Abstract
A mechanism for use in an elevator governor assembly including a ground configured to rotate about a ground axis, three or more circumferentially overlapping cams each pivotally attached to the ground at one of three or more ground pivot points radially spaced from the ground axis, and a plurality of links pivotally attaching the three or more cams to one another at a plurality of link pivot points. The circumferentially overlapping cams form a substantially contiguous circular ring about the ground axis. The interconnection of the ground, the cams, and the links form a generally circular mechanism.
