Definitions
- the present invention relates to a perpetual calendar display system with secular correction and in particular such a system mounted in a timepiece.
- the object of the invention is to propose a perpetual calendar display system providing the secular corrections provided for by the Gregorian calendar, or even millennia not provided for by the Gregorian calendar, in a simple manner (little increase in parts and adaptation possible current mechanism) and compact (little increase in thickness compared to current mechanisms and integration into the parts of current mechanisms).
- the invention relates to a system for displaying the perpetual calendar of a Gregorian calendar
- a system for displaying the perpetual calendar of a Gregorian calendar comprising at least one date display coupled to a device for driving the date display intended to increment d a date display unit every twenty-four hours, and a counting device intended to control the drive device in order to selectively increment the date display according to a predetermined number of additional units, at the end of the month , depending on the number of days of the month, characterized in that the display system comprises a 12 or 48 month cam mechanism and in that the counting device is arranged to form a stop used for counting leap years whose distance relative to an axis of rotation of the 12 or 48 month cam is selectively adjustable in the thickness of the 12 or 48 month cam in order to bring the secular corrections of the Gregorian calendar [ 0007]
- the distance of the stop is selectively adjusted with respect to the axis of rotation, typically respectively in 12 or 48 steps distributed over three hundred and sixty degrees, depending on the leap years by integrating it
- the display system takes into account the fact that secular years divisible by hundred (for example one thousand nine hundred, two thousand hundred, etc.) are not leap years, unless they are divisible by four hundred (for example two one thousand, two thousand four hundred, etc.) where they remain a leap year.
- the adaptation of the 12 or 48 month cam mechanism generates a small increase in parts and therefore makes it possible to use a mechanism whose operation is already made reliable. It is also immediate that the adaptation is advantageously integrated into the thickness of the 12 or 48 month cam mechanism which allows a thickness which is not increased in the case of secular corrections.
- the invention may also comprise one or more of the following optional characteristics, taken alone or in combination.
- the 12 or 48 month cam mechanism may comprise a large rocker intended to come into contact with the stop of the counting device in order to determine whether the date display should selectively display the twenty-ninth day of the month of February of the year. It is understood that the large rocker of the 12 or 48 month cam mechanism does not have to be particularly adapted for the display system according to the invention to operate.
- the counting device may comprise a finger-Maltese cross set provided in the thickness of the 12- or 48-month cam in order to form a gear train with respect to the 12-month cam. or 48 months.
- the reduction is adapted so that the Maltese cross makes one revolution in preferably 20 years.
- the counting device preferably comprises a secular mobile, made in the thickness of a toothed wheel coaxially integral with the 12- or 48-month cam.
- a first part of the thickness may comprise a toothing intended to cooperate with a finger coaxially integral with the Maltese cross, and a second part of the thickness may comprise a cam track intended to cooperate with a follower of the cam track controlling moving the stop used for counting leap years.
- the complete gear train is adapted so that the secular mobile makes one revolution in preferably four hundred years.
- the stop used for counting leap years can therefore be formed by a pin moving relative to one of the February month reliefs of the 12- or 48-month cam in order to be able to selectively apply a month of February to twenty-eight or twenty-nine days.
- a rectilinear or curved displacement relative to the axis of rotation of the cam of 12 or 48 months can be envisaged without departing from the scope of the invention.
- a radial displacement of the stop that is to say oriented along a radius starting from the axis of rotation of the cam of 12 or 48 months, can be achieved.
- the counting device may comprise a finger-Maltese cross assembly, made in the thickness of a toothed wheel coaxially integral with the 12- or 48-month cam, in order to form a gear cog relative to the 12 or 48 month cam.
- the reduction is adapted so that the Maltese cross makes one revolution in preferably 20 years.
- the counting device preferably comprises a secular mobile, made in the thickness of the cam of 12 or 48 months.
- a first part of the thickness may comprise a toothing intended to cooperate with a finger coaxially integral with the Maltese cross, and a second part of the thickness may comprise a cam path intended to form the stop used for counting leap years.
- the complete gear train is adapted so that the secular mobile makes one revolution in preferably four hundred years.
- the stop used for counting leap years is preferably formed by the secular mobile itself.
- the second embodiment therefore comprises fewer parts than the first embodiment.
- a rotary displacement of the stopper that is to say around an axis offset from the axis of rotation of the cam by 12 or 48 months, can be achieved.
