Definitions

  • the present invention relates to a world time timepiece comprising a date correction mechanism.
  • the correction mechanism makes it possible to correct the date according to the selected time zone.
  • World time timepieces can simultaneously indicate the local time where the user is located and in other time zones.
  • the Earth is divided into twenty-four time zones.
  • the first time zone is centered on the Greenwich Meridian and is generally referenced by the abbreviation UTC or UTC 0.
  • Local time in London called Greenwich Mean Time (GMT)
  • GTT Greenwich Mean Time
  • the time is one hour ahead or one hour behind when moving from one time zone to another depending on whether one is traveling east or west. For example, for the time in Switzerland, its offset from London is 1 hour, so Switzerland is at GMT+1.
  • the twenty-four time zones therefore extend along the circumference of the Earth between UTC + 12 and UTC -11 (in winter time).
  • This type of timepiece comprises a disc on which are indicated within twenty-four 15° sectors the names of twenty-four cities, each corresponding to a different time zone. For example, London is inscribed within a 15° sector of the disc and Geneva GMT+1 is inscribed within an adjacent sector. In general, this disc has a sector diametrically opposite the Greenwich sector and in which the city of Auckland (UTC+12) is indicated. A sector adjacent to that of the city From Auckland, Midway (UTC -11) is indicated. The meridian separating these two time zones implies a date change. When crossing this meridian from Midway to Auckland, the date must be moved forward by one day, while when crossing in the opposite direction, the date must be moved back by one day.
  • a universal timepiece does not have a date display or the date display is only linked to local time since the correction of the date in order to address the above-mentioned problem is complex to achieve, in particular the simultaneous and contradictory action on a date star in the above-mentioned particular case.
  • EP2790069 does offer a timepiece with twenty-four time zones and a date display mechanism capable of changing the date according to all possible time zone changes. This mechanism allows, in particular, to subtract a day from the date when a time zone change occurs between Auckland and Midway before 11 p.m., and to leave the date unchanged when a time zone change occurs between Auckland and Midway between 11 p.m. and midnight Auckland time.
  • the date display mechanism comprises a synchronization mechanism kinematically connected to the date mechanism and to a time zone mechanism.
  • This synchronization mechanism comprises a differential gear configured in particular so that an output wheel of the differential, depending on the combination of inputs, can perform one of the following operations: moving the date back one day, moving the date forward one day, the date remains unchanged.
  • the simultaneous rotation of an input star wheel by one step and a satellite wheel by one step leaves an output wheel, carrying the date hand in this case, stationary for a time zone change between Auckland and Midway occurring between 11 p.m. and midnight Auckland time.
  • the differential gear chain mentioned above has the disadvantage of causing play, requiring the addition of an additional jumper, designed to be activated at the same time as the main jumper.
  • the use of these jumpers significantly increases the consumption of the timepiece.
  • An aim of the present invention is therefore to propose a universal timepiece equipped with a date mechanism whose consumption is significantly lower than the aforementioned mechanism.
  • a universal timepiece comprising a city disc, a twenty-four-hour disc, an hour indicator, a disc support integral in rotation with the city disc, a driving member integral in rotation with the twenty-four-hour disc and arranged to be driven in rotation at the rate of one revolution in twenty-four hours, a time zone correction mechanism intended to actuate in rotation the city disc, the twenty-four-hour disc and the hour indicator at each time zone correction, and a date display.
  • the date display comprises an indication support comprising date indications, a date indicator, and a date correction mechanism comprising a trigger system. This is arranged to induce each day a first movement of the date indicator relative to the indication support in one direction.
  • the date correction mechanism further comprises an actuating element secured to the disc support for inducing a second movement of the date indicator relative to the indication support in an opposite direction when a time zone correction causes the date to move back.
  • the date indicator or the indication support is kinematically connected to a date star.
  • the trigger system is configured to actuate the date star in rotation in a first direction in order to induce said first movement.
  • the actuating element of the disc support is arranged to indirectly actuate the date star in rotation in a second direction opposite to the first direction in order to induce said second movement.
  • the indication support is in the form of a date disc.
  • the date indicator or the date disc is rotatably secured to a date crown meshing with a date wheel secured to the date star.
  • the date correction mechanism further comprises a correction wheel engaged with the date wheel and a correction star rotatably secured to the correction wheel.
  • the actuating element is arranged to be able to engage a tooth of the correction star to induce said second movement.
