1. Flexible tube system which is capable of being bent to one side and serves to receive flexible energy-conducting leads (2), containing a) a first tube (3) in which parts which follow one another in the longitudinal direction of the tube have in their cross-sectional profile a groove (8) which is open towards the interior and a groove (9) which is open towards the exterior interengage with their arms (10, 11) defining the axial ends of these grooves in such a way that adjacent parts of the tube are capable of limited movement and pivoting with respect to one another, b) an element which is arranged on the inner face of the curve of the first tube (3) and is connected to at least some parts of the first tube in such a way that the parts of the first tube on the inner face of the curve are always completely compressed and the parts of the tube on the outer face of the curve are completely compressed in the extended state of the flexible tube system, characterized by the following features : c) the element according to feature b) is formed by a second tube (4) the construction of which corresponds to feature a), d) the second tube (4) on the inner curve is connected to the first tube (3) on the outer curve in such a way that the parts of the second tube are always completely expanded on the outer face of the curve and are completely expanded on the inner face of the curve in the extended state of the flexible tube system. |
