Title: Wire-frame eyewear assembly with transversely-lithe sidepiece element

Abstract: This invention is a completely mechanical method of constructing eyewear,without brazing. An eyewear frame is formed by a continuous, bent, springwire. Sidepiece 47 is fixedly attached to frame endpiece parts 30 and 31by mating a bent portion of each within compression spring 40. TheVertically tall, transversely thin sidepieces can support with scantlateral pressure to a wearer's head, and can close can close against theframe without hinges. The length of a spring over the endpiece confineslense 56 in upper and lower portions of a frame's eyewire. Lense 55 hasbeen removed by laterally compressing spring 40 around the folded-overendpiece parts and letting the ends of the endpiece parts spreadvertically apart. Elongated members, unrelated to eyewear endpieces andsidepieces, can be fixedly attached and removed, and/or spread in the waysdescribed above. A nosebridge can be formed by a continuous, bent, springwire. It's transversely elongated bridgeportion 20 adds strength andstability to the frame. Hook 22 at an upper lateral end of thebridgeportion plus a bridgeportion frontward bow substantiallymechanically encircle the frame's bridge in the latitudinal/longitudinalplane. The hooks and bow hold together upper and lower medial portions ofa frame's eyewire. The vertical stability of the lenses, supported in theframe's eyewires, keeps the nosebridge from rotating. Nosebridge hook 22continues downwardly/rearwardly as nosepad arm 60. The lateral angling ofthe arms also keeps the nosebridge from rotating. Each wire end of thearms upwardly loop; each loop can secure a nosepad balljoint.