- the stop used for counting leap years can therefore be formed by the movable cam path forming part of one of the February month reliefs of the 12- or 48-month cam. in order to be able to selectively apply a month of February with twenty-eight or twenty-nine days. It can be considered a rectilinear or curved movement with respect to the axis of rotation of the cam of 12 or 48 months or even a rotation around an axis offset with respect to that of the cam of 12 or 48 months without depart from the scope of the invention.
- a rotary displacement of the cam track makes it possible to correct the relief (bump, flat or hollow) of the 12 or 48 month cam, that is to say according to its orientation with respect to the relief , it plugs, stops or hollows out the latter in order to selectively control the range of motion of the large seesaw.
- the counting device can, according to a particular variant, be further arranged to form a counter-stop which, mounted directly above the relief of the 12- or 48-month cam used for counting leap years, via an additional gear train, allows a leap year to be removed every four thousand years in relation to the Gregorian calendar.
- the display system therefore uses a 12 or 48 month cam mechanism adapted to correct the Gregorian calendar. More specifically, the display system in the millennial variant removes a leap year from years that are multiples of four thousand (e.g. four thousand, eight thousand, etc.) to provide a better approximation of the duration of a tropical year by imposing, using the counter-stop, for example to go from February twenty-eight four thousand directly to March first four thousand, whereas normally according to the Gregorian calendar, the year four thousand is a leap year.
- four thousand e.g. four thousand, eight thousand, etc.
- the adaptation of the cam mechanism of 12 or 48 months generates a small increase in parts and therefore makes it possible to use a mechanism whose operation is already made reliable. It is also immediate that the adaptation is advantageously integrated into the thickness of the cam mechanism of 12 or 48 months this which allows a slightly increased thickness compared to that with simple secular corrections.
- the invention relates to a timepiece comprising a watch movement, characterized in that it comprises the display system as presented above coupled to the watch movement.
- FIGS. 2 to 4 are partial views of a first variant of a first embodiment of a Gregorian calendar display system according to the invention
- FIGS. 5 and 6 are partial views of a second variant of the first embodiment of a Gregorian calendar display system according to the invention
- FIGS. 7 and 8 are partial views of a millennial variant of the first embodiment of a Gregorian calendar display system according to the invention
- - Figures 9 to 12 are partial views of a second embodiment of a Gregorian calendar display system according to the invention.
- orientations are the orientations of the figures.
- the terms “upper”, “lower”, “left”, “right”, “above”, “below”, “forward” and “backward” generally mean with respect to the direction of representation of the figures.
- timepiece 2 is meant all types of instruments for measuring or counting time such as clocks, small clocks, watches, etc.
- watchmaker's movement 3 we mean all types of mechanism capable of counting time, whether they are powered by mechanical energy (for example a barrel) or electricity (for example a battery).
- the invention relates to a timepiece 2 comprising a display system 1 coupled, for example by the hour wheel, to a watch movement 3 and intended to display at least a date display 4 of a Gregorian calendar.
- the display system 1 may comprise, in addition to the date display 4, a display 5 for the day of the week and a display 6 for the month of the year.
- the invention advantageously makes it possible to display a perpetual calendar providing at least the secular corrections provided for by the Gregorian calendar, in a simple and compact manner. More precisely, the display system 1 takes into account the fact that the secular years divisible by hundred (for example one thousand nine hundred, two thousand one hundred, etc.) are not leap years, except if they are divisible by four hundred (for example two thousand, two thousand four hundred, etc.) where they remain a leap year.
- the perpetual calendar display system 1 of a Gregorian calendar uses a modified 12 or 48 month cam mechanism and not such a mechanism to which a bulky external module has been added to provide the secular corrections. More specifically, it comprises the date display 4 moved by a drive device 7, itself selectively corrected by a counting device 9.
- the device 7 for driving the date display 4 is intended to increment the date display 4 by one unit every twenty-four hours.
- the drive device 7 comprises in particular a large rocker 11 provided with at least one lever 12. The drive device 7 not being modified with respect to a cam mechanism of 12 or 48 months, it will not be d advantage described below.
- Figures 2 to 12 show examples only with a 48-month cam mechanism.
- the invention can also be applied to a 12-month cam mechanism, that is to say forming a selectively movable abutment on the cam leap years in order to bring in an equivalent manner the secular corrections provided for by the Gregorian calendar, or even millennia not provided for by the Gregorian calendar.
- the counting device 9 is intended to control the drive device 7 in order to selectively increment the date display 4 according to a predetermined number of additional units, at the end of the month, according to the number of days of the month. of the Gregorian calendar.
- the counting device 9 comprises a beak 13 formed on the lever 12 and a counting mobile 15 making it possible to count the months in four-year cycles.
