Abstract
A friction control mechanism for an articulating arm including an arm, a pivot connector, an axial washer, and at least one set screw. An axial washer is placed around each side of a center aperture in the pivot connector. The pivot connector is connected to the arm with a pivot pin through the center aperture in the pivot connector and aligned holes in the first and second sides of the arm. At least one threaded hole is located adjacent the aligned hole in the first side of the arm. A set screw is placed through each threaded hole, making contact with the axial washer. This contact creates a friction force between the pivot connector and the axial washer, keeping the articulating arm from drifting away from its set position. The pivot connector may be connected to another device such as another arm or a machine such as an x-ray machine, or to another pivot connector.
