Title (EN) TIGHT WATCHCASE WITH REMOVEABLE FLAT POLYGONAL GLASS
(FR) BOITE DE MONTRE ETANCHE A VERRE POLYGONAL PLAT, AMOVIBLE
Abstract:
(EN) In the watchcase with flat removeable polygonal glass, the glass (1a) extends up to the edge of the case, except on two edges, where it is held between projecting parts (3) of the case. The glass is secured between the parts (3) by cylindrical pins (6) engaged into corresponding passages (7, 8) formed half within the case and half within the glass. The glass and the pins (6) are secured in place transversally by the pressure that the fittings (10, 11) exert on the glass. The rough walls of the passages (7, 8) and of the pins which are softer than the case and the glass, increase the blocking effect of the fittings (10, 11). A mask and the edge of the glass, extending up to the right angle inner face of the raising (14) masks the fitting (11). The sides of the glass secured to the case may also be curved.
(FR) Dans la boite de montre a verre polygonal plat amovible, le verre (1a) s"etend jusqu"au bord de la boite, sauf sur deux cotes, ou il est pris entre des parties saillantes (3) de la boite. Le verre est retenu entre les parties (3) par des goupilles cylindriques (6) engagees dans des passages correspondants (7, 8) formes par moitie dans la boite et par moitie dans le verre. Le verre et les goupilles (6) sont retenus en place transversalement par la pression que les garnitures (10, 11) exercent sur le verre. Des parois rugueuses des passages (7, 8) et des goupilles plus tendres que la boite et le verre augmentent l"effet de blocage des garnitures (10, 11). Un masque sous le bord du verre, s"etendant jusqu"au droit de la face interne du rehaut (14) cache la garniture (11). Les cotes du verre fixes a la boite peuvent aussi etre incurves.
