Description

  

  Montre-bracelet à remontage automatique.    La présente invention se rapporte à une  montre-bracelet à remontage automatique  qui est caractérisée par un cadre rigide au  quel est attaché le bracelet, par une montre  proprement dite montée dans le cadre, sur un  axe parallèle à l'axe longitudinal du poignet,  et par un organe que les déplacements rela  tifs de la montre proprement dite et du ca  dre actionnent et qui, à son tour, remonte le       ressort-moteur.     



  Le dessin ci-annexé représente,     à,    titre  d'exemple, une forme d'exécution de l'objet  de l'invention.  



  La fi-. 1 est une vue en plan d'une  montre-bracelet;  La     fig.    2 est une vue en élévation de la  montre;  La     fig.    3 est une coupe horizontale vue  du côté des ponts;  La     fig.    4 est une vue en     perspective     d'une partie du mécanisme de remontage.  Dans la forme d'exécution représentée.,  le mouvement 1 est logé dans une boîte 2,    de forme rectangulaire, montée     rotativement     sur     ûn    arbre 3 parallèle à l'axe longitudi  nal du poignet et qui traverse des oreilles  4, solidaires de la platine 5.

   Cet arbre est  fixé, par ses deux extrémités carrées 6, dans  un cadre constitué par les deux barres 7 re  liées entre elles par des     traverses    8 portant le  bracelet 9.  



  A une certaine distance au-dessous de  l'arbre 3 est disposé un levier 10, articulé  sur une cheville 11, porté, par exemple, par  un pont 12. L'une des extrémités du levier  forme une     fourchette    18 qui s'engage sur  une cheville 14 solidaire de l'arbre 3. A  l'autre extrémité du levier 10 est     articulé     un cliquet 15 coopérant avec un rochet 16  qui est relié au barillet. Un ressort 17 main  tient le     cliquet    en prise avec le rochet. 13  est un     cliquet    de retenue. Un ressort 19 agit  sur le levier 10 et tend à le maintenir dans  la position représentée.  



  Lorsque la montre est mise en place, la  boîte 2 repose sur le poignet du porteur.      Tout mouvement de la main provoque des  mouvements des muscles du poignet, et cer  tains de ces mouvements provoquent une  pression des muscles sur la boîte 2 et feront  basculer la boîte sur l'arbre     â,    par rapport  au cadre, dans le sens de la flèche     f.    Le point  de pivotement du levier 10 sur la     cheville    11  se déplace alors par rapport au point d'ap  pui du levier sur la cheville 14 qui reste  fixe, ce qui provoque une     oscillation    du le  vier dans le sens de la flèche     f    , et le cliquet  15 fera avancer le rochet 16 dans le sens du  remontage du ressort-moteur.

   Dès que la  main prend sa position normale par rapport  au bras et que la pression des muscles sur  la boîte 2 cesse, celle-ci, sous l'influence de  son poids et du ressort 19 tendant à rame  ner le levier 10 en arrière, prend sa     positioD     normale sur le poignet, le cliquet 15 revenant  en glissant sur les dents du rochet pendant  ce mouvement de la boîte 2.  



  Deux talons 20 portés par     1a_    boîte 2 li  mitent l'amplitude de son mouvement     d'os-          cillation    par rapport à son support. Pour  éviter une surtension du ressort-moteur, le  barillet sera muni d'un dispositif de     sûreté.  



  Self-winding wristwatch. The present invention relates to a self-winding wristwatch which is characterized by a rigid frame to which the bracelet is attached, by a watch proper mounted in the frame, on an axis parallel to the longitudinal axis of the wrist, and by a member that the relative movements of the watch proper and of the frame actuate and which, in turn, winds the mainspring.



  The accompanying drawing represents, by way of example, one embodiment of the object of the invention.



  The fi-. 1 is a plan view of a wristwatch; Fig. 2 is an elevational view of the watch; Fig. 3 is a horizontal section seen from the side of the bridges; Fig. 4 is a perspective view of part of the winding mechanism. In the embodiment shown., The movement 1 is housed in a box 2, of rectangular shape, rotatably mounted on a shaft 3 parallel to the longitudi nal axis of the wrist and which passes through the ears 4, integral with the plate 5. .

   This shaft is fixed, by its two square ends 6, in a frame formed by the two bars 7 re linked together by crossbars 8 carrying the bracelet 9.



  At a certain distance below the shaft 3 is arranged a lever 10, articulated on a pin 11, carried, for example, by a bridge 12. One of the ends of the lever forms a fork 18 which engages on a pin 14 integral with the shaft 3. At the other end of the lever 10 is articulated a pawl 15 cooperating with a ratchet 16 which is connected to the barrel. A hand spring 17 holds the pawl in engagement with the ratchet. 13 is a retaining pawl. A spring 19 acts on the lever 10 and tends to hold it in the position shown.



  When the watch is in place, the box 2 rests on the wearer's wrist. Any movement of the hand causes movements of the muscles of the wrist, and some of these movements cause muscle pressure on the gearbox 2 and will cause the gearbox to tip over the shaft â, relative to the frame, in the direction of the arrow. f. The pivot point of the lever 10 on the pin 11 then moves relative to the point of support of the lever on the pin 14 which remains fixed, which causes an oscillation of the lever in the direction of the arrow f, and the pawl 15 will advance ratchet 16 in the direction of winding of the mainspring.

   As soon as the hand assumes its normal position with respect to the arm and the pressure of the muscles on the box 2 ceases, the latter, under the influence of its weight and of the spring 19 tending to pull the lever 10 backwards, takes its normal position on the wrist, the pawl 15 sliding back on the teeth of the ratchet during this movement of the box 2.



  Two heels 20 carried by the box 2 li mitigate the amplitude of its oscillating movement relative to its support. To avoid overvoltage of the mainspring, the barrel will be fitted with a safety device.
