Definitions

  • the invention relates to a device for indicating the time, such as that a watch, comprising a case provided with a background and a dial, analog time display means, motor means, and a train gears for transmitting the movement of the motor means to said display means.
  • time indication devices such than a digital watch or clock that displays directly the time for different time zones, the time differences being programmed into these digital devices so that by the simple choice of a country or a specific zone, the corresponding time is displayed automatically.
  • Document US-3,633,354 relates to a watch allowing to indicate the time simultaneously from two different places due to the presence of two small hands to indicate the hours, the angular position is adjusted independently by two systems of ordered.
  • the invention therefore aims to provide a device for indicating the time of the type which was indicated previously, which can be set to several time zones by a simple and safe maneuver, not risking not affect the time setting setting of the device and allowing display, by means of a marker, the time zone corresponding to the time indicated by the device.
  • the time indication device is characterized in that said dial has a window and in that said device further comprises a crown movable in rotation around a geometric axis, placed behind the dial and carrying at least two marks separated by an angle ⁇ and positioned radially so that each of said marks can appear through the window in an angular position of said crown corresponding to a time zone indicated by said associated reference mark, and control means unique able to rotate, on the one hand, return means of setting the time connected to said gear train, in a first position control means and, on the other hand, the crown, in a second position of the control means, in that said gear train comprises a first mobile forming a satellite whose axis is integral with the crown and in that said gear train is shaped so that the rotation of the crown of said angle ⁇ generates, by means of said train gears, a rotation of said display means corresponding to the time difference between the two time zones indicated by said markers.
  • the gear train is shaped to allow rotation of the crown in both directions, the time difference can then be positive or negative.
  • the crown changes, on the one hand, by train gears, the position of the analog time display means, that is to say the time indicated by said device, and, on the other hand, by the appearance of another marker across the window, the time zone displayed on the dial, associated with this marker and corresponding to the new time indicated.
  • control means comprise a control rod capable of to be moved in longitudinal translation between said first position allowing to rotate said return setting means to the time and said second position allowing to rotate said crowned.
  • said means for returning the hour present a vertical wheel movable in rotation around an axis horizontal, meshing with the bottom wheel of the second mobile and being able to mesh with a vertical gear wheel located at the distal end of said control rod, in said first position of the control rod ordered.
  • the lower surface of the periphery of said crown is provided with teeth turned opposite said bottom and capable of cooperate with the teeth of a toothed wheel belonging to said means of ordered.
  • the device for indicating the time shown on the Figures 1 to 8 can be produced, depending on the dimensions used, in the form a watch or a pendulum without modifying the description which go follow.
  • This device for indicating the time 10 comprises a case 12 containing the mechanism, this housing 12 comprising a bottom 14, a wall cylindrical lateral 16 and being delimited in the upper part by a dial 18 at the upper surface of which we find all the inscriptions necessary for the time reading such as whole numbers in Roman numerals or in Arabic numerals (reference 20) as well as fancy names or decoration patterns.
  • the device 10 is provided with means analog time display in the form of a large hand 22 for the indication of the minutes and a small hand 24 for the indication for hours, these two hands 22, 24 being mobile in rotation around the same geometric axis (X0, X0 ').
  • the large needle 22 is integral with the upper end of a material axis 26 whose lower end is integral with a center gable or roadway 28. This roadway 28 meshes with an input wheel 30 whose axis is connected, via a friction system 32, to motor means 34.
  • These motor means 34 may be of a nature diverse.
  • the motor means 34 consist of a motor step by step controlled by an integrated circuit, itself powered electrically by means of a battery and subjected to the pulses of a oscillator or quartz.
  • the small hand 24, which makes a full turn of the dial in twelve hours, is driven indirectly, by the same motor means 34 with a speed ratio of 1/12 compared to the large needle 22.
  • This is produced by a gear train 36 composed of three stages 36a, 36b and 36c and connecting the roadway 28 to a cannon wheel 38.
  • the cannon wheel is integral with the lower end of a bearing 39 mounted idly around the axis central 26 and the upper end of which protrudes above the dial 18, is integral with the small needle 24 which is placed under the large needle 22.
  • the motor means 34 drive in rotation the input wheel 30 meshing with the roadway 28, or pinion of center, at a speed ratio equal to 1, the roadway 28 and the wheel inlet 30 having the same diameter.
  • the roadway 28 meshes with another toothed wheel 41 of larger diameter forming the lower wheel of a second mobile 40 rotating around an axis (X1, X1 ') fixed relative to the central axis (X0, X0').
  • the second mobile 40 also includes an upper wheel 42 surmounting the lower wheel 41 and belonging to an intermediate stage 36b of the gear train 36.
  • This upper wheel 42 meshes with a connecting wheel 46 mounted madly around the central axis 26 and meshing with a pinion 51 forming the lower wheel of a first mobile 50 whose axis support material 54 is integral with a crown 60.
