Abstract:
1. An energy guiding chain, to guide hoses, cables and the like, comprising: a number of chain links connected to each other in articulated fashion, said chain links being formed by side straps, which are parallel to each other and connected to form parallel side strap strands, and cross-members having opposing ends connected to the side straps, wherein the side straps are pivotable relative to each other about a pivoting axis common to two adjacent side straps, wherein the energy guiding chain is transversable in such a way that the energy guiding chain forms a loop having an upper strand, a lower strand and a deflection zone connecting the upper strand and the lower strand, as a result of which an inner side and an outer side in relation to the loop is defined on the chain links, wherein the upper strand rests on the lower strand, this involving at least partial contact of the inner sides of the chain links, and wherein the cross-members on the outer side of the chain links are detachable from the side strap at at least one of the ends of the cross-members and pivotable in order to open the chain links, while the cross-members on the inner side of the chain links are permanently connected to the side straps, wherein rollers are recessed into at least some of the side straps, said rollers projecting from a narrow face of the side straps and being rollable on the narrow faces of the side straps of the opposite strand during traversing of the chain, wherein the ends of the cross-members are provided with extensions displaying journals, and inner surfaces of the side straps are provided with undercut recesses engageable with the journals of the cross-members facing the inner side of the loop to establish a permanent connection of the inner cross-members, whereas the cross-members facing the outer side of the loop are inserted into openings in the narrow faces of the side straps, where they are retained elastically and pivotably by a snap nose.
