Abstract
An energy line guide chain for running lines between a stationary and a movable connection, with jointed chain links of plastic, which define each a channel section extending in the direction of the energy line guide chain. Each chain link comprises opposite link plates extending in spaced relationship in a longitudinal direction of the energy line guide chain. The link plates are interconnected by at least one crosspiece. Each link plate comprises a joint body (6) and a joint receiver (7), which extend substantially crosswise to the longitudinal direction of the energy line guide chain. The joint body (6) of a link plate engages the joint receiver (7) of an adjacent link plate. Between the partially overlapping link plates of two adjacent chain links, a clearance is provided. The joint body (6) comprises two diametrically opposite outer surface areas (19). The joint receiver (7) has two diametrically opposite inner surface areas (18). The outer surface areas and inner surface areas define diametrically opposed gaps (17) which permit a lateral deflection of the chain links.
