The support 3 comprises a crown 6, a toothed wheel 7 and two arms 9. Each arm 9 comprises an upper arm 91 and a lower arm 92. The toothed wheel is mounted on the crown. The toothed wheel has 62 teeth. For example, four holes are provided on the crown or on the toothed wheel and four internal threads 13 are provided on the toothed wheel or on the crown. Four screws 14 pass through the holes and are screwed into the threads. Alternatively, the toothed wheel can be mounted by other means on the crown, for example they can form a single piece. The crown comprises openings 15. The arms extend outside the periphery of the crown radially with respect to an axis A1 of symmetry of the crown. The arms have an overall T-shape. The upper arms are attached to the crown. The lower arms form an extension of the crown. The upper arms are fixed to the crown, for example, with two holes on each of the arms. The support for its part has four threads 17. Positioning spacers 18 arranged on the crown are provided at the level of the lower arms to keep the lower and upper arms at a distance from each other. Four screws 19 pass through the holes and are fixed in the threads. The two pairs of upper and lower arms are preferably identical. The two pairs of arms are advantageously positioned at 180 ° relative to one another relative to the axis A1. The function of the arms is to each guide an indicator 101, 102. The support 3 is mounted so as to be able to rotate in the watch movement about the axis A1. In particular, it is mounted mobile in rotation on a frame 20. A jumper 10 is fixed on the frame. The jumper cooperates with the teeth of the toothed wheel so as to index the support in position. The movement comprises a date finger 11 arranged so as to cooperate with the toothed wheel to cause it to advance by one step every 24 hours. Alternatively, the support may have only one arm and therefore guide a single indicator. Advantageously, in this case, the toothed wheel comprises only 31 teeth and / or the horological information indications are distributed over 360 °.

The first indicator 101 comprises a pallet 1, a shaft 8, a first cam 5 and a second cam 55. The first indicator is linked by a pivot link of axis A2 parallel to the axis A1 to the support 3. In in particular, the pivot connection is made between the lower 92 and upper 91 arms, on the one hand, and the first indicator 101, on the other hand. More precisely, the pivot connection is made at the end of the arms. The shaft has several bearing surfaces 81, 82 and 83. A first bearing surface 81 is intended to cooperate with a lower guide ring 811 so as to guide the first indicator in rotation along the axis A2. The lower guide ring is embedded in a bore of the lower arm 92. The first bearing surface is also able to support the first cam. The first cam is mounted in a sliding connection on the shaft 8, for example with two pins 551 planted in the first bearing. Once the first indicator is assembled, the first cam is fixed relative to the shaft. Alternatively, the first cam could be driven onto the shaft. The two pins are in particular arranged at 180 ° with respect to each other along the axis A2. The first cam is provided with a bore capable of cooperating with the first bearing surface of the shaft. The bore comprises two grooves 552 and 553 provided to cooperate with the pins 551. A second bearing surface 82 is intended to cooperate with an upper guide ring 821 so as to guide the first indicator in rotation along the axis A2. The upper ring is embedded in a bore of the upper arm 91. A third bearing surface 83 is intended to cooperate with the pallet. The pallet is linked by embedding on the shaft at the level of the third span. The pallet is for example driven out on the third staff. The pallet is crossed by the axis A2 at one end thereof. The pallet is substantially rectangular in shape. In the case of a rectangular pallet, the pallet is for example crossed by the axis A2 at the level of a small side thereof. The visible surface of the palette is red, more generally the visible surface of the palette is a bright color and / or a color contrasting with the color of the horological information indications. The pallet is arranged under a dial 115 bearing the indications of horological information. The pallet has dimensions allowing the reading of the indications. The length of the pallet is substantially equal to the length taken by the indications. The width of the pallet is substantially equal to the width taken by the indications. The first cam has an outer profile 554 adapted to cooperate with the spring system 4.

The spring system comprises a lever 41 (or hammer) and a spring 42. A face 43 of the lever 41 rests in contact against the outer profile 554 of the first cam 5. The profile 554 has a first zone Zm1 characterized by a minimum distance R1 from the axis A2 and a second zone Zm2 characterized by the minimum distance R1 from the axis A2. These two zones are preferably arranged at 180 ° to each other relative to the axis A2. The profile also has a third zone ZM1 characterized by a maximum distance R2 from the axis A2 and a fourth zone ZM2 characterized by the maximum distance R2 from the axis A2. These two zones are preferably arranged at 180 ° to each other relative to the axis A2.

