Device for intercommunication between coupled vehicles in which passengers can walk freely, especially railway cars or road vehicles

摘要

An intercommunication device mounted between the two oppositely-facing open ends of two coupled railway cars is constituted by a series of rings of generally rectangular shape consisting alternately of rigid rings and flexible rings suitably attached to each other so as to constitute a flexible intercommunication tunnel, the open ends of which are attached respectively to the open ends of the railway cars. The tunnel permits free and unrestricted movement of passengers from one car or vehicle to another in all types of coupled wheeled units such as railway trains, articulated road vehicles, airport passenger bridges and the like.
