Description

La présente invention a pour objet un dispositif d'étanchéité pour un organe de commande traversant la paroi d'une boîte de montre telle qu'une couronne de remontoir ou un poussoir par exemple.The present invention relates to a sealing device for a control member passing through the wall of a watch case such as a winding crown or a pusher for example.

Le but de la présente invention est la réalisation d'un dispositif d'étanchéité pour un organe de commande traversant la paroi d'une boîte de montre qui permette d'assurer une étanchéité normale, par exemple résistant à 10 Atm, pendant l'utilisation de l'organe de commande et une étanchéité accrue lorsque l'organe de commande n'est pas utilisé, par exemple résistant à 100 Atm.The object of the present invention is the realization of a sealing device for a control member passing through the wall of a watch case which makes it possible to ensure a normal seal, for example resistant to 10 Atm, during use. of the control member and increased sealing when the control member is not used, for example resistant to 100 Atm.

Un autre but de la présente invention est d'éviter, lors du passage de l'étanchéité normale à l'étanchéité accrue, tout déplacement angulaire et/ou axial de l'organe de commande pour éviter toute interaction avec le mécanisme commandé.Another object of the present invention is to avoid, during the transition from normal sealing to increased sealing, any angular and / or axial displacement of the control member to avoid any interaction with the controlled mechanism.

Encore un autre but de l'invention est de réaliser un tel dispositif d'étanchéité qui soit simple à fabriquer et à monter et qui puisse être facilement démonté par le service après-vente, par exemple pour changer les joints.Yet another object of the invention is to provide such a sealing device which is simple to manufacture and assemble and which can be easily dismantled by the after-sales service, for example to change the seals.

La présente invention a pour objet un dispositif d'étanchéité pour un organe de commande traversant une boîte de montre qui obvie aux inconvénients des dispositifs existants et permette d'atteindre les buts énoncés ci-dessus, ce dispositif d'étanchéité se distinguant par les caractéristiques énoncées à la revendication 1.The present invention relates to a sealing device for a control member passing through a watch case which obviates the drawbacks of the existing devices and makes it possible to achieve the aims stated above, this sealing device being distinguished by the characteristics set forth in claim 1.

La figure 8 illustre en coupe une troisième forme d'exécution du dispositif d'étanchéité.Figure 8 illustrates in section a third embodiment of the sealing device.

Les figures 9 et 10 illustrent en coupe des variantes de la forme d'exécution illustrée à la figure 8.Figures 9 and 10 illustrate in section variants of the embodiment illustrated in Figure 8.

Le présent dispositif d'étanchéité pour un organe de commande traversant une boîte en particulier une boîte de montre s'applique aussi bien à des poussoirs que plus particulièrement à une tige ou couronne de remontoir. Ce dispositif permet d'augmenter considérablement l'étanchéité de l'organe de commande. A l'aide de ce dispositif, l'étanchéité normale d'environ 10 Atm qui est présente lors des manipulations de l'organe de commande peut être augmentée à une valeur de l'ordre de 100 Atm par une simple manipulation d'une clé de compression, manipulation qui immobilise également l'organe de commande dans sa position inactive.The present sealing device for a control member passing through a box, in particular a watch case, applies both to pushers and more particularly to a stem or winding crown. This device makes it possible to considerably increase the tightness of the control member. With the aid of this device, the normal tightness of about 10 Atm which is present during the manipulations of the control member can be increased to a value of the order of 100 Atm by a simple manipulation of a key compression, manipulation which also immobilizes the control member in its inactive position.

De plus, comme on le verra plus loin, ce dispositif d'étanchéité est facile à fabriquer et à monter sur une boîte étanche car il ne comporte que peu de pièces faciles à usiner. De plus le service après-vente est simplifié car le démontage du dispositif, notamment pour changer les joints, peut se faire facilement sans retour en usine par un horloger présent sur le point de vente.In addition, as discussed below, this sealing device is easy to manufacture and mount on a sealed box because it has only few parts easy to machine. Moreover the after-sales service is simplified because the disassembly of the device, in particular to change the joints, can be done easily without return in factory by a watchmaker present at the point of sale.

