  • the tourbillon, or the carousel respectively is driven by the caliber going train and rotates on a ball bearing as seen in picture 3 , or between two drafts.
  • the operation of the invention is more particularly described for the transition from a rest position T1, in which the oscillator is free, to a position T2, in which the oscillator is blocked.
  • the control member can thus be a conventional time-setting control stem.
  • the stop wheel 1 comprises teeth cut out and oriented so as to be able to interact with a control member, which is a mechanism external to the tourbillon, or respectively to the carousel, during the transition from T1 to T2.
  • a control member which is a mechanism external to the tourbillon, or respectively to the carousel
  • the shape of the teeth on the periphery of stopper wheel 1 is such that it allows the external mechanism to hook into one of the teeth regardless of the position of stopper wheel 1, and to rotate it at a certain angle.
  • This stop wheel 1 is positioned in rotation by the stop wheel bridge 2, and makes its play between the stop wheel bridge 2 and the cage wheel 3.
  • the stop wheel 1 carries the pin d stop 4.
  • the external mechanism comprising the control member catches in a tooth of the stop wheel 1 and the rotates through a certain angle.
  • the elastic element 5, in particular the stop spring, which holds the stop wheel 1 in place via the stop pin 4 is then moved into the path of the stop cam 6.
  • the oscillator 200, in particular the balance-spring 7 is stopped and can then only be in a preferential position to restart later when released the system, since the oscillator 200 has been stopped in a position remote from its neutral point, and the torque is sufficient to ensure restarting.
  • the mechanism illustrated in the figures comprises a coaxial escapement mechanism 700, which comprises a retainer 202 which is here a coaxial anchor, a coaxial escapement wheel 204, an inter-exhaust wheel 201, all pivoted between the lower cage bridge 11 and an exhaust bridge 203.
  • the figure 6 shows the cooperation of the ellipse of the double plate 71 with the fork of the coaxial anchor, the figure 8 , at T2, shows that in the stop position, the shape of the stop cam 6 necessarily imposes a relative position of the double plate 71 and of the stopper 202 distinct from neutral.
  • the external mechanism also causes a tension on the cage 10, which immobilizes the latter, and cuts off the arrival of the torque in the escapement.
  • the oscillator 200 is not necessarily centered on the cage axis D, it can be offset.
  • the stop cam 6 is kinematically connected by at least one reference to the inertial mobile of the oscillator 200, and the stop can be made on the reference, this reference is however not essential.
  • the elastic element 5 can be placed at any place which allows it to cooperate with the stop cam 6 integral with the balance beam not concentric with the cage, an adequate arrangement of the spring constituting the elastic element 5 is sufficient, in another variant, to act directly on the cam integral with a balance wheel that is not concentric with the cage.
  • the device according to the invention thus comprises a stop-cage with stop wheel, which has the advantage of being included in the tourbillon cage, or carousel as the case may be, which carries it, which makes it possible to avoid consumption of space within the watch movement.
  • This mechanism with integrated stop wheel is compact, its manufacture is based on standard technologies, and its cost is therefore moderate.