The spring 42 is preferably a leaf spring. The shape of the spring system is substantially V. The base of the V is mounted on the lower arm 92. The base of the V is pivotally mounted about an axis A3, shown in Figures 5 and 8, parallel to the axes A1 and A2. A pin 400 whose axis coincides with the axis A3 is planted in the lower arm. The pin 400 cooperates with a bore 401 provided in the spring system to produce the pivot connection. The spring system is arranged between the lower arm 92 and the upper arm 91. The spring bears against a pin 44. The pin 44 is planted in the lower arm. One wing of the V is the lever and the other wing is the spring. The V is advantageously in one piece.

The second cam 55 and the shaft 8 are for example in one piece. The second cam 55 has a variable radius between a minimum and a maximum. The second cam comprises a large radius RC1 suitable for a portion of the profile of the second cam to interfere with obstacles 210 during rotation of the support. The second cam comprises a small radius RC2apte so that another portion of the profile of the second cam does not interfere with the obstacles 210 during a rotation of the support. These two rays are for example arranged at 180 ° to each other relative to the axis A2.

The first subset 320 of indications of horological information 2 comprises, in this embodiment, the indications of odd dates arranged in increasing order along a first path 220, in particular a curve. The first path, in particular a first circular arc 220, visible in FIG. 6, extends over an angle substantially equal to 180 °. The axis A1 is the axis of the arc of a circle 220. The first subset of horological information indications 2 is supported by the dial 115. The first trajectory is the trajectory that the indicator 101 would describe during the course. one month if it remained in its first stable position shown in Figure 6.

The second subset 321 of horological information 2 comprises, in this embodiment, the even date indications arranged in increasing order along a second path 221, in particular a curve. The second path, in particular a second circular arc 221, visible in FIG. 6, extends over an angle substantially equal to 180 °. The second circular arc has a radius smaller than the radius of the first circular arc. The second circular arc is centered on the A1 axis. The second subset of horological information 2 is supported by the dial 115. The second trajectory is the trajectory that the indicator 101 would describe over the course of a month if it remained in its second stable position shown in FIG. 7.

Even and odd dates are for example printed on the dial. In the embodiment shown, the dial is transparent or partially transparent and the indications are printed on the dial. Advantageously, the dial also comprises a translucent or opaque angular sector 106, ie a mask, intended to mask an indicator when the latter is not active, as will be described below.

An elementary interval specific to the horological information considered separates two successive horological information. This elementary interval is generally one unit. In particular, it can also be a day in the case of days of the week. Advantageously, the indication of the first of the two horological information forms part of the first subset of indications and the indication of the second of the two horological information items forms part of the second subset of horological information. Thus, the indications can be staggered and distributed between the two sub-assemblies.

The obstacles are mounted in complete connection on the frame or on the dial. The obstacles are for example arranged according to a third curve 230 and according to a fourth curve 231. The third curve and the fourth curve form in particular and respectively a third circular arc 230 and a fourth circular arc 231. The axis A1 is the axis of the third and fourth concentric arc of a circle. The third circular arc and the fourth circular arc extend through an angle of 180 ° or approximately 180 °. The radius of the third circular arc is greater than the radius of the fourth concentric circular arc.

In the embodiment shown, the watch indications 2 displayed are dates. However, the horological information may be days of the week, and / or months, and / or years, and / or the number of the week, and / or the hour, and / or the minute, and / or the second, and / or the moon phases.

In the embodiment described, the pointing or display of the indication of the watch information by the first indicator 101 is done by means of the palette, in particular a colored palette or contrasting with the color of the indications of 'watch information, arranged under watch information 2. The positioning of the pallet under an indication brings out this indication among all of all the indications.

[0033] According to another embodiment, the pointing or display of the horological information can be achieved by a transparent palette colored or contrasting with the color of the indications of horological information which is arranged above the indication. watchmaking information.

[0034] According to another embodiment, the pointing or display of the horological information can be carried out by a pallet provided with a window, the pallet being arranged above the indication of horological information.

[0035] According to another embodiment, the pointing or the display of the horological information can be carried out by a hand. Advantageously, according to this other embodiment, the hand can be placed below, above or at the same level as the indication of the horological information. The hand may carry a circle at its end, the circle being arranged below, above or at the same level as the indication of the horological information in order to point this indication. Any other indicating means can be used.

