Cable duct for building electrical installation has pivoted cable cover divided into 2 partial sections between 2 relatively spaced bearing points

摘要

The cable duct has a duct element (9.1,9.2,9.3) and a duct cover (11) pivoted about 2 spaced bearing points (13,15), the part of the duct cover between the bearing points divided into 2 partial sections (11a,11b) coupled together via a linkage (19). The sum of the lengths of the 2 partial sections is greater than the relative distance between the bearing points.
