ABSTRACT:
Plastic sunglasses comprise a transparent lens piece, a pair of temple pieces attached to the ends of the lens piece, and an opaque visor which snap-locks onto the top of the lens piece. The visor has a long curved front face with L-shaped ends, an angular top face for projecting inwardly across the top of the lens piece, and separate hooks projecting inwardly from the inner ends of the visor behind corresponding L-shaped shoulders. A visor connector at the top of the lens piece includes a curved upright wall with generally L-shaped ends. The wall is recessed from a curved ridge with generally L-shaped ends extending across the front of the lens piece. The opposite ends of the visor connector include L-shaped slots in its bottom front face which interlock with the L-shaped shoulders on the bottom inside face of the visor. The visor is interlocked with the visor connector by engaging the shoulder at one end of the visor with a corresponding slot on the lens piece, engaging the hook at the opposite end of the visor with a rear edge of the lens connector wall, and pressing down on the opposite end of the visor so the hook and shoulder move downwardly and apply tension to the end of the visor until the shoulder in front of the hook snap-locks into the slot at the opposite end of the visor connector.
