MECHANISM FOR ADJUSTING BINOCULARS FOR SHARPNESS Russian patent published in 1995 - IPC

FIELD: binocular observing devices. SUBSTANCE: when pressing on one key, for example, lever-key, the lever endures resistance of the spring and rotates together with ratchet tooth of the lever, until the tooth rests against the tooth onto small drum, and its protrusion- against the cup from inside. At further pass of key-lever, the key rotates small drum and bushing together. As a result, screw axis shifts, as well as eye-pieces. In order to shift eye-pieces to the other side, key of the cup should be pressed. EFFECT: improved precision. 4 dwg
