Jewellery setting lock-attaching structure - has shaft male member with transverse slit engaging with legs within female receptacle

摘要

The structure is for the use in mounting ornamental stones in a setting on a base member such as a ring. The structure defined on one of opposing mateable male and female member includes a shaft male projection with a slot extending transversely of and around the shaft male projection. The female member has a receptacle defining a space sufficiently large to include inwardly spring-biased legs with ends engageable within the shaft slot when the shaft is slid into the space to lock the shaft in the inserted position until the opposing legs are prized apart by depression of a downwardly-directed and extending wedge-leg into a lateral movement between the leg ends in a wedge manner such that the leg structures are forced apart sufficiently for the shaft to be withdrawn.
