Description

Technical Field

[0001] The present invention relates to a display for displaying an indication derived from time or time. The present invention also relates to a jumper or a dividing device. The present invention also relates to a timepiece movement including this type of display device and / or this type of jumper or dividing device. The present invention further relates to a timepiece including this type of display device and / or this type of jumper or dividing device, or this type of timepiece movement. Finally, the present invention relates to an operating method for this type of display device or this type of timepiece movement or this type of timepiece.

Background Art

[0002] The prior art "Grande Date" mechanism systematically employs a 31-tooth command gear or disk, or a command gear or disk that provides a full rotation in 31 steps, which is bulky and makes it difficult to introduce this type of mechanism into a timepiece movement. Furthermore, the sequencing of the command devices that drive the tens and units disks is often complex, reducing the freedom of choice for positioning each mobile unit in the plane.

[0003] All the solutions identified employ either a 31-tooth command mobile unit or disk. By way of example, Patent Document 1 and Patent Document 2 disclose two main drive concepts, currently known as the "Grande Date" mechanism.

[0004] Patent Document 1 discloses an array of a first command mobile unit that drives a first display mobile unit for the units digit and a second display mobile unit for the tens digit. The two display mobile units are arranged side by side. The command mobile advances one step every 24 hours, achieving a full rotation in 31 steps. The command mobile includes three sets of teeth, distributed to three different heights. The first set of teeth is provided to drive itself, the second set of teeth, containing 30 teeth, is provided to drive the units digit display mobile unit, and the third set of teeth, containing 4 teeth, is provided to drive the tens digit display mobile unit. The arrangement to three different heights and the use of a command mobile unit that sequences the jumps over 31 steps make the solution particularly bulky and difficult to implement in a watch movement.

[0005] Patent Document 2 discloses the use of a command disc that advances one step every 24 hours, driving a first display mobile unit for the units digit and a second display mobile unit for the tens digit. These two display mobile units are arranged side by side. The command disc includes two sets of teeth, arranged at two separate heights. The first set of teeth includes 31 teeth, of which 30 function to drive the units digit display mobile unit. The second set of teeth includes 31 teeth, of which 4 function to drive the tens digit mobile unit. The overall dimensions of this type of disc in plane are very large. This is similar to a date disc, which gives virtually no flexibility in the arrangement of the two display mobile units in a watch movement. Furthermore, the adoption of a disc that orders jumps over 31 steps makes the introduction of this solution into a watch movement particularly difficult.

[0006] As described above, the "Grande Date" mechanism typically includes two date display mobiles: a first that displays the units digit and a second that displays the tens digit. Each of these two display mobiles requires an angular position indexing device that allows for the indexing of the units and tens digits within a window, respectively. The "indexing" of the mobiles preferably means maintaining the mobile at a specific angular position from a finite number of angular positions of the mobile, where these positions are separated from each other by angles, and in particular by fixed angles.

[0007] The problem with this type of "grande-date" mechanism is that when changing the date, the movement's energy consumption depends particularly on the date being changed. In fact, according to the ordering of the date display mechanism, it is necessary to drive one or more "grande-date" display mobiles. With conventional mobile indexing devices, the movement must overcome one or two jumpers or levers, each constituting the indexing device, which generates energy consumption that tends to vary depending on the date being changed. When the movement must overcome two jumpers or levers, the regulating unit has less energy available and can therefore generate amplitude loss at that same regulating unit height. Such amplitude changes must be minimized as much as possible to obtain the most optimized timekeeping performance.

[0008] The various prior art documents identified employ two levers incompatible with the "Grande Date" mechanism and / or do not offer any solutions for having equal or substantially equal energy consumption whether there is one or more indexing levers being actuated.

[0009] Patent Document 3 discloses a calendar including a date indicator and a day of the week indicator. These mobile indexing devices include a lever having two beaks fixed to each other for positioning the two indicators, an elastic return element, and an eccentric fixed to the lever. The eccentric allows adjustment of the relative position of the two beaks, thereby allowing adjustment of the angular indexing positions of the two indicators. Since degrees of freedom are required between the two beaks for them to function independently of each other, this solution cannot be employed for indexing in a "grande-date" mechanism.

[0010] Patent Document 4 discloses a calendar including a mobile indexing device for positioning date and day-of-the-week indicators, comprising a single lever having two beaks and two elastic return elements. To give the indexing device an additional degree of freedom, the lever further includes a slot adapted to cooperate with a pin fixed to the frame of the movement, forming a sliding connection. Although the beaks are fixed to only a single lever, this additional degree of freedom allows the indicators to function independently of each other. In fact, thanks to this sliding connection, if only one of the two indicators is activated during a first operation to adjust the calendar, for example, the beak cooperating with the other indicator is held in the teeth of the indicator and acts as a pivot for the lever. In this case, only one of the two elastic return elements is loaded. The operation is similar if the other indicator is activated during a second operation to adjust the calendar, for example. On the other hand, if both indicators are activated simultaneously during a conventional operation of the calendar, the lever pivots around the pin and both elastic return elements are loaded. The indexing device does not provide any solution to enable the operation of the same return element when two indicators are activated simultaneously. Furthermore, the indexing device does not enable equal or substantially equal energy consumption regardless of the number of indicator mobiles activated.

[0011] Patent Document 5 discloses a calendar including a mobile indexing device that includes a lever having two beaks that can operate independently of each other. The mobile indexing device is described as including at least one beak intended to index a date indicator or a day of the week indicator, and two directional elastic parts that enable the elastic return of the device. In this type of device, the equipment of the elastic parts of the mobile indexing device, and the resulting energy consumption, depends on the number of beaks that are operated. For this reason, this solution is not an optimal solution. [Prior art documents] [Patent Documents]

[0055] A first embodiment of the clock 120 will be described below with reference to Figures 1 to 8.

[0056] Clock 120 is, for example, a small clock, especially a wristwatch.

[0057] The watch 120 includes a watch movement 110. The watch movement is intended to be housed within the watch case to protect itself from the external environment.

[0058] The watch movement 110 may be an electronic movement, a mechanical movement, or especially an automatic movement.

