Embodiment Construction

[0020] refer to Figure 2A with 2B , the first embodiment of the timepiece movement according to the present invention will be described below. The horological movement 24 is provided with an analog display device for an analog display of the date, which periodically changes information and has a number of functions F1, F2, etc., which can be controlled by a watch provided with such a horological movement. users to choose. The analog display device comprises a ring 26 provided with a first ring gear 28 and a drive mechanism 30 . A number of dates "1" to "31" are printed on the ring 26 as well as the names of the number of possible functions. Each date and each function defines a discrete display position of the ring 26 through apertures provided in the dial mounted on the timepiece movement 24 . The actuation is periodic for days and intermittent for selecting a function from among possible functions.

[0021] The drive mechanism 30 is formed by a Maltese cross system def...

Abstract

The timepiece movement is provided with an analogue device for displaying information whose value varies periodically or intermittently, this analogue display device including, on the one hand, an indicator provided with a first toothing, and on the other hand, a mechanism for the periodic or intermittent driving of the indicator. The drive mechanism is formed by an irreversible transmission system which ensures a shock resistant function for the indicator. The display device further includes a positioning jumper for the indicator generating a positioning force on the first toothing, which is sufficient to precisely position the indicator in a plurality of discrete display positions, but considerably insufficient to ensure a shock resistant function for the indicator. Thus, the indicator can be driven with a relatively low torque; which therefore requires less energy and makes it possible to provide a drive mechanism with a lower gear reduction for the drive torque transmission ratio.

Description

technical field [0001] The invention relates to the field of timepiece movements comprising an analogue display of information whose value is periodically or between predetermined discrete values, in particular calendar information and / or functions / applications selected from a plurality of possible functions / applications Changes intermittently. "Value" generally refers to numbers, calendar information (such as date, week or month), and also a function or application selected from a number of functions or applications, although this list is not exhaustive. In particular the invention relates to drive mechanisms for simulating periodic or intermittent movement of an indicator, and shock resistant mechanisms for such indicators, plus the indicator at each of a plurality of said discrete display positions precise positioning. Background technique [0002] There are mainly three known mechanisms for driving calendar indicators, in particular date rings: continuous mechanisms, t...
