Definitions
- the present invention relates to a calendar device intended for a timepiece, particularly for a wristwatch.
- An object of the invention is therefore to propose a calendar device, particularly for displaying a large date, intended to be integrated into a movement of a timepiece, particularly of a wristwatch, improved by compared to known devices, that is to say being of a reduced thickness construction, so as not to significantly increase the thickness of the movement, respectively of the timepiece, respectively of the watch- bracelet.
- a calendar device for displaying a large date as described in claim 1.
- the figure schematically shows a portion of a movement 1, in which there is in particular the hour wheel 10 acting by means of the gear train 11 and 12 on a date wheel 13 making one revolution for 31 days.
- a jumper 14 ensures the angular position of the date wheel 13.
- This internal date mobile 2 consists of a crown, comprising an internal toothing 20 and two superimposed planks 21 and 22, each comprising an external toothing respectively 210 and 220.
- the internal date mobile 2 also performs one revolution for 31 days, the outer toothing 210 of the board 21 driving a pinion unit date 4 while the outer toothing 220 of the board 22 drives a pinion ten date 5.
- a set of jumps 6 ensures the relative angular positions of these last two gables.
- the pinions 4 and 5 drive, in known manner, directly or via sets of complementary gears, the display disks of the units and dozens of a large date.
- the number and arrangement of the teeth for each of the boards 21 and 22 as well as for the pinions 4 and 5 are generally known in the art.
- the date correction device 7 shown here in the normal operating position, comprises a rod 70 which, when it is pulled out by a notch, moves the sliding pinion 71 which then engages on the date change reference 72.
- the latter via the date change mobile 73 acts on the internal toothing 20 of the internal calendar mobile 2.
- the gear train between the sliding pinion 71 and the date change mobile comprises a friction device allowing not to transmit an opposing torque to the gear train located upstream of the date wheel 13.
- this friction device is mounted on the date change mobile 73.
- this mobile internal date 2 comprising an internal toothing and two superimposed boards with external toothing, each acting for the control of a particular display, respectively units and tens of a large date, the thickness of at least one gear wheel, which makes it possible to reduce the thickness of the movement, respectively of the timepiece or of the wristwatch compared to those existing which display a large date.
