Description
<B>Pièce d'horlogerie à remontage automatique.</B> La présente invention a pour objet. une pièce d'horlogerie à remontage automatique par masse mobile.
Cette pièce d'horlogerie est caractérisée en ce que la masse entraîne le rochet de barillet par l'intermédiaire d'un mobile coaxial au ba rillet et coopérant avec un renvoi conduisant le rochet de barillet.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de ].'objet de l'invention.
La fig. 1 est une vue en plan de la pièce d'horlogerie, et la fi-. 2 est une coupe suivant II-II de la fig. 1.
La masse mobile, désignée par 1, est pi votée au centre de la pièce d'horlogerie. Elle est solidaire d'un pignon 2 engrenant avec une roue 3, laquelle conduit une roue 4. La roue 3 entraîne, par l'intermédiaire d'un accouplement Breguet 5, une roue 6, tandis que la roue 4 entraîne, par l'intermédiaire d'un accouplement Breguet 7 identique au précédent, une roue 8. Les roues 6 et 8 en grènent toutes deux avec une roue 9 d'un mobile coaxial au barillet. et monté fou sur l'arbre 10 de ce dernier.
Le pignon 11 .de ce mobile conduit une roue 12 d'un renvoi, ,dont le pignon 13 conduit le rochet de barillet, dé signé par 14 et monté sur un carré de l'arbre 1.0.
Les roues 3, 4, 6 et 8 et les accouple- ments Breguet 5 et 7 constituent un dispo- sitif grâce auquel le mobile 9-11 est en traîné dans un seul. sens, quel que soit le sens de rotation de da masse. On pourra prévoir d'autres dispositifs d'entraînement à sens unique. Celui-ci a cependant l'avantage de supprimer la nécessité d'un cliqu et de retenue pour le train de remontage.
En effet, en cas de retour en arrière, les roues 3-6, 4-8 et 9 fonctionnent comme trois roues engrenant les unes avec les autres et bloquent le train de remontage.
L'emploi du renvoi 12-13 permet d'obte nir la démultiplication voulue entre le mo bile 9-11 et le rochet 14 de barillet.
On remarquera que le -dispositif d'en traînement à sens unique est situé avant le dispositif démultiplicateur, de sorte que de faibles déplacements de la masse suffisent au passage d'une dent à l'autre des accouple- ments Breguet.
<B> Self-winding timepiece. </B> The present invention relates to. a timepiece with automatic winding by moving mass.
This timepiece is characterized in that the mass drives the barrel ratchet by means of a mobile coaxial with the bolt and cooperating with a reference driving the barrel ratchet.
The accompanying drawing shows, by way of example, one embodiment of the object of the invention.
Fig. 1 is a plan view of the timepiece, and the fi. 2 is a section along II-II of FIG. 1.
The moving mass, designated by 1, is pi voted in the center of the timepiece. It is integral with a pinion 2 meshing with a wheel 3, which drives a wheel 4. The wheel 3 drives, via a Breguet coupling 5, a wheel 6, while the wheel 4 drives, via the intermediary of a Breguet coupling 7 identical to the preceding one, a wheel 8. The wheels 6 and 8 both mesh with a wheel 9 of a mobile coaxial with the barrel. and mounted crazy on the shaft 10 of the latter.
The pinion 11 .de this mobile drives a wheel 12 of a return, whose pinion 13 drives the barrel ratchet, die signed by 14 and mounted on a square of the shaft 1.0.
The wheels 3, 4, 6 and 8 and the Breguet couplings 5 and 7 constitute a device thanks to which the mobile 9-11 is dragged in a single one. direction, whatever the direction of rotation of da mass. Other one-way drive devices can be provided. However, this has the advantage of eliminating the need for a click and restraint for the winding train.
Indeed, in the event of reverse, the wheels 3-6, 4-8 and 9 function as three wheels meshing with each other and block the winding train.
The use of the reference 12-13 makes it possible to obtain the desired reduction between the mo bile 9-11 and the ratchet 14 of the barrel.
It will be noted that the one-way driving device is located before the reduction device, so that small movements of the mass are sufficient for the passage from one tooth to the other of the Breguet couplings.
