Abstract:
An energy line guide chain for running lines between a stationary and a moveable connection comprisinga plurality of interconnected plastic chain links, each chain link including two laterally spaced apart and parallel link plates extending in a longitudinal direction, and at least one crosspiece interconnecting the link plates, with the link plates of each chain link partially overlapping respective link plates of each longitudinally adjacent chain link, and with each link plate including a joint body and a joint receiver adjacent respective opposite ends of the link plate, with the joint body of each chain link engaged within a joint receiver of an overlapping link plate so as to define a joint axis which extends between the link plates and is perpendicular to the longitudinal direction, with a clearance formed between opposing faces of the overlapping link plates of adjacent chain links, and wherein each interengaging joint body and joint receiver defines adjacent surface areas which include two diametrically opposed gaps and two diametrically opposed contact areas where the adjacent surface areas are in contact and which define a pivot axis which is perpendicular to the longitudinal direction, and to the joint axis, so that the adjacent chain links can pivot relative to each other about, the joint axis and the pivot axis.