[0059] The clock movement includes a device 100 that displays an indicator of time or time-derived indication. The indicator of time or time-derived indication is preferably a date indicator. However, the indicator may be of other types, particularly two-digit or more numerical indicators such as a year indicator, a month indicator, a week indicator, an hour indicator, a minute indicator, or a second indicator.

[0060] In this first embodiment, the display device is, for example, a device that displays a date of the "Grande Date" type.

[0061] The device 100 that displays an indication of time or time derived from time, - A first display mobile unit 10 including a first set of teeth 11b, a second set of teeth 11c, and a first disk 12 having a digit 13 intended to display the units digit of an indication of time or time-derived indication, - A second display mobile unit 20 including a third set of teeth 21b, a fourth set of teeth 21c, and a second disk 22 having a digit 23 intended to display the tens digit of an indication of time or time-derived indication, - Mechanism 90 for driving the first and second mobile units, Includes.

[0062] The drive mechanism 90 is - A first command mobile unit 30 including a fifth dentition 30a adapted to cooperate with the first and third dentitions, particularly in occlusion, - A second command mobile unit 40, including a sixth dentition 40a adapted to cooperate with the second and fourth dentitions, particularly in occlusion, Includes.

[0063] The first display mobile unit 10 pivots around the first axis A1. The second display mobile unit 20 pivots around the second axis A2. The first and second axes are preferably parallel or substantially parallel. The first and second mobile units are preferably arranged side by side such that the ones digit of the first mobile unit and the tens digit of the second mobile unit are located close to each other to display a value or information, such as the date value for the month. The device may include markers such as windows provided on the dial or plates of opposite colors to the respective digits 13 and 23 on the discs 12 and 22, which allow for the indication or definition of an information reading area.

[0064] The display device 100 further includes an angular position indexing system 80 for the first and second display mobile units. This system includes arms 81 and 82, respectively, adapted to angularly index the first and second display mobile units, as described below.

[0065] The first display mobile unit 10 includes a first gear 11, which in particular includes a first tooth row 11b and a second tooth row 11c. The first tooth row has, for example, nine teeth. The first tooth row is, for example, a set of ten teeth distributed equiangled around axis A1, with one of the ten teeth removed or not formed. In other words, the first tooth row is a set of ten teeth with one tooth missing from the original ten. The second tooth row 11c has, for example, two teeth. The second tooth row is, for example, a set of ten teeth distributed equiangled around axis A1, with eight of the ten teeth removed or not formed. In other words, the second tooth row is a set of ten teeth with eight teeth missing from the original ten. The two teeth of the second dental arch are preferably juxtaposed, i.e., there is no space between the two teeth of the second dental arch that is left by the missing tooth. These configurations of missing teeth in the dental arches are adapted to give a specific sequence to the driving of the second mobile unit as well as the first mobile unit, as described below. The first and second dental arches may appear to constitute a single dental arch without missing teeth, such that one tooth in the first dental arch is at the angular position of the missing tooth in the second dental arch, and one tooth in the second dental arch is at the angular position of the missing tooth in the first dental arch. Furthermore, at least one tooth in the first dental arch may similarly be juxtaposed with a tooth in the second dental arch.

[0066] The first disk 12 contains the ten units digits from 0 to 9. These digits are represented on the units digit display disk 12.

[0067] The first tooth row 11b and the second tooth row 11c are juxtaposed at two separate heights, distributed across planes P1 and P2, respectively, as shown in Figure 3. Planes P1 and P2 are parallel to each other and distinct from each other. The planes are preferably perpendicular to axis A1. Thus, plane P1 intersects with the first tooth row but not with the second tooth row. Similarly, plane P2 intersects with the second tooth row but not with the first tooth row.

[0068] The first and second tooth rows are fixedly attached to each other in rotation around axis A1. Therefore, one tooth row cannot rotate by a predetermined angle around axis A1 unless the other tooth row rotates by the same predetermined angle. For example, the first and second tooth rows are fixed to each other or connected by an internal connection. Alternatively, the first and second tooth rows are manufactured as a single unit or as a single block or element.

[0069] The second display mobile unit 20 includes a second gear 21, which in particular includes a third tooth row 21b and a fourth tooth row 21c. The third tooth row has, for example, four teeth. The third tooth row is, for example, a set of 10 teeth distributed equiangled around axis A2, with 6 of the 10 teeth removed or not formed. In other words, the third tooth row is a set of 10 teeth with 6 teeth missing from the original 10. The 4 teeth of the third tooth row are preferably distributed as follows: two juxtaposed teeth, the space left by the 2 missing teeth, one tooth, the space left by the 2 missing teeth, one tooth, the space left by the 2 missing teeth.

[0070] The fourth dental arch 21c has, for example, six teeth. The fourth dental arch is, for example, a set of ten teeth distributed equiangled around axis A2, with four of the ten teeth removed or not formed. In other words, the fourth dental arch is a set of ten teeth with four teeth missing from the original ten. The six teeth of the fourth dental arch are preferably distributed as follows: two adjacent teeth, the space left by one missing tooth, two adjacent teeth, the space left by one missing tooth, two adjacent teeth, the space left by two missing teeth. The third and fourth dental arches may appear to constitute a single dental arch with no missing teeth, such that one tooth in the third dental arch is at the angular position of a missing tooth in the fourth dental arch, and one tooth in the fourth dental arch is at the angular position of a missing tooth in the third dental arch. Furthermore, at least one tooth in the third dentition may similarly be positioned alongside a tooth in the fourth dentition.

[0071] These tooth-missing dentition configurations are adapted to give a specific sequence to the driving of the first mobile unit, as well as the second mobile unit, as described below. In particular, the second command mobile unit is also adapted to be driven by the first display mobile unit and / or the second display mobile unit.

[0072] The second disk 22 contains the ten tens digits from 0 to 3. These digits are represented on the tens digit display disk 22. The digits are represented in the order 0, 0, 1, 1, 1, 2, 2, 2, 3, 3.

[0073] The third and fourth tooth rows 21b and 21c are positioned side-by-side at two separate heights, respectively, on planes P1 and P2, as shown in Figure 3. Planes P1 and P2 are preferably perpendicular to axis A2. Therefore, plane P1 intersects with the third tooth row but not with the fourth tooth row. Similarly, plane P2 intersects with the fourth tooth row but not with the third tooth row.

