Abstract: A variable timepiece display mechanism includes a resilient hand with a drive pipe integral with a single-piece flexible strip including flexible segments joined at tips, a first segment thereof extends between the first pipe and a first tip. The mechanism also includes a driver for driving the pivoting of the pipe, and a stressor for stressing the first flexible segment in order to vary the position of the first tip relative to the output axis, as a function of the forces applied to the flexible strip. The drier and/or the stressor includes a first shaped gear train and/or a second shaped gear train in order to accelerate, stabilize the speed of, or slow at least the pipe over a part of the angular travel thereof.

Abstract: The present invention proposes a timepiece mechanism comprising: a lever, rotatable about a lever axis, the angular position of the lever representing a first value, wherein a zero value of the first value corresponds to a reference direction, a sliding block mounted to move in translation on the lever in a direction substantially perpendicular to the axis of the lever and comprising a guide-mark element whose trajectory in translation relative to the lever is secant to the lever axis, the radial position of the guide-mark element with respect to the lever axis representing a second value, an output device formed of a deformable parallelogram in a plane perpendicular to the lever axis, the parallelogram including a first side, which is stationary with reference to the lever axis and perpendicular to the reference direction, a second side, which is opposite to the first side and linked in translation to the guide-mark element in the direction perpendicular to the reference direction, the angular position of the third and fourth sides of the parallelogram, which are adjacent to the first side, being substantially proportional to the product of the first and second values.

Abstract: Timepiece movement including a date display drive device formed of a display disc including a toothing, said drive device including driving means and a drive source. The driving means includes a wheel set including pins, having a toothed wheel and a pinion including pins, and an engaging wheel engaging said toothed wheel. The pinion with pins includes a pair of pins configured to be positioned on either side of any tooth of the toothing. The toothed wheel of the pin wheel and the engaging wheel respectively have complementary non-circular profiles. When the two pins are oriented in a tangential direction to the toothing, these two wheels have a first gear ratio that is lower than a second gear ratio between them when the two pins are in perpendicular alignment to said tangential direction.

Abstract: A horological display mechanism with an elastic hand (1) for driving, about a shaft (D), pipes mounted at the ends of a flexible blade (3), arranged to deform the flexible blade (3), including a mechanism acting on the drive train of the first pipe (2) and of the second pipe (4) and which includes two planetary wheels (82; 84) for driving the pipes (2; 4), and an input planet-carrier chassis (180) for driving the hand (1), and rotatable with a regulation cam (801), the track (802) of which includes a rising edge and falling edge. An elastic arm (803) has a distal end which cooperates with the track and a rising edge of which raises the elastic arm (803) away from the axis of the cam to consume torque, and a falling edge which makes the elastic arm move back towards the axis to restore torque to the system.
