    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention relates to an adjustment mechanism 10 for a clock display mechanism 20. This display mechanism 20 comprises at least a first input wheel 2, which is arranged to drive directly or indirectly a first control wheel 3, to control the position of a first display 30 that includes this display mechanism 20 .
    According to the invention, the adjustment mechanism 10 comprises a differential gear mechanism 50, which comprises a mobile coach 4 retained by a jumper display 40. This mobile coach 4 is arranged to be pivotally driven by the first input wheel 2, and is arranged to drive at least one satellite 5 meshing with the first control wheel 3.
    This satellite 5 is pivotally mounted and offset relative to a planet carrier 6. This planet carrier 6 forms a friction spring, and is frictionally mounted, or else by protuberances 61, which it comprises, in a cavity 62 of a frame 15 of the mechanism, of adjustment 10, or else by internal friction on a bearing surface of said frame 15. The differential gear mechanism 50 is arranged to multiply by a given particular factor, in particular an integer factor, the rotation between one of the inputs and the differential output when the other input is fixed. This factor is equal to two for the nonlimiting embodiment illustrated by the figures, for the application with the roller of the units of a roller display; this ratio can be 1.0 or 0.5 if it is applied for example to the roll of tens of the same display.
    And this planet carrier 6 includes handling means 7, which are arranged to allow a watchmaker to release friction to modify the angular position of the satellite 5, a position which influences and determines the position of the first control wheel 3 for its correct indexing with respect to at least one other display 80 that includes the display mechanism 20. In the nonlimiting embodiment illustrated by the figures, these manipulation means 7 comprise two arms that can be manipulated by tweezers or the like; in another embodiment, they may include holes or pins, arranged to cooperate with a tool of complementary shape, such as circlip pliers or the like. These handling means 7 can also be used to modify the angular position of the satellite 5 without influencing the friction, this influence not being necessary for the function but providing comfort in use.
    The invention also relates to a display mechanism 20 comprising at least one such adjustment mechanism
    10. More particularly, the display mechanism 20 is an instantaneous or semi-instantaneous display mechanism, and comprises at least one driving mobile 9 comprising at least one finger 90 arranged to directly or indirectly drive the first input wheel 2 The illustrated embodiment relates to a date display mechanism. Such a display mechanism, or even a moon phase, or time zone, or other display, conventionally comprises at least one large wheel with a large number of small teeth: 31.59, 24 teeth, and the interface with a control finger or even with a jumper is generally imperfect. Thus, in particular, the first input wheel 2 is a large wheel comprising at least 24 teeth.
    To improve drive safety, during the usual drive of such a wheel by a finger, in particular in a tangential passage, and to prevent the finger also driving the previous tooth, or not causing any tooth , and to ensure the safety of maintaining in the locking position of such a large wheel by a jumper, and thus avoid loss of state during an impact or an acceleration of the carried, it is advantageous to perform a drive and indirect support of the big wheel concerned by a return.
    To this end, in particular, the display mechanism 20 comprises, between each driving mobile 9 and the first input wheel 2, at least one reference 91 having a number of teeth less than or equal to half the number of teeth of the first input wheel 2. Each finger 90 is arranged to cooperate with the reference 91 or with a star 92 integral in pivoting with the reference 91. And the display mechanism 20 comprises at least one input jumper 93, for a position lock engaged only with the reference 91 or with such a star 92, and a correction jumper 94 also engaged only with the reference 91 or with such a star 92, for the modification of the position.
    More particularly, at least one reference 91 is integral in pivoting with a star 92.
    More particularly, the display mechanism 20 includes a first driving mobile 9 which is a driving mobile, and a second driving mobile 9 which is a corrective mobile.
    More particularly, this at least one reference 91 is arranged to shift with a single tooth, during each jump in position of the reference 91, the first input wheel 2, or a second input wheel 22, or a front wheel 21, synchronous in pivoting with the first input wheel 2.
    More particularly, at least one reference 91 has a pivot axis orthogonal to that of the first input wheel 2 or of a second input wheel 22 synchronous in pivoting with the first input wheel 2.
    More particularly, the display mechanism 20 comprises a second input wheel 22, or a front wheel 21, synchronous in pivoting with the first input wheel 2, and with which second input wheel 22 or which front wheel 21 as in the case of the figures, at least one reference 91 cooperates.
