Problems solved by technology

It is clear that the anti-seismic systems proposed so far for resonators with flexible bearings only protect the belt from shocks in some directions, not all directions, or that they have the disadvantage of allowing the Its connection point moves slightly, which should be avoided as much as possible

Embodiment Construction

[0028] The present invention relates to a timepiece resonator mechanism forming a variant of the resonators disclosed in Swiss patent application CH 00518 / 18 in the name of ETA Manufacture Horlogère Suisse and in European patent application EP 18168765.8, which are hereby incorporated by reference, And those skilled in the art can combine its features with the features of the present invention.

[0029] The timepiece resonator mechanism 100 comprises a structure 1 and an anchoring unit 30 from which at least one inertial element 2 is suspended, the inertial element 2 being arranged in a first rotational degree of freedom about a pivot axis D extending in a first direction Z Oscillate on RZ. The inertial element 2 is subjected to a restoring force exerted by a flexible pivot 200 comprising a plurality of substantially longitudinal elastic bands 3 each secured at a first end to an anchoring unit 30 and at a second end to inertial element 2. Each elastic band 3 is deformable su...

Abstract

A timepiece resonator mechanism (100) includes a structure (1) carrying an anchor unit (30) via a flexible suspension system (300). An inertia element (2) oscillating around a pivot axis (D) extendingin a first direction (Z) with a first rotational freedom degree (RZ) under the action of return force exerted by a flexible pivot (200) including vertical elastic strips (3) is suspended from the anchor unit (30). The elastic strips (3) are fixed to an inertia element (2) and an anchor unit (30). The flexible suspension system (300) comprises an anchoring unit (300) and a transverse moving platform (32), which is directly or indirectly fixed to the structure (1) and is arranged between first middle mass blocks (303). The transverse moving platform comprises straight transverse strips or flexible shafts (320, 1320), which extend in a second direction (X) which is orthogonal with a first direction (Z) and are symmetrical to each other relative to a transverse axis (D2) that is intersected with the pivot axis (D).

Description

technical field [0001] The invention relates to a timepiece resonator mechanism comprising a structure and an anchoring unit on which at least one inertial element is suspended, the inertial element being arranged in a first rotation about a pivot axis extending in a first direction Z Oscillating in a degree of freedom RZ, said inertial element is subject to a restoring force applied by a flexible pivot comprising a plurality of substantially longitudinal elastic bands each fixed at a first end to said anchoring unit, and Fixed at a second end to said inertial element, each said elastic band is deformable substantially in a plane XY perpendicular to said first direction Z. [0002] The invention also relates to a timepiece oscillator comprising at least one such resonator mechanism. [0003] The invention also relates to a timepiece movement comprising at least one such oscillator and / or at least one such resonator mechanism. [0004] The invention also relates to a watch co...
