Description
Remontoir étanche pour pièce d'horlogerie. La présente invention a pour objet un re montoir étanche pour pièce d'horlogerie, dont la couronne présente une creusure centrale taraudée permettant de la visser sur le pen dant. Ce remontoir est caractérisé par le fait qu'il comprend deux garnitures de joint, l'une logée dans le pendant et agissant radialement, sur le noyau de la couronne, dans toutes les positions axiales de cette dernière, l'autre dis posée dans le fond de la creusure de la cou ronne et s'appliquant contre la tranche du pendant lorsque la couronne est vissée sur celui-ci.
Le dessin annexé représente, à titre d'exem ple, une forme d'exécution de l'objet de l'in rention.
La figure est une coupe axiale d'un remon toir de montre.
Le corps de boîte est désigné par 1. Il porte un pendant 2 traversé par un canon 3 destiné à se tisser sur la tige de remontoir non représentée. La couronne du remontoir 4 porte un manchon 5 entourant le canon 3, et présente une creusure centrale 6 dont la paroi latérale est tauraudée pour se visser sur le pendant. Un ressort 7 prend appui, d'une part, sur la couronne 4, d'autre part, sur un épaulemént 3a du canon 3, et tend. à main tenir la couronne éloignée du pendant lors qu'elle n'est pas vissée sur lui, accouplant alors la couronne au canon 3 en amenant une partie 5a., d'alésage hexagonal, du manchon 5, en prise avec une partie 3b, à six pans, du canon 3.
L'étanchéité est assurée par deux garni tures de joint dont l'une, désignée par 8, par tiellement logée dans une gorge annulaire in térieure 9 du pendant, agit radialement sur le manchon 5, quelle que soit la position axiale de la couronne, et dont l'autre, désignée par 10 est logée dans le fond de la creusure 6 de la couronne. Cette garniture 10 est pressée sur la tranche du pendant 2 lorsque la couronne 4 est vissée sur celui-ci.
Waterproof winder for timepiece. The object of the present invention is a waterproof re-mount for a timepiece, the crown of which has a threaded central recess enabling it to be screwed onto the pendant. This winder is characterized by the fact that it comprises two gasket linings, one housed in the pendant and acting radially, on the core of the crown, in all the axial positions of the latter, the other placed in the crown. bottom of the recess of the crown and applying against the edge of the pendant when the crown is screwed onto it.
The appended drawing represents, by way of example, one embodiment of the subject of the invention.
The figure is an axial section of a watch winder.
The case body is designated by 1. It carries a pendant 2 crossed by a barrel 3 intended to be woven on the winding stem, not shown. The crown of the winder 4 carries a sleeve 5 surrounding the barrel 3, and has a central recess 6, the side wall of which is tauraudée to be screwed onto the pendant. A spring 7 is supported, on the one hand, on the crown 4, on the other hand, on a shoulder 3a of the barrel 3, and tends. by hand, hold the crown away from the pendant when it is not screwed onto it, then coupling the crown to the barrel 3 by bringing a part 5a., of hexagonal bore, of the sleeve 5, into engagement with a part 3b, hexagon, barrel 3.
Tightness is ensured by two gasket linings, one of which, designated by 8, partially housed in an internal annular groove 9 of the pendant, acts radially on the sleeve 5, whatever the axial position of the crown, and the other of which, designated by 10, is housed in the bottom of the recess 6 of the crown. This lining 10 is pressed onto the edge of the pendant 2 when the crown 4 is screwed onto the latter.