[0074] The third and fourth tooth rows are fixedly attached to each other in rotation around axis A2. Therefore, one tooth row cannot rotate by a predetermined angle around axis A2 unless the other tooth row rotates by the same predetermined angle. For example, the third and fourth tooth rows are fixed to each other or connected by an internal connection. Alternatively, the third and fourth tooth rows are manufactured as a single unit or as a single block or element.

[0075] In addition to the first command mobile unit and the second command mobile unit, the drive mechanism 90 includes a drive gear 60, which includes a seventh tooth row 61 adapted to directly or indirectly drive the first command mobile unit.

[0076] In particular, the drive mechanism 90 may include an intermediate mobile unit 50 that cooperates with the seventh tooth row 61 of the drive gear 60 and the fifth tooth row of the first command mobile unit 30 due to interference, especially due to meshing. For this reason, the seventh tooth row 61 is adapted to indirectly drive the first command mobile unit (via the intermediate mobile unit 50).

[0077] The drive mechanism 90 may be of the instantaneous jump type, the semi-instantaneous jump type, or the drag type.

[0078] The drive mechanism 90 is configured and / or arranged to advance the first command mobile unit one step every 24 hours, i.e., to rotate the first display mobile unit one-tenth of a rotation every 24 hours.

[0079] As described above, the first command mobile unit 30 enables the driving of the first display mobile unit 10 and / or the second display mobile unit 20, more specifically the driving of the first tooth row 11b and / or the third tooth row 21b, via the fifth tooth row 30a.

[0080] As described above, the second command mobile unit 40 enables the driving of the first display mobile unit 10 and / or the second display mobile unit 20, more specifically the driving of the second gear row 11c and / or the fourth gear row 21c, via the sixth gear row 40a. Furthermore, the second command mobile unit is driven by the first display mobile unit and / or the second display mobile unit.

[0081] The first and second command mobile units 30 and 40 are, for example, coaxial with respect to a third axis A3. Axis A3 is preferably parallel to axes A1 and A2.

[0082] The fifth and sixth tooth rows 30a and 40a are positioned side by side at two separate heights, located in planes P1 and P2, respectively, as shown in Figure 4. Planes P1 and P2 are preferably perpendicular to axis A3. Therefore, plane P1 intersects with the fifth tooth row but not with the sixth tooth row. Similarly, plane P2 intersects with the sixth tooth row but not with the fifth tooth row.

[0083] The first and second command mobile units 30 and 40 are mounted so as to rotate freely relative to each other. In other words, the first and second command mobile units are freely rotatable relative to each other.

[0084] The fifth and sixth dental arches 30a and 40a each have, for example, 10 teeth. These dental arches may have different numbers of teeth. However, it is advantageous for the fifth and sixth dental arches 30a and 40a to have the same number of teeth.

[0085] The first and second tooth rows 11b and 21b, positioned at the height of the first plane P1, are respectively adapted to cooperate with the fifth tooth row 30a of the first command mobile unit 30, which is also positioned at the height of the first plane P1. More specifically, the fifth tooth row 30a of the first command mobile unit 30 is driven one step every 24 hours.

[0086] The two display mobile units 10 and 20 are also arranged at the height of the second plane P2 and driven by the sixth tooth row 40a of the second command mobile unit 40, which is adapted to cooperate with the tooth rows 11c and 21c. Depending on the date jump sequence, the second command mobile unit 40 can drive or be driven by the tooth rows 11c and 21c.

[0087] More specifically, using the tooth row 50a as a means, the drive mechanism 90 drives the fifth tooth row 30a of the first command mobile unit 30 by one step per day, and similarly, depending on the date, drives the first display mobile unit 10 and / or the second display mobile unit 20 via their respective tooth rows 11b, 21b. Depending on the date, the tooth row 40a of the second command mobile unit 40 may be driven by the first display mobile unit 10, more specifically by tooth row 11c, and / or by the second display mobile unit 20, more specifically by tooth row 21c. Once driven, the second command mobile unit 40 can similarly drive the first display mobile unit 10 via tooth row 11c and / or the second display mobile unit 20 via tooth row 21c.

[0088] In the second modified example of the first embodiment shown in Figure 6, only the configuration of the second display mobile unit 20 is changed. In this modified example, the second display mobile unit 20 includes a third tooth row 21b having seven teeth and positioned in plane P1, and a fourth tooth row 21c having eight teeth and positioned in plane P2.

[0089] The third dentition is, for example, a set of 10 teeth distributed equiangled around axis A2, with 3 of the 10 teeth removed or not formed. In other words, the third dentition is a set of 10 teeth with 3 teeth missing from the original 10. The 7 teeth of the third dentition are preferably distributed as follows: 3 jutting teeth, the space left by 1 missing tooth, 2 jutting teeth, the space left by 1 missing tooth, 2 jutting teeth, the space left by 1 missing tooth.

[0090] The fourth dental arch is, for example, a set of 10 teeth distributed equiangled around axis A2, with 2 of the 10 teeth removed or not formed. In other words, the fourth dental arch is a set of 10 teeth with 2 teeth missing from the original 10. The 8 teeth of the fourth dental arch are preferably distributed as follows: 8 juxtaposed teeth and the space left by the 2 missing teeth.

[0091] This modification has the advantage of providing tooth rows 21b and 21c with fewer missing, removed, or not formed teeth, which can prevent distortion of arms 81 and 82, and more specifically of arm 82 in cooperation with the second mobile unit.

[0092] A second embodiment of the clock 120 will be described below with reference to Figure 9.

[0093] Clock 120 is, for example, a small clock, especially a wristwatch.

[0094] The watch 120 includes a watch movement 110. The watch movement is intended to be housed within the watch case to protect itself from the external environment.

[0095] The watch movement 110 may be an electronic movement, a mechanical movement, or especially an automatic movement.

[0096] The clock movement includes a device 100 that displays an indicator of time or time-derived indication. The indicator of time or time-derived indication is preferably a date indicator. However, the indicator may be of other types, in particular a two-digit or more numerical indicator such as a year indicator or a month indicator or an hour indicator or a minute indicator or a second indicator.

