| 摘要 |
<p>The invention relates to an escapement mechanism adapted for transmitting mechanical energy pulses from a driving source to an oscillating regulator of a timepiece via a blade spring (12) operating in a buckling manner about a curvature point, wherein said blade spring (12) can build up the energy from the driving source between two pulses and transmit the same to the oscillating regulator upon each pulse via first (18) and second (26) levers. In order to optimise the adjustment of the tension of the blade spring (12), the latter is mounted on a frame (50) capable of symmetric deformation relative to a first axis (AA) extending through the rotation axes of the regulator, the levers (18, 26) and through the curvature point, and relative to a second axis (BB) perpendicular to the first one and extending through the ends of the blade spring (12).</p> |
