ABSTRACT:
An intermediate portal protecting an intercommunicating gangway between two coupled vehicles, particularly railroad cars. The portal comprises two mirror-symmetrical parts which are detachably connected to each other. The portal is closed on all sides and mounted for lateral displacement relative to the cars. On a straight track, the portal contour is flush with the contour of the cars. The parting surfaces between the portal and the respective car are designed to maintain a definite narrow gap therebetween under any operating conditions, as long as a supporting and guiding structure can follow these parting surfaces in parallel motion. To this end, the invention provides a supporting and guiding arm by which the portal is guided both horizontally and vertically by means of cam tracks conformable to the parting surfaces which are preferably spherical.
