Abstract (en)
[origin: JP2017134070A] PROBLEM TO BE SOLVED: To improve the timepiece resonator mechanism with a two-dimensional crossed-strip pivot.SOLUTION: A resonator mechanism 1 comprises a flexure pivot mechanism 10, and a first fixed support 11 and a second fixed support 12 to which is attached, respectively by a first resilient assembly 21 and a second resilient assembly 22 which together define a virtual axis A, a rotary support 3 holding a pivoting weight 2. The flexure pivot mechanism 10 is planar. The first resilient assembly 21 includes, on either side of the virtual axis A, a first outer flexible strip 31 and a first inner flexible strip 41, joined to each other by a first intermediate strip 51 stiffer than each of the strips, which strips together define a first direction D1 passing through the virtual pivot axis A. The second resilient assembly 22 includes a second flexible strip defining a second direction D2 passing through the virtual pivot axis A.SELECTED DRAWING: Figure 6
