Description

Technical Field

[0001] The invention relates to a roller jumping type timepiece display mechanism.

[0002] The invention also relates to a timepiece, in particular a watch, comprising at least one movement arranged to drive a cam included in such a roller jumping timepiece display mechanism.

[0003] The present invention relates to the field of timepiece display mechanisms. Background Art

[0004] It is often difficult to combine different displays on a timepiece, especially when the timepiece is of small dimensions like a watch.

[0005] And it is important to easily distinguish between the primary display and the secondary display without any risk of confusion.

[0006] One solution is to use a conventional display device (such as a pointer or a disk) for the first display and a roller display device as the second display. However, a roller display for a watch requires a considerable volume and is difficult to install in a watch. In addition, in order to avoid confusion in interpretation when the time or date changes, a momentary jump display is preferably adopted, which is more complicated. These limitations are further amplified when the second display involves values ​​with units different from those of the first display, which requires a conversion mechanism that further complicates the structure of the watch. Summary of the invention

[0007] The invention proposes developing a scroll wheel display for an instantaneous watch that provides the best display guarantees and that has reasonable dimensions that match the volume of the watch.

[0008] The invention is described for the specific case of a watch for a space mission to Mars, wherein the primary display relates to the Earth timetable and the secondary scroll display relates to the Mars timetable.

[0009] To this end, the present invention relates to a roller jumping timepiece display mechanism according to claim 1 .

[0010] The invention also relates to a timepiece, in particular a watch, comprising at least one movement arranged to drive a cam included in such a roller jumping timepiece display mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] - Figure 5 Schematically and in perspective is shown the hour tens roller, whose axle comprises the driving square, and which laterally carries the three planet carrier bolts or pivots for the release mechanism;

[0017] - Figure 6 shows the encoding of the minute display, in Figure 3 and Figure 4 A specific non-limiting variation of the mechanism illustrated by the accompanying drawings is constructed based on the coding;

[0018] - Figure 7 The coding for the hour display is shown in Figure 3 and Figure 5 A specific non-limiting variation of the mechanism illustrated by the accompanying drawings is constructed according to this coding on the basis of the illustrated roller;

[0019] - Figure 8Schematically and in perspective, a first display device group is shown in the right part, which is the minute display device group and comprises from right to left Figure 3 The minute wheel and Figure 4 and a second display device group is shown in the left part, which is an hour display device group and includes from right to left similar to Figure 3 The hour unit wheel and Figure 5 The four rollers are coaxial and each of them is connected to a star held in a rest position by a jumper; the hour tens roller carries laterally a clover similar to the one carried by the minute tens roller, which is integral with the self-closing wheel of the release mechanism and in whose teeth it can block a wheel mounted as an idler wheel. Figure 5 a planet wheel on a planet wheel carrier bolt or pivot to rotate the hour tens roller by engaging the wheel, and disengagement of the planet wheel causes release;

[0020] - Fig. 9 The control of the minute trigger lever is shown schematically and in side view, for controlling the inner roller of the combined minute units roller; the lever pivots in the lower left part of the drawing and is subject to the action of a return spring which tends to press the driving finger included in the lever against the star included in the inner roller and which in turn is subject to the return torque of the positioning lever to keep it in the rest position; the lever carries, between its pivot and its distal driving finger, on the one hand, a ten-minute contact finger arranged to cooperate bearingly with a ten-minute cam, which is a cam with straight edges of the slit type; and, on the other hand, a minute contact arbour arranged to rest on the substantially helical track of the minute cam; the cam comprises means to prevent any backward movement at the moment of the jump when the contact arbour leaves the high point of the cam (which is its position in the present drawing);

[0021] - Fig.10 Shown by Fig. 9 The switching of the minute position of the mechanism is when the ten-minute contact finger is not stopped by the release of the ten-minute cam and just after the jump of the contact spindle, when the descent of the rod just drives the star of the roller that has rotated one position;

[0022] - Figures 11 to 14 is relative to Fig. 9 and Fig.10 A side view from the opposite side shows details of the sequence of cooperation between a drive finger pivotally mounted and comprising a resilient blade movable between two abutments and a star of the roller;

[0023] - Fig.11 is similar to Fig. 9The rest position of the rod before it is lowered; the elastic blade is supported on a first front abutment located on the side of the star;

[0024] - Fig.12 It is shown that during the descent of the rod, the finger comes into contact with the star, the finger blade leaves the first abutment and the finger starts to pivot in the direction of the arrow;

[0025] - Fig.13 The contact between the blade of the finger and the second abutment is shown, as well as the driving of the pivoting star, with the rod accompanying the star during about two thirds of its step before its abutment, which ensures the passage of the top of the positioning rod;

[0026] - Fig.14 The rise of the rod is shown, during which the finger is free, until the blade of the finger bears against the first limiting abutment; the blade being weaker than the star-positioning rod, the blade bends to pass over the top of the star, so that the star cannot be driven again by the finger;

[0027] - Fig.15 and 16 The minute cam is illustrated schematically and in perspective from above and below: the minute cam is in the form of two parts, one of which comprises a substantially helical track wide enough for two contact spindles comprising two adjacent rods to be traversed simultaneously, the upper part being rotationally movable relative to the lower part, wherein the angular mobility is limited by the cooperation of a pin integral with the cam part, wherein an oval pod-shaped slot limits the angular freedom: thus, during the descent, when the contact spindle of the rod passes the top of the cam, there is no recoil effect, and the descent of the rod can be used to drive the roller star in a momentary jump;

[0028] - Fig.17 This minute trigger lever for controlling the inner roller is shown schematically and in perspective, juxtaposed with the minute trigger lever for controlling the outer roller, whose contact arbors therefore travel together along this same spiral track of the cam and whose ten-minute contact fingers are both arranged to cooperate with the same ten-minute cam, which allows or prohibits the descent of the lever; this figure also shows the return springs of these two levers; the units roller, on the left in the figure, carries a claw intended to cooperate with a groove of a Maltese cross contained in the ten-minute drive mechanism;

[0029] - Fig.18 shows schematically and in perspective a detail of the contact arbors of two adjacent levers travelling together through the spiral track of this same minute cam;

[0030] - Fig.19 Similar to Fig.17and shows the same assembly in the position it occupied a few seconds before the jump, in the display position of the units of the minutes “4”, in which the outer roller shows its aperture and the inner roller shows the number 4; the mechanism is ready to switch to the display position “5”, in which the outer roller shows the number 5, while the inner roller switches back to its position showing the number 0 and is thus ready in anticipation of the switch to the next ten minutes, in which the inner roller will show its number 0 in the aperture of the outer roller; neither lever being here stopped by the ten-minute cam;

[0031] - Fig. 20 Similar to Fig.19 , and shows the same assembly after a jump, in the intermediate display configuration, in which neither of the two levers is stopped by the ten-minute cam, which opposes the descent of one of the levers passing therethrough, to cause the inner or outer roller to rotate or not to rotate; whereby each lever has driven its corresponding roller, and at the same time the outer and inner rollers have rotated one position;

[0032] - Fig.21 Similar to Fig. 20 , and shows the same assembly after the next jump for switching the display from display position “5” to display position “6”, in which only the outer roller rotates, while the inner roller remains in its position displaying the number “0”; in fact the inner roller does not rotate, and remains in its display position, since the lever corresponding to the display of the inner roller is stopped by the ten-minute cam, the contact finger of this lever abutting against the slot of the ten-minute cam, and therefore the inner roller does not rotate, and only the lever associated with the outer roller descends and pivots the outer roller;

