ENERGY DRAG CHAIN

摘要

The invention relates to an energy drag chain for guiding tubes, cables or t he like, comprising a number of chain members (2). Neighboring chain members ar e hinged to each other and are provided with flat links (3) with inner and out er lateral faces and front faces that are perpendicular thereto and substantial ly parallel to the longitudinal direction of the chain. At least some of the chain members have at least one crossbar (4a, 4b) interlinking the flat link s and the hinged joint of neighboring chain members is disposed on the front faces of the flat links. The energy drag chain can be displaced while formin g a lower strand (5), a deflection zone (6) and an upper strands (7). The aim of the invention is to provide an energy drag chain with hinged joints that are disposed between the front faces of the flat links of the chain that can be displaced with little wear and little friction and that is simple and inexpensive in production. To this end, the chain members (1) are configured as elastically deformable joint elements (8) that are produced as separate components and that extend at least partially or preferably exclusively between the inner and outer lateral faces of the flat links (3). The joint elements (8) can be disposed in laterally open recesses of the flat links.
