Embodiment Construction

[0046] Figure 1 to Figure 3 A first embodiment of a flexible guide 1 for a rotating resonator mechanism, in particular for a timepiece movement, is shown. The flexible guide 1 is arranged substantially in one plane. The flexible guide comprises: a fixed support 2; a movable element 20 movable relative to the fixed support 2; and three main flexible blades 3, 4, 5 each connecting the movable element 20 to the support 2. The main flexible blades 3 , 4 , 5 allow the movable element 20 to move relative to the fixed support 2 . By bending the main flexible blades 3, 4, 5, the movable element 20 can be moved relative to the support 2 in a rotational movement about itself around the center of rotation. The main blades 3, 4, 5 preferably have the same length and are evenly angularly distributed around the central portion 6 of the movable element 20 so as to form a symmetrical pivot.

[0047] According to the invention, the flexible guide 1 comprises a translation stage 10 , 11 , ...

Abstract

The invention relates to a flexible guide (1) for a rotary resonator mechanism, in particular for a timepiece movement, the guide (1) comprising: a fixed support (2); a movable element (20) movable relative to the fixed support (2); at least one main flexible blade (3, 4, 5) allowing the movable element (20) to move relative to the fixed support (2) via a rotational movement about a center of rotation by bending one or more main flexible blades (3, 4, 5), the flexible guide (1) being substantially arranged in a plane and comprising at least one translation stage (10, 11, 12) linked to one end of the main flexible blade (3, 4, 5), the main flexible blade (3, 4, 5) and the translation stage (10, 11, 12) form a pair connected to the fixed support, the movable element (20) or the intermediate movable part, such that the translation stage (10, 11, 12) is configured to move in translation at least partially under the influence of the bending of the main flexible blade (3, 4, 5).

Description

technical field [0001] The invention relates to a flexible guide with a translation stage for a rotating resonator mechanism, in particular for a timepiece movement. The invention further relates to a rotating resonator mechanism provided with such a flexible guide. Background technique [0002] Most of today's mechanical watches are equipped with a balance spring and a Swiss pallet escapement. The balance spring forms the time base of the watch. It is also called a resonator. [0003] The escapement has two main functions: [0004] - maintain the back and forth motion of the resonator; [0005] - Count these back and forth movements. [0006] Inertial elements, guides and elastic return elements are required in order to form a mechanical resonator. Conventionally, a spiral balance spring acts as the elastic return element of the inertial element constituted by the balance wheel. This balance wheel is guided in rotation by a pivot rotating inside a plain ruby ​​bearin...
