Abstract (en)
The collet has an inner flexible structure (10) that elastically clasps a balance shaft (4). An outer rigid structure (11) is connected to the flexible structure at different attachment points (12a-12c). A spiral spring (2) is attached with the rigid structure at an attachment point (3) that is fixed on the shaft while pressing a collet-spiral assembly. The collet is made up of silicon. An independent claim is also included for a balance-spiral assembly comprising a horological balance and a spiral-collet assembly.
Abstract (fr)
Une virole d'horlogerie (1) comprend une structure flexible (10) apte à serrer élastiquement l'arbre (4) d'un balancier et une structure de rigidification (11) extérieure à la structure flexible (10) et rattachée à cette dernière en au moins un point (12a, 12b, 12c). Un spiral (2) formé d'un seul tenant avec la virole (1) est rattaché à la structure de rigidification (11) en un point (3) qui reste sensiblement fixe lors du chassage de l'ensemble virole-spiral sur l'arbre (4). <IMAGE>
