ABSTRACT:
Unlike conventional snap fasteners, this clasp's mechanism temporarily locks to prevent opening by accidental forces which apply unevenly and tilt the socket against the elongated stud that passes through and beyond the socket. Designed for general use, it is especially valuable for bracelets. While accidental opening is virtually impossible, stud and socket support-bodies make intentional opening easy, with one hand. With bracelet between them, middle and index fingers hold the socket support-body on opposite edges, without blocking stud movement, while thumb pressure is applied to the protruding end of the stud to eject it and open the clasp. This procedure keeps axes of stud and socket sufficiently aligned to avoid the locking effect, and automatically leaves the wearer holding the socket side of the clasp to avoid dropping the bracelet. The support-body means of attachment makes pull from chain or bracelet substantially perpendicular to clasp's opening direction.
