Line guide made of multi-axially angle-adjustable links

1. Cable guide comprising links that are angle-adjustable multi-axially relative to each other, connected to each other in articulated fashion and arranged successively in the longitudinal direction of the cable guide, wherein each link displays an inner part with corresponding multi-axially angle-adjustable articulation connectors and a casing part for peripheral delimitation of at least one guiding duct, where the casing part encompasses at least one segment, which is connected to the inner part by a web, in a manner permitting it to be pivoted open in order to make an associated guiding duct accessible on the peripheral side, characterised in that the casing parts of adjacent links overlap in the longitudinal direction, and

in that a joint arrangement with at least two degrees of freedom is provided between the at least one segment and the web, by means of which the segment can move outwards transversely to the longitudinal direction while being pivoted open.

2. Cable guide according to claim 1 , characterised in that the joint arrangement is located on the inside in relation to the casing part.

3. Cable guide according to claim 1 , characterised in that the joint arrangement is designed as a combination of two joints, particularly as a rotary and curved guide with a curve direction lying transverse to the axis of rotation, where the axis of rotation is oriented essentially parallel to the longitudinal direction.

4. Cable guide according to claim 3 , characterised in that two claw-shaped joint brackets project on one end of the at least one segment, forming a slot-like guide for the curving movement of the rotary and curved guide, and reach in rotating fashion around corresponding joint areas, designed as journals and projecting on the web.

5. Cable guide according to claim 4 , characterised in that the slot-like guide runs essentially in the peripheral direction of the casing part and displays a constriction between the two end areas of the guide for locking in two end positions.

6. Cable guide according to claim 1 , characterised in that a snap-in projection with a snap-in hook is provided on the end of the segment lying opposite the joint arrangement, engaging the peripherally nearest web on a snap-in edge on the web.

7. Cable guide according to claim 6 , characterised in that the snap-in projection reaches into a gap between the two joint brackets of the peripherally nearest segment.

8. Cable guide according to claim 7 , characterised in that the joint arrangement, particularly each joint bracket, displays at least one outward-facing opening for detaching the segment from the web, and in that at least one projection is provided on the end of the segment lying opposite the joint arrangement for covering the opening of the peripherally nearest segment.

9. Cable guide according to claim 8 , characterised in that the opening is provided in an end area of the joint arrangement that corresponds to the opened end position.

10. Cable guide according to claim 1 , characterised in that each segment is divided into two spherical cap areas in the longitudinal direction, where the first cap area displays a centre point of the sphere that essentially coincides with the centre of a ball-and-socket type joint element on the inner part, and the second cap area can at least partially accommodate the first cap area of an adjacent link, and in that the joint arrangement, particularly the rotary and curved guide, is provided exclusively between the first cap area and the web.

11. Cable guide according to claim 10 , characterised in that the casing part of each link displays several, particularly three, identical segments, manufactured in one piece, and several, particularly three, webs are integrally moulded on the inner part in one piece in a rotationally symmetrical arrangement, particularly on the middle longitudinal section of the inner part.

12. Cable guide according to claim 11 , characterised in that the webs extend radially outwards and with one component in the longitudinal direction.

13. Cable guide according to claim 11 , characterised in that parts of the joint arrangement, particularly joint areas designed as journals, are integrally moulded on the outer end of each web, their effective length extending essentially over the entire dimension in the longitudinal direction of the first cap area.

14. Cable guide according to claim 1 , characterised in that the casing part is made up of several identical segments, each segment is preferably manufactured in one piece, and each segment can be pivoted open and is designed in such a way that, when the segments are closed, the casing parts of adjacent links reach over each other in all angled positions and essentially over the entire periphery.

15. Cable guide according to claim 1 , characterised in that the inner part of each link displays corresponding articulation connectors of the cardan or ball-and-socket joint type that are designed for multi-axially angle-adjustable connection and the absorption of tensile forces.
