UHRMECHANISMUS, DER EINEN STERN UND EINE SPERRFEDER UMFASST

摘要

The watch mechanism comprises a star (17) and a jumper spring (31) comprising a rigid element (33) having a protrusion (35) arranged to cooperate with the star, and at least one elastic arm (37a, 37b) integral of the rigid element by one of its ends and arranged so as to at least partially surround the star (17), the jumper spring (31) being mounted on a support (15), and the device further comprising means for guide (39, 40, 41a, 42a, 41b, 42b) arranged so as to allow the rigid element (33) to move in translation parallel to a determined direction relative to the support when the rigid element is lifted by one of the teeth of the star and then it falls between two teeth thereof, the support (15) still having at least one stop (45, 46) arranged to constrain the jumper spring by retaining the distal ends of said at least one elastic arm (37a, 37b), so that that the rigid element (33) is biased against the star (17).
