Abstract

In order to enable a watch movement to be mounted in a case having a back cover integral with its case band, the manual control device of this movement comprises a shaft having a terminal pair of resilient claws. Notches are disposed in the claws and grip a pin disposed diametrically in the central housing of the crown. The body of the crown is manufactured in one piece with a sleeve engaging in a bore of the case band. The movement is inserted with the shaft by presenting in slantwise, then the crown is put into place by forcing the pin between the claws to introduce it into the notches.

Description

La présente invention a pour objet un dispositif de commande manuelle d'un mouvement de montre destiné être logé dans une boîte, comprenant une tige couplée audit mouvement et déplaçable en rotation et en translation par rapport audit mouvement et une couronne comportant une paroi définissant un logement cylindrique coaxial à ladite tige, ladite couronne étant fixée de manière détachable à ladite tige par des moyens de fixation comprenant une paire de griffes élastiques fixées à l'extrémité de ladite tige, une paire d'encoches ménagées en regard l'une de l'autre chacune dans l'une desdites griffes, et un élément de retenue solidaire de ladite couronne et serré élastiquement par lesdites griffes entre lesdites encoches.The subject of the present invention is a device for manual control of a watch movement intended to be housed in a box, comprising a rod coupled to said movement and movable in rotation and in translation relative to said movement and a crown comprising a wall defining a housing. cylindrical coaxial with said rod, said crown being detachably fixed to said rod by fixing means comprising a pair of elastic claws fixed to the end of said rod, a pair of notches arranged opposite one of the each other in one of said claws, and a retaining element integral with said crown and elastically clamped by said claws between said notches.

Dans les boîtes avec fond indépendant, amovible, l'emboîtage et le déboîtage du mouvement de la montre s'exécutent sans la tige de commande de la mise à l'heure et, éventuellement, du calendrier. Celle-ci est mise en place après que le mouvement a été introduit dans la boîte, ou retirée avant de sortir le mouvement de la boîte. La fixation de cette tige au mouvement, dans le premier cas, et sa libération, dans le second, s'effectuent notoirement en actionnant un tenon solidaire de la tirette et qui est accessible uniquement du côté fond du mouvement. Cette opération est aisée lorsque le fond de la boîte peut être enlevé. Dans les boîtes avec fond-carrure, c'est-à-dire dans celles dont le fond et la carrure sont venus de fabrication en une seule pièce, cette opération n'est cependant plus possible.In boxes with an independent, removable base, the movement of the watch is fitted and removed without the time and possibly the calendar control rod. This is put in place after the movement has been introduced into the box, or removed before removing the movement from the box. The attachment of this rod to the movement, in the first case, and its release, in the second, are effected notoriously by actuating a tenon integral with the pull tab and which is accessible only from the bottom side of the movement. This operation is easy when the bottom of the box can be removed. In boxes with case-back, that is to say those in which the case-back and the case came from one-piece production, this operation is however no longer possible.

Le moyen généralement utilisé depuis de nombreuses années pour permettre d'emboîter et de déboîter le mouvement de la montre dans une boîte avec fond-carrure comporte une tige dite "brisée", faite de deux pièces qui peuvent être reliées l'une à l'autre de façon démontable.The means generally used for many years to allow the movement of the watch to be nested and dislocated in a case with case-back has a so-called "broken" rod, made of two parts which can be connected to each other. other in a removable way.

L'une de ces pièces présente une paire de griffes élastiques encochées et l'autre présente au voisinage de son extrémité un bourrelet transversal ou une goupille transversale.One of these parts has a pair of notched elastic claws and the other has in the vicinity of its end a transverse bead or a transverse pin.

L'une de ces pièces est fixée au mouvement de la montre par la tirette, et elle est suffisamment courte pour ne pas pénétrer dans le trou de la carrure permettant le passage de la tige. Cette pièce n'empêche donc pas le déboîtage ou l'emboîtage du mouvement de la montre.One of these parts is fixed to the movement of the watch by the zipper, and it is short enough not to enter the hole in the middle allowing the passage of the rod. This piece therefore does not prevent the disengagement or the interlocking of the watch movement.