[0097] In this second embodiment, the display device is, for example, a "Grande Date" date display type display device.

[0098] In this second embodiment, the display device further includes a modification mobile unit 70 that acts on the intermediate mobile unit 50, more specifically on the teeth row 50a. Alternatively, the modification may be achieved by directly driving the fifth teeth row 30a of the first command mobile unit 30. The device may further include an arm (replacing the modification mobile unit 70) used to act on the mobile unit 50 or the first command mobile unit 30 to achieve the modification.

[0099] Various design variations are possible to drive the two display discs 12 and 22. All variations described herein have the same number of teeth in the display mobile units 10 and 20 and the command mobile units 30 and 40, and function in the same order to display the date. The only difference among all variations described herein is the arrangement and number of teeth in the third and fourth tooth rows of the display mobile unit 20.

[0100] Regardless of the embodiment or modification, the first, third, and fifth tooth rows preferably have substantially the same first primitive diameter.

[0101] Regardless of the embodiment or modification, the second, fourth, and sixth tooth rows preferably have substantially the same second original diameter.

[0102] Regardless of the embodiment or modification, the first and second original diameters are preferably equal or substantially equal.

[0103] Regardless of the embodiment or modification, the first and second command mobile units 30 and 40 are preferably arranged coaxially. Nevertheless, it is also possible to arrange them on two separate axes while maintaining the same operation of the kinematic chain of the display device.

[0104] Regardless of the embodiment or modification, the first tooth row 11b, the second tooth row 11c, the third tooth row 21b, and the fourth tooth row 21c, together with the fifth tooth row 30a and the sixth tooth row 40a of the first and second command mobile units 30 and 40, preferably all have substantially identical contours and modules. These six tooth rows also have the same angular pitch for 10 teeth distributed equiangled around each axis, whether or not they are absent. However, these features do not constitute a limitation on the function of the device. For example, it is entirely possible to provide two display mobile units 10 and 20 with different numbers of teeth to advance different sequences of digits on the other two display discs 12 and 22. The number of digits on the two display mobile units 10 and 20 do not have to be the same. Similarly, the number of teeth on gears 11 and 21 do not have to be the same. The number of teeth on the two command mobile units 30 and 40 also does not affect the jump order of the device. The number of teeth in the fifth tooth row 30a of the first command mobile unit 30 may be different from the number of teeth in the sixth tooth row 40a of the second command mobile unit 40.

[0105] Regardless of the embodiment or modification, the number of locations where the teeth of the tooth rows 11b, 11c, 21b, and 21c of the two display mobile units 10 and 20 can be arranged may be a multiple of the number of digits shown on the display discs 12 and 22.

[0106] Regardless of the embodiment or modification, the meshing of the tooth rows 11b, 11c, 21b, and 21c of the two display mobile units 10 and 20 may similarly be achieved by different contours and / or modules of the tooth rows 30a and 40a of the two command mobile units 30 and 40. For example, tooth rows 30a and 40a may be substantially half the dimensions of tooth rows 11b, 11c, 21b, and 21c.

[0107] Other design variations may include two display discs 12 and 22 that are superimposed or partially superimposed. It is also possible to arrange the two display discs coaxially. In the case of coaxial superposition of the display discs, the structure of the kinematic chain must be transposed to four separate planes, rather than two, because the teeth 11b, 11c, 21b, and 21c of the two display mobile units 10 and 20 must be coaxial. However, the kinematic chain remains unchanged because it is still possible to obtain a fifth tooth 30a of the first command mobile unit 30 that meshes with the first and third tooth 11b and 21b, and a sixth tooth 40a of the second command mobile unit 40 that meshes with the second and fourth tooth 11c and 21c.

[0108] Regardless of the embodiment or modification, a locking system, particularly a "Maltese cross," may be added to one or more auxiliary heights of the display mobile units 10 and 20 or the command mobile units 30 and 40.

[0109] Regardless of the embodiment or modification, the first command mobile unit 30 may be driven directly by the intermediate mobile unit 50 via their respective tooth rows 30a and 50a, or by the auxiliary height of teeth (not shown).

[0110] Regardless of the embodiment or modification, it is possible to drive the first and second mobile units directly from the first command mobile unit 30 (without relying on mobile units 50 and 60). For this purpose, the first command mobile unit 30 may include a limited number of n teeth, for example, one tooth, two teeth, or three teeth (distributed equally angularly), and be configured such that a rotation of 1 / n revolution occurs every 24 hours. The drive may be of the instantaneous jump type, the semi-instantaneous jump type, or the drag type. For example, the mobile unit 30 may include only two diametrically opposed teeth that drive the first and second indicator mobile units 10 and 20 which are on the centerline. In this case, the command mobile unit must perform a half-rotation every 24 hours.

[0111] Regardless of the embodiment or modification, the representation of zeros in the digits on the tens digit display disk 22 may be replaced by gaps, i.e., by areas on the disk that do not contain digits. Thus, the order 0, 0, 1, 1, 1, 2, 2, 2, 3, 3 may be replaced by "gap", "gap", 1, 1, 1, 2, 2, 2, 3, 3.

[0112] Regardless of the embodiment or modification, the clock, specifically the movement or display device, may include a jumper or indexing device 80, and a first embodiment of the jumper or indexing device 80 described below with reference particularly to Figures 9 to 13.

[0113] The jumper or indexing device 80 is - A first arm 81 including a first beak 81a for positioning the first mobile unit 10, - At least one second arm 82 including a second beak 82a for positioning the second mobile unit 20, - An element 84 that elastically returns the first arm and the second arm to the positioning configuration of the first and second mobile units, On the one hand, there is an elastic return element, On the other hand, the first and second arms, - Lever 83 interacting between, Includes.

[0114] The jumper or indexing device 80 enables the indexing of the respective angular positions of the first and second mobile units, that is, the definition of specific angular positions within a certain number of stable angular positions, for example, 10 positions, for each of the first and second mobile units. These positions are the positions in which the mobile units can represent information.

[0115] As described above, the first mobile unit 10 is rotatable around axis A1, and the second mobile unit 20 is rotatable around axis A2. The device 80 preferably includes a frame 99 on which the first mobile unit 10 is mounted so as to be rotatable around axis A1, and the second mobile unit 20 is mounted so as to be rotatable around axis A2. The frame may be a movement blank, such as a plate or a calendar ring 99.

