Description

Field of the invention

The invention relates to a roller jumping clockwork display mechanism.

The invention also relates to a timepiece, in particular a watch, comprising at least one movement arranged to drive cams that comprises such a jumping roller clockwork display mechanism.

The invention relates to the field of timepiece display mechanisms.

Background of the invention

It is often difficult to make different displays cohabit on a timepiece, especially when it is of small size like a watch.

And it is important to easily distinguish a primary display from a secondary display, without any risk of confusion.

One solution consists in using conventional displays, such as needles or discs, for a first display, and a roller display for a second display. However, a roller display for a watch requires a substantial volume, and is difficult to install in a watch. Furthermore, in order to avoid interpretation doubts when the time or day changes, it is preferable to produce an instantaneous jumping display, which is more complex. These constraints are further amplified when this second display concerns magnitudes with units different from those of the first display, which requires a conversion mechanism which further complicates the construction of the watch.

Summary of the invention

The invention proposes to develop a roller display for an instantaneous jump watch, thus offering the best guarantees of display, and of reasonable size, compatible with the volume of a watch.

The invention is described for the particular case of a watch for a space mission to the planet Mars, where the main display relates to the terrestrial time, while the secondary roller display relates to the Martian time.

To this end, the invention relates to a roller jumping clockwork display mechanism according to claim 1.

The invention also relates to a timepiece, in particular a watch, comprising at least one movement arranged to drive cams that comprises such a jumping roller clockwork display mechanism.

Detailed Description of Preferred Embodiments

The invention relates to a roller jumping timepiece display mechanism 100. This mechanism 100 is an instantaneous jump mechanism.

The figures illustrate a particular and non-limiting case where this display mechanism 100 is designed to be integrated into a timepiece, in particular a watch 1000, and constitutes more particularly, in a non-limiting embodiment, a module, of reduced dimensions , with in particular a diameter of the order of 37 mm and a height of approximately 12 mm, and illustrated here in a non-limiting application to the display of the hours on two digits and the minutes on two digits.

The height constraint determines certain construction choices, which are detailed below, for the application to a watch; the mechanism can of course be simplified in the case of a clock where the dimensional constraints are less.

The figures illustrate a non-limiting variant where the display mechanism is separate from the basic movement, and can in particular constitute an independent additional module. In a variant not illustrated, the mechanism can integrate all or part of the basic movement, for example under the return springs of the rockers, which will be presented later.

More particularly, the mechanism 100 comprises, for the display of a quantity, at least one display which comprises a roller 1, 1A, 1B, 2, 3, 3A, 3B, 4, and/or a combined roller 10.

Such a combined roller 10 comprises at least two rollers 1A, 1B, 3A, 3B, which are inside one another, the roller which is outer 1A, 3A, comprising at least one roller window 1C, 3C, which is arranged to allow vision or reading of the roller which is inside 1B, 3B. In the non-limiting variant illustrated, the rollers or combination rollers have numbers or the like with a height of 2.8 mm, which is compatible with six-position rollers with an outer diameter of 6.60 mm, or 6.00 mm for a inner roller in the case of a combined roller. This arrangement ensures readability and minimizes clutter.

The display of a digit requires ten positions, for example positions 0/1/2/3/4 on the inner roller, and positions 5/6/7/8/9 on the outer roller, i.e. five positions on each of the rolls.

More particularly, each roll 1, 1A, 1B, 2, 3, 3A, 3B, 4, or each combined roll 10 comprises at most six display positions, so as to ensure good readability for the user.

Thus, the outer roller can comprise a window instead of a display position, and the inner roller can advantageously comprise twice the zero position, according to the arrangement 0/1/2/3/4/0, which makes it possible to simplify the kinematics as will be seen later. The outer reel may have the arrangement 5/6/7/8/9/(), the latter symbol () corresponding to the window opening.

The figures 6 and 7 detail a non-limiting coding system used for the embodiment illustrated by the figures.

More particularly, the mechanism 100 is arranged to display the value of at least two magnitudes on at least two groups of displays 90M, 90H, coaxial and juxtaposed to each other. More particularly, at least one group of displays 90M, 90H, comprises at least one trigger or correction flip-flop 11, 12, 13, 14, 15, 16, which comprises a stop support finger 1390, which is arranged for, in certain relative angular positions, cooperating in abutment support with an abutment 528 that comprises a roller 1, 1A, 1B, 2, 3, 3A, 3B, 4, of a group of adjacent displays 90M, 90H, to block its rotation during certain display phases, and to synchronize the jump of the at least two groups of displays 90M, 90H.

The figures illustrate the mechanical digital display of hours and minutes.

The display of the minutes is made by a roller of minute units 1, juxtaposed with a roller of tens of minutes 2, in particular visible together through a window of minutes 5. The roller of minute units 1 is such a roller combined 10, and comprises an inner roller 1B, visible through the window 1C of the outer roller 1A, as visible on the picture 3 . These two rolls 1 and 2 form a first group of displays 90M which is the group of minutes displays.

The display of the hours is made by a roll of hour units 3, juxtaposed with a roll of tens of hours 4, in particular visible together through an hour window 6. The roll of hour units 3 is such a combined roller 10, and comprises an inner roller 3B, visible through the window 3C of the outer roller 3A. These two rollers 3 and 4 form a second group of displays 90H which is the group of hour displays.

