摘要

A spectacle frame comprises mountings(11) for the lenses(L) and a pair of sides(3) fastened to the mountings by means of respective hinges(7) having a rotation axis in which each of the hinges is formed from a first portion of wire wound into a helical spring(11D) and from a second portion of wire forming a hinge pin(3A) that fits into the helical spring, one of the portions of wire extending to form the respective side and the other portion of wire having a connection member for the connection to the mountings. The portion of wire forming the side has a bend(3C) which defines a first abutment against the connection member to retain the pin into engagement with the helical spring and a second abutment to limit the aperture of the side.
