Abstract (en)

[origin: JP2019191160A] To provide a strip resonator with an RCC flexure pivot.SOLUTION: The present invention relates to a timepiece resonator mechanism 100 including a structure 1 and an inertia element 2 oscillating about an axis D. The inertia element 2 is subjected to return forces exerted by an RCC flexure pivot 200 with elastic resonator strips 3. The elastic resonator strips 3 are each fixed to the structure 1 and to the inertia element 2 and essentially deformable in a plane perpendicular to the axis D, straight and extending in parallel or coincident planes. Crossing, in projection onto a plane perpendicular to the axis D, in directions of the strips 3 defines the axis D. The strips 3 are fixed on the inertia element 2 side to a stiff element 13 comprised in an anti-shock element 10, and on which stiff element 13 are fixed the strips 3. The stiff element 13 is integral with anti-shock flexible elements 11 arranged to keep the inertia element 2 suspended, the anti-shock element 10 providing shock protection for the strips 3 of the flexure pivot 200.SELECTED DRAWING: Figure 1
