- the sections are not necessarily telescopic.
- the sections are, in the working position, in axial extension of one another, juxtaposed at their connection end and secured in this position by any intermediate removable holding means connecting the connection ends of the two sections, such as a dowel if one of the sections has a partial overlap area of the other section, or an elastic open sleeve or a collar suitable for covering the connection ends of the two sections.
- the guide end of each section is associated with a transmission element (pinion, bearing, etc.) opposite by a link adapted to make the section and said transmission element integral in rotation about the transverse axis, and allow the pivoting of the section around at least one axis perpendicular to the transverse axis.
- connection is for example a pivot or constant velocity connection (universal joint).
- the coupling ends initially held by the intermediate removable holding means are dissociated, and the said sections are made to undergo pivoting about an axis perpendicular to the transverse axis.
- the connection end of each section is then free.
- This embodiment is particularly suitable for any rolling member with
