ABSTRACT:
An improvement in post-type earrings, which are earrings connected to a human ear by a rigid slender short rod or post which extends from an ornament, and is rectilinear and cylindrical. The post is threaded at the end opposite to the ornament, and a clutch having a conical configuration formed by a concave base and a plurality of radial springy fingers is provided. The clutch is pushed onto the post, whereby the tips of the fingers engage the convolutions of the helical threading, and the clutch may only be removed by unscrewing it off of the post. The present clutch configuration features a concave base for self-locating of the post; an octagonal base perimeter for facilitating grip and unscrewing; convex rounded tips on the fingers; a center longitudinal ridge on each finger for increased strength and less weight; lateral end ridges adjacent the finger tips to prevent degradation or bending of the tips; and lateral base ridges on each finger which improve flexibility.
