Embodiment Construction

[0050] Refer below Figure 1 to Figure 8 A first embodiment of the timepiece 600 will be described. For example, the timepiece is a watch, especially a watch. The timepiece comprises a first embodiment of a watch movement 500 , which is in particular a mechanical movement. This movement comprises a first variant of the first embodiment of an escapement 400 located between the gearing and the oscillator 4 , 5 .

[0051] The gearing is designed to connect the starting device (eg barrel) to the escapement. Thus, the gearing enables the transfer of energy from the engine to the escapement. For the escapement, it can provide energy to the oscillator to maintain its oscillation.

[0052] For example, the oscillator is of the balance 4 and spring 5 type. The balance wheel pivots about axis A4.

[0053] The escapement 400 basically comprises a first escape wheel 1 pivoting about an axis A1 , a second escape wheel 2 pivoting about an axis A2 and a blocking lever 3 pivoting about ...

Abstract

The present invention relates to an escapement device (400), comprising a first escapement wheel (1), a second escapement wheel (2) and a brake lever (3), the second escapement wheel being arranged on the Between the first escape wheel and the brake lever, in particular the second escape wheel comes into contact and engages with the first escape wheel and the brake lever.

Description

technical field [0001] The invention relates to a method of operating a timepiece escapement. The invention also relates to a timepiece escapement. The invention also relates to a watch movement comprising such a device. The invention finally relates to a timepiece comprising such a device or such a watch movement. The invention also relates to a transmission and a timepiece comprising such a transmission. Background technique [0002] Known escapements such as the Swiss lever escapement or the Robin escapement, such as the escapement described in patent EP1122617B1, generally comprise an escape wheel and a blocking lever. The escape wheel is formed by a first escape pinion engaged with or participating in the gear train of the timepiece movement, and an escape wheel designed to cooperate by contact with a blocking lever, itself designed to oscillate The device, especially the balance with hairspring, especially the impact pin of the balance with hairspring, is engaged b...
