Patent ID: 7207673

Claim:
A pair of sun glasses mounted on the brim of a cap, said pair of sun glasses comprising: a glasses member having two seat elements on the top rim of said glasses members; two joint members, each having an L-like shape with a spherical element at one end and a bolt element at the other end, said bolt element having an indented neck portion which has at least a wider side and a narrow side; and two clipping members, each being a strip having one end bended to form a hook portion for clipping the edge of the brim of said cap and a flat portion at the other end, said flat portion having a slot opening of a particular shape; wherein each joint member is attached to said glasses member by having its spherical element fitted inside said seat element; said seat elements and said spherical elements are provided such that said joint member is able to rotate around said spherical element while attached to said seat element; said shape of said slot opening allows said bolt element to penetrate through at a particular location but the rest of said slot opening allows only said narrow side of said neck portion to slide through; said clipping members are therefore extended for an appropriate distance from said glasses member by sliding said clipping members with said bolt elements inside said slot openings; said clipping member is rotated for an appropriate angle to reliably clip said wider side of said neck portion; and said hook portions of said clipping members clip the edge of the brim of said cap, thereby mounting said pair of sun glasses below said cap.
