Definitions

  • the invention relates to a device for momentarily stopping the operation of a mechanical watch, in particular a mechanical tourbillon watch, and preferably when the time of the watch is reset.
  • a mechanical tourbillon watch the tourbillon carriage encloses a mechanical oscillator linked to an escapement wheel.
  • the invention also relates to a mechanical tourbillon watch, which comprises a device for temporarily stopping the operation of the watch.
  • a tourbillon also called a "rotating cage”
  • a tourbillon is a horological 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 characterizes a tourbillon, in relation to 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.
  • the primary function of the tourbillon is to rotate the resonator of the watch relative to gravity at a constant speed in order to average the effects of this gravity on the isochronism of the resonator.
  • the escapement is coupled to the resonator to ensure its maintenance and to regulate the speed of rotation of the gear trains of the watch (counting). It interacts with it once or twice per period of oscillation.
  • the angle traveled by the resonator during the interaction is called the angle of lift.
  • the rest of the resonator's path is called an additional angle or arc.
  • the resonator can be in contact with the escapement (exhaust at rubbing rest) or without contact (free escapement).
  • the escapement performs two main phases, which are release (or count) and impulse (or sustain).
  • the lever-stop mechanism is controlled by the time-setting mechanism and acts on the resonator to block it in a stationary position, which interrupts the counting and stops the movement of the finishing and display gear trains. More specifically, it is a leaf spring resting on a rim of the spiral balance wheel, which constitutes the resonator. As this blade stops the balance in a random position, it is possible to stop the balance in its rest position, in this case the restarting of the balance after its release by the mechanism is not assured.
  • the patent EP 2 703 912 B1 describes a device for stopping a spiral balance wheel (resonator) mounted in a tourbillon of a mechanical watch.
  • the device comprises two stop levers each pivotally mounted on a lever pivot axis, to be able to move them from a rest position where the balance wheel and the tourbillon can rotate freely and a stop position where at least one of the levers is brought into contact with the pendulum to stop it.
  • prestressing means are provided for each of the stop levers, so that the force which is exerted on the balance thanks to the stop levers can act separately.
  • a direct action of each stopper lever separately can cause a problem to effectively stop the balance-spring during a time reset of the watch and independently of the position of the tourbillon carriage, which can complete an entire turn.
  • the patent EP 2 787 400 B1 describes a watch movement with a tourbillon and a mechanism for stopping the balance wheel.
  • the tourbillon comprises in a cage between a lower cage part and an upper cage part, the spiral balance wheel.
  • the stop mechanism comprises a stop element which is integral in rotation with the cage to come into contact with the rocker arm in a stop position, and a device for actuating the stop element.
  • the stop element may be in the form of a disk coaxial with the cage to come into friction with the balance to stop it. Long-term wear of the hairspring balance may thus occur through such a stop contact by the disc.
  • a mechanical watch in particular a mechanical tourbillon watch
  • the time of the watch is reset.
  • This invention guarantees instantaneous stopping and restarting of the tourbillon and the balance-spring which are visible through an opening of the dial of current tourbillon constructions.
  • This invention also makes it possible to guarantee a minimum winding angle of the hairspring which ensures proper functioning of the balance after its release.
  • the object of the invention is therefore to overcome the drawbacks of the state of the art by providing a device for temporarily stopping the operation of a mechanical watch, in particular a mechanical tourbillon watch, overcoming the drawbacks of the aforementioned prior art.
  • the invention relates to a device for temporarily stopping the operation of a mechanical watch, in particular a mechanical tourbillon watch, which comprises the characteristics defined in independent claim 1.
  • An advantage of the stop device lies in the fact that it comprises several levers arranged in a circle on a plate of the mechanical movement and designed to be moved together from a rest position to an active position under the simultaneous action of a organ concentric with the axis of rotation of the balance-spring or the tourbillon carriage.
  • the levers driven in rotation in the active position will push outwards the control rod of a stop lever rotatably mounted on a cage support so that one end of the lever stop comes into contact with a central cam of the balance so as to stop the mechanical movement to reset the time of the watch.
  • the arrangement of the levers which can be pivoted and mounted on the plate in a circle, makes it possible to have a control edge in an active position of the levers to actuate the stop lever for stopping the balance independent of the position of the cage of tourbillon, in the case of a watch with a mechanical tourbillon movement.
  • the levers driven in rotation in an active position on the plate can momentarily stop the movement by immobilizing the oscillation of the balance-spring and also by immobilizing the tourbillon cage mainly by the friction of the contact of the stop lever control rod on one of the levers.
  • the levers arranged in a circle will be driven in rotation to push the control rod of a stop lever inwards to block the mechanical movement during the time reset of the watch by stopping momentarily the balance-spring, and all the finishing wheels of the movement. It can be provided in this non-limiting case of six levers arranged in a circle.
  • all the levers constituted by elements with flexible blades together form a single component.
  • the control ring can be driven in rotation by the control rod so as to push the flexible blade elements into an active position to control the momentary stoppage of the operation of the watch.
  • there are no oblong-shaped openings on each lever given that it is played on the flexibility of the spring blades so as to allow all the levers to automatically return to position rest in the inactive position of the control ring.
  • the design of this mechanism can be reversed with a free position of the spring blades corresponding to the active position and a constrained position corresponding to the inactive or rest position.
  • a proposed mechanical solution of the device does not penalize the aesthetics of the tourbillon, and does not penalize the inertia of the tourbillon by making it possible to stop the oscillator.
  • the stop lever can also stop the oscillator, while the levers arranged in a circle on the plate can be used to brake the tourbillon cage. Provision may be made for a rough surface or with small teeth on the periphery of the levers to ensure better braking of the tourbillon cage.
  • levers there may be provided at least three levers or four levers arranged in a circle on the plate to be driven together in rotation by a ring connected to the levers.
  • the levers are each rotatably mounted by an axial rotation rod on the plate so as to serve as a rotation guide for the lever activation ring.

  • the invention also relates to a watch with a mechanical tourbillon movement which comprises the device for temporarily stopping the operation of the mechanical movement of the watch, and which comprises the features of independent claim 17.
  • a device for effecting a momentary stoppage of the operation of the mechanical movement, an instantaneous stoppage when passing from the normal position to the time-setting position and ensuring the restarting with a minimum amplitude of the balance when changing from the time-set position to the normal position of a mechanical tourbillon watch, in particular when resetting the time of said watch.
  • the stop device is preferably a stop lever stop device.
  • the cage encloses a resonator, which is preferably a balance-spring and an escapement mechanism, which notably comprises an escapement wheel set as explained briefly below.
  • the device for temporarily stopping the operation of the mechanical watch firstly comprises a lever stop to block the balance-spring especially when resetting the watch.
  • the stop lever rotates with the tourbillon cage, and can be activated to temporarily stop the operation of the watch by an arrangement of levers mounted in a circle on a plate of the watch movement.
  • the levers can occupy a rest position or an active position in which they act to directly activate the stop lever for a momentary stoppage of the operation of the watch and this in any position of the tourbillon cage and of the stop lever.
