Abstract

In a cable routing device having a cable carrier and a guiding device for the cable carrier, wherein the cable carrier has a first strand connected to a first connector and a second strand connected to a second connector, which are connected to one another via a rerouting area, and the guiding device having a contact area for the stationary contact of at least one part of one of the strand is provided for a secure contact of the corresponding part of the strand with the contact area and for preventing sliding friction, the cable carrier having at least one magnet, and the contact area having a ferromagnetic or ferrimagnetic material, wherein the magnet interacts with the contact area in a predetermined positioning area of the cable carrier relative to the guiding device such that the strand having the magnet adheres to the contact area with a predetermined magnetic attractive force.

First claim

What is claimed is:

a line carrier for receiving and guiding lines between a first connection and a second connection which are moveable relative to each other, and
a guiding device for the line carrier,
wherein the line carrier has a first run connected to the first connection and a second run connected to the second connection, which runs are connected together by a direction-changing region,
wherein the guiding device has at least one contact region for stationary contact of at least a part of one of the runs,
wherein the line carrier has at least one magnet and the contact region for stationary contact of at least a part of one of the runs has a ferromagnetic or ferrimagnetic material,
wherein in a predetermined positional region of the line carrier in relation to the guiding device the at least one magnet cooperates with the contact region such that the run having the magnet adheres to the contact region with a predetermined magnetic attraction force, and
wherein the at least one magnet is a plastic-bonded permanent magnet.

2. The line guide device as set forth in claim 1 , wherein the at least one magnet is releasably fixed to the line carrier.

3. The line guide device as set forth in claim 1 , wherein the line carrier has a longitudinal direction, and at equidistant regions in the longitudinal direction the line carrier has at least one respective magnet.

4. The line guide device as set forth in claim 1 , wherein the guiding device has a contact region with ferromagnetic or ferrimagnetic exclusively for one of the runs.

5. The line guide device as set forth in claim 1 , wherein for each of the two runs the guiding device has a contact region with ferromagnetic or ferrimagnetic material.

6. The line guide device as set forth in claim 1 , wherein the contact region has a flat contact surface opposite to the line carrier.

7. The line guide device as set forth in claim 1 , wherein the contact region of the guiding device, that has the ferromagnetic or ferrimagnetic material, is in the form of a flat plate which extends over the length at maximum extension upon displacement of the line carrier of the run having the at least one magnet.

8. The line guide device as set forth in claim 1 , wherein at its contact surface which faces towards the line carrier and comes into contact therewith, the contact region having the ferromagnetic or ferrimagnetic material has a layer of non-magnetizable material, which covers over the ferromagnetic or ferrimagnetic material.

9. The line guide device as set forth in claim 1 , wherein a contact region of the guiding device is coupled to a drive for displacement of the line carrier and entrains the run in question by the magnetic attraction force between the at least one magnet and the contact region.

10. A line guide device comprising:
a line carrier for receiving and guiding lines between a first connection and a second connection which are moveable relative to each other, and
a guiding device for the line carrier,
wherein the line carrier has a first run connected to the first connection and a second run connected to the second connection, which runs are connected together by a direction-changing region,