  • the upper wheel 52 of the first mobile 50 meshes with the barrel wheel 38 of so that the rotational movement of the motor means 34 is transmitted up to the small needle 24 with a ratio of 1/12 between the barrel wheel and pavement 28, that is to say between the upper floor 36c and the lower floor 36a of gear train 36.
  • the first mobile 50 is mounted in rotation about an axis geometric (X2, X2 ') which is, like the axis (X1, X1') of the second mobile 40, parallel to the axis (X0, X0 ').
  • axis geometric (X2, X2 ') is, like the axis (X1, X1') of the second mobile 40, parallel to the axis (X0, X0 ').
  • the axis (X2, X2 ') is not fixed relative to the axis (X0, X0') but is movable rotating around the axis (X0, X0 ') because it follows the angular displacement of crown 60.
  • the time indication device 10 also includes control means 70 allowing the time setting of the device 10 or jet lag.
  • these control means 70 are unique and include a rod control 72 horizontal, the proximal end of which protrudes from the housing by an opening disposed at the side wall 16, a head grip 74 being fixed to this proximal end.
  • the distal end of the control rod 72 carries a toothed wheel 76 of axis (Y0, Y0 ') horizontal and perpendicular to the axis (X0, X0 ').
  • the control rod 72 is carried by a U-shaped stirrup 80 whose ends form a landing for the rod 72, two compression springs 82 each extending between the internal face of one of the legs of the stirrup 80 and a stop rib 84 annular placed around the control rod 72. These springs 82 are identical and tend to bring the control rod 72 into a position rest in which the stop rib 84 is centered relative to the two branches of stirrup 80.
  • time-setting return means consist of a vertical return wheel 86 movable in rotation around a horizontal axis (Y1, Y1 ').
  • the deflection wheel 86 has a double system of teeth for meshing with, on the one hand, the toothed wheel 76 and, on the other share, the lower wheel 41 of the second mobile 40.
  • the user can thus, through the train gears 36, simultaneously rotate the large needle 22 and the small hand 24 for resetting the device 10, the resistant torque developed by the pavement 28 being sufficient to disengage the wheel input 30 of the motor means 34 by eliminating the effect of the system at friction 32.
  • the control rod 72 In a second extreme stop position, corresponding to a retracted position, the control rod 72 kept pulled by the traction exerted by the user on the gripping head 74, allows the toothed wheel 76 to mesh with a toothing 61 arranged at the lower surface of the periphery of the crown 60, facing the bottom 14 of the housing 12. It is in this withdrawal position that the control rod 72 allows for an angular offset of the crown 60 resulting in a jet lag, that is to say the rotation of the only small hand 24, as described below.
  • the position of the crown 60 is identified by the display of marks 62 carried on the upper surface of the crown 60, one of these marks 62 which can be viewed through a window 19 cut out from the dial 18 at the same distance from the axis (X0, X0 ') as the pins 62.
  • the marks 62 (A, B, C ...) are spaced from each other by the same angle ⁇ .
  • this time difference may be done in both directions.
  • This advantageous arrangement is made possible due to the fact that the crown 60 and all the cogs of the train gear 36 can rotate in both directions which optimizes order handling regardless of the number of hours offset that you want to apply to the device.
  • this time difference can correspond to any number of hours desired.
  • the crown can be rotated more than one turn to obtain the jet lag desired.
  • FIGS. 1 to 8 presents three references 62 (A, B and C) each corresponding to three adjacent time zones which can correspond to the three time zones present within the Europe of so that the device illustrated can constitute a watch usable in any the European territory, each of the landmarks 62 (A, B, C) corresponding to one of these time zones and can be replaced by the initials of a country the corresponding time zone.
  • the device 10 includes a stabilization system 90 cooperating reversibly with the crown, in the positions of crown 60 corresponding to the display of one of the markers 62 through the window 19.
  • this system of stabilization 90 includes a ball 92 mounted on a spring 94 placed vertically in a tube 96, the opening of which is oriented in the direction of the crown.
  • a series of depressions 98 is located on the lower surface of crown 60 along a circle concentric with crown 60, the depressions being regularly spaced at an angle equal to the angle ⁇ .
  • the compression spring 94 keeps the ball in abutment against the crown 60 so that when the ball faces a depression 98, the ball 92 is partially housed in this depression 98.
  • the crown remains then stable in this angular position as long as the user does not exercise sufficient torque on the control rod 72 to overcome the compressive strength of spring 94.
  • the device 10 which has just been presented can also be used for jet lag which, instead of coming from a time zone change, comes from the time difference between the time summer and winter time.
  • control means 70 may have a shape other than that of the control rod 72 and can also be in the form of two separate control systems, one for setting the time and the other for the time difference created by the angular movement of the crown 60.
  • the device described above can also be adapted for the incorporation of an additional needle for the indication of seconds via an additional gear stage, preferably placed above the upper stage of the gear train 36.
