Optimised striking mechanism disc-vibration plate for a timepiece

摘要

A disc-vibration plate assembly for a musical or striking timepiece, including at least one disc rotating about an axis and provided with pins projecting substantially parallel to this axis, and arranged to cooperate with strips comprised in at least one vibration plate of this assembly, each pin including an actuation surface arranged to cooperate with a complementary receiving surface of a corresponding strip and the section of these strips of the vibration plate gradually increases from the shortest strip which is the highest pitched, to the longest strip which is the lowest pitched. The complementary receiving surface includes an end edge, which, at the end of actuation of the strip, is on the same radius as a complementary end edge comprised in the pin.

1. A disc-vibration plate assembly for a musical or striking timepiece, including at least one disc rotating about an axis and provided with pins projecting substantially parallel to said axis, and arranged to cooperate with strips comprised in at least one vibration plate of said assembly, each said pin including an actuation surface arranged to cooperate with a complementary receiving surface on a distal end of a said corresponding strip and said distal end is placed on the same radius of said disc as said pin, wherein the section of said strips of said vibration plate gradually increases from said shortest strip which is the highest pitched, to said longest strip which is the lowest pitched, wherein said complementary receiving surface includes an end edge, which is placed, at the end of an actuation phase of said strip, on the same radius relative to said pivot axis as a complementary end edge comprised in said pin, and wherein said end edge and said complementary end edge are line segments, wherein said actuation surfaces of said pins, and said complementary receiving surfaces of said strips, are oblique planes relative to the plane of said disc, in a local radial direction originating from the centre of said disc and passing through the point of contact between said strip and said pin concerned.
