Abstract: An improved eyeglasses construction including molded plastic temple assemblies each having a hinged joint intermediate its ends for limited pivotal movement permitting adjustment of the lens frame about the horizontal axis of the hinged joint. One piece of each temple assembly has a bifurcated end providing a pair of spaced flanges having parallel opposed vertical surfaces, and the other temple piece has a flat tongue-like member projecting from its end and including a generally C-shaped opening adapted to snap over the hinge pin to hingedly connect the two pieces in end-to-end relation. A spring arm on the bifurcated piece projects in overlying relation to a flat surface of the tongue-like member and carries a detent which is urged into engagement with a pattern of ridges and/or grooves on the surface of the tongue-like member to permit adjustment about the horizontal axis of the hinge pin.

Abstract: Angularly adjustable temples are disclosed which can be attached to a pair of eyeglasses. Each temple includes an end which is hinged to the eyeglasses for rotation inwardly along the lens of the glasses. Each temple includes first and second parts having compatible ends that fit together and which are adjustable angularly with respect to each other. One end of the first part includes a shaft disposed between parallel walls and a short pin projecting from one of said walls. The second part includes an end having a jaw member that fits between the parallel walls and is fitted on the shaft. The parallel walls of the first part include a series of serrations thereon which are compatible with a hook-like protrusion on the second part in order to fix the second temple part at an adjusted angle relative to the first temple part.

Abstract: A safety goggle assembly in combination with a pair of glasses including corrective lenses. The safety goggles have at least one lens formed of a safety type material. The corrective glasses have at least one lens in a frame in which the frame is form with a bridge portion that fits tightly over a bridge of the goggle. The corrective glasses include an upper bar which fits behind a protruding member in a forehead portion of the goggle. Therefore, the corrective glasses will be secured within the goggle between the bridge and the forehead portion without the use of special securing elements.

Abstract: A prescription lens attachable to a safety glass frame. The safety glass frame is provided with a single lens, a center cross pin and indentation on an inner surface of the safety glass frame juxtaposed the temple pivot pin. A prescription frame includes separate prescription lenses and a central clip that clips onto the cross pin of the safety glass frame. The outer ends of the prescription frame are provided with angular locking ends that are pressed into the indentation on the safety glass frame. Thus, the prescription lens frame is held securely onto the safety glass frame between the safety glass frame and the persons eyes. Damage to the safety glass lens or frame necessitate replacement of only the non-prescription safety glasses because the prescription frame can be removed from the damaged frame and secured to a new safety glass frame.

Abstract: A pair of glasses to which an eyeglass accessory is secured by use of at least one T-slot on the pair of glasses and a complementally-shaped T-bar on the eyeglass accessory. In a preferred embodiment the eyeglass accessory allows corrective prescription lenses to be mounted inside a pair of safety glasses.
