Abstract

The structure has a sealing joint (22) with relatively less thickness and including two lips (22a, 22b). The lips form a housing (24) in which a helical spring (26) is disposed. The housing is opened outwards of a watch case so that, if a watch is plunged into water, pressure generated by the case tends to place the lips against contact surfaces of a tube (10) and a crown (12) using the helical spring.

Description

La présente invention se rapporte à une garniture étanche pour montre, du type comportant une pièce mobile en translation, à l'instar d'une couronne de mise à l'heure ou d'un poussoir, une pièce solidaire de la boíte et un joint d'étanchéité intercalé entre la pièce mobile et la pièce fixe. De manière plus précise, les pièces fixe et mobile présentent des surfaces entre lesquelles est interposé le joint d'étanchéité. Une telle solution est largement mise en oeuvre dans les montres, le joint étant généralement de forme torique à section ronde. La qualité de l'étanchéité ainsi obtenue est fonction de la structure des pièces et de la qualité du joint. Dans tous les cas, si la pression du joint sur les pièces est insuffisante, le risque est grand de voir la garniture ne pas assurer l'étanchéité attendue.The present invention relates to a waterproof seal for a watch, type comprising a moving part in translation, like a crown of set time or a pusher, a piece secured to the box and a seal seal inserted between the movable part and the fixed part. More precise, the fixed and mobile parts have surfaces between which is interposed the seal. Such a solution is widely implemented in watches, the seal being generally ring-shaped with a section round. The quality of the seal thus obtained is a function of the structure of the parts and seal quality. In any case, if the seal pressure on the parts is insufficient, the risk is great to see the filling does not ensure the expected tightness.

Le but de la présente invention est d'améliorer cette situation. A cet effet, le joint comporte deux lèvres reliées entre elles par l'une de leurs extrémités, l'autre extrémité étant en contact avec les surfaces des pièces fixe et mobile, lesdites lèvres étant disposées de manière à former entre elles un logement ouvert vers l'extérieur de la boíte et dans lequel est disposé un organe élastique appliquant les lèvres contre les surfaces. Le joint, bien qu'étant d'une épaisseur relativement faible, assure ainsi une étanchéité de qualité grâce au fait que l'organe élastique applique les lèvres contre les surfaces de contact des pièces fixe et mobile, engendrant ainsi une pression nettement supérieure à celle propre au matériau constitutif du joint. En outre, du fait que le logement est ouvert vers l'extérieur de la boíte, lorsque la boíte est soumise à une pression extérieure, la montre étant par exemple plongée dans l'eau, les lèvres sont appliquées avec plus de force contre leurs surfaces de contact.The object of the present invention is to improve this situation. For this purpose, joint comprises two lips interconnected by one of their ends, the other end being in contact with the surfaces of the fixed and moving parts, said lips being arranged so as to form between them a housing open to the outside of the box and in which is disposed an organ elastic applying the lips against the surfaces. The seal, although being a relatively low thickness, thus ensuring a quality seal thanks to the fact that the elastic member applies the lips against the surfaces of contact of the fixed and moving parts, thus generating a distinct pressure greater than that specific to the material constituting the seal. In addition, because the housing is open towards the outside of the box, when the box is subjected to an external pressure, the watch being for example diving in the water, the lips are applied with greater force against their contact surfaces.

Dans un premier mode de réalisation, la pièce mobile est formée d'une couronne de mise à l'heure et la pièce fixe d'un tube solidaire de la boíte. Avantageusement, les surfaces sont cylindriques et coaxiales à la couronne. In a first embodiment, the moving part is formed of a setting crown and the fixed part of a tube integral with the box. Advantageously, the surfaces are cylindrical and coaxial with the ring.

L'expérience montre que, bien que la couronne soit à la fois soumise à des mouvements de translation et de rotation, la qualité du contact reste bonne et garantit de bonnes conditions de travail dans le temps.Experience shows that although the crown is both subject to translational and rotational movements, the quality of contact remains good and guarantees good working conditions over time.