[0033] - Fig. 22 and 23 Schematically and in perspective from two opposite sides, a ten-minute drive mechanism is shown, which surrounds a display device group including a combined minute units roller and a single minute tens roller; the mechanism is a mobile device having an axis parallel to the common axis of the axes of the various rollers and comprising a Maltese cross on the side of the combined minute units roller, the groove of which is arranged to engage with a claw ( Fig.17 and comprises a lug star on the side of the minute tens roller and rotating integrally with the Maltese cross; the lugs of the lug star are arranged to Figure 4 The groove of the ten-minute clover-shaped piece fits;

[0034] - Fig.24 Similar to Fig. 20 , and is composed of Fig. 22 and Fig.23The ten-minute drive mechanism is completed and the same assembly is shown in the position it occupied a few seconds before the jump, in the display position of the units of the minute "9", where the outer roller shows the number 9 and the inner roller shows the number 0; the mechanism is ready to switch to the display position "10", where the tens roller will switch to the position "1" until it is then in the display position "0"; and at the roller combined with the units, the outer roller will show its aperture through which the inner roller will continue to display "0" without rotating; the groove of the Maltese cross of the units of the minute cooperates with the claw of the units roller;

[0035] - Fig.25 Similar to Fig.24 and shows the same assembly after a jump, in the intermediate display configuration, in which neither of the two levers is stopped by the ten-minute cam; the outer roller which combines the minute units roller pivots, and its claw causes the Maltese cross to rotate, which at the other end causes the ten-minute clover and, therefore, the ten-minute roller to rotate;

[0036] - Similar to Fig.24 , Fig.26 Shows Figure 8 All hour and minute display devices of the watch, and a trigger lever specific to the hour mechanism, which includes a combined hour roller with an inner roller in an outer roller, such as a minute roller and an hour tens roller; as in the case of the minutes, a ten-hour drive mechanism surrounds the display device group and operates similarly to the drive mechanism of the minutes; the two trigger levers for the inner hour roller and the outer hour roller are also juxtaposed and arranged to cooperate with a single hour cam and with a combined twenty-four-hour mobile device including a twenty-four-hour cam and a twelve-hour cam; the operation of the hour elapsed is similar to Figures 9 to 25 The only notable change in the passage of minutes shown in the is the presence of a twelve-hour cam (similar in its operation to the ten-minute cam);

[0037] - Fig. 27 The twenty-four hour mobile is schematically and in perspective, comprising a twelve-hour cam of the lever of the inner roller, a twelve-hour cam of the lever of the outer roller, and a correction cam for managing certain time periods (midnight, 1 a.m.) to ensure the change from displaying "4" to displaying "0"; this correction cam cooperates with the correction lever, as described in detail below;

[0038] - Figures 28 to 30 The synchronization between the minute display and the hour display of the current time, that is to say a time other than midnight, is illustrated schematically, partially and in perspective:

[0039] - Fig.28The triggering lever of the inner hour units roller is shown a few minutes before the time change, similar to the corresponding part for the minutes and with its contact finger just leaving the hour cam; this lever comprises a second finger arranged to cooperate bearingly with a lug included in the clover of the minute tens roller, which prevents the lever from descending as long as the minute tens roller has not made its rotation;

[0040] - In with Fig.28 At the same time, Fig.29 The same mechanism is shown, in which the trigger lever of the inner hour units roller is not shown in order to allow the trigger lever of the outer hour units roller to be seen, whose contact finger has also just left the hour cam; this lever comprises a second finger arranged to cooperate in a bearing manner with a lug included in a drive clover kinematically connected to the minute Maltese cross system and which, in the same way, prevents the lever from descending until the minute Maltese cross has made its rotation;

[0041] - Fig.30 Shows Fig.28 and 29 just after the minutes tens roller has rotated between its position "5" and its position "0", during which rotation the two lugs leave the path of the rod, which allows the rod to descend and therefore allows the hours units roller to be driven;

[0042] - Similar to Fig.26 , Fig.31 The diagram shows a mechanism related to the hours, which includes a corrector lever for the hours units juxtaposed with the trigger lever of the inner hour units roller, and a corrector lever for the hours tens juxtaposed with the trigger lever of the outer hour units roller; the assembly is shown in the position at 23:59;

[0043] - Fig.32 Schematically and in perspective, an hour units corrector lever is shown, comprising a lateral projection which bears on a countersunk hole of a trigger lever of an inner hour units roller and comprising a drive finger arranged to be placed next to its drive finger and to cooperate with a drive star of the same inner hour units roller; when switching to midnight, the hour units corrector lever descends to drive the inner hour roller twice and allows switching from the display "3" to the display "0" without passing through the display "4"; the same applies to 1 a.m.;

[0044] - Fig.33 It is a detail of the synchronous cooperation between these two levers by bearing on each other, the lateral protrusion bearing on the countersunk hole (shown transparent) of the trigger lever of the inner hour units roller; when said trigger lever is released and descends, the hour units correction lever descends together with the trigger lever of the inner hour units roller;

[0045] - Fig.34Schematically and in perspective, the units and tens corrector levers are shown together, one of the arrangements required to allow switching from the display "2" to the display "0" at midnight, as will be discussed below, without operating the tens drive mechanism via the Maltese cross; the tens corrector lever is lowered a few minutes before midnight and is supported on the units corrector lever via a synchronizer, the synchronizer being a shaft carried by the tens corrector lever, the shaft being parallel to the common pivot axis of the levers and the bearing surface of the shaft cooperating with the bearing surface of the units corrector lever;

[0046] - Fig.35 Schematically and in perspective, together and juxtaposed, are shown a trigger lever for the inner hour roller and an hour units corrector lever, the combination of which allows specific display switching, including direct switching of the inner hour roller from position "3" to position "0" without rotating the outer roller, and switching of the hour tens roller from position "2" to position "0" without rotating the Maltese cross of the tens drive mechanism; in order to allow direct switching of the inner hour roller from position "3" via position "4" to position "0" without rotating the outer roller, the hour units corrector lever carries a pivoting hook that cooperates with a hook actuator carried by the trigger lever for the inner hour roller; as shown in Fig.33 In the embodiment of the present invention, it can be seen that the driving fingers of the two levers are juxtaposed, the said driving fingers being arranged to cooperate with the same driving star of the inner hour roller; the hour unit corrector lever comprises a contact finger arranged to cooperate with the combined twenty-four hour mobile and in particular with its outer track; the switching from position "3" to position "4" is conventionally controlled by the driving finger of the trigger lever for the inner hour roller, while the hook leaves the hour unit corrector lever immobilized; and, at the end of the travel of the trigger lever for the inner hour roller, its hook actuator releases the hook and allows the hour unit corrector lever released by the twenty-four hour mobile to descend, and its driving finger controls a new rotation of the star of the inner hour roller to display position "0";

[0063] The present invention relates to a roller jumping timepiece display mechanism 100. The mechanism 100 is an instantaneous jumping mechanism.