L'autre de ces deux pièces est fixée à la couronne, par exemple au moyen d'un filetage disposé à son extrémité et vissé dans un cylindre fileté adéquat fixé au fond du trou central de la couronne.The other of these two parts is fixed to the crown, for example by means of a thread placed at its end and screwed into a suitable threaded cylinder fixed to the bottom of the central hole of the crown.

Ces pièces sont accouplées en poussant fortement la couronne avec sa partie de tige contre l'autre partie de tige de façon à faire passer le bourrelet ou la goupille entre les griffes pour l'amener dans les encoches de ces dernières. Ces deux pièces se séparent en tirant fortement la couronne vers l'extérieur de la boîte.These parts are coupled by strongly pushing the crown with its stem part against the other stem part so as to pass the bead or the pin between the claws to bring it into the notches of the latter. These two parts separate by strongly pulling the crown out of the case.

De telles tiges brisées sont décrites, par exemple, dans les brevets CH-A-180 459 et CH-A-191 764.Such broken rods are described, for example, in patents CH-A-180,459 and CH-A-191,764.

Ce dernier brevet, en particulier, décrit un dispositif dans lequel la couronne comporte un logement ouvert du côté de la boîte de montre, et une tige filetée disposée au centre de ce logement. Une pièce intermédiaire est vissée par une de ses extrémités à cette tige filetée et comporte à son autre extrémité un bourrelet transversal. Ce dernier est serré entre des encoches ménagées dans des griffes élastiques fixées à la partie de la tige qui est solidaire du mouvement de la montre. La pièce intermédiaire mentionnée ci-dessus peut coulisser dans un tube solidaire de la carrure de montre.This latter patent, in particular, describes a device in which the crown comprises an open housing on the side of the watch case, and a threaded rod disposed in the center of this housing. An intermediate piece is screwed at one of its ends to this threaded rod and has at its other end a transverse bead. The latter is clamped between notches formed in elastic claws fixed to the part of the rod which is integral with the movement of the watch. The intermediate piece mentioned above can slide in a tube integral with the middle part of the watch.

Ce dispositif comporte donc un nombre relativement élevé de pièces, et la couronne a une forme compliquée. Le prix de revient de ce dispositif est donc élevé.This device therefore has a relatively high number of parts, and the crown has a complicated shape. The cost price of this device is therefore high.

Le but de la présente invention est de proposer un dispositif du même genre que celui qui vient d'être décrit, mais qui soit meilleur marché que celui-ci grâce au fait qu'il comporte moins de pièces et que, en outre, aucune de ces pièces n'a une forme compliquée.The object of the present invention is to propose a device of the same kind as that which has just been described, but which is cheaper than the latter thanks to the fact that it comprises fewer parts and that, in addition, none of these pieces do have a complicated shape.

Ce but est atteint par le dispositif défini par la revendication 1.This object is achieved by the device defined by claim 1.

D'autres buts et avantages de l'invention apparaîtront à la lecture de la description de deux de ses formes d'exécution qui va suivre. Ces formes d'exécution de l'invention ne sont décrites qu'à titre d'exemples non limitatifs et sont représentées par le dessin annexé dans lequel :

  • la figure 1 est une coupe diamétrale schématique de la première forme d'exécution;
  • la figure 2 est une vue en élévation schématique, dans le sens de la flèche a, de la couronne de la figure 1, et
  • la figure 3 est une coupe diamétrale schématique de la seconde forme d'exécution.
Other objects and advantages of the invention will appear on reading the description of two of its embodiments which will follow. These embodiments of the invention are only described by way of nonlimiting examples and are represented by the appended drawing in which:
  • Figure 1 is a schematic diametral section of the first embodiment;
  • FIG. 2 is a schematic elevation view, in the direction of arrow a, of the crown of FIG. 1, and
  • Figure 3 is a schematic diametral section of the second embodiment.

