Description
Glace en verre organique pour pièce d'horlogerie et procédé pour sa fabrication La présente invention a pour objet une glace en verre organique pour pièce d'horlo gerie et un procédé pour sa fabrication.
La glace est caractérisée par le fait qu'elle porte, sur sa. face intérieure, des appliques métalliques incrustées.
Le procédé de fabrication est caractérisé par le fait qu'on incruste, lors du moulage, des appliques métalliques dans la face inté rieure de la glace.
Le dessin annexé représente, à titre d "exemple, une forme d'exécution de l'objet de l'invention.
La fig.1 est une vue en plan d'une glace pour pièce d'horlogerie, et la fig.2 est une coupe, à échelle agTan- die, suivant la ligne II-II de la fig.1.
La glace représentée, en verre organique, est désignée par 1. Elle présente, sur sa face intérieure 2, des appliques en métal 3 cons tituant des signes horaires. Ces signes ho- raires sont réunis par deux cercles concen triques 4 et 5 formant ainsi un tour d'heures d'une seule pièce noyé dans l'épaisseur de la glace.
Ce tour .d'heures est incrusté dans la glace loirs du moulage de celle-ci. Les appliques métalliques pourraient ne pas constituer des signes horaires, mais être simplement décoratives.
An organic glass crystal for a timepiece and method for its manufacture The present invention relates to an organic glass crystal for a timepiece and a method for its manufacture.
Ice cream is characterized by the fact that it wears on its. interior face, inlaid metal appliques.
The manufacturing process is characterized by the fact that, during molding, metallic appliques are embedded in the inner face of the crystal.
The appended drawing represents, by way of example, an embodiment of the object of the invention.
Fig. 1 is a plan view of a glass for a timepiece, and fig. 2 is a section, on an enlarged scale, along line II-II of fig.1.
The mirror shown, made of organic glass, is designated by 1. It has, on its inner face 2, metal appliques 3 constituting hour signs. These hour signs are united by two concen tric circles 4 and 5 thus forming a single-piece hour circle embedded in the thickness of the ice.
This tower. Of hours is encrusted in the dormouse mirror of the molding thereof. Metallic appliques might not be hour signs, but just decorative.