[0064] The accompanying drawings illustrate a specific and non-limiting case in which the display mechanism 100 is designed to be integrated into a timepiece, in particular a watch 1000; and in a non-limiting embodiment, more particularly constitutes a module of small dimensions, in particular having a diameter of around 37 mm and a height of approximately 12 mm; and is illustrated here in a non-limiting application for displaying hours in two digits and minutes in two digits.

[0065] The height constraints determine some of the construction choices applied to the watch, which will be detailed below; in the case of a pendulum, where the size constraints are less, the mechanism can naturally be simplified.

[0066] The accompanying drawings illustrate non-limiting variants in which the display mechanism is separate from the basic movement and may in particular constitute an independent additional module. In a variant not shown, the mechanism may integrate all or part of the basic movement, for example under the return spring of the lever, as will be presented later.

[0067] More particularly, for displaying the quantity, the mechanism 100 comprises at least one display device comprising a roller 1 , 1A, 1B, 2 , 3 , 3A, 3B, 4 and / or a combined roller 10 .

[0068] Such a combined scroll wheel 10 comprises at least two scroll wheels 1A, 1B, 3A, 3B, one of which is located inside the other, the outer scroll wheel 1A, 3A comprising at least one scroll wheel aperture 1C, 3C arranged to allow viewing or reading the inner scroll wheel 1B, 3B. In the illustrated non-limiting variant, the scroll wheel or combined scroll wheel comprises numbers etc. having a height of 2.8 mm, which matches a six-position scroll wheel having an outer diameter of 6.60 mm (or 6.00 mm for the inner scroll wheel in the case of a combined scroll wheel). This arrangement ensures readability and minimized space requirements.

[0069] The display of numbers requires ten positions, for example positions 0 / 1 / 2 / 3 / 4 on the inner wheel and positions 5 / 6 / 7 / 8 / 9 on the outer wheel, that is, five positions on each wheel.

[0070] More particularly, each scroll wheel 1 , 1A, 1B, 2, 3, 3A, 3B, 4 or each combined scroll wheel 10 comprises at most six display positions in order to ensure good readability for the user.

[0071] Thus, the outer scroll wheel may include an aperture instead of displaying a position, and the inner scroll wheel may advantageously include two zero positions according to an arrangement of 0 / 1 / 2 / 3 / 4 / 0, which allows kinematic simplifications as will be seen later. The outer scroll wheel may include an arrangement of 5 / 6 / 7 / 8 / 9 / (), the trailing symbol "()" corresponding to the aperture opening.

[0072] Figure 6 and Figure 7 A non-limiting encoding system for the embodiments illustrated in the accompanying drawings is detailed.

The driving mechanism 50M, 50H will be described in detail later.

[0084] More specifically, as can be seen in the embodiment illustrated in the accompanying drawings, the mechanism 100 comprises at least one upstream display device assembly 200, wherein the rotation of the upstream rollers 1, 2 constituting the upstream display device assembly 200 is controlled by upstream triggering bars 11, 12, and the upstream display device assembly 200 is arranged to cooperate with a downstream display device assembly 300, wherein the downstream display device assembly 300 is juxtaposed with the upstream display device assembly 200, and wherein the rotation of the downstream rollers 3, 4 constituting the downstream display device assembly 300 is controlled by downstream triggering bars 13, 14. The mechanism 100 comprises at least one such correction bar 15, 16, which is arranged to cooperate with one of the downstream triggering bars 13, 14, and a mechanism 17 for synchronizing the bars between the correction bars 15, 16 when the mechanism 100 comprises a plurality of correction bars, so as to control the rotation of at least one display device of the downstream display device assembly 300 in its proper position at the end of the cycle of the upstream display device assembly 200.

[0085] More particularly, the mechanism 100 is arranged to display the value of at least one quantity on a display device group 90M, 90H, which display device group 90M, 90H includes at least two display devices that are coaxial and juxtaposed to each other, each display device being composed of a roller 1, 1A, 1B, 2, 3, 3A, 3B, 4, or a combined roller 10.

[0086] More particularly, at least one display device group 90M, 90H includes an internal jump control mechanism for triggering rotation of one display device at the end of a cycle of another display device juxtaposed with one of the display devices included in the display device group 90M, 90H.

[0088] More particularly, the mechanism 100 is designed to display the value of at least one quantity on a display device group 90M, 90H, which display device group 90M, 90H includes at least two coaxial and juxtaposed basic display devices, each basic display device being composed of such a roller 1, 1A, 1B, 2, 3, 3A, 3B, 4 or a combination roller 10.

[0090] More particularly, the mechanism 100 is arranged to display the values ​​of at least two quantities, each quantity being displayed on at least one display device or group of display devices 90M, 90H, and all display devices or groups of display devices 90M, 90H are coaxial and juxtaposed two by two.

[0091] More particularly, at least one trigger rod or correction rod 11, 12, 13, 14, 15, 16 is arranged to cooperate with at least one cam 21, 22, 23, 24, 244, 245, 246, 247 to form a jump control mechanism, which is used to trigger the rotation of one display device of the display device group 90M, 90H at the end of the cycle of another display device of another display device group 90M, 90H juxtaposed with one display device of the display device group 90M, 90H.

[0092] Advantageously, the mechanism 100 comprises a roller synchronization mechanism for triggering the rotation of another upstream display device of another display device group 90M, 90H juxtaposed with said downstream display device of the display device group 90M, 90H at the end of a cycle of said downstream display device. The roller synchronization mechanism comprises a blocking device 1380, 1490 of each downstream trigger lever 13, 14 arranged for rotation control of the downstream display device 3, and the upstream display device 2 itself, the blocking device 1380, 1490 bearing on the lugs 528, 579 carried by the drive mechanism 50 of the upstream display device 2, to block the rotation of each downstream trigger lever 13, 14 during some display phases, and to synchronize the jumps of the at least two display device groups 90M, 90H. The detailed operation will be explained below.

[0093] More particularly, the mechanism 100 is arranged to display the values ​​of at least two quantities on at least two display device groups 90M, 90H that are coaxial and juxtaposed to each other.

[0094] The accompanying drawing illustrates a mechanical digital display of hours and minutes.

[0095] The minutes are displayed by the minute units wheel 1 and the juxtaposed minute tens wheel 2, which are visible together, in particular, through the minute aperture 5. Figure 3The minute units roller 1 shown in FIG. 1 is such a combined roller 10 and comprises an inner roller 1B visible through an opening 1C of an outer roller 1A. The two rollers 1 and 2 form a first display device group 90M, which is a minute display device group.

[0096] The hour is displayed by the hour units roller 3 and the hour tens roller 4 juxtaposed thereto, which are visible together in particular through the hour aperture 6. The hour units roller 3 is such a combined roller 10 and comprises an inner roller visible through the aperture 3C of the outer roller 3A. Figure 3 B. The two rollers 3 and 4 form a second display device group 90H, which is an hour display device group.

[0097] Figure 1 A dial 7 is illustrated carrying apertures for minutes 5 and hours 6 and mounted above a plate 8 carrying the rollers and other components of mechanism 100 .

[0098] Figure 2 Various trigger and correction levers are shown, from left to right:

[0099] - Lever 11 for actuating the minutes position of the inner roller;

[0100] - Lever 12 for actuating the minutes position of the outer roller;

[0101] - Lever 15 for correcting the units of the hours;

[0102] - Lever 13 for actuating the units of the hours on the inner roller;

[0103] - a lever 14 for actuating the units of the hours on the outer roller;

[0104] - Lever 16 for correcting the tens of the hours,

[0105] Its functions are described in detail below.

