    The invention further relates to a watch comprising at least one such display mechanism.
    The invention relates to the field of watch display mechanisms, particularly for watches, and more particularly the calendar display mechanisms.
    BACKGROUND OF THE INVENTION [0004] The readability of the displays is a major concern in watchmaking, especially for calendar-type displays, which are difficult to produce in formats that are easily visible and decrypable by the user.
    The clock displays are rarely made by rolls because the indications in this form are greedy in thickness, because of the diameter of the roll, comprising for example up to 31 indications for the days of the month, or 52 indications for the weeks of year, and inconsistent with the particular geometry of a watch.
    And the possible use of characters of very small size requires the use of magnifiers in the thickness of the watch ice, which greatly affect the aesthetics of the watch, while remaining difficult to read.
    The shutter or vane displays, static type, for clocks and other clocks, can not be transposed to watches because generally using gravity. They are more fragile and can not withstand shocks.
    US 3 964 428 in the name of ARAI KIYOYUKI discloses a two-sided rotary shutter indicator, on the periphery of a rotary drum, with means for guiding the flaps held tangentially oriented. When rotating the drum a mechanism allows the flaps to turn around their own axis. SUMMARY OF THE INVENTION [0009] The invention proposes to develop a roller display, with readable watch indications despite the limited diameter of the rollers.
    For this purpose, the invention relates to a clock display mechanism comprising at least one roller pivoting about a roll axis, said roller comprising at least one flap pivoting about a flap axis parallel to said roll axis and separate from said roll axis, said at least one flap having at least a first face and at least a second face, said display mechanism including first drive means for pivoting said roll about said roll axis wherein said display mechanism has second drive means separate from said first drive means for rotating at least one said flap about said flap axis in at least one determined position of said flap axis relative to said flap axis. roller axis, characterized in that at least one said roller comprises at least one fixed display position and at least one movable display position by a said flap having a plurality of said faces.
    The invention also relates to a watch comprising at least one such display mechanism.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention is illustrated in the figures, in a nonlimiting manner, with rolls of the days of the week, the date (a roll of tens and a roll of units), and months. .
    Fig. 1 illustrates, for example, without limitation, a watch with rollers, with a character height greater than 2.20 mm, on a roll diameter 5.00 mm.
    Thus, the invention relates to a watchmaking display mechanism 100 comprising at least one roller 10, taking in the figures differentiated references: 11,12,13,14, pivoting about a roll axis D10 . This roll 10,11,12,13,14 comprises at least one flap 20 which is pivotally mounted about a flap axis D20 parallel to the roll axis D10 and distinct from the roll axis D10. This at least one flap 20 comprises at least a first face 201 and at least a second face 202, arranged so that the user can view only one of these faces at a given instant.
    The display mechanism 100 includes first drive means 31 for pivoting the roller 10, 11, 12, 13, 14 around the roller axis D10.
    This display mechanism 100 comprises second drive means 32, separate from the first drive means 31, for pivoting at least one such flap 20 around its flap axis D20, in at least one predetermined position. of the flap axis D20 with respect to the roller axis D10.
    More particularly, in this display mechanism 100, a constant rotation of the flaps 20 according to the rollers 10, 11, 12, 13, 14, is calculated so that at the display position visible by the user , the indication of the flap 20 is rotated 180 ° per revolution of roll 10, 11, 12, 13, 14.
    More particularly, the second drive means 32 are arranged to rotate a single flap 20 at a time, independently of the other flaps 20 that comprises a roller 10, 11, 12, 13, 14.
    In another variant, the second drive means 32 are arranged to synchronously rotate each flap 20 that comprises a roller 10, 11, 12, 13, 14. This saves the energy required for display mechanism.
    In the preferred embodiment, because less space consuming, where the second drive means 32 are arranged to rotate a single flap 20 at a time, more particularly, the second drive means 32 are arranged to make pivoting the single flap 20 at a single determined position of the flap axis D20 with respect to the roller axis D10.
    More particularly, the second drive means 32 comprise, at each flap 20, at least one flap drive gear 35 oriented on the flap axis D20. This flap drive gear 35 is more particularly arranged to cooperate with a control means, which comprises the display mechanism 100, to modify in sequence or continuously the position of the successive flaps 20 of the same roller 10, 11 , 12, 13, 14, or to modify on demand the position of a particular flap 20. It is thus possible to modify on demand the position of a specific component.
