Lug and gongs assembly for minute repeater in wrist watch, has gongs extending from lug in plane toward zone, where gongs change trajectory such that radius of one of gongs and plane of other gong are changed to avoid meeting of gongs

摘要

The assembly has a lug (1) and two gongs (3, 5) extending from the lug in two opposed directions along circle arcs including respective radii (I, E). The gongs extend from the lug in a same plane towards a zone (Z4), where the gongs change trajectory such that radius of one of the gongs changes and plane of the other gong are changed to avoid meeting of the gongs. The lug is carried out in a single part with the gongs. Junction points between the gongs and the lug are symmetrical relative to a plane (8) perpendicular to the same plane. An independent claim is also included for a striking mechanism.
