    Technical field of the invention
    The present invention relates to a device for displaying a succession of periodic events which form an annual cycle. The present invention relates in particular to a device for displaying the sequence of periods of the zodiac. The present invention also relates to a timepiece comprising such a display device.
    Technological background of the invention
    An annual cycle can be divided into a number of periods which each include the same number of days or numbers of different days.
    For example, an annual cycle of twelve months can be divided into twelve periods, each corresponding to one of the twelve signs of the zodiac. The peculiarity of these zodiac periods is that their durations are not identical: these durations are indeed between 29 and 32 days. Furthermore, the transition from a zodiac period to the next zodiac period takes place between the 20th and the 23rd of the month concerned depending on the duration of the zodiac sign in question. For example, the zodiac period which corresponds to the sign of the sagittarius extends over 29 days from November 23 to December 21, while the zodiac period which corresponds to the sign of cancer lasts 31 days from June 22 to July 22 .
    An annual cycle can also be divided into twelve periods corresponding to the twelve months of the year. These months are of unequal duration, between 28 and 31 days.
    Display devices for these periods are already known. The most rudimentary forms of execution include a disc on which the different periods of an annual cycle are represented by angular sectors whose angle varies according to the number of days of the period considered. A first embodiment consists in rotating the disc under a dial in which is provided a window through which the current period is visible. Another form of execution consists in turning the disc opposite an index which points to the current period. Yet another embodiment is to rotate a needle above the disc, the needle pointing to the current period.
    The drive mechanisms of the disc on which are reported the different periods of an annual cycle or of the needle which moves over such a disc are of the jumping or dragging type and their advance is regular , so that the display of the current period lacks precision, especially when transitioning from one period to the next. Furthermore, displaying on a component of a timepiece time indications of different ranges while time itself is flowing at an equal rate, gives a rather poor perception of the timepieces concerned.
    A display device for periods forming an annual cycle is known from document EP 3 029 531 A1 in the name of Blancpain. The heart of this display device is constituted by a differential mechanism with two inputs and one output. A first input is constituted by a reference drive wheel arranged to perform a revolution according to a reference period. A second entry is constituted by an activation member arranged to cooperate with a cam which has a profile arranged in such a way that the cooperation between the activation member and the differential has the effect of advancing or retreating a member indicating the periods. depending on the difference between the displayed period and the reference period. Finally, the output is constituted by a drive member of the indicator member.
    Thanks to these characteristics, the Blancpain display device makes it possible to regularly represent periods which are not necessarily all equal to each other. Furthermore, the choice of a differential mechanism for animating the display device makes it possible to position the period indicator member at any location on the perimeter of the dial of the timepiece which is equipped with this display device. By cons, as is well known, a differential mechanism requires a large number of parts and is difficult to develop. Consequently, such a display device is rather reserved for high-end parts whose cost price is high.
    Summary of the invention
    The present invention aims to remedy the problems mentioned above as well as others by providing in particular a device making it possible to display equally a succession of periodic events of unequal durations which form a cycle annual.

    Detailed description of an embodiment of the invention
    The present invention proceeds from the general inventive idea which consists in providing a device making it possible to display in an equal and continuous manner periodic events which form an annual cycle and whose durations are not equal. To this end, the present invention provides a display device comprising a cam driven by a date and month indicator device and which, at the end of each month when necessary, pre-positions a rocker so that, when the day of the passage from a periodic event to the immediately following periodic event, a display unit displays the relevant periodic event. Thanks to these characteristics, the present invention thus provides a device for displaying periodic events forming an annual cycle which is continuously repositioned as a function of the day of the month when the periodic event to be considered begins. It is thus possible to display periodic events which do not necessarily follow one another regularly over time without this being perceptible by the owner of the timepiece.
    Care will be taken to note that, in the figures appended to this patent application, the directions of rotation of the various mobiles are indicated by arrows.
