Definitions

  • the present invention relates to mechanical watch movements whose energy is provided by a spring contained in a barrel. She more particularly, a mechanism indicating the reserve of walking of a mechanical timepiece movement with a barrel principal for driving the finishing gear and at least one second barrel for driving a gear train assigned to a function which must be provided for a specified minimum period.
  • Such a mechanism applies especially well to a watch movement mechanical chronograph displaying the hour and minute of timed time using discs.
  • the minimum duration determined and equal to maximum measurable time.
  • the problem that arises then is that of the mechanical energy necessary to drive drives.
  • the single barrel may, in fact, be at the pain, which disturbs the amplitude of the oscillations of the pendulum and, by therefore, the proper functioning of the chronograph wheel.
  • the present invention aims to meet this need.
  • the indicated power reserve is that of the barrel having the shortest reserve.
  • the chronograph watch shown schematically in FIG. intended to display, on a dial 10, in a conventional manner, the hour, the minute and the second of the current time using two central needles 11, 12 and a small hand at 9 o'clock.
  • the watch also displays the seconds of time timed using a central hand 14, while the indications of the hours, tens of minutes and minutes units of timed time are provided respectively by three disks 15, 16 and 17 appearing behind counters in the dial 10.
  • a small needle 18 and a small rotating dial 19 are arranged at 6 hours to display the power reserve of the part, as will be described next to Figure 2.
  • this watch has, as a base, a mechanical caliber of chronograph, such as the one sold by ETA SA (Switzerland) under the reference 7750. It is coupled to a complementary mechanism described in detail in the aforementioned EP document and providing training discs 15, 16 and 17.
  • a crown 20 is used for winding and the hour, 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, on which only the organs participating in the function are represented display of the power reserve.
  • FIG. 2a shows at 23 the barrel of the basic movement which is the main engine of the watch.
  • This barrel which has, typically, a walking time of about 40 hours, includes, inside his drum, a spring (not shown) provided with a sliding flange serving, when fully armed, to limit its surge.
  • His 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 external toothing 26 of the drum meshes with the finishing gear (not shown) which leads to the hour hands 11, minute 12 and second 13.
  • the shaft 24 carries a wheel 27 meshing with a 28 which meshes itself with a wheel 29 fixed on the shaft 30 of a second barrel 31 whose drum also contains a flange spring slippery and whose running time is the one during which the function chronograph must be ensured. Typically, this walking time is 10 hours.
  • the outer toothing 32 of the drum of this barrel meshes with a cogwheel (not shown) ensuring the drive of the display disc 17 of units of minutes of timed time.
  • the shaft 30 also carries, from same side, a ratchet 33 which meshes with a gear train leading to the ratchet a third cylinder (not shown) used to drive the disc 16 display tens of minutes of timed time.
  • the third barrel actuates a fourth barrel used to drive the display disc hours of the 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 are mounted the power reserve indicator hand 18 and, on the contrary, a wheel 40 provided with a circular opening 41 whose length corresponds to the time during which the chronograph function must be ensured, ie 10 hours about.
  • 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 for the wheel 35 and which meshes with a second pinion 45 carried by the shaft 30 of the second barrel 31.
  • the shaft 39 carries, between the open wheel 40 and the friction wheel 42, a pinion 46 which meshes with a referral 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 rotatably mounted on the shaft 51 of the wheel 48, is provided with a pin 52 taking place in the opening 49.
  • the wheel 50 meshes with a pinion 53, the shaft 54 of which is mounted frictionally, a wheel 55 meshing, via a return 56, with a pinion 57 whose shaft 58 carries a pinion 59 meshing by means of a wolf toothing with a mobile 60 which meshes with the external toothing 26 of the drum of the main barrel 23.
  • the pinion 34 also carried by the shaft 30, drives, via the wheel 35 and its pinion 36, the wheel 37 and the reserve indicator dial 19 which, turning counterclockwise, causes the needle 18, practically still, 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 dial 19, a 10-hour power reserve.
  • the ergot 38 also comes in stop 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 causing the needle 18 at the same time as its dial 19, so that the display of the power reserve remains on 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, through the pinion 46 and the return 47, the wheel 48 whose opening 49 receives the lug 52 of the wheel 50. At the moment when the winding reaches a state corresponding to a running time of approximately 30 hours, this lug comes into abutment on the end of the opening 48.
  • the wheel 50 starts to turn and, through the mobile 53, 55, 56, 57 and 58 causes the pinion 59. This, however, because of the presence of the mobile to wolf teeth 60, has no effect on the main barrel 23.
  • the drum of the main barrel 23 is the only one in action and therefore drives the display gear of the current time by its external toothing 26, which also causes the toothed gear wolf 60 which, in this direction of rotation, communicates its movement to the wheel with pin 50.
  • the wheel 50 will thus rotate for about 30 hours without influencing the display of the reserve of walk, always on 10 hours, because its lug 52 circulates freely in the opening 49 of the wheel 48.
  • the ergot 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 starts turning the power reserve indicator hand 18 counter-clockwise from the 10 o'clock position.
  • the second barrel 31 is inactive and that the wheel 42 is therefore immobile, the movement of the needle 18 is authorized since this wheel is mounted frictionally on the shaft 39.
  • the second barrel 31 is put into action every minute and influence the indication of the power reserve.
  • Its pinion 45 begins to drive, through the wheel 44, the pinion 43, the wheel 42 and the shaft 39, the indicator needle reserve of step 18 which begins to move in a counter-clockwise direction.
  • the tree 39 causes the pinion 46 and the wheel 40.
  • the latter meshes with the referral 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, plus the time during which the chronograph worked, because of the synchronous movement of the wheels 50 and 48.
  • the chronograph mechanism was triggered during 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 less 3 hours, it will arrive at zero after 40 hours of operation. main barrel.
  • the wheel 48 is also requested by the rotation of the wheel 42 entrained by the second cylinder 31.
  • the wheels 48 and 50 are driven at the same speed and with a discussion of gears equal to at least one minute (made necessary by the fact that the barrel 31 advance in steps of one minute), the pin 52 of the wheel will remain in the same relative position with respect to the end of the opening 49 of the wheel 48. Thanks to these provisions, 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 with winding manual cylinder springs. It is obvious that he can, without applied to a self-winding watch.
