Problems solved by technology

[0010] In addition, the circular trajectory of the hinge points of the links and the variation of the orbital radius of the central control element caused by the variation of the driving torque are the reasons for the deterioration of the isochronism of the above-mentioned type of oscillators

Embodiment Construction

[0025] The invention will now be described in detail with reference to the accompanying drawings, which show by way of example various embodiments of the invention.

[0026] The invention relates to a timepiece setting device comprising an isotropic harmonic oscillator, which device is intended to be integrated into a timepiece.

[0027] Figure 1a A first embodiment of such a device is shown schematically and by way of example. This regulating device 1 comprises a rigid frame (not shown), two weights 2.1 , 2.2 formed by a timepiece balance mounted on said rigid frame to rotate about axes of rotation 2.1a, 2.2a. The adjusting device 1 also comprises drive means 3 adapted to be driven in rotation about the axis 3a of the oscillator by the movement of said timepiece. The drive means 3 comprises a slot 3b extending in a substantially radial direction with respect to the axis 3a of the oscillator and in which is accommodated a connecting element 4 adapted to move along the slot a...

Abstract

The invention relates to a setting device (1) comprising a harmonic oscillator and intended to be integrated into a watch. The setting device (1) is equipped with at least two weights (2.1, 2.2, 2.3,2.4) mounted so as to pivot, a drive means (3) rotated by a gear train of the watch, a linking element (4) kinematically connected to the drive means (3) in a substantially orthoradial direction and coupled with the oscillating weights, and a resilient recoil element arranged to provide the common recoil force to the pivoting weights, and tending to shift the connecting element (4) towards the axis of the oscillator (3a).

Description

technical field [0001] The subject of the invention is a regulating device based on a harmonic oscillator with a plurality of rotating weights and a common return force, which is intended to be integrated into a timepiece, in particular into a wristwatch. Embodiments of the invention specifically include oscillators with two or more degrees of freedom, wherein the elements follow a substantially circular or elliptical periodic trajectory when a central return force acts on them. These oscillators are also known as "isotropic harmonic oscillators". Background technique [0002] Since the advent of mechanical timepiece movements with escapements, several attempts have been made to produce regulating members that do not need to be coupled to the escapement. A recent example of such an effort is document WO2015 / 104692, which also includes a structured review of various theoretical approaches for fabricating such harmonic oscillators, as well as the theoretical basis of physics ...
