Definitions

  • the invention relates to an astronomical timepiece indicating the daily value of one or more astronomical quantities with an annual cycle, such as the time of sunrise / sunset, the declination of a celestial body or the like, through a window. made in the dial. These parts are mainly intended to be fitted in watches of the wristwatch type.
  • the invention also relates to a disc for displaying astronomical quantities.
  • Timepieces are already known, in particular astronomical watches which indicate the values of an astronomical magnitude varying daily. These values are indicated by means of needles, which move one step per day opposite a graduated scale representative of a determined quantity.
  • these are watches comprising movements of very great complexity, which in particular have planetary gear mechanisms with planet wheels with multiple mobiles. These mechanisms therefore have a high compactness and are consequently too expensive to be mass produced.
  • the surface available for display is relatively small, so that the reading of the astronomical values is not easy and therefore often imprecise.
  • the main object of the present invention therefore is to remedy the drawbacks of the prior art by providing a timepiece allowing the display of the daily value of an astronomical quantity with an annual cycle in a simple and precise manner and in addition for a small increase in the cost of the part.
  • the invention relates to an astronomical timepiece for the indication of at least one astronomical quantity with an annual cycle varying daily comprising a clockwork movement.
  • it comprises a first disc driven by said movement in monthly steps to effect a revolution in a year, and a dial provided with at least one window associated with each astronomical magnitude through which a part of said first disc is visible, said timepiece comprising for each aperture, a first graduation indicating the value of the date or a date value, a second graduation indicating the value of said astronomical magnitude and a set of segments of curves carried by said first disc, said segments cooperating with said graduations to indicate at least one daily value of said astronomical magnitude and being arranged so as to appear successively in said aperture during the rotation of the first disc.
  • the timepiece comprises a single window for each astronomical quantity, each curve segment associated with this window representing the successive daily values of said astronomical quantity for one month.
  • the graduations are carried by the dial and each arranged along consecutive edges of the window.
  • the present invention also relates to a disc for displaying an astronomical magnitude comprising a plurality of display surfaces on each of which a curve appears. representative of the daily variation of an astronomical value during a given period.
  • FIG. 1 there is a plan view of a wristwatch designated by the general reference 1.
  • This watch 1 of generally circular shape, conventionally comprises a case 2 having horns 3 for the fixing the bracelet (not shown). As it appears in FIG. 2, the watch also includes a clockwork movement 4 with a time-setting rod and carrying a dial 6 as well as unreferenced hands.
  • the housing 2 comprises a middle part 7 at the upper part of which is fixed a glass 8, and a bottom 9 at its lower part.
  • the dial 6 carries conventional time divisions 10 and is further crossed by three concentric axes carrying the hour, minute and second hands respectively.
  • the movement of the watch leads step by step to a date crown 11 at the rate of one step per 24 H.
  • This crown wears classic, on its face 12 directed towards the dial 6, the indication of the 31 calendar of the month.
  • the movement drives a 13 month disc step by step at the rate of one step per month, this disc performing a complete revolution in one year.
  • a device for driving the month disc can for example comprise a finger secured to the date crown driving once a month a return wheel which cooperates with the month disc, associated with a jumper ensuring its positioning.
  • the watch shown in FIG. 1 includes windows 14, 15, 16, 17, 18 through which a part of the month disc is visible.
  • Each of the counters is associated with an astronomical magnitude with an annual cycle varying daily.
  • the windows 14, 15 and 18 are associated respectively with the time of sunrise, the time of sunset and the solar declination. These windows are arranged in the form of sectors of concentric rings of different diameters. The information concerning the astronomical quantities carried by the disc of the months appears through the windows 14, 15 and 18 in the form of segments of curves.
  • each window 14, 15 is provided with a graduation and constitutes a first axis which can be considered as the abscissa axis.
  • the graduations written along this axis indicate values related to the astronomical magnitude displayed in the window, namely the time of sunrise and the time of sunset respectively.
  • each aperture 14, 15 is also provided with a graduation and thus constitutes a second axis which can be considered as an ordinate axis.
  • the graduations carried along this ordinate axis indicate, in the case shown, the date values.