The figure 1 illustrates a dial 7 carrying windows 5 and 6 for the minutes and hours, and surmounting a plate 8 which carries the rollers and the other constituents of the mechanism 100.

  dont les fonctions sont détaillées ci-dessous.

The figure 2 shows the different trigger and correction flip-flops which are, from left to right:

• the trigger rocker of the minutes units of the inner roller 11;
• the trigger rocker of the minutes units of the outer roller 12;
• the hour units correction flip-flop 15;
• the inner roll hour units trigger rocker 13;
• the outer roller hour units trigger flip-flop 14;
• the tens of hour correction rocker 16,
  whose functions are detailed below.

In a particular and non-limiting way, the rollers pivot around a common axis R; in a particular and non-limiting way, the rockers pivot around a common axis B.

The picture 3 represents a roller of minute units 1 according to the invention, which is a combined roller 10 which comprises, represented separately from left to right, an inner roller of minutes 1B, an outer roller of minutes 1A with its window of minutes 1C, and the assembly 1 consisting of this inner roller 1B mounted in this outer roller 1A. The roll of hour units 3 is similarly constructed, with an inner roll of hours 3B, an outer roll of hours 3A with its window 3C.

More particularly, at least one group of displays 90M, 90H comprises at least two rollers, one of which displays as a unit an integer multiple of the value of the unit of the other. More particularly still, each group of displays 90M, 90H comprises at least two rollers, one of which displays as a unit an integer multiple of the value of the unit of the other.

The display mechanism 100 then comprises, for at least one such group of displays 90M, 90H, at least one drive mechanism 50, for example in the illustrated embodiment a tens of minutes drive mechanism 50M, and a drive mechanism tens of hours 50H. The purpose of this drive mechanism 50 is to cause the roller of the multiple to rotate by one position when the roller of the sub-multiple has performed the rotation, or rotations, corresponding to all of its display sequences in the step of the multiple. Except in exceptional circumstances which will be detailed later, the rollers of the multiples (of the tens in the present embodiment) are therefore not driven by rockers, but by such a drive mechanism 50.

This drive mechanism 50, here a tens of minutes drive mechanism 50M, or a tens of hours drive mechanism 50H, is driven by the sub-multiple roller, here the units roller.

Thus each group of displays 90M, 90H comprises at least two rollers 1, 1A, 1B, 2, 3, 3A, 3B, 4, connected kinematically by such a drive mechanism 50, which comprises, in the in no way limiting version illustrated by the figures, a Maltese cross 53, 55, which is arranged to be driven in rotation by a pin 109, 319, fixed to the roller of the sub-multiple, and which is fixed in rotation to a star with lugs 51, 56, which is arranged to drive by one of its lugs 511, 561, a cloverleaf 52, 54, which the roller of the multiple carries, by radial grooves 529, 541. Here, the roller of the sub-multiple, that is- i.e. units, drives a Maltese cross in rotation, which drives a pin star which in turn drives the roll of the multiple, here tens. The rolls of minute 1 and hour 3 units thus carry pins 109, 319 respectively for this purpose, which are arranged to cooperate with radial grooves 531.551, which comprise Maltese crosses for minutes 53, or hours 55.

The figure 4 represents a tens of minutes roller 2, which laterally carries a tens of minutes cloverleaf 52, comprising six radial grooves 529, which are arranged to cooperate with a star stud 511 which comprises a stud star 51 coupled with a cross of Malta of minutes 53. This tens of minutes clover 52 carries a support lug 528, here in the form of a cubic block, which is arranged to serve as abutment support for a rocker limiting finger 1380 that comprises the rocker of triggering of the hours of the inner roller 13, as will be explained later.

More generally, the cloverleaf 52, 54, or the roll of the multiple, carries such a support lug which is arranged to serve as abutment support for a rocker limiting finger that includes a trigger rocker 11, 12 , 13, 14.

The lug star 51, 56 of the drive mechanism 50 of the upstream display 2 is advantageously arranged to drive in rotation, around an axis parallel to its own, a drive cloverleaf 57, which carries a stop pin of Rocker 579 arranged to serve as abutment support for a rocker abutment finger 1490 that includes a trigger rocker 11, 12, 13, 14.

The figure 5 represents a roll of the tens of hours 4, which similarly bears a trefoil 54, visible on the figure 45 , and whose shaft has a square drive 4160, and which laterally carries three tenons 72 or planet carrier pivots for a release mechanism 70 explained below. This disengagement mechanism 70 has the function of disengaging a drive mechanism 50, to allow the position correction of a roller 1, 1A, 1B, 2, 3, 3A, 3B, 4, directly by a correction rocker 15 , 16, and not by a drive mechanism 50.

The mechanism 100 advantageously comprises at least one combined roller 10, of which an inner roller 1B, 3B, is arranged to be driven in rotation by a rocker for triggering the inner roller 11, 13, and whose outer roller 1A, 3A, is arranged to be driven by a trigger rocker of the outer roller 12, 14, or by a first correction rocker 15. In particular, such a combined roller 10 is a sub-multiple roller.