- the counting wheel set 15 comprises at least one toothed transmission wheel 16 coupled to the watch movement 3 and integral coaxially with a 48-month cam 17, that is to say that the toothed wheel 16 and the 48-month cam 17 are integral in rotation around the same axis A.
- the counting device 9 is arranged to form a stop 19, 39 used, by contact with the free end of the spout 13, to count the years leap year.
- the stop 19, 39 has a distance from the axis A of rotation of the cam of 48 months which is selectively adjustable in the thickness E of the cam 17 of 48 months in order to bring the secular corrections of the Gregorian calendar.
- the invention advantageously makes it possible to keep a similar operation of the cam mechanism 17 of 48 months (the large rocker 12 of the 48-month cam mechanism 17 does not, for example, have to be adapted for the display system 1 according to the invention to operate) while allowing the 48-month cam mechanism 17 to faithfully respect the Gregorian calendar.
- the display system 1 takes into account the fact that the secular years divisible by hundred (for example one thousand nine hundred, two thousand one hundred, etc.) are not leap years, except if they are divisible by four hundred (for example two thousand, two thousand four hundred, etc.) where they remain a leap year.
- the adaptation of the cam mechanism 17 of 48 months generates a small increase in parts and allows the use of a mechanism whose operation is already made reliable. It is also immediate that the adaptation is advantageously integrated into the thickness of the cam mechanism 17 of 48 months, which allows a thickness which is not increased in the case of secular corrections.
- a single stop 19 is preferably moved into one of the four recesses 21 of the month of February of the cam 17 of 48 months in order to be able to selectively apply a month of February to twenty-eight or twenty-nine days.
- the abutment 19 is formed by a movable cam track forming part of one of the four February month recesses 21 of the 48 month cam 17 in order to be able to selectively apply a month of February at twenty-eight or twenty-nine days.
- the counting device 9 comprises a cam 17 of 48 months making one turn in four years in the usual way.
- the cam 17 of 48 months receives in its thickness E a pin 20 forming the stop 19, a Maltese cross 23 and a finger 24.
- the pin 20 can slide in the recess 21 to change the depth of the recess 21.
- the Maltese cross 23 is pivotally mounted on the shaft B (attached to the plate of the wheel 16) and comprises five wings 22 intended to cooperate with the finger 24.
- the finger 24 is fixed, that is to say is mounted on a point of the watch movement 3, and it is the rotation of the mobile 15 around the axis A which will allow contact between the Maltese cross 23 and finger 24.
- the finger 24 - Maltese cross 23 assembly thus makes it possible to form a gear train fully integrated into the 48-month cam.
- the reduction is adapted so that the Maltese cross 23 makes one turn preferably in 20 years by passing one of the five wings 22 of the Maltese cross 23 through the finger 24 at each full cam 17 rotation of 48 months every four years.
- the counting device 9 further comprises a toothed wheel 16 coaxially fixed to the cam 17 of 48 months making one revolution in four years in the usual way.
- the wheel 16 receives in its thickness a secular mobile 25, a control follower 28 and a tenon 29 (hidden in FIG. 4 but comparable to that of FIG. 6).
- the secular mobile 25, pivotally mounted against the outer diameter of the circle 30 centered on the axis C, comprises, on a first lower part of its thickness, a toothing 26 intended to cooperate with the tenon 29 coaxially fixed to the cross of Malta 23, and, on a second upper part of its thickness, a cam track 27 intended to cooperate with the follower 28 of the cam track controlling the movement of the stop 19, the distance from the axis A of which is selectively adjustable.
- the cam track 27 has three notches 31 distributed successively every ninety degrees in order to take into account the secular years divisible by one hundred (for example one thousand nine hundred, two thousand one hundred, etc. ) that are not a leap year, unless they are divisible by four hundred (e.g.
- the notches 31 conversely allow the abutment 19 to be moved deeper into the recess 21 (equivalent to the fixed depths of the other recesses 21 of the month of February) so that the counting device 9 imposes, at most, a twenty-eighth day of February in years divisible by one hundred but not by four hundred, as, for example, in the year two thousand one hundred, two thousand two hundred and two thousand three hundred.
- the complete gear train is adapted so that the age-old wheel set 25 makes one turn, preferably in four hundred years, by the passage of one of the twenty teeth of the toothing 26 through the tenon 29 at each complete rotation. of the Maltese Cross 23 every twenty years.
