Description
Dispositif d'actionnement d'un mécanisme de chronographe. L'objet de la. présente invention est un dispositif d'actionnement -d'un mécanisme de chronographe comportant deux poussoirs sou mis à l'action d'un dispositif élastique anta- boniste indépendant du mouvement,
caracté risé en ce que -ce -dispositif élastique est cons titué par une lame-ressort logée sans tension dans une creusure intérieure du corps de boîte et dont chaque extrémité s'appuie librement sur la face intérieure de l'un -des poussoirs.
Le dessin ci-annexé représente, à titre d'exemple, une forme d'exécution -du dispo sitif faisant l'objet de l'invention.
La fi-. 1 est une coupe horizontale du chronographe muni de -cette forme d'exé cution, la fig. 2' est une coupe partielle à plus grande échelle du -dispositif et la fig. 3. est une coupe suivant la ligne III-III de la fig. \c.
Le chronographe représenté en fig. 1 comprend un mouvement rond .logé dans une boîte ronde dont la carrure 1 est seule repré- sentée. Son mécanisme est actionné par deux poussoirs 2 disposés de part et d'autre du tube 3. .de guidage de da tige de remontoir.
La carrure 1 présente une creusure périphé rique intérieure l' dans laquelle est logée, sous tension, une lame-ressort 4, droite à l'état détendu, dont chaque extrémité s'appuie librement sur la face intérieure de l'un des poussoirs 2.
Un déplacement tangentiel -du ressort 4 est exclu du fait que ses deux extré mités butent contre les canons 5 que pré sentent les poussoirs 2! sur leur face inté rieure; ces canons sont guidés dans des trous ménagés dans des brides 6 unissant les deux parois de la creusure l' de lu, carrure et des vis 7 vissées dans les canons 5 retiennent les poussoirs en place. La dame-ressort 4 se main tient en place dans la rainure l' par sa propre élasticité sans l'intervention d'aucun moyen de fixation ou de guidage.
Device for actuating a chronograph mechanism. The object of the. present invention is a device for actuating a chronograph mechanism comprising two push-pieces subjected to the action of an elastic anti-bonist device independent of the movement,
character ized in that -this -dispositif elastic is constituted by a leaf spring housed without tension in an interior recess of the box body and each end of which rests freely on the interior face of one -the pushers.
The appended drawing represents, by way of example, an embodiment of the device forming the subject of the invention.
The fi-. 1 is a horizontal section of the chronograph provided with this embodiment, FIG. 2 'is a partial section on a larger scale of the -dispositif and FIG. 3. is a section taken along line III-III of FIG. \vs.
The chronograph shown in fig. 1 comprises a round movement housed in a round case of which the caseband 1 is the only one shown. Its mechanism is actuated by two pushers 2 arranged on either side of the guide tube 3. of the winding stem.
The caseband 1 has an inner peripheral hollow 1 'in which is housed, under tension, a leaf spring 4, straight in the relaxed state, each end of which rests freely on the inner face of one of the pushers 2. .
Tangential displacement of the spring 4 is excluded because its two ends abut against the barrels 5 which the pushers 2 present! on their inner face; these barrels are guided in holes made in flanges 6 uniting the two walls of the recess l 'of the middle part and screws 7 screwed into the barrels 5 hold the pushers in place. The lady-spring 4 is held in place in the groove 1 'by its own elasticity without the intervention of any fixing or guiding means.