The inner roller 1B, 3B, is again arranged to be driven in rotation by the first correction rocker 15, at certain predetermined instants and driven by a twenty-four-hour mobile 24 driven by the movement 500. This first rocker of correction 15 is juxtaposed with the release rocker of the inner roller 11, 13, and cooperates with it with the cams of the twenty-four-hour mobile 24. The first correction rocker 15 comprises a lateral prominence 151, which rests on a counterbore 135, of the trigger rocker of the inner roller 113. This prominence 151 rests on the counterbore 135, shortly before a jump controlled by a cam 21, 23, on which bears a feeler 2111, 2313, which comprises the rocker of triggering of the inner roller 11, 13. The correction latch 15 further comprises a drive finger 1501, which is arranged to take place next to a drive finger 1101, 1301, of the inner roller trigger latch. ieur 11, 13, and to cooperate with the same star 411, 413, of this inner roller 1B, 3B, so that, when the trigger rocker of the inner roller 11, 13 falls, at a controlled instant by the cam 21, 23, and for a jump authorized by the twenty-four-hour mobile 24, the first unit correction rocker hour 15 also falls to drive the star wheel 411, 413 in turn, thereby driving the inner roller 1B, 3B twice.

In general, each roller comprises a shaft, in particular carrying a square, capable of supporting a star for its rotational drive: one sees in particular in the figures the square 4120 for driving the roller 1, the square 4140 of the roller 3, and the square 4160 of roller 4. It should be noted that some rollers are not necessarily driven by rockers: this is the case here of the tens of minutes roller 2, which is driven by a drive mechanism tens of minutes 50M to Maltese cross.

The figure 6 represents a coding of the minutes display, according to which is constructed the particular, non-limiting, variant of the mechanism, which is illustrated by the figures, on the basis of the rollers of the figures 3 and 4 . In this particular case, in the combined rollers 10 as used for the display of the minute units 1 and the hour units 3, the inner roller 1B, respectively 3B, has six positions: 0, 1, 2, 3 , 4, 5, 0. The outer roller 1A, respectively 3A, has six positions: 5, 6, 7, 8, 9, (). The double parentheses or square brackets are used to code the opening that the considered roll has. This particular configuration makes it possible to have the largest digits in the minimum bulk, the same driving rocker stroke for the two rollers, and the same star-jumper assembly, as can be seen in the figures which include numerous components. identical elements.

• colonne 1 : valeur du rouleau des dizaines 2;
• colonne 2 : valeur du rouleau extérieur des unités 1A;
• colonne 3 : valeur du rouleau intérieur des unités 1B :
• colonne 4 : nombre de rotations du rouleau de la colonne 2;
• colonne 5 : nombre de rotations du rouleau de la colonne 3;
• colonne 6 : nombre de rotations du rouleau de la colonne 1.

The minute table of the figure 6 has six columns:

• column 1: value of the tens roll 2;
• column 2: value of the outer roll of the 1A units;
• column 3: value of the inner roll of the 1B units:
• column 4: number of rotations of the roller of column 2;
• column 5: number of rotations of the roller of column 3;
• column 6: number of rotations of the roller in column 1.

One line there corresponds to one minute.

The double parentheses or brackets correspond to the opening of the roll.

The table of the figure 6 only shows the display of the minutes "00" to "30", because we notice that there is a periodicity of ten minutes.

It is noted that, over a period of ten minutes, the inner roller 1B and the outer roller 1A each rotate six times.

More particularly, during the display of each unit position "5", the inner roller 1B also rotates so as to pre-position itself on the value "0" to be ready to display it during the next ten.

Therefore, the minute display requires a minute cam 21, and a ten minute cam 22.

• colonne 1 : valeur du rouleau des dizaines 4;
• colonne 2 : valeur du rouleau extérieur des unités 3A;
• colonne 3 : valeur du rouleau intérieur des unités 3B :
• colonne 4 : nombre de rotations du rouleau de la colonne 2;
• colonne 5 : nombre de rotations du rouleau de la colonne 3;
• colonne 6 : nombre de rotations du rouleau de la colonne 1 ;
• colonne 7 : nécessité d'une correction, notamment par une double rotation.

Similarly, the hour chart of the figure 7 has seven columns:

• column 1: value of the tens roll 4;
• column 2: value of the outer roll of the 3A units;
• column 3: inner roll value of 3B units:
• column 4: number of rotations of the roller of column 2;
• column 5: number of rotations of the roller of column 3;
• column 6: number of rotations of the roller of column 1;
• column 7: need for a correction, in particular by a double rotation.

One line corresponds to one hour.

The table of the figure 7 shows the hour display "00" to "24".

Note that column 4 and column 5 of this table of hours have a periodicity of twelve hours.

Column 7 shows that, when passing from position "23" to position "00", and when passing from position "00" to position "01", the inner roller 3B must rotate twice.

Column 6 shows that, during the passage at midnight, which does not fit into the general framework, the roller must be actuated by a particular mechanism.

Therefore, the hour display requires a 23-hour cam, and a twelve-hour cam (columns 4 and 5 of the table in the figure 7 ) which will be described here in the form of a first twelve-hour cam 244, corresponding to column 4 of the table of the figure 7 , and a second twelve-hour cam 245 corresponding to column 5 of the table of the figure 7 , a twenty-four hour cam 246 (column 6 of the table of the figure 7 ), and a correction cam 247 (column 7 of the table of figure 7 ) here comprising a notch 249. In the illustrated, non-limiting embodiment, a single twenty-four-hour mobile 24 groups the twelve-hour, twenty-four-hour, and correction cams, as seen on the figure 27 .