    More particularly, the display mechanism 20 includes a single reference 91 arranged to cooperate with each mobile coach 9.
    The nonlimiting example illustrated by the figures relates to a first input wheel 2 with 31 teeth, one removed, synchronous in pivoting with a second input wheel 22 synchronous in pivoting with the first input wheel 2 and which is a truncated 31-tooth wheel of which only 4 teeth remain in positions 10, 20, 30 and 31, and is also synchronous in pivoting with a front 31-tooth wheel 21. This front wheel 21 allows a change of axis of rotation , which is necessary for the roller display mechanism illustrated in the figures, the axes of the rollers being parallel to the plane of the plate, and perpendicular to the axes of the moving parts of the movement. The reference 91 has 12 teeth, and cooperates with a twenty-four hour finger 90, conventionally mounted elastically on the driving mobile 9. The reference 91 is here coaxial and synchronous with a star of twelve 92. The date finger, driven by a clockwork movement not shown, works once a day, at midnight, with the star of twelve 92 to make a step of 1/12. The additional return 91 drives the front wheel 21 of 31 to make a jump of 1/31, according to a gear ratio 12/31. As the star of twelve 92 has here only 12 teeth, the drive function has greatly increased safety compared to a conventional direct drive on a wheel of 31 teeth, and the locking by jumper is improved in the same way . The reference 91 can be unique with the star 92, if a type of NIHS type of teeth is used, with pointed teeth allowing both finger training and positioning by jumper.
    In a particular application of the invention, illustrated by the figures, the display mechanism 20 is a roller display mechanism, the first display 30 of which is a first roller, and at least one other display 80 is a second roller, in particular but not limitatively coaxial with the first roller.
    Applications CH 00 849/16, EP16177 872, and EP 17175 547 from the same applicant describe particular arrangements of such a roller display mechanism, and their details are not reproduced herein. In particular, the date is displayed on two rollers, a single roller for the tens, and a roller with five pivoting flaps with two sides each for the units, which allows great readability of all the figures displayed. The display of the units is done on two rolls of rollers, in comparison with the display of the disc of the units of CH 310 559 which makes only one turn. The solution consisting in entraining a star of five is not geometrically optimal, in particular for the passage of the at least one missing tooth which manages the passage 31-01. An advantageous solution cited in applications CH 00 849/16, EP 16 177 872, and EP 17 175 547 is to multiply by a whole factor, here a factor two, the rotation of a star with a higher number of teeth, here a star of ten constituting the driving mobile 4, thanks to a mobile multiplier interposed between this star (of ten) and the roller.
    The multiplier cog, in particular by two, requires indexing so that the unit figures are displayed opposite the tens figures. As the cog is multiplier, the greater precision of this indexing is essential. It is, again, to simplify assembly, any construction with precise angular indexing of cogs being a difficulty for the watchmaker in charge of assembly, or adjustment in after-sales service.
    More particularly, the second roller, when it is coaxial, is arranged to be driven directly or indirectly by the first input wheel 2 or by a second synchronous input wheel 22 in pivoting with the first input wheel 2.
    More particularly, the second coaxial roller is arranged to be driven directly by a second input wheel 22 synchronous in pivoting with the first input wheel 2 and having an incomplete toothing.
    More particularly, the first roller comprises at least one flap 12 with two faces, with two display symbols on either side, pivotally secured to a pinion 13 which is arranged to pivot during its engagement with a toothed sector 14 which comprises a frame 15 of the display mechanism 20.
    More particularly, the display mechanism 20 is a date display mechanism, and the first roller is a display roller for the units indirectly driven by a first input wheel 2 which is a wheel of 31 teeth with one tooth removed (30 remaining teeth), or with two successive teeth removed (29 remaining teeth). The second roller is then a tens roller, driven directly by a second synchronous input wheel 22 in pivoting with the first input wheel 2 and which is a truncated 31-tooth wheel of which only 4 teeth remain in positions 10, 20, 30 and 31.
    The differential gear mechanism 50 is shown diagrammatically in FIG. 6:
    A: indexing and multiplication differential (here by a factor of two);
    B: unit training, star of ten, 1/10 turn per day;
    C: display of units;
    D: indexing of units, on friction.
