Title:
DEVICE FOR LOCKING AND SEALING IN PARTICULAR FOR A DIVER'S WATCH
Document Type and Number:
WIPO Patent Application WO2003107097
Kind Code:
A3
Abstract:
The invention concerns a novel sealing system assembly through the crown mainly characterized in that it is based on the displacement of the mobile collet (4) integral with the winding stem (1) and the crown (7). The rotation of the nut (5) moves the crown (7) and the collet (4) and enables the crown (7) to be pulled, thereby enabling all the functions mentioned by the manufacturer. The sealing is provided by three O-rings and a flat lock-joint. Two O-rings are placed on the cylindrical mobile part of the collet (4). The third is positioned on the flat portion of the collet (4) and assembled with the crown (7). The flat lock-joint (6) in the seat of the crown (7) ensures sealing conditions against water all infiltration through the crown (7). The crown (7) is locked against the middle. The user can use two positions. The locked position of the device protects the assembly against accidental pulling of the crown (7) and the unlocked position enables implementation of the functions associated with the winding stem (1).
