Abstract (en)

[origin: US2023418227A1] An actuation mechanism (60) of a flexible hand (44) to which a clockwork movement applies a first angular rotation (θ1), the flexible hand (44) including a first drive barrel (46) and a second drive barrel (50) connected to a tip (54) of the flexible hand (44) by a first and a second flexible arm (48), the first drive barrel (46) being provided with a first toothing (56) and the second drive barrel (50) being provided with a second toothing (58), the first and second drive barrels (46, 50) being mounted so the first toothing (56) of the first drive barrel (46) engages with the second toothing (58) of the second drive barrel (50) in the stressed position of the flexible hand (44), the angular rotation (θ1) applied by the clockwork movement to the actuation mechanism (60) being modulated by an angle of rotation (φ) by the actuation mechanism (60).
