发明名称 Spectacles with single pivot folded rear vision elements
摘要 A fashionable pair of spectacles with single pivot folded rear vision elements for viewing objects behind a forward facing user. The spectacles are comprised of a binocular eyepiece of the kind having a conventional frame without side shields, a pair of spaced apart slender temples mounted to opposite ends of the eyepiece for rotation about a first pair of vertical axes and a pair of spaced apart folded elements mounted to the eyepiece for rotation about a second pair of vertical axes which are positioned inside of the first pair of axes. Each rear vision element has a reflective portion and a mounting portion at a fixed angular relationship to the reflective portion. The elements are independently selectively adjustable about the second set of axes to operative positions for viewing objects behind the wearer whereat the reflective portions are forward of the eyepiece in plain view without restriction to the side vision of the user and to non-operative stored positions whereat the reflective portions are in side facing relationship to the user. When the elements are at their non-operative stored positions the appearance of the spectacles is conventional and the folded elements are not readily discernible as separate elements of the spectacles.