The operation of the embodiment mentioned above is described below: Consider a timepiece comprising the device 100 for displaying horological information, in particular the date of the current month. Without loss of generality, we consider that it is 11:59 p.m., the first date of a given month. In order to give this horological information, the indicator 101 indicates the date number 1 as represented in FIG. 6, the pallet being positioned under the indication “1”. In this position, the support 3 being in a stationary position and the first cam 5 is in one of its positions of stable equilibrium. When the 60th second of the previously considered minute has elapsed, the date finger 11 rotates the toothed wheel by one step by the cooperation between the date finger and a tooth of the toothed wheel 7. These elements are illustrated in FIG. 4 in order to have a view of the elements used in the drive of the support 3 to perform the date jump.

The support 3 comprising the toothed wheel 7 undergoes a movement around the axis A1. The support carries with it the spring system 4 and the first 101 and second 102 indicators. During movement of the support, as shown in FIGS. 9 to 11, the second cam 55 encounters on its path an obstacle 210 forming part of the plurality of obstacles which can be arranged at regular intervals. Some of the obstacles can be seen, for example, in FIGS. 8 to 14. As the race of the support continues, the second cam 55 abuts against the obstacle and consequently turns around the axis A2 of the shaft with which it is integral. . The first cam 5 and the pallet 1 also being integral with the shaft, they also rotate. The first cam 5 leaves a stable equilibrium position in which it was before the second cam 55 encounters an obstacle 210.

Indeed, from the stable position shown in Figure 8, when the support has performed a fraction of a step, the second cam 55 comes into contact against an obstacle 210 as shown in Figure 9. Thus, the first indicator rotates as shown in Figures 9, 10 and 11 under the effect of the action of the obstacle 210 on the second cam 55. The first cam 5 returns to a stable equilibrium position when the second cam 55 is no longer in contact with the obstacle 210 as illustrated in FIG. 7 where the support 3 is in a stationary position and the first cam 5 is in one of its positions of stable equilibrium.

Furthermore, the geometry of the profile 554 of the first cam 5 is such that by cooperation with the spring system 4, the first cam has two positions of rest or of stable equilibrium around the axis A2. The cooperation of the first cam and the spring system is achieved by pressing the face 43 of the lever 41 against the profile of the first cam as can be seen, for example, in FIGS. 8 to 14.

When the second cam 55 rotates around the axis A2 of the shaft 8, this rotation is transmitted to the first cam via the shaft A2. Thus, by the rotation of the first cam, the spring 42 will be armed by means of the lever 41. The spring thus sees its tension increase. Once a maximum tension has been reached, that is to say when the face 43 of the lever 41 is in contact with the zone ZM2 of the first cam, the first cam is in unstable equilibrium and the spring has in this position a potential energy maximum elasticity. By releasing its elastic energy, the spring 42 is able to return, then to maintain the first cam in a stable position opposite to the stable position occupied by the first cam 5 before the winding of the spring. The positions of the first cam 5 are stable when the spring has a minimum elastic energy, that is to say when the face 43 of the lever 41 is in contact with the zone Zm1 of the first cam 5. In FIG. 2, the kinematics of cooperation between the first cam 5 and the spring system 4, as well as the evolution of the mechanical stresses to which the spring is subjected, are shown.

As seen above, in Figure 8, the first indicator 101 is in a stable equilibrium position with respect to the support, the face 43 of the lever 41 bears against the zone Zm2 of the first cam and the spring has thus a minimum elastic energy. In FIG. 9, the support 3 has started to rotate around the axis A1. The second cam 55 comes into contact with an obstacle 210 thus forcing the second cam to rotate about the axis A2. By rotating around the axis A2, the second cam 55 also rotates the first cam 5 around this axis. The face of the lever remains in contact with the profile of the first cam by means of the spring 42. By rotating around the axis A2, the radius of the first cam in contact with the lever increases. Increasing the radius increases the spring tension. Figures 10 and 11 show the evolution of the rotation of the first indicator. The second cam is always in contact against the obstacle thus forcing the rotation of the first cam around the axis A2 as the support 3 rotates. In Figures 10 and 11, the tension in the spring increases as the radius of contact between the first cam 5 and the face 43 of the lever increases. FIG. 11 shows the face 43 of the lever 41 bearing against the zone ZM2 where the radius is maximum. At this moment, the spring is under maximum tension and the balance of the first cam is unstable. The spring then has maximum elastic energy. The second cam 55 and the obstacle 210 are still in contact at this moment. Figure 12 shows the positioning of the vane and cams an instant after passing from the unstable equilibrium position. In this configuration, the lever releases the energy of the spring by pressing against the profile 554 of the first cam 5 so as to bring the first indicator in position such that the face of the lever is in contact against the zone Zm1 opposite with respect to the position shown in FIG. 8. In this configuration, the second cam 55 is no longer in contact with the obstacle. In Figure 13, the first indicator 101 is again in a stable position. The movement of the support 3 then continues into the position illustrated in FIG. 14. FIGS. 8 and 14 show the first cam 5, and therefore the first indicator 101, in two opposite stable positions relative to the axis A2.