[0106] In a specific and non-limiting manner, the rollers pivot about a common axis R; in a specific and non-limiting manner, the levers pivot about a common axis B.

[0107] Figure 3 The minute roller 1 according to the present invention is shown as a combined roller 10, which includes an inner minute roller 1B, an outer minute roller 1A with its minute aperture 1C, and an assembly 1 consisting of the inner roller 1B mounted in the outer roller 1A (shown separately from left to right). The hour roller 3 is similarly constructed, having an inner hour roller 3B, an outer hour roller 3A with an aperture 3C.

[0108] More particularly, at least one display device group 90M, 90H includes at least two rollers, one of which is displayed as an integer multiple of the unit value of the other roller. More particularly, each display device group 90M, 90H includes at least two rollers, one of which is displayed as an integer multiple of the unit value of the other roller.

[0109] For such at least one display device group 90M, 90H, the display mechanism 100 includes at least one drive mechanism 50, for example, in the illustrated embodiment, a minute tens drive mechanism 50M and an hour tens drive mechanism 50H. The purpose of the drive mechanism 50 is to rotate the multiple roller by one position when the approximate roller has made one or more rotations corresponding to all its display sequences in the multiple step. Except for the exceptions that will be detailed below, the multiple roller (tens in this embodiment) is therefore not driven by a rod, but by such a drive mechanism 50.

[0110] The driving mechanism 50, here the tens minute driving mechanism 50M or the tens hour driving mechanism 50H, is driven by an approximate roller, here the ones roller.

[0111] Each display device group 90M, 90H thus comprises at least two rollers 1, 1A, 1B, 2, 3, 3A, 3B, 4 kinematically connected by such a drive mechanism 50, which comprises, in a non-limiting manner illustrated in the accompanying drawings, a Maltese cross 53, 55 arranged to be rotated by a pin 109, 319 fixed to the sub-number roller and to rotate integrally with a lug-carrying star 51, 56 arranged to drive, through one of its lugs 511, 561, through radial slots 529, 541, a clover 52, 54 carried by the multiple roller. Here, the sub-number (that is to say the ones) roller rotates the Maltese cross, which drives the lug star, which in turn drives the multiple roller (here the tens). Minute units roller 1 and hour units roller 3 thus carry a pin 109 , 319 , respectively, arranged to cooperate with a radial groove 531 , 551 included in minute Maltese cross 53 or hour Maltese cross 55 .

[0112] Figure 4A minute tens roller 2 is shown, which laterally carries a minute tens clover 52 comprising six radial grooves 529 arranged to cooperate with star lugs 511 included in a star 51 with lugs coupled to a minute Maltese cross 53. This minute tens clover 52 carries a bearing lug 528, here in the shape of a cubic block, arranged to serve as an abutment support for a lever limiting finger 1380 included in the hour trigger lever 13 of the inner roller, as will be described below.

[0113] More generally, the clover 52 , 54 or the multiple rollers carry a bearing lug arranged to act as an abutment support for a lever-limiting finger included in the trigger lever 11 , 12 , 13 , 14 .

[0114] The lug-carrying star-shaped members 51, 56 of the drive mechanism 50 of the upstream display device 2 are advantageously arranged to rotate a drive axle clover-shaped member 57 about an axis parallel to its axis, which carries a rod abutment lug 579, which is arranged to serve as an abutment support for a rod abutment finger 1490 included in the trigger lever 11, 12, 13, 14.

[0115] Figure 5 The hour tens roller 4 is shown, which carries the clover 54 in a similar manner (in Fig.45 ), and its axis comprises a driving square 4160 and it carries laterally three planetary carrier bolts or pivots 72 for a release mechanism 70 (described hereinafter). This release mechanism 70 has the function of releasing the drive mechanism 50 to allow position correction of the rollers 1, 1A, 1B, 2, 3, 3A, 3B, 4 directly through the correction rods 15, 16 and not through the drive mechanism 50.

[0116] The mechanism 100 advantageously comprises at least one composite roller 10, whose inner rollers 1B, 3B are arranged to be rotated by inner roller trigger levers 11, 13 and whose outer rollers 1A, 3A are arranged to be driven by outer roller trigger levers 12, 14 or by a first correction lever 15. In particular, such a composite roller 10 is a submultiple roller.

[0117] Inner roller 1B, 3B is also arranged so that, at certain moments predetermined and controlled by twenty-four hour mobile 24 driven by movement 500, first correction lever 15 causes it to rotate. This first correction lever 15 is juxtaposed with inner roller trigger lever 11, 13 and cooperates therewith by virtue of the cam of twenty-four hour mobile 24. First correction lever 15 comprises a lateral projection 151 which bears on countersunk hole 135 of inner roller trigger lever 113. This projection 151 bears on countersunk hole 135 shortly before the jump controlled by cam 21, 23 on which contact 2111, 2313 included in inner roller trigger lever 11, 13 bears. Correction lever 15 also comprises a drive finger 1501 which is arranged to be placed next to drive fingers 1101, 1301 of inner roller trigger levers 11, 13 and to cooperate with the same star-shaped members 411, 413 of the inner rollers 1B, 3B, whereby, when the inner roller trigger levers 11, 13 descend at the moment controlled by cams 21, 23 and for the jump permitted by the twenty-four hour mobile 24, the first hour units corrector lever 15 also descends to subsequently drive star-shaped members 411, 413, thus driving the inner rollers 1B, 3B twice.

[0118] In general, each roller comprises an axle capable of supporting a star so as to cause it to rotate, the axle in particular carrying a square: in particular, in the figures we can see square 4120 for driving roller 1, square 4140 for roller 3 and square 4160 for roller 4. It should be noted that some rollers are not necessarily driven by a lever: this is the case of the tens minute roller 2, which is driven by the Maltese cross of the tens minute drive mechanism 50M.

[0119] Figure 6 The code for the minute display is shown, according to which a specific non-limiting variant of the mechanism illustrated by the accompanying drawings is based on Figure 3 and Figure 4 The rollers of the invention are constructed in accordance with the invention. In this particular case, in the combined roller 10 for displaying the minute digit 1 and the hour digit 3, the inner rollers 1B, 3B respectively comprise six positions: 0, 1, 2, 3, 4, 5, 0. The outer rollers 1A, 3A respectively comprise six positions: 5, 6, 7, 8, 9, (). Double brackets or square brackets are used to encode the openings included in the rollers in question. As can be seen in the drawings comprising many identical basic components, this particular configuration allows for maximum number, identical drive lever strokes for both rollers, and identical star-positioning lever assemblies in a minimum space requirement.

[0120] Figure 6 The minutes table in consists of six columns:

[0121] - Column 1: value of tens wheel 2;

[0122] - Column 2: value of outer units roller 1A;

[0123] - Column 3: Value of inner units roller 1B:

[0124] - Column 4: number of rotations of the roller in column 2;

[0125] - Column 5: number of rotations of the roller in column 3;

[0126] - Column 6: Number of rotations of the wheel in column 1.

[0127] One row corresponds to one minute.

[0128] The double or square brackets correspond to the opening of the roller.

[0129] Figure 6 The table in shows only the minute display from "00" to "30" because it can be noticed that there is a periodicity of ten minutes.

