Abstract (en)
[origin: US2024061377A1] A regulating member for a horological movement includes an oscillating weight, for example a balance, a balance spring including a flexible strip wound about itself in a plurality of turns, the strip having a predefined rigidity to allow the oscillating weight to undergo a rotary oscillatory motion, and the strip including an outer end of the strip. The regulating member includes a resilient device for compensating for external pressure, connecting the outer end to a first support that is immobile with respect to the horological movement, the resilient compensation device being configured to adapt its stiffness according to the external pressure in order to compensate for an effect of the external pressure on the regulating member. Additionally, the horological movement includes the regulating member.
Abstract (fr)
L'invention concerne un organe réglant (1) pour mouvement d'horlogerie comprenant une masse oscillante (19), par exemple un balancier, un ressort-spiral comprenant un ruban (2) flexible enroulé sur lui-même selon plusieurs spires, le ruban (2) ayant une rigidité prédéfinie pour permettre à la masse oscillante d'effectuer un mouvement oscillatoire rotatif, le ruban (2) comprenant une extrémité externe (9)du ruban '2), l'organe réglant (1) comprenant un dispositif élastique de compensation (50) de la pression extérieure, reliant l'extrémité externe (9) à un premier support immobile (7) par rapport au mouvement d'horlogerie, le dispositif élastique de compensation (50) étant configuré pour adapter sa raideur en fonction de la pression extérieure afin de compenser l'effet de la pression extérieure sur l'organe réglant (1).L'invention concerne aussi un mouvement d'horlogerie comprenant un tel organe réglant (1).