    [0023] In particular, an operator of the second drive means 32, or a control by a watch rod, or a pusher, a bolt, or the like, facilitates the updating of a calendar after an extended stoppage of time. a watch.
    More particularly, each flap 20 comprises, for its maintenance in the orientation position, a shutter cam 25, in particular a cam-core, comprising as many low points 26 as the shutter 20 comprises faces 201, 202. And the roller 10, 11, 12, 13, 14, preferably comprises at least one spring 15 which is arranged to exert a force on a jumper 17 disposed near each shutter cam for the indexing in position of this shutter cam 25, as visible in FIGS. 9 and 11.
    In a particular variant, as shown in FIG. 21, the pair formed by this jumper and this spring is advantageously replaced by at least one spring 15 of special shape, in particular a single spring as illustrated, combining the two functions of spring and jumper, and replacing all the jumpers 17 of the variant of FIGS. 9 and 11.
    In a variant of similar functionality, more particularly, each flap 20 comprises, for its holding in the orientation position, a flap cam 25 or a cam-heart having as many low points 26 that the flap 20 has faces. 201,202, and the roller 10, 11,12, 13, 14 comprises, for each flap cam 25 or heart-cam, at least one magnet 70 arranged to exert a force on the flap cam 25 or cam-core of magnetic material for indexing in position of the shutter cam 25 or cam-core, as visible in FIG. . 17
    More particularly, the first drive means 31 comprise, as shown in FIGS. 3 and 4, a control wheel 3120, 3130 of which some teeth are omitted, and which meshes with a roller drive gear 312, 313, either directly or via a reduction torque 3131, to obtain the desired reduction. This allows in particular the display of the date.
    More particularly, according to the invention, at least one roll 10,11,12,13,14, comprises at least one fixed display position and at least one mobile display position by a shutter 20 comprising a plurality of faces 201,202, as visible in FIG. 16. This allows a roller display with all kinds of indications in a small volume.
    More particularly, the first drive means 31 comprise an input gear train 61 which drives a main wheel 60, one revolution of which corresponds to the display time period of the roller 10, 11, 12, 13, 14, and which carries a main cam 50 carrying peripheral sectors 51 separated by recesses 52, the peripheral sectors 51 being of unequal amplitude, the shortest corresponding to the fixed display positions, and the longest corresponding to the mobile display positions. The main cam 50 cooperates with a secondary eccentric Maltese cross cam 40 and arranged to pivot during the passage of a recess 52. The secondary cam 40 carries a secondary wheel 42 meshing with a roller drive wheel 62. The wheel main 60 still carries a flap drive main wheel 63, which in turn meshes with a flap gear 64 which is arranged to drive a flap drive gear 35 centered on the flap axis D20 or itself constituting even such a flap drive sprocket 35.
    The invention also relates to a watch 1000 comprising at least one such display mechanism 100.
    The figures illustrate particular embodiments of the invention.
    FIG. 2 illustrates a date display on a roll. Since 31 days can not be displayed on the circumference of a roll of 5mm in diameter, or similar, the units and tens are spread over two rolls: four digits on a roll of tens 12, ten digits on a roll of units 13 .
    The two rollers are driven by two control wheels 3120 and 3130, 31 teeth each, where teeth are removed, corresponding to the days when no rotation of the respective roller is necessary.
    FIG. 3 shows the drive train of the tens roll 12: the first drive means 31 comprise a first control wheel 3120, which has only four teeth present on the 31 theoretical teeth, to drive the four teeth of a star to four teeth 312 dozens roller drive 12. A jumper not shown in the drawing is necessary to maintain the position of the four-tooth star 312, and finish the drive function.
    FIG. 4 shows the drive train of the roll of the units 13: the first drive means 31 comprise a second control wheel 3130, which comprises only a part of the 31 theoretical teeth, depending on the type of display produced, to drive the ten teeth of a pinion of the drive units 313 of the roll of the units 13. The second control wheel 3130 may thus have either thirty teeth or, as here, twenty-nine teeth, the two missing teeth allowing to cancel the rotation of the units during the passage from 31 to 01. A jumper not shown in the drawing is necessary to maintain the gear position of the units 313 to ten teeth, and to maintain the display position.
    These training principles are similar to those well known date displays with large windows.