[0116] The first arm or lever 81 is mounted to pivot relative to the frame 99 around the pivot axis A5 of the first arm.

[0117] The second arm or lever 82 is mounted to pivot relative to the frame 99 around the pivot axis A5 of the second arm.

[0118] The first arm or lever 81, in particular its first beak 81a, is intended to cooperate with the first teeth 11b and second teeth 11c of the first gear 11 of the first display mobile unit 10. The second arm or lever 82, in particular its second beak 82a, is intended to cooperate with the third teeth 21b and fourth teeth 21c of the second gear 21 of the second display mobile unit 20. These two arms or levers 81, 82, in particular their beaks, interact with the teeth of the gears to enable angular indexing of the two display mobile units 10 and 20, as shown in Figure 2.

[0119] More specifically, the indexing of the first display mobile unit 10 is handled by a beak or head 81a, which is part of the arm 81. The head 81a has two sides 81b and 81c. The arrangement of these two sides, which cooperate by contact with the sides of the consecutive teeth of the first and second tooth rows 11b and 11c, enables the angular indexing of the first display mobile unit 10, as shown in Figure 10.

[0120] In a similar embodiment, the indexing of the second display mobile unit 20 is handled by a beak or head 82a which is part of the arm 82. The head 82a has two sides 82b and 82c. The arrangement of these two sides, which cooperate by contact with the sides of the consecutive teeth of the third and fourth tooth rows 21b and 21c, enables the angular indexing of the second display mobile unit 20, as shown in Figure 10.

[0121] The elastic return element 84 enables the elastic return of the arms or levers 81 and 82 using an interacting means 83, such as a lever, which allows for the transmission and distribution of force of the elastic return element 84 between the two arms or levers 81 and 82. Therefore, the interacting means interacts with or is positioned between the arms or levers 81 and 82 and the elastic return element 84. The elastic return element 84 is mechanically connected to the frame 99. For example, one end of the elastic return element 84 is mechanically fixed to the frame 99. The return element advantageously takes the shape of a leaf spring.

[0122] The interacting means 83 preferably includes a pin 86 guided within a groove 85 formed on the frame. The groove 85 associated with the pin 86 allows the interacting means 83 to provide a first degree of freedom of rotation, particularly around an axis parallel or substantially parallel to axis A5, and a second degree of freedom of translation, perpendicular to or substantially perpendicular to the centerline defined by axes A1 and A2 with respect to the frame.

[0123] In modified versions not shown, the pins may be formed in or fixed to the frame, and the grooves may be formed in the interaction means. In other words, in modified versions, the configuration may be reversed.

[0124] The interacting means 83 may include, in particular, an elastic return element 84 and a first contact area 83a or 83a' which cooperates with the second end of the leaf spring 84, a second contact area 83b or 83b' which cooperates with the first arm or lever 81, and a third contact area 83c or 83c' which cooperates with the second arm or lever 82, as shown in Figure 10.

[0125] The spring 84 transmits its return force to the interacting means 83 via the first contact area 83a or 83a'. The return force is then transmitted and distributed between the first and second arms 81 and 82 using the second and third contact areas 83b or 83b' and 83c or 83c', respectively.

[0126] A second embodiment of the jumper or indexing device 80 will be described below with reference to Figures 14 to 16.

[0127] The second embodiment of the jumper or indexing device 80 differs from the first embodiment of the jumper or indexing device 80 primarily or solely in the shape of the interacting means 83'.

[0128] In a second embodiment of the jumper or indexing device 80, the interacting means 83' advantageously has a globally square or trapezoidal cross-section in the plane of Figures 14 to 16 perpendicular to axes A1, A2, and A5.

[0129] The interacting means 83' includes, in particular, an elastic return element 84, and in particular a second end of a leaf spring 84, a first contact area 83a' that cooperates with the first arm or lever 81, and a third contact area 83c' that cooperates with the second arm or lever 82, as shown in Figures 14 to 16.

[0130] The first contact area 83a' may extend along the smaller base of the trapezoidal cross-section. This contact area advantageously constitutes a cam surface 89 adapted to equip the elastic return element 84 when the interacting means pivots around an axis perpendicular to the plane of Figures 14 to 16, particularly around the axis of the pin 86. In fact, in the positions shown in Figures 14 to 16, with respect to a stationary or neutral position as shown in Figure 10, where the surface 89 is substantially parallel to the end of the leaf spring 84, the interacting means 83' moves downward in translation, perpendicular to axis A5, in the direction of the leaf spring 84, and pivots around the axis of the pin 86. These motions cause a first motion or equip of the elastic return element 84 due to the translational motion of the interacting means 83', and a second motion or equip of the elastic return element 84 due to the rotation of the interacting means 83' via the cam surface 89. The cam surface 89 is arranged or adapted in the configurations of Figures 14 to 16 such that the installation of the elastic return element 84 is identical or substantially identical to that of the configuration in Figure 15, in which the interacting means moves downward in translation perpendicular to axis A5 and in the direction of the leaf spring 84, without or substantially without the interactioning means pivoting around the axis of the pin 86.

[0131] The distribution of force generated by the elastic return element 84 between the two arms 81 and 82 depends on the relative positions of the three contact areas 83a, 83b, and 83c or 83a', 83b', and 83c', the shape adopted by the arms 81 and 82 and the elastic return element 84 cooperating with the three contact areas 83a, 83b, and 83c or 83a', 83b', and 83c', the shape and guiding position of the means 83 or 83', and the relative positions between the arms 81 and 82.

[0132] In one modification, the first and second arms may consist of the same integrally cast or integrally constructed assembly. In this type of modification, the integrally cast or integrally constructed assembly may be adapted to allow degrees of freedom of rotation of the first and second arms about an axis parallel to, substantially parallel to, or coincident with, axis A5, for example, using a control rod cluster-type elastic pivot. The interacting means 83 or 83' may also be part of the integrally cast or integrally constructed assembly and, via elastic connections formed for this purpose, provide degrees of freedom of rotation of the first and second arms about an axis parallel to the axis of rotation, and a second degree of freedom of translation relative to the frame perpendicular to, or substantially perpendicular to, the centerlines defined by axes A1 and A2. The integrally cast or integrally constructed assembly may include a subframe fixed to the frame and adapted to be positioned so that the interacting means can contact the ends of a spring. For this reason, the proposed mobile unit indexing device may consist of multiple parts and / or one or more flexible guide parts that enable the combination of the functions described herein.