The reader may refer to these tables, for the understanding of certain particular display change configurations, which will be described below.

• le rouleau intérieur des minutes 1B est solidaire d'une étoile 411 maintenue par un sautoir 311 ;
• le rouleau extérieur des minutes 1A est solidaire d'une étoile 412 maintenue par un sautoir 312;
• le rouleau intérieur des heures 3B est solidaire d'une étoile 413 maintenue par un sautoir 313; on verra plus loin que cette même étoile 413 est agencée pour coopérer avec deux bascules à la fois, dont une bascule de déclenchement, et une bascule de correction pour certaines configurations de passage, ce qui explique sa double largeur;
• le rouleau extérieur des heures 3A est solidaire d'une étoile 414 maintenue par un sautoir 314;
• le rouleau des dizaines d'heures 4 est solidaire d'une étoile 416 maintenue par un sautoir 316, pour sa coopération avec une bascule de correction, que nécessite la problématique du passage à minuit dans ce type d'affichage particulier.

The figure 8 isolates the displays: in the right part a first group of displays which is the group of minutes 90M displays, and includes, from right to left, the roll of minute units 1 of the picture 3 , and the roll of the tens of minutes 2 of the figure 4 , and, in the left part, a second group of displays which is the group of hours displays 90H and comprises, from right to left, the roller of hour units 3, and the roller of tens of hours 4 of the figure 5 . These four rollers are here coaxial, with a common axis R, with rotating guide shafts 912 and 934, and some are connected to a drive starwheel held in the rest position by a jumper:

• the inner minutes roll 1B is secured to a star 411 held by a jumper 311;
• the outer minutes roll 1A is secured to a star 412 held by a jumper 312;
• the inner hour roller 3B is attached to a star 413 held by a jumper 313; we will see later that this same star 413 is arranged to cooperate with two flip-flops at the same time, including a trigger flip-flop, and a correction flip-flop for certain passage configurations, which explains its double width;
• the outer hour roller 3A is secured to a star 414 held by a jumper 314;
• the tens-of-hours roller 4 is secured to a star 416 held by a jumper 316, for its cooperation with a correction rocker, which the problem of the transition to midnight in this particular type of display requires.

The tens of minutes roller 2 is not connected to a star in the present application; however, a different coding of the rollers could require it, in which case its case is to be treated similarly to the tens of hours roller 4 for its cooperation with a correction flip-flop 16 presented later.

This tens of minutes 2 roller laterally carries a 52 trefoil for its drive by a Maltese cross 50M tens drive mechanism.

The tens-of-hours roller 4 laterally carries a trefoil 54 similar to that carried by the tens-of-minutes roller 2, and comprising radial grooves 541; this cloverleaf 54 is integral with a self-locking wheel 73 of a declutching mechanism 70, in the teeth of which planet wheels 71 mounted loosely on the tenons or planet carrier pivots 72 of the figure 5 , to cause the rotation of this roller for tens of hours 4 by clutching this self-locking wheel 73, while the disengagement of the satellites 71 causes the clutch to be disengaged.

The unit rollers 1, 3, carry pins 109, 319, which are arranged to cooperate with Maltese crosses of minutes 53, 55, for driving the tens rollers 2, 4, during most passages , apart from special passages at certain times, which will all be detailed later.

The figures 9 to 30 expose the passage of minutes. It shows the operation of the minute trigger rocker 11, pivoting about a rocker axis B, for controlling the inner roller 1B of the combined roller of the minute units 1. This rocker 11 is subjected to the action of a return spring 119, which tends to press a drive finger 1101, which rocker 11 comprises, on a star 411 which this inner roller 1B comprises, and which is itself subjected to the return torque of a jumper 311 for holding it in the rest position. Rocker 11 carries, between its pivot and its distal drive finger 1101, on the one hand a ten-minute feeler finger 2211, which is arranged to cooperate in support with a ten-minute cam 22 which is a cam with a straight edge slot type, and on the other hand a minute feeler roller 2111, which is arranged to rest on the substantially helical track of a minute cam 21, visible on the figure 15 . This substantially helical track makes it possible to raise the feeler of each rocker which follows this cam, before its jump. The feeler is in particular a ruby or similar roller, to reduce friction.

This minutes cam 21 includes a device to avoid any recoil at the moment of the jump when the feeler roller 2111 leaves the high point of the cam 21, which is its position on the figure 9 . The figure 16 illustrates this device: the cam 21 itself pivots on a cam base 210, a pin 212 secured to the cam 21 slides in a bean-shaped groove 211, which limits the stroke. Thus, during the fall, the pin 212 and therefore the cam 21 is ejected tangentially a little further into the groove 211, and drops the rocker 11, and any parasitic backward movement is avoided.

The figure 10 illustrates the passage of the minute unit, when the ten-minute feeler finger 2211 is not stopped by the relief of the ten-minute cam 22, and just after the jump of the feeler roller 2111, when the fall of the rocker 11 has just driven star wheel 411 of roller 1B which has turned one position.

