Abstract
Device for timepiece comprising a monolithic mechanism which comprises a support and an inertial regulating member connected to the support by an elastic suspension. The elastic suspension comprises an elastic adjustment link having a first end adjustable relative to the support, so as to change the overall stiffness of the elastic suspension and therefore the oscillation frequency of the inertial regulating member.
Claims17
A device for timepieces comprising a monolithic mechanism which comprises:
- a support;
- at least one inertial regulating member;
- an elastic suspension linking said at least one inertial regulating member to the support and having a specific overall stiffness;
- where said at least one inertial regulating member is suited to oscillate at a frequency f relative to the support;
- wherein the elastic suspension comprises an elastic adjustment link having a first end linked to said at least one inertial regulating member and a second end which is directly connected to the support by a frequency adjustment device suited to modify the position of the second end of said elastic adjustment link relative to the support, so as to change the overall stiffness of the elastic suspension and therefore said frequency f.