Le dispositif d'étanchéité selon la présente invention est illustré au dessin annexé en relation avec l'étanchéité d'une couronne de remontoir et comporte un tube 1 comportant une partie intérieure cylindrique et une partie extérieure cylindrique de plus grand diamètre munie d'un filetage 2. Dans sa moitié inférieure, ce tube 1 comporte un alésage cylindrique tandis que dans sa partie supérieure le tube 1 présente un vide central conique allant en s'évasant vers l'extrémité extérieure du tube 1.The sealing device according to the present invention is illustrated in the accompanying drawing in connection with the sealing of a winding crown and comprises a tube 1 having a cylindrical inner portion and a cylindrical outer portion of larger diameter provided with a thread. 2. In its lower half, this tube 1 has a cylindrical bore while in its part the upper tube 1 has a conical central void flowing towards the outer end of the tube 1.

En position de service l'extrémité interne cylindrique de petit diamètre est chassée à force dans un alésage 3 traversant la boîte étanche 4. Sous le filetage 2 le tube 1 comporte encore une gorge annulaire dans laquelle est placé un joint O-ring 5 coopérant avec ce tube 1, avec la face extérieure de la boîte 4 et, comme on le verra plus loin, avec la clé de compression 6.In the service position the cylindrical inner end of small diameter is forced out in a bore 3 passing through the sealed box 4. Under the thread 2 the tube 1 further comprises an annular groove in which is placed an O-ring 5 cooperating with this tube 1, with the outer face of the box 4 and, as discussed below, with the compression key 6.

La clé de compression 6 de la première forme d'exécution illustrée aux figures 1 à 6 comporte un corps muni d'un filetage interne correspondant au filetage 2 du tube et vissé sur celui-ci. Ce corps est muni d'une cheminée 7 dont la face interne coopère avec le joint 5 et d'une partie supérieure 8 présentant la forme d'une couronne dont la face inférieure présente une partie conique. Le corps de cette clé de compression 6 comporte encore deux ailettes externes 9 permettant sa manipulation par l'usager.The compression key 6 of the first embodiment illustrated in Figures 1 to 6 comprises a body provided with an internal thread corresponding to the thread 2 of the tube and screwed thereon. This body is provided with a chimney 7 whose inner face cooperates with the seal 5 and an upper portion 8 having the shape of a ring whose lower face has a conical portion. The body of this compression key 6 further comprises two external fins 9 allowing its manipulation by the user.

Ainsi lorsque le tube 1 est chassé dans l'alésage 3 de la boîte 4 et que la clé de compression 6 est vissée sur ce tube, le joint 5 assure une étanchéité entre la clé de compression 6 et le tube 1 et en protège le filetage 2. De plus ce joint 5 assure une certaine friction entre le tube 1 et la clé de compression pour que celle-ci ne se déplace pas intempestivement, mais seulement sous l'effet d'un couple que l'usager lui imprime.Thus when the tube 1 is driven into the bore 3 of the box 4 and the compression key 6 is screwed onto this tube, the seal 5 provides a seal between the compression key 6 and the tube 1 and protects the thread 2. In addition, this seal 5 ensures a certain friction between the tube 1 and the compression key so that it does not move unexpectedly, but only under the effect of a torque that the user prints to him.

Comme on le voit aux figures 3, 5 et 6, la cheminée 7 de la clé de compression 6 est fraisée sur 180° environ de sa périphérie de manière à créer deux butées 10, 11 destinées à coopérer avec la tête d'une vis 12 vissée dans la boîte de montre et limitant ainsi la rotation de la clé de compression à environ 180°. La périphérie de la clé de compression 6 comporte un évidement 13 permettant d'accéder à la tête de la vis 12 pour la mettre en place ou la retirer pour le démontage du dispositif d'étanchéité et le remplacement des joints.As seen in Figures 3, 5 and 6, the stack 7 of the compression key 6 is milled about 180 ° from its periphery so as to create two stops 10, 11 for cooperating with the head of a screw 12 screwed into the watch case and thus limiting the rotation of the compression key to about 180 °. The periphery of the compression key 6 has a recess 13 allowing access to the head of the screw 12 for putting it in place or removing it for disassembling the sealing device and replacing the seals.

La vis 12 constitue un arrêt coopérant avec les butées 10, 11 de la clé de compression pour limiter la rotation de celle-ci entre une position ouverte et une position fermée.The screw 12 is a stop cooperating with the stops 10, 11 of the compression key to limit the rotation thereof between an open position and a closed position.

