摘要： 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.

摘要： The invention relates to a setting mechanism for a timepiece movement, including a setting gear train, a winder rod adapted to be moved from a first axial position termed a running position to a second axial position termed a setting position, a sliding pinion adapted to be moved from a first axial position in which the sliding pinion is disengaged from the setting gear train to a second axial position in which the sliding pinion meshes with the setting gear train, and a lever interengaged with the sliding pinion and adapted to pivot, when the winding rod is moved from a running position to a setting position and vice versa, in order to move the sliding pinion from the first axial position to the second and vice versa. The setting mechanism further includes, according to the invention, a device for immobilizing the setting gear train. This immobilizing device includes first and second immobilizing arms and an immobilizing wheel interengaged with the setting gear train. The first and second immobilizing arms are adapted, on the one hand, to the interengaged with the immobilizing wheel in a configuration termed locked in which the setting gear train is immobilized and, on the other hand, to be disengaged from the immobilizing wheel in a configuration termed unlocked in which the sliding pinion is free from meshing with the setting gear train. The immobilizing device includes to this end a locking/unlocking lever interengaged with the sliding pinion and adapted to cooperate with the first and second immobilizing arms in order to pass from the locked configuration to the unlocked configuration and vice versa when the winding rod is moved from a running position to a setting position and vice versa.

摘要： A variable timepiece display mechanism includes a resilient hand with two drive pipes integral with a one-piece flexible strip includes a tip or an index, with a driver for driving the pivoting of the pipe, and a stressor for stressing the strip so as to vary the position of the tip relative to the axis of the pipes, which includes an accelerator or decelerator device arranged such that it accelerates, or stabilizes the speed of, or slows down the first pipe and/or the second pipe over at least part of the angular travel thereof, which includes a device with a first differential gear on the drive gear train of the first pipe and/or a second differential gear on the drive gear train of the second pipe, and at least one cam forming an input of a differential gear.
