Abstract
An energy guiding chain for guiding hoses, cables or the like has numerous chain links ( ), connected to one another in articulated fashion. Each chain link has opposing straps ( ) with inside and outside lateral surfaces as well as narrow surfaces perpendicular to the lateral surfaces and essentially parallel to the longitudinal direction of the chain. At least some of the chain links have at least one cross-member ( ) connecting the opposing straps. The articulated joint includes joint elements ( ) which extend between adjacent straps. The joint elements are elastically deformable in the bending direction of the chain links ( ), and extend at least partially, preferably entirely, between the inside and outside lateral surfaces of the straps ( ). The joint elements ( ) can be located in laterally open recesses in the straps. In this manner, the energy guiding chain can travel to form a lower strand ( ), a deflection zone ( ) and an upper strand ( ).