    Figs. 5 and 6 illustrate the display of units on a roll of units 13. The ten units distributed around the circumference of a 5mm diameter roll do not allow a large enough character size. Also the roll of the units 13, according to the invention, comprises several flaps 20A, 20B, 20C, 20D, 20E, each carrying on its at least two opposite faces 201,202, at least two numbers of the units. In this example, the roll of the units 13 is thus divided, and five flaps 20 with two faces carry the ten units. These flaps 20 have alternately their two faces 201 and 202 to the user, and allow to double the height of the characters of the units.
    Figs. 7 to 11 illustrate the rotation and the holding in place of the flaps 20 during the rotation of the carrier roller 10, and their own rotation.
    The flaps 20 may be driven in continuous rotation relative to the rotation of the roller 10, with a ratio of one half. This solution is simple but requires space on the entire circumference of the roll 10, which is not always possible.
    To limit the size of the system, it is advantageous to use the solution described below, which manages a rotation of a flap 20 at a single point of the circumference of the roll 10. Each flap 20 is then maintained in position by a jumper 17, which collaborates with a shutter cam 25, in particular of the cam-core type, with two positions, mounted on the axis of the flap concerned, whose bottom point 26 cooperates with a salient of the jumper 17. spring 15, in particular as in FIG. 7 a spring multi-arm, applies a force on the jumper 17 which maintains the position of the flap 20. A pinion 35 is also mounted on the axis of the flap 20.
    This pinion 35 can be driven by a gear that includes the second drive means 32, not shown in the figures. In the particular variant of FIG. 7, the second drive means 32 comprise a stationary toothing segment located at a point on the periphery of the roller 10. During the rotation of the roller 10, a flap pinion 35 comes into cooperative contact with this segment; which generates a rotation of 180 ° of the flap 20 concerned.
    Figs. 12 to 14 similarly illustrate the rotation of a roll of months having six flaps 20. Naturally, to make twelve indications on the circumference, it is also possible to use four flaps with three faces, or even three flaps with four faces.
    FIG. 15 illustrates the rotation of a roll of the five-part units. As explained above, the rotation of a roll of the units can be done with a wheel 31 which lacks one or two teeth for the passage on a pinion of ten teeth. For a rotation of 1/5 turn per day, for a roll with five flaps, the ten-tooth gear should be reduced to five teeth, geometrically this reduction is not possible with the function. It is therefore necessary to add a gear reduction with a reduction torque: 3132, 3133, corresponding to the desired reduction. In this example, the various wheels of the gear train perform: - 3130 of 31 teeth: 1 revolution per month - 3162 of 10 teeth: 1 revolution per 10 days - 31313 of 20 teeth: 1 revolution per 10 days - 313 of 10 teeth: 1 turn per 5 days [0044] In a particular embodiment of the Maltese cross, the first drive means 31 comprise an input gear 61 which drives a main wheel 60, one revolution of which corresponds to the time period of display of the drive. roller 10,11,12,13,14, and which carries a main cam 50 carrying peripheral sectors of unequal geometry, concentric sectors 51 corresponding to the fixed display positions, and sectors with recesses 52 and provided with pins. 5X drive corresponding to the moving positions of the display roller 10,11,12,13,14. This main cam 50 cooperates with a secondary eccentric Maltese cross cam 40, pivoting about a fixed point, and arranged to pivot during the passage of a recess 52 and a pin 5X. This secondary cam 40 carries a secondary wheel 42 meshing with a roller drive wheel 62, and the main wheel 60 still carries a shutter drive main wheel 63, which meshes itself with a shutter pinion 64 arranged to controlling a shutter drive gear 35 oriented on the shutter axis D20 or itself constituting a shutter drive gear 35.
    More particularly, lafig. 16 illustrates a particular variant that embodiment Maltese cross, for the control of rotation of a roller with seven indications, corresponding to the days of the week. In this case days of the week, the number of days being a prime number, it is not possible to distribute it on flaps as simply as before. If the roll does not display the seven days on the circumference, the solutions are limited: - roll with six fixed positions and a flap with two faces; - roller with five fixed positions and two flaps with two faces; - roll with four fixed positions and three flaps with two faces; - roller with a fixed position and two flaps with three faces; FIG. 16 describes the first variant of a roll with six fixed positions and a two-sided flap. The adaptation to the other variants can be carried out in a similar way. The first drive means 31 comprise an input gear train 61, which drives a main wheel 60, one revolution of which corresponds to the display time period of the roll 10, in the application to the display of the days of the week, this main wheel 60 is driven 1/7 turn per day.