[0133] Regardless of the modification, the maximum dimension of the interacting means 83 or 83' is preferably at least twice or at least three times smaller than the maximum dimension of the first arm and / or the maximum dimension of the second arm.

[0134] In one modification, the shape of the elastic return element 84, the interacting means 83 or 83', the arms 81, 82, and the resulting contact areas 83a, 83b, and 83c or 83a', 83b', and 83c' may be modified to alter the distribution of force transmitted by the elastic return element 84 to the two arms or levers 81, 82 via the interacting means 83 or 83'. By similar reasoning, such shape modifications allow for alteration of the force generated by the elastic return element 84 and / or the variation in force, depending on the number of arms or levers acted upon. This makes it possible to adjust the return force at lever heights according to design requirements.

[0135] In one modification, the various degrees of freedom granted to the interacting means may be obtained without pins or grooves. For this purpose, the interacting means 83 or 83' must be directly guided, for example, by arms or levers 81, 82 and / or elastic return elements 84, and the shapes of these parts must be adapted for this purpose. In this type of design, it is also possible to provide auxiliary degrees of freedom, for example, a second degree of freedom of translation in a plane perpendicular to axis A5.

[0136] In the modified example, the rotation of the arms or levers 81 and 82 may not be coaxial.

[0137] In the modified configuration shown in Figure 10, the two arms or levers 81 and 82 act in opposite directions to each other with respect to axis A5. However, in alternative configurations, these two arms or levers 81 and 82 may be superimposed, particularly when the two display mobile units are superimposed or coaxial. In this case, the interacting means 83 or 83' may be advantageously mounted in a pivot connection around an axis parallel to the plane of Figures 11 to 13.

[0138] In one modified example, the mobile unit indexing device may similarly be implemented by translationally functioning arms or levers 81 and 82. In this case, the interacting means 83 or 83' is advantageously positioned to abut against each end of the translationally functioning arms or levers 81 and 82.

[0139] In different modifications, the elastic return element 84 may include, in particular, one or more blades, or a coil spring, a flexible guide, or other device to which a return torque or force can be applied. The elastic return element may include, in particular, two leaf springs separated at a portion that forms a cam adapted to cooperate with the interacting means.

[0140] In one modified example, an intermediate part may be added between the interacting means 83 or 83' and the elastic return element 84.

[0141] Extending this line of reasoning, the indexing device 80 can function similarly with two or more arms or levers.

[0142] The following describes the different operating conditions of the arms or levers 81 and 82, depending on the various possible sequences during the date jump.

[0143] Thanks to the arrangement and configuration of the interacting means 83 or 83', the deformation of the elastic return element 84 when both arms or levers 81, 82 are actuated is advantageously equivalent to or substantially equivalent to the deformation of the elastic return element 84 when only one of the two arms or levers 81, 82 is actuated. This results in equivalent or substantially equivalent energy consumption regardless of the number of arms or levers actuated.

[0144] An embodiment of the first operating method for the above-described device 100, the above-described clock movement 110, or the above-described clock 120 will be described below with reference to Figures 7 and 8.

[0145] The method is, - The first command mobile unit 30 drives the first display mobile unit 10, and / or - Simultaneously, the first command mobile unit 30 drives the first display mobile unit 10, and the first display mobile unit 10 drives the second display mobile unit 20 via the second command mobile unit 40, and / or - The first command mobile unit 30 drives the second display mobile unit 20, and / or - Simultaneously, the first command mobile unit 30 drives the second display mobile unit 20, and the second display mobile unit 20 drives the first display mobile unit 10 via the second command mobile unit 40. Includes.

[0146] An embodiment of the second operating method for the above-described device 80, or the above-described device 100, or the above-described clock movement 110, or the above-described clock 120 will be described below with reference to Figures 11 to 16.

[0147] The method is, - Steps of movement of the first arm and / or second arm due to the effect of movement of the first mobile unit 10 and / or second mobile unit 20, and steps of mounting the elastic return element 84 due to the effect of movement of levers 83, 83', - A step of returning the elastic return element 84 (i.e., a step of returning elastic potential energy) that causes rotational drive of the first mobile unit 10 and / or the second mobile unit 20 via levers 83, 83' and the first and / or second arms, particularly until the first and / or second mobile unit reaches the next resting or indexing position. Includes.

[0148] In the embodiments described with reference to Figures 14 to 16, the installation step preferably has the same intensity in at least two of the following situations: - The equipment is provided by the movement of the first mobile unit. - The equipment is provided by the movement of the second mobile unit. - The equipment is provided by the movement of the first and second mobile units.

[0149] The kinematic chains driving the display mobile units 10 and 20 by the command mobile units 30 and 40 differ depending on the jump date. Various possible scenarios are described below, with particular reference to the first modification of the first embodiment. A schematic diagram of Figure 7 illustrates these various scenarios.

[0150] The transition from "29" to "30". The display unit shows "29". The teeth 50a of the intermediate mobile unit 50 complete one step in the counterclockwise direction, driving the fifth teeth 30a of the first command mobile unit 30 in the clockwise direction. As a result, the fifth teeth 30a drives the first teeth 11b of the first display mobile unit 10 in the counterclockwise direction. The units digit display on the first display disk 12 changes from "9" to "0". The fifth teeth 30a does not drive the third teeth 21b of the second display mobile unit 20. However, as it rotates, the teeth 11c of the first display mobile unit 10 drives the sixth teeth 40a of the second command mobile unit 40, and then the sixth teeth 40a drives the teeth 21c of the second display mobile unit 20. The tens digit display on the second display disk 22 then changes from "2" to "3".

[0151] This driving principle remains the same for the transition from "09" to "10" and from "19" to "20".

