Definitions

  • the present invention relates to a motion with a calendar mechanism to perpetual calendar, comprising a device of a date indicator, this device including a coach who can advance the indicator by jumping once every 24 hours.
  • This movement further comprises a device for catching up for this indicator additional catch-up steps, to take into account automatically months to 28, 29, or 30 days.
  • this movement is designed to easily fit on a movement comprising a drive device of a classic date indicator.
  • the movement according to the invention allows displaying additional daily indications, monthly and / or annual, without any modifications major to movement.
  • this mechanism is semi-perpetual, that is to say that it does not account for leap years and it requires the use of a display mechanism daily and monthly correction.
  • EP 0 052 070 discloses a perpetual drive device of the disc of date, including a cam of the months and a cam of years to achieve the required correction of the display at the end of the months of less than 31 days. This construction is complicated and can not fit on a move having a date display device traditional. In addition, this system does not allow the display of additional indications to the indication date, such as the indication of the day, months and of the leap year.
  • Swiss patent CH 169 64 describes a mechanism which does not ignores leap years and that includes a Variable slot cam system of small size dimensions, arranged between the center of the movement and its periphery. The small dimensions of this cam system does not provide satisfactory accuracy.
  • the present invention aims to remedy disadvantages of the aforementioned prior art, providing a watchmaking movement with a date perpetual, which can easily adapt to a movement already including a date display device classic, which offers great accuracy of functioning and which, in addition, allows the display additional indications to those of the date, such as the indication of the month and / or years leap and non-leap, as well as a 24h display allowing initialization after stopping the watch.
  • Motion 1 includes a calendar mechanism to perpetual calendar comprising a date disc 2 which carries indications of the dates 4. These indications appear in a window 6 of a dial, not shown.
  • Disk 2 is associated with a device 8 having drive means constituted by an elastic arm 10 integral with a wheel of 24 hours referenced 12.

  • the device 8 is designed so after the changeover to the next day, as explained above, the hook 18 emerges from the toothing 22 to allow, where appropriate, further advancement of the disk 2 to make it take one or more steps catch-up and to take into account months with less than 31 days, using a catch-up device that will be described below.
  • the training device 8 is a device classic that will not be described in more detail.
  • the movement 1 comprises a catch-up device provided with a rotary cam 26 driven at least one step every 24 hours and performing a full turn per year.
  • the cam 26 is guided in rotation, for example at the surface of the movement, by means not shown and it has a profile 28 intended to drive a feeler 30.
  • the probe 30 controls, on the one hand, the movement oscillating of a mobile equipment 32 which is provided with a ratchet system 34 for advancing the disc 2 the required catch-up step (s).
  • the probe 30 controls, on the other hand, the advancement of the cam 26 to make it perform a number of steps equal to the number of retrofit steps of the disc 2.
  • the cam 26 is driven by a gear train connected to the hour wheel 16. More specifically, the wheel of the hours 16 canon (hereinafter referred to as the hour wheel) carries a pinion 36 engaged with the wheel 38 of a first mobile. This first mobile has a finger 40 integral wheel 38. The gear ratio between the pinion 36 and the wheel 38 is such that the wheel 38 performs a turn in 24 hours. The finger 40 cooperates with the teeth a wheel 42 to 31 teeth belonging to a second mobile whose pinion 44 drives the cam 26.
  • the finger 40 is positioned at the assembly so that the latter comes into contact with the teeth of the wheel 42 after the training device 8 has allowed the jump of the disc 2.
  • the cam 26 has an annular shape surrounding the mobile equipment 32 and the training device 8.
  • the cam 26 and the hour wheel 16 have the same axis of rotation R.

  • the probe 30, which has the general shape of an anchor, includes a first arm 48 which rests, under the action of a return spring 50, on the profile 28 of the cam 26 by a lift 52.
  • the lift 52 which is in permanent contact with the profile of the cam 26, has a semi-spherical shape and is disposed in the vicinity of the free end of the arm 48.
  • This lift 52 is preferably made of ruby synthetic.
  • the probe 30 comprises a second arm 54 which is connected to the first arm 48 by a joining portion 56.
  • This second arm 54 is coupled to the mobile assembly 32 by its free end which has the shape of a fork 58 whose the teeth are engaged, in the example shown, on a pin 60 secured to the moving assembly 32.
  • the probe 30 comprises a third arm 62 extending from the joining portion 56, substantially in the extension of the first arm 48 and the end cooperates with the spring 50 to push the lifting 52 towards the profile of the cam 26.
  • the probe 30 is pivotally mounted by its junction part 56, via an axis 64, on the movement, for example on a plate (not shown).
  • the axis 64 of the probe 30 is associated with an eccentric 66 which allows the final adjustment of the lift 52 by relative to the profile 28 of the cam 26.
  • the probe 30 and the spring 50 generally extend under the cam 26.
  • the mobile equipment 32 is also associated with a mobile lever 68 which is articulated by one of his free ends on the pin 60, this lever 68 being controlled by the probe 30.
  • the other free end of the lever 68 has a spout 70 engaged with a wheel 72 to Wolf teeth.
  • This wheel 72 is secured to the wheel 44 belonging to the mobile driving the cam 26.