  • the trigger system comprises a twenty-four-hour wheel arranged to complete one revolution in twenty-four hours, a cam secured to the twenty-four-hour wheel, a lever arranged to cooperate with the cam in order to perform one jump per day and a finger for driving the date star in the first direction with each jump of the lever.
  • the finger is movably mounted on the lever to be disengaged from the date star when the date star is rotated in the second direction by the actuating element.
  • the trigger system further comprises a drive member pivotally mounted on the rocker and comprising the finger.
  • the drive member comprises a follower arranged to move in a groove along a closed path.
  • the groove comprises a first portion acting on the follower to pivot the drive member on the lever so that the finger can engage a tooth of the date star with each jump of the lever.
  • the groove includes a second portion acting on the follower to pivot the drive member on the lever so that the finger is clear of the date star from the end of the lever's jump until the next jump.
  • the time zone correction mechanism comprises a first lever arranged to actuate in rotation the driving member of the twenty-four-hour disc and the hour indicator, and a second lever arranged to actuate in rotation the support of the city disc.
  • the two levers are arranged to cooperate with a control member moving in a first direction and then in a second opposite direction in order to return to its initial position so that one of the levers can actuate one of said support and said driving member when the control member is actuated in the first direction and in that the other of the levers can actuate the other of said support and said driving member when the control member moves in the second direction.
  • the two rockers are connected to each other by a connecting member.
  • the city disc support is in the form of a first ring arranged to be actuated in rotation by one of the two rockers.
  • the driving member is in the form of a second ring arranged to be actuated in rotation by the other of the two rockers.
  • the second crown is engaged with a driving wheel arranged to be actuated in rotation by said other of the two rockers.
  • the second crown is furthermore kinematically connected to a wheel of a drive train.
  • This wheel is integral with a five-toothed star cooperating with a jumper so that the rotational actuation of the driving wheel drives the twenty-four-hour crown by one twenty-fourth of a turn and the hour indicator by one twelfth of a turn.
  • the timepiece according to the invention illustrated by the figures may in particular be a wristwatch or a table clock comprising a mechanism for displaying universal times and time zones known to those skilled in the art and described for example in CH693191
  • the timepiece also includes a date display and correction mechanism which will be described later and which allows the date to be triggered when a change of time zone causes a change of date at the passage of midnight.
  • the universal timepiece 10 conventionally comprises a first disc 12 called the city disc 12 on which the name of twenty-four cities is inscribed. Each city corresponds to one of the twenty-four time zones. For simplification, only GMT indications of the type GMT-4, GMT-5, GMT-4 have been shown corresponding to different time zones specific to different cities.
  • a second disc 14, called the twenty-four-hour disc 14, is arranged inside the city disc and has a numbering from 1 to 24 (only the numbers 7 and 8 are shown) so that the incrementation of the numbers is carried out in a clockwise direction to allow the time to be read opposite each city.
  • the twenty-four hour disc 14 is kinematically connected to the hour wheel carrying the hour hand of the display mechanism clock of the timepiece so as to rotate continuously in an anticlockwise direction at the rate of one revolution in twenty-four hours.
  • the twenty-four-hour disc 14 is secured to a driving member 16 arranged to be rotated by the movement at the rate of one revolution in twenty-four hours.
  • the time displayed by the hour and minute hands of a conventional world time timepiece corresponds to the current time of the city on the city disc 12 located at 12 o'clock relative to the dial of the timepiece. This time is referred to in this application as "local time”. To read the time in another time zone, it is sufficient to find the inscription of the city corresponding to this other time zone and read the number on the twenty-four-hour disc 14 located opposite this city.
  • the timepiece 10 further comprises a date display mechanism.
  • a date display mechanism This comprises in particular an annular disc 45 and a date indicator in the form, for example, of an aperture 48.
  • the disc 45 is arranged around the city disc 12 and comprises the numbering from 1 to 31 of the days of the month.
  • the date disc 45 is fixed while the aperture 48 is integral with a crown 46 meshing with a date wheel 50, the latter being integral with a date star 52.
  • the date disc may be integral with the crown while the aperture may be fixed, for example in the form of an opening in the dial, according to a more conventional date display.
  • the date star could comprise 31 teeth and carry a date hand.
  • the dial could include the numbering from 1 to 31 of the days of the month arranged for example along an annular zone on the dial concentric with the axis of rotation of the date hand. The presence of a date disc is not therefore not an essential characteristic of the date display mechanism.
  • the mechanism for displaying universal times and time zones allows the user to change the time zone and display the time corresponding to this new time zone by a time zone correction mechanism.
