| Abstract: |
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.

We claim:
1. A pair of spectacles for viewing objects behind a forward facing user of the kind having a pair of slender temples rotatably attached to the ends of a conventional eyeglass frame without side shields whereby the side vision of the user of the spectacles is unobstructed by the frame, comprising, in combination: an eyepiece, a conventional eyeglass frame without side shields, a pair of symmetrically opposite slender temples attached to the opposite outer end portions of the frame for rotation about a pair of spaced apart axes, a pair of lenses mounted in the frame, at least one folded rear vision element attached to the eyepiece at a position which is laterally intermediate to the ends of the frame, said rear vision element having a window bounded by a pair of spaced apart arms rotatably attached to the upper and lower intermediate portions of said frame to enable the user through the window between said arms to view objects at the side of the user without obstruction and an adjoining reflective portion at a fixed angular relationship to said arms to enable the user through said lenses to view objects behind the user, said element being selectively adjustable about a single axis to an operative position whereat said reflective portion is in confronting relationship to a user of said spectacles and to a non-operative position whereat said reflective portion is in side facing relationship to the user.
