Definitions

  • the present invention relates to date mechanisms. It relates more particularly to a mechanism of the large window type, thanks to which the reading of the date is facilitated.
  • Such a mechanism is described in the document WO 98/50829 . It comprises an annular control wheel performing a turn per month and provided with first and second teeth, which drive two display mobiles respectively bearing the numbers of the units and tens.
  • the control wheel is concentrically arranged with the needles.
  • the display mobiles are arranged side by side, inside the ring formed by the control wheel, and off-center with respect to the latter.
  • the control mobile can be achieved by modifying a conventional date disc. It is thus possible to provide an existing template with a large window display, with a minimum of modifications.
  • Such a solution implies a date at noon or at 6 o'clock, in the middle part of the dial, with relatively modest dimensions of the wicket.
  • the document WO 99/13383 relates to a mechanism also comprising a control mobile performing one turn per month.
  • This mobile ensures, furthermore, the display units. It drives a mobile tens display superimposed on the disk units and provided with cutouts through which appear the numbers of units.
  • the tens control and display mobiles are off-center with respect to each other. This solution is even simpler than the previous one.
  • the display should be at 6 o'clock or noon, and the maximum dimension of the displayed figures remains modest.
  • the document CH 688 671 refers to a date mechanism Comprising display mobiles tens and units that are concentric with each other, but offset with respect to movement. Display mobiles are both driven by a gear train.
  • first and second gear trains respectively engaged with the first and second) teeth and with the wheels of the first and second display mobiles, the first gear set being disposed at a first and second gear first level, higher, and the second gear train at a second, lower level, and in that said disks are superimposed.
  • This mechanism is advantageously intended to equip a timepiece provided with a pivoting needle display in the center of the movement, the wheels of the display mobiles being disposed at the center of the movement.
  • the second gear set is arranged so that the second display mobile, displaying the tens, performs four steps per revolution.
  • This mobile display is provided with a disc bearing the indications "0" or "nothing", "1", "2" and "3".
  • the second gear set is arranged so that the second display mobile, displaying the tens, performs five steps per revolution.
  • This display mobile is provided with a disc bearing the indications "0" or "nothing", "1", “2", “3” and "31".
  • the teeth of the drive wheel are advantageously formed of pins.
  • the watch shown in FIG. 1 comprises, in a conventional manner, a box 10, a dial 12 provided with a window 14, a date display 16 and hour hands 18, minutes 20 and seconds 22.
  • the date display 16 and the hands 18, 20 and 22 are moved by a movement mounted in the housing that forms the box 10 and which will be partially described with reference Figures 2 and 3.
  • a crown setting time 24 corrects the information displayed.
  • the movement shown in plan in Figures 2a and 2b, is shown in section along the lines AA and BB respectively in Figures 3a and 3b.
  • It comprises a basic structure 26, schematically illustrated and formed of a frame carrying a power source, a time base, a gear wheel rotating in synchronism with the time base, and mechanisms, time setting controlled by the crown 24, and date causing the display 16.
  • the wheel comprises movers arranged in the center of the movement and provided with shafts 28, 30 and 32 for carrying respectively the needles18, 20 and 22.
  • the basic structure 26 carries a date module 34 which will be described in more detail below.
  • the date mechanism of the basic structure causes, in known manner, a disk in place of a control wheel 36 and making a turn in one month. It is provided with two teeth 36a and 36b formed of pins arranged perpendicularly to the plane of the disc.
  • the module 34 comprises a plate 38 mounted on the frame of the base structure 26 by means of screws not shown and extending over most of its surface.
  • the plate 38 carries two gear trains 40 (Figure 3b) and 42 ( Figure 3a), respectively engaged with the teeth 36a and 36b.
  • the plate 38 is provided, in its central part, with a barrel 38a concentric with the trees 28, 30 and 32 and surrounding them.
  • Two display mobiles 44 and 46 are pivotally mounted on the barrel 38a.
  • the mobile 44 comprises a disk 44a, which carries the numbers of the date units, and a pinion 44b engaged with the gear train 40 and on which the disk 44a is fixed.
