Description
Pièce d'horlogerie L'objet de la présente invention est une pièce d'horlogerie, caractérisée par le fait que son dispositif ,indicateur de l'heure est protégé par deux glaces superposées situées à distance l'une de l'autre et constituées chacune par du verre artificiel.
Le dessin ci-annexé représente, à titre d'exemple, une forme d'exécution de l'objet de la présente invention et une variante.
La fig. 1 du, dessin est une coupe axiale, partielle, de cette forme d'exécution ; la fig. 2 est une coupe semblable de la variante.
En fig. 1, 1 est la lunette d'une boîte de montre et 2 son rehaut. Sur celui-ci repose, par l'intermédiaire d'un paquetage compressi- blé 3, une glace 4 en verre artificiel, par exem ple le produit marque Plexiglas . Elle est maintenue en place par le rebord 5 d'une se conde glace 6 située au-dessus d'elle et à dis tance et constituée aussi par du verre .artificiel. Ce rebord est chassé dans la lunette et main tenu appliqué contre un épaulement 7 de celle- ci par le moyen de la bague élastique 8.
Dans la variante de la fig. 2, on a introduit entre les deux glaces un .anneau <B>10</B> en une ma tière capable d'absorber l'humidité, par exem ple un gel desséché de silice (Si02) ;
cet anneau pourra absorber quelques traces d'humidité s'il en existe dans l'espace entre les deux glaces. On pourrait le Templacer par un anneau en une matière changeant de couleur sous l'in fluence de l'humidité, par exemple un sel de cobalt, plus. particulièrement le chlorure de cobalt qui, sous l'influence de l'humidité, passe du bleu au rose.;
de cette façon, le porteur de la montre sera averti si la glace cessait d'être étanche.
A la place du joint plastique 3, on pourrait utiliser un ciment imperméable à l'eau et sou dant le bord de la glace à la boite.
Timepiece The object of the present invention is a timepiece, characterized by the fact that its device, the time indicator, is protected by two superimposed glasses located at a distance from each other and each made up of by artificial glass.
The accompanying drawing represents, by way of example, an embodiment of the object of the present invention and a variant.
Fig. 1 of the drawing is an axial section, partial, of this embodiment; fig. 2 is a similar section of the variant.
In fig. 1, 1 is the bezel of a watch case and 2 is its flange. On this rests, by means of a compressible package 3, a mirror 4 made of artificial glass, for example the product brand Plexiglas. It is held in place by the rim 5 of a second ice conde 6 located above it and at a distance and also consisting of .artificial glass. This rim is driven into the bezel and hand held pressed against a shoulder 7 thereof by means of the elastic ring 8.
In the variant of FIG. 2, a <B> 10 </B> ring made of a material capable of absorbing humidity, for example a dried silica gel (Si02), was introduced between the two glasses;
this ring will be able to absorb some traces of humidity if there is any in the space between the two glasses. It could be replaced by a ring made of a material which changes color under the influence of humidity, for example a cobalt salt, plus. especially cobalt chloride which, under the influence of humidity, changes from blue to pink .;
in this way, the wearer of the watch will be warned if the ice ceases to be waterproof.
Instead of the plastic seal 3, we could use a waterproof cement that welds the edge of the glass to the box.