  • the base plate 80 extends from the center of the radial direction towards disk 2.
  • This plate 80 carries the ratchet 34 which is rotatably mounted on this plate via a pivot 82.
  • the pawl 34 consists, on the one hand, of a spout 84 intended to engage in the toothing 22 of the disc 2 and, on the other hand, an elastic arm 86 which extends above the plate 80. In this example, the arm 86 extends towards the center of the movement.
  • the pawl 34 further comprises a spring 88 acting on the beak 84 to get it into the Toothing 22 of the disk 2.
  • the spring 88 has the general shape of an L that surrounds partially pivot 82 and a branch is based against one side of the beak 84, while the other branch leans against an axis 90 secured to the plate 80.
  • the axis 90 carries a 24-hour wheel referenced 92, which meshes with a pinion 94, integral with the barrel of hours.
  • Axis 90 also carries an inertial cam 96 which is driven by the wheel 92, this inertial cam 96 periodically cooperating with the end of the arm 86 to block this arm 86 against a pin 98, also carried by the base plate 80.
  • this arrangement constitutes a locking system allowing, every two months, to block the movement of the arm 86 ratchet 34 to condemn it at the time of the jump (s) catching up.
  • this locking system maintains, in a first position, the nozzle 84 almost fixed for this spout 84 provides drive disk 2.
  • this locking system releases the spout 84 to ensure its function of ratchet, vis-à-vis of disk 2, when this disk 2 is actuated, in particular by the driving device 8.
  • the profile 28 of the cam 26 is formed of five sectors contiguous referenced I to V interconnected by recesses forming notches E1 to E5.
  • the depth notches E1 to E5 determines the radial displacement of the probe 30, and in particular the radial displacement of the lift 52 to make disk 2 perform the number of steps of catch-up required at the end of the month with less than 31 days.
  • the five sectors I to V form continuous ramps R1 to R5 extending in the counterclockwise direction. These ramps R1 to R5 extend from the bottom of a notch to the top of a next notch En + 1, from a first ray to a second radius greater than first.
  • One of the notches, referenced E3, presents a. depth greater than that of the other four notches E1, E2, E4, E5, the latter having depths equal to each other.
  • Notches E1, E2, E4 and E5 have depths such that they can move the probe 30 to order, via the mobile equipment 32, the displacement of disc 2 of a catch-up at the end of the month at 30 days (April, June, September, November), while the notch E3 has a depth such that it can make move the probe 30 to also control via the moving equipment 32, the displacement of the disc 2 of two or three catch-up steps, respectively at the end of months of 29 and 28 days (February, leap and non-leap).
  • the depth of the notch E3 is not constant.
  • the E3 notch is associated with a system referenced 100, able to vary its depth a once every four years.
  • This system 100 visible to the FIG. 13, consists of a movable flap 102 mounted at rotation on the cam 26 via an axis 104.
  • the axis 104 carries a wheel 106 making a turn every four years, this wheel being operated, at each complete rotation of the cam a quarter of a turn.
  • the system 100 cooperates once a year with a fixed finger of the movement, referenced 108. Thanks to this arrangement, the movable flap 102 can close off a once every four years the E3 notch to reduce its depth. This limits the movement of the feeler 30 so that the latter does not make disc 2 that two no catch-up at the end of the months of February leap years.
  • flap 102 has a flange which, when the flap comes once closing the notch E3, extends the length of the ramp R3 by a distance corresponding to a day.
  • the wheel 106 is held in position by a jumper 110 L-shaped, rotatably mounted with a pivot 112 which is supported by a crown 116 forming a disc of the months and solidarity of the cam.
  • This jumper 110 cooperates with a return spring 114 which acts on one of the branches of the L so that the other branch comes between two teeth of the wheel 106, this second branch having an end provided for this effect.
  • the jumper 110 and its spring 114 turn with cam 26 at the rate of one complete revolution per year.
  • FIG. 13 also shows a leap year indication device 120 which can advantageously equip the movement 1.
  • the device 120 comprises a star 122 carrying a annual indication needle (not shown), this needle being rotated on the movement 1.
  • the star 122 is maintained by a jumper spring 124, ensuring the positioning of the needle.
  • the star 122 has eight branches and is driven by two drive teeth 126 integral with the cam 26.
  • the star 122 is ordered, once a year, by both teeth to perform a quarter turn at each complete rotation of the cam. This indication is valuable for highlighting the leap year.
