Description
<B>Montre étanche</B> L'objet de la présente invention est une montre étanche dont au moins une pièce de la boîte présente au moins un trou par lequel passe un organe de commande du mécanisme de la montre. Cette dernière est caractérisée par le fait que cette pièce est en une matière synthétique du type polyamide, l'étanchéité entre l'organe de commande et la paroi de son trou étant obtenue par contact direct de ces parties sans interposition, entre elles, d'un pa quetage.
Le dessin ci-annexé représente, à titre d'exemple, une forme d'exécution de l'objet de la présente invention ; l'unique figure du des sin est une coupe axiale partielle de cette forme d'exécution.
La montre représentée comprend un fond- calotte 1 en une matière synthétique du type polyamide, par exemple en nylon, et recouvert extérieurement d'une couche métallique 2. 3 est la carrure et 4 la glace serrée entre un épaulement 5 du fond-calotte et une bague 6. 7 est le mouvement.
Le fond-calotte est percé d'un trou cylin drique 8 dans lequel est engagée la tige de re montoir 9 fixée dans le canon 10 de la cou ronne 11, l'étanchéité entre ce canon et la pa- roi du trou étant obtenue par contact direct de ces parties, sans interposition entre elles d'un paquetage quelconque. La couronne et son ca non pourront être en métal ou en matière plas tique, par exemple en une polyamide.
<B> Waterproof watch </B> The object of the present invention is a waterproof watch in which at least one part of the case has at least one hole through which passes a control member of the watch mechanism. The latter is characterized by the fact that this part is made of a synthetic material of the polyamide type, the sealing between the control member and the wall of its hole being obtained by direct contact of these parts without the interposition, between them, of a package.
The accompanying drawing represents, by way of example, an embodiment of the object of the present invention; the only figure of the sin is a partial axial section of this embodiment.
The watch shown comprises a bottom-cap 1 made of a synthetic material of the polyamide type, for example nylon, and covered on the outside with a metal layer 2. 3 is the middle part and 4 is the crystal clamped between a shoulder 5 of the bottom-cap and a ring 6. 7 is the movement.
The bottom-cap is pierced with a cylindrical hole 8 in which is engaged the mounting rod 9 fixed in the barrel 10 of the crown 11, the seal between this barrel and the wall of the hole being obtained by direct contact of these parts, without interposition between them of any package. The crown and its ca non may be made of metal or of a plastic material, for example of a polyamide.