    This differential train directly allows the multiplication by two between the first input and the output, when the second input is fixed.
    A rotation on the second input makes it possible to rotate the roll of the units independently of the star of ten, and to align the displays of units with that of the tens.
    This rotation is ensured by friction or by a locking, so that it can only intervene when adjusting by the watchmaker, in the particular embodiment where the gripping means 7 of the planet carrier 6 friction are inside the watch case.
    The differential train can advantageously be placed concentrically with the roller of the units, but this embodiment is in no way limiting.
    [0038] FIG. 2 shows the kinematic chain. The star 92 integral with the reference 91 drives the front wheel 21, and therefore the first input wheel 2, which is arranged to drive the driving mobile 4, at the level of a star of ten 42. This driving mobile 4 has a plate 41, here of twenty-five teeth, integral with this star of ten 42, and which meshes with the pinion 52, here at ten teeth, of a shaft 5 satellite 51, this satellite 5 pivoting relative to the holder satellite 6. Satellite 5 has a plate 53, here 16 teeth, which meshes with the first control wheel 3, which is here the pinion of the first roller 30 and here has twenty teeth. The second input wheel 22 is arranged to mesh with a pinion 81 which comprises the shaft 82 of the second roller 80.
    When the axis of the satellite 5 is immobilized in position by friction (normal operation at the date jump), the rotation NR of the first roller 30, is, depending on the rotation NE of the moving coach 4 (star of ten ), equal, in this particular and nonlimiting example, to: NR = NE * 25/10 * 16/20 = 2 * 0.1 = 0.2.
    More particularly, the first roller has five pivoting flaps 12 carrying on their ten faces the numbers from zero to nine. And, thus, the rotation of 1/5 turn per day is well respected.
    When the mobile coach4 (star of ten) is immobilized by its jumper40, that is to say in normal operation between midnight and 11:30 p.m., one of the elements of the differential calculation goes to zero, and the rotation NR calculates according to the manipulation of friction by the watchmaker NF (= 38 °):
    NR = NF * 20 * 10 / (20 * 10 - 16 * 25) = - 38 °.
    The 38 ° rotation (+/- 19 °) is well respected, and is correct and sufficient to allow indexing whatever the assembly: a tooth of the first control wheel 3 corresponding to 360720 = 18 ° .
    Friction is released by manipulating the gripping means 7, which are radial elements in the figures.
    More particularly, the display mechanism 20 also includes a roller for indicating the day of the week and comprising one or three pivoting flaps 12.
    More particularly, the display mechanism 20 comprises a roller for indicating the month and comprising six pivoting flaps 12.
    More particularly, the display mechanism 20 includes a roller for indicating the leap year.
    More particularly, the display mechanism 20 comprises a roller for indicating the moon phase, arranged to be driven by a wheel of 59 teeth.
    More particularly, the display mechanism 20 comprises a roller for the day / night indication, arranged to pivot twice a day.
    In summary, the invention, as illustrated, makes it possible to rotate a roller relative to the star of ten, which allows perfect alignment of the figures or symbols appearing on the different rollers, each with respect to the other. In its application to a traditional flat display, the friction specific to the invention makes it possible to greatly facilitate adjustments in calendar watches, for example in the case of an annual calendar.
    The invention is described here in a particular application where the gripping means 7 are accessible to the watchmaker alone, therefore preferably inside the watch case, but it is understood that these gripping means can also be deported outside the watch case for maneuvering by the user, subject to accompanying them with the essential sealing means. An application to a static timepiece, such as a pendulum, does not require very sophisticated sealing means, and is easy to carry out with a differential and friction adjustment mechanism according to the invention.
    This friction mount of the planet carrier 5 is advantageous, because it makes it possible to dispense with the usual prior adjustments, and, in the particular case illustrated with a roller display, it avoids having to index the roller pinion 3 on roller 30, the wheel of the reduction mobile on its pinion, and the wheel of the star of ten on the star. These three mobiles can therefore be assembled without any particular indexing, which represents a significant saving in time and know-how. The invention avoids having to index the mobile during assembly of the rollers, the components are approximately assembled, and the adjustment is made after assembly.
    The invention is particularly suitable for a perpetual calendar.
    The invention also relates to a watch 100 comprising at least one such display mechanism 20.