La couronne porte une bague définissant une gorge dans laquelle est disposé ledit joint dont le logement est ouvert sur la bague. De la sorte, le joint est parfaitement maintenu en place, sans affecter ses conditions de travail.The crown carries a ring defining a groove in which is disposed said seal whose housing is open on the ring. In this way, the seal is perfectly maintained in place, without affecting its working conditions.

Dans un deuxième mode de réalisation, la couronne comporte une portion logée dans le tube et munie d'une gorge cylindrique s'étendant radialement vers l'extérieur, et à l'intérieur de laquelle est disposé le joint, ses lèvres étant respectivement en appui contre les faces du tube et de la gorge.In a second embodiment, the crown comprises a portion housed in the tube and provided with a radially extending cylindrical groove outward, and inside which is arranged the seal, his lips being respectively in support against the faces of the tube and the groove.

Dans un troisième mode de réalisation, la pièce mobile est un poussoir et ladite pièce fixe un tube solidaire de la boíte. Les surfaces de contact, sur lesquelles les lèvres prennent appui, sont planes et parallèles entre elles, et perpendiculaires à l'axe.In a third embodiment, the moving part is a pusher and said piece fixes a tube integral with the box. Contact surfaces, on which the lips support, are flat and parallel to each other, and perpendicular to the axis.

Afin d'assurer un bon positionnement du joint, la surface dont est muni le tube est limitée par des collerettes le positionnant radialement.In order to ensure a good positioning of the seal, the surface of which the tube is provided is limited by flanges positioning it radially.

On connaít certes déjà une solution similaire, décrite dans la demande de brevet WO2004046831. Dans ce cas, le joint est associé à une lunette tournante. Les problèmes que pose cette dernière diffèrent sensiblement de ceux rencontrés avec une couronne ou un poussoir, dès lors que ceux-ci doivent pouvoir être déplacés axialement. En outre, le diamètre du joint est beaucoup plus faible que pour la lunette. Rien ne laisse supposer qu'une structure telle que revendiquée peut être appliquée avec succès à ce type de composants.We already know a similar solution, described in the application for WO2004046831. In this case, the seal is associated with a telescope rotating. The problems posed by the latter differ significantly from those encountered with a crown or a pusher, as long as these must be able to be moved axially. In addition, the diameter of the joint is much lower than for the telescope. Nothing suggests that structure as claimed can be successfully applied to this type of components.

La description sera mieux comprise à la lecture de la description qui va suivre, donnée à titre d'exemple et faite en référence au dessin dans lequel les figures 1 et 2, d'une part, et 3, d'autre part, sont des vues en coupe de garnitures d'étanchéité selon l'invention, équipant respectivement une couronne de mise à l'heure, et un poussoir. The description will be better understood by reading the description that will follow, given as an example and made with reference to the drawing in which Figures 1 and 2, on the one hand, and 3, on the other hand, are sectional views of seals according to the invention, respectively equipping a setting crown, and a pusher.

La garniture d'étanchéité représentée à la figure 1 est destinée à équiper une boíte non représentée au dessin et qui porte un tube 10 fixé rigidement et de manière étanche à la paroi de la boíte. Ce tube traverse la boíte de part en part et s'ouvre à la fois vers l'intérieur et vers l'extérieur de la boíte II comporte une face externe 10a cylindrique dans sa portion médiane et présente une portion conique 10b à son extrémité opposée à celle fixée à la boíte. Il est destiné à permettre le passage d'une tige permettant commander la mise à l'heure de la montre. Cette fonction est assurée par une couronne 12 engagée sur le tube 10 et susceptible de tourner autour d'un axe A-A confondu avec l'axe du tube. La couronne 12 et le tube 10 définissent entre eux un espace ouvert à la fois vers l'intérieur et vers l'extérieur de la boíte qui, s'il n'est pas obturé, pourrait permettre à des impuretés d'y pénétrer.The seal shown in Figure 1 is intended to equip a box not shown in the drawing and which carries a rigidly fixed tube 10 and waterproof way to the wall of the box. This tube passes through the box of part in part and opens at the same time towards the inside and the outside of box II has an outer cylindrical face 10a in its middle portion and has a conical portion 10b at its end opposite to that fixed at box. It is intended to allow the passage of a rod for controlling setting the time of the watch. This function is provided by a crown 12 engaged on the tube 10 and capable of rotating about an axis A-A confused with the axis of the tube. The ring 12 and the tube 10 define between them an open space at the same time towards the inside and the outside of the box which, if not closed, could allow impurities to enter.

