ABSTRACT:
A guide chain for guiding energy lines, with the guide chain being disposed between a fixed connection and a movable consuming device. The guide chain includes a plurality of interconnected chain link members, each of which is a one-piece, inherently stable, U-shaped receiving member having two legs that are connected by a crosspiece and that form the links of the chain link member. Each of the chain link members is provided with a stop to limit the two-way pivot angle of adjacent interconnected ones of the chain link members. Each link of a given chain link member has a first end connected to the crosspiece, and a second end. A respective holding element is disposed on each second end of each link of a given chain link member. Each holding element projects inwardly toward the other link of that chain link member. A flexible cover strip is retained between the holding elements in a self-supporting manner for spanning the open portion of each chain link member. Each holding element can be a projection that is either provided with a slot for receiving a cover strip, or that is provided with undercuts for receiving widened edge beads of the cover strip.
