Binoculars with split adjustable ocular bridge - have means for storing setting data for different persons

摘要

The ocular bridge is in two parts and is designed so that each part is adjustably supported with its ocular on a central hinge pin and each part has its own switching cam. The hinge pin carries a revolving drum with individually adjustable pairs of spindles on its periphery. The spindles act through the switching cams on the ocular bridge depending on the position of the drum to move the oculars into a previously adjusted correct position for the user. The pairs of spindles are pref. concentric with each other. The entire system is loaded by a coil spring. Two springs may be used.
