  • Patent number: 6425664
    Abstract: A folding device of glasses includes a body having two frames, and two temples that may be folded and expanded. Two magnetic attraction structures are mounted on the two temples, so that the two temples may magnetically attract each other when the glasses are disposed at a folded status. In such a manner, when the glasses are disposed at a folded status, and are hung on the pocket of a clothing, a first temple is placed in the pocket of the clothing, and a second temple is exposed outward from the pocket of the clothing, so that the two temples may attract and bond each other by the magnetic attraction structures to secure the glasses on the pocket of the clothing. Thus, the glasses can be rigidly and safely placed in the pocket, and can be removed from the pocket conveniently.