Le dispositif d'étanchéité comporte encore une bague fendue, de préférence en Delrin ou en acier, de forme conique, logée dans la partie étroite du cône intérieur du tube 1. Sur cette bague 14 est disposé un joint O-ring 15 dont la partie supérieure est en appui sous la partie supérieure 8 de la clé de compression.The sealing device further comprises a slotted ring, preferably in Delrin or steel, of conical shape, housed in the narrow part of the inner cone of the tube 1. On this ring 14 is disposed an O-ring 15 whose part upper is supported under the upper part 8 of the compression key.

En position ouverte, dévissée, de la clé de compression 6, ce joint 15 n'est que partiellement comprimé (figure 2) tandis qu'en position fermée, vissée, de la clé de compression, ce joint 15 est totalement comprimé (figure 1) entre la partie supérieure 8 de la clé de compression, le tube 1, la bague 14 et la tige 16 de la couronne 17.In the open position, unscrewed, of the compression key 6, this seal 15 is only partially compressed (FIG. 2) whereas in the closed, screwed position of the compression key, this seal 15 is completely compressed (FIG. ) between the upper part 8 of the compression key, the tube 1, the ring 14 and the rod 16 of the ring 17.

La couronne de remontoir 17 comporte une tige 16 traversant la partie supérieure 8 de la clé de compression 6, la bague 14 et la partie cylindrique du tube 1. L'extrémité de la tige 16 de la couronne 17 est munie de deux joints O-ring 18, 19 logés dans une gorge circulaire pratiquée dans la paroi cylindrique externe de la tige 16. Ces joints 18, 19 assurent l'étanchéité normale de l'ordre de 10 Atm. entre le tube 1 et la tige 16 lorsque la clé de compression est ouverte. Dans cette position l'usager peut actionner la tige de remontoir 16 axialement et en rotation.The winding crown 17 comprises a rod 16 passing through the upper part 8 of the compression key 6, the ring 14 and the cylindrical part of the tube 1. The end of the rod 16 of the crown 17 is provided with two O-rings. ring 18, 19 housed in a circular groove formed in the outer cylindrical wall of the rod 16. These seals 18, 19 provide normal sealing of the order of 10 Atm. between the tube 1 and the rod 16 when the compression key is open. In this position, the user can actuate the winding stem 16 axially and in rotation.

Lorsque la clé de compression est vissée ou fermée, le joint 15 est totalement comprimé et force la bague fendue au fond du cône du tube 1 et contre la tige de remontoir 16. Dans cette position l'étanchéité est très nettement accrue et atteint une valeur de 100 Atm et la tige 14 est bloquée.When the compression key is screwed or closed, the seal 15 is fully compressed and forces the split ring at the bottom of the cone of the tube 1 and against the winding stem 16. In this position the seal is very significantly increased and reaches a value 100 Atm and the rod 14 is blocked.

La tige 16 de la couronne de remontoir comporte de façon conventionnelle un filetage axial dans son extrémité interne permettant de l'accoupler à la tige de remontoir proprement dite du mécanisme.The stem 16 of the winding crown conventionally comprises an axial thread in its inner end for coupling it to the actual winding stem of the mechanism.

Grâce à ce mécanisme d'étanchéité, on réalise une étanchéité élevée, 100 Atm, en position fermée de la clé de compression et le remontoir est bloqué. La montre peut être portée dans cette position et ce n'est que lors du remontage ou de la mise à l'heure du mouvement que l'usager libère la clé de compression pour permettre ces fonctions. Dans cette position ouverte l'étanchéité est néanmoins garantie à une valeur normale de l'ordre de 10 Atm.Thanks to this sealing mechanism, it achieves a high seal, 100 Atm, in the closed position of the compression key and the winding is blocked. The The watch can be worn in this position and it is only during reassembly or setting the time of the movement that the user releases the compression key to allow these functions. In this open position the seal is nevertheless guaranteed to a normal value of the order of 10 Atm.

Un avantage supplémentaire du dispositif d'étanchéité réside dans le fait que lors du passage de la position ouverte à la position fermée de la clé de compression et vice-versa, la tige 16 de la couronne 17 ne subit aucun déplacement axial qui pourrait endommager le mécanisme.An additional advantage of the sealing device lies in the fact that during the transition from the open position to the closed position of the compression key and vice versa, the rod 16 of the ring 17 undergoes no axial displacement which could damage the mechanism.