    More generally, for a display of N periods, the main wheel 60 is driven 1 / N of turn per day.
    The main wheel 60 carries a main cam 50, which is separated into N different peripheral sectors. These peripheral sectors are of unequal geometry: concentric sectors 51 correspond to fixed display positions, and sectors with recesses 52 and provided with drive pins 5X correspond to the mobile positions of the display roller. In addition, the angular amplitude of the concentric sectors 51 may be variable, as will be seen later.
    This main cam 50 cooperates with a secondary cam 40 in Maltese cross, by the pins and notches mentioned above. This secondary cam 40 is eccentric, pivots about a fixed point, and is arranged to pivot during the passage of a recess 52 and a pin 5X.
    This secondary cam 40 carries a secondary wheel 42 which meshes with a roller drive wheel 62, itself secured to the display roller 10 concerned.
    The secondary cam 40 Maltese cross thus causes, six days out of seven, this wheel drive wheel 62 of 1/6 of a turn, which corresponds to six fixed positions of the roller.
    On the seventh day, the range 41 of the secondary cam 40 in Maltese cross rest on the longest 510 concentric sectors 51, and the secondary cam 40 Maltese Cross can not rotate. The roller drive wheel 62 is not driven, and the roller then remains stationary.
    The main wheel 60 still carries a main flap drive wheel 63, which meshes itself with a flap gear 64 arranged to control a flap drive gear 35 centered on the flap axis D20, or itself constituting a shutter drive gear 35.
    This main impeller drive wheel 63 performs, as the main wheel 60.1 / 7 turn per day.
    The flap pinion 64 carries the flap 20 on both sides, and meshes with a ratio of 3.5 with the main flap drive wheel 63.
    Thus, when the roller drive wheel 62 is stationary, and the main wheel 60 is 1/7 turn, the shutter gear 64 is 1/2 turn, with side change of the flap 20.
    When the roller drive wheel 62 is released and 1/6 turn and the main wheel 60 is 1/7 turn, the shutter pinion is 1/12 turn, so in six days will resume his starting place.
    Figs. 17 and 18 illustrate an advantageous variant of the invention, wherein the jumpers and the spring ensuring the position of the flaps are replaced by magnets 70, which exert a force, including attraction, on the cams of magnetic material.
    In another particular embodiment with partial teeth, instead of the Maltese cross systems described above, the first drive means 31 comprise an input gear train 61 which drives a main wheel 60 of which a revolution corresponds to the display time period of the roll 10, 11, 12, 13, 14, and which carries a main cam 50 carrying peripheral sectors of unequal geometry: concentric sectors 51 corresponding to the fixed display positions, and sectors having drive means 53 adjacent to recesses 52. The main cam 50 cooperates with an eccentric star 71, pivoting about a fixed point, and arranged to pivot when passing such a drive means. 53, and to remain in its angular position when two teeth 72 that it comprises are supported on a concentric sector 51. This star 71 carries a secondary wheel 70, which meshes with a a roller drive wheel 62 itself secured to the roller 10, 11, 12, 13, 14, the main wheel 60 carries, as before, a shutter drive main wheel 63, which meshes itself with a shutter pinion arranged to control a shutter drive gear 35 oriented on the shutter axis D20 or itself constituting a shutter drive gear 35.
    More particularly, FIGS. 19 and 20 illustrate a variant of this embodiment, which comprises partial teeth. This variant is illustrated for a particular non-limiting case of a version with five fixed positions, comprising two movable flaps 20B and 20E with two faces, and without Maltese crosses.
    A drive gear of the input train 61 not shown performs 1 turn per day, and drives a main wheel 60, which is 1 / N, here 1/7 turn per day.
    The main wheel 60 carries a main cam 50, which is separated into seven different peripheral sectors, the peripheral sectors with or without drive means (here constituted by teeth 53), the concentric sectors 51 corresponding to the fixed positions. display of the roller 20, and sectors with drive means 53 corresponding to the movable positions of the display roller.
    This main cam 50 cooperates with a star 71 of 4 teeth, maintained by a jumper not shown. This star of four is eccentric, pivots about a fixed point, it is arranged to pivot during the passage of a drive means, in particular a tooth in the illustrated embodiment, not limiting.
