Abstract
A temple bar construction for a pair of eyeglasses includes telescoping front and rear portions. The front portion has a generally rectangular tubular configuration, and the rear portion is slidably received therein. The front portion includes a plurality of longitudinally spaced positioning slots in a bottom surface thereof and the rear portion includes a detent on the bottom edge thereof which is receivable in the positioning slots in the front portion for adjustably securing the relative positions of the front and rear portions. The rear portion has a longitudinally extending opening formed therein in closely inwardly spaced relation to the bottom edge. The opening forms a thin resiliently deflectable spring blade along the bottom edge for resiliently biasing the detent which is disposed at a midpoint on the spring blade. The front portion further includes a longitudinally extending guide slot on an inner side thereof and the rear portion further includes a laterally extending guide pin on an inner side thereof receivable in the guide slot for limiting longitudinal travel of the front and rear portions. The rear portion further includes a curved, vertically extending groove in an inner side surface thereof for permitting lateral deflection of the rear portion so that the guide pin is removable from the guide slot for insertion and removal of the rear portion from the front portion.
