  • Publication number: 20240085853
    Abstract: A mechanism for actuating a flexible display hand including a first drive pipe and a second drive pipe connected to a first end of a second flexible arm, the first and second flexible arms being connected to one another by a tip at their second end, the first pipe being mounted at a defined first prestressing angle, and the second pipe being mounted at a defined second prestressing angle in the opposite direction to that of the first pipe, so that the elastically prestressed flexible display hand constantly maintains the entire actuating mechanism under tension during normal operation of the actuating mechanism, the actuating mechanism including a first cannon-pinion onto which the first drive pipe of the flexible display hand is driven.

  • Publication number: 20230418227
    Abstract: An actuation mechanism (60) of a flexible hand (44) to which a clockwork movement applies a first angular rotation (?1), 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 (?1) applied by the clockwork movement to the actuation mechanism (60) being modulated by an angle of rotation (?) by the actuation mechanism (60).

  • Publication number: 20230408980
    Abstract: A date display device (10) including: a dial (11) including date indications in the form of a character scale (15), of which a part is of apertures (150), a mobile index (12) with respect to the dial (11); a date mechanism configured to move the index (12) by one step per day, such that each position occupied by the index (12) denotes one of the characters (15); and a mobile element (13) arranged between the dial (11) and the date mechanism having on a surface facing the dial, a portion of interest (131), the mobile element being linked with the date mechanism such that the latter drives it in an active position, wherein the portion of interest is visible through the aperture (150) and in a rest position wherein the portion of interest is set back from the aperture and wherein a marking zone (160) is visible through the aperture.

  • Publication number: 20230367265
    Abstract: A flexible hand actuation mechanism to which a disk of a horological movement applies a first angular rotation (?1), the flexible hand including a first cannon and a second cannon connected to a point of the flexible hand via flexible arms, an operating position where the first cannon and the second cannon are coaxial about an exit axis, the first cannon being fitted with a first defined prestress angle, the second cannon being fitted with a second defined prestress angle of opposite direction to that of the first cannon, the actuation mechanism being arranged to actuate the flexible hand such that the latter changes shape and length in the desired manner by varying the angular position of the second cannon with respect to the first cannon by pivoting about the exit axis.
