  • a tourbillon also called a "rotating cage”
  • a tourbillon is a watch complication, added to the escapement mechanism, intended to improve the precision of mechanical watches by counterbalancing the disturbances of the isochronism of the resonator due to the Earth's gravity.
  • the fundamental criterion which marks a tourbillon, in comparison with a carousel in particular, is the presence of a fixed gear train on which the tourbillon cage meshes.
  • the tourbillon cage is rotatably mounted between two fixing points.
  • Gravity is also taken into account to compensate for any disturbances in the isochronism of the resonator.
  • the escapement is coupled to the resonator. It interacts with it once or twice per oscillation period.
  • the angle traveled by the resonator during the interaction is called the lift angle.
  • the rest of the resonator's path is called the additional angle or arc.
  • the resonator can be in contact with the escapement (rubbing rest escapement) or without contact (free escapement).
  • the escapement performs two main phases, which are the release (or counting) and the impulse (or maintenance).
  • the jumping second is intended to display the second in steps of a whole second, which corresponds on a 60-second dial to 6° of angle per second.
  • This jumping second is often associated with constant force mechanisms that take advantage of the particular construction of this jumping second.
  • Dead second or fixed second mechanisms also approach these constructions with the particularity of being able to stop the second at will like a chronograph.

  • a constant force device for a watch, with dead seconds.
  • This device makes it possible to move an axis of a mobile on a lever controlled by an energy storage spring, which tends to pivot the lever.
  • the device comprises a pinion of a first seconds wheel of the movement, which meshes with a setting wheel pivotally mounted on this lever, and which meshes with the pinion of a second seconds wheel defining the mobile.

  • FIGS. 3a, 3b and 3c represent three different embodiments of the flexible guide 4, which can be fixed on the one hand under the fixed second wheel SFA 2, and on the other hand to a support of the movement, such as a plate. Such embodiments allow for higher torques and better axial support. These three embodiments are also different from the embodiment shown in Figures 1 and 2 and described above.

  • each flexible guide 4 can be in the form of a flat plate, in the thickness can be chosen substantially equivalent to the thickness of the central portion of the fixed second wheel SFA 2.
  • FIG 4 represents as a complement another schematic embodiment of a traditional mechanical watch movement with the finishing gear and the force control mechanism according to the invention. Certain elements already described with reference to the Figures 1 and 2 are found in this embodiment of the traditional movement, which does not include a tourbillon. But there is an accumulation of energy by a flexible guide 4 with crossed blades 4a connected to a stop member 3 connected to a crown 32 rotatably mounted on the fixed second wheel SFA 2.
  • the flexible guide 4 comprises a fixed base portion, which can be fixed by screws 44 on a watch movement support, and a movable portion which can be directly the crown 32 linked to the stop member 3.
  • the elastic blades 4a are fixed for example by weld points 34 to the crown 32. In this case as previously indicated, the flexible guide 4 must rotate the fixed second wheel SFA 2 with the stop member 3 in the counterclockwise direction (SIAM) in the stopping phase of the movement.
  • SIAM counterclockwise direction
  • the two phases can again be specified, which are on the one hand the stopping phase and on the other hand the jumping phase.
  • the stopping phase the finishing gear 5, 8, 9, 10 is locked by the support of a tooth of the blocking element 7 against the stopping member 3.
  • the escapement wheel 11 is driven by the fixed second wheel SFA 2 counterclockwise (SIAM) by the action of the flexible guide 4 on the stop member 3 linked to the fixed second wheel SFA 2.
  • the stop member 3 is moved to release the finishing gear.
  • the second pinion 5 rotates 6° clockwise (SAM) and drives the crown 53 via the satellite wheels 51, 52 also clockwise, which also allows the flexible guide 4 to be re-armed.
  • SAM 6° clockwise
  • the stop member 3 re-locks the finishing gear for a new operation in the stopping phase to maintain the operation of the escapement mechanism linked to the oscillator.
  • Satellite wheels 51, 52 are further mounted in connection with the second pinion 5 coaxial with the second wheel 2.
  • the stop member 3 may be an arcuate plate 3 pivoting about an axis and driven by the flexible guide 4 in this embodiment.
  • the stop member 3 is in contact with a tooth of a blocking element 7, which comprises in a central portion an axial blocking pinion 8 for driving the intermediate wheel 9 having peripheral teeth.
  • the blocking element 7 may comprise several teeth on its periphery to come into contact with the stop member 3 in the stop phase.
  • the blocking element 7 is released to rotate through an angle of 120° defining the second jump, as there are 3 blocking teeth.
  • the escape wheel 11 is driven by the fixed second wheel SFA 2 via its coaxial escape pinion 12 meshing with a toothing on the periphery of the fixed second wheel SFA 2.
  • this accumulated energy is supplied to the finishing gear for the jump of the second.
  • the middle wheel 10 driven by the intermediate pinion 19 of the intermediate wheel 9 has a toothing on the periphery to mesh with the coaxial second pinion 5 for the jump of the second.
  • a large middle wheel 21 has a toothing in periphery to mesh with a coaxial pinion of average 20.
  • the arrangement by the differential with the satellite wheels 51, 52 and the crown 53 makes it possible to rearm the flexible guide 4 of the SFA to find itself again in the stopping mode with the stopping member 3 blocking the blocking element 7 by one of its teeth.
  • the mobile or second wheel can be pivoted on a ball bearing carried by the plate.
  • FIG 5 shows a cross-section from bottom to top of the mechanism in the centre of the tourbillon as partly shown above with reference to the figure 1 or to the figure 2 . It is especially noticeable in this figure that the second pinion 5 is the axis of the tourbillon cage 15.
  • the fixed second wheel SFA pivots concentrically to the tourbillon axis without touching it thanks to the flexible blade guide system holding it in position.
  • the tourbillon cage 15 encloses the escapement mechanism with the escapement wheel 11, the Swiss anchor 13 and in connection with the oscillator 14 which is the balance spring.
  • the fixed seconds wheel SFA 2 meshes with the escapement pinion 12, which means that when the tourbillon cage 15 rotates every second, a rotation is also carried out for the escapement mechanism linked to the oscillator and also the fixed seconds wheel SFA 2.
  • the flexible guide 4 is fixed to the fixed second wheel SFA 2.
  • at least one fixing means 27 in or through the openings 17 is thus provided to fix the fixed second wheel SFA 2 on the movable portion of the flexible guide 4 as previously indicated.
  • These fixing means 27 are preferably material extensions of central portions of the second wheel 2 so as to be force-fitted into the openings 17 of the flexible guide 4.
  • These material extensions 27, as well as a border around these material extensions, come directly from the material precisely with the rest of the second wheel to form only one piece.
  • a finger-shaped edge portion 3b of the rake 3 is freely disposed inside a guide housing between two teeth of a cam 6 visible at figure 2 . Since the cam 6 is fixed integrally with said fixed second wheel SFA 2 near its center, this makes it possible to drive in rotation the rack 3, which on the other hand comprises the blocking pallet 3a for blocking the whip 7 in a stop mode.
  • the whip 7 further comprises an axial blocking pinion 8, which can be rotated upon release of the whip 7 in the jump mode. All the other elements have already been explained above and will not be repeated again.
  • the mechanical movement can be a traditional mechanical movement with a fixed second wheel SFA also connected to drive or maintain the escape wheel with the oscillator in a stop phase.
