| Abstract: |
The subject invention relates to a breakaway hinge mounting for spectacles which permits the temple piece to break away from the lens frame under an impact. The hinge includes a side leaf rigidly secured to the temple piece, a front leaf pivotally secured to the side leaf, a gripper rigidly secured to the front leaf and a securing member embedded in the lens frame for engaging the gripper, thereby preventing rotation of the temple member and permitting the temple piece to break away from the lens frame when the spectacle hinge is subjected to an external force.
