ABSTRACT:
Folding binoculars in which left and right eyepiece frames, each carrying an eyepiece, are swingably supported in such a manner as to be able to open and close with respect to each other, and objective frames, each carrying an objective, are mounted on the eyepiece frames in such a manner as to be able to project from and retract into the eyepiece frames. When the eyepiece frames are swung open, the objective frames are projected to and fixed at the front portions of the eyepiece frames, thereby bringing the optical axis of the objectives into alignment with those of the eyepieces, and thereby rendering the binoculars usable. When the binoculars are not in use, they can be folded to form a compact structure by moving the eyepiece frames toward each other to close.
