Classification: CPC F  H | IPC F  H

Claim 24:
25. An energy chain to guide at least one line, comprising:
two link plate strands comprising alternating inner link plates and outer link plates, which are connected swivelably to each other by flexible connections,
wherein at least some of the outer link plates have cross webs holding the outer link plates respectively parallel to one another,
wherein the energy chain is displaceable such that the energy chain forms opposite strands as upper and lower strands, and a deflection area connecting the upper strand and the lower strand,
wherein, to facilitate a rolling action when the energy chain is displaced, at least the upper strand and/or the lower strand comprises a plurality of rollers, which project beyond narrow sides of the inner and outer link plates in a direction of the respectively opposite strand,
wherein each roller is arranged respectively on a pair of outer link plates of the outer link plates, comprising a first outer link plate and an adjacent second outer link plate, swivelable in relation to one another, and the flexible connection of the pair of outer link plates comprises a joint pin, which is formed in one piece with the first outer link plate, and a corresponding joint mount, which is formed by the second outer link plate, wherein the joint pin engages in the joint mount and is swivelable therein,
wherein the second outer link plate has a sleeve-like annular projection coaxial with a swivel axis, wherein the sleeve-like annular projection forms the joint mount, on which each roller is supported rotatably with a rotary axis of the roller coaxial with the swivel axis.
