摘要： A shock absorber device for an arbor of a timepiece element includes a support including a base cup surmounted by a peripheral rim delimited, opposite the cup, by an upper surface and including an outer wall, the cup and the rim defining together a housing. The shock absorber device further includes a pivot module extending along an axis, the pivot module being arranged inside the housing and being able to cooperate with the arbor. The shock absorber device further includes fastening device including a peripheral shoulder extending from the rim towards the axial center of the cup, and elastic device being arranged between the pivot module and the shoulder to exert a stress on the pivot module.

摘要： The present invention relates to a shock-absorber device for a wheel arbor of a micromechanical device comprising a support which includes a turning-arbor delimited by a rim defining a housing into which a pivot module is inserted, wherein this pivot module comprises a setting having a central orifice into which is inserted a bored stone, wherein an endstone (34) is placed on top of the bored stone, wherein the shock-absorber device also comprises a spring ring arranged between the support and the pivot module, wherein the shock-absorber device is equipped with a bayonet system for mounting the spring ring, wherein this bayonet system comprises a peripheral shoulder under which is formed a circular groove which defines a holding area, wherein the spring ring is equipped on an outer periphery with at least one catch, wherein at least one first notch which leads to the circular groove is provided in the peripheral shoulder, such that it is simply necessary to present the spring ring in such a way that the catch is engaged in the corresponding first notch, and then pivoting the spring ring so as to enable the catch to slide inside the circular groove, under the peripheral shoulder, wherein at least one second notch is machined in the peripheral shoulder, such that the catch is interlocked in this second notch, ensuring the angular pivot locking of the spring ring.

摘要： A display mechanism including a mechanism for fast correction of a position of a display wheel set, an intermediate wheel set ensuring synchronization with an automatic drive mechanism, and, inserted between the intermediate wheel set and the display wheel set, a safety lever driven by the display wheel set during periodic driving thereof, in a trajectory that interferes with a spatial volume of the intermediate wheel set, such that, when the intermediate wheel set is correctly synchronized, the trajectory of the lever does not interfere with the intermediate wheel set, and, when the intermediate wheel set is not correctly synchronized, the trajectory of the safety lever interferes with the intermediate wheel set, which the safety lever then drives in an opposite direction to a single direction of normal operation, to resynchronize the intermediate wheel set.

The pivot module includes a setting having a central orifice into which is inserted a bored stone. An endstone is placed on top of the bored stone. The shock-absorber device also includes a spring ring arranged between the support and the pivot module. The shock-absorber device is equipped with a bayonet system for mounting the spring ring. The bayonet system includes a peripheral shoulder under which is formed a circular groove which defines a holding area. The spring ring is equipped on an outer periphery with at least one catch. At least one first notch which leads to the circular groove is provided in the peripheral shoulder.

摘要： A lever for transmitting motion from an input wheel set pivoting about a first axis on a pivoting plate of the lever, to a receiver wheel set, the input wheel set permanently transmitting its motion to an output wheel set carried by the plate and pivoting under the action of the input wheel set about a second axis whose angular position is variable relative to the first axis, and the lever includes a first friction connection between a first friction surface of the input wheel set and a second friction surface of the plate, this first friction connection is weaker or stronger than a second friction connection between a third friction surface of the output wheel set and a fourth friction surface of the plate included in the lever.
