Abstract

A pair of eyeglasses having a pair of lenses, a frame for the lenses, nose pieces disposed between the lenses and adapted to engage the bridge of the nose of a wearer, and a pair of temple pieces extending rearwardly over the ears of the wearer, said temple pieces consisting of either a single continuous piece with the rearward end terminating in a thin tapering hook member fitted with a movable semi-soft weighted sleeve, or with temple pieces consisting of two segments, a forward section connected by the usual hinged means to the frame holding the lenses, and a rearward section terminating in a solid hooked member made of heavy material and with a soft cushion attached underneath, said members being connected by means of a sleeve permitting of horizontal adjustment, and located at an arbitrary point between the plane of the lenses and the ears of the wearer, and the designs of the temple pieces described above resulting in lessening weight and trauma at the nose of the warer of the glasses, the elimination or reduction of soreness and feeling of weight at the ears, ease of adjustment, and a means of keeping the lenses in a proper position for maximum optical effectiveness.

Claims3

Dependent claims

In a temple piece for a pair of glasses, said temple piece terminating in a hook receivable over the ear of the wearer, the improvement wherein the said temple piece is substantially rigid and terminates in a thin, tapering hook member for receiving a weighted semi-solid sleeve, said weighted sleeve comprising a semi-solid sleeve-like envelope of tapered design, said envelope containing a mixture of rubbery material and heavy, inert powdered material, said weighted envelope defining a tapered narrow inside space for snugly receiving said tapering hook member, the arrangement being that the top of the ear of the glasses wearer serves as the fulcrum for the glasses, the said weighted sleeve being of sufficient weight to move the balance of the glasses to a point along the temple piece nearer to the ears of the wearer than to the opposite end of said temple piece, said weighted sleeve fitting snugly on said tapering hook member, the arrangement being such that said weighted sleeve is movable as a means of longitudinal adjustment of said temple piece by a wedging action behind the ear of the wearer, the wedging action being due to the tapered hook member received within said narrow inside space of said weighted envelope, said sleeve serving as both counterweight and cushion.
