Patent ID: 7437052

Claim:
In a machine with a movable machine part a line combination is provided comprising: (a) at least two parallel flexible power-carrying lines for connecting a connector fixed in place or fixed on the machine with the movable machine part, each of said at least two parallel flexible lines having a respective length; (b) at least two flexible hoses, each of said lines being disposed in a respective one of said flexible hoses: and (c) a plurality of T-shaped connecting elements formed onto said at least two flexible hoses, each connecting element comprising a T-groove or a corresponding T-shaped projection extending over the entire length of the line disposed in the flexible hose so that the T-shaped projection and the T-groove of adjacent flexible hoses engage into one another with shape fit and are displaceable relative to one another in a longitudinal direction to permit the hoses to be displaced axially relative to one another in the line combination, wherein the line combination is able to follow almost any desired movements of a movable machine part, and performs a non-twisted guidance of the lines while doing so.
