Definitions

  • the present invention generally relates to mechanical watch movements in which the portion of the finishing train which kinematically links an intermediate wheel to the escape wheel is mounted on a rotary platform which also carries the escapement and the balance, said platform shape being further driven by the movement to rotate about the axis of the intermediate wheel at a speed different from the speed of the intermediate wheel.
  • the patent document CH 7965 in particular describes such a movement with reference to drawings, one of which is reproduced in the figure 1 , attached to this document.
  • the described movement comprises a finishing which has been shown only the last two mobiles. This is the mobile formed by the average pinion and the average wheel (respectively referenced G and H), and the mobile formed by the pinion and the second wheel (respectively referenced A and C).
  • the document specifies that the second wheel (or intermediate wheel) C causes the exhaust (not shown) in a known manner.
  • the exhaust and the beam E are mounted on a platform F.
  • the platform F has on its underside a thick cylindrical pin B which is inserted to rotate in an opening of a board P.
  • the cylindrical pivot B is hollow and is shaped so as to pass the axis of the second mobile, so that the platform F and the second wheel rotates about the same axis.
  • the average gear G is designed to drive the platform F in rotation, via a wheel D, pierced in the middle and screwed to the platform, concentrically to the axis of rotation thereof.
  • the average wheel H is driven in a fairly conventional manner at the speed of one revolution in 7 1 ⁇ 2 minutes.
  • the average G pinion has seven times less teeth than the D wheel with which it engrains, the platform F thus performs a turn every 52 1 ⁇ 2 minutes.
  • the pinion of second A has 7 1 ⁇ 2 times less teeth than the wheel of average H.
  • the pinion of second A therefore classically performs exactly one revolution per minute.
  • the frequency of the beam E must be decreased about 2% to account for the speed of platform F.
  • An object of the present invention is therefore to provide a watch movement equipped with a carousel that has the same aesthetic qualities as a tourbillon. It achieves this goal by providing a watch movement according to claim 1.
  • the cage when the movement is running, the cage rotates at a speed of one revolution per minute.
  • the second wheel of the carousels of the prior art also performs one revolution per minute.
  • the escape wheel would not be driven.
  • the speed of the second wheel is not one revolution per minute.
  • This wheel is not strictly speaking a wheel of seconds, but a false-second wheel or, more simply, an intermediate wheel.
  • the speed of this intermediate wheel is not one revolution per minute, it can not be used to carry the seconds indicator of a timepiece.
  • the cage may advantageously be visible on the dial side and itself bear means for indicating the seconds.
  • the drive train of the cage of a carousel which is represented in figures 2 and 3 , is a cogwheel type finishing.
  • it comprises a center wheel 3 driven by a barrel (not shown) and conventionally one turn per hour.
  • the axis 5 of the center wheel is intended to carry a minute hand.
  • the wheel also comprises a moving average comprising a pinion of average 7 and a wheel of average 9, and a carousel wheel 17 integral in rotation with the cage of the carousel 16.
  • the carousel wheel 17 is driven indirectly by the wheel of average via two intermediate mobiles, namely a first intermediate mobile formed pinion 11 and the wheel 13 and a second intermediate mobile referenced 15 and serving as a reference.
  • the mobile 11, 13 is hereinafter called "mobile inter second".
  • the carousel 16 carries the balance 19 and the exhaust mechanism.
  • the escape mechanism is of the conventional type. It comprises in particular an escape wheel 27 which is visible in particular on the figure 2 (the escape mechanism is not represented in the figure 3 ).
  • the figures 4 and 5 represent the cogwheel that connects the barrel (not shown) to the escape wheel.
  • figures 4 and 5 is also of the finishing type and shares some of his motives with the wheels of figures 2 and 3 .
  • the gear train driving the exhaust comprises the center wheel 3, the average wheel 7, 9, and the escapement consisting of an exhaust pinion 25 and the escape wheel 27.
  • the exhaust pinion is driven indirectly by the average wheel 9 via an intermediate mobile formed pinion 21 and the wheel 23.
  • the pinion 21 and the wheel 23 are respectively called hereinafter pinion wheel and "false second ".
  • one of the mobiles of the exhaust drive train is arranged to rotate coaxially with the carousel wheel 17 and thus also with the cage of the carousel 16.
  • the false second mobile 21, 23 which coaxially rotates with the carousel.
  • the escapement 25, 27 and the balance 19 are mounted in the cage 16 and thus rotate with it.
  • the gear ratio between the average pinion 7 and the center wheel 3 is 11 1 ⁇ 4.
  • the gear ratio between the false second pinion 21 and the average wheel 9 is 10 2/3. It can therefore be calculated that the false second wheel rotates 120 times faster than the center wheel.
  • a single mobile separates the false second mobile 21, 23 from the center wheel 3. Under these conditions, the false second wheel 23 rotates in the same direction as the center wheel, and therefore also rotates in the same direction. meaning that the carousel cage.
  • the carousel cage rotates at a speed of one revolution per minute.
  • the center wheel does one revolution per hour.
  • the speed of the axis 5 of the center wheel is therefore adequate to carry a minute hand.
  • the false second wheel 23 accomplishes two revolutions per minute. This last wheel rotating in the same direction as the cage 16, it follows that in the present example, the speed of the false second wheel 23 relative to the cage is one revolution per minute.
  • the arrangement of the cage is conventional.
  • This cage is pivotally mounted between the bearing 31 of the cage bridge 33 and the bearing 35 of the barrel bridge 37.
  • figure 5 allows to appreciate another feature made possible by the present invention.
  • the balance 19 is arranged coaxially with the cage of the carousel 16.
  • the balance shaft extends in the extension of the mobile (false) second 21, 23, between the dial (not shown) and the latter. It will be understood that, under these conditions, it is problematic to extend the axis of the second mobile to bring to it a visible needle dial side.
  • the figure 7 represents a carousel "steering wheel” which is an alternative embodiment of the carousel of the previous figures. According to this variant, the wheels and the escapement are identical to those described in relation to the Figures 2 to 6 . Comparing the figure 7 to the figure 5 it can be seen that a ball bearing 41 has taken the place of the bearing 31 in the cage bridge 33. As the bearing 31 of the figure 5 , the core 43 of the bearing shown in FIG. figure 7 is traversed by a vertical cylindrical opening for passing the false second mobile 21, 23. Also visible on the figure 7 that the outer ring of the ball bearing is fixed in the cage bridge 33 while the core 43 carries the carousel wheel 17 and thus also the cage as a whole.
  • the barrette bridge 37 ( figure 5 ) and the step 35 can be deleted.
  • the cage is mounted on a single pivot supporting it by the base.
  • the cage is completely free on the top. The carousel therefore gives the impression of flying above the movement, hence the name "flying carousel”.
  • the intermediate mobile can, as in the preceding example, turn faster than the cage in the same direction as that -this. However, it can just as well turn slower than the cage in the same direction as this one, or even turn in the opposite direction to that of the cage.
  • the skilled person will not encounter any problem to achieve these variants of carousels. Indeed, it knows how to manufacture rockers and / or escapements to regulate the rotation of a wheel at any speed different from one turn per minute. Moreover, he knows how to make escapements turning in one direction or the other. In this respect, it is worth noting that if the wheel 23 rotates in the same direction, but slower than the cage, its speed relative to the cage is negative. In other words, relative to the cage 16, the wheel 23 rotates in the opposite direction.
