  • the invention also relates to an anti-gallop mechanism for a watchmaking member comprising at least one spiral spring with a blade wound in a plurality of turns, of which, at a first end, an inner turn is secured to a coaxial shell -spiral with respect to a pivot axis, and at a second opposite end an outer turn is integral with a fastening element.
  • the invention also relates to a watch movement comprising a balance spring-balance resonator regulating member comprising at least one anti-gallop mechanism according to one of the preceding claims, and wherein said at least one spiral spring is mounted on an axis of a swinging pendulum between a plate and a flange.
  • the invention also relates to a method of manufacturing an anti-gallop mechanism comprising a first step: providing a substrate comprising an upper layer and a lower layer of silicon-based materials.
  • the invention relates to the field of watchmaking regulating bodies, and more particularly the pendulum spirals.
  • the exhausts In mechanical watches, the exhausts must meet several safety criteria.
  • One of the safeties, the anti-gallop system aims to prevent the angular extension of the balance beyond a normal angle of rotation.
  • Such an anti-gallop system makes a limitation of the swing angle of a rocker during excessive acceleration, especially during shocks. It is essential for certain types of exhaust, especially exhaust relaxation.
  • Such an anti-gallop mechanism must be able to act in both directions of pivoting of the balance, that is to say both in extension and contraction of the spiral.
  • the EP Patent 1 801 668 B1 on behalf of MONTRES BREGUET SA proposes a system whose structure is characteristic in that it includes a pinion mounted on the balance shaft. This pinion meshes with a toothed wheel whose at least one spoke abuts against a fixed stop if the rocker is driven beyond its normal angle of rotation. This mechanism, however, has an influence on the inertia of the pendulum, and can disrupt its oscillations. The gearing it contains generates friction which affects the efficiency and can also disturb the control system.
  • a system described in the European patent application EP2450756 A1 in the name of NIVAROX-FAR SA uses a platform integral with the balance that guides an ankle into a spiral-shaped groove. During abnormal oscillations, the ankle, integral with a pivoting arm, abuts and abruptly limits the oscillation. The friction inherent in this mechanism induces disturbances of the pendulum throughout its oscillations.
  • the present invention aims to solve these problems of the prior art, by not disturbing the inertia of the balance and limiting its angular travel in both directions of rotation.
  • the invention proposes to combine the advantages of the mechanisms described by the patent EP 1 666 990 A2 , and by the European patent application 101899987 , and to propose a reliable solution, with a low number of components, and achievable achievement with technologies related to the manufacture of pendulums and spirals made of micro-machinable materials.

  • said finger comprises at least one feeler, which develops in a direction preferably substantially parallel to said pivot axis, substantially perpendicular to a plane in which said turns extend.
  • the invention also relates to an anti-gallop mechanism for a watchmaking member comprising at least one such spiral spring with a blade wound in a plurality of turns, at a first end of which an inner turn is secured to a coaxial shell spiral spring relative to a pivot axis, and at a second opposite end an outer turn is integral with a fastening element, characterized in that at least one said turn of said spiral spring comprises at least one finger integrally mounted of said at least one turn and movable without contact, during contraction or normal extension of said hairspring, in a race limiting channel which comprises a flange of said anti-gallop mechanism, and said channel being configured to limit the stroke of said finger relative to said pivot axis when the pivot angle printed at said ferrule is greater than a determined nominal value.