[0152] The transition from "30" to "31". The display unit shows "30". The teeth 50a of the intermediate mobile unit 50 complete one step in the counterclockwise direction, driving the fifth teeth 30a of the first command mobile unit 30 in the clockwise direction. As a result, the fifth teeth 30a drives the first teeth 11b of the first display mobile unit 10 in the counterclockwise direction. The units digit display on the first display disk 12 changes from "0" to "1". The fifth teeth 30a does not drive the third teeth 21b of the second display mobile unit 20. However, as it rotates, the teeth 11c of the first display mobile unit 10 drives the sixth teeth 40a of the second command mobile unit 40, and then the sixth teeth 40a drives the teeth 21c of the second display mobile unit 20. The tens digit display on the second display disk 22 changes from "3" to "3" because the display of "3" is duplicated on disk 22.

[0153] This driving principle is the same for transitions from "10" to "11" and from "20" to "21," as the "1" and "2" displays also overlap.

[0154] The transition from "31" to "01". The display unit shows "31". The fifth tooth row 50a of the intermediate mobile unit 50 achieves one step in the counterclockwise direction, driving the fifth tooth row 30a of the first command mobile unit 30 in the clockwise direction. The fifth tooth row 30a is no longer able to drive the tooth row 11b of the first display mobile unit 10 because it is opposed to a tooth that is missing, removed, or not formed. The fifth tooth row 30a drives the tooth row 21b of the second display mobile unit 20 in the counterclockwise direction. The tens digit display on the second display disk 22 moves to the next tens digit, from "3" to "0". As it rotates, the tooth row 21c of the second display mobile unit 20 is no longer able to drive the second command mobile unit 40 via the sixth tooth row 40a because the tooth row 21c is missing, removed, or not formed. The first ones digit display disk 12 of the first display mobile unit 10 remains in place.

[0155] In the transition from the date "31" to "01" as shown in Figures 11 and 14, only the second display mobile unit 20 is driven.

[0156] In the first stage of the operation of the second arm 82, due to the influence of the rotation of the second display mobile unit 20, the second arm 82 is actuated in a first rotational direction, ascending the teeth of the tooth row 21b or 21c. As it rotates, the second arm 82 engages the elastic return element 84 via the interacting means 83 or 83'. More specifically, the second contact area 83b or 83b' abuts against the first arm 81, which is fixed in place, and the location where the second arm 82 abuts against the third contact area 83c or 83c' is movable, so the interacting means 83 or 83' rotates and translates in a first direction of motion within the groove 85.

[0157] In the second stage of the second arm 82's operation, following the passage over the apex of the teeth of tooth arch 21b or 21c, the second arm 82 is actuated in a second rotational direction by the effect of re-equipping the elastic return element 84 via the interacting means 83 or 83', descending the teeth of tooth arch 21b or 21c. The interacting means 83 or 83' rotates and here translates in a second direction of motion opposite to the first direction of motion.

[0158] Transition from "01" to "02". The display device shows "01". The fifth tooth row 50a of the intermediate mobile unit 50 achieves one step in the counterclockwise direction, driving the fifth tooth row 30a of the first command mobile unit 30 in the clockwise direction. The fifth tooth row 30a is no longer able to drive the tooth row 11b of the first display mobile unit 10 because it is facing a tooth that is missing, removed, or not formed. On the other hand, this fifth tooth row 30a drives the tooth row 21b of the second display mobile unit 20 in the counterclockwise direction. The tens digit display on the second display disk 22 moves to the next tens digit, "0", because the display of the tens digit "0" is duplicated on the disk 22. As it rotates, the tooth row 21c of the second display mobile unit 20 drives the sixth tooth row 40a of the second command mobile unit 40, and then the sixth tooth row 40a drives the tooth row 11c of the first display mobile unit 10. The units digit of the first display disk 12 changes from the units digit "1" to the units digit "2".

[0159] Here, as shown in Figures 12 to 15, the two display mobile units 10 and 20 are driven simultaneously.

[0160] In the first stage of the operation of the two arms, due to the rotation of the first and second display mobile units 10 and 20, the first and second arms 81 and 82 are actuated in a first rotational direction, ascending the teeth of the tooth rows 11b or 11c and 21b or 21c, respectively. As they rotate, the first and second arms 81 and 82 engage the elastic return element 84 via the interacting means 83 or 83'. More specifically, the interacting means 83 or 83' translates within the groove 85 in a first direction of motion, such that the combined effect of the first arm 81 abutting the second contact area 83b or 83b' and the second arm 82 abutting the third contact area 83c or 83c' engages the elastic return element 84 via the first contact area 83a or 83a'. Here, the motion of the interacting means 83 or 83' is translational or substantially translational motion. It is also possible to make the interacting means 83 or 83' pivotable. Nevertheless, this latent rotational motion has a small or very small amplitude compared to the translational motion.

[0161] In the second stage of the two arms' operation, following the passage of the apex of the teeth of tooth row 11b or 11c or 21b or 21c, the first and second arms 81 and 82 are actuated in a second rotational direction and descend the teeth by the effect of re-equipping the elastic return element 84 via the interacting means 83 or 83'. Here, the interacting means 83 or 83' translates in the second direction of motion, opposite to the first direction of motion.

[0162] This driving principle is the same for transitions from "11" to "12" and from "21" to "22," as the "1" and "2" displays also overlap.

[0163] Passing from "02" to "03". The display device shows "02". The fifth tooth row 50a of the intermediate mobile unit achieves one step in the counterclockwise direction, driving the fifth tooth row 30a of the first command mobile unit 30 in the clockwise direction. The fifth tooth row 30a drives the tooth row 11b of the first display mobile unit 10 in the counterclockwise direction. The units digit display on the first display disk 12 changes to the next units digit. On the other hand, the tens digit is not driven. In fact, the fifth tooth row 30a is no longer able to drive the tooth row 21b of the second display mobile unit 20 because it faces a tooth that is missing, removed, or not formed. Similarly, the tooth row 11c of the first display mobile unit 10 is also unable to drive the sixth tooth row 40a of the second command mobile unit 40 because the teeth of tooth row 11c are missing, removed, or not formed. For this reason, the second command mobile unit 40 and the second display mobile unit 20, more specifically the second display disk 22, remain in place.