Thus, during the rotation of a pitch around the axis A1 of the support 3, the first indicator 101 performs two distinct movements: a rotation of an angular pitch around the axis A1 (1/62 of turn around axis A1) and simultaneously the first indicator undergoes a second movement which is a rotation of half a turn around axis A2. The first indicator 101 thus passes from a first position of stable equilibrium to a second position of stable equilibrium. These two movements make it possible to pass the first indicator 101 from a first position pointing the indication "n" in the second sub-assembly as shown in figure 8 to the second position pointing the indication "n + 1" in the first subset as shown in Figure 14, with n a natural number between 1 and 30.

In the embodiment described, the second cam 55 alternately meets, during rotation of the support, an obstacle arranged on the third obstacle curve, then an obstacle arranged on the fourth obstacle curve.

In the embodiment described above, when the current month has 31 days, for example the month of December, the passage from the last date of the month, that is to say from the date number 31, to the first date of the following month, that is to say the date number 1, is done in a different way. Indeed, the arrangement of the indications of horological information, in this case the date, extending only over approximately 180 °, two pallets are arranged in diametrically opposed position relative to the support 3 in order to be able to perform a display transition. . To understand this transition, you must first describe the kinematics of the first indicator located under date number 31 at 11:59 p.m. in December and secondly describe the kinematics of the second indicator located in the position preceding the display of the date. number 1 at midnight in January.

Regarding the first indicator located under date 31 at 11:59 p.m., when going to midnight, the kinematics remains the same as that described above when going from date number 1 to date number 2, that is to say say that the first indicator will once again undergo two movements, a rotation of an angular step around the axis A1 and a rotation of half a turn around the axis A2. Once these movements have been made, the first indicator is found advantageously hidden and invisible to the user. Preferably, over the following 180 ° of rotation of the support around axis A1, the first indicator no longer encounters any obstacle. Thus, the first indicator 101 no longer changes its stable position relative to the support but only performs angular increments around the axis A1. Advantageously, the first indicator remains hidden under the mask 106 provided for this purpose until the last day of the current month. The first indicator therefore remains inactive for a month, in our example until January 31, so on January 31 at 11:59 p.m. the first indicator is not visible. When going from January 31 to February 1 at midnight, the first indicator will undergo the same kinematics as described above (two rotational movements) and display date 1 or point to the indication "1". When the first indicator 101 disappears or leaves its position pointing to the indication of the last value of the horological information, the second indicator 102 appears or arrives in a position pointing to the indication of the first value of the horological information.

When the current month has a duration of less than 31 days, for example during a month of April, the change from date number 30 to date number 1 for the month of May, is done manually. To do this, the display device comprises a control member 415, in particular a control rocker 414 which, when it is tilted in one direction, makes it possible to advance the toothed wheel 7 by one step, and when it is tilted in a direction. another opposite direction makes it possible to move the toothed wheel 7 back by one step. The rotation of the toothed wheel by one step causes the displacement of the first and second indicators as described above. The latch 414 is returned to an intermediate position by a spring 413.

In the embodiment described, the toothed wheel is formed of 62 teeth, in order to perform 1/62 <th> of a turn at each increment at midnight and therefore to have an active indicator every other month, that is to say that each indicator displays or indicates horological information during a given time interval, in particular one month, then does not display or indicates no horological information during a following time interval, in particular the next month. The two time intervals are therefore without intersection. The first and second indicators are alternately active. Their activity states are preferably exclusive: when one is active, the other is inactive.

In the embodiment described, the date indications are arranged in concentric semicircles. However, the date indications could alternatively be arranged otherwise. For example, the date indications could be arranged in two concentric circles over 360 ° or could be arranged in two segments of parallel straight lines. In the latter case, the indicator could be on board a retrograde system.

In the embodiment described, the support is movable relative to the frame and the date indications and the obstacles are fixed relative to the frame. However, in another embodiment not shown, the support is fixed relative to the frame and the date indications and the obstacles are movable relative to the frame. For example, the date indications and the obstacles can be on board the same mobile system with respect to the frame. In this other embodiment, the support can be formed directly by the frame. Thus, the indicator or indicators can be movably mounted directly on the frame.
