Embodiment Construction

[0026] The present invention stems from the following general inventive idea: to provide a universal time running equation mechanism which, for the display of solar time, takes into account not only the difference between civil time and solar time, but also the relationship with The difference between the user's longitude location relative to the center of the time zone where the user is located, and any time difference between the civil time where the user is located and the official time at the center of the time zone.

[0027] Figure 4A , 4B and 4C show a first embodiment of a generalized time running equation mechanism according to the present invention.

[0028] Figure 5A , 5B and 5C show a second embodiment of the generalized time running equation mechanism according to the present invention.

Abstract

Universal running equation of time mechanism including a differential device outputting a running equation minute which indicates the difference between civil time and solar time, the running equation minute driving a true running equation minute which drives a true running equation hour, a jumper spring cooperating with a star wheel connected to an arbour carrying a true running equation hour hand, a time zone wheel carrying the true running equation hour hand, a train making it possible to apply, to the true running equation hour, the time difference associated with the longitude position of a user, the time zone wheel making it possible to apply, to the arbour carrying the true running equation hour hand the difference between the true running equation hour and the civil hour at the place where the user is located.

Description

technical field [0001] The present invention relates to a universal running equation of time mechanism. More specifically, the present invention relates to an equation-of-time mechanism that accurately indicates that the sun is at its highest point ( i.e., zenith) time. Background technique [0002] In the same time zone, the sun is at its highest point at different times depending on whether one is located at the far east, center or west of that time zone. Between the two extreme positions, there is a time difference of 59 minutes. [0003] Also, the time in the country where the user is located may not coincide with the official time zone. This is the case, for example, in Switzerland, which, although located in the Greenwich Mean Time zone, has a time difference of one hour from the official time zone. [0004] Other countries have only one official time, but their territories cover multiple time zones. [0005] Finally, some countries change the time according to th...
