Definitions

  • the present invention relates to the field of watchmaking, and more particularly to display devices of the phases of the moon.
  • Timepieces allowing such a display generally include a disc performing a turn in 59 days (or two lunar months of 29 days and a half, as is generally admitted), at the rate of one jump per day. This disc bears the design of two moons. It is arranged behind the dial and appears, partly masked, in a window. Such a display is approximate, and the available surface is relatively small
  • the document CH 598 638 proposes to equip the movement with a disc bearing figures representing the moon in its different neighborhoods.
  • the disc is equipped with fifteen figures and a wheel of fifteen teeth, driven every two days, so that it performs a turn in 30 days, which is far from the duration of the lunar month which is 29 days , 12 hours and 44 minutes.
  • the shape of the moon can be better respected, but the error is important. It corresponds to almost 7 days a year, the equivalent of a neighborhood.
  • An object of the present invention is to allow the realization of a display device of the moon phases by means of realistic images and large dimensions, appearing statically.
  • This device is characterized in that the mechanism is arranged so as to scroll successively and periodically the n images of the display means in one and a single lunar month.
  • the mechanism is arranged so as to scroll successively and periodically the n images of the display means in one and a single lunar month.
  • the display means are formed of a disk or a ring, advantageously disposed at the periphery of the movement.
  • Another object of the invention is to allow a more realistic display.
  • the disk is transparent and carries shades, while an image of the moon is fixed on a frame, covered by the disk.
  • the display means are formed of two disks, at least locally superposed.
  • the upper disk is provided with an open or transparent area through which the lower disk can be visible at least locally and periodically.
  • the number n of not qu'êtnt the display means is advantageously between 14 and 25.
  • n 16/59
  • the mechanism blows up the display means every 44 hours and 15 minutes, implying a ratio of gears equal to 16/59 between the hour wheel and the wheel control of the drive mechanism.
  • the watch shown in FIG. 1 comprises a box 10 provided with an ice through which a dial 12 and hands of hours 14 and minutes 16 appear. It furthermore comprises a display of the phases of the moon 18, appearing in FIG. a window 20 of the dial 12.
  • the device for displaying the phases of the moon is illustrated schematically in Figures 2 and 3 respectively in plan and in section, the line AA of Figure 2 showing the section plane.
  • This device is disposed on a frame 22 and comprises, carried by this frame, a transparent disk 24, for example sapphire, bearing sixteen silhouettes of the moon evenly distributed around its periphery.
  • This disc 24 is provided with sixteen teeth 24a for driving it in rotation.
  • the silhouette of the moon at noon is completely shaded, which corresponds to the new moon, while the one at six o'clock is completely transparent, corresponding to the full moon.
  • the disk 24 is driven by a mechanism 26 comprising, on the one hand, a wheel of the hours 28 performing two revolutions per day, provided with a pinion 28a and carrying, on a barrel, the hour hand 14, and other share a moon wheel 30, provided with a drive finger 30a.
  • the ratio of gears between these two wheels 28 and 30 is equal to 16/59, so that the jump of the disc 24 is made every 44 hours and 15 minutes.
  • This mechanism can be of any type usually used for the training of date discs, jumps however not being as frequent in the case of the device according to the invention.
  • a jumper 32 positions the disc 24 cooperating with the teeth 24a.
  • An image 34 of the moon is disposed on the frame 22, visible in transparency through the disc 24. It can be made for example by means of a precious metal pellet such as platinum or rhodium, and engraved to represent the craters. This image is more or less hidden by one or other of the silhouettes on the disc 24, which pass one after the other, with a frequency of 44 hours and 15 minutes, as explained above.
  • the disc 24 makes it possible to hide the moon in sixteen different configurations. It is obvious that this number may be higher or on the contrary lower, without departing from the scope of the invention. Below fourteen, however, the information begins to lack precision, whereas if that number exceeds twenty-five, the apparent image is significantly smaller. It will be noted however that by having a number of silhouettes multiple of four, it is possible to clearly display the new moon, the full moon and each of the neighborhoods.
  • the display means are formed of two superimposed disks 36 and 38.
  • the upper disk 36 is carried by a wheel 40, provided with a barrel 40a and pivotally mounted on a pin 42 integral with the frame 22, while the disc 38 is carried by a wheel 44, also provided with a barrel 44a and mounted on the barrel 40a of the wheel 40.
  • the discs 36 and 38 are fixed by driving on the free ends of the barrels 40a and 44a. They are not visible in FIG. 5 and will be described in more detail with reference to FIG.
  • the boards of the wheels 40 and 44 are provided with nine teeth at their periphery. Jumpers 46 and 48 respectively cooperate with the wheels 40 and 44 to position them. These boards furthermore each comprise eight pins 40b and 44b planted perpendicularly to their flat surfaces and arranged facing each other, with a pitch of 40 °, so that there is a space corresponding to two steps between two pins.
  • the boards also comprise fingers 40c and 44c which extend over circles of the same radius and each occupy an angle of 40 °, and arranged so as to cooperate with each other during the rotation of the wheels 40 and 44.
  • the wheels 40 and 44 are driven by a jumper 50, which is controlled by a cam 52 spiral.
  • the cam 52 is carried by a wheel 54 in engagement with the pinion 28a of the spur wheel 28, in a gears ratio of 16 to 59, so that the wheel 54 performs a revolution in 44 hours and 15 minutes, in one sixteenth of a lunar month.
  • the jumper 50 cooperates with a spring 56 which maintains it bears against the cam 52. It carries an arm 50a whose end is provided with a finger 50b located in the space occupied by the pins 40b and 44b. At each turn of the wheel 54, the jumper 50 arrives at the top of the cam 52 and drops sharply, the finger 50b driving one of the pins 40b and / or 44b.
  • Disks 36 and 38 shown in Figure 6, each have eight figures of the moon.
  • the disc 36 is provided with a cutout forming a window 36a through which it is possible to see the disk 38, while the disk 38 has a sector 38a without figure.
  • jumper 50 jumps every 44 hours and 15 minutes.
  • the finger 50b drives a pin of one of the wheels 40 or 44.
  • the other wheel remains fixed because it is positioned so that the finger 50b moves in the free space, c ie with pin.
  • it is admitted that, at first, it is the wheel 40 which is driven.
  • a new jump jumper 50 causes the drive of the two wheels 40 and 44, the wheel 44 being pushed by the action of the finger 40c on the finger 44c.
  • the wheel 40 is then in a position such that the finger 50b moves between two pins 40b, while the wheel 44 is rotated at each jump of the jumper 50, until the finger 44c comes push the finger 40c and thus engage the wheel 40, while the wheel 44 is disengaged.
  • the disks perform a complete cycle in sixteen jumps, each having a period of 44 hours and 15 minutes, so that a complete revolution is performed substantially in a lunar month.
  • the two disks can be centered on the needles 14 and 16, which makes it possible to display a moon of very large size.
  • the post 42 is replaced by the shafts of the mobile carrying the needles.
  • disks whose diameter is slightly less than the radius of movement, so that the device can be arranged between the center and the periphery. In this way, it occupies only a part of the neighboring surface of the display, thus making it possible to have other devices, displaying for example the day and the date, or ensuring a chronograph function.
  • the two disks are coaxial. It goes without saying that other variants are conceivable, for example by arranging the discs side by side. In this case also, the discs must be driven successively, with at least one simultaneous jump of the two discs to ensure the passage of the display from one to the other.
