Embodiment Construction

[0050] Figure 1 to Figure 9 A flexible guide is shown for a rotating resonator mechanism, in particular for a timepiece movement. The flexible guides 1 , 10, 20, 30, 40, 50, 60, 70, 80 are arranged substantially in one plane. The flexible guide comprises a fixed support 2 , a movable element 3 movable relative to the fixed support 2 and a main flexible blade 4 connecting the movable element 3 to the support 2 . The main flexible blade 4 allows the movable element 3 to move relative to the fixed support 2 . By bending the main flexible blade 4, the movable element 3 can move relative to the support 2 in a rotational movement around the center of rotation. The movable element 3 comprises a cylindrical part.

[0051]According to the invention, the flexible guide 1 , 10 , 20 , 30 , 40 , 50 , 60 , 70 , 80 comprises a translation stage 5 , 15 , 25 joined to one end of the main flexible blade 4 . In this embodiment, translation stages 5 , 15 , 25 are arranged in series between t...

Abstract

The invention relates to a flexible guide (1) for a rotary resonator mechanism, in particular for a timepiece movement, comprising a fixed support (2), a movable element (3) movable relative to the fixed support (2), at least one main flexible blade (4), the movable element (3) is allowed to move relative to the fixed support (2) with a rotational movement about a center of rotation by bending the main flexible blade (4), the flexible guide (1) being substantially arranged in a plane and comprising at least a first translation stage (5) linked to one end of the main flexible blade (4), the flexible guide (1) is arranged such that the first translation stage (5) is configured to translate at least partially under the influence of the bending of the main flexible blade (4), the flexible guide (1) comprising adjusting means for adjusting the stiffness of the first translation stage (5).

Description

technical field [0001] The invention relates to a flexible guide with adjustable translation stages for rotating resonator mechanisms, in particular for timepiece movements. The invention also 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 in turn fulfills two main functions: [0004] - maintain the reciprocating movement of the resonator; [0005] - Count these reciprocations. [0006] In order to construct a mechanical resonator, inertial elements, guides and elastic return elements are required. Usually, the spiral balance spring acts as the elastic return element for the inertial element constituting the balance wheel. This balance wheel is guided by a pivot rotating in smooth ruby ​​bearings. Thi...