De plus si le pas de vis utilisé pour visser la clé de compression sur le tube comporte un pas à gauche, le serrage de cette clé de compression, même si l'usager tourne simultanément la couronne 17, ce qui peut arriver par inadvertance, le mécanisme ne peut pas être endommagé. En effet la rotation pour le serrage de la clé de compression se fait dans le sens inverse de la rotation de la couronne 17 pour le remontage de la montre. On ne risque ainsi jamais de provoquer une surtension du ressort de barillet.In addition, if the thread used to screw the compression key on the tube has a step to the left, the tightening of the compression key, even if the user simultaneously rotates the crown 17, which may inadvertently happen, the mechanism can not be damaged. Indeed the rotation for tightening the compression key is in the opposite direction of the rotation of the ring 17 for reassembly of the watch. This is never likely to cause overvoltage of the mainspring.

Dans la seconde forme d'exécution du dispositif d'étanchéité illustrée à la figure 7, la clé de compression 6 ne comporte pas d'ailette 9 mais un organe de manoeuvre est constitué par une couronne crantée. Dans cette exécution le tube 1 comportant le filetage 2 comporte un passage central cylindrique sur toute sa longueur et le joint 15 est logé entre la surface terminale externe du tube 1, la partie supérieure 8 de la clé de compression 6 et la tige 16 de la couronne 17. Dans cette exécution le joint de compression 15 est monté sans la bague fendue 17.In the second embodiment of the sealing device illustrated in Figure 7, the compression key 6 does not have fin 9, but an operating member is constituted by a toothed ring. In this embodiment the tube 1 comprising the thread 2 has a central cylindrical passage over its entire length and the seal 15 is housed between the outer end surface of the tube 1, the upper part 8 of the compression key 6 and the rod 16 of the In this embodiment, the compression seal 15 is mounted without the split ring 17.

Dans la troisième forme d'exécution illustrée à la figure 8, l'organe de manoeuvre de la clé de compression 6 est formé par un cône mors ou strié et la couronne 17 est montée sur la tige 16 de manière à pouvoir coulisser axialement contre l'action d'un ressort 20 par l'intermédiaire d'une bague 21 chassée dans la couronne 17 servant de butée axiale. La jupe de la couronne 17 comporte un cône interne correspondant au cône externe de la clé de compression. Ainsi lorsque l'usager appuie sur la couronne 17 contre l'action du ressort 20, il peut entraîner en rotation la clé de compression 6 à l'aide de la couronne 17 par l'accouplement des deux cônes.In the third embodiment illustrated in FIG. 8, the actuating member of the compression key 6 is formed by a jaw or striated cone and the ring 17 is mounted on the rod 16 so as to be able to slide axially against the action of a spring 20 by means of a ring 21 driven into the ring 17 acting as an axial stop. The skirt of the ring 17 has an internal cone corresponding to the outer cone of the compression key. So when the user presses the ring 17 against the action of the spring 20, it can rotate the compression key 6 with the aid of the ring 17 by coupling the two cones.

Dans les variantes illustrées aux figures 9 et 10, l'entraînement de la clé de compression 6 par la couronne 17 s'effectue par des ailettes ou par des six pans s'accouplant lorsque la couronne 17 est appuyée contre l'action du ressort 20.In the variants illustrated in Figures 9 and 10, the drive of the compression key 6 by the ring 17 is effected by fins or by hexagon coupling when the ring 17 is pressed against the action of the spring 20 .

Dans ces trois dernières exécutions (fig. 8-10) la couronne 17 est axialement déplaçable contre l'action d'un ressort 20 par rapport à la tige 16 et ce mouvement axial enclenche et déclenche un accouplement d'entraînement entre la couronne 17 ou la bague 21 qui lui est solidaire et la clé de compression 6. L'usager peut ainsi visser ou dévisser la clé de compression en appuyant sur la couronne 17 et en entraînant celle-ci dans un sens ou dans l'autre. Cet accouplement peut être réalisé par des ailettes 22 et des creusures correspondantes 23 (fig. 9) ou par un six pans femelle 24 et un six pans mâle 25 (fig. 10).In these last three embodiments (FIG 8-10) the ring 17 is axially displaceable against the action of a spring 20 relative to the rod 16 and this axial movement engages and triggers a drive coupling between the ring 17 or the ring 21 which is secured to it and the compression key 6. The user can thus screw or unscrew the compression key by pressing the ring 17 and driving it in one direction or the other. This coupling can be achieved by fins 22 and corresponding recesses 23 (FIG 9) or by a hexagon socket 24 and a hexagon socket 25 (FIG 10).
