Energy guide chain comprising inner and outer plates with integrated limit stop system

An energy guide chain for guiding lines, such as hoses, cables or the like, between two connection points, with chain links which in each case comprise two opposing plates, of plastics material, the plates being connected together, in the case of at least some of the chain links, by way of at least one crosspiece, the energy guide chain having two plate strings in each case with inner plates of plastics material and outer plates of plastics material succeeding one another alternately in the longitudinal direction, the inner plates having two inner overlap regions facing the inside of the chain and the outer plates having two outer overlap regions facing away from the inside of the chain, the one plate of in each case two plates adjacent in the longitudinal direction in the plate string overlapping with one of its overlap regions over a correspondingly complementary overlap region of the other plate, the two plates being in each case connected together in articulated manner in a plane so as to be swivelable about a swivel axis and, to limit the swivel angle, stop projections being provided in the overlap region of the one plate and engaging in corresponding stop pockets provided in the overlap region of the other plate and embodied as depressions open to the other plate on only one side, stop faces of one stop projection interacting with mating stop faces of a stop pocket to limit the swivel angle, wherein:

• each of the two overlap regions of the one plate comprises three, in particular precisely three, stop projections formed in one piece with this plate, wherein the three stop projections have a blocking width between their stop faces with an angular dimension of the blocking width, wherein the angular dimension of the blocking width preferably amounts in each case to at least 40° (α≥40°);
• each of the two overlap regions of the other plate comprises three, in particular precisely three, stop pockets formed as depressions open on one side in this plate, wherein the three stop pockets have an opening width between their mating stop faces with an angular dimension of the opening width, wherein the angular dimension of the opening width preferably amounts in each case to at least 550 (β≥55°);
• and
• the angular dimension of the blocking width of a stop projection amounts to at least 50% of the angular dimension of the opening width of a stop pocket.

• and
• in at least one longitudinal portion of the energy guide chain, the angular dimension of the blocking width of the stop projections on the one plate, preferably on the outer plates, is selected such that these one plates, preferably outer plates, are swivelable relative to an extended position, both in one swivel direction and in an opposing, reverse swivel direction relative to the other plates, preferably inner plates, connected therewith about the respective swivel axis.
