Abstract
The invention concerns an energy guide chain for guiding hoses, cables or lines comprising chain links ( ) each consisting of two link plates ( ) and at least one crossbar ( ) connecting the link plates, wherein link plates ( ) of adjacent chain links ( ) have pivot regions comprising mutually corresponding pivot pins ( ) and openings ( ) for receiving the pivot pins, by means of which the chain links ( ) are pivotably interconnected, and wherein the link plates ( ) of adjacent chain links ( ) have mutually overlapping overlap regions ( ), forming lines ( ) of link plates, and wherein at least one link plate ( ) is provided with a region ( ) of weakened material, which permits a variation in length of the link plate line ( ) beyond the play which occurs in the pivot region ( ) in all directions of the link plate ( ). In order to permit improved straight-ahead movement of the chain the material-weakened region ( ) is in the form of an elastically deformable region of the link plate ( ). The elastic region can be in the form of a cross-sectional constriction of the link plate ( ), which extends over the entire height thereof.
