Definitions

  • the present invention relates to mechanical watch movements whose energy is provided by a spring contained in a barrel. It relates, more particularly, to a mechanism indicating the power reserve of a mechanical timepiece movement with a main barrel for driving the finishing gear and at least one second barrel for training. a gear train assigned to an auxiliary function that must be provided for a specified minimum period.
  • Such a mechanism applies especially well to a chronograph mechanical watch movement displaying the hour and minute of time timed using discs.
  • the determined minimum duration is equal to the maximum measurable time.
  • the problem that arises then is that of the mechanical energy necessary to drive the discs.
  • the single barrel may indeed be difficult, which disrupts the amplitude of the oscillations of the pendulum and, consequently, the proper functioning of the chronograph wheel.
  • EP Application No. 03 405532.7 provides a solution to this problem by proposing a movement in which the discs of hours, tens of minutes and units of minutes of timed time are each driven by their own barrel.
  • the present invention aims to meet this need.
  • EP 12 60 883 discloses a watch with two barrels operating in series with display of the total power reserve.
  • the indicated power reserve is that of the cylinder having the shortest reserve.
  • the chronograph watch shown diagrammatically in FIG. 1 is intended to display, on a dial 10, in a conventional manner, the hour, minute and second of the current time by means of two central hands 11, 12 and a small hand at 9:13 am
  • the watch also displays the seconds of timed time using a central hand 14, while the indications of the hours, tens of minutes and minutes units of the timed time are provided respectively by three discs 15, 16 and 17 appearing behind windows in the dial 10.
  • a small needle 18 and a small rotating dial 19 are arranged at 6 o'clock to display the power reserve of the coin, as will be described with reference to FIG.
  • this watch has, as a base, a mechanical caliber of the chronograph type, such as that marketed by ETA SA (Switzerland) under the reference 7750. It is coupled to a complementary mechanism described in detail in document EP 03 405 532.7 above and providing driving of disks 15, 16 and 17.
  • a ring 20 is used for winding and setting time, while two pushers 21 and 22 respectively control the start and stop, and the zeroing of the chronograph mechanism.
  • FIG. 2 divided into two parts 2a and 2b, in which only the members participating in the power reserve display function are represented.
  • FIG. 2a there is shown in 23 the barrel of the base movement which is the main engine of the watch.
  • This barrel which typically has a running time of approximately 40 hours, comprises, inside its drum, a spring (not shown) provided with a sliding flange serving, when fully armed, to limit its surge.
  • Its shaft 24 carries a ratchet 25 which can be driven from the crown 20 by the winding pinion and the crown wheel (not shown).
  • the outer toothing 26 of the drum meshes with the work train (not shown) which drives the hour hands 11, minute 12 and second 13.
  • the shaft 24 carries a wheel 27 meshing with a gear 28 which itself meshes with a wheel 29 fixed to the shaft 30 of a second cylinder 31 whose drum also contains a spring slippery flange and whose running time is the one during which the chronograph function must be ensured. Typically, this walking time is 10 hours.
  • the outer toothing 32 of the drum of this barrel meshes with a gear train (not shown) which drives the display disc 17 of the minute units of the timed time.
  • the shaft 30 also carries, on the same side, a ratchet 33 which meshes with a gear train terminating in the ratchet of a third cylinder (not shown) serving to drive the display disk 16 tens of minutes of the timed time.
  • the third barrel actuates a fourth barrel for driving the display disc hours of timed time 15.
  • the shaft 30 carries a pinion 34 which meshes with a wheel 35 whose pinion 36 meshes with a wheel 37 provided with a pin 38 and carrying the power reserve indicator dial 19.
  • the wheel 37 is pivotally mounted on a shaft 39 on which the power reserve indicator needle 18 is mounted and, on the opposite side, a wheel 40 (visible in FIG 2b) provided with a circular opening 41 whose length corresponds to the time during which the chronograph function must be ensured, approximately 10 hours.
  • the shaft 39 carries, frictionally mounted, a wheel 42 which meshes with the pinion 43 of a wheel 44 whose shaft serves as a pivot to the wheel 35 and which meshes with a second pinion 45 carried by the shaft 30 of the second cylinder 31.
  • the shaft 39 carries, between the open wheel 40 and the friction wheel 42, a pinion 46 which meshes with a return 47 meshing with a wheel 48 having a circular opening 49 whose length corresponds to a rotation time of about 30 hours.
