Assembly component comprising two series of elastic structures and timepiece incorporating this component |
摘要 |
<p>The element e.g. hour hand (18), has an opening (32) for axial insertion of a rod (26) and comprising an inner wall (33) with elastic structures (34) arranged in two rows (S1, S2). Each structure comprises a support surface (36) for radially locking the rod to fix the assembling element with respect to the rod. The rows (S1, S2) of the elastic structures are etched in a thin upper silicon layer (39) and a thick lower silicon layer (41) of a silicon on insulator type plate, respectively. The upper and lower layers are separated by an intermediate layer formed of silicon oxide.</p> |