Le dispositif de commande selon la première forme d'exécution représenté par les figures 1 et 2 comprend une couronne 1, dont le corps 2, extérieur à la carrure 3 de la boîte, est venu de fabrication en une pièce avec un manchon cylindrique 5 et présente un logement cylindrique 4. Une goupille 6 est logée dans un trou 11 percé dans le corps 2 de la couronne 1, et traverse diamétralement le logement 4. La surface extérieure 7 du manchon 5 est soigneusement polie de façon à glisser et tourner librement dans une forure 8, percée à travers la paroi de la carrure 3.The control device according to the first embodiment represented by FIGS. 1 and 2 comprises a crown 1, the body 2 of which, outside the middle part 3 of the case, came from one-piece production with a cylindrical sleeve 5 and has a cylindrical housing 4. A pin 6 is housed in a hole 11 drilled in the body 2 of the crown 1, and passes diametrically through the housing 4. The outer surface 7 of the sleeve 5 is carefully polished so as to slide and rotate freely in a bore 8, drilled through the wall of the middle part 3.

L'étanchéité du passage de la couronne 1 à travers la carrure 3 est assurée par une garniture d'étanchéité 9, de forme torique, qui est logée dans une gorge annulaire 10 de la carrure 3. Si la couronne est massive, par exemple en or, il faudra naturellement veiller que le trou 11, percé à travers la paroi de son corps 2, soit parfaitement obturé par la goupille 6, pour prévenir des infiltrations entre ces deux pièces. En revanche, si la couronne 1 est faite en métal vil, on peut la recouvrir d'une fine coiffe, par exemple en acier inoxydable, pour obturer le passage de la goupille 6 à travers la paroi du corps 2. Dans un tel cas, la goupille 6 doit bien entendu être mise en place avant cette coiffe.The tightness of the passage of the crown 1 through the middle part 3 is ensured by a sealing gasket 9, of toroidal shape, which is housed in an annular groove 10 of the middle part 3. If the crown is solid, for example in however, it will naturally be necessary to ensure that the hole 11, drilled through the wall of its body 2, is perfectly closed by the pin 6, to prevent infiltration between these two parts. On the other hand, if the crown 1 is made of base metal, it can be covered with a thin cap, for example made of stainless steel, to close the passage of the pin 6 through the wall of the body 2. In such a case, the pin 6 must of course be put in place before this cap.

Pour commander certaines fonctions du mouvement 12 de la montre, telles que sa mise à l'heure, le réglage ou la correction du calendrier, une tige 13 est montée de façon usuelle dans le mouvement 12. Elle est retenue dans ce dernier par un plot de tirette (non représenté), qui plonge dans une gorge 14 de la tige 13. L'extrémité de cette dernière qui est extérieure au mouvement 12 présente un filetage 15. Un embout 16 est vissé à fond sur ce filetage 15, de façon à être solidaire de la tige 13.To control certain functions of the watch movement 12, such as setting the time, adjusting or correcting the calendar, a rod 13 is mounted in the usual way in movement 12. It is retained in the latter by a stud zipper (not shown), which plunges into a groove 14 of the rod 13. The end of the latter which is external to the movement 12 has a thread 15. An end piece 16 is screwed fully onto this thread 15, so as to be integral with the rod 13.

Dans une autre forme d'exécution, non représentée, l'extrémité de la tige 13 est lisse et l'embout 16 est chassé et collé sur cette extrémité de manière qu'il soit également solidaire de cette tige 13.In another embodiment, not shown, the end of the rod 13 is smooth and the endpiece 16 is driven out and glued to this end so that it is also integral with this rod 13.

