Definitions

  • the present invention relates to an analog indicator device, in particular for a timepiece, more particularly to an indicator device comprising a rotary member, such as a dial, a part of a dial or a telescope, bearing indications such as numbers and / or graduation.
  • a rotary member such as a dial, a part of a dial or a telescope
  • bearing indications such as numbers and / or graduation.
  • the European patent application EP 1 345 094 describes a device similar to that according to the patent JP 2599344 but in which the pads have a plurality of eccentric rods on their underside which are guided in respective eccentric circular grooves.
  • This device has the disadvantage of being very sensitive to manufacturing tolerances. Indeed, for proper guidance of the rods in the grooves, and to avoid the risk of blockage, the rods and grooves must have very precise dimensions, especially as the grooves intersect.
  • the present invention aims to provide an analog indicator device including a timepiece that facilitates the reading of the indications carried by a rotary member while being simple and reliable.
  • an analogue indicator device comprising a rotary member comprising one or more housings in which are arranged rotatable on themselves one or more respective indicator members each carrying at least one indication, characterized in that it comprises in in addition to one or more pinions respectively integral with the indicator member (s) and engaged with a fixed toothing coaxial with the rotary member, the gear ratio between the fixed toothing and the pinion or gears being chosen so that the indication carried by the or each indicator member has the same orientation at specific angular positions of the rotary member.
  • the analog indicator device comprises several indicator organs bearing respective indications that have the same orientation.
  • the rotary member is for example a disc.
  • the determined angular positions are stable positions in which the rotary member is held by means of a spring.
  • the analog indicating device may comprise a manual control member for controlling the movements of the rotary member.
  • the present invention also proposes a timepiece comprising an analog indicator device as defined above, for example to indicate hours.
  • the timepiece may further include fixed indications for indicating the times of a first time zone and the analog indicating device may be used to indicate the times of a second time zone distinct from the first time zone.
  • the analog indicator device can be used to indicate a power reserve, the minutes, the day, the day of the week or the month.
  • a timepiece 1 such as a wristwatch, a pocket watch, a pendulum, etc., according to a particular embodiment of the invention, comprises in particular a dial 2 above which are mounted indicator hands 3.
  • the dial 2 comprises a fixed outer annular portion 4, a movable intermediate annular portion 5 and a fixed central portion 6, these three parts 4, 5, 6 having the axis, indicated by the reference numeral 7, of the Dial 2, around which the needles turn 3.
  • the fixed outer annular portion 4 carries indications of the hours 8, such as a graduation associated or not with numbers.
  • the moving intermediate portion 5 also bears indications of hours 9, in the form of four numbers "3", "6", “9” and "12" distributed at 90 °. These indications 9 are oriented in the same direction of reading, namely horizontal from left to right in the view of the figure 1 considered vertical.
  • the outer portion 4 and the central portion 6 of the dial 2 are the upper surfaces of an outer piece and a central piece, respectively, fixed to a plate 12 itself fixed to the movement of the timepiece (not shown ).
  • said central part is designated by the reference 11 and said outer part has not been shown.
  • the movable intermediate portion 5 of the dial 2 is defined by a rotating disc 13 guided around a scope cylindrical 14 of the fixed central part 11 and by indicator members 15 mounted on the disc 13 and bearing the indications 9.
  • the disc 13 is rotatable about the axis 7 between twelve stable angular positions regularly distributed.
  • the fixed and movable indications 8 and the needles 3 with which they cooperate serve to simultaneously indicate the local times of geographical locations located in two different time zones.
  • the fixed graduation 8 and the hour and minute hands are indicated the hours and minutes of the local time of a first time zone, typically the one where the user is located.
  • the indications 9 and the hour hand are indicated the hours of the second time zone and by the fixed graduation 8 and the minute hand are indicated the minutes of the second time zone.
  • the lever 16 serves to adjust the disk 13 to the angular position corresponding to the number of hours of offset between the first and second time zones.
  • each indicator member 15 consists of a disc 22 on the upper surface of which is indicated the indication 9 and which is extended centrally on the side of its lower surface by a stud 23.