La couronne 12 est solidaire d'une bague 13 fixée par collage ou soudage, au travers de laquelle le tube 10 est engagé. Elle est munie, dans sa portion centrale, d'un trou taraudé 14 coaxial à l'axe A-A et destiné à recevoir la tige de mise à l'heure. Une gorge 16, dans laquelle est engagé le tube 10, entoure la portion centrale de la couronne 12. La couronne 12 comporte, en outre, une paroi 18 cylindrique dont la face interne 18a s'étend concentriquement au tube 10 et à la portion centrale, formant entre eux une gorge annulaire 20 partiellement fermée côté boíte par la bague 13. Cette dernière abrite un joint d'étanchéité 22 avantageusement en caoutchouc. Un dégagement circulaire 21 pratiqué à l'extrémité de la face interne 18a de la couronne 12 permet de recevoir la bague 13 venant obturer l'ouverture annulaire 20 et maintenir le joint d'étanchéité 22 dans celle-ci.The ring 12 is secured to a ring 13 fixed by gluing or welding, to through which the tube 10 is engaged. It is provided, in its portion central, a tapped hole 14 coaxial with the axis A-A and for receiving the rod setting time. A groove 16, in which the tube 10 is engaged, surrounds the central portion of the crown 12. The crown 12 comprises, in in addition, a cylindrical wall 18 whose inner face 18a extends concentrically to the tube 10 and to the central portion, forming between them a annular groove 20 partially closed box side by the ring 13. This the last houses a seal 22 advantageously rubber. A circular clearance 21 made at the end of the inner face 18a of the 12 crown can receive the ring 13 from closing the opening annular 20 and maintain the seal 22 therein.

Le joint d'étanchéité 22 comprend deux lèvres 22a et 22b reliées l'une à l'autre par l'une de leurs extrémités et en contact respectivement avec les faces 10a et 18a, qui sont concentriques. Les lèvres 22a et 22b définissent ensemble un logement 24 dans lequel est disposé un organe élastique 26 en appui contre les parois du logement et tendant à appliquer les lèvres contre les faces 10a et 18a. The seal 22 comprises two lips 22a and 22b connected to each other. the other by one of their ends and in contact respectively with the faces 10a and 18a, which are concentric. The lips 22a and 22b define together a housing 24 in which is disposed an elastic member 26 in support against the walls of the housing and tending to apply the lips against the faces 10a and 18a.

Le logement 24 est ouvert vers l'extérieur de la boíte, de telle sorte que, si la montre est plongée dans l'eau, la pression engendrée par cette dernière tendra à appliquer les lèvres 22a et 22b contre les parois 10a et 18a, renforçant ainsi l'étanchéité.The housing 24 is open towards the outside of the box, so that, if the watch is immersed in water, the pressure generated by it will tend to apply the lips 22a and 22b against the walls 10a and 18a, thus reinforcing the tightness.

On relèvera, en outre, que la portion conique 10b du tube 10 facilite la mise en place de la couronne 12 sur le tube 10 et évite que la lèvre 22a ne se déforme.It will be noted, moreover, that the conical portion 10b of the tube 10 facilitates the setting in place of the ring 12 on the tube 10 and prevents the lip 22a from deformed.