  • a wheel 50 mounted free to rotate on the shaft 51 of the wheel 48, is provided with a lug 52 which fits into the opening 49.
  • the wheel 50 meshes with a pinion 53 whose shaft 54 carries, frictionally mounted, a wheel 55 meshing, via a return 56, with a pinion 57 whose shaft 58 carries a pinion 59 meshing with the a wolf toothing with a mobile 60 which meshes with the external toothing 26 of the drum of the main barrel 23.
  • the shaft 24 raises the spring of the main barrel 23 and, at the same time, the spring of the second barrel 31 by the intermediate of the mobiles 27, 28 and 29 and the shaft 30.
  • the pinion 34 also carried by the shaft 30, drives, through the wheel 35 and its pinion 36, the wheel 37 and the power reserve indicator dial 19 which, rotating in the counterclockwise direction, that the needle 18, almost immobile, indicates an increase in the power reserve.
  • the lug 38 of the wheel 37 moves freely in the opening 41 of the wheel 40 which, therefore, does not rotate.
  • the needle 18 indicates, on the dial 19, a power reserve of 10 hours.
  • the lug 38 also comes into abutment on the end of the opening 41 of the wheel 40.
  • the wheel 40 starts to rotate under the action of the lug 38, thus driving the needle 18 at the same time as its dial 19, so that the display of the power reserve remains over 10 hours.
  • the wheel 42 being mounted frictionally on the pinion 46, it remains in a position corresponding to that of the barrel 31 with which it is connected by the pinion 43, the wheel 44 and the pinion 45.
  • the wheel 40 also drives, via the pinion 46 and the return 47, the wheel 48 whose opening 49 receives the lug 52 of the wheel 50. At the time when the reassembly reaches a state corresponding to a running time about 30 hours, this lug comes into abutment on the end of the opening 48.
  • the wheel 50 starts to rotate and, through the movable 53, 55, 56, 57 and 58 drives the pinion 59 The latter, however, because of the presence of the wolf gear 60, has no effect on the main barrel 23.
  • the drum of the main barrel 23 is the only one in action and therefore causes the display gear of the current time by its external toothing 26, which also drives the worm gear 60 which, in this direction of rotation, communicates its movement to the pin wheel 50.
  • the wheel 50 will thus rotate for about 30 hours without influencing the display of the power reserve, always 10 hours, since its lug 52 flows freely in the opening 49 of the wheel 48. After these 30 hours of operation, the lug reaches the stop on the end of the opening 49 and the wheel 48 begins to rotate.
  • the pinion 46 and the shaft 39 it begins to rotate the power reserve indicator needle 18 counterclockwise from the 10 o'clock position.
  • the second barrel 31 is inactive and the wheel 42 is therefore immobile, the movement of the needle 18 is allowed since this wheel is frictionally mounted on the shaft 39.
  • the second cylinder 31 is activated every minute and influences the indication of the power reserve. Its pinion 45 thus begins to drive, through the wheel 44, the pinion 43, the wheel 42 and the shaft 39, the power reserve indicator needle 18 which begins to move in the direction counterclockwise.
  • the shaft 39 drives the pinion 46 and the wheel 40. The latter meshes with its pinion 46 with the return 47 which drives the open wheel 48.
  • the main cylinder is still in action and drives the wheel 50 whose lug 52 will come into abutment on the end of the opening 49 of the wheel 48 after 30 hours, to which is added the time during which the chronograph mechanism has operated, because of the synchronous movement of the wheels 50 and 48.
  • the chronograph mechanism was switched on for 3 hours, the lug 52 will not come to a stop until after 33 hours.
  • the needle 18 indicates a power reserve equal to 10 hours minus 3 hours, it will arrive at zero after 40 hours of operation of the main cylinder.
  • the lug 52 also turns the wheel 48. It is then imperative to prevent the two barrels add their actions on the control of the needle 18.
  • the wheel 48 is also urged by the rotation of the wheel 42 driven by the second cylinder 31.
  • the wheels 48 and 50 are driven at the same speed and with a frost gearing equal to at least one minute (made necessary by the fact that the barrel 31 advances in steps of one minute)
  • the lug 52 of the wheel will remain in the same relative position relative to the end of the opening 49 of the wheel 48.
  • the needle 18 is thus driven without conflict between the two barrels, the same power reserve displayed corresponding to that of the main barrel.
  • the described mechanism is integrated in a watch provided with manual winding of the barrel springs. It is obvious that it can, without further, be applied to a self-winding watch.