La surface extérieure 17 de l'embout 16 est cylindrique. Elle s'engage librement dans le manchon 5. La surface extérieure 18 de l'extrémité de l'embout 16 est conique et présente une fente diamétrale 19, de façon à former deux griffes élastiques 20. Ces griffes 20 présentent chacune une encoche 21. Ces encoches 21 entourent partiellement la goupille 6 et la retiennent entre elles, de sorte que la couronne 1 est reliée mécaniquement à la tige 13 et que cette dernière est entraînée par tout mouvement de rotation ou de translation imprimé à la couronne 1.The outer surface 17 of the nozzle 16 is cylindrical. It engages freely in the sleeve 5. The outer surface 18 of the end of the endpiece 16 is conical and has a diametrical slot 19, so as to form two elastic claws 20. These claws 20 each have a notch 21. These notches 21 partially surround the pin 6 and hold it between them, so that the crown 1 is mechanically connected to the rod 13 and that the latter is driven by any rotational or translational movement printed on the crown 1.

Bien que l'embout 16, solidaire de la tige 13, s'étende jusqu'à l'extérieur de la carrure 3, le mouvement 12, muni de la tige 13 garnie de l'embout 16, peut être emboîté sans difficulté. Vu l'absence de tube dans la forure 8 de la carrure 3, l'embout 16 passe, en effet, à travers la forure 8 lorsque le mouvement 12 est présenté dans une position inclinée par rapport à la carrure 3. Le déboîtage s'opère en sortant de la boîte d'abord la partie du mouvement 12 qui est diamétralement opposée à la tige 13.Although the endpiece 16, integral with the rod 13, extends to the outside of the middle part 3, the movement 12, provided with the rod 13 furnished with the endpiece 16, can be fitted without difficulty. Given the absence of a tube in the bore 8 of the middle part 3, the end piece 16, in fact, passes through the hole 8 when the movement 12 is presented in an inclined position relative to the middle part 3. The disengagement operates by leaving the box first of all the part of the movement 12 which is diametrically opposite the rod 13.

Pour fixer la couronne 1 à la tige 13 lorsque le mouvement 12 est dans la boîte, il suffit de chapeauter l'embout 16 avec la couronne 1 de manière que la goupille 6 soit parallèle à la fente 19, et de pousser fermement cette couronne 1 en direction de la carrure 3.To fix the crown 1 to the rod 13 when the movement 12 is in the case, it suffices to cap the end piece 16 with the crown 1 so that the pin 6 is parallel to the slot 19, and to firmly push this crown 1 towards the middle 3.

La goupille 6 force alors l'écartement des griffes 20, qui la laissent passer entre elles. La conicité des surfaces 18 des griffes 20 leur permet ce déplacement à l'intérieur du corps 2. La goupille 6 parvient ainsi dans les encoches 21. L'élasticité des griffes 20 provoque alors le rapprochement de ces dernières qui emprisonnent par conséquent la goupille 6 dans les encoches 21.The pin 6 then forces the spacing of the claws 20, which allow it to pass between them. The taper of the surfaces 18 of the claws 20 allows them to move inside the body 2. The pin 6 thus reaches the notches 21. The elasticity of the claws 20 then causes the latter to come together which consequently trap the pin 6 in the notches 21.

Pour faciliter l'orientation de la goupille 6 par rapport à la fente 19 et son introduction entre les griffes 20, un chanfrein 22 est prévu le long de l'arête interne de chacune de ces griffes 20.To facilitate the orientation of the pin 6 relative to the slot 19 and its introduction between the claws 20, a chamfer 22 is provided along the internal edge of each of these claws 20.

Si le mouvement 12 doit être déboîté, la couronne doit au préalable être enlevée. A cet effet, elle est écartée de la carrure 3 avec une force suffisante pour faire repasser la goupille 6 entre les griffes 20, en les écartant l'une de l'autre.If movement 12 has to be disengaged, the crown must first be removed. To this end, it is moved away from the middle part 3 with a force sufficient to iron the pin 6 between the claws 20, moving them apart from one another.

