Abstract: A magnetically actuated locking mechanism includes a male section and a female section releasably coupled to the male section. The male section includes a male body, a projection extending from one end of the male body and including a transverse bore, and a locking element movable between an unlocked position wherein the locking element is received within the bore and a locked position wherein the locking element is partly extracted from the bore. A first magnet is embedded in the locking element. The female section includes a female body having a guide cavity dimensioned to receive the projection, and a transverse locking recess dimensioned to lockingly receive a part of the locking element as extracted. A second magnet is embedded in the female body adjacent to the locking recess.

Abstract: An adjustable eyeglass frame includes a lens frame assembly adapted to hold a pair of lenses, and a nosepiece assembly including a pad mount attached to the lens frame assembly. The nose piece assembly has a pair of legs connected to the pad mount, a pair of nose pads carried by the legs and pivotably movable toward and away from each other, and a bias mechanism for biasing the nose pads toward each other so that the nose pads are safely held in any selected vertical positions.
