Definitions

• the invention relates to a timepiece equipped with a time zone indicator device for timepieces. Background of the invention
• Watches for indicating the time in one or more different time zones have existed for a long time and generally include complicated mechanisms. Typically, these watches include an additional hand to indicate the time in another time zone chosen by the wearer, which is not practical to adjust and / or correct or set the time in case of stop the watch.
• the document CH 685 584 attempts to remedy this problem by proposing a watch having an indicator of the hours provided for performing a tour in twelve hours and indicating the time under one of the time zones, and a minute indicator provided for performing a revolution in one hour, and comprising a movement directly causing the minute indicator, and a rotating member indicating at least two time zones and manually rotatable.
• the movement is rotatably mounted in a box comprising, engaged between the movement and the time zone indicator member, a first gear train and a second gear train for moving the hour and minute hand when the movement is rotated.
• the invention particularly aims to overcome the various disadvantages of these known techniques.
• an object of the invention is to provide a watch with a time zone display device allowing an intuitive and simplified change between the different time zones.
• Another object of the invention is to provide a watch with a time zone display device that is simple and inexpensive to implement.
• the first housing is rotatable in a second housing around an axis of rotation coinciding with the axis of rotation of the hours and minutes indicators, so that a rotation of the first housing in the direction time or counterclockwise relative to the second housing allows you to choose a time zone and indicate the time of the chosen time zone.
• the object of the present invention by its various functional and structural aspects described above, makes it possible to obtain a watch with a relatively simple time zone indicating mechanism while providing an easy and intuitive adjustment.
• the second housing comprises an upper portion and a lower portion secured together so as to encircle the first case, the upper part or the lower part receiving horns to attach a bracelet;
• the first housing respectively comprises a shoulder on its upper part and its lower part, each shoulder being arranged to cooperate with an opening formed in the upper part and a lower part of the second housing;
• the timepiece comprises means for locking the first housing with respect to the second housing;
• the locking means comprise at least one ball pawl cooperating with a hole;
• the second housing comprises, at each horn, a hole for allowing the passage of the ring during the rotation of the first housing relative to the second housing;
• the second housing is perforated on its side portions, upper and lower, so as to access the crown;
• the time zones are indicated on the bottom of the first housing, or on the edge of the first housing, or on the flange of the first housing;
• the hour indicator and the minute indicator are formed by two separate and superimposed disks, the hours disk supporting a needle to indicate the time;
• FIG. 2 is an exploded view of the first case of a timepiece according to the invention.
• Figures 3a and 3b each illustrate a separate embodiment for displaying time zones
• FIGS. 4a and 4b are respectively front and bottom views of a timepiece according to the invention displaying the time in London;
• FIGS. 5a and 5b are respectively front and bottom views of a timepiece according to the invention displaying the time in Moscow;
• FIG. 6 is an exploded view of the first case of a timepiece according to the invention according to another embodiment. Detailed Description of the Preferred Embodiments
• the watch comprises a usual movement, fitted into a first casing 1, the casing comprising a dial 3 surrounded and surmounted by a flange 2, an ice-cream surmounting the flange 2, and a flange 4 surrounding the ice to form a shoulder 40 on the upper periphery of the first housing 1.
• the nested movement can it may be a mechanical movement or a quartz movement or an electromechanical movement, the movement being arranged to cause an hour indicator 6 and a minute indicator 7.
• the hour indicator 6 performs a turn of the dial in twelve hours
• a twenty-four hour display the hour indicator 6 performs a dial revolution in twenty-four hours.
• the watch also comprises a second housing 10 having a lower portion 12 screwed to an upper part 1 1, the upper part comprising horns 1 10 to be able to attach a bracelet.
• the first housing 1 is rotatably mounted in the second housing 10.
• the horns can also be supported by the lower portion 12 of the second housing 10.
• the first housing 1 comprises respectively on its upper part and on its lower part, a flange 4, 4 'and a shoulder 40, 40', each assembly forming a peripheral annular flange arranged to cooperate with a circular opening formed in each of the upper parts 1 1 and lower 12 of the second housing 10.
• the first housing 1 is thus maintained in the second housing 10 so as to allow only a rotation of the first housing 1 about a coinciding axis A with the axis of rotation of the indicators of hours 6 and minutes 7.
• the first housing 1 comprises sections 8 on its edge, each section 8 receiving a time zone.
• the flange 2 which receives the different time zones, which may be twelve or twenty-four, for example.
• the spindles are displayed on the bottom of the first housing 1, the bottom being visible through the lower part of the second housing 10.
• each spindle includes a + or - sign so that the wearer can determine whether it is day or night in the selected spindle.
• the indicator indicating the time zone must be integral and rotate with the first housing 1, the time displayed being that of the spindle at noon on the first housing 1.
• a marker on the fixed part, namely the second housing 10 could for example be an inverted triangle, an arrow or a conventional index.
• locking means are provided between the first housing 1 and the second housing 10. More specifically, the locking means comprise at least one ball pawl 41 disposed at the shoulder 40, 40 'of the first housing 1, this ball pawl 41 being arranged to cooperate with hemispherical holes 121 formed along the periphery of the lower and upper portions of the second housing 10. According to the embodiment shown, there are twelve holes 121 regularly distributed and spaced 30 ° so that a rotation of a notch corresponds to an offset of +/- 1 hour. In the case where the watch has a display of twenty-four hours, there are obviously twenty-four holes 121.
• Such a spring blade device comprises a leaf spring 42 disposed in grooves formed at the shoulders 40 and 40 'of the first housing 1, each groove having a stop 44 for keep the leaf spring 42 in place.
• the spring blade 42 comprises at least one tooth 43 arranged to cooperate with grooves 122 formed in the upper and lower parts of the second housing 10.
• the hour indicator 6 is formed by a transparent disk supporting a triangle 60 indicating the current time on the dial which bears no numeral for the hours.
• Another disc forming the minute indicator 7 is mounted on the hour disc 6, the minutes disc having an opening 70 showing the current minutes on the dial, the minutes being this time displayed on the dial 3 digitally .
• the dial 3 comprises two portions, one without numerical indication for the hours, and the other with numerical indications for the minutes. Such a display mode makes it possible to rotate the housing 1 without worrying about a shift of the minute indicator 7 during a time zone change.
• the second housing 10 comprises, at the level of each horn 1 10, a recess 11 to allow the passage of the ring 5 during the rotation of the first housing 1 in the second housing 10. more, the second housing is perforated on its side portions, upper and lower, so as to access the crown 5 easily.
• the wearer of the watch wants to know the current time in a specific time zone, he simply turns the first housing in the direction hourly or counterclockwise. For example, in the case where the carrier is in the time zone of London 100 as shown in Figures 4a and 4b, and wishes to display the current time in Moscow, it is sufficient to bring the time zone indication Moscow 101 at noon on the first housing 1, which corresponds to three offsets and moves the crown 5 from three hours to 6 hours. The passage of the current time from one time zone to another is therefore greatly facilitated and simplified with this watch.
• the bearer For any change in the time, for example to change from daylight saving time to winter time or vice versa, the bearer must position himself on the London time zone and then choose the time zone to display the chosen time of the spindle.