    Designated as a whole by the general reference numeral 1, the display device for a succession of periodic events which form an annual cycle according to the invention comprises a date indicator mechanism 3 which, in the form of preferred but not exclusive execution, is provided with a date driving wheel 2 which is driven by a clockwork movement (not shown) at the rate of one revolution per day. In turn, this date driving wheel 2 drives a date indicating wheel 4 at the rate of one step per day, this date indicating wheel 4 making a complete revolution in thirty-one days.
    A month finger 6 is pivotally mounted on the date indicator wheel 4 around a first pivot axis 8 carried eccentrically by said date indicator wheel 4. This month finger 6 also includes a first spout 10 a first tip 12 of which describes a first trajectory 14 of substantially conchoidal shape which is determined by an appropriate choice of the position of the pivot axis 8 on the date indicator wheel 4 and the length of this month finger 6. For that the tip 12 of the spout 10 can describe a conchoidal trajectory 14, the month finger 6 is also provided with a first oblong hole 16 in which is engaged a first pin 18 fixedly mounted in a plate of the clockwork movement and which ensures the pivoting and translational guidance of the month finger 6.
    The display device 1 according to the invention also comprises a wheel indicating the months 20 which advances one step per month and which makes one complete revolution per year. To this end, the month finger 6 is arranged so that, at each passage from the date "31" to the date "1" of the following month, the tip 12 of the spout 10 penetrates into a first toothing 22 of this wheel indicating the 20 months and takes the latter one step forward. After having driven the month indicator wheel 20, the tip 12 of the beak 10 of the month finger 6 emerges from the toothing 22 of the month indicator wheel 20 and will not engage with this toothing 22 until the passage of the calendar „ 31 “on the next“ 1 ”calendar In the meantime, the position of the month indicator wheel 20 is indexed by a first jumper spring 24.
    When the month indicator wheel 20 advances by one step, it drives with it a management cam 26 for the duration of display of the periodic events which is fixedly mounted on this indicator wheel for the months 20.
    The display device 1 described here is arranged to display the succession of the 12 signs of the zodiac. It will nevertheless be understood that this example is given for purely illustrative purposes and that, with an adaptation of the management cam 26, it is quite possible to display another succession of periodic events having the particularity of forming an annual cycle . We are thinking in particular of the display of the Chinese horoscope.
    In the so-called tropical zodiac system which is of interest here, the 12 periods of the zodiac begin, as the case may be, on 20, 21, 22 or 23 of the month concerned. Furthermore, when two successive zodiac periods do not start on the same day of the month, there is never more than one day of difference between the start of the first zodiac period considered and the start of the zodiac period immediately. next. More precisely, from March to May, the periods of the zodiac concerned, namely Aries, Taurus and Gemini, all start on the 21st of the month. The next zodiac period, that of cancer, begins on June 22. From July to November, the corresponding zodiac periods, namely Leo, Virgo, Libra, Scorpio and Sagittarius, all start on the 23rd of the month. In December, the Capricorn period begins on the 22nd, in January, the Aquarius period begins on the 21st, and in February, the Fish period begins on the 20th.
    As will be better understood later, the management cam 26 is arranged so that the display device 1 changes zodiac period on the first day of the zodiac period considered. Thus, a profile 28 of the management cam 26 has a first radius R1 which will allow the display device 1 to change the zodiac period on the night of 22 to 23 of the months of July, August, September, October and November. Similarly, the profile 28 of the management cam 26 has a second radius R2 different from the first radius R1 which will allow the display device 1 to change the zodiac period on the night of 21 to 22 June and December. Similarly, the profile 28 of the management cam 26 has a third radius R3, different from the first and second rays R1 and R2, which will allow the display device 1 to change the zodiac period during the night of 20 to 21 January, March, April and May. Finally, the profile 28 of the management cam 26 has a fourth radius R4, different from the first, second and third rays R1, R2 and R3, which will allow the display device 1 according to the invention to change the zodiac period in the night of February 19 to 20.