[0130] It is noted that within a ten minute period, the inner roller 1B and the outer roller 1A each rotate six times.

[0131] More specifically, whenever the units position "5" is displayed, the inner roller 1B also rotates so as to pre-position itself to the value "0" in preparation for displaying "0" in the next ten.

[0132] Therefore, the minute display requires a minute cam 21 and a ten-minute cam 22 .

[0133] Similarly, Figure 7 The hour table in contains seven columns:

[0134] - Column 1: value of the tens wheel 4;

[0135] - Column 2: value of outer units roller 3A;

[0136] - Column 3: Value of inner units wheel 3B:

[0137] - Column 4: number of rotations of the roller in column 2;

[0138] - Column 5: number of rotations of the roller in column 3;

[0139] - Column 6: number of rotations of the roller in column 1;

[0140] - Column 7: Needs correction, especially by double rotation.

[0141] One row corresponds to one hour.

[0142] Figure 7 The table in shows the display for the hours "00" to "24".

[0143] Note that columns 4 and 5 of the hourly table have a twelve hour periodicity.

[0144] Column 7 shows that the inner roller 3B has to rotate twice when switching from position "23" to position "00" and when switching from position "00" to position "01".

[0145] Column 6 shows that when a switch is made at midnight, which does not fit into the general framework, the roller must be actuated by a specific mechanism.

[0146] Therefore, the hour display requires hour cam 23 and twelve-hour cam ( Figure 7 4 and 5 of the table), which will be described in the following form: Figure 7 The first twelve hours of column 4 of the table cam 244, and corresponding to Figure 7 The second twelve-hour cam 245 and the twenty-four-hour cam 246 of column 5 of the table ( Figure 7 6 of the table), and here the correction cam 247 including the recess 249 ( Figure 7 7 of the table). Fig. 27 As shown in FIG. 1 , in the illustrated non-limiting embodiment, a single twenty-four hour mobile 24 groups together the twelve hour cam, the twenty-four hour cam and the correction cam.

[0147] The reader may refer to these tables to understand some specific display change configurations, which will be described below.

[0148] Figure 8 The display devices are separated: in the right part, the first display device group is the minute display device group 90M, and includes from right to left Figure 3 The minute wheel 1 and Figure 4 and in the left part, the second display device group is the hour display device group 90H, and includes from right to left the hour digit roller 3 and Figure 5 Hour tens roller 4. These four rollers are here coaxial with the rotation guide shafts 912 and 934 with a common axis R and some are connected to a drive star held in a stationary position by a positioning lever:

[0149] - inner minute roller 1B is integral with star 411 held by jumper 311;

[0150] - outer minute roller 1A integral with star 412 held by jumper 312;

[0151] - inner hour roller 3B is integral with a star 413 held by a positioning lever 313; it will be seen later that this same star 413 is arranged to cooperate simultaneously with two levers, including the trigger lever and the correction lever for some switching configurations, which explains the double width of star 413;

[0152] - the outer hour roller 3A is integral with a star 414 held by a positioning rod 314;

[0153] - Hour tens wheel 4 is integral with a star 416 held by jumper 316 for its cooperation with the correction lever, which is required for the switching problem at midnight in this particular type of display device.

[0154] In the present application, the minute tens roller 2 is not connected to the star; however, a different coding of the roller may require such a connection, in which case its housing should be treated similarly to the hour tens roller 4, which is used for the cooperation of the hour tens roller 4 with the corrector rod 16 described below.

[0155] This minute tens roller 2 carries laterally a clover 52 in order to drive it via a drive mechanism 50M with a Maltese cross.

[0156] The hour tens roller 4 laterally carries a clover 54 similar to the one carried by the minute tens roller 2 and having radial grooves 541; this clover 54 is integral with the self-closing wheel 73 of the release mechanism 70, in the teeth of which the idler wheel mounted on the release mechanism 70 can be blocked. Figure 5 The planet wheel 71 on the planet wheel carrier bolt or pivot 72 is engaged to rotate the hour tens roller 4 by engaging the self-locking wheel 73, and the disengagement of the planet wheel 71 causes release.

[0157] The units rollers 1, 3 carry pins 109, 319 which are arranged to cooperate with the minute Maltese crosses 53, 55 for driving the tens rollers 2, 4 during most switching periods, except for special switching to a particular hour, which will be described in detail below.

[0158] Figures 9 to 30The switching of the minutes is shown. This shows the operation of the minute trigger lever 11 pivoted about the lever axis B for controlling the inner roller 1B of the combined minute units roller 1. The lever 11 is subject to the action of a return spring 119 which tends to press the drive finger 1101 included in the lever 11 against the star 411 included in the inner roller 1B, and the star 411 in turn is subject to the return torque of the positioning lever 311 to keep it in the stationary position. The lever 11 carries, between its pivot and its distal drive finger 1101, on the one hand, a ten-minute contact finger 2211 arranged to cooperate in a supporting manner with the ten-minute cam 22, which is a slit-type straight-edge cam; and on the other hand, a minute contact spindle 2111 (at the bottom of the lever 211) arranged to be supported on the substantially helical track of the minute cam 21. Fig.15 This substantially spiral track enables the contact of each rod following the cam to spiral upwards before it jumps. The contact is in particular a ruby ​​roller or the like to reduce friction.

[0159] The minute cam 21 includes a device for preventing the contact spindle 2111 from leaving the high point of the cam 21 (which is Fig. 9 any device moving backwards at the moment of the jump. Fig.16 The device is illustrated: the cam 21 itself pivots on the cam base 210, the pin 212 integral with the cam 21 slides in the pod-shaped slot 211, which limits the travel. Thus, during descent, the pin 212 and therefore the cam 21 pops up tangentially a little further into the slot 211 and allows the rod 11 to descend, and any undesired recoil movement is avoided.

[0160] Fig.10 The diagram shows the switching of the minutes digit when the ten-minute contact finger 2211 is not stopped by the release of the ten-minute cam 22, and just after the jump of the contact spindle 2111, when the descent of the rod 11 just drives the star piece 411 of the roller 1B which has rotated one position.

[0161] Figures 11 to 14 It is a detail of the sequence of cooperation between, on the one hand, the drive finger 1101 forming a movable assembly 80 pivotally mounted on a pivot 84 and comprising an elastic blade 81 movable between a front abutment 82 and a rear abutment 83, and on the other hand, the star 411 of the roller 1B. Fig.11In the rest position of the rod 11, the elastic blade 81 bears on the first front abutment 82 situated on the side of the star 411. The contact of the finger 1101 with the star 411 occurs during the descent of the rod 11, the blade 81 leaves the first abutment 82 and the finger begins to pivot, its blade 81 approaching the second rear abutment 83. When the blade 81 contacts the second abutment 83, the star 411 pivots and the rod 11 accompanies the star 411 during approximately two thirds of its step before reaching its abutment, which ensures the passage of the top of the positioning rod 311.

[0162] When rod 11 rises, finger 1101 is free until blade 81 returns to support on first limiting abutment 82; blade 81 is weaker than positioning rod 311 of star 411, and blade 81 bends to pass over the top of star 411, so that the star cannot be driven again by finger 1101.

[0163] Fig.18 A minute cam 21 is shown which comprises a substantially helical track which is wide enough for the two contact spindles 2111 and 2112 comprised in two adjacent levers 11 and 12 to traverse simultaneously.

