Description

Dispositif de remontage automatique de monvement d'horlogerie. Lobjet de la. presente invention est im dispositif automatique de remontage de mou-, vement d'horlogerie, du genre de ceux com- prena.nt une masse mobile reliee par un en- renage au ressort-moteur. Ce dispositif est g caracterise en ce que la masse porte, dune Part, un satsllite pouvant osciller librement sur lui-meme et engrenant avec 1e premier mobile de 1'engrenage, mobile autour duquel oscille la masse et, d'autre Part, un ressort de limitation dont une extremite est fixe par rapport ä. la masse et sur 1'autre egtre- mite duquel un organe du satellite vieret bu- ter lorsqu'il tourne dans 1e sens du remon- tage, ce qui permet ä celui-ei, dans ce sens, d'agir sur 1e ressort-moteur taut que celui-ci n'est pas remonte ä. fand, 1e satellite agissant, ä partir de ce moment, uniquement sur 1e ressort de limitation. Automatic watch winding device. The object of the. The present invention is an automatic device for winding movement, watch movement, of the kind comprising a moving mass connected by a gear to the mainspring. This device is g characterized in that the mass carries, on the one hand, a satellite which can oscillate freely on itself and meshing with the first mobile of the gear, mobile around which the mass oscillates and, on the other hand, a spring limitation, one end of which is fixed with respect to ä. the mass and on the other end of which a member of the satellite hits when it turns in the winding direction, which allows it, in this direction, to act on the spring. engine as long as it is not dated back to. fand, the satellite acting, from this moment on, solely on the limiting spring.

Le dessin ei-annexe represente, ä titre d'exemple, une forme d'execution de 1'ob jet de la presente invention. The appended drawing represents, by way of example, one form of execution of the object of the present invention.

La fix. 1 en est une vue en plan, et 1a fix. 2, une-coupe par 11-II de fix. 1. La masse de remontage comprend une teste 1 et un bras 2 solidaire de celle-ei et monte rotativement en 3 sur 1e bäti; autour de faxe 3 peut egalement tourner la roue 4 qui est 1e premier mobile d'un engrenage aboutissant au barillet moteur non represente. Le bras 2 porte un satellite 5 qui, dente sur 1e Hers ä peu pres de sa peripherie, peut osciller li- brement autour de son axe 6 et qui engrene avec 1a roue 4; 1e bras presente egalement une ereusure 7, 7a dans laquelle est loge un ressort-lame 8 de limitation en forme d'arc .de cercle et dopt les deux extremiths 8a et 8b viennent reposer contre des plats 9 et 10 de la paroi de la creusure; 1'extremite 8a reste immobile par rapport au bras 2, alors que 1'extremite 8b peut etre deplacee par une cheville 11 portee par une oreille 12 du sa- tellite 5; cette oreille est egalement soumise ä 1'action du ressort 13 plus faible que 1e ressort B. The fix. 1 is a plan view, and 1a fix. 2, one-cut through 11-II of fix. 1. The winding mass comprises a head 1 and an arm 2 secured thereto and rotatably mounted at 3 on the first frame; around fax 3 can also turn the wheel 4 which is the first moving part of a gear leading to the engine barrel not shown. The arm 2 carries a satellite 5 which, toothed on the hers approximately at its periphery, can oscillate freely around its axis 6 and which meshes with the wheel 4; the first arm also has a groove 7, 7a in which is housed a limiting leaf spring 8 in the shape of an arc. ; the end 8a remains stationary with respect to the arm 2, while the end 8b can be moved by a pin 11 carried by a lug 12 of the satellite 5; this ear is also subjected to the action of the spring 13 which is weaker than the spring B.

Lorsque la masse se deplacera dans 1e sens de la fleche f2, la dent 5a du satellite 5 sautera sirr les differentes. dents de 1a roue 4 ä 1'instar d'un cliquet, gräce ä 1'action du petit ressort 13, formant butee elastique. lite 5 will abut, by its pin 11, against the extremity 8b of the spring 8; this extremity will not give way and the satellite 5, being thus prevented from rotating on its own, will pivot, with the mass, around fax 3, dragging the wheel 4, which will effect the reassembly of the mainspring. When the mass moves in the direction of the arrow f2, the tooth 5a of the satellite 5 will jump on the different ones. teeth of the wheel 4 like a pawl, thanks to the action of the small spring 13, forming an elastic stop.

Supposons que 1e ressort-moteur soit re mont6 ä fond; lürsque la masse oscillera dans 1e sens de la fleche f, comme la roue 4 ne peut plus tourner autoirr de Faxe 3, 1e satel lite 5 sera force de pivoter sirr lui-meme en agissant sirr 1'extremite 8b du ressort 8, ex tr6mit6 qu'il rapprochera de 1'extremite 8a; lorsque la masse se deplacera "dans 1e sens de la fleche f 2, 1e satellite 5 reviendra en arriere en meine temps que 1e ressort 8 se detendra. Suppose the mainspring is fully wound; when the mass oscillates in the first direction of the arrow f, as the wheel 4 can no longer turn around faxe 3, the first satellite 5 will be forced to pivot on its own by acting on the extremity 8b of the spring 8, ex tr6mit6 that it will bring closer to the end 8a; when the mass moves "in the direction of the arrow f 2, the satellite 5 will come back at the same time as the spring 8 will relax.

En resume, 1e satellite 5 agit sirr 1.e res sort-moteur tant que celui-ei n'est pas re monte; apres quoi, il n'agit plus que sirr 1e ressort B. In summary, the first satellite 5 acts sirr 1.e spring out-engine as it is not re mounted; after which, it only acts on spring B.

Le meca.nisme susdecrit est extrAmement simple, puisque, etant donne qu'il faut d'ha bitude un cliquet et un rochet pour traus mettre 1e mouvement de la masse au baril let, il se Limite, en derniere analys-e, au res sort 8, ä 1'oreille 12 et ä la cheville 11. D'au tre paxt, 1e ressort-lame 8 est tres. bon mar che; en outre, gräce @ä sa forme et gräce au point favorable oiz 1e satellite agzt sirr lui, il peut resister tres longtemps aux efforts aux quels il est soumis. . The mechanism described above is extremely simple, since, given that it usually takes a pawl and a ratchet to convert the movement of the mass to the barrel, it is limited, in the last analysis, to the res spring 8, at the ear 12 and at the ankle 11. On the other hand, the leaf spring 8 is very strong. cheap; moreover, thanks to its shape and thanks to the favorable point where the satellite acts on it, it can withstand the forces to which it is subjected for a very long time. .

Claims

CLAIM Device for the automatic winding of a watch movement, comprising a mobile mass connected by a gear to the mainspring, characterized in that the mass carries, in one bet, a satellite which can oscillate freely on its own and meshing with the first mobile of the gear, mobile around which the mass oscillates, and, on the other hand, a limiting spring on one end of which is fixed with respect to the mass and on the other end of which a member of the satellite vieret abuts when it rotates in the direction of winding, which allows the latter, in this direction, to act on the mainspring as long as the latter is not wound fand, the satellite acting, from this moment , only on the 1st limiting spring. SUB-CLAIMS 1 Device according to claim 1, characterized in that the first limiting spring is constituted by a laure in the form of an arc of a circle, housed in a corresponding hollow of the mass, from which emerges the extreme mit6 of the spring serving as a stop to satellite lite.
