  • Connection structure of ear upholders for eyeglasses
    Patent number: 6254235
    Abstract: The invention is an improved connection of ear upholders for integrally molded arch eyeglasses comprising a lens and a frame. The connection ends of the ear upholders form curved hooks. When the ear upholders are unfolded prior to wearing the eyeglasses, the hook rim of the connection end will gradually reach against a lateral rim of the eyeglasses frame. When the angle for unfolding the ear upholders is limited to a direction perpendicular to the eyeglasses frame, users may unfold the ear upholders and fix them in the preset right angle automatically without adjusting the positions of the ear upholders.
