ABSTRACT:
An easily-adjusted spectacle frame, designed to co-operate with the compact and lightweight binocular of patent application Ser. No. 344,062, now U.S. Pat. No. 4,488,790, entitled BINOCULAR AND SPECTACLE TYPE MOUNTING ASSEMBLY THEREFOR, of which this application is a continuation in part. A primary object of the invention is to permit accurate alignment before the eyes of the user of a high performance 7 power binocular for wearing comfort comparable to that in ordinary eyeglasses. This requires that the binocular have the hinge connecting the paired telescopes tapped for a set-screw, which slides in a verticle slot located at the nose bridge of the spectacle bow. This adjusts for the up-and-down movements of the eyepieces as the binocular hinge is opened and closed to accommodate the varying interpupillary requirements of users, whether the eyes be close together or wide apart. A major feature is that the spectacle frame is completely unseen by the wearer.