  • the mobile 46 is pivotally mounted on the mobile 44.
  • It comprises a disk 46a, bearing the digits of the tens, and a pinion 46b meshing with the gear train 42, and on which the disk 46a is fixed.
  • the numbers of teeth of the pinions 44b and 40c are chosen so that, for a quarter turn of the pinion 40c, the pinion 44b is one tenth of a turn. In this way, at each step of the control wheel 36, and to the extent that the toothing 36a has a pin, the wheel 40a is a quarter turn and the pinion 44b a tenth of a turn, which corresponds to the passage of a number of units to the next.
  • the numbers of teeth of the pinions 46b and 42c are chosen so that, for a third turn of the pinion 42c, the pinion 44b makes a quarter turn.
  • the wheel 42a is a third of a turn and the pinion 46b a quarter turn, which corresponds to the passage of a numbers from tens to the next.
  • the wheels 40a and 42a and 40d and 42d are respectively pivotally mounted on the plate 38 by means of pins 48, 50, 52 and 54.
  • the pins of the toothing 36a are arranged in a circle on the annular disk that forms the mobile 36. They are longer than the pins of the teeth 36b, also arranged in a circle on the mobile 36, the diameter of this second circle being smaller than that of the first.
  • the wheel 40a is at a first level, upper, chosen so that its board 40b is engaged with the toothing 36a, but does not come into contact with the toothing 36b.
  • the wheel 42a is at a second, lower level, the cutouts in its board 42b being engaged with the toothing 36b.
  • control wheel 36 drives the disks 44a and 46b through the gear trains 40 and 42. It is understood that the disks must be driven in a sequence such that the tens change at each pass from 9 to 0 units and the display goes from 31 to 1 at the end of each month.
  • Figure 4 shows more precisely how this sequence is defined.
  • the disk of the tens 46a and 4b the disk of the units 44a.
  • Part 4c has a table shape with, in the first line, the date displayed with which is associated a position of the control wheel 36, in the second line the displayed tens, in the third line the structure of the teeth 36b, in fourth line the units displayed and in the fifth line the structure of the toothing 36a.
  • the tens disk 46a as shown in 4a, has a central portion and four arms, each of them bearing a number, namely the sequence 0, 1, 2 and 3.
  • the disc 46a must jump during the passage from 9 to 10, 19 to 20, 29 to 30 and 31 to 1, under the action of the teeth of the toothing 36b shown in the third row of Table 4c.
  • the toothing 36b comprises four pins arranged so as to drive the disk 46a at each change of ten.
  • the disk units 44a shown in 4b must jump every day except when going from 31 to 1. This is why, as can be seen in the fifth line of Table 4c, the toothing has thirty pins and a space between the pins respectively ensuring the passage of 30 to 31 and 1 to 2.
  • FIG. 5 represents, according to the same structure as that of FIG. 4, a display variant in which the disk of the tens 46a comprises five indications, namely 0, 1, 2, 3 and 31.
  • the toothing 36b comprises five pins respectively providing the jump of the disc 46a during the passage from 9 to 10, from 19 to 20, from 29 to 30, from 30 to 31 and from 31 to 1.
  • the disk units 44a it can be driven during the passage from 30 to 31. It can also be driven during the passage from 31 to the first, as shown in this figure.
  • pinions 44b and 46b are advantageously positioned by means of jumpers cooperating with their toothing. These are not shown, however, to avoid overloading the drawing.
  • control wheel 36 and the display mobiles 40 and 42 are concentric with each other and with the shafts carrying the hour, minute and second hands. It is also possible to realize a mechanism in which the control wheel is off-center with respect to the movement.
  • the display mobiles are, here too, arranged concentrically to the control mobile. In this case, the display is smaller, but still interesting. These mobiles can be concentric to a shaft carrying a complementary display needle, indicating, for example, the second.
  • control mobile and display mobiles are concentric, it is possible to achieve a large date display, by simple means.