    Thus, the profile 28 of the management cam 26 has a first portion of radius R1 constant for the months of July, August, September, October and November, then a second portion of radius R2 for the month of December, then a third portion of radius R3 for the month of January, then a fourth portion of radius R4 for the month of February, then a fifth portion of radius R3 constant for the months of March, April and May, and finally a sixth and final portion with radius R2 corresponding to the month of June.
    According to the invention, the display device 1 also comprises a lever 30 pivotally mounted about a second pivot axis 32 fixedly mounted in the plate of the clockwork movement. This lever 30 has a feeler finger 34 by which it is applied against the profile 28 of the management cam 26. This lever 30 also carries a second pin 36 which projects into a second oblong hole 38 formed in a finger of the periodic events 39 for which it provides both pivoting and translational guidance. This finger for periodic events 39 which, in the example relating to the display of the zodiac system described here, is in the form of a zodiac finger 40, is pivotally mounted on the date indicator wheel 4 around a third pivot axis 42 carried eccentrically by said date indicator wheel 4. This zodiac finger 40 also includes a second spout 44, a second tip 46 of which describes a second trajectory 48 of substantially conchoidal shape which is determined by the positioning of the third pivot axis 42 on the date indicator wheel 4 and by the length of this finger of the zodiacs 40.
    The display device 1 according to the invention also comprises a zodiac indicator body 49. In the example shown in the drawing for illustration only, this member is a zodiac indicator wheel 50 which advances one step during of each change of zodiac period and which makes a complete revolution per year. To this end, the finger of the zodiacs 40 is arranged so that, at each change of zodiacal period, the tip 46 of its beak 44 penetrates into a toothing 52 of the indicator wheel of the zodiacs 50 and advances the latter by one step. . After having driven the indicator wheel of the zodiacs 50 by one step, the tip 46 of the beak 44 of the finger of the zodiacs 40 emerges from the toothing 52 of the indicator wheel of the zodiacs 50 and will not engage with this toothing 52 until the next change of zodiac period. In the meantime, the position of the indicator wheel for the zodiacs 50 is indexed by a second jumper spring 54. The mounting is completed, for example, by an indicator disc for the zodiacs 56 on which are indicated the zodiac indications, these zodiac indications being for example visible through a window provided in a dial of the timepiece and whose position is indicated by a double arrow on the drawing.
    It goes without saying that the present invention is not limited to the embodiment which has just been described and that various modifications and simple variants can be envisaged by those skilled in the art without departing from the scope of the invention as defined by the appended claims. In particular, it will be understood that, although the present invention has been described in connection with the display of the twelve periods of the zodiac, this invention is not limited to such an embodiment and can be applied to the display of other periodic events forming an annual cycle. We are thinking in particular of the display of the Chinese horoscope. It will also be understood that although, in the present description, only the case has been considered in which the month finger 6 and the finger of the zodiacs 40 are pivotally mounted on the date indicator wheel 4 around two pivot axes 8, 42 combined carried by said date indicator wheel 4, a simplified embodiment in which the month finger 6 and the finger of the zodiacs 40 are pivotally mounted around two distinct pivot axes carried by the date indicator wheel 4 is also conceivable. It will also be understood that, as illustrated in FIG. 6, the first tip 12 of the first beak 10 of the month 6 finger describes a trajectory of substantially conchoidal shape. By "circle conchoid" is meant a two-dimensional curve which represents the trajectory of a point Pl of a connecting rod, namely the 6-month finger, constrained to slide by a fixed pole F, namely the first pin 18 fixedly mounted in the plate of the watch movement, and of which a point C of this connecting rod describes a circle. By considering the point PE of the connecting rod located, starting from the circle described by point C, after the fixed pole F, we obtain the trajectory illustrated schematically in FIG. 1A that the tip 12 of the beak 10 of the finger of the months makes 6. The tip 46 of the beak 44 of the finger of the zodiacs 40 also describes a conchoid trajectory of a circle.
