    • A timepiece movement is disclosed which may comprise a going train, and a mechanism having a first cinematic connection with the going train and arranged to drive an indicator member in a stealthy rotational movement, the latter being activated periodically with a predefined period. The mechanism may also comprise a first wheel-and-pinion unit comprising a first wheel at least indirectly in engagement with the going train, a second wheel-and-pinion unit, mounted coaxially with the first wheel-and-pinion unit and, having at least one stop region and a second wheel, these being integral in rotation. A second cinematic connection connects the second wheel to the indicator member, an elastic member connecting the first wheel-and-pinion unit to the second wheel-and-pinion unit in such a way that its degree of tension is a function of respective angular positions of the first and second wheel-and-pinion units. The mechanism may further comprise locking means designed to prevent the second wheel-and-pinion unit from rotating between two successive movements of the indicator member, as well as release means designed to act on the locking means, in each period, in order to release them momentarily and permit stealthy rotation of the second wheel-and-pinion unit through a predefined angle The mechanism may also comprise a retarding device acting on the second wheel-and-pinion unit in such a way as to limit its speed of stealthy rotation.
    • 公开了一种钟表运动,其可以包括行进列车,以及具有与行驶列车的第一电影连接并被布置成以隐形旋转运动驱动指示器部件的机构,后者以预定义的周期周期性地被激活。 该机构还可以包括第一轮和小齿轮单元,其包括至少间接地与前进列车接合的第一轮,与第一轮 - 小齿轮单元同轴安装的第二轮 - 小齿轮单元,并且具有 至少一个止动区域和第二车轮,它们在旋转中是一体的。 第二电影连接将第二轮连接到指示器构件,弹性构件将第一轮 - 小齿轮单元连接到第二轮 - 小齿轮单元,使得其张力是相应角位置的函数 的第一和第二轮 - 小齿轮单元。 该机构还可以包括设计成防止第二轮和小齿轮单元在指示器构件的两次连续移动之间旋转的锁定装置,以及设计成在每个周期中作用在锁定装置上的释放装置,以便释放 它们暂时地允许第二轮 - 小齿轮单元通过预定角度进行隐形旋转。该机构还可以包括以限制其隐形旋转速度的方式作用在第二轮 - 小齿轮单元上的延迟装置。
