Abstract (en)
The part has an opening (2) alternatively forming zones (8) for rigidification and positioning elastic deformation zones (10). The zones (10) are formed by a tab (12) of the part. The tab is formed of recesses (13, 15) opening into the opening and delimiting the tab whose end (14) extends above a theoretical contour of a cylindrical shaft (5) and provides a locking function when the shaft is placed. The part is made of a frangible material that is chosen among glass, silicon and quartz.
Abstract (fr)
La pièce est réalisée à partir d'une plaque (1) en un matériau cassant, tel que le verre, le quartz ou le silicium et comporte au moins une ouverture (2,4,6) pour le chassage d'un axe (3,5). Cette ouverture comporte alternativement des zones (8) de rigidification et de positionnement et des zones (10) à déformation élastique. Application à la fixation d'un axe sur des mobiles d'un mouvement horloger.
