Definitions

  • the present invention relates to date mechanisms. She more particularly a mechanism of the type with a large window, thanks to which the reading of the date is facilitated.
  • Such a mechanism is described in WO 98/50829. It has a mobile ring control unit, making one turn per month and equipped with first and second teeth, which cause two movable displaying respectively the numbers of the units and the tens.
  • the Mobile control is arranged concentrically to the needles.
  • the mobile displays are arranged side by side, inside the ring that forms the control mobile, and off-center with respect to the latter.
  • the Mobile control can be achieved by modifying a date disc classic. It is therefore possible to provide an existing template with a Big ticket display, with a minimum of modifications.
  • Such a solution involves a date at noon or 6 o'clock in the middle part of dial, with relatively modest window dimensions.
  • WO 99/13383 relates to a mechanism also comprising a control mobile performing one turn per month.
  • This mobile ensures, in in addition, the display units. It drives a display mobile dozens superimposed on the disk of the units and provided with cuts through which the numbers of the units appear.
  • the control and display mobiles dozens are off-center with respect to each other. This solution is even simpler than the previous one.
  • the display should be 6 hours or noon, and the maximum dimension of the displayed figures remains modest.
  • control and display mobiles are concentric to each other.
  • control mobiles and display are concentric to movement. It is thus possible to make a large display on the basis of an existing template, the modified date disc capable of performing the mobile function of ordered.
  • the second gear train is arranged so that the second display mobile, displaying the dozens, takes four steps per turn.
  • This mobile display is equipped with a disc marked "0" or “nothing", "1", "2” and "3".
  • the second gear train is arranged so that the second display mobile, displaying the dozens, takes five steps per turn.
  • This mobile display is equipped with a disc marked "0" or “nothing", "1", “2", “3” and "31".
  • the watch shown in FIG. 1 comprises, in a conventional manner, a box 10, a dial 12 provided with a window 14, a display of the date 16 and 18, 20 and 22 hour hands.
  • the display of the date 16 and needles 18, 20 and 22 are driven by a mounted movement in the housing that forms the box 10 and which will be partially described in 2 and 3.
  • a time-setting ring 24 makes it possible to correct the information displayed.
  • FIGS. 2a and 2b The movement, shown in plan in FIGS. 2a and 2b, is shown in section respectively along the lines AA and BB in Figures 3a and 3b.
  • a basic structure 26 schematically illustrated and formed of a frame carrying a source of energy, a time base, a cog wheel turning synchronism with the time base, and mechanisms, setting time controlled by the crown 24, and the date of the month causing the display 16.
  • the cogwheel consists of movers arranged at the center of the movement and equipped trees 28, 30 and 32 for respectively carrying the needles 18, 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 leads, in a manner known, a disk in place of mobile control 36 and making a tour in a month. It is provided with two toothings 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 structure of base 26 by means of screws not shown and extending over most of its area.
  • Plate 38 carries two gear trains 40 (FIG. 3b) and 42 ( Figure 3a) respectively engaged with the teeth 36a and 36b.
  • the plaque 38 is provided, in its central part, with a concentric barrel 38a 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 units of the date, and a pinion 44b engaged with the gear train 40 and on which is fixed the disk 44a.
  • 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 engaged with the gear train 42, and on which is fixed the disc 46a.
  • the numbers of teeth of the pinions 44b and 40c are chosen so that that, for a quarter turn of the pinion 40c, the pinion 44b makes a tenth of tower. In this way, at each step of the control wheel 36, and in the as the toothing 36a has a pin, the wheel 40a makes a quarter of turn and pinion 44b a tenth of a turn, which corresponds to the passage of a number of units to the next.
  • the tooth numbers of the pinions 46b and 42c are chosen so that that for a third turn of the pinion 42c, the pinion 44b makes a quarter of tower. In this way, at each step of the control wheel 36, and in the as the toothing 36b has a pin, the wheel 42a is one third of turn and pinion 46b a quarter turn, which corresponds to the passage of a numbers from tens to the next.
  • the wheels 40a and 42a and the references 40d and 42d are respectively pivotally mounted on the plate 38 by means of pins 48, 50, 52 and 54.
  • the pins of the teeth 36a are arranged in a circle on the disc ring 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.
  • Wheel 40a is finds at a first level, higher, chosen so that his board 40b is engaged with the toothing 36a, but does not come into contact with the tooth 36b.
  • Wheel 42a is at a second, lower level, the cutouts that includes its board 42b being engaged with the toothing 36b.
  • control mobile 36 drives the disks 44a and 46b through the gear trains 40 and 42. It is well understood that the records must be driven in a sequence such that the tens change with each passing from 9 to 0 units and that the display changes from 31 to 1 at the end of each month.
  • Figure 4 shows more precisely how this sequence is defined.
  • 4a is represented the disk of the tens 46a and in 4b the disk of the units 44a.
  • Part 4c has a table form with, in the first line, the date displayed with which is associated a position of the control wheel 36, in second line the displayed tens, in third line the structure of the teeth 36b, in fourth line the units displayed and in fifth line the structure of the toothing 36a.
  • the tens disk 46a as shown in 4a, comprises a portion central and four arms, each of them bearing a number, the sequence 0, 1, 2 and 3.
  • the disk 46a must jump when passing from 9 to 10, from 19 to 20, from 29 to 30 and from 31 to the action of the teeth of the teeth 36b represented on the third line of the table 4c.
  • the toothing 36b comprises four pins arranged so as to ensure the drive 46a drive at each change dozen.
  • the disk of the units 44a shown in 4b must jump every day except when from the 31st to the 1st. That's why, as we can see on the 5th row of Table 4c, the toothing has thirty pins and a space between the pins respectively providing the passage from 30 to 31 and from 1 to 2. In other words, because of this space, the disk of the units 44a does not jump not when going from 31 to 1 st.
  • FIG. 5 represents, according to the same structure as that of FIG. display variant in which the disk of the tens 46a has five indications, namely 0, 1, 2, 3 and 31.
  • the toothing 36b comprises five pins respectively ensuring the jump of the disc 46a during the passage 9 to 10, 19 to 20, 29 to 30, 30 to 31 and 31 to 1.
  • units 44a disc it can be driven during the passage from 30 to 31. It can also be when going from 31 to the first, as shown on this figure.
  • pinions 44b and 46b are advantageously positioned at means of jumper cooperating with their teeth. These are not however not shown, to avoid overloading the drawing.
  • control mobile 36 and the mobiles 40 and 42 are concentric with each other and with the shafts bearing the needles hours, minutes and seconds. It is also possible to realize a mechanism in which the control wheel is off-center compared to the movement.
  • Mobile displays are here too concentrically to the control mobile. In this case, the display is no longer small, but still interesting. These mobiles can be concentric to a shaft carrying a complementary display needle, indicating, for example, the second.
