Abstract

The invention concerns a line guide device (100 . . . 1100) for lines like for example cables, hoses or the like, in particular for a clean room application, which has a flexible sheath (210 . . . 610). The sheath (210 . . . 1100) is designed in the manner of a corrugated tube and has a corrugated profile for the purposes of flexibility. The sheath (210 . . . 1100) has an asymmetric bending characteristic in relation to curvature about the direction-changing axis and to opposite curvature such that the permitted bending sag is considerably less than the desired curvature. According to an aspect there is proposed a particular configuration of shell portions (331, 332; 1031, 1032; 1201, 1202) for constructing the sheath, in particular in respect of the corrugated profiles and the fixing of the shell portions (1201, 1202). A further aspect concerns a supporting skeleton (440; 540; 640; 940) for a corrugated tube.

Claims16

Dependent claims

A line guide device for lines for a clean room application, wherein the line guide device comprises:

a first end for fixing to a stationary connecting location and a second end for fixing to a relatively moveable connecting location and between the ends forms an upper run, a displaceable direction-changing curve and a lower run,
wherein the direction-changing curve is curved about a direction-changing axis, and wherein the line guide device has a flexible sheath and the sheath dust-tightly surrounds an internal space,
wherein the sheath is configured as a corrugated tubular sheath and has a corrugated profile which serves for flexibility,
wherein the sheath at least in a longitudinal section has an asymmetric bending behaviour in relation to curvature about the direction-changing axis and to opposite curvature such that a permitted bending sag is less in comparison with a desired curvature, wherein the corrugated tubular sheath has a different corrugated profile at an outside of its periphery than at an inside of its periphery, that faces towards the direction-changing axis,
wherein the corrugated tubular sheath in a longitudinal section is composed portion-wise of two shell portions with different corrugated profiles and wherein each of the shell portions has two longitudinal sides, and at both of the longitudinal sides, a fixing band extending in the longitudinal direction.
