Definitions

  • the present invention relates to the field of watchmaking. It relates, more particularly, to an escapement mechanism comprising a balance wheel, an escapement wheel pivoting under the effect of a driving torque, and an anchor intended to cooperate on the one hand with the balance and on the other hand , with the escape wheel.
  • the invention also relates to a tourbillon mechanism provided with such an exhaust.
  • the tourbillon is a rotating regulating system well known to those skilled in the art. It is known that, when the escapement of a mechanical watch is in a vertical position, the inevitable imbalances of the balance and spiral generated by the earth's gravitation cause gait deviations. The aim of the vortex is to compensate for these variations by making the pendulum take, in the case of a vortex with a single axis, all the vertical positions.
  • a tourbillon is generally composed of a usual escapement mechanism comprising a rocker arm, an escape wheel and, in the case of an anchor escapement, an anchor. These elements are mounted in a rotating cage suspended between two pivot points, which may be located on the plate and the bridge bar or on the cage bridge and the bridge bar.
  • the cage functions as the second mobile. It carries, on its axis, a pinion of second and is driven by the average wheel.
  • the role of the exhaust is conventional. The force is transmitted from an exhaust pinion coaxial with the escape wheel, this pinion meshing, in the manner of a satellite, with a wheel of second fixed, solidary of the plate.
  • the axis of the balance must be perfectly coaxial with that of the cage.
  • the present invention aims to provide an original solution in the way the exhaust is arranged in the vortex cage. As a result, a new type of exhaust is also proposed.
  • the invention relates to an escapement mechanism comprising a balance wheel, an escapement wheel pivoting under the effect of a driving torque, and an anchor intended to cooperate on the one hand with the balance and, d on the other hand, with the escape wheel.
  • the anchor is made in two parts, each pivotally mounted perpendicularly one with reference to the other. A first of the two parts cooperates with a first of its ends with the escape wheel. The second of the two parts cooperates with a first of its ends with the pendulum. The second ends of the first and second parts of the anchor cooperate together discontinuously to kinematically connect the escape wheel and the balance.
  • the invention also relates to a tourbillon mechanism comprising a cage provided with pivoting means to be pivotally mounted with reference to a frame, the vortex bearing an exhaust as defined above.
  • a vortex is a rotating regulating system, in which an escapement mechanism comprising a rocker 10 associated with a spiral spring 11 and an escape wheel 12, is mounted in a cage 14 pivoted on an element fixed of a watch movement.
  • the escapement also includes an anchor 16, cooperating with the balance 10 and with the escape wheel 12 by pallets.
  • the cage 14 comprises an upper bridge 14a and a lower bridge 14b, interconnected by pillars 16.
  • the rocker 10 is pivotally mounted between the two bridges 14a and 14b, the upper bridge 14a being capable of receiving a cock 18 and a shockproof system 20, well known and need not be further described.
  • the lower bridge 14b is provided, on its outer periphery, with a toothing 22 and takes the form of a wheel, intended to be kinematically connected to the work train of the movement in which the vortex takes place, to receive the torque.
  • motor provided by a cylinder, not shown.
  • the cage 14 is pivotally mounted by a support 24.
  • the latter comprises a pivot zone 24a, intended to ensure the connection with the movement of the frame.
  • the pivot zone 24a is arranged to be mounted on the frame by means of a ball bearing.
  • the pivot zone 24a is oriented parallel to the bridges 14a and 14b forming the cage, so that the axis of rotation of the cage is perpendicular to the plane of the bridges 14a and 14b.
  • the pivot zone 24a is located outside the cage 14, that is to say that it is not between the two bridges 14a and 14b.
  • the pivot zone 24a is extended by an extension 24b, whose general direction is perpendicular to the pivot zone 24a, and ending inside the cage 14 by a fixing portion 24c. This makes it possible to secure the cage 14, typically the lower bridge 14b, and the support 24.
  • the end of the extension 24b located in the cage 14 also has a return 24d, oriented parallel to the bridges 14a and 14b, the role will appear later.
  • the escape wheel 12 is mounted on the support 24, more particularly on the extension 24b, along an axis perpendicular to the axis of rotation of the balance 10 and the cage 14.
  • the axis of the escape wheel 12 is located outside the cage 14. In the example illustrated, the escape wheel 12 is entirely located outside the cage.
  • the escape wheel 12 is secured, on its axis, an exhaust pinion 26, meshing with a fixed toothing 28 to ensure the rotation of the cage.
  • meshing between the exhaust pinion 26 and the fixed toothing 28 is made by means of a conical toothing.
  • the invention proposes to use an anchor 16 in two parts.
  • a first portion 16a cooperates with a first of its ends with the escape wheel 12, while the second part cooperates by a first of its ends with the rocker 10.
  • the second ends of the first 16a and the second 16b parts of the anchor cooperate together discontinuously to kinematically connect the escape wheel 12 and the rocker 10.
  • the first part 16a of the anchor is provided, at its first end, with a first and a second arm 30 each provided with a pallet 32 to cooperate with the escape wheel 12.
  • the first part 16a of the anchor comprises a first fork 34, with which cooperates the second part 16b of the anchor, as will be seen below.
  • the first part 16a of the anchor is similar to a conventional Swiss anchor. It is pivotally mounted on the extension 24b of the support 24, its axis being located outside the cage.
  • the second part 16b of the anchor comprises, at its first end, a second fork 36 with which the rocker 10 cooperates in a conventional manner, and at its second end, a finger 38 cooperating with the first fork 34. It is pivotally mounted to inside the cage, between the return 24c of the support and the lower bridge 14b.
  • the finger 38 takes place inside the first fork 34 and cooperates with it like a plateau pin cooperating with a fork of an anchor in a Swiss lever escapement of the state of the technique.
  • the second part 16b of the anchor behaves similarly to a conventional anchor, cooperating with the plate pin of the balance 10 at each alternation.
  • the finger 38 cooperates with the first fork 34 of the first portion 16a, as if it were a plateau pin, either to clear the escape wheel 12 or to transmit the It should be noted that the person skilled in the art will be able to define by appropriate tests whether the finger 38 should behave freely or in a rubbing manner, that is, if the finger 38 remains in contact with the first fork 34 or not during the rest phases.
  • stops in order to perform pull functions, these stops being able to be arranged to cooperate with one and / or the other of the parts of the anchor 16.
  • the different zones of the anchor intended to be in contact with each other, particularly the finger 38 of the second portion 16b and the first fork 34, are made of materials inducing little friction, whether traditional materials, such as rubies, especially for the finger, or more recent materials, such as silicon or other.
  • the pivoting functions of the cage and support for the escape wheel and the first part of the anchor can be dissociated, and the support functions can be fulfilled by structures mounted on the cage.
