SUBMARINE PIVOTING STRUCTURE WITH DUCTING

摘要

Submarine pivoting structure for connecting two structures in a way so as to be able to pivot in all directions includes a number of ducts in each of the structures which are mutually connected by duct parts in the pivoting structure. The pivoting structure has two pivoting arms crossing each other at a distance perpendicularly, and the ducts in the zone of each pivoting axis extend in a plane through that axis end perpendicular to the other axis so as to be positioned one to the side of the other and positioned substantially perpendicularly to that one pivoting axis. The ducts each extend as throughgoing separate structural units through both pivoting axes with short inclined connections in each duct between said axes. The ducts in the zones of the pivoting axes may comprise flexible corrugated bellows.