[0164] Fig.17 The minute trigger lever 11 for controlling the inner roller is shown together, juxtaposed with the minute trigger lever 12 for controlling the outer roller, its contact spindles 2111 and 2112 therefore crossing the same spiral track of the cam 21, and its ten-minute contact fingers 2211 and 2212 are both arranged to cooperate with the same ten-minute cam 22, which allows or prohibits the descent of the corresponding lever 11 or 12.

[0165] Fig.19 The same components are shown in the position they occupied a few seconds before the jump, with reference to Figure 6 , in the minute display position “04” in which the units of the minute display “4”, wherein the outer roller 1A has an aperture 1C (column 2 of the table), while the inner roller 1B has the number 4 (column 3 of the table); the mechanism is ready to switch to the global display position “05” in which the units of the minute display “5” is displayed, wherein the outer roller 1A shows the number 5 (column 2), while the inner roller 1B returns to the position in which it has the number 0 (column 3) and is thus ready to anticipate the switch to the next ten minutes, wherein the inner roller 1B will have its number 0 in the aperture 1C of the outer roller 1A. It can be seen that the two ten-minute contacts 2211 and 2212 are not hindered by the ten-minute cam 22, and that the two levers 11 and 12 can descend when the time is reached so as to continue to rotate both the inner roller 1B and the outer roller 1A in a synchronized manner. Fig. 20 This is the situation after the jump, in the configuration showing the value “05”, in which neither lever 11 nor 12 is blocked by the ten-minute cam 22 .

[0166] Fig.21 The same assembly is shown after a jump to the value "6" in another display position, wherein the inner roller 1B does not rotate and remains in its display position because the lever 11 corresponding to the display of the inner roller 1B is blocked by the ten-minute cam 22, the contact finger 2211 of the lever 11 abuts against the slot of the ten-minute cam 22, and therefore the inner roller 1B does not rotate, and only the lever 12 associated with the outer roller 1A descends and pivots the outer roller 12.

[0167] Fig. 22 and Fig.23 The diagram shows a ten-minute drive mechanism 50M, the principle of which is also used to trigger the ten hours in another hour display device group 90H. This mechanism surrounds the display device group 90M including the combined minute unit roller 1 and the single minute tens roller 2; this mechanism is a mobile device, the axis of which is parallel to the common axis R of the axes of the various rollers, and includes a minute Maltese cross 53 on the side of the combined minute unit roller 1, the groove 531 of which is arranged to engage with the pin 109 ( Fig.17 and includes a lug-bearing star 51 on the side of the minute tens roller 2 and rotating integrally with the minute Maltese cross 53, the lug 511 of the lug-bearing star 51 being arranged to rotate with the minute tens roller 2. Figure 4 The minute tens digit axle 52 is matched with the groove 529 of the clover-shaped piece 52.

[0168] Fig.24 and 25 The diagram shows the passage of the tens place. Fig.24 The same assembly is shown in the position it occupies a few seconds before the jump, in global display position “09”, with the display position of the units of the minutes being “9”, with outer roller 1A having the number 9 (column 2) and inner roller 1B having the number 0 (column 3); the mechanism is ready to switch to global display position “10”, with the tens roller switching to position “1” (column 1) until then in display position “0”; and at combined units roller 1, outer roller 1A having its aperture 1C (column 2) through which inner roller 1B will continue to display “0” (column 3) without rotating; the groove 531 of the minute Maltese cross 53 of the units of the minutes co-operates with the claw 109 of the units roller 1. Fig.25 The same assembly is shown after a jump, in global display configuration "10", in which neither of the two levers 11, 12 is stopped by the ten-minute cam 22; the outer roller 1A of the combined minute units roller 1 pivots and its claw 109 rotates the minute Maltese cross 53, which at the other end rotates the ten-minute clover 52 and, therefore, the ten-minute roller 2.

[0169] The display and switching of the hours are performed in a similar manner. The hour display device group 90H includes the hour unit display device roller 3 and the hour ten display device roller 4. As in the case of the minutes, the hour ten drive mechanism 50H surrounds the display device group 90H and operates similarly to the operation of the minutes; the rod 13 for triggering the hours of the inner roller and the rod 14 for triggering the hours of the outer roller are also juxtaposed and arranged to cooperate with a single hour cam 23 and with a combined twenty-four hour mobile device 24, which in particular includes a twenty-four hour cam and a twelve hour cam. The operation of the hour switching is similar to the minute switching discussed above, the only significant change being the presence of a twelve hour cam instead of a ten minute cam. It should be understood that the present invention can be used for any display device combination, one of which displays a multiple of the other, and can be used for any display range. Of course, the coding of the various rollers and the nature of the cams and correction rods must be adapted to each case. For example, the roller can occupy four, or six, or ten, or even twelve positions, and the multiple coefficient between two rollers of the same display device group can also be four, or six, or ten, twelve positions or other, which can be used for other displays, such as calendar, moon phase, tide, etc. Therefore, depending on the configuration of the roller, the drive mechanism 50 can also generate the drive of the multiple roller with a coefficient other than ten (for example four, six, twelve, etc.).

[0170] More specifically, the twenty-four hour mobile 24 comprises here a first twelve hour cam 244 of the trigger lever 13 of the inner hour roller, a second twelve hour cam 245 of the trigger lever 14 of the outer hour roller, and a twenty-four hour cam 246, and a correction cam 247 for managing some time changes: midnight, 1 a.m., and in particular ensuring the switch from the display "4" to the display "0". This correction cam cooperates with the correction levers 15 and 16, as described in detail below.

[0171] The invention requires the presence of a synchronization mechanism between the display of the minutes and the display of the hours, in particular when it comes to the current time, that is to say a time other than midnight.

[0172] The mechanical system transmits the instantaneousness of the beats from the ones wheel to the tens wheel both for the hours and for the minutes, thanks to the corresponding tens drive mechanism via the Maltese cross, the lug clover and the drive clover.

[0173] The jump of the hour unit digit needs to be synchronized with the ten minutes, because when "59" is displayed on the minute display device 90M, when switching from position "59" to position "00", the hour unit digit roller 3 needs to rotate synchronously.

[0174] The trigger lever 13 of the inner hour unit roller and the trigger lever 14 of the outer hour unit roller driving the two hour unit rollers 3B and 3A are lowered onto the lugs for preparation a few minutes before the time elapses.

[0175] therefore, Fig.28 The trigger lever 13 of the inner hour units roller is shown a few minutes before the time change, which is similar to the trigger lever 11 of the inner minute units roller and whose contact finger 2313 has just left the hour cam 23. This trigger lever 13 of the inner hour units roller includes a second lever limiting finger 1380, which is arranged to cooperate in a supporting manner with the lug 528 included in the axle clasp 52 of the minute tens roller 2, which prevents the lowering of the trigger lever 13 of the inner hour units roller as long as the minute tens roller 2 does not make its rotation.

[0176] Similarly, Fig.29 In with Fig.28 The same mechanism is shown at the same time, wherein the trigger lever 13 of the inner hour roller is not shown so as to be able to observe the trigger lever 14 of the outer hour roller, whose contact finger 2314 has also just left the hour cam 23; this trigger lever 14 of the outer hour roller also includes a second lever abutment finger 1490, which is arranged to cooperate in a supporting manner with a lug 579 included in the drive axle clover 57, which is kinematically connected to the minute Maltese cross system and in the same way, as long as the minute Maltese cross 53 does not make its rotation, this prevents the trigger lever 14 of the outer hour roller from falling. In particular, as Fig.29 As can be seen in FIG. 1 , the drive clover 57 is rotatably mounted on an axis parallel to the axis of the minute Maltese cross 53 .

