Abstract: A chain link for an energy transmission chain, comprising two mutually spaced side plates which are interconnected by means of two crosspieces, delimit an interior for guiding cables and each have inner faces facing the interior. A frame module is provided and is mounted between the crosspieces, borders a portion of the interior and delimits at least one guide chamber for the purpose of internal subdivision. The frame module has two lateral walls and two transverse regions extending transversely thereto, wherein each transverse region covers part of the inner face of a crosspiece and forms a cable-protecting support face.

Abstract: A line guide device comprising an envelope for supply lines and an articulated support chain. One chain link has an inside projection in a first longitudinal portion and an inside cross-bridge with an extended stop face and a recess adjoining the cross-bridge in a second longitudinal portion. In the extended position, the projection of one chain link engages in the recess of the following chain link and on the cross-bridge thereof. A support chain, in which each chain link has, in its second longitudinal portion, an outside cross-connection which in the arcuate position interacts with an outside arc stop face of the first longitudinal portion and has an inside cross-connection which in the extended position interacts with an inside extended stop face of the first longitudinal portion.

Abstract: A line guide device comprising a displaceable flexible envelope with duct-like sheaths for lines and end fastening devices in each case comprising two clamping plates with major faces for exerting a clamping force and within each case a retaining portion for strain relief elements. The retaining portion retains the strain relief elements on the respective clamping plate against displacement in the longitudinal direction and, according to the invention, forms a profile cross-section with undercut. The strain relief elements each have at least one connection portion which, for form-fitting engagement behind the undercut, corresponds to the profile cross-section of the retaining portion in order also to retain the strain relief element on the clamping plate in the direction perpendicular to the major face.
