<p>This invention concerns a frame for spectacles comprising one or more flexible elements fitted between parts of the front and of the sides, in order to make the frame itself highly adaptable to the anatomy of the face; said flexible elements comprise a helical spring (10) and two pins (11 and 11'), one end of which engages with said spring (10) whereas the opposite end is secured to said parts of the front and of the sides (14 and 14'); the threaded ends (12 and 12') of said pins are equal in diameter (d) to the internal diameter of said spring (10) and have a pitch equal to the pitch of the coils of said spring, whilst their combined length (11 + 12) is less than the length (13) of said spring.</p> |
