Abstract
A foldable pontoon composed of two inner floating bodies and two outer bodies which are each connected to one another by joints and can be folded together in the form of a W in the transport position. The floating bodies are connected to each other by a pull rope device composed of pull ropes and levers for facilitating the folding and unfolding procedures, wherein a two-arm unfolding lever mounted at each end face of the outer floating bodies acts with one end at a stop and a pull rope is attached to the opposite end of the unfolding lever. The joint connection between the outer floating body and the inner floating body is constructed as a double joint with a joint shaft each connected to the outer floating body and to the inner floating body. The unfolding lever is constructed as a joint plate for effecting an articulated connection of the joint shafts. The unfolding levers arranged at the end faces of the pontoon are connected to each other so as to move together.
