Pivot arm stand for digital microscopes

摘要

The invention relates to a pivot arm stand for digital microscopes having a pivot arm which is pivotable about a rotation axis. According to the invention the pivotal movement may be blocked by a high torque magnetic brake arranged about a rotation axis (DA), which consists of a simultaneously pivoting part (MS) and a fixed part (ML), whereby the blocking may be suspended for the duration of a touch of a button (TS) by releasing the high torque magnetic brake, the button (TS) being arranged on the pivot arm (SA) in such a way that it can be conveniently pressed with at least one finger of the same hand which clasps an ergonomically shaped section (EB) of the pivot arm (SA), which is provided for grasping the pivot arm (SA) for setting a pivot angle (w).
