Abstract

Le chronographe comprend un affichage secondaire (16, 17) des fractions de seconde coopérant avec un mécanisme d'actionnement (20) comportant un limaçon (21) entraínée par un mécanisme chronographe (4). Un poussoir (19) agit sur des organes de mise en action (40, 46) pour libérer une bascule principale (30) qui relève la fraction de seconde chronométrée sur le limaçon (21) par un tenon (35) et entraíne une aiguille d'affichage (16) au moyen d'un train d'engrenage (33). Des premiers moyens de blocage (58) permettent d'isoler le marteau (54) du chronographe pour empêcher une mise à zéro pendant la lecture de la fraction de seconde. Des seconds moyens de blocage (59) inhibent un départ du chronographe pendant cette lecture et empêche une mise en action du mécanisme d'actionnement (20) pendant la marche du chronographe. Des troisièmes moyens (66) bloquent le limaçon (21) pendant la lecture des fractions de seconde.The chronograph includes a secondary display (16, 17) of the fractions second cooperating with an actuating mechanism (20) comprising a snail (21) driven by a chronograph mechanism (4). A pusher (19) acts on actuating members (40, 46) to release a main rocker (30) which records the fraction of a second timed on the snail (21) by a tenon (35) and drives a display needle (16) by means of a train gear (33). First blocking means (58) make it possible to isolate the hammer (54) of the chronograph to prevent zeroing during reading of the fraction of a second. Second blocking means (59) inhibit a start of the chronograph during this reading and prevents an activation of the actuation mechanism (20) while the chronograph is running. Of third means (66) block the snail (21) during the reading of the fractions second.

On obtient ainsi une lecture des fractions de seconde chronométrées à la demande de l'utilisateur d'une grande fiabilité et précision mécanique sans risque d'endommager des pièces du chronographe.

Figure 00000001
A reading of the timed fractions of a second is thus obtained at the request of the user, with high reliability and mechanical precision without the risk of damaging parts of the chronograph.
