  • Patent number: 8902717
    Abstract: A clock assembly containing a specialized clockwork. The clockwork contains a hub of three concentric posts upon which are mounted the second hand, minute hand, and hour hand of the clock. The post that connects to the second hand is the widest and shortest post on the hub. Consequently, when a second hand is connected to this outer-most post, the second hand can rotate under the minute hand and the hour hand closest to the clock face. By positioning the second hand post on the exterior of the hub, a 1:1 ratio can be maintained between the rotations of the clock motor and the rotations of the second hand post. This enables the full power of the motor to be transferred to the second hand post. Accordingly, the clockwork is capable of move, large, heavy, and unbalanced second hands.

The base may comprise a support element bearing the arm. The base may further comprise two link elements each linking an end of the support element to a fixed element of the base. The jumper may be associated with a control member arranged in such a way that an axial rotation of the control member provokes a displacement of the support element by deformation of a frame, of which the support element and the two link elements form sides.

  • Patent number: 8614931
    Abstract: Timepiece movement including a module fitted with a first wheel set meshing with a second wheel set, which pivots on a base on which the module is mounted. The movement includes a means of positioning the module formed by a cam, at least most of the periphery of which forms an Archimedes' spiral. The cam is arranged so as to allow the distance of centers between the first and second wheel sets to be adjusted, when the cam is rotated on itself about the center of the Archimedes' spiral. The cam is preferably calibrated. The invention also concerns a method of adjusting the distance of centers between the two wheel sets using said cam to optimise the gearing efficiency of the two wheel sets.

    Abstract: Clockwork movement for a wristwatch, comprising a kinematic chain including at least one belt (20, 21) for transmitting the movements and/or couples between at least two pulleys. The pulleys are held on the bottom plate or the bridges by ball bearings (151, 161, 171, 181). The movement is rewound by means of linear oscillating mass (14) charging four barrels (15, 16, 17, 18) through a couple distributor (40). The barrels are non-parallel to one another. The back cover is covered by inclined glasses (110, 120, 130) allowing the barrels, the linear oscillating mass and at least certain pulleys to be seen. The regulating organ (51) is removable.

  • Patent number: 8189431
    Abstract: A piezoelectric drive device includes a piezoelectric actuator and a rotation transfer device. The piezoelectric actuator includes a vibrator and a rotor that is rotated in one specific direction by the vibrator. The rotation transfer device transmits rotational energy from the rotor to a driven rotating body, and includes an elastic device that stores rotational energy and a rotation limiting device having a drive wheel and a driven wheel. The rotation transfer device allows the driven wheel to rotate a specific angle, and restricts driving the drive wheel. The elastic device and the rotation limiting device are disposed so that rotational energy transmitted from the rotor is transmitted through one to the other of the elastic device and the rotation limiting device. The rotor, the elastic device, and the rotation limiting device render a serial path for transmitting rotational energy.
