ABSTRACT:
A mechanism forming the hinges between an eyeglass frame and the lateral temple bars which allows for the rapid adjustment of the vertical alignment of the lens frame in relation to the horizontal axes of the temple pieces. The forward end of each temple piece is split into a stationary half and a sliding half. Each half terminates into a pin or ball which cooperates with a bearing at the edge of the lens frame to form a hinge allowing each temple piece to be folded against the frame. The sliding halves can be moved along the axes of the temple pieces independently from the stationary ones to tilt the hinging axis so as to change the position of the lens plane in relation to the temple pieces.
