A gangway for connecting a first car with a second car and for allowing passage of passengers from the first car to the second car. The gangway includes a first hoop having a straight line section for at least a portion of its circumference and a second hoop. A connection element is connected to the first hoop and to the second hoop. The connection element includes an elongated free surface that is movable relative to the straight line section of the first hoop.

The invention relates to a cover between at least two vehicle parts of the type connected to one another in an articulated manner to form a vehicle e.g. a streetcar or an articulated bus, the cover comprising an at least U-shaped cover that is elastically yielding, the U-shaped cover bridging a space between the two vehicle parts, wherein the U-shaped cover being double-walled, with an outer wall and an inner wall being formed in one part.

A gangway between two articulately connected vehicles includes at least one bellows enveloping a gangway system to form a tunnel. The bellows has several tunnel-shaped circumferential bellows frames for forming corrugations or folds. The bellows has spacers, in the floor or roof area. The spacers are disposed between individual bellows frames and between a bellows frame and a fixed point connected to the respective vehicle.

Described is a device for connecting between the bellows and the frame of articulated vehicles, including a connecting element having a hooking portion which can be coupled to an end edge of a bellows, and an engagement portion which can be inserted in a compartment defined by a rigid support of the frame of the vehicle and abutting at least one first inner wall of the compartment; the device also has an elastically deformable insertion element, also positioned in the compartment between the connecting element and a second inner wall, for stably engaging the engagement portion against said first inner wall. The insertion element and the connecting element comprise reciprocal coupling means configured for making a mutual connection between the insertion element and the connecting element.

A gangway assembly comprising a gangway for arrangement between two cars of a multi-car vehicle having a first bellows with a frame for connecting to a counter frame of a second bellows of the gangway, a first electrical coupler connected to the frame of the first bellows and a second electrical coupler connected to the counter frame of the second bellows. A first support is connected to the frame of the first bellows. The first electrical coupler is movably mounted on the first support so as to be movable between an advanced position and a retracted position. A second support is fixedly connected to the second bellows counter frame, the second electrical coupler movably mounted on the second support and movable between an advanced position and a retracted position. An advancing mechanism advances the first and second electrical couplers from their respective retracted position to their respective advanced position.

A gangway for a multi-car vehicle has a bellows attached to an endframe and a crimping element attached to the endframe. The crimping element has a crimping mouth. A part of the bellows is inserted into and held inside the crimping mouth. The crimping mouth is defined by two sidewalls arranged next to each other and joined together at one of their ends by a bottom wall, and not joined together at opposite ends to provide an opening of the crimping mouth. The crimping mouth causes the part of the bellows that is held inside the crimping mouth to be pinched together, and is of a material having spring properties such that one of the side walls can be moved away from the other one of the side walls only by tensioning the side walls against a restoring force provided by the spring properties of the crimping element.

A bellows, as gangway protection for a transitional bridge between two movably connected wagon bodies of a multi-part vehicle or between two movably connected portions of a passenger bridge or passenger stairs, has a roof and two side walls arranged opposite one another. The two side walls or the roof or a connecting region between one of the two side walls and the roof each have a plurality of folds or corrugations. The plurality of folds or corrugations include at least a first blank and a second blank connected to the first blank made of a flexible sheet material, and the first blank and the second blank are at least partially materially bonded to one another.

The invention relates to a cornerpiece (3) of a convolute (2) of a bellows (1) of a gangway, the cornerpiece (3) extending from a first end (7) intended to be connected to a further part of the convolute (2) to a second end (8) intended to either be connected to a further part of the convolute (2) or to serve as an end of the convolute, wherein the cornerpiece (3) at least for a part of its extend from the first end (7) to the second end (8) has the shape of a trough that is bent into an arc, wherein the trough has a bottom line (9) or a bottom area (18), wherein the cornerpiece (3) has a first piece (10) that is a cutaway from sheet material and has a second piece (11) that is a cutaway from sheet material, wherein the first piece (10) is joined to the second piece (11) along a line of connection (12), wherein the line of connection crosses the bottom line or the bottom area.

A treadplate for a floor of a gangway the treadplate having a basic body of a first material, and a plurality of bones of a second material, wherein the bones are encapsulated by the first material, wherein the second material has a higher elastic modulus than the first material and/or the stiffness of at least one bone of the several bones is higher than the stiffness of the basic body.
