Guide conduit

Guide conduit for a cable receptacle which extends between a stationary connecting point and a movable connecting point and which consists of a lower strand connectible to the stationary connecting point and an upper strand connectible to the movable connecting point, the strands being connected to each other by a redirection bow, wherein the guide conduit includes two opposite vertically fixed lateral walls with inner lateral surfaces for the contact with lateral regions of the two strands, and wherein at least one support device for supporting and guiding the upper strand is arranged on each of the opposite lateral walls and is movable between a first position in which it protrudes into the interior of the guide conduit with respect to the lateral surface and acts as a support of the upper strand, and a second position in which it does not protrude significantly over the inner lateral surface of the respective lateral wall and does not act as a support of the upper strand, and wherein the guide conduit includes a switching device in the form of a body that can be moved into the path of travel of the cable receptacle, the body being supported for pivoting on a pivot arm outside of the inner lateral surface of the respective lateral wall and being enlarged outwardly from the interior of the guide conduit on its two sides pointing in the longitudinal direction of the guide conduit and being movable by the contact of these sides with inner and outer regions of the redirection bow of the cable receptacle to a position in which it does not significantly protrude over the inner lateral surface of the respective lateral wall and in which it does not impede the continued travel of the cable receptacle, and being coupled to the support device in such a manner that the same is movable from one of the two positions to the other, characterized in that the support device is formed as a substantially flat running surface on the top side of the body and that the body is moved solely by its gravity and/or by spring force from the second position, in which the support device does not significantly protrude over the inner lateral surface of the respective lateral wall, to the first position in which the support device protrudes into the interior of the guide conduit with respect to the lateral surface, and the body in the first position extends through an opening in the respective lateral wall of the guide conduit.