L'organe élastique peut être du type des ressorts à boudin, comme proposé par les joints d'étanchéité commercialisés par la maison Bal Seal (USA). Il assure un maintien en place du joint, bien que celui-ci ne présente qu'une faible épaisseur.The elastic member may be of the type of coil springs, as proposed by the seals marketed by the Bal Seal House (USA). he ensures that the seal is held in place, even though it only shows one thin.

Le mode de réalisation représenté sur la figure 2 comporte également un tube 10 solidaire de la boíte et comprenant une face cylindrique intérieure 10c, et une couronne 12. Cette dernière est munie, dans sa portion engagée dans le tube 10, d'une gorge 28 cylindrique s'étendant radialement vers l'extérieur et munie d'une surface cylindrique 28a concentrique à la face 10c. Dans cette gorge est disposé le joint d'étanchéité 22, dont les lèvres 22a et 22b sont respectivement en appui contre la face 10c et la surface 28a. Ici aussi, les lèvres définissent un logement 24 dans lequel est disposé un organe élastique 26.The embodiment shown in FIG. tube 10 secured to the box and comprising an inner cylindrical face 10c, and a crown 12. The latter is provided, in its engaged portion in the tube 10, a cylindrical groove 28 extending radially towards outside and provided with a cylindrical surface 28a concentric with the face 10c. In this groove is disposed the seal 22, whose lips 22a and 22b are respectively in abutment against the face 10c and the surface 28a. Right here also, the lips define a housing 24 in which is disposed a elastic member 26.

Comme dans le premier mode de réalisation, le logement 26 est ouvert vers l'extérieur de la boíte, de manière à ce que, si la montre est plongée dans l'eau, la pression de celle-ci tende à appliquer les lèvres contre les surfaces de contact du tube et de la couronne.As in the first embodiment, the housing 26 is open towards the outside of the box, so that if the watch is immersed in the water, the pressure of it tends to apply the lips against the surfaces contact of the tube and the crown.

Dans ce mode de réalisation, on évite le risque de déformation de la lèvre 22a lors de la mise en place de la couronne 12 sur le tube 10, du fait que la partie reliant les lèvres 22a et 22b est engagée dans le tube 10 avant les lèvres elles-même. Ces dernières peuvent alors glisser sans risque de s'enrouler. In this embodiment, the risk of deformation of the lip is avoided 22a during the introduction of the ring 12 on the tube 10, because the portion connecting the lips 22a and 22b is engaged in the tube 10 before the lips themselves. The latter can then slide without risk of wrap.

La figure 3 représente une commande à poussoir pour montre munie d'une garniture selon l'invention. Comme dans les modes de réalisation décrits précédemment, la boíte porte un tube 10 la traversant de part en part et définissant un axe A-A. Un poussoir 30 est disposé sur le tube 10. Il comporte une portion cylindrique 30a engagée dans le tube 10, une portion annulaire 30b entourant le tube 10, ces portions étant reliées entre elles par une portion 30c formant la surface d'appui permettant une commande par pression.FIG. 3 represents a push-button for a watch provided with a pad according to the invention. As in the embodiments described previously, the box carries a tube 10 passing through from one side to the other and defining an axis A-A. A pusher 30 is disposed on the tube 10. It comprises a cylindrical portion 30a engaged in the tube 10, an annular portion 30b surrounding the tube 10, these portions being interconnected by a portion 30c forming the support surface for pressure control.

Le tube 10 est muni, à son extrémité extérieure, d'une gorge 10d délimitée radialement par deux collerettes 10e et 10f et munie d'un fond plat. Un joint d'étanchéité 22 est disposé dans la gorge 10d, une lèvre 22a étant en appui contre la surface intérieure de la portion 30c, l'autre 22b contre la surface du fond de la gorge 10d, ces deux surfaces étant parallèles entre elles.The tube 10 is provided at its outer end with a delimited groove 10d radially by two flanges 10e and 10f and provided with a flat bottom. A seal sealing 22 is disposed in the groove 10d, a lip 22a being in abutment against the inner surface of the portion 30c, the other 22b against the surface of the bottom of the groove 10d, these two surfaces being parallel to each other.

