Description

Montr e-etanclie. hans les montres etanches, an a dejä pro- pose d'empecher la Penetration de 1'humidite par 1e Pendant par un ajustement Parfait de la tige de remontoir ä 1'interieur dudit Pen dant. Lorsque cependant la montre est tres petite, les conditions d'ajustement deviennent < lesavantageuses. Les diametres sont trop pe- tits. 0n fatigue la tige en remontant la mon- tre. Les pieces ont la tendance ä prendre de l'ebat, sartout quand elles s'appuyent elasti- quement l'une sur 1'autre, et 1'Mancheite de- vient illusoire. Shows e-tanclie. In water-resistant watches, it has already been proposed to prevent the Penetration of moisture through the Pendant by a perfect fit of the winding stem inside said Pendant. When, however, the watch is very small, the adjustment conditions become less advantageous. The diameters are too small. You tire the stem when winding the watch. The pieces tend to spring up, especially when they rest elastically on each other, and the tightness becomes illusory.

Lobjet de 1'invention est une montre Manche Jans laquelle 1'Mancheite du Pendant est obtenue par ajustement exact de pieces glissant l'une sur 1'autre et qui est caraeterise en ce qu'il comporte un tube solidaire de la eouronne et dann lequel est conduit ä frotte- merit gras un tube solidaire de la carrure de la boite. De preference, la couronne compor- l:era ä. 1'interieur dudit tube une moitie d'ac- couplement cooperant avec une autre moitie se trouvant sur la tige de remontoir pour re- lier Bette derniere ä la couronne. Le dessin annexe represente, ä eitre d'exemple, quelques formes d'execution d'un Pendant selon 1'invention. The object of the invention is a Manche Jans watch in which the Mancheite of the Pendant is obtained by exact adjustment of parts sliding one over the other and which is characterized in that it comprises a tube integral with the crown and in which is led to greasy rubbing a tube secured to the middle of the case. Preferably, the crown comprises l: era ä. inside said tube a coupling half cooperating with another half located on the winding stem to connect the last Bette to the crown. The appended drawing shows, by way of example, some embodiments of a Pendant according to the invention.

La fig. 1 en est une elevation partielle- ment en coupe selon un plan Passant par Page de la tige de remontoir; La fig. 2 est une vue en bout de la tige solidaire du mouvement; La fig. 3 est une vue analogue ä la fig. 1, la couronne kant decouplee de la tige; La fig. 4 montre en elevation la conforma- tion d'un dMail et la fig. 5 ce dkail vu en bout; La fig. 5 est une forme d'execution pos- sible du bout de la tige de remontoir dejä montree en fig. 2. fig. 1 is an elevation partially in section along a plane Passing through Page of the winding stem; fig. 2 is an end view of the stem integral with the movement; fig. 3 is a view similar to FIG. 1, the kant crown decoupled from the stem; fig. 4 shows in elevation the conformation of a dMail and fig. 5 this dkail seen from the end; fig. 5 is a possible embodiment of the end of the winding stem already shown in FIG. 2.

En se referant aux fig. 1, 2 et 3, a designe la couronne dans laquelle est introduit ä force un tube b en mkal durci, de 1'acier trempe par exemple. L'interieur de ce tube est exactement rode pour glisser saus ebat quelconque sur un second tube c solidaire de la carrure d. Dans la couronne est visAe en e la moitie superieure f d'un accouplement. Celle-ei a deux branches elastiques semi-cylindriques. Elle est creuse et fendue en g sur toute sa longueur, de maniere ä pouvoir faire ressort, afin de faciliter 1'introduction dans une echancrure h quelle comporte, dune cheville z Plantee transversalement dans 1e bout 7g de la tige de remontoir solidaire dif mouvement et formant la seconde moitie de 1'accouple- ment. <B>11</B> est clair que la Pression exercee par les branches elastiques du bout superieur de la tige de remontoir sur la cheville i est telle que lorsqu'on tire sur la couronne pour ac- tionner 1e mecanisme de mise ä 1'heure, 1'ac- couplement des deux piäces reste Parfait. Referring to Figs. 1, 2 and 3, a denotes the crown into which is forced a tube b made of hardened mkal, hardened steel for example. The inside of this tube is exactly rode to slide without any movement on a second tube c attached to the middle part d. In the crown is screwed in e the upper half f of a coupling. This one has two semi-cylindrical elastic branches. It is hollow and split in g along its entire length, so as to be able to act as a spring, in order to facilitate insertion into a notch in which it comprises, a pin z Planted transversely in the end 7g of the winding stem integral with the movement and forming the second half of the coupling. <B>11</B> it is clear that the pressure exerted by the elastic branches of the upper end of the winding stem on pin i is such that when the crown is pulled to activate the setting mechanism time, the coupling of the two parts remains perfect.

Le fait de faire glisser un tube solidaire de la couronne sur un autre tobe solidaire du Pendant et contenant ä son tour la tige de remontoir permet de travailler avec des dia- mAtres suffisamment grands pour permettre un ajustage superficiel offrant toute garantie d'etancheite. Il est en effet impossible, meme par capillarite, qu'une goutte d'eau, si petite quelle soit, traverse la surface de contact existant entre les tubes b et e. The fact of sliding a tube attached to the crown on another tube attached to the Pendant and containing in turn the winding stem makes it possible to work with diameters large enough to allow a superficial adjustment offering any guarantee of water resistance. It is in fact impossible, even by capillarity, for a drop of water, however small, to cross the contact surface existing between the tubes b and e.

La construction decrite a en outre pour avantage de mehre la tige de remontoir en dehors de toute fatigue resultant dune force inegalement appliquee sur la couronne lors du remontage. Cette fatigue est entierement supportee par des Parties qui peuvent etre di- mensionn6es suffisamment pour les suppor- ter. Il n'existe en effet pas de limite absolue aux dimensions desdits tubes dont le diametre pourrait etre ä peu de Chose pres egal au dia- metre exterieur de la couronne. The construction described also has the advantage of protecting the winding stem from any fatigue resulting from uneven force applied to the crown during winding. This fatigue is entirely supported by Parts which can be dimensioned sufficiently to support them. There is in fact no absolute limit to the dimensions of said tubes, the diameter of which could be more or less equal to the outer diameter of the crown.

Dans la forme d'execution montree en fig. 4, 1e tube exterieur b est fendu et fait ressort. Il est bande de maniere ä enserrer parfaitement le tube c. Dans ce cas, le ro- dage peut etre un peu moins exact que lors- que ce tube b n'a pas de solution de conti- nuite. La fente peut etre remplie d'un mastie elastique qui augmente encore 1'etaucheite. In the embodiment shown in FIG. 4, the outer tube b is split and springs. It is wrapped in such a way as to enclose the tube perfectly c. In this case, running-in may be a little less exact than when this tube b has no continuity solution. The slot can be filled with an elastic putty which further increases the seal.

Au lieu de traverser la Partie de la tige de remontoir dune cheville servant ä 1'accou- plement des deux Parties, an pourrait, comme il est montre ä la fig. 5, fraiser 1'extremite de ladite tige pour y ereer un bourrelet trans- versal Z dopt 1'introduction ä 1'interieur des branches faisant ressort de la moitie d'accou- plement solidaire de la couronne n'offrirait pas davantage de difficultes que celui de la cheville, decrit en regard de la fig. `?. Instead of crossing the Part of the winding stem with a pin serving to couple the two Parts, one could, as shown in fig. 5, milling the extremity of the said rod to create therein a transverse bead Z dopt the introduction inside the branches springing from the coupling half integral with the crown would not offer any more difficulties than that of the ankle, described opposite fig. `?.
