Abstract
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 and two pins, one end of which engages with said spring whereas the opposite end is secured to said parts of the front and of the sides; the threaded ends of said pins are equal in diameter to the internal diameter of said spring and have a pitch equal to the pitch of the coils of said spring, while their combined length is less than the length of said spring.
Claims5
A spectacle frame comprising:
- (a) first and second rim portions for holding lenses therein;
- (b) first and second pin means, said first and second pin means each having an embedded end portion completely and fixedly embedded in a corresponding one of said first and second rim portions, and having an extending portion extending from said corresponding first and second rim portions, said extending portions having screw threads thereon;
- (c) helical spring means having a length greater than the sum of the lengths of said extending portions, wherein the extending portions of said first and second pin means each threadedly engage a predetermined length of said helical spring means thereby coupling said first and second rim portions together for forming the bridge of said frame, wherein the fixed embedding of said first and second pin means in said rim portions prevents the further relative rotation of said first and second pin means with respect to said rim means of the assembly;
- (d) nose piece means mounted on said first and second rim means for supporting said first and second rim means on the nose of a user;
- and
- (e) first and second temple piece means each having one end coupled to a corresponding one of said rim means, said temple piece means being adapted to engage the ears of a user to support the frames thereon.
