Vibrator for mechanical clock movement

摘要

The present invention relates to an oscillator for adjusting a mechanical timepiece movement, the oscillator (1) comprising an escapement wheel (5) and a resonator (3) that forms the time base of the oscillator (1); the resonator (3) including a mass element (32) that is kept in oscillation by at least two vibrating elements (31); the mass element (32) including at least one anchor portion (4) that is rigidly connected to the mass element (32), and is configured so as to directly engage with the escapement wheel (5) in order to maintain oscillations of the resonator (3), and so as to allow the escapement wheel (5) to move with each alternation of the oscillations; the first resonator (3) also including a base (2) that is intended to be mounted in a stationary or movable manner on the timepiece movement; the mass element (32) being supported only by the base (2) via the vibrating element (31).
