Abstract
A portable periscope has a body divided by longitudinal and transverse fold lines. The body can be folded inwardly along the longitudinal fold lines to produce an erect periscope frame having a rectangular cross section. End flaps on either end of the frame hold mirrors which are inclined inwardly toward the front or back wall of the frame. The mirrors are positioned so that they are in opposed relationship allowing the user to view a desired scene by looking into the lower mirror. Folding the frame along two opposite longitudinal fold lines and along the transverse fold lines allows the frame to be collapsed into a generally flat structure so that it can be placed into the pocket of a user. Two pairs of structural wings mounted at lateral portions of the end flaps are detachably connectd to the lateral walls of the frame and when so connected both hold the mirrors in the desired inclined position and prevent the frame from being folded along the longitudinal fold lines thereby prevent collapse of the periscope.
