Abstract: A chain link for an energy guide chain. The chain link has two link plates, and at least one pivotal transverse web, which connects the link plates together in an articulated manner and which can be converted into a closed position that connects the link plates together and into an open position that at least partly releases the link plate intermediate space. At least one pivotally designed end region of the transverse web can be secured to the link plate in a latching manner. The articulated connection between the transverse web and the link plate has a substantially cylindrical joint pin with a radius (R1) over at least one part of the circumference of the pin on one of the corresponding components consisting of the transverse web and the chain link and a substantially cylindrical pin receiving area on the other of the two corresponding components.

Abstract: A line guiding system comprising an articulated line guiding apparatus which, for guiding supply lines between two connection points that are movable relative to each other, is curved about a deflection axis extending in a transverse direction transverse to the longitudinal direction, and a separate guiding device for guiding the line guiding apparatus along at least a section of the travel path. The guiding device comprises at least one guide strand, which is arrangeable for predefining a desired course of the section of the travel path. The line guiding apparatus comprises external profile regions, which are arranged for lying against and/or on the guide strand and are shaped with a profile shape for a transversely stabilizing guiding against or on the guide strand by projecting and/or recessed interengagement of guide strand and profile shape to counteract a lateral deviation of the movable line guiding apparatus in the transverse direction.

Abstract: An energy guiding chain and side part therefore are proposed. In energy guiding chains, the pivotability of connected chain links against each other is typically limited by cooperating abutments with abutment surfaces arranged on the side parts. The invention concerns elastically deformable damping elements which dampen the abutting motion of the areas between the abutments and the abutment surfaces. In accordance with the invention, at least some abutments have a damping bow which is convexly curved in the direction of the respective other abutment surface and behind which a free space is provided, both ends of the damping bow being firmly connected to the respective abutment in the manner of an arched bridge. Furthermore, the damping bow is connected in one piece to the inner wall of the respective side part facing the inner guide channel.

The side plates have, on at least one narrow side, a corresponding fastening region for frictionally fastening a transverse connecting piece, namely a clamping receptacle which has two clamping surfaces, which are opposite one another in the longitudinal direction and between which a complementarily shaped fastening portion of the at least one separate transverse connecting piece is clamped.

Abstract: An end fastening part for an energy chain, for connecting to a link plate of a terminal chain link at one end and to a connection point on a system part at the other end. The single-piece end fastening part has a main plane and comprises: an overlapping region having a side wall for connecting to a link plate; a frame-type fastening region having a frame, in which a plurality of fastening holes is provided, for fastening to a connection point; and, therebetween, a transition region, in which a concave end face is provided. According to the invention, the end face has at least two retaining protrusions, which protrude parallel to the main plane and behind which a link plate can engage such that the link plate is retained transversely to the main plane. Furthermore, the overlapping region has at least one, preferably two fixing protrusions, which protrude from the side wall perpendicularly to the main plane, for fixing a connected link plate in position in the longitudinal direction.

Abstract: A side portion for a chain link of an energy guiding chain. The side portion has at its ends a respective overlap region which, for limiting pivotal movement, are provided with corresponding abutment surfaces and with a pivot axis, that is to say a first overlap region having first abutment surfaces and a second overlap region having second abutment surfaces. For damping of the pivotal movement, disposed in front of at least each first abutment surface is a spring lip which is resiliently deformable about a bending axis parallel to the pivot axis. The spring lip has an end region which is axial with respect to its bending axis, for coupling in the kinetic energy which is transmitted to said spring lip in the position of installation by the second abutment surface, that corresponds to the first abutment surface, of the second overlap region of the adjacent chain link.

Abstract: An opening aid for an energy guide chain with chain links. At least some of the chain links at their top side have a respective transverse leg which is arranged pivotably on a side plate and which can be fixed to the other side plate. The opening aid for guidance of the transverse legs upon opening thereof has a body extending in a working direction and a lateral extension having an inclined sliding deflection surface for the transverse legs. To simplify handling and structure of the opening aid it is proposed that the extension is mounted to the body movably relative thereto and is reciprocatingly movable between a working position in which the extension is arranged extending laterally from the body in operative guiding relationship for the transverse legs and a rest position in which the extension is arranged in inoperative guiding relationship of being moved away from the working position.