Dans ce mode de réalisation également, les lèvres forment un logement 24 dans lequel est disposé un organe élastique 26. Le logement 24 est ouvert vers l'extérieur de la montre, de telle sorte que, si cette dernière est plongée dans l'eau, la pression qu'elle exerce tend à appliquer les lèvres contre leurs surfaces de contact.In this embodiment also, the lips form a housing 24 in which is disposed an elastic member 26. The housing 24 is open towards the outside of the watch, so that if the latter is diving in water, the pressure it exerts tends to apply the lips against their contact surfaces.

Les collerettes 10e et/ou 10f limitent l'espace dans lequel est disposé le joint 22, mais assurent en outre une fonction de butée, empêchant qu'une pression trop élevée sur le poussoir n'écrase l'organe élastique 26.The flanges 10e and / or 10f limit the space in which the gasket is arranged 22, but also provide a stop function, preventing a pressure too high on the pusher does not crush the elastic member 26.

Avec ce dernier mode de réalisation, une pression exercée sur le poussoir en immersion n'affectera pas l'étanchéité, puisque le joint est compressé.With this last embodiment, a pressure exerted on the pusher immersion will not affect the seal, since the seal is compressed.

Une telle solution est aussi applicable aux couronnes, et plus particulièrement aux couronnes vissées. Dans ce cas, un deuxième joint complètera avantageusement la garniture. Il pourrait être aussi bien du type représenté à la figure 1 qu'à la figure 2. Il est également envisageable d'utiliser un joint torique classique.Such a solution is also applicable to crowns, and more particularly screwed crowns. In this case, a second seal will complete advantageously the gasket. It could be of the type represented in Figure 1 that in Figure 2. It is also possible to use a seal classical ring.

Ainsi, grâce aux caractéristiques particulières que présentent les différents modes de réalisation décrits précédemment, il est possible de réaliser une boíte de montre de construction simple et présentant des caractéristiques d'étanchéité particulièrement intéressantes.Thus, thanks to the particular characteristics that the different embodiments described above, it is possible to perform a watch box of simple construction and having characteristics particularly interesting sealing.

On relèvera enfin que les trois modes de réalisation décrits peuvent être combinés entre eux sans pour autant sortir du cadre de l'invention. On peut aussi imaginer que ce type de garniture peut être sans autre appliqué à une montre disposant d'une couronne et/ou de poussoirs vissés.Finally, it will be noted that the three embodiments described can be combined without departing from the scope of the invention. We can also imagine that this type of trim can be without any other applied to a watch having a crown and / or screwed pushers.

Dans les exemples ci-dessus, les lèvres du joint sont en contact soit avec des surfaces cylindriques (figures 1 et 2) soit avec des surfaces planes (figure 3). Il serait également envisageable de faire travailler les lèvres sur des surfaces coniques, le joint étant toutefois obligatoirement tourné de manière à ce que le logement 24 soit ouvert vers l'extérieur de la montre.In the examples above, the lips of the seal are in contact with either cylindrical surfaces (Figures 1 and 2) or with flat surfaces (Figure 3). It would also be possible to work the lips on surfaces however, the seal must be rotated in such a way that the housing 24 is open towards the outside of the watch.

Il est bien clair que le joint 22 pourrait être en un autre matériau que le caoutchouc. Il doit, toutefois présenter une bonne souplesse, sans pour autant risquer de se déformer.It is quite clear that the seal 22 could be of a different material than the rubber. It must, however, have good flexibility, without as much risk of distortion.

L'organe élastique 26 pourrait être réaliser également sous la forme d'une bague découpée et pliée, comme décrit dans la demande de brevet W02004046831 au nom de la demanderesse.The elastic member 26 could be made also in the form of a ring cut and folded, as described in the patent application WO2004046831 in the name of the applicant.
