Abstract
A tuning-fork mechanical resonator for a mechanical clock movement with free escapement includes an oscillator of the tuning fork type, of which at least one first prong is intended to oscillate about a first axis and bears at least one first pin associated with at least one first fork tooth of a pallet assembly to cause this assembly to pivot between first and second angular positions and alternately lock and release an escapement wheel. The resonator comprises a conversion member secured to the first pin and designed to on the one hand, convert the oscillations of the first prong of the oscillator into rotational movements of the pallet assembly by transmitting first impulses thereto, and on the other hand, transmit mechanical energy from the pallet assembly to the first prong of the oscillator in the form of impulses.