[0164] In this case, as shown in Figures 13 and 16, only the first display mobile unit 10 is driven.

[0165] In the first stage of the operation of the first arm 81, due to the influence of the rotation of the first display mobile unit 10, the first arm 81 is actuated in a first rotational direction, ascending the teeth of the tooth row 11b or 11c. As it rotates, the first arm 81 engages with the elastic return element 84 via the interacting means 83 or 83'. More specifically, the third contact area 83c or 83c' abuts against the second arm 82, which is fixed in place, and the location where the first arm 81 abuts against the second contact area 83b or 83b' is movable, so the interacting means 83 rotates and translates in a first direction of motion within the groove 85.

[0166] In the second stage of the first arm 81's movement, following the passage over the apex of the teeth of tooth arch 11b or 11c, the first arm 81 is actuated in a second rotational direction by the effect of re-equipping the elastic return element 84 via the interacting means 83 or 83', descending the teeth of tooth arch 11b or 11c. Here, the interacting means 83 or 83' rotates and translates in a second direction of motion, opposite to the first direction of motion.

[0167] This driving principle also applies to other jumps from "03" to "09," as well as jumps from "12" to "13" and beyond to "19," and jumps from "22" to "23" and beyond to "29."

[0168] As can be seen from Figures 5 and 6, and as described above with reference to Figure 8, the teeth of the fifth dentition are preferably trimmed. In fact, trimming the ends of dentition 30a is particularly necessary to ensure that dentition 30a can cooperate with dentitions 11b and 21b only on the centerline passing through axes A1 and A2, so as not to risk dentition 30a moving away from the centerline and interfering with dentitions 11b and 21b.

[0169] Thanks to the solution described above, the drive is achieved by two separate command mobile units having substantially the same dimensions as the two gears 11 and 21 of the two display mobile units. Thus, the overall dimensions in plane are advantageously reduced while providing some flexibility in the arrangement and display order of the display mobile units.

[0170] These solutions also provide greater flexibility not only in the placement of the date display on the dial, but also in the dimensions of the display disc and the quality of the date display.

[0171] These solutions involve two separate command mobile units, each taking the form of a small gear, equivalent to or substantially equivalent to a gear fixedly attached to the tens digit disk and / or a gear fixedly attached to the units digit disk, rather than one large command mobile unit.

[0172] The proposed indexing device can, advantageously, employ a single return element adapted to return two arms or levers that can function independently or simultaneously. Therefore, this type of device can effectively solve the problem of fluctuations in the movement's energy consumption, which is linked to the simultaneous or non-simultaneous driving of two "Grande Date" display mobile units.

[0173] Thanks to the solution according to the present invention, the energy consumption of the movement when driving the "Grande Date" is the same or substantially the same whether there is one display mobile unit to be driven or two. To achieve this, the interaction means arranged between the elastic return element and the two arms that index the two display mobile units may be adapted to transmit substantially the same motion to the ends of the elastic return means in both cases, in a direction perpendicular or substantially perpendicular to the centerline passing through axes A1 and A2. Figures 11 and 13 illustrate means that move by a first amount in a direction perpendicular or substantially perpendicular to the centerline passing through axes A1 and A2 due to the effect of the motion of the first or second arm. Figure 12 illustrates means that move by a second amount in a direction perpendicular or substantially perpendicular to the centerline passing through axes A1 and A2 due to the effect of the simultaneous motion of the first or second arm. In the indexing devices shown in Figures 11, 12, and 13, the first and second amplitudes are particularly small so that the difference between these two amplitudes does not have any significant effect on the energy consumption of the movement. Therefore, the energy consumption required to drive the "Grande Date" mechanism is kept the same or substantially the same whether there is one or two display mobile units to be driven, and is preferably negligible compared to the energy consumed by the watch over a 24-hour period.

[0174] Of course, it is also entirely possible to adapt the first and / or second arms and / or interacting means such that the second amplitude of the motion of the means in a direction perpendicular or substantially perpendicular to the centerline passing through axes A1 and A2 is equal to the first amplitude of the motion of the interacting means in a direction perpendicular or substantially perpendicular to the centerline passing through axes A1 and A2. This type of adaptation is particularly preferred when the stiffness and / or pre-equipment of the springs is increased, especially for the purpose of ensuring the function of the indexing device. In this case, the energy required to drive the "Grande Date" mechanism remains the same or substantially the same whether there is one or two indicator mobile units to be driven.

[0175] Of course, it is also entirely possible to adapt the first and / or second arms and / or interacting means such that the amplitude of the motion of the interacting means in a direction perpendicular or substantially perpendicular to the centerline passing through axes A1 and A2 varies depending on the arm or multiple arms being actuated, and in particular depending on the number of arms being actuated. For this reason, the force transmitted to the arms may vary, in particular, according to the number of arms actuated or which arms are actuated.

[0176] The watch mobile indexing device solution may be used in other devices employing multiple indexing arms, such as day-date calendars, annual, semi-permanent, or permanent date calendars, or chronograph counting chains.

[0177] The clock mobile indexing device solution may also be used in a device in which, for example, an arm acts as a mobile unit brake, clutch clamp, or play compensation clamp. These devices can also be equivalent to an indexing system.

[0178] None of the identified prior art discloses an indexing device employing two levers or lever beaks, which are substantially identical in height, which can operate independently of each other or simultaneously in cooperation with a single return element, regardless of the number of beaks that are actuated. More specifically, none of the identified prior art discloses an indexing device of this type for a "grande-date" mechanism.

[0179] In this specification, “jumper” preferably means an indexing device comprising a beak that cooperates with a dental arch and, in particular, a cavity between two consecutive teeth of the dental arch, and is biased into the cavity by an elastic element, in order to define at least one indexing position of a mobile unit.

[0180] In this specification, “dentition” preferably means a set of one or more teeth.

[0181] In this specification, “mobile unit” preferably means an element that is rotatable about an axis and enables at least one complete rotation about the axis. The element may include a plurality of parts fixedly attached to each other in rotation about the axis. The mobile unit advantageously includes at least one set of teeth adapted to enable rotational drive of the mobile unit about the axis, particularly in meshing with other sets of teeth outside the mobile unit.
