ABSTRACT:
A reinforced eyeglass frame assembly having a frame front and temple members, a pair of hinge members pivotally coupling the temple members to the frame front between open and closed positions, and a pair of reinforcing tubes slidably coupled to the temple members. When the temple members are in their closed positions, the reinforcing tubes are located in their first positions spaced from the hinge members allowing for free pivotal movement of the temple members. When the temple members are pivoted to their open positions, the reinforcing tubes are moved to their second positions surrounding the hinge members and locking them against pivotal movement. The tubes and hinge members are sized so that the tubes frictionally engage a part of the frame front and the hinge members, when in their second positions, to retain the tubes over the hinge members. The reinforcing tubes are preferably formed of a polymeric material, such as polycarbonate, that is stronger and stiffer than the polymeric material forming the frame front and temple members, such as cellulose acetate.
