Abstract
A non-rotatable telescoping support structure particularly suited for use in a pole lamp includes an outer elongated tubular member having a bore of cross section the shape of a convex polygon and an inner tubular component having an outer surface with a cross section of shape corresponding to the cross-sectional shape of the outer component bore. The inner component is slidable within the bore of the outer component but relative rotation is prevented by engagement of the corner of the inner component with the inner surface of the outer component adjacent to the corner of the outer component bore. One end of the outer component has external threads on which a split ring assembly is threaded and tightened to deter relative longitudinal movement between the inner component and the outer component.
