ABSTRACT:
Super-slim folding spectacles comprising two symmetrically arranged spectacle frames and perpendicularly assembled temples, in which the two frames are assembled with a hinged joint in two parts, one of which has a spring pin protruding out of a blind hole in a groove and rolling over an arched end of the other part until it sticks in a notch of a groove to thus fix the two frames in an unfolded position is disclosed. The frames can be easily, horizontally folded until they are parallel in a common plane and close together with their temples separately folded and lying across them. The folded spectacles, which are small and thin in size and conveniently arranged for carrying and storing, are practical and considered a brand-new design.