    The drive means 53 comprising here teeth, and preferably combined with the recesses 52, are arranged to mesh with teeth 72 of the star of four 71. By cons, when two teeth 72 successive of the star of four 71 are simultaneously supported on a concentric sector 51, the star of four 71 can not rotate.
    The star of four 71, rotated on the plate, is thus arranged to perform 1/4 turn per day, except two days a week. In the illustrated example, when this star 71 has rotated from Monday to Tuesday, it remains in its position on Tuesday and Wednesday, before changing positions between Wednesday and Thursday. In the same way, when star 71 has rotated from Friday to Saturday, it stays in its position on Saturday and Sunday, before changing positions between Sunday and Monday. Strand 20B will show a first position on Tuesday, turning 180 ° from Tuesday to Wednesday, to post a second position on Wednesday. In the same way, the 20E component will show a first position on Saturday, pivoting 180 ° from Saturday to Sunday, to post a second position on Sunday. On other days, the user will see fixed displays around the 20: 20A roll on Monday, 20C on Thursday, 20D on Friday.
    This star of four 71 carries a secondary wheel 70, which meshes with a roller drive wheel 62, itself secured to the display roller 10.
    The star of four teeth 71 causes in fact, five days out of seven, this wheel drive wheel 62 of 1/5 of a turn, which corresponds to the five fixed positions of the roller.
    The two additional days, the star of four 71 remains supported on the concentric sectors 51, and can not rotate. The roller drive wheel 62 is not driven, and the roller 10 then remains stationary.
    The main wheel 60 still carries a main flap drive wheel 63, which meshes itself with a shutter pinion arranged to control a shutter drive pinion geared to the shutter axis D20, or itself constituting a shutter drive sprocket 35.
    This main impeller drive wheel 63 performs, like the main wheel, 1/7 turn per day.
    The shutter gears are flaps 20B and 20E two-sided, and meshing with a ratio of 3.5 with the main impeller drive wheel 63.
    Thus, when the roller drive wheel 62 is stationary, and the main wheel 60 is 1/7 turn, the shutter gear is 1/2 turn, with side change of the flap 20 concerned.
    When the roller drive wheel 62 is released and 1/5 turn and the main wheel 60 is 1/7 turn, the shutter gear is 1/10 turn, so in 5 days will resume his starting place.
    Figs. 22 to 26 represent, schematically, a variant for a leap year display 400. This display leap years 400 can be done by one or more needles, including and not limited to the example of the figures with a triple needle 401 to 120 °, in the extension of the axis 402 of the roll of months, facing a leap-supplementary display 403, in particular conventionally comprising marks such as 1,2,3, L, or B, or the like. A star 404, held by a jumper 405, drives this triple needle 401, and is itself driven by an eccentric lever 406 integral with a flap 407. In the illustrated example, the rotation of the star 404 is made by an eccentric lever 406 secured to the shutter 407 of the months of March / September. When this flap 407 pivots through the toothed sector 408, the latter pushes the star 404 one notch, as can be seen in fig. 24 and 25. The roller makes a turn in six months, in July the lever does not trigger the rotation of the star.

    FIG. 27 illustrates another variant of holding flaps 407 without jumper, and driven by a partial toothing, with a guide by an outer circumference 420 in contact with the flap 407 itself. In particular, as visible in FIG. 27, the flap 407 is guided in position by two teeth 410, 411, of its drive pinion 409. This can have one or more teeth removed, at a recess 412, to facilitate the function. The support is advantageously on an outer or inner partial guide circumference, by two teeth delimiting a circumference of rotation intersecting the guiding circumference. This crossing limits the rotation of the rollers on their axes. The guiding circumference is interrupted on a portion 421 allowing rotation. This rotation is controlled by a gear segment 408 provided for this purpose. The latter can, as in the figure, be part of the guiding circumference 420. In the same way, in a variant of flap without jumper, the shutter can be guided directly by an outer circumference in contact with the flap. -even. In this way, the guide circumference is interrupted to let the flap. The drive gear can then be found in the configuration of the variant of Figs. 7 to 11, or in that of FIGS. 17 and 18. [0077] The various variants of the invention make it possible to produce roller displays of all kinds of indications in the reduced volume of a watch of normal size, with in particular a total thickness of the order of 10. mm outside the ice, or ice and bottom.
