Definitions

  • the present invention relates to a movement for a timepiece comprising an annular module for indicating time information.
  • the time information is usually indicated by hands, generally thin and of various shapes, which move on a dial.
  • Other achievements offer more original displays, in particular based on peripheral rings around a dial.
  • EP3189178 describes a mechanical movement for a timepiece comprising, a plate, an annular module circumferentially surrounding the plate, the module comprising a movable ring and mounted to be rotated about its axis by a bearing means, the movable ring carrying a rotary indicator, the rotary indicator being an added part of which a first part fixed to a crown arranged on the mobile ring is flat and parallel to a plane defined by the crown and a second protruding and curved part, said second part, in shape of a point, being oriented towards the center of the crown, the crown comprising a housing for receiving one end of the first part of the rotary indicator.
  • the movement comprises a drive train arranged to drive the mobile ring in rotation according to a speed of rotation so that during its training, the rotary indicator displays time information in hours, minutes or seconds.
  • GB2243000 discloses an analog watch having a pair of bezel rings, rotatably mounted on the watch case around the edge of the watch dial, each bezel ring individually rotatable separately from the other, and the rings having means indicators for allowing a user to adjust one ring relative to the dial to indicate either a particular hour or a particular minute and to adjust the rings relative to each other to indicate the other a particular minute or d a particular time, respectively.
  • the object of the present invention is to propose a movement for a timepiece comprising an annular module to indicate simplified and more easily readable time information.
  • a movement for a timepiece includes a first and a second coaxial ring circumferentially surrounding a movement.
  • the first and second rings are movable and mounted to be rotated about their axis by rolling means, each ring carrying a rotary indicator.
  • the movement further comprises two gear trains arranged to each rotate the first ring according to a first speed of rotation imparted by the clockwork movement and the second ring according to a second speed of rotation imparted by the clockwork movement, so that during their drive around the periphery of the movement, the rotary indicator of the first ring displays a first information and the rotary indicator of the second ring displays a second information different from the first information.
  • the first and the second ring are nested one inside the other, the first ring surrounding the second inner ring, the first ring comprising a skirt on its upper part, the skirt being arranged to cover the upper part said second ring, so that only the rotary indicator of the second ring is visible but not the second ring.
  • the indicator of each ring is flat and parallel to a plane defined by the movement. According to this embodiment, the watch crystal can therefore be closer to the indicators of each ring and allows the timepiece to be thinner than usual.
  • the rotary indicator of the second ring is arranged to extend beyond the rotary indicator of the first ring when the two rotary indicators are superimposed.
  • the rotary indicator of the second ring is arranged to extend beyond the rotary indicator of the first ring when the two rotary indicators are superimposed.
  • the first and second ring are arranged to be driven from the floor of the movement or from a minute wheel set of said movement, at its center, and via said two separate gear trains.
  • the first ring comprises an internal peripheral recess
  • the second ring comprises a peripheral recess external
  • the peripheral recesses being arranged to receive a ball bearing ensuring the rotation of the second ring relative to the first ring.
  • each ring comprises internal toothing arranged to each be driven by a gear train.
  • the first information and/or the second information indicates time information for hours, minutes, seconds, a power reserve, a date.
  • the third piece of information indicates time information for hours, minutes, seconds, a power reserve, a date.
  • the invention relates in particular to a timepiece comprising such a movement.
  • a movement for a timepiece comprises a first and a second coaxial ring 1, 2 circumferentially surrounding a movement 3.
  • the first and second ring 1, 2 are movable and mounted to be rotated about their axis by means of bearing 4, 5.
  • each ring 1, 2 carries an indicator 6, 7 (see figure 2 ) rotary.
  • the movement further comprises two gear trains 8, 9 arranged to each drive in rotation the first ring 1 according to a first speed of rotation imparted by the clock movement and the second ring 2 according to a second speed of rotation imparted by the clockwork movement, so that during their drive around the periphery of the movement 3, the rotary indicator 6 (see figure 2 ) of the first ring 1 displays a first time information of the hours and the rotary indicator 7 (see figure 2 ) of the second ring 2 displays a second time information of the minutes.
  • the first and the second ring 1, 2 are nested one inside the other, the first ring 1 of the hours surrounding the second internal ring 2 of the minutes, the first ring 1 of the hours comprising a skirt 10 on its upper part, the skirt 10 being arranged to cover the upper part 18 of the second minute ring 2, so that only the rotary indicator 7 (see picture 2 ) of the second ring is visible when the watch is operational but not the second ring 2. Thanks to this overlapping of the rings, the reading of the time is original, simplified without having to increase the diameter of the watch case.
  • the indicators 6, 7 of the hour ring 1 and the minute ring 2 are flat and parallel to a plane defined by the movement 3 (see figure 1 ).
  • the rotary indicators of each ring have different dimensions.
  • the rotary indicator 7 of the second ring 2 is arranged to extend beyond the rotary indicator 6 of the first ring 1 when the two rotary indicators 6, 7 are superimposed. Thereby, as for watches with conventional hands, it is easier to distinguish one rotary indicator from the other.
  • the movement (not shown for greater clarity) comprises a third coaxial ring 14 carrying a rotary indicator 15, flat and parallel to a plane defined by the movement to display a third time information of the seconds.
  • the rotary indicator 15 of the third ring 14 of the seconds is arranged to extend beyond the rotary indicators 6, 7 of the first ring 1 of the hours and of the second minute ring 2 when the two rotary indicators 6, 7 are superimposed.
  • each ring 1, 2, 14, rotates at a different rotational speed, i.e. one revolution per minute for the 14 seconds ring, one revolution per hour for the 2 minutes ring and one revolution every twelve hours for the hour ring 1.
  • the third ring 14 is internal to the first and second coaxial rings 1, 2 and is arranged to be driven in rotation by a third gear train.
  • the first and second ring 1, 2 are arranged to be driven, at its center, and via said two separate gear trains 8, 9.
  • the first ring 1 comprises an internal peripheral hollow 11
  • the second ring 2 comprises an external peripheral hollow 12
  • the peripheral hollows 11, 12 being arranged opposite to receive a ball bearing 13 ensuring the rotation of the second ring 2 with respect to the first ring 1.
  • the first ring 1 comprises a second internal peripheral hollow 19
  • the movement 3 comprises an external peripheral hollow 20
  • the peripheral hollows 19, 20 being arranged opposite to receive a ball bearing 21 ensuring the rotation of the first ring 1 with respect to movement 3.
  • each ring 1, 2 comprises internal toothing 16, 17 arranged to each be driven by a gear train 8, 9.
  • a watch movement based on concentric rings each driven by a separate gear train makes it possible in particular to simplify the reading of the time and to free up a dial space which becomes a display area other than the time display.
