Title:
FLEXIBLE GUIDE AND SET OF SUPERIMPOSED FLEXIBLE GUIDES FOR ROTARY RESONATOR MECHANISM, IN PARTICULAR OF HOROLOGICAL MOVEMENT
Document Type and Number:
Japanese Patent JP2021067675
Kind Code:
A
Abstract:
To provide a flexible guide and a set of superimposed flexible guides for a rotary resonator mechanism, in particular of a horological movement.SOLUTION: A flexible guide includes a first support 11, an element 13 movable relative to the first support, and a first pair of flexible strips 14, 15 connecting the first support to the movable element, so that the movable element can be displaced relative to the first support by bending the strips 14, 15 in a circular movement about a center 18 of rotation. The flexible guide is arranged substantially in a specific plane. In the flexible guide, prestressing means 27 is configured to apply a force for buckling the flexible strips by bringing the first support closer to the movable element, so that the flexible guide includes two stable positions 28 of the element 13 movable relative to the first support 11 for which the return moment is zero, the two stable positions having a predetermined angle of rotation (2α) therebetween.SELECTED DRAWING: Figure 2
