Abstract

Le mécanisme d'isolation de rattrapante comprend un levier de rattrapante (12), pivoté sur une roue de rattrapante (11) coaxiale à une roue de chronographe (4), apte à être en contact sous l'action d'un ressort de levier (13) avec un coeur (6) solidaire de la roue de chronographe (4). Il comporte un dispositif de diaphragme présentant plusieurs bielles (26) reliant une bague de commande (20) concentrique à la roue de rattrapante (11) à plusieurs pièces mobiles (27, 28,29) comportant chacune une partie médiane en forme d'arc de cercle de telle manière qu'un déplacement angulaire de la bague de commande provoque un rapprochement ou un éloignement des parties médianes (28) des pièces mobiles (27, 28, 29) de l'axe (5) de la roue de chronographe.

Figure imgaf001
The split-second isolation mechanism comprises a split-lever (12), pivoted on a split-second wheel (11) coaxial with a chronograph wheel (4), able to be in contact under the action of a lever spring (13) with a heart (6) integral with the chronograph wheel (4). It comprises a diaphragm device having a plurality of connecting rods (26) connecting a control ring (20) concentric with the split-second wheel (11) with a plurality of moving parts (27, 28, 29), each having a bow-shaped middle portion. in such a way that an angular displacement of the control ring causes the middle parts (28) of the moving parts (27, 28, 29) to move towards or away from the axis (5) of the chronograph wheel.
