ABSTRACT:
A jewelry clasp in which a blade member is captured in a case member by a latch normally located in a latched position to secure the blade member in the case member, the latch being displaceable along a first direction in response to movement of the blade member into the case member for latching purposes and displaceable along a second direction transverse to the first direction, in response to a selectively moved actuator, for unlatching purposes, to selectively release the blade member from the case member, a first spring biases the latch along the first direction and a second spring biases the latch along the second direction for maintaining the latch in the latched position, and a safety lock is movable selectively from an unlocked position into a locked position for precluding inadvertent unlatching, while permitting latching independent of the position of the safety lock.
