Description

Montre munie d'un Organe de commande du mecanisme interieur Lobjet de la presente invention est une montre munie d'un örgane de commande du mecanisme int6rieur, traversant de faron 6tan- che une paroi de la holte et comprenant une tige portant une couronne de manoeuvre dont une partie fait joint avec la boite de montre. Cette montre est caract6ris6e par 1e fait qu'au moins cette partie de la couronne est en une matiere non m6tallique compressible et fait joint avec la boite sans interposition dune autre matiere. Watch fitted with a control member for the internal mechanism part of which is attached to the watch case. This watch is characterized by the fact that at least this part of the crown is made of a compressible non-metallic material and is attached to the case without the interposition of another material.

Le dessin ci-annexe represente, ä titre d'exemple, deux formes d'exdcution de 1'objet de la pr6sente invention, oü 1e m6canisme de commande est constitue par un remontoir muni dune couronne de commande. The attached drawing shows, by way of example, two forms of execution of the object of the present invention, where the control mechanism is constituted by a crown fitted with a control crown.

Les fig. 1 et 2 sont des coupes par Faxe de la tige de remontoir de la premiere, respec- tivement de la seconde forme d'exkution. Figs. 1 and 2 are cross-sections by Faxe of the winding stem of the first, respectively of the second form of execution.

En fig. 1, 1 represente la paroi de la boite de montre, munie du tube usuel 2. 3 est 1e corps de la couronne de remontoir solidaire de la tige de remontoir 6. Ce corps de cou- ronne 3 est en une matiere plastique synth6ti- que ; an utilisera avec avantage une matiere du type polyamide, teile, par exemple, que celle connue dans 1e commerce sous 1e nom de < nylon . 0n pourrait aussi employer des r6@ines vinyliques telles que 1e produit de mar- que plexiglas ou un polystyrol ou d'autres ma- tieres non m6talliques, compressibles, 61asti- ques et dtanches.- 4 est un revetement m6talli- que entourant les parties visibles du corps de la couronne, pour que cette derniere ne tran- che pas sur 1e reste de la boite. In fig. 1, 1 represents the wall of the watch case, fitted with the usual tube 2. 3 is the body of the winding crown secured to the winding stem 6. This crown body 3 is made of a synthetic plastic material ; year will advantageously use a material of the polyamide type, such as, for example, that known in the first trade under the first name of "nylon". Vinyl resins such as Plexiglas or polystyrol or other non-metallic, compressible, elastic and waterproof materials could also be employed. visible from the body of the crown, so that the latter does not stand out against the rest of the case.

La couronne pr6sente, sur sa face inte- rieure, une rainure circulaire 5 dans laquelle penetre 1e tube 2. Les dimensions de ces e16- ments sont calculees de fagon que Fune ou 1'autre des parois circulaires 5a et 5b de la rai- nure, ou les deux ä la fois, fassent joint sur la surface du tube avec laquelle .eile est en con- tact, et ceci saus interposition dune autre piece. The crown has, on its inside face, a circular groove 5 into which the tube 2 penetrates. The dimensions of these elements are calculated so that one or the other of the circular walls 5a and 5b of the groove , or both at the same time, make a joint on the surface of the tube with which it is in contact, and this without the interposition of another part.

Dans la forme d'ex6cution de la fig. 2, 7 est 1e corps de la couronne de remontoir entie- rement en la substance susmentionn6e et re- couvert extdrieurement par un revetement me- tallique 8 ; cette couronne presente un man chon 9 venu dune pike avec ce corps et en la meme substance, manchon qui p6netre dans un trou cylindrique 10 de laRTI ID="0001.0273" WI="8" HE="4" LX="1549" LY="1977"> boite de montre et fait joint avec la paroi de celui-ci sans inter- position dune autre pike. In the embodiment of FIG. 2, 7 is the body of the winding crown made entirely of the aforementioned substance and covered on the outside by a metal coating 8; this crown presents a sleeve 9 come from a pike with this body and in the same substance, sleeve which enters a cylindrical hole 10 of theRTI ID="0001.0273" WI="8" HE="4" LX="1549" LY ="1977"> watch case and joined with the wall thereof without the interposition of another pike.

Bien entendu, 1e manchon 9, toujours en la substance susmentionn6e, pourrait etre rap- port6 sur 1e corps de la couronne qui, lui, serait m6tallique. Of course, the first sleeve 9, still in the aforementioned substance, could be attached to the body of the crown which itself would be metallic.
