Definitions

  • the invention relates to a watch calendar device. It also relates to a watch movement comprising such a watch calendar device. Finally, it relates to a timepiece, in particular a wristwatch, comprising such a horological calendar device or such a movement.
  • the movement referenced Rolex 3255 which includes a calendar device intended to display an indication of the dates, as well as an indication of the days of the week.
  • a day indicator is arranged on the outer periphery of a date indicator, so as to provide a written indication of the days.
  • Such an arrangement requires a superposition of the day and date indicators on two separate planes.
  • the disc bearing the day indications is provided with windows within which the date indication may appear.
  • Such a solution provides excellent reading comfort, but a small axial shift in the day and date indications can be observed.
  • the movement referenced ETA 2836 which also includes a calendar device intended to display an indication of the dates, as well as an indication of the days of the week.
  • the date and day indicators are arranged on a single plane. Such an arrangement is nevertheless made possible by the fact that the day indicator is arranged on the inner periphery of the date indicator.
  • Such a solution is not optimal insofar as it does not make it possible to provide an indication of the days in full because of the too small area of the days indicator, which explains the fact that the indication of days is here abbreviated.
  • the day indication is duplicated, which can make the setting of the day indication not very ergonomic.
  • the object of the invention is to provide a calendar device making it possible to improve the calendar devices known from the prior art.
  • the invention proposes a calendar device whose reading of the indications of the days in words and of dates is easy and whose display quality perceived by the user is improved.
  • a calendar device according to the invention is defined by claim 1.
  • a watch movement according to the invention is defined by claim 13.
  • a timepiece according to the invention is defined by claim 14.
  • the timepiece is for example a watch or a wristwatch.
  • the timepiece comprises a watch movement, for example an electronic or mechanical movement 200, in particular an automatic watch movement.
  • the timepiece may also include a timepiece assembly, in particular a watch case intended to contain the movement.
  • the first and second discs are arranged so that the first and second faces are coplanar. In other words, indicators or date indications and the indicators or day indications are in the same plane or substantially in the same plane.
  • the first and second discs are also configured so that the second face is arranged around the first face and outside the first face.
  • the first face comprises at least a first disc crown and the second face comprises at least a second disc crown surrounding the first disc crown, outside this first crown.
  • planar faces we mean that the distance between the two faces or the distance of two planes passing through the two faces, measured along the axis A, is less than or equal to 80 ⁇ m, or even less than or equal to 60 ⁇ m, or even less than or equal to 40 ⁇ m.
  • the calendar device comprises at least a first date indicator 10 which is arranged on the first disc 1.
  • the at least one first indicator preferably comprises 31 first indications. These indications are for example numbers, in particular 1 to 31, and are preferably arranged at regular angular interval on the first disc around the axis A.
  • the at least one first indicator is advantageously placed on the first face of the first disc .
  • the at least one first indicator can be engraved and / or padprinted on the first disc.
  • the calendar device comprises at least one second indicator 20 for the days which is arranged on the second disc 2.
  • the at least one second indicator preferably comprises 7 indications. These second indications are for example strings of characters, in particular alphanumeric strings of characters, in particular alphabetic strings of characters, in particular the names of the days of the week in one language or another, for example in French, in English, Spanish, German, Russian, Chinese, or Japanese. These second indications are preferably arranged at regular angular intervals on the second disc around the axis A.
  • the at least one second indicator is advantageously placed on the second face of the second disc.
  • the at least one second indicator can be engraved and / or padprinted on the second disc.
  • the first disc 1 comprises a first internal toothing 1a comprising 31 teeth.
  • the first disc is angularly indexed by a spout 7a of a first jumper 7.
  • This first jumper preferably cooperates with the first toothing 1a to ensure the indexing of said disc. Every 24 hours, one of the teeth of the teeth 1a is provided to be actuated by a first finger 3a of a mobile 3 calendar trainer, so as to allow a drive of the first disc 1 of the dates, and thus allow a update of date indication.
  • the mobile 3 calendar trainer is also provided for actuating a mobile 4 for the days, which is kinematically linked to the second disc 2 for the days.
  • the mobile 4 of the days comprises a first wheel 40 provided with an external toothing 40a comprising 7 teeth.
  • the day mobile is angularly indexed by a spout 8a of a second jumper 8. Every 24 hours, one of the teeth of the toothing 40a is provided to be actuated by a second finger 3b of the mobile 3 calendar drive, so as to allow drive of the disc 2 of the days, and thus allow an update of the indication of the days.
  • the mobile 4 for days includes a second wheel 41 integral in rotation with the first wheel 40, which drives the disc for days 2 by means of an intermediate mobile 5 as shown in the figure 2 .
  • This intermediate mobile 5 comprises a pinion 50 provided with a toothing 50a intended to be meshed by the toothing 41a of the second wheel 41, as well as a wheel 51 provided with a toothing 51a provided for driving a toothing 2a of the disc for days 2.
  • the disc for days 2 is separated from the mobile for days 4 in order to establish a kinematic connection between these two elements.
  • the advantage of such a design is that the second day indicator is moved to the outer periphery of the first date indicator, while placing the second day indicator at the same level as that of the first date indicator.
  • the second indicator 20 of the days is arranged on the second disc 2 of the days which has the specificity of being actuated by a kinematic chain 4, 5 interposed between the mobile 3 calendar drive and the disc 2 of the days.
  • the modules of the teeth 41a, 50a, 51a, 2a are defined so as to minimize as much as possible the angular play between the mobile 4 of the days and the disc 2 of the days.
  • the modules m1 of the teeth 41a, 50a and m2 of the teeth 2a, 51a are less than 0.5, or even less than 0.3, or even less than 0.2. More particularly, the modules m1 and m2 can be between 0.07 and 0.2.