  • the stud 23 passes through a hole 24 formed in the the thickness of the disk 13 and is guided in rotation on itself by a bearing 25, for example ruby.
  • a pinion 26 is fixed rigidly, for example driven, at the end of the stud 23 and thus forms with the indicator member 15 a rigid assembly rotatable relative to the disc 13 about a common axis of symmetry 27.
  • a coaxial ring 28 with the parts 11 and 13 is fixed rigidly, for example driven, around a bearing 29 of the fixed central piece 11, under the disc 13.
  • This ring 28 comprises at its periphery a toothing 30 which is engaged with the teeth of the pinions 26.
  • the ring 28 also has on its upper surface a bearing projection 31 on which the disk 13 rests, the latter being also retained on the side of its upper surface (dial side) by an overflow 32 of the fixed central part 11. Interposed between the pinions 26 and the disks 22, the disc 13 holds the indicator members 15 in the holes or housings 24.
  • the disc 13 When the disc 13 is rotated by the lever 16, it carries with it the indicator members 15 which, because of the meshing between the teeth of the pinions 26 and the fixed ring 28, rotate on themselves in the holes 24 in the same direction of rotation as the disc 13.
  • the indications 9 rotate relative to the disc 13 and relative to the fixed parts (plate 12, box, etc.) of the timepiece.
  • the gear ratio (ratio between the number of teeth or between the number of revolutions) between each pinion 26 and the ring gear 28 is chosen so that the indicator members 15 turn about themselves by one turn minus 30 ° (one turn minus 360 ° / 12) during the transition from a stable position to a stable consecutive position of the disc 13.
  • the indications 9 find the common orientation that they had before this movement, as shown to the figure 2 .
  • the indications 9 have the same common orientation, that is to say they are readable in the same direction, in all the stable positions of the disc 13, which facilitates the reading avoiding the user having to turn the head to read them.
  • This effect is obtained in a simple manner and without risk of blocking the disc 13.
  • the rotation of the indications 9 on themselves gives a playful and attractive aspect to the timepiece, this all the more more that the indications 9 rotate in synchronism, that is to say that the respective orientations of the indications 9 remain at all times identical to each other.
  • the toothing 30 of the ring 28 has 132 teeth and that of each pinion 26 has 12 teeth. These numbers of teeth can of course be modified, as long as the gear ratio mentioned above is respected. Alternatively, the gear ratio may be such that each pinion 26 rotates N turn (s) plus one turn minus 30 °, where N is an integer greater than or equal to 1.
  • the ring 28 could have a larger diameter and an internal toothing engaged with the pinions 26.
  • the pinions 26 and indicator members 15 would rotate on themselves in the direction opposite to the direction of rotation of the disc 13 and the gear ratio between each pinion 26 and the toothing of the ring gear 28 would therefore be chosen so that each pinion 26 rotates by N turn (s) plus 30 °, where N is an integer greater than or equal to 1
  • the internal toothing of the ring 28 comprises 156 teeth and the toothing of each pinion 26 comprises 12 teeth.
  • the indicator members 15 are four in number. They could of course be in different numbers, inferior or superior. For example, there could be twelve indicator bodies bearing the numbers “1" to "12", or a single indicator organ with the number "12".
  • analog indicator device according to the invention could be mounted directly on the movement stage.
  • the principle of the analog indicator device described above could be used in other applications than the display of a dual time zone, for example to display a power reserve, the hours, the minutes, the date, the day of the week or the month in cooperation with a fixed index of the dial.
  • a particular application might be to integrate this device into a perpetual calendar mechanism for simultaneously displaying the current calendar and the next calendar through a window, these two calendars having the same orientation.
  • the rotating disk 13 would be controlled by the movement of the timepiece, and no longer only by a manual lever, and could be moved instantaneously between discrete positions.
  • the gear ratio between the pinions 26 and the fixed toothing 30 would be N turn (s) - 360 ° / P for an external fixed toothing and N turn ( s) + 360 ° / P for an internal fixed toothing, N being an integer greater than or equal to 1 and P being the number of discrete positions of the disc 13. It is also clear that non-horological applications can be envisaged for the present invention.
