  • the height of the projection of the pivot pin 810 is less than the difference between on the one hand the height of the chamber 800 in the axial direction Z at the level of the pivot axis DP, and on the other hand the maximum thickness of the stop lever 2, so as to authorize the extraction of the stop lever 2 by combination of an axial movement to release the bore 820 of the pivot pin 810, and a substantially plane movement, perpendicular to the articulation pin DA, of the stop lever 2.
  • the stopping mechanism 100 further comprises, integral with the first part 21 and second part 22, a third stabilizing part 23 which is movable in the chamber 800, with at least one axial degree of freedom in a parallel axial direction Z to the main axis D.
  • the structure 500 and the second bridge 700 limit the axial travel of the third stabilizing part 23 below a maximum value CM, to ensure rotational movement of the second part 22 around the pivot axis DP, substantially plane perpendicular to the main axis D.
  • the removable articulation between the first control part 21 and the control member 210 comprises a fork 25 carried by the first part 21, arranged to cooperate with a pin 26 which the control member 210 comprises, or vice versa. , so as to authorize lateral assembly or disassembly between the first part 21 and the control member 210.
  • the elastic return means is carried by the stop lever 2, which comprises a fourth flexible part 24, arranged to cooperate in support with a lower surface 724 of the second bridge 700 to press the stop lever 2 on the structure 500.
  • this elastic return means can consist of a spring integral with the second bridge 700, or similar.
  • the fourth part 24 is not coplanar with the first part 21, the second part 22 and the third part 23, which are coplanar with each other.
  • the fourth part 24 is in one piece with the third part 23, and is not coplanar with the first part 21 and the second part 22 which are coplanar with each other.
  • the fourth part 24 is in one piece with the first part 21, and is not coplanar with the second part 22 and the third part 23 which are coplanar with each other.
  • the stop lever 2 is in one piece.
  • the stop lever 2 is a cut and folded component, and therefore very economical.
  • the invention also relates to a timepiece 1000 comprising a regulator or chronograph mechanism comprising a structure 500 and at least a first bridge 600 on either side of a mobile 1 mobile in rotation around a main axis D , and comprising such stopping mechanism 100, for triggering the stopping or releasing of this mobile 1 of the regulator or chronograph mechanism.

  • the stop lever also more commonly called stop lever, is designed so as to be removable without removing the bridge above it.
  • the cross-sectional figures help to understand the system.
  • the movement to be applied to disassemble the stop lever is broken down into two phases: an axial movement in the Z direction to release the guide stop lever at the level of the pivot axis DP, and then a plane movement in a plane parallel to that of the balance.
  • the shaft guiding the stop lever allows axial assembly/disassembly along the Z axis, parallel to the axis of rotation of the balance wheel.
  • Articulation with the upstream control mechanism is done with an articulated mechanism, such as a fork and pin allowing side disassembly, or the like.
  • the stop lever In place and prevent it from being disassembled by itself, it advantageously comprises a flexible blade resting on the upper bridge, which presses it axially downwards on the structure, in particular a plate.
  • the pallet bridge can be removed without removing the stop-second, it is not not the same on a caliber comprising a high frequency oscillator (more than 5 Hz), which requires a stop-second which acts on a heart cam on the balance in order to restart it for starting; the stop-second then passes above the anchor bridge, and the invention finds its full usefulness there.
  • a caliber with a high frequency oscillator requires such a stop-second which acts on a heart cam on the balance wheel in order to restart it for starting, this starting function being necessary due to a frequency greater than 5 Hz The stop-second therefore passes above the anchor point.
  • the invention makes it possible to avoid dismantling the upper bridge (barrel bridge, cog bridge, or other), and makes maintenance operations more economical, and guarantees the cleanliness of the mechanisms.
