Abstract

A method of producing a safety clutch for releasable securing of a post for a body piercing is disclosed. The post is guided through a hole in a plate to be secured (but removable) between a pair of cantilever spring elements bent from the edges of the plate into position on the back side of the plate. A dome shield is also secured to the edge of plate to cover the cantilever spring elements on back side of the clutch, the dome shield including one or more ventilation holes for reducing moisture accumulation within the dome shield. The dome shield blocks an end of the post extending between the cantilever spring elements from contacting the user and possibly puncturing skin. The plate, dome shield and cantilever spring elements can be efficiently manufactured by forming and stamping from a single piece of material.

Dependent claims

A method of producing a clutch for securing a post in a body piercing, the method comprising the steps of:

stamping and forming from a contiguous piece of planar material a plate section having a post hole therethrough and a pair of cantilever spring elements and a dome shield, the plate section and the dome shield having a connecting flange therebetween;
bending the pair of cantilever spring elements to extend from opposite edges of the plate section to be proximate to one another and aligned such that the cantilever spring elements partially intersect opposite sides of an imaginary cylindrical surface extending perpendicularly from the post hole on a backside of the plate section;
bending the connecting flange to enclose the cantilever spring elements with the dome shield such that the imaginary cylindrical surface intersects the dome shield;
and
securing the dome shield to the plate section.