L'élasticité des griffes 20 doit évidemment être déterminée en fonction des caractéristiques des diverses pièces du mouvement 12 qui sont reliées à la tige 13, de manière que la force nécessaire à l'arrachement de la couronne soit supérieure à celle qu'il faut exercer pour amener la couronne 1 de sa position poussée à sa ou à ses positions tirées, mais inférieure à celle que peuvent supporter sans dommage ces diverses pièces du mouvement 12.The elasticity of the claws 20 must obviously be determined according to the characteristics of the various parts of the movement 12 which are connected to the rod 13, so that the force necessary to tear off the crown is greater than that which must be exerted to bring the crown 1 from its pushed position to its pulled position or positions, but less than that which these various parts of the movement 12 can bear without damage.

La seconde forme d'exécution du dispositif selon l'invention, représentée par la figure 3, se distingue de la première uniquement par le fait que la partie 23, qui remplace l'embout 16 de la première forme d'exécution, est ici venue de fabrication en une pièce avec la tige 24.The second embodiment of the device according to the invention, represented by FIG. 3, differs from the first only by the fact that the part 23, which replaces the end piece 16 of the first embodiment, has come here in one piece with rod 24.

Dans cette seconde forme d'exécution, la tige 24 sort donc de fabrication à une longueur déterminée. Or, selon les dimensions de la boîte appelée à recevoir le mouvement, il est nécessaire d'adapter à celle-ci la longueur de la tige. Pour permettre une telle adaptation, il suffit de prévoir la partie 23 assez longue, la fente 19 suffisamment profonde et une rangée d'encoches 21 le long de cette fente.In this second embodiment, the rod 24 therefore leaves production at a determined length. However, depending on the dimensions of the box called to receive the movement, it is necessary to adapt to it the length of the rod. To allow such an adaptation, it suffices to provide the fairly long part 23, the sufficiently deep slot 19 and a row of notches 21 along this slot.

Au lieu de planter la goupille 6 dans le corps 2 de la couronne 1, elle pourrait aussi l'être à travers le manchon 5, en un endroit de celui-ci qui, au moins lorsque la couronne 1 est en position poussée, est situé au-delà de la garniture d'étanchéité 9 en direction de l'intérieur de la boîte. On évite ainsi tout problème d'étanchéité qui pourrait se poser si la goupille 6 ne bouchait pas complètement le trou 11 dans lequel elle est placée. Dans ce cas, il faut bien entendu que le manchon 5 soit suffisamment résistant pour supporter les efforts exercés sur la goupille 6 lors de la mise en place ou de l'enlèvement de la couronne 1.Instead of planting the pin 6 in the body 2 of the crown 1, it could also be through the sleeve 5, in a place thereof which, at least when the crown 1 is in the pushed position, is located beyond the seal 9 towards the inside of the box. This avoids any sealing problem which could arise if the pin 6 did not completely block the hole 11 in which it is placed. In this case, it is understood that the sleeve 5 is strong enough to withstand the forces exerted on the pin 6 during the installation or removal of the crown 1.

Afin d'éviter des déplacements latéraux de l'embout 16 ou de la partie 23 de la tige 24 par rapport à la couronnne 1 au cours de sa rotation, ce qui ferait varier désagréablement le moment à exercer sur la couronne 1, il est indiqué d'ajuster le diamètre de cet embout 16 ou de cette partie 23 de la tige 24 à celui du logement 4 de la couronne.In order to avoid lateral displacements of the end-piece 16 or of the part 23 of the rod 24 with respect to the crown 1 during its rotation, which would cause the moment to be exerted on the crown 1 to vary unpleasantly, it is indicated to adjust the diameter of this end piece 16 or of this part 23 of the rod 24 to that of the housing 4 of the crown.