  • the lower edge 21 or upper of the window 18 is provided with a graduation indicating the values of the dates and the lateral edge 24 is provided with a graduation indicating the values of an astronomical quantity, in this case an angular value of solar declination.
  • the windows 16 and 17 formed in the dial 6 in a ring of the same diameter are intended to reveal the indication of the current month and the calendar respectively.
  • the window 16 is made between 9 and 10 hours while the window 17 is made between 2 and 3 hours so that they are not aligned along the same diameter.
  • FIG. 3 there is a plan view of a 13 month disc according to the invention.
  • This 13-month disc includes on its face opposite the dial a plurality of graphics. These graphics are arranged on four concentric rings 28, 29, 30, 31 of different diameters in correspondence with the diameters of the rings in which the windows 14, 15, 16, 17, 18 are provided. Starting from the larger diameter ring, the first 28, the third 30 and the fourth 31 are each associated with an astronomical quantity while the second 29 conventionally indicates a numbering of the months, represented here in Roman numerals.
  • Each ring 28, 30, 31 associated with an astronomical magnitude is divided into twelve sectors 28a, 30a, 31a, and on each of them there is a segment of curve 25, 26, 27 corresponding to the evolution daily during a month of the year of the associated astronomical magnitude.
  • the first ring 28 comprises twelve sectors 28a, each comprising a segment of curve 25, indicating the daily evolution of the time of sunrise during the twelve months of the year, this ring 28 cooperating with the window 14 located at twelve o'clock on the dial 6.
  • the second ring 29 presents the indication of the months, the sign of the current month being visible through the window 16 formed in the dial. Furthermore, this second ring 29 includes twelve apertures 32 formed between each sign of the month. These apertures 32 cooperate on the one hand with the date crown 11 so that the latter is permanently visible through one of the apertures 32, on the other hand with the aperture 17 provided in the dial 6.
  • the third ring 30 presents information substantially identical to that of the first ring 28, namely the daily evolution of the sunset time in the form of segments of curves 26. This third ring 30 is visible through a window 15 provided also at twelve o'clock along a diameter smaller than the previous two.
  • the fourth ring 31 also divided into twelve sectors 31a indicates in the form of a curve 27 the daily angular values of the solar declination, this curve 27 being visible through a window 18 formed at six o'clock.
  • these rings can be divided into more or less sectors.
  • the pitch of the disc and the size of the windows, the indications and the associated graduations will be adapted.
  • the lower edge 19 of the windows 14 can indicate the value of the astronomical magnitude while the date can be indicated along each segment 25 of the curve by means of indexes I, the latter being produced in an example of graphic represented in figure 4 by the ends of the rays of the sun.
  • the segments of curves associated with an astronomical magnitude appearing in a window 33a can be placed end to end and forming a continuous curve 33b extending along a ring, this being particularly interesting for the indication of the curve representative of the equation of time.
  • FIG. 7 an alternative embodiment of a timepiece according to the invention is seen, comprising for each astronomical magnitude three apertures 37, 38, 39.
  • Each aperture is associated with a determined date.
  • the first window 37 is associated with the first day of the month
  • the second window 38 is associated with the 15th day of the month
  • the third window 39 is associated with the 30th day of the month.
  • the astronomical magnitudes being the time of sunrise / sunset
  • the first windows 37 are located respectively at 10 am and 4 hours
  • the third 39 windows at 8 hours and 2 hours.
  • These windows 37, 38, 39 have an oblong configuration and extend in a radial direction in the middle part of the dial 6.
  • Each window 37, 38, 39 is provided on one of its longitudinal edges 37a, 38a, 39a with a graduated scale making it possible to indicate the value of the astronomical magnitude for the date associated with the window.
  • This value is determined by an index 37b, 38b, 39b visible through windows, this index being carried by the month disc.
  • This index 37b, 38b, 39b is in fact a segment of curve appearing through a window so that one can easily interpolate the value of the astronomical magnitude for a date between the 1st and the 15th and the 15th and the 31st of the month.
  • the dial 6 also includes a window 17 (located at 3 o'clock) showing an indication concerning the month, the astronomical information indicated by the index being directly linked to it.
  • a particularly pleasant aesthetic effect can be obtained by choosing to wear on this telescope the equation of time represented by a continuous curve 41.
