Title:
剛性を調整するための手段を備えた可撓性ガイドを有する計時器用発振器機構
Document Type and Number:
Japanese Patent JP7238085
Kind Code:
B2
Abstract:
A rotating resonator mechanism (60) including a flexible guide (5) and an oscillating mass (2), the flexible guide (5) including two main flexible strips (4, 6) and a rigid portion (7). The flexible strips are joined to the rigid portion and the oscillating mass. An adjustment means adjusts the stiffness of the resonator mechanism, and includes a flexible element connected to the rigid portion and to a fixed support (11), so that the flexible guide (5) is suspended by the flexible element (12), the flexible guide (5) and the flexible element (12) extending substantially in the same plane so that the oscillating mass (2) performs a rotating movement about a virtual pivot. The adjustment means also includes pre-stressing means (15) to apply a variable force or torque on the flexible element (12) or the flexible guide (5), to vary the stiffness of the flexible element (12).
