Abstract: The invention relates to a guide trough for energy guiding chains, where the guide trough has parallel lateral guide elements and bottom guide elements, where the lateral guide elements are spaced apart laterally, where an energy guiding chain can be arranged in the guide trough and deposited between the lateral guide elements and on the bottom guide elements, and where a support structure with support elements is provided, on which the guide elements can be mounted, and where mounting devices for mounting the support elements on an essentially vertical surface are provided. In order to devise a guide trough which is of simple design and can be mounted on a vertical surface with minimal assembly, a guide trough is provided in which the support elements, and at least one guide element, selected from the group consisting of lateral and bottom guide element, have corresponding, integrally moulded means for mounting on one another.

Abstract: An energy supply chain for guiding conduits such as cables, hoses or the like between a stationary and a movable connection point or between two connection points which are movable relative to each other comprises a plurality of hingedly interconnected chain link members forming a space for receiving the conduits extending therethrough. The chain includes at least one bar which is resilient about its longitudinal axis and which extends in the longitudinal direction of the chain, more particularly in the receiving space thereof. Upon pivotal movement of the chain link members relative to each other the bar produces return forces which oppose the pivotal movement.