  • This mechanism includes a control member (not shown), for example a pusher that can be manually operated by the user a number of times necessary to bring the city of the new time zone and indicated on the city disc 12 to 12 o'clock relative to the dial of the timepiece.
  • This new time zone typically corresponds to the local time where the user is located.
  • the time zone correction mechanism is intended to rotate the 12 city disc and the 14 twenty-four hour disc counterclockwise for each time zone correction.
  • the hour hand is typically kinematically connected to the 14 twenty-four hour disc so as to be driven to make a one-hour jump clockwise for each time zone correction.
  • the city disc 12 is secured to a disc support 18.
  • This is in the form of a first crown 18 comprising a series of twenty-four teeth 19 distributed regularly over its external circumference.
  • the twenty-four hour disc 14 is secured to a second crown 16 arranged inside the first crown 18 coaxially therewith.
  • the second crown 16 comprises external teeth engaged with a wheel 22 of a motor train via two return wheels 26, 28.
  • the time zone correction mechanism comprises a first lever 34 arranged to actuate in counterclockwise rotation the crown 16 integral in rotation with the twenty-four hour disc 14, and a second lever 40 arranged to actuate in counterclockwise rotation the crown 18 secured to the city disc 12.
  • the first lever 34 is mounted to pivot around the axis A and comprises a part 38 actuable by the user by the control member such as a pusher via a lever (not illustrated).
  • This first lever further comprises an arm 36 whose end is configured to cooperate with a wolf-toothed wheel 32, under the effect of a spring (not shown).
  • the latter is mounted coaxially and integrally with a driving wheel 30 engaged with the crown 16.
  • the second lever 40 is mounted to pivot about the axis B and comprises a finger 42 arranged to engage between two teeth 19 of the first crown 18 and to push against one of these teeth in order to actuate the rotation of the city disc 12 in the counterclockwise direction.
  • the two levers 34, 40 are connected to each other by a connecting member 44.
  • this mechanism allows the twenty-four hour disc 14 and the city disc 12 to be actuated in a counterclockwise direction sequentially.
  • the actuation of the twenty-four hour disc 14 and the city disc 12 occurs in fact respectively during the "back and forth" movement of the control member, for example a push button, when it is actuated.
  • the wheel 22 of the motor train is integral with a five-toothed star 24 cooperating with a jumper 77.
  • the gear ratio between the wheel 22, the two intermediate wheels 26, 28 and the teeth of the crown 16 has also been determined so that the rotational actuation of the driving wheel 30 by the first lever 34 can drive the twenty-four-hour crown 16 by one twenty-fourth of a turn.
  • the star 24 ensures an indexed position of the twenty-four hour disc 14 at each change of time zone.
  • the second lever 40 allows the crown 18 to be rotated at any time by one twenty-fourth of a turn in the counterclockwise direction to bring the city corresponding to the new time zone and inscribed on the city disc 12 to 12 o'clock relative to the dial of the timepiece.
  • the timepiece 10 comprises a date correction mechanism comprising, on the one hand, a trigger system 60 kinematically linked to the crown 16 supporting the twenty-four-hour disc 14 and arranged to change the date every day at midnight, and on the other hand, an actuating element 20 secured to the crown 18 supporting the city disc 12.
  • This actuating element may be in the form, for example, of a finger 20 whose end is beyond the end of the teeth 19 of the crown 18. According to the example illustrated, this finger 20 is intended to engage a correction star 58 secured to a correction wheel 56 meshing with the date wheel 50 each time the correction of the time zone causes a change from Auckland to Midway, causing the date to be set back by one day.
  • the trigger system 60 is configured to actuate in rotation the date star 52 and the date wheel 50 of the date display mechanism in the clockwise direction in order to increment the date by one unit during the “go” of the control member while the date star 52 is actuated in a counterclockwise direction by the action of the finger 20 on the correction star 58 of the correction wheel 56 during the “come” of the control member when a time zone correction results in a date change.
  • the sequential actuation of the date star 52 one step clockwise and one counterclockwise during the back and forth movement of the control organ allows in particular to leave the date unchanged during a change of time zone between Auckland and Midway occurring between 11 p.m. and midnight Auckland time.
  • the trigger system 60 comprises for this purpose a twenty-four hour wheel 62 arranged to make one revolution in twenty-four hours and kinematically connected to the crown secured to the twenty-four hour disc, a snail-shaped cam 64 secured to the twenty-four hour wheel 62, a lever 66 arranged to cooperate with the cam 64 via a feeler 68 and a lever spring (not shown) acting on the lever 66.