[0177] When the minute tens roller 2 rotates to switch from the display position “5” to the display position “0”, the two pins 528 and 579 leave the paths of the corresponding rods 13 and 14, which can then descend. Fig.30 These two levers 13 and 14 are shown just after the minute tens roller 2 has rotated between its position “5” and its position “0”, the lowering of which allows the hour units roller 3 to be driven.

[0178] Fig.31 The entire mechanism associated with the hours is shown, comprising the hours units correction lever 15 juxtaposed with the trigger lever 13 of the inner hours units roller, and the hours tens correction lever 16 juxtaposed with the trigger lever 14 of the outer hours units roller; the assembly is shown in the position of 23:59. The figure also shows two tens drive mechanisms. Figure 7The table in shows the switching of the tens digits of the hours, in particular the switching from "23" to "00", which does not follow the conventional switching diagram from "03" to "04" and from "13" to "14", because if the same logic is followed, the switching display will switch from "23" to "24", while the expectation is always to display "00" instead of "24" to show the first hour of the early morning; this does not exclude a variant with a very brief momentary display of "24" "00" between the normal display of "23" "59" and "00" "00", where each display remains visible for about one minute.

[0179] In order to switch from display "23" to display "00", it is usually necessary to switch the inner hour units roller 3B from position "3" to position "4" and then to position "0" so that the outer hour units roller 3A does not rotate, and to switch the hour tens roller 4 from position "2" to position "0" without rotating the hour Maltese cross 55 of the hour tens drive mechanism.

[0180] Fig.32 and 33 The hour units correction lever 15 is shown, which includes a lateral protrusion 151, which is supported on the countersunk hole 135 of the trigger lever 13 of the inner hour units roller, and a few minutes before the jump, the protrusion 151 is supported on the countersunk hole 135, which is then in a ready state. The hour units correction lever 15 includes a drive finger 1501, which is arranged to be placed next to the drive finger 1301 of the trigger lever 13 of the inner hour units roller and cooperates with the drive star 413 of the same inner hour units roller 3B. When the trigger lever 13 of the inner hour units roller descends at midnight, the hour units correction lever 15 also descends when switching to midnight, which allows the inner hour roller 3B to be driven twice and allows switching from display "3" to display "0" without passing through display "4"; as in Figure 7 , which is the same at 1 a.m.

[0181] Fig.34 Shown together are the units-of-hours corrector lever 15 and the tens-of-hours corrector lever 16, which constitute an arrangement that allows switching from the display "2" to the display "0" at midnight without operating the tens drive mechanism via the Maltese cross 55. The tens-of-hours corrector lever 16 is lowered a few minutes before midnight and bears on the units-of-hours corrector lever 15 by means of a synchronizer, which is a shaft 17 carried by the tens-of-hours corrector lever 16, which is parallel to the common pivot axis B of the levers and whose bearing surface 172 cooperates with the bearing surface 152 of the units-of-hours corrector lever 15. Fig.34 The contact fingers 2415 and 2416 of the two rods 15 and 16 are again shown, both arranged to cooperate with a twenty-four-hour mobile device 24 that allows or prohibits the descent of these rods.

[0182] In order to allow direct switching of the inner rollers 1B, 3B by jumping between two positions without corresponding rotation of the outer rollers 1A, 3A, the correction lever 15 carries a pivoting hook 154 which cooperates with a hook actuator 138 carried by the trigger levers 11, 13 for driving the inner rollers 1B, 3B, so that at the end of the travel of the trigger lever 13, its hook actuator 138 releases the hook 154 and allows the correction lever 15 to descend, which is released by the twenty-four-hour mobile 24 for driving the inner rollers 1B, 3B.

[0183] The switching of the inner roller 3B for the hour units display from position "3" to position "4" and then to position "0" requires a specific arrangement, which is Figures 35 to 39 The switch from position "3" to position "4" is done as for each hour switch, but when the trigger lever 13 for the inner hour roller reaches the end of its travel, it pushes the pivoting hook 154, which is pivotally mounted on a pivot 153 integral with a fixed element such as a plate, and which releases the hour units corrector lever 15 to actuate the same star 413 for a second time and thus switch from position "4" to position "0".

[0184] Fig.35 The trigger lever 13 for the inner hour roller and the hour units corrector lever 15 are shown together and juxtaposed, the combination of which allows specific display switching, including direct switching of the inner hour roller 3B from position “3” to position “0” without rotating the outer roller 3A, and switching of the hour tens roller from position “2” to position “0” without rotating the hour Maltese cross 55 of the tens drive mechanism. In order to allow direct switching of the inner hour roller 3B from position “3” via position “4” to position “0” without rotating the outer roller 3A, the hour units corrector lever 15 carries a pivoting hook 154 that cooperates with a hook actuator 138 carried by the trigger lever 13 for the inner hour roller. The figure shows that the drive fingers 1301 and 1501 of the two juxtaposed levers 13 and 15 are arranged to cooperate with the same drive star 413 of the inner hour units roller. The hour corrector lever 15 comprises a contact finger 2415 arranged to cooperate with the combined twenty-four hour mobile 24 and in particular with its outer track; the switch from position "3" to position "4" is conventionally controlled by the drive finger 1301 of the trigger lever 13 for the inner hour roller, while the hook 154 prevents the hour corrector lever 15 from moving.

[0185] And, at the end of the stroke of the trigger lever for the inner hour roller 13, its hook actuator 138 releases the hook 154 and allows the hour units corrector lever 15 released by the twenty-four hour mobile device 24 to descend, and the driving finger 1501 of the hour units corrector lever 15 controls the new rotation of the star piece 413 of the inner hour roller 3B to display the position "0".

[0186] The hook actuator 138 is arranged to push the inclined track 158 of the pivoting hook 154. The lever 15 carries a pin support finger 152 which carries a blocking pin 156 which cooperates with the cylindrical track 155 of the hook 154 during part of its angular travel and which, under the pressure of the hook actuator 138, disengages the hook at the end of its angular travel. Fig.37 In the embodiment shown in FIG. 1 , the hook actuator 138 is supported on the inclined track 158 of the hook 154 and neither of the two levers 13 and 15 is pivoted. Fig.38 The diagram shows the beginning of the descent of the trigger lever 13 for the inner hour roller in order to switch from position "3" to position "4"; the hook actuator 138 pushes back the inclined track 158 and pivots the hook 154, which still cooperates with its pin 156 at its concentric cylindrical track 155 to immobilize the hour corrector lever 15. Fig.39 The diagram shows the end of the descent of the trigger lever 13 for the inner hour roller in order to switch from position "3" to position "4"; the hook actuator 138 pushes back the inclined track 158 of the hook 154 and pivots the hook 154, which disengages from its pin 156 and releases the hour units corrector lever 15, which also releases the hour units corrector lever 15, which can pivot and drive the inner hour units roller 3B towards position "0" through its drive finger 1501, which has just briefly switched to position "4" under the action of the descent of the trigger lever 13 for the inner hour roller; the twenty-four-hour mobile device 24 is arranged to allow the hour units corrector lever 15 to descend only twice a day, namely at midnight and at 1 a.m. For this purpose, the twenty-four-hour cam 247 has a notch 249 corresponding to this time range. The rest of the time, the hour units correction lever 15 remains on the upper portion of the twenty-four hour cam 247, which prevents it from falling and prevents it from rotating the star 413 of the inner hour units roller 3B.