On voit que dans le dispositif selon l'invention qui vient d'être décrit et tel qu'il est défini par la revendication 1, la couronne est beaucoup plus simple que dans les dispositifs connus puisqu'elle ne présente qu'un logement central cylindrique et une goupille disposée diamétralement dans ce logement. La partie de la tige qui est solidaire de la couronne dans les dispositifs connus et ses moyens de fixation à cette couronne sont donc supprimés.We see that in the device according to the invention which has just been described and as defined by claim 1, the crown is much simpler than in known devices since it has only a central cylindrical housing and a pin arranged diametrically in this housing. The part of the rod which is integral with the crown in known devices and its means of attachment to this crown are therefore eliminated.

La partie solidaire de la tige, qui porte les griffes encochées peut être venue de fabrication en une pièce avec la tige (revendication 2). Elle peut également consister en une pièce indépendante, vissée à l'extrémité de la tige (revendication 3) ou chassée et collée sur cette extrémité de la tige (revendication 4). Les formes spéciales d'exécution défines par la revendication 5 ont l'avantage additionnel de substituer le manchon de la couronne au tube généralement fixé à la boîte dans les montres étanches. L'espace autour de la tige dans la forure de la boîte, qui est libre en l'absence de la couronne, permet d'emboîter et de déboîter le mouvement depuis le côté glace d'une boîte avec fond-carrure. Le mouvement peut, en effet, être placé dans une position oblique à l'entrée de ce fond-carrure. L'étanchéité du passage de cette tige à travers la paroi de la carrure peut être réalisée par une garniture d'étanchéité montée dans un logement de la carrure de façon à ceinturer le manchon de la couronne (revendication 6). Quant à la goupille saisie par les encoches des griffes solidaires de la tige, elle peut être plantée au travers du manchon de la couronne, au-delà de la garniture d'étanchéité, vers l'intérieur de la boîte, si une fuite est à craindre entre cette goupille et la paroi de la couronne (revendication 7). Enfin, selon la position choisie de la goupille solidaire de la couronne ou si le dispositif de commande doit pouvoir être monté sur des boîtes de différentes dimensions, plusieurs encoches peuvent être prévues dans des griffes assez longues (revendication 8). Au besoin, les extrémités de ces griffes pourront être éliminées.The integral part of the rod, which carries the notched claws, may have been manufactured in one piece with the rod (claim 2). It can also consist of an independent part, screwed to the end of the rod (claim 3) or driven out and glued to this end of the rod (claim 4). The special embodiments defined by claim 5 have the additional advantage of substituting the crown sleeve for the tube generally fixed to the case in waterproof watches. The space around the rod in the hole in the case, which is free in the absence of the crown, allows the movement to be nested and dislodged from the glass side of a case with case back. The movement can, in fact, be placed in an oblique position at the entrance to this back-middle. The passage of this rod through the wall of the middle part can be sealed by a seal fitted in a housing of the middle part so as to encircle the sleeve of the crown (claim 6). As for the pin gripped by the notches of the claws integral with the rod, it can be planted through the sleeve of the crown, beyond the seal, towards the inside of the box, if a leak is to be fear between this pin and the wall of the crown (claim 7). Finally, depending on the chosen position of the pin secured to the crown or if the control device must be able to be mounted on boxes of different dimensions, several notches can be provided in fairly long claws (claim 8). If necessary, the ends of these claws can be removed.

Bien que le dispositif de commande décrit soit particulièrement avantageux dans le cas où le mouvement de la montre est destiné à être monté dans une boîte avec fond-carrure, rien ne s'oppose, bien entendu, à son utilisation dans le cas où le mouvement de la montre est destiné à être monté dans une boîte avec fond indépendant.Although the control device described is particularly advantageous in the case where the movement of the watch is intended to be mounted in a box with case back, of course, nothing prevents its use in the case where the movement of the watch is intended to be mounted in a box with independent bottom.