The figures 11 to 14 are details of the sequence of cooperation between on the one hand the drive finger 1101, which forms a movable assembly 80 pivotally mounted on a pivot 84 and which comprises an elastic blade 81 movable between two front 82 and rear 83 stops, and on the other hand the star 411 of roll 1B. In the rest position of the figure 11 , the elastic blade 81 bears against a first front stop 82 located on the star 411 side. first stop 82 and the finger begins to pivot, its blade 81 approaches the second rear stop 83. Upon contact between the blade 81 and the second stop 83, the star 411 pivots, and the rocker 11 accompanies the star 411 over approximately two thirds of its pitch before reaching its stop, which ensures the passage of the top of jumper 311.

During the ascent of the rocker 11, the finger 1101 is free, until the return of the blade 81 in support on the first limit stop 82; the blade 81 is weaker than the jumper 311 of the star 411, the blade 81 bends to pass the top of the star 411, which therefore cannot be driven again by the finger 1101.

The figure 18 shows that 21 minutes cam,
comprises a substantially helical track, wide enough to be traveled by both feeler rollers 2111 and 2112 that comprise two neighboring rockers 11 and 12.

The figure 17 shows, together, this minute trigger rocker for the control of the inner roller 11, juxtaposed with the minute trigger rocker for the control of the outer roller 12, the feeler rollers 2111 and 2112 of which thus run along this same helical track of the cam 21, and whose ten-minute feeler fingers 2211 and 2212 are both arranged to cooperate with the same ten-minute cam 22, which authorizes or prohibits the fall of the respective rocker 11 or 12.

The figure 19 represents the same set represented in the position it occupies a few seconds before the jump, in a display position "04" of the minutes, with reference to the table of the figure 6 , with the display of the unit of minutes "4", where the outer reel 1A presents its aperture 1C (column 2 of the table), while the inner reel 1B presents the number 4 (column 3 of the table); the mechanism is ready to move to a global display position "05" with a display of units "5", where the outer roller 1A shows the number 5 (column 2), while the inner roller 1B returns to a position where it presents the number 0 (column 3) and is thus ready to anticipate the transition to the following ten minutes where the inner roller 1B will present its number 0 in the window 1C of the outer roller 1A. We see that the two ten-minute feelers 2211 and 2212 are not hindered by the ten-minute cam 22, and the two rockers 11 and 12 can drop when the time comes, to proceed, in a synchronized manner, to the rotation of the two rollers , interior 1B and exterior 1A. The figure 20 is the situation after the jump, in a display configuration of the value "05" where neither of these two flip-flops 11 and 12 is stopped by the ten-minute cam 22.

The figure 21 represents the same set after the jump, in another display position, of the value "6", where the inner roller 1B has not rotated and has remained in its display position, because the rocker 11 corresponding to the display of the inner roller 1B is stopped by the ten-minute cam 22, its feeler finger 2211 being in abutment on the notch of the ten-minute cam 22, and therefore the inner roller 1B does not rotate, and only the rocker 12 relating to the outer roller 1A falls and rotates the latter.

The figures 22 and 23 illustrate the ten-minute drive mechanism 50M, the principle of which is also used for triggering the ten hours in the other group of hour displays 90H. This mechanism surrounds the group of displays 90M comprising the combined roller of the units of minutes 1, and the simple roller of the tens of minutes 2; this mechanism is mobile with an axis parallel to the common axis R to the shafts of the various rollers, and comprises, on the side of the combined roller of the minute units 1, a Maltese cross of the minutes 53, whose grooves 531 are arranged to cooperate with piece 109, visible on the figure 17 , that carries this roll 1, and, on the side of the roll of the tens of minutes 2, and fixed in rotation with this Maltese cross of the minutes 53, a star with lugs 51, the lugs 511 of which are arranged to cooperate with the grooves 529 of the cloverleaf of the tens of minutes 52 of the figure 4 .

The figures 24 and 25 illustrate the passage of a dozen. The figure 24 represents the same set, represented in the position it occupies a few seconds before the jump, in global display position "09" with a display position of the minute unit "9", where the outer roller 1A presents the number 9 (column 2), while the inner roll 1B has the number 0 (column 3); the mechanism is ready to move to a global display position "10", where the tens roller, hitherto in display position "0", will move to position "1" (column 1), while , at the level of the combined roller of units 1, the outer roller 1A will present its aperture 1C (column 2) through which the inner roller 1B will continue, without rotation, to present the display "0" (column 3); a groove 531 of the Maltese cross of the minutes 53 of the units of minutes cooperates with the piece 109 of the reel of the units 1. The figure 25 represents the same set after the jump, in a global display configuration "10" where neither of the two flip-flops 11, 12 is stopped by the ten-minute cam 22; the outer reel 1A of the combined reel of 1 minute units rotated, and its 109 peg caused the 53 minute Maltese cross to rotate, which at the other end caused the ten minute clover to rotate 52 , and therefore of the ten-minute roll 2.

