US 2003/0117727 A1 · Tube assembly for an optical instrument having at least two rotary joints

Abstract

The invention relates to a tube for an optical instrument, such as a microscope, having several rotary joints (19, 20, 21) connected serially one behind the other. Each of the rotary joints (19, 20, 21) includes a brake (32, 33, 38) via which the rotary joints are secured against an unintended rotation. The brakes of the rotary joints (19, 20, 21), which are connected serially one behind the other, are simultaneously releasable by actuation of the single operator lever (39). For this purpose, a system of pins (42) and tilt levers (43) is mounted in the tube via which the actuation of the operator element (39) is transmitted to the brakes (32, 33, 38) connected serially one behind the other.