[0187] The tens hour roller 4 is switched from position "2" to position "0" by the tens hour correction lever 16 (which is already in Fig.34 As shown in Fig.41As can be seen in the figure, the hour tens correction lever 16 cooperates with the 24-hour cam 246 located on the 24-hour mobile device 24, so that at midnight every day, the lever 16 is released to drive the star 416 connected to the hour tens roller 4, switching it from position "2" to position "0". However, it is then necessary to short-circuit the tens drive mechanism including the hour Maltese cross 55, because at midnight, the outer hour ones roller 3A is blocked from rotating, because the mechanism is in Fig.42 In the case of being in the blocked position at midnight, it is necessary to install the release mechanism 70.

[0188] A specific variation of the release mechanism 70 is Fig.41 The middle part is visible and is represented by Figures 43 to 47 Detailed illustration; the release mechanism 70 includes a self-blocking wheel 73 with a planetary wheel 71 similar to an automatic commutator to allow the rotation of the hour tens roller 4 independently of the driving clover of the hour Maltese cross 55 connected to the tens drive mechanism, which is then blocked. Fig.43 The cloverleaf 54 of the hour tens roller 4 is shown, beneath which the self-closing wheel 73 can be seen cooperating with planetary wheels 71, in particular but not limited to three planetary wheels 71, which pivot on three bolts or pivots 72 carried by the hour tens roller 4.

[0189] Fig.45 The conventional tens switching is shown. When the outer hour ones roller 3A switches from position "9" to position "0", it activates the hour Maltese cross 55, which rotates the clover 54 integral with the self-blocking wheel 73; the planetary wheel 71 has a specific irreversible shape and is blocked in the teeth of the self-blocking wheel 73, which rotates the hour tens roller 4; as seen in the figure, the self-blocking wheel 73 and the tens roller 4 rotate in the clockwise direction, and at least one planetary wheel 71 supports the teeth of the self-blocking wheel 73.

[0190] Fig.46 and 47 The diagram shows the switch from position "23" "59" to position "00" "00": the lever descends on star 416 of hour tens roller 4, causing star 416 to rotate also in the clockwise direction in the drawing; planet wheel 71 can then rotate freely around the self-locking wheel due to the shape of its teeth. More specifically, an angular offset is provided between the planet wheels to reduce blind spots.

[0191] Naturally, the release mechanism 70 may take other forms of construction, for example with a freewheel type mechanism allowing rotation in one direction and providing a clutch in the other direction by blocking the ball against the wall of a compartment which encloses the ball, or the like.

[0192] Some alternatives to the release mechanism 70 may therefore include two inlets.

[0193] The roller jumping type timepiece display mechanism 100 according to the present invention allows an original display in a small volume, which can constitute a main display or a sub-display alone or in combination or juxtaposition with other display devices.

[0194] The specific application described below is a timepiece 1000, in particular a watch, comprising at least one movement 500 for driving a main display mechanism and a secondary display mechanism. The example chosen relates to a Mars space mission: one of the display means is a display of days and hours relating to Earth and Earth time, while the other display produced by the roller jumping timepiece display mechanism 100 according to the invention is a display of days and hours relating to Mars and Mars time. In this specific case, the duration of a Martian solar day is 24.659790 Earth hours (approximately 24 Earth hours and 40 Earth minutes). Therefore, the ratio between the length of an Earth day and a Martian day is equal to 24 / 24.659790=0.973244296089269.

[0195] A suitable timepiece using a mobile with a reasonable number of teeth for use in a watch comprises a 22-tooth earth wheel and a 43-tooth chronograph wheel; the 22-tooth earth wheel performs one revolution while the 36-tooth chronograph pinion performs 0.6111 revolutions; the 43-tooth chronograph wheel cooperates with the 27-tooth Mars wheel, which then performs 0.973251028806584 revolutions. The error associated with this chronograph is very small, about 6.733*10 -6 , which corresponds to 4*10 -4 Earth minute, or 0.02424 Earth seconds, or 0.58171 seconds per Earth day.

[0196] There is therefore a speed of about 0.58 seconds per day: when the displayed Martian time changes from 23:59 to 00:00, the change occurs 0.58 seconds before Mars actually completes its rotation.

[0197] Of course, other gear ratios allow smaller errors to be achieved: a 19-tooth earth pinion and a 67-tooth chronograph wheel; the 19-tooth earth pinion performs one rotation when the 12-tooth chronograph pinion performs 1.583333 rotations; the 67-tooth chronograph wheel cooperates with the 109-tooth Mars pinion, which then performs 0.973241590214067 rotations. The error associated with this chronograph is about minus 0.23 seconds per day, but at the expense of a gear train with a large number of teeth, which would require much more volume.

[0198] Therefore, having a chronograph mechanism that is about 0.58 seconds fast per day is still a good solution for a watch, it being noted that this error is well below the operating error of many commonly used standard timepieces.

[0199] Fig.48 The gear train 600 is schematically shown, the sequence comprising:

[0200] - an earth wheel 610 which performs one rotation in 24 earth hours;

[0201] - a timer moving device 620;

[0202] - Mars wheel 630, which performs one rotation in 24.6596 Earth hours;

[0203] - Multiplication / reduction gear train 640;

[0204] - cam group 650, which includes minute cam 21, ten-minute cam 22, hour cam 23, twelve-hour cams 244 and 245, twenty-four-hour cam 246, and correction cam 247;

[0205] - a trigger lever and correction lever set 660, which includes a trigger lever 11 for the inner minute unit roller, a trigger lever 12 for the outer minute unit roller, a trigger lever 13 for the inner hour unit roller, a trigger lever 14 for the outer hour unit roller, a correction lever 15 for the hour unit, and a correction lever 16 for the hour tens;

[0206] - Display wheel set 670, which here includes a minute units wheel 1, a minute tens wheel 2, an hour units wheel 3, and an hour tens wheel 4.

[0207] Fig.49 The connection between the earth minute wheel 610 and the Mars minute wheel 630 via a chronograph mobile 620 is schematically shown, and the chronograph mobile 620 includes a chronograph pinion 621 and a chronograph wheel 622 .

[0208] Fig.50 6 is a perspective view of a multiplication / reduction gear train 640, which includes, from the Mars minute wheel 630 on which the hour cam 23 is located, a first reduction gear train 641 for driving the twenty-four hour mobile 24, and a second multiplication gear train 642 for driving the minute cam 21 and the ten-minute cam 22. The first reduction gear train 641 includes a chronograph mobile 643 for hours, a twelve-hour mobile 644, and a twenty-four-hour mobile 24. The second multiplication gear train 642 includes an intermediate mobile 645, a multiplication mobile 646, a minute mobile 647 carrying the minute cam 21, and a ten-minute mobile 648 carrying the ten-minute cam 22.

[0209] The invention can also be applied to a main time display, a secondary display, a second time zone, a chronograph or any other display.
