ABSTRACT:
Folding binoculars having a pair of eyepiece frames and a pair of objective frames which are swingably supported by the rear and front edges of a pair consisting of left and right cover frames that can open and close with respect to each other. The binoculars become usable when the cover frames are swung open, thereby allowing the eyepiece and objective frames to be raised and set up by virtue of the resilience of set-up springs, and thereby aligning the optical axes of eyepieces and objectives. When the cover frames are swung to close and, accordingly, when the eyepiece or objective frames are moved toward each other to contact each other, the lens frames become guided by folding guide portions formed on the inner edges of the lens frames by virtue of contact between these guide portions, whereby the eyepiece and object frames are swung against the resilience of the springs, and they become folded and received within the frame covers. Thus, the folding binoculars can be folded to form a compact structure when they are not in use.
