Description
Pièce d'horlogerie La présente invention a pour objet une pièce d'horlogerie.
Cette pièce d'horlogerie est caractérisée par le fait que, sur une partie de sa surface extérieure, est fixée une substance changeant de couleur lorsque le degré d'humidité de l'atmosphère varie.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de la pré sente invention.
La fig. 1 en est une vue en plan.
La fig. 2 en est une vue en coupe selon <I>I1-11</I> de la fig. 1.
La montre-bracelet 1 représentée com prend une carrure 2 et une lunette 3 présen tant une gouttière circulaire 4 dans laquelle est coulée une substance 5 changeant de couleur lorsque le degré d'humidité de l'atmosphère ambiante varie. Une telle substance peut être, par exemple, un gel de silice imprégné de chlo rure de cobalt qui présente une couleur bleue quand le degré d'humidité de l'atmosphère am biante est faible et une couleur rose lorsque le degré d'humidité de l'atmosphère ambiante est élevé.
La teneur en humidité de l'atmosphère va riant généralement, dans les régions tempé rées, en sens inverse de la pression atmosphé rique, un virage du bleu au rose de l'anneau de chlorure de cobalt 5 indiquera donc géné ralement une diminution de la pression atmo- sphérique avec probabilité de pluie prochaine et un virage du rose au bleu une élévation de la pression atmosphérique avec probabilité de beau temps.
Au lieu d'être coulée dans une gouttière de la lunette, la substance 5 pourrait encore être fixée au verre de montre, au bracelet ou à une partie quelconque de la boîte de la mon tre qui n'est pas au contact de la peau de l'usager, mais est exposée à l'atmosphère am biante.
Timepiece The present invention relates to a timepiece.
This timepiece is characterized by the fact that a part of its outer surface is fixed with a substance which changes color when the degree of humidity of the atmosphere varies.
The accompanying drawing represents, by way of example, an embodiment of the present invention.
Fig. 1 is a plan view.
Fig. 2 is a sectional view along <I> I1-11 </I> of FIG. 1.
The wristwatch 1 shown com takes a caseband 2 and a bezel 3 having a circular channel 4 into which is cast a substance 5 which changes color when the degree of humidity of the ambient atmosphere varies. Such a substance can be, for example, a silica gel impregnated with cobalt chloride which exhibits a blue color when the humidity of the ambient atmosphere is low and a pink color when the humidity of the ambient atmosphere is low. ambient atmosphere is high.
As the moisture content of the atmosphere in temperate regions generally goes in the opposite direction to atmospheric pressure, a change from blue to pink in the cobalt chloride ring 5 will therefore generally indicate a decrease in atmospheric pressure. atmospheric pressure with probability of rain in the near future and a turn from pink to blue an increase in atmospheric pressure with probability of good weather.
Instead of being poured into a gutter of the bezel, the substance 5 could still be attached to the watch glass, to the bracelet or to any part of the watch case which is not in contact with the skin of the watch. user, but is exposed to the ambient atmosphere.
