Horological linkage mechanism with flexible guidance

Abstract

A linkage mechanism (100) for a horological mechanism, for transmitting a movement between an actuator and a receiver, including a structure (10) relative to which a carrier (9), movable according to a single degree of freedom under the action of the actuator, is connected to the structure (10) by at least one flexible guide (50), each of the carrier (9) and the structure (10) being more rigid than each flexible guide (50), at least one flexible guide (50) is planar, and includes flexible necks (51), with a smaller section than the elements that are adjacent thereto, and/or flexible blades (5, 6, 52), with a smaller section than the elements that are adjacent thereto, and forming articulations. At least two arms are articulated to the structure (10) at two distinct points, and kinematically cooperate with each other, or with a tertiary bar or a tertiary structure.

Dependencies are inferred from the claim text.
