Abstract: A gangway floor for a gangway between a first car of a multi-car vehicle and a second car of said vehicle comprises a first floor panel and a second floor panel, wherein the first floor panel is arranged to rotate about a first axis that does not lie in the plane that the first floor panel lies in, and the second floor panel is arranged to rotate about a second axis that does not lie in the plane that the second floor panel lies in, wherein the first axis is different from the second axis.

Abstract: An inner wall lining of the bellows of a connection between two hinge-linked vehicles or vehicle parts is provided, the inner wall lining including several wall elements that are disposed within the connection so as to be slidabic relative to each other via a guide device, the guide device including at least one guide arn that is disposed on the one wall element and is oriented parallel to and at a distance of said wall element, the guide arm slidably receiving the other wall element, the distance between the one wall element and the guide arm corresponding approximately to the thickness of the other wall element.

Abstract: A revetment made wholly or predominantly from concrete, useful to line a stream bed, having upper and lower surfaces, and having upstream and downstream edges, has, for each upstream edge, an upstream bevel, which intersects the upper surface and which intersects said upstream edge. The revetment has an array of holes extending between the upper and lower surfaces. Each hole has a lateral wall flaring outwardly in a downstream direction from a circular mouth at the lower wall to an elongate mouth at the upper wall. Each upstream or downstream edge is stepped so as to define an upper or lower flange. In an assembly of such revetments, which may be connected to one another, as by cables, each of at least some of the upper flanges overlies one of the lower flanges.

Abstract: The subdivided bellows of a connecting element is provided between two articulated vehicle components. The halves of the bellows are coupled at their ends to a vehicle component, and a middle frame (1) has a device for guiding supply lines (100), e.g. tubes, cables, etc., in a ceiling area of the connecting element which is movable relative to the middle frame (1).

Abstract: The inner covering for the connecting corridors between cars of rail vehicles consists in each case of side wings, each of which consists of at least two independent frames (1, 2, 3) the spars of which are pivoted to each other at the corners, the frames being held in bottom and top telescopic guide rails (4). When the outermost vertical frame spars are fastened by hinges (8) to the car body or coupling frame, the inner covering can follow all movements which occur.

Abstract: 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.

Abstract: A gangway construction for vehicles comprises divided hood structures each of which has a first end and second end, the first ends of the respective hood structures being fixed to the vehicles, and the second ends thereof being made free and to face each other, a plurality of hood pressers provided between upper sides of metal frames on a free side of the hood structure and the vehicles and between lower sides thereof and the vehicles for urging the hood structures in their extension direction upon coupling operation, the plurality of hood pressers being arranged in a horizontal plane in convergent relation, and positioning members for guiding and engaging each other upon mutual approach of the members to effect a centering action, the positioning members being provided in the release side metal frames.

Abstract: A hood device for coupling cars comprises a first hood component having one end secured to one of a pair of car bodies to be coupled with each other and a second hood component having one end secured to the other car body and the other end adapted to be coupled with the other end of the first hood component, each of the hood components having side wall panels provided on both side portions thereof. Each side wall panels includes a fixed side wall panel having one end secured to the other end of the associated hood component, and a movable side wall panel having one end mounted on the associated car body and adapted to be turnable about a substantially vertical axis and the other end resiliently urged such as to be directed to the inner surface of the adjacent fixed side wall panel.

Abstract: A tunnel structure for interconnecting passenger compartments on an articulated vehicle includes pairs of cylindrical walls which overlap during steering movement of the vehicle. To seal between the cylindrical walls, a pair of inner walls is provided which include hinged flaps lying against the cylindrical wall. The flaps are hinged on an inclined axis to reduce clearance between the cylindrical walls and the side walls upon the vehicle negotiating vertical curves.

Abstract: A vestibule connection for the adjoining ends of two cars of a rapid-transit vehicle includes an apron which is maintained centered in the space between turntables at the adjoining ends, by being mounted on two transverse parallel shafts via telescopable units that are pivoted to these shafts and alternate ones of which, as considered in direction lengthwise of the shafts, exert a biasing action on the apron in mutually opposite directions along the centerline of the two cars.
