Definitions

  • the invention relates to a clockwork movement, comprising a mechanism comprising at least one inertial element arranged to oscillate or pivot about a first axis of pivot relative to a structure of said movement, and arranged to cooperate directly or indirectly with at least a mobile energy distributor pivoting relative to said structure about a second pivot axis parallel to or coincident with said first pivot axis and subjected to a torque exerted by at least one energy source.
  • the invention also relates to a watch comprising at least one such movement.
  • the invention relates to the field of watch mechanisms, in particular those that are sensitive to the movements of the user or the device that carries them, and whose operation is sensitive to accelerations related to the circumstances of the worn, such as flights, sudden movements or falls.
  • the invention finds a particular interest for providing protection to resonators, regulators, or drive members.
  • the escapement wheel In a classic Swiss-anchor escapement mechanism, the escapement wheel has a variable rotational movement: at each alternation, it is initially blocked by the anchor, then briefly accelerated by the torque applied by the barrel, and finally blocked again. These long phases in locked position give this type of exhaust a great robustness to rotational accelerations due to the worn.
  • Some escapements such as the Clifford escapement, or the direct synchronization magnetic escapement, require the escape wheel to rotate at a near constant speed, with no downtime.
  • This continuous rotation has many advantages, in particular an increase in the energy efficiency of the exhaust, because it is no longer necessary to accelerate the escape wheel at each alternation.
  • these systems can become sensitive to rotational accelerations due to the wear, because the escape wheel necessarily has a certain inertia. In one case particularly disadvantageous, an acceleration due to the bearing against the normal rotation of the wheel can stop temporarily or permanently if the exhaust is not self-starting.