- a second variant of the first embodiment is illustrated in the examples of Figures 5 and 6, the counting device 9 essentially differs from the first variant by the environment at the level of the pin 20 'causing a reversal of direction of the mobile 25' and tenon 29.
- the cam 17 of 48 months receives in its thickness E a pin 20' forming the stop 19, a Maltese cross 23 and a finger 24.
- the pin 20' is elastically mounted in cantilever of an elastic arm 32 and can move in a recess 21' widened in comparison with the first variant of the first embodiment.
- the Maltese cross 23 and the finger 24 are identical to the first variant.
- the secular mobile 25 ' pivotally mounted against the outer diameter of a circular part 30 'of the wheel 16, comprises, on a first upper part of its thickness, a toothing 26 intended to cooperate with the tenon 29 coaxially fixed to the Maltese cross 23, and, on a second lower part of its thickness, a cam track 27' intended to cooperate with the follower 28' of the cam track controlling the movement of the stop 19 whose distance from the A axis is selectively adjustable.
- a toothing 26 intended to cooperate with the tenon 29 coaxially fixed to the Maltese cross 23, and, on a second lower part of its thickness, a cam track 27' intended to cooperate with the follower 28' of the cam track controlling the movement of the stop 19 whose distance from the A axis is selectively adjustable.
- the cam path 27' comprises three notches 31' distributed successively every ninety degrees as in the first variant in order to take into account the secular years divisible by one hundred (for example one thousand nine hundred , two thousand one hundred, etc.) which are not a leap year, unless they are divisible by four hundred (two thousand, two thousand four hundred, etc.) where they remain a leap year. [0044] Consequently, similarly to the first variant, the cam track 27' allows the follower 28' - pin 20' assembly and therefore incidentally the stop 19 to be moved most of the time in the 'recess 21' so that the counting device 9 maintains a twenty-ninth day of February such as for example in the year two thousand or two thousand four hundred and all other years not divisible by one hundred.
- the notches 31 ' conversely allow the stop 19 to be moved deeper into the recess 21' (equivalent to the fixed depths of the other recesses 21 of the month of February) so that the counting device 9 imposes, at most , on a twenty-eighth day of February in years divisible by one hundred but not by four hundred as, for example, in the year two thousand one hundred, two thousand two hundred and two thousand three hundred.
- the complete gear train is adapted so that the age-old wheel set 25' makes one turn preferably in four hundred years by the passage of one of the twenty teeth of the toothing 26 by the tenon 29 at each rotation full of the Maltese Cross 23 every twenty years.
- the stop used for counting leap years is preferably formed by the secular mobile itself.
- the second embodiment therefore comprises fewer parts than the first embodiment.
- a rotary displacement of the stopper that is to say around an axis offset from the axis of rotation of the cam by 12 or 48 months, can be achieved.
- the counting device 9 comprises a cam 17 of 48 months making one revolution in four years in the usual way.
- the 48-month-old cam 17 receives, in its thickness E, the age-old wheel set 45 forming the stop 39 and a tenon 49.
- the age-old wheel set 45 pivotally mounted (along an axis offset from to that of the cam 17 of 48 months) against the internal diameter of a circular part of the cam 17 of 48 months, comprises, on a first upper part of its thickness, a toothing 46 intended to cooperate with the tenon 49 integral coaxially of a Maltese cross 43 (located in the thickness of the toothed wheel 16), and, on a second lower part of its thickness, a cam track 47 intended to cooperate with the beak 13 thus forming several stops 39 for change the depth of the recess 21” depending on the rotation of the mobile 45 secular. It will be understood that the recess 21” opens opposite the cam track 47.
- the cam track 47 has three notches 51 distributed successively every ninety degrees to take into account the secular years divisible by hundred (for example one thousand nine hundred, two thousand one hundred , etc.) that are not leap years, unless they are divisible by four hundred (two thousand, two one thousand four hundred, etc.) where they remain a leap year.
- the movable cam track 47 therefore complements the February month recess 21” of the 48 month cam 17 in order to be able to selectively apply a twenty-eight or twenty-nine day month of February.
- the displacement is rotary in order to close or extend the recess 21” of the cam 17 by 48 months allowing the amplitude of movement of the large rocker 11 to be selectively controlled.
- the counting device 9 further comprises a toothed wheel 16 coaxially integral with the cam 17 of 48 months making one revolution in four years in the usual way.
- the wheel 16 receives in its thickness a finger 44 and the Maltese cross 43.
- the Maltese cross 43 is pivotally mounted on the shaft B (attached to the plate of the cam 17 of 48 months) and has five wings 42 intended to cooperate with the finger 44.
