<p>Each projecting bridge section of both telescopic sections is provided with two dovetailed indentations arranged concentrically to the articulate shaft the symmetrically to each other. Two circular guide elements, which are part of the articulated shaft, engage in the indentations and are shaped accordingly. The cross-section of each dovetailed indentation features a tilt with the apex towards the appropriate tube or the articulated shaft. The shape and size of the indentations of both bridge sections are indentical. Both circular guide elements or their dovetailed abutments can be adjusted relative to each other in the direction of the articulated shaft.</p> |
