the display in which it is engaged, passing beyond a tooth of this toothing. Yes pressure on the pusher is incomplete and the finger of the rocker does not pass beyond the tooth of the toothing of this step-by-step drive member of the movable elements display, the return spring disarms without driving the drive and without any correction being made occurs.
  • Another advantage comes from the fact that the hours are displayed on a twelve-hour scale and two time zones times distant 180 ° are displayed simultaneously, the display AM / PM and the indicator showing which time zone relates to these AM / PM indications, avoids any error in reading the time indications without having recourse on a 24 hour scale.
  • the timepiece illustrated in Figure 1 includes a classic movement 1 on which a plate 2 of the mechanism universal time display is reported and maintained by screws 3.
  • the watch movement 1 has, from usual way, a cog timer including a pavement 4 and a timer wheel 5.
  • the rest of the movement of watch itself is quite classic and has no need to be described, as it does not part of the invention and is not necessary for its understanding.
  • the connection between the pinion 5a of the timer wheel 5 and the barrel wheel 6 carrying the hour hand 7 (figure 2) is produced by a wheel 8 (figure 1) meshing with the pinion 5a of the timer wheel 5a, on which a disc 9 is fixed by screws 10.
  • This disc 9 carries a pawl 11 pressed by a spring 12 in the teeth in star of twelve teeth of a pinion 13 fixed under the wheel to canon 6 (figure 3). Thanks to this link between the cog of timer 4, 5 and the barrel wheel 6, this can be separated of this cog when changing time zones and find the angular position it occupied at the time correction, offset by a multiple of 30 ° after time zone change, when it is otherwise normally driven by the clockwork 4, 5, 5a.
  • the barrel wheel 6 is engaged with a wheel 14 carrying a drive finger 14a intended to come into engagement with each revolution of the wheel 14, that is to say every twelve hours, with a pinion in star 15 (figure 7) carrying a disc 16 on which are indicated alternately AM / PM (according to the Anglo-Saxon abbreviation meaning that it is hours before the passage from the sun to the meridian, respectively after this passage). These indications appear in a window 17 on the dial 18 ( Figures 2, 8-10) and change every twelve hours.
  • the timepiece described still has two additional displays, both independent of the gear train 4, 5, 5a, but which, when correcting the time zone must be kinematically interdependent of the hour hand 7 and the AM / PM disc 16.
  • These are a ring 19 provided with an internal toothing 19a on which is fixed a ring 20 bearing the names of different cities representative of the twenty-four time zones, arranged according to two concentric crowns. Cities diametrically opposite outer and inner crowns appear respectively in two counters 21, 22 arranged opposite twelve o'clock, respectively six o'clock on dial 18 (figure 2).
  • the outer crown cities located at 180 ° of a city from the inner crown are in two time zones 180 ° apart, so the hours indicated by the hour hand 7 correspond to hours before the sun goes to the meridian for one of the two cities and hours after passing the meridian for the other of these cities. Mention should also be made of the presence of a drive pin 19b which projects on the surface of the ring 19 and whose function will be explained thereafter.
  • an indicator consisting of a disc carrying arrows 23a is pivotally mounted on an axis 24.
  • the underside of this disc is integral with a pinion star toothing 25 positioned by a jumper 26.
  • the pinion 15 with star teeth fixed to the disc 16 is positioned by a jumper 27 (figure 7).
  • the ring 19 is guided on the plate 2 by rollers 29 engaged with its outer edge.
  • the internal teeth 19a of this ring 19 is engaged with a pinion 28 (FIG. 4) and this toothing 19a is positioned by a stressed jumper 30 by a spring 31.
  • the pinion 28 is integral and concentric a pinion 32 engaged with a pinion 33, integral and concentric of a correction star 34 ( Figures 3-7) positioned by a jumper 35.
  • This correction star 34 is intended to engage the barrel wheel 6.
  • FIG. 3 when it is positioned by the jumper 35, its teeth are outside of the trajectory of the toothing of the barrel wheel 6, of so that it can rotate freely.
  • the correction star 34 is in engagement with a rocker of correction 36 which is engaged, on the one hand with a spring 37 and, on the other hand, with an actuation lever 38 controlled by a pusher (not shown).
  • the correction lever 36 occupies the position illustrated by FIG. 5, position in which its drive finger 36a ( Figures 3 and 5) is engaged in the teeth of the correction star 34.
  • the indications appearing in the counters 21, 22 and 39 also do not change, only the indication AM, PM changing every twelve hours.
  • Figure 5 shows the mechanism at rest, every star tooth gears, 15, 25, 34 and toothing 19a being positioned by the respective jumpers, 26, 27, 30 and 35.
  • the correction rocker 36 In pressing the actuating lever 38, the correction rocker 36 from its rest position, illustrated in FIG. 5, at a second limit position illustrated by Figure 6. Going from the position of Figure 5 to that of Figure 6, the drive finger 36a of the correction flip-flop 36 encounter, at the end of its stroke, a tooth of the correction star 34, so that it moves slightly this star 34 of a fraction of its pitch. After the passage of finger 36a, the jumper 35 brings back the star correction 34 in its initial position, as can be see in figure 6.
  • correction flip-flop 36 In order for the correction to take place, it is therefore correction flip-flop 36 must reach the position illustrated by figure 6. At this moment, when the rocker actuator 38 is released, return spring 37 disarms by training the correction toggle 36. The training finger then moves the correction star 34 and the coaxial pinion 33 which is integral therewith with a pitch of the star 34.
  • Figure 7 illustrates the mechanism during this displacement and figure 9 shows the corresponding positions different displays.
  • the correction star 34 rotating 60 ° in the direction of arrow F drives the barrel wheel 6 by 30 ° in the direction of arrow F 1 .
  • the wheel 14 which is in a ratio of 1/1 with the barrel wheel 6 and its drive finger 14a also rotates 30 ° in the direction of the arrow F 2 . If this correction is made near the passage of the sun to the meridian, the drive finger 14a will move the disc 16 AM / PM by one step of the star pinion 15 in the direction of the arrow F 3 .
  • the barrel wheel 6 can move relative to the clockwork 4, 5, 5a ( Figure 1), without moving the minute hand m.
  • the pinion 33 secured to the correction star 34 drives the pinion 32.
  • the gear ratio is chosen so that the pinion 33 moves 60 ° in the direction of the arrow F, the pinion 32 moves 90 ° in the direction of the arrow F 4 , so that the pinion 28 drives the toothed ring 19 by 30 ° in the direction of the arrow F 5 .
