Description

lllecanisme de remontoir pour montres. Lobjet de la presente invention est un mecanisine de reinontoir pour montres, com- prenant une masse oscillante. <B>Co</B> mecanisme est caract6ris6 par un organe rotatif, i,eli6 ä celles des extremitds de ressort-moteur par oü se produit 1e remontage, et sur lequel est fix6 un rocket et par deux roues montees (olles sur cet organe, de part et d'autre du rocket et engrenant, 1'un directement, et l'autre, parl'interm6diaire d'un renvoi, avec un pignon m6, par la masse motrice, chacune de ces roues folles portant un cliquet coop6rant avec le rocket sus-mentionne. Winding mechanism for watches. The object of the present invention is a reinuntoir mechanism for watches, comprising an oscillating weight. <B>Co</B> mechanism is characterized by a rotating member, linked to those of the ends of the mainspring through which the winding takes place, and on which is fixed a rocket and by two wheels mounted (on this organ, on either side of the rocket and meshing, one directly, and the other, via a transmission, with a driven pinion, by the driving mass, each of these idler wheels carrying a cooperating pawl with the aforementioned rocket.

La figure unique du dessin est une coupe dune forme d'ex6cution, donnee ä titre d'exemple, de 1'objet de la pr6sente invention. The single figure of the drawing is a section of an embodiment, given by way of example, of the subject of the present invention.

1 est la masse de remontage pouvant osciller autour de Faxe gdom6trique de laxe _n6can:,.ue 2, sur un carr6 duquel elle est fix6e; sur cet axe 2 est cal6 un pignon 3 qui commande une roue 4 pouvant tourner librement sur laxe 5 et entrainant ce der- nier, par 1'interm6diaire dune rondelle 61asti- quo concave-convexe 6 qui est ajustde sur um carre de laxe 5 et qui appuie @astique- ment sur la roue 4; 7 est un pignon fix6 ä faxe 5 et qui entraine 1e pignon 8, par 1'in- term6diaire de la roue 9. 1 is the winding mass which can oscillate around the geometrical axis of the axis _necan:,.ue 2, on a square of which it is fixed; on this axle 2 is fixed a pinion 3 which controls a wheel 4 which can rotate freely on the axle 5 and driving the latter, through the intermediary of a concave-convex washer 61 which is adjusted on a square of the axle 5 and which presses aggressively on wheel 4; 7 is a pinion fixed to axle 5 and which drives pinion 8, via wheel 9.

10 est 1e barillet sur 1'arbre 11 duquel est fixe, par un carr6, un rocket 12 situ6 entre los deux roues 13 et 14, montees (olles sur 1'arbre 11 et portant chacune un oliquet 15, dont 1e point d'articulation du ressort est montre en 16; los deux cliquets 15 tra- vaillent avec 1e rocket 12; 17 est 1e rocket de remontage habituel, cooperant avec 1e cliquet de retenue 18. La roue 14 engrene direotemeilt avec 1e pignon 8, tandis quo la roue 13 engrene avec 'Co meme pignon, par 1'interm6diaire du renvoi 19. 10 is the first barrel on the shaft 11 of which is fixed, by a square, a rocket 12 located between the two wheels 13 and 14, mounted (olles on the shaft 11 and each carrying a latch 15, the first point of articulation of the spring is shown at 16, the two pawls 15 working with the rocket 12, 17 is the usual winding rocket, cooperating with the retaining pawl 18. The wheel 14 meshes directly with the pinion 8, while the wheel 13 meshes with the same pinion, via transmission 19.

Supposons quo la masse de remontage oscille dann un sens tel quo 1e pignon 8 tourne dans 1e sens de la flecke fl; la roue 13 tournera dann 1e meme sens, et par son cliquet 15 entrainera 1e rocket 12; la roue 14, par contre, tournera en sens inverse et son cliquet glissera sur les dents du rochet 12. Si la masse de remontage oscille en sens contraire, ce sera la roue 14 qui entraî nera le rochet 12, tandis que le cliquet de la roue 13 glissera sur les dents de ce rochet. Suppose that the winding mass oscillates in one direction such that the pinion 8 rotates in the direction of the fleck fl; the wheel 13 will turn in the same direction, and by its pawl 15 will drive the rocket 12; wheel 14, on the other hand, will turn in the opposite direction and its pawl will slide on the teeth of ratchet 12. If the winding mass oscillates in the opposite direction, it will be wheel 14 which will drive ratchet 12, while the pawl of the wheel 13 will slide on the teeth of this ratchet.

Claims

CLAIM Winding mechanism for watches, comprising an oscillating weight, characterized by a rotating member, connected to those of the ends of the mainspring through which the winding takes place, and on which is fixed a ratchet and by two loose wheels mounted on this member, on either side of the ratchet and meshing, one directly, and the other, via a transmission, with a pinion moved by the drive mass, each of these idler wheels carrying a cooperating pawl with the aforementioned ratchet.
