Abstract:
1. A cable duct for cables or cable lines to be laid along walls, partitions, and tops of subterranean tubes, vaults, tunnels, ducts, or shafts extending generally horizontally, diagonally ascending, diagonally descending, curved or with bends, for conducting at least one of water, sewage, energy and electrical transport lines, telephone lines, data and information transfer lines, glass fiber cables, optical conductor cables, and cable lines, the cable duct being inserted or pulled in from a surface into the tube, the vault and the like through generally vertical or diagonal access or branch shafts respectively and fastened to the wall, the partition or the top, the cable duct comprising: a drive chain in a manner of a bicycle drive chain, said drive chain having longitudinal cable duct body elements disposed one behind another in a longitudinal direction, said cable duct body elements having end regions connected to one another about a pivot axis disposed generally at a right angle to the longitudinal direction and being mutually pivotable relative to one another at a lateral angle, each of said cable duct body elements having a web and two cover plates spaced from one another by said web and held parallel to one another and joined together by said web, said cover plates each having longitudinal edges with locking elements disposed along said longitudinal edges, said locking elements selected from the group consisting of interlocking elements and counter locking elements; covering elements, selected from the group consisting of edge cover strips and cover profiled strips, formed of a bendable or elastically flexible material and disposed on both sides of said cable duct body elements, said covering elements having longitudinal edges with cover locking elements disposed along said longitudinal edges and continuously passing through said locking elements of said cover plates of said cable duct body elements resulting in a form-locking connection between said locking elements and said cover locking elements, said covering elements laterally closing off said cover plates on both sides and are disposed on both sides of said web between said cover plates, said cover locking elements being selected from the group consisting of interlocking elements and counter locking elements; said covering elements, said cover plates and said web defining first laterally open chambers toward both sides for receiving the cables or the cable lines; and two of said cable duct body elements separated from one another by said respective web, defining said bicycle drive chain, being mutually pivotable at said lateral angle and defining continuous longitudinal chambers, closed generally all around, for inserting and housing the cables or the cable lines.
