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.

Line-guiding device links connect to form a loop consisting of an upper strand, a deflection region, and a lower strand. Adjacent links pivot about a pivot axis. The pivot axes are located closer to an inner side than to an outer side at least in some of the links. Each link has two side flaps opposite one another. Side flaps of adjacent links form at least one running surface on the inner side. At least some links have a roller projecting from the running surface. The upper strand and the lower strand can move via the rollers. The running surface is interrupted at least at some of the transitions between links such that part of the running surface formed by a first link has a recess and part of the running surface formed by a second link has a pin which engages in the recess, forming a gap.

A cable carrier for accommodating and guiding cables, comprising parallel first link strands of opposing first links which are connected to each other by means of first cross stays, wherein outside at least one first link strand and parallel to this a second link strand of second links is arranged, which are opposite the first links of the adjacent first link strand and of which at least some are connected by way of second cross stays to the opposite first links, and wherein, between at least some of the opposing first and second links, rollers are arranged which project beyond the first and second links on at least one side of the cable carrier perpendicular to the first and second cross stays.

A long object guiding device includes a belt-shaped unit that includes flexible and elongated tubular members. The tubular members are arranged side by side. Adjacent ones of the tubular members are coupled together so that all the tubular members are integrated. The tubular members include at least one protective tubular member. The protective tubular member is configured to accommodate a long object. The protective tubular member includes a first joint portion and a second joint portion. The first joint portion is formed to extend in a longitudinal direction of the protective tubular member. The second joint portion is formed to extend in the longitudinal direction. The second joint portion is configured to be joined to and disjoined from the first joint portion.

In a protective frame articulated body, a range of an connection angle between the protective frame body and the adjacent protective frame body is determined such that a plurality of protective frame bodies, being connected in series, through which a body to be protected is passed becomes a shape having a first bent portion, an intermediate linear portion being in a portion closer to a movable-side connection than the first bent portion, a suspending portion hanging from the movable-side connection, and a second bent portion connecting the intermediate linear portion and the suspending portion. In intermediate linear portion, a long-and-short ratio being a value obtained by dividing a long side of a smallest rectangle surrounding the protective frame body viewed from a side by a short side of the smallest rectangle is greater than or equal to a determined intermediate minimum long-and-short ratio.

Disclosed herein is an element for a cable carrier, a printing device and a method assembling a cable carrier from segments. The cable carrier element comprises a frame surrounding an opening that is to receive a cable or a tube, or a bundle of cables or tubes. The frame comprises four frame members, wherein pairs of adjacent frame members form U-shaped portions of the frame. A right-hand side U-shaped portion is adjustably engaged with a left-hand side U-shaped portion such that the respective U-shaped portions are movable relative to each other along a first direction to vary a cross-sectional area of the opening. A bottom U-shaped portion is adjustably engaged with a top U-shaped portion such that the respective U-shaped portions are movable relative to each other along a second direction perpendicular to the first direction to vary the cross-sectional area of the opening.
