ABSTRACT:
Disclosed is an improved bridge structure of spectacles frame, which frame has a bridge and a transverse piece both connecting two rims side by side. It comprises a joint piece and opposite arms, each arm being fixed to one or the other rim at one end, and being fixed to the joint piece at the other end so as to permit the arms to rotate relative to each other. The rotatable bridge permits the frame to yielding twist when exterior force is applied thereto, and to restore to its original shape when the exterior force is removed therefrom.
