Description

Mecanisme de remontage et de mise ä 1'heure ä tirette pour piece d'horlogerie Lobjet de la prdsente invention est un mecanisme de remontage et de mise ä 1'heure ä tirette pour pike d'horlogerie, dans lequel Faxe de la tirette peut se deplacer axialement pour engager la tirette avec la tige de remon- toir ou 1'en degager. Ce mecanisme est carac- t6ris6 par 1e fait que Forgane commandant ce deplacement axial de laxe *de tirette est cons- titu6 par une tige, montee rotativement dans 1e mouvement, dont 1'extremite intdrieure est munie dune came pdnetrant dans un 6vide- ment correspondant de laxe, alors que son ex- tr6mit6 exterieure fait saillie sur 1e mouve- ment. Mechanism for winding and setting the time with pull tab for a timepiece The object of the present invention is a mechanism for winding and setting the time with pull tab for a timepiece, in which move axially to engage the pull tab with the winding stem or disengage it. This mechanism is characterized by the fact that the organ controlling this axial displacement of the axis of the pull rod is constituted by a rod, mounted rotatably in the movement, the inner end of which is fitted with a cam penetrating into a corresponding recess. of the axis, while its outer extremity protrudes over the movement.

Le dessin ci-annexe represente, ä eitre d'exemple, une forme d'execution de Fobjet de la presente invention. The attached drawing represents, by way of example, one embodiment of the object of the present invention.

La fig. 1 en est une vue en dlevation, mon- trant la platine vue du cötd cadran. fig. 1 is an elevational view, showing the plate seen from the dial side.

La fig. 2 en est une vue partielle, en plan, ä plus Brande khelle. fig. 2 is a partial view, in plan, ä plus Brande khelle.

Les fig. 3 et 4 sont des coupes ä plus Brande echelle, par 111-III de la fig. 1, respecti- vement IV-IV de la fig. 3. Au dessin, 1 reprdsente la platine, 2 la tige de remontoir et 3 la tirette logge dans un evidement 4 de la platine. - 5 est 1e tenon de cette tirette penetrant dans la Borge de la tige de remontoir. 6 est son axe qui peut coulisser axialement dans 1e mouvement, et 7 est 1e talon sur lequel agit 1e ressort de tirette non representd. Figs. 3 and 4 are sections on a larger scale, by 111-III of fig. 1, respectively IV-IV of FIG. 3. In the drawing, 1 represents the plate, 2 the winding stem and 3 the pull tab housed in a recess 4 of the plate. - 5 is the tenon of this slider penetrating into the Borge of the winding stem. 6 is its axis which can slide axially in the first movement, and 7 is the first heel on which the first pull-cord spring (not shown) acts.

L'organe de commande du ddplacement axial de Faxe de tirette 6 est une tige 8 mon- t6e rotativement dans 1e mouvement, pr6sen- tant ä son extrdmite interieure un excentrique 9 qui est engage Jans une ouverture corres- pondante 10 de Faxe et, ä son extremitd ex t6rieure, une petite manette 11 terminee par une ouverture 12 dans laquelle an peut enga- ger Fongle. The control member for the axial movement of the pull rod 6 is a rod 8 mounted rotatably in the movement, presenting at its inner end an eccentric 9 which is engaged in a corresponding opening 10 of the pull rod and, at its inner end, its outer extremity, a small lever 11 terminated by an opening 12 in which an can engage the fingernail.

Lorsqu'on tourne la tige 8 dans un sens, an deplace laxe de tirette, par exemple de droite ä Bauche en fig. 3, et Fon engage 1e tenon de celle-ci dans la Borge de la tige de remontoir. Inversement, lorsque 1'on tourne la tige dans Fautre sens, ön deplace Faxe de Bau- che ä drohe, en fig. 3, et 1e tenon de la tirette est ddgagd de la tige ; celle-ei peut alors eire sdparee du mouvement par simple action sur la manette 11. Une cheville 13, cooperant avec 1e fond plat 14 dune rainure 15, pratiqude dans la tige 8, limite les ddplacements de celle-ci dans les deux sens. When turning the rod 8 in one direction, an moves the axis of the zipper, for example from right to Bauche in fig. 3, and Fon engages the tenon of the latter in the Borge of the winding stem. Conversely, when the rod is turned in the other direction, ön moves Faxe from Bauche to right, in fig. 3, and the 1e tenon of the zipper is disengaged from the rod; it can then be separated from the movement by a simple action on the handle 11. A pin 13, cooperating with the first flat bottom 14 of a groove 15, practiced in the rod 8, limits the displacements of the latter in both directions.