The display and passage of the hours is done in a similar way. The group of 90H hour displays has a display roller of 3 hour units, and a display roller of tens of hours 4. A drive mechanism of the tens of hours 50H surrounds this group of 90H displays, as with minutes, and works similarly to minutes; a rocker for triggering the hours of the inner roller 13 and a rocker for triggering the hours of the outer roller 14 are also juxtaposed, and are arranged to cooperate with a single hour cam 23, and with a combined twenty-four-hour wheel set 24, which comprises in particular a twenty-four hour cam and a twelve hour cam. The operation of the passage of hours is similar to the passage of minutes described above, the only significant variant being the presence of a twelve-hour cam, instead of a ten-minute cam. It is understood that the invention can be used for any combination of displays, one of which displays a multiple of the other, and for any display range. Of course, coding of the various rollers, and the nature of the cams and of the correction rockers, are to be adapted to each specific case. For example, the reels can occupy four, or six, or ten, or even twelve positions, and the multiplier coefficient between two reels of the same group of displays can also be four, or six, or ten, twelve positions, or other, for other displays such as calendar, moon phases, tides, or other. Thus, depending on the configuration of the rollers, the drive mechanism 50 can also generate the drive of the multiple roller with coefficients different from ten, for example four, six, twelve, or other.

More specifically, the twenty-four-hour mobile 24 here groups together a first twelve-hour cam 244 of the trigger rocker of the inner hour roller 13, a second twelve-hour cam 245 of the trigger rocker of the outer roller of hours 14 , and a twenty-four hour cam 246, and a correction cam 247, for the management of certain time passages: midnight, one o'clock in the morning, and in particular to guarantee the passage from the display "4" to the display “0”. This correction cam cooperates with correction flip-flops 15 and 16 detailed below.

The invention requires the presence of a synchronization mechanism between the display of the minutes and that of the hours, in particular at current times, that is to say other than at midnight.

The mechanical system transmits the instantaneousness of the jump from the units roller to the tens roller, both for the hours and for the minutes, thanks to the respective tens drive mechanism by Maltese cross, trefoil with lugs, and trefoil of coaching.

The synchronization of the hour unit jump with the ten minutes is necessary, since, when "59" is displayed on the minutes display 90M, it is necessary that, when passing from position "59" to the “00” position, the roll of hour units 3 also rotates synchronously.

The 13 hour units inner roller trigger rocker and the 14 hour units outer roller trigger rocker driving the two hour units rollers 3B and 3A drop a few minutes before the hour passes on lugs to stand on hold.

The figure 28 thus represents, a few minutes before a time change, the triggering rocker of the inner roller of hour units 13, which is similar to the trigger rocker of the inner roller of the minute units 11, and whose feeler finger 2313 has just left the cam of the hours 23. This trigger rocker of the inner roller of the hour units 13 comprises a second finger of rocker limitation 1380, which is arranged to cooperate in abutment abutment with a lug 528 that includes the cloverleaf 52 of the tens-of-minutes roller 2, which prevents the fall of the trigger rocker of the inner hour units roller 13 as long as that the tens of minutes roller 2 has not completed its rotation.

Similarly, the figure 29 represents, at the same time as the figure 28 , the same mechanism, of which the trigger rocker of the inner roller of the hour units 13 is not represented, in order to allow the vision of the trigger rocker of the outer roller of the hour units 14, whose feeler finger 2314 also just left the 23 hour cam; this release rocker of the outer roll of the hour units 14 also comprises a second rocker abutment finger 1490, which is arranged to cooperate in abutment support with a lug 579 that comprises a drive cloverleaf 57, kinematically linked to the system Maltese cross of minutes, and which, in the same way, prevents the fall of the rocker for triggering the outer roller of 14 hour units as long as the Maltese cross of minutes 53 has not completed its rotation. The driving trefoil 57 is in particular rotatably mounted on a shaft parallel to that of the Maltese cross of minutes 53, as visible on the figure 29 .

When the tens of minutes roller 2 rotates to pass from the display position "5" to the display position "0", the two lugs 528 and 579 leave the path of the respective flip-flops 13 and 14, which can then fall . The figure 30 shows these two rockers 13 and 14, just after the rotation of the tens of minutes roller 2 between its position "5" and its position "0", the fall of the rockers allowing the drive of the roller of the hours units 3.

The figure 31 shows the entire mechanism relating to the hours, which incorporates a 15-hour units correction rocker which is juxtaposed with the trigger rocker of the hour units inner roller 13, and a tens-of-hours correction rocker 16 which is juxtaposed with the trigger rocker of the outer roller of the hour units 14; the assembly is shown in position at 11:59 p.m. This figure also shows the two tens drive mechanisms. The table of the figure 7 shows that the passage of tens of hours, in particular from position "23" to position "00", does not follow the classic pattern of passages from "03" to "04" and from "13" to "14", because if the 'we followed the same logic, changing the display would change from "23" to "24" when we want to display "00" permanently, and not "24", for displays in the first hour of the morning ; this does not exclude a variant with a very brief transitional display “24” “00”, between the normal displays “23” “59” and “00” “00”, which each remain visible for approximately one minute.

To pass from the display "23" to the display "00", it is therefore generally necessary to pass the inner roll 3B of the hour units from position "3" to position "4" then to the position "0", do not rotate the outer roll 3A of the units of hours, and move the roll of the tens of hours 4 from position "2" to position "0" without rotating the Maltese cross of the hours 55 of the tens of hour drive mechanism.