  • the number z2 of teeth of the toothing 2a is preferably between 30 teeth and 240 teeth, in particular between 80 teeth and 150 teeth.
  • the toothing 2a has a module m2 of 0.15 and includes 112 teeth.
  • the angular play between the mobile 4 and the disc 2 can also be minimized by means of a mobile 4 and / or a mobile 5 and / or a disc 2 in the form of a mobile game catching device such as that for example the subject of the patent application EP1555584A1 .
  • the teeth 40a, 41a, 51a, 2a may be wholly or partly fitted with elastic teeth with backlash.
  • the second toothing 2a of the disc 2 of the days is an internal toothing.
  • Such a solution makes it possible to simplify as best as possible the kinematic chain interposed between the driving mobile 3 and the disc 2, while minimizing the total diameter of the calendar mechanism.
  • Disc 2 of the days advantageously has a layered conformation on two distinct levels.
  • the day indicator 20 is arranged on the second face 21 passing through a first plane P1, while the toothing 2a has come from the material of a board 2b whose upper surface extends along a second plane P2, parallel to the first plan P1.
  • the distance between the first and second planes is equal to or substantially equal to the thickness of the first disc (measured parallel to the axis A).
  • the distance between the first and second planes is between 0.1 mm and 0.3 mm, or even between 0.15 mm and 0.25 mm.
  • the second disc has a section (along a plane passing through the axis A) in L or substantially in L.
  • the first disc of the dates 1 is preferably planar.
  • the first disc has a section (along a plane passing through the axis A) rectangular or substantially rectangular.
  • the first date disc 1 is configured to be arranged between the board 2b of the second day 2 disc and a calendar bridge 91, so that the first face 11 carrying the at least one date indicator 10 is placed on the same plane P1 than that of the second face 21 carrying the at least one indicator 20 for the days.
  • the figure 3 illustrates a sectional view of the calendar device 100 along a plane passing through the axis A.
  • the axial framing (along the axis A) of the first disc of the dates 1 is advantageously defined by the calendar bridge 91 and a circle 90 calendar, including a first span 90a of the calendar bridge.
  • the axial framing (along axis A) of the second disc of days 2 is, for its part, defined by calendar keys 92 arranged on the calendar circle 90, as well as by a second bearing 90b of the calendar circle 90 .
  • the axial framing of the date disc can thus be defined independently of the axial frath of the day disc, and vice versa.
  • any other element can be envisaged to participate in the definition of the respective axial clearance of the date and day discs.
  • the calendar bridge 91 can be replaced by calendar keys, or by the dial of the timepiece incorporating the calendar mechanism.
  • the calendar keys 92 can be replaced by a calendar bridge, or by the dial of the timepiece incorporating the calendar mechanism.
  • the second toothing 2a of the disc 2 of the days has a head diameter d2 strictly greater than the head diameter d1 of the toothing 1a of the disc 1 of the dates.
  • This mechanism 39 for rapid calendar correction comprises a mobile 30 for correction, arranged at least essentially within the perimeter defined by the diameter d1.
  • the correction mobile can in particular comprise a star 31 intersecting the plane P2, but which is designed to directly actuate the toothing 1a of the disc 1 without the risk of interfering with the toothing 2a of the disc 2.
  • the foot diameter of the first toothing 1a is preferably less than the head diameter d2 of the second toothing.
  • d2 is equal to or substantially equal to 1.2 ⁇ d1.
  • the correction mobile 30 also comprises a wheel 32 provided for actuating the toothing 2a of the disc 2 via the mobile 4 for days. More particularly, the wheel 32 can be provided for engaging with a mobile 33 meshing with the wheel 41 which is kinematically linked to the second disc 2.
  • the mobile 30 is movable in the plane of the calendar mechanism, that is to say along the plane P1 or along a plane parallel to the plane P1, by means known from the prior art, in particular using the means described in the request EP2701014A1 .
  • the calendar coach 3 mobile is an instant coach mobile as shown in the figure 5 .
  • Finger 3a no visible on the figure 5 , may be integral with a calendar cam 3c cooperating with an elastic rocker 3d, such as that disclosed in the request WO2013102600 , so that this finger can instantly drive, with an angular step, the first disc 1 of the date.
  • the finger 3b can also be integral with the calendar cam 3c so that this finger can instantly drive, with an angular step, the disc 2 of the days.
  • the energy consumption of the mobile 3 can be minimized by minimizing the respective inertia of the first and second discs 1, 2.
  • the disc 2 may in particular include blind openings 2c and / or through holes 2d in the plate 2b and / or under the face 21.
  • the at least one indicator 20 of the days comprises indications of the days conformed or presented in an arc of a circle.
  • the day indications are configured to appear within a window 62 or a window of a dial 6 of the timepiece, which also has an arc of geometry. Also preferably, this window 62 is arranged at "noon” or at "12 o'clock" on the dial.
  • the date indications are configured to appear within a window 61 or a window of the dial 6.
  • this window 61 is arranged at "3 o'clock" on the dial.
  • the directions of rotation of the first and second date and day discs are identical around the axis A in normal operation of the timepiece, that is to say during date changes at midnight, unlike those known from the prior art. This sense is also identical during the correction phases with the correction mechanism described above.
  • the fingers 3a and 3b of the mobile 3 are elastic so as to allow correction of the calendar at all times.
  • a horological calendar is thus proposed provided with at least a first date indicator arranged on the same plane P1 or substantially on the same plane P1 as that of at least a second day indicator. This optimizes the display quality perceived by the user.
  • the second day indicator is arranged on the outer periphery of the first date indicator, so as to provide a written indication of the day indication. This optimizes the readability of the information displayed.
