ADJUSTABLE LENGTH UPPER FRAME MEMBER FOR EYEGLASSES

摘要

A frame assembly for eyeglasses (10) is provided wherein the overall width of the eyeglass frame is adjustable by utilizing a telescoping brow bar (74). The upper frame member (74) or brow bar is formed to include either a pair of telescoping or indexed joints allowing the length of the brow bar (74) to be adjusted thereby placing the hinge points (84) and temple bars (18) further apart from one another. The adjustable length of the brow bar (74) provides excellent adjustability of the overall width of the eyeglass frame in simple mechanical construction. Further, in a unique method of forming the adjustable brow bar (74) assembly a central portion may be formed in a first molding step and an adjustable hinge section is then molded directly over the central portion in a second molding step. The present invention utilizes in-mold-assembly techniques to reduce the assembly steps required to form such an adjustable brow bar assembly while further resulting in an eyeglass frame that has increased adjustability and utility.