- the finger 44 is fixed, that is to say is mounted on a point of the watch movement 3, and it is the rotation of the mobile 15 around the axis A which will allow contact between the Maltese cross 43 and the finger 44.
- the assembly thus makes it possible to form a gear train fully integrated into the toothed wheel 16.
- the reduction is adapted so that the Maltese cross 43 makes one turn preferably in 20 years by passing one of the five wings 42 of the Maltese cross 43 through the finger 44 at each full cam 17 rotation of 48 months every four years.
- the notches 51 conversely make it possible to lengthen or extend the recess 21” to place a stop 39 closer to the axis A (equivalent to the fixed depths of the other recesses 21 of the month of February) so that the device 9 of counting imposes, at most, a twenty-eighth day of February in years divisible by one hundred but not by four hundred, such as for example in the year two thousand one hundred, two thousand two hundred and two thousand three hundred.
- the complete gear train is adapted so that the age-old wheel set 45 makes one turn preferably in four hundred years by the passage of one of the twenty teeth of the toothing 46 by the tenon 49 at each complete rotation. of the Maltese cross 43 every twenty years.
- the counting device 9 can, according to a particular variant, called millennial, be further arranged to form a counter-stop 59 which, mounted plumb with the relief of the cam of 12 or 48 months used for the counting of leap years, via an additional gear train, makes it possible to remove a leap year every four thousand years in relation to the Gregorian calendar.
- the counting device 9 is adapted from the first variant of the first embodiment of Figures 2 to 4 to apply the millennial variant.
- the 48-month-old cam 17 is adapted by adding a notch 31 to the secular mobile 25 in order to distribute the notches 31 symmetrically, that is to say that they are distributed to equal consecutive angles with respect to the center C, along the cam track 27, here every ninety degrees of the circular cam track 27.
- the second adaptation concerns the follower 28 controlling the pin 20 which has an extra thickness compared to the first variant of the first embodiment in order to be able to continue to come into contact with the cam track 27 but also with a cam track 67 forming against the stop 59 in an upper plane.
- the counting device 9 in the millennial variant, comprises an additional gear train formed by a finger 64 - mobile 65 millennial assembly in order to use the complete rotation of the mobile 25 secular relative to the wheel 16 toothed so that the counting device 9 removes a twenty-ninth day of February every four thousand years.
- the finger 64 is fixed on the toothed wheel 16, that is to say is mounted integral or formed in a single piève with, and centered on the axis C of rotation of the mobile 45 secular. It is therefore the rotation of the mobile 65 millennium around the axis C which will allow contact between the toothing 66 of the mobile 65 millennium and the finger 64.
- the mobile 65 millennial pivotally mounted against the outer diameter of the shaft D (offset with respect to the axis C of rotation of the mobile 45 secular), comprises, on a first upper part of its thickness, a toothing 66 intended to cooperate with the finger 64 (located in the thickness of the toothed wheel 16), and, on a second lower part of its thickness, a cam track 67 intended to cooperate with the follower 28 thus forming several counter-stops 59 to change the depth of the recess 21 depending on the rotation of the mobile 45 secular and the mobile 65 millennial.
- the complete gear train is adapted so that the age-old wheel set 65 makes one revolution preferably in four thousand years by the passage of one of the ten teeth of the teeth 66 by the finger 64 at each complete rotation of the mobile 45 secular every four hundred years.
- the cam track 67 includes a notch 71 to take into account the millennial years divisible by four thousand (four thousand, eight thousand, etc.) which are not leap years.
- the movable cam track 67 therefore allows the pin 20 comprising the abutment 19 to sink further into the recess 21 of the cam 17 by 48 months every four thousand years in order to be able to selectively remove a month of February from twenty-nine days in relation to the Gregorian calendar, in favor of a 28-day month of February.
- the display system 1 therefore uses a 48-month cam mechanism adapted to correct the Gregorian calendar.
- the display system 1 in the millennial variant removes a leap year (four thousand, eight thousand, etc.) to provide a better approximation of the duration of a tropical year by imposing, using the counter - stop 59, for example to go from February twenty-eight four thousand directly to March first four thousand whereas normally according to the Gregorian calendar, the year four thousand is a leap year.
- the invention is not limited to the embodiments and variants presented and other embodiments and variants will appear clearly to those skilled in the art. Thus, the embodiments and variants can be combined with each other without departing from the scope of the invention. In addition, it may be envisaged to find technical equivalents of the elements presented above without departing from the scope of the invention. In no way limiting, other types of gear train than those presented above may in particular be provided.
