Jewelry clasp

Claim 1

A clasp comprising, two main parts (a) a receptor, (b) a spring clip, the receptor having an opening at one end and a downwardly directed stop element at the top of the opening, the spring clip having an end insertable into the opening, and including a bottom element and a spring finger return-bent about a curved interconnecting element, the spring finger being self-biased to an upper locking position in which it engages said stop element when the spring clip is in position in the receptor in response to its insertion thereinto, and thereby releasably locking the spring clip in place in locking position, receptor including a release member of small mass extending transversely therethrough and having ends exposed laterally of the receptor for gripping thereof by the fingers of the user, and slideable longitudinally of the receptor, from a retracted inactive position to an advanced operative position, and in so sliding, operative for camming the spring finger out of locking position, and the spring finger being made up of end portions that are substantially straight longitudinally, and an intermediate portion inclined at an abrupt angle to the longitudinal direction of the end portions, forming an abutment operative, pursuant to insertion of the spring clip into the receptor and consequent engagement with the release member, for moving the release member to retracted position, but functioning as a camming element in response to movement of the release member thereagainst and thereby enabling the release member to release it from locking position.