The figures 32 and 33 represent the hour units correction rocker 15, which comprises a lateral prominence 151, which rests on a counterbore 135 of the trigger rocker of the inner hour units roller 13, the prominence 151 rests on the counterbore 135 a few minutes before the jump, she is then on standby. The hour units correction latch 15 comprises a drive finger 1501, which is arranged to take place next to the drive finger 1301 of the trigger latch of the inner hour units roller 13, and to cooperate with a same drive star 413 of the inner roll of the hour units 3B. When the 13 hour units inner roller trigger flip-flop drops at midnight, this 15 hour units correction flip-flop also drops when passing midnight, driving the 3B hour inner roller twice , and to allow the passage from the display "3" to the display "0", without going through the display "4"; it is the same at one o'clock in the morning, as visible on the board of the figure 7 .

The figure 34 represents, together, the hour units correction flip-flop 15, and the tens-hour correction flip-flop 16, which constitute an arrangement allowing, at midnight, the passage from the display "2" to the display " 0”, without the entry into function of the tens drive mechanism by the Maltese cross 55. This tens correction rocker at hour 16 falls a few minutes before midnight, and relies on the units correction rocker hour 15, via a synchronizer which is a shaft 17 carried by the tens of hour correction flip-flop 16, which is parallel to the pivot axis B common to the flip-flops, and of which a bearing surface 172 cooperates with a face d press 152 of the hour units correction rocker 15. This figure 34 shows, again, the feeler fingers 2415 and 2416 of these two rockers 15 and 16, which are both arranged to cooperate with the twenty-four-hour mobile 24 which authorizes or prohibits the fall of these rockers.

To allow the direct passage of an inner roller 1B, 3B, with a jump of two positions without rotation of the corresponding outer roller 1A, 3A, a correction rocker 15 carries a pivoting hook 154, which cooperates with a hook actuator 138 carried by the trigger rocker 11, 13, driving this inner roller 1B, 3B, so that, at the end of the travel of the trigger rocker 13, its hook actuator 138 releases the hook 154, and authorizes the fall of the correction rocker 15, which is released by the twenty-four-hour mobile 24, for driving the inner roller 1B, 3B.

The passage from position "3" to position "4" then to position "0" of the inner roller 3B of the hour units display requires a particular arrangement, visible on the figures 35 to 39 . The passage from position "3" to position "4" is done as at the passage of each hour, but, when the trigger rocker for the inner roller of hours 13 reaches the end of its travel, it pushes a pivoting hook 154, which is pivotally mounted on a pivot 153 secured to a fixed element such as a plate or the like, and which releases the hour units correction rocker 15, to actuate the same star 413 a second time, and thus pass from position "4" to position "0".

The figure 35 represents, together and juxtaposed, the trigger rocker for the inner hour roll 13, and the hour units correction rocker 15, the combination of which authorizes particular display passages, including the direct passage of the inner hour roller 3B from position "3" to position "0" without rotation of the outer roller 3A, and the passage of the tens of hours roller from position "2" to position "0" without rotating the Maltese cross of 55 hours of the tens drive mechanism. To allow the direct passage of the inner hour roller 3B from position "3", via position "4" to position "0" without rotation of the outer roller 3A, the hour units correction rocker 15 carries a hook swivel 154, which cooperates with a hook actuator 138 carried by the trigger rocker for the inner hour roller 13. This figure shows, juxtaposed, the drive fingers 1301 and 1501 of these two rockers 13 and 15, which are arranged to cooperate with a same drive star 413 of the inner roll of hour units. The hour units correction flip-flop 15 includes a feeler finger 2415, which is arranged to cooperate with the combined twenty-four-hour mobile 24, and in particular with its outer track; the transition from position "3" to position "4" is conventionally controlled by the drive finger 1301 of the trigger rocker for the inner hour roller 13 while the hour unit correction rocker 15 is immobilized by this hook 154.

And, at the end of the travel of the trigger rocker for the inner roll of hours 13, its hook actuator 138 releases the hook 154, and authorizes the fall of the correction rocker of hour units 15, released by the mobile of twenty-four hours 24, and whose drive finger 1501 controls a new rotation of the star 413 of the inner hour roller 3B for the display of the "0" position.

The hook actuator 138 is arranged to push an oblique track 158 of the pivoting hook 154. The rocker 15 carries a pin support finger 152 which carries a locking pin 156, which cooperates with a cylindrical track 155 of the hook 154 during a game of the angular stroke of the latter, and which escapes it at the end of the angular stroke of the hook under the thrust of the hook actuator 138. On the figure 37 , the hook actuator 138 bears against the oblique track 158 of the hook 154, and neither of the two rockers 13 and 15 has pivoted. The figure 38 illustrates the beginning of the drop of the trigger rocker for the inner roll of hours 13, for the passage from position “3” to position “4”; the hook actuator 138 pushes back the oblique track 158, and causes the hook 154 to pivot, which again cooperates with its pin 156 at the level of its concentric cylindrical track 155, immobilizing the hour units correction rocker 15. The figure 39 illustrates the end of the drop of the trigger rocker for the inner roll of hours 13 for the passage from position "3" to position "4"; the hook actuator 138 pushes back the oblique track 158 of the hook 154, and causes the hook 154 to pivot, which escapes its pin 156, releasing the hour units correction rocker 15, which, also released by the twenty -four hours 24, can pivot and drive the roller by its drive finger 1501 interior of the hour units 3B, which has just passed briefly into position "4" under the action of the fall of the trigger rocker for the interior roll of the hours 13, towards the "0"position; the twenty-four-hour mobile 24 is arranged to allow the fall of the hour unit correction flip-flop 15 only twice a day, at midnight and at one o'clock in the morning. 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 rocker 15 remains on the upper part of the twenty-four hour cam 247, which prevents it from falling and prevents it from rotating the star wheel 413 of the inner roller 3B units of hour.

