Definitions

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.
An annual cycle can be divided into a number of periods which each include the same number of days or different numbers of days.
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.
the passage from a zodiac period to the following zodiac period takes place between the 20 and 23 of the month concerned depending on the duration of the zodiac sign in question.
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.
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 the different periods of an annual cycle are reported or of the needle which moves over such a disc are of the jumping or trailing type and their advance is regular, so that the display of the current period lacks precision, in particular 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 device for displaying periods forming an annual cycle is known from the 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 inlet is constituted by an activation member arranged to cooperate with a cam which has a profile arranged so that the cooperation between the activation member and the Differential has the effect of advancing or retreating a period indicator according to the difference between the displayed period and the reference period.
the output is constituted by a drive member of the indicator member.
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.
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.
the object of the present invention is to remedy the problems mentioned above as well as to others still further, in particular by providing a device making it possible to display equally a succession of periodic events of unequal duration which form an annual cycle.
the invention also relates to a timepiece comprising a device for displaying a succession of periodic events which form an annual cycle of the kind described above.
the present invention provides a mechanism for displaying periodic events forming an annual cycle whose construction is relatively simple and which is compact. Because of its relative simplicity of construction, the display mechanism according to the invention involves a smaller number of components, so that it is more economical to produce and that its operation is more reliable. On the other hand, since it is compact, the present display mechanism can be more easily accommodated in a larger number of calibers, without it being necessary to always have to touch up these calibers.
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.
the present invention provides a display device comprising a cam driven by a device indicating the date and month and which, at the end of each month where necessary, pre-positions a toggle so that, when the day of the transition from a periodic event to the immediately following periodic event occurs, 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.
the device for displaying a succession of periodic events which form an annual cycle comprises (see the figures 1 and 2 ) an indicator member 2 of the periodic events on which are reported the periodic events to be displayed.
the display device 1 also includes a management mechanism 4 for a duration of display of the periodic events.
This management mechanism 4 includes in particular a member 6 arranged to drive the indicator member 2 for periodic events during a change of event.
the management mechanism 4 also comprises a management cam 8 for the duration of display of the periodic events, and means 10 for driving the management cam 8.
the mechanism 4 for managing the duration of display of periodic events includes a date mechanism 12 driven by a clockwork movement (not shown).
This date mechanism 12 is provided with a date driving wheel 14 which rotates at the rate of one complete revolution per day and which includes a date driving finger 16.
the driving wheel calendar 14 advances by one step, via its calendar driving finger 16, a calendar indicator wheel 18 (see figure 3 ).
the date indicator wheel 18 is provided with a month driving finger 20 arranged on a circle concentric with the date indicator wheel 18 (see figure 4 ). On the 31st of each month, this month driving finger 20 advances by one step a month indicator wheel 22 on which is fixed the management cam 8 of the duration of display of the periodic events. It is understood that the month indicator wheel 22 and its associated management cam 8 make one complete revolution per year, advancing 30 ° at the end of the 31st of each month.
the information carried by the management cam 8 is communicated to a lever 24 mounted concentrically with the date indicator wheel 18 either directly or, as in the example shown in the drawing, via a hammer 26 provided with a feeler spout 28 which follows the profile of the management cam 8 and against which the lever 24 is held in elastic support by means of a return spring 30.
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 purely by way of illustration and that, with an adaptation of the profile of the management cam 8, it is entirely possible to display another succession of periodic events having the particularity of forming a annual cycle. We are thinking in particular of the display of the Chinese horoscope.
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, at namely ram, bull and gemini, all start on the 21st of the month. The next zodiac period, that of cancer, begins on June 22.
the corresponding zodiac periods namely Leo, Virgo, Libra, Scorpio and Sagittarius, all start on the 23rd of the month.
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.
the profile of the management cam 8 is arranged so that the indicator member 2 changes from zodiac period on the first day of the zodiac period considered.
the profile of the management cam 8 has a first radius R1 which will allow, via the hammer 26 and the rocker 24, the indicator member 2 to change the zodiac period during the night of July 22 to 23 , August, September, October and November.
the profile of the management cam 8 has a second radius R2 different from the first radius R1 which will allow the indicator member 2 to change the zodiac period during the night of 21 to 22 June and December.
the profile of the management cam 8 has a third radius R3, different from the first and second rays R1 and R2, which will allow the indicator member 2 to change the zodiac period during the night of 20 to 21 months January, March, April and May.
the profile of the management cam 8 has a fourth radius R4, different from the rays R1, R2 and R3, which will allow the indicator member 2 to change the zodiac period during the night of 19 to 20 February .
the profile of the management cam 8 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 last portion of radius R2 corresponding in the month of June.
the indicator organ 2 displays the zodiac period of Aquarius (see figures 5 and 6 ).
the flip-flop 24 is pre-positioned so as to allow the indicator member 2 to pass from the zodiac period of the aquarius to the zodiac period of the fish in the night of February 19-20.
the month driving finger 20 advances by one step the month indicator wheel 22 on which is fixed the management cam 8 of the duration of display of the periodic events.
the feeler beak 28 of the hammer 26 will pass from the fourth portion of radius R4 of the profile of the management cam 8 to the fifth portion of radius R3 of the profile of the cam management 8.
This change in the radius of curvature of the profile of the management cam 8 will be transmitted, via the feeler spout 28 of the hammer 26, to the rocker 24 which is held in elastic support against the hammer 26 by means of the return spring 30 .
the lever 24 adopts a new position which will then allow the indicating member 2 to pass from the indication of the zodiac period of the fish to the indication of the zodiac period of the ram shortly before midnight during the night of March 20 to 21. More specifically, during the period between the end of February and the following March 20, the date driving wheel 14 rotates at the rate of one revolution per day and advances the date indicator wheel 18 by one step. day. The 20 months advance canned coach finger with the calendar indicator wheel 18.
the position of the lever 24 is such that, during the passage of the 20 th to 21 th day of March, the month driving finger 20 rotates the satellite wheel 32 (see figure 8 ).
the lever 24 is held by its return spring 30 bearing against the hammer 26, it cannot pivot, so that the satellite wheel 32 drives the sun wheel 34 in rotation.
the solar wheel 34 advances by one step a zodiac indicator wheel 36 which carries the indications of the twelve signs of the zodiac and whose position is indexed by a jumper 38.
the indication of the zodiac passes from the fish to the ram.
the month driving finger drives the month indicator wheel and that, once a month, on the day of the change of zodiac period, the month driving finger drives the satellite wheel which it -even drives the zodiac indicator wheel via the sun wheel. It will also be understood that at the end of the months of less than 31 days, it is necessary to advance the date mechanism to the date "1" in order to guarantee that the display device according to the invention remains suitably indexed by schedule report.