The passage of the tens of hours roller 4 from position "2" to position "0" requires the intervention of the tens of hours correction rocker 16, already presented on the figure 34 . As seen on the figure 41 , the tens of hour correction flip-flop 16 cooperates with a twenty-four-hour cam 246, located on the twenty-four-hour mobile 24, in order, each day at midnight, to release this flip-flop 16 to drive a linked star 416 to the tens of hours roller 4, to move it from position "2" to position "0". But then it is necessary to short-circuit the tens drive mechanism comprising the Maltese cross of the 55 hours, because at midnight the outer roller 3A of the hour units blocks the rotation, because the mechanism is in the situation of the figure 42 , in a blocking position at midnight, which requires the installation of a release mechanism 70.

A particular variant of this release mechanism 70 is partially visible on the figure 41 , and illustrated in detail by the figures 43 to 47 ; this release mechanism 70 comprises a self-locking wheel 73 with satellites 71, similar to that of an automatic reverser, to allow the rotation of the tens-of-hour roller 4 independently with respect to the drive clover linked to the 55-hour Maltese cross of the tens drive mechanism, which itself is blocked. The figure 43 shows the trefoil 54 of the tens of hours roller 4, under which trefoil 54 we see this self-locking wheel 73 cooperating with satellites 71, in particular and not limited to three satellites 71 which pivot on three tenons or pivots 72 carried by the tens roller of 4 hours.

The figure 45 illustrates a classic ten passage. When the outer roller 3A of the hour units moves from position "9" to position "0", it activates the Maltese cross at 55 hours, which rotates the trefoil 54 integral with the self-locking wheel 73; the satellites 71 have a particular non-reversible shape, and lock in the teeth of the self-locking wheel 73, which causes the rotation of the roller for tens of hours 4; the self-locking wheel 73 and the tens roller 4 rotate clockwise as seen in the figure, and at least one satellite 71 is braced with the teeth of the self-locking wheel 73.

The transition from position "23""59" to position "00""00" is illustrated by the figures 46 and 47 : the fall of the rocker on the star 416 of the tens of hours roller 4 causes the latter to rotate, also in the clockwise direction of the figure; satellites 71 can then turn freely around the self-locking wheel thanks to the shape of their teeth. More particularly, an angular offset between the satellites is imposed to reduce the blind spot.

Naturally the release mechanism 70 can take other constructive forms, for example with a mechanism of the freewheel type, authorizing rotation in one direction, and imposing in the other direction a clutch by blocking a ball on the wall of a chamber in which this marble is enclosed, or whatever.

Certain alternatives of this disengagement mechanism 70 may thus comprise two inputs.

The jumping roller clockwork display mechanism 100 according to the invention makes it possible to have, under a small volume, an original display, which can constitute a main display or a secondary display, alone, or in combination or juxtaposition with other displays.

A particular application describes below 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 concerns a space mission to the planet Mars: one of the displays is that linked to the planet Earth and to the duration of terrestrial days and hours, while the other display, made with a clockwork display mechanism jumping roller 100 according to the invention, is linked to the planet Mars, and to the duration of Martian days and hours. In this particular case, the duration of a Martian solar day is 24.659790 Earth hours (close to 24 hours and 40 Earth minutes). The ratio between the duration of an Earth day and a Martian day is therefore equal to 24/24.659790 = 0.973244296089269.

A suitable timer, which uses mobiles with reasonable numbers of teeth for use in a watch, has a 22-tooth earth roadway, which completes one revolution, when a 36-tooth timer pinion completes 0.6111 revolutions, and a 43-tooth timer wheel, which cooperates with a 27-tooth Martian roadway, which then performs 0.973251028806584 revolutions. The error related to this timer is small, about 6.733. 10 ^-6 , which corresponds to 4.10 ^-4 Earth minutes, or 0.02424 Earth seconds, or 0.58171 second per Earth day.

We therefore have an advance of about 0.58 seconds per day: when the Martian time display changes from 11:59 p.m. to 12:00 a.m., the change occurs 0.58 seconds before the planet Mars has actually finished its rotation on itself.

Of course, other gear ratios make it possible to achieve a lower error: a 19-tooth earth roadway, which performs one revolution, when a 12-tooth timer pinion performs 1.583333 revolutions, as well as a 67-tooth timer wheel , which cooperates with a Martian roadway of 109 teeth, which then performs 0.973241590214067 revolutions. The error associated with this timer is then approximately minus 0.23 seconds per day, but at the cost of cogs with a large number of teeth, which would require a much greater volume.

The timer mechanism with an advance of about 0.58 seconds per day therefore remains a good solution for a watch, we note that this error is much lower than the rate error of many usual watchmaking regulating organs.
