A middle hoop system for a vehicle joint arranged between a vehicle front part and a vehicle rear part of a vehicle and forms a passage between the vehicle front part and the vehicle rear part. The middle hoop surrounds the passage. The middle hoop system comprises a cable strand which extends between the vehicle front part and the vehicle rear part, wherein the cable strand is arranged above the passage. The middle hoop system comprises a pivot lever between the middle hoop and the cable strand. A first pivot joint is formed between the pivot lever and the middle hoop. In a preferred embodiment, the pivot lever guides the cable strand at a distance from the first pivot joint. The middle hoop system is cost-effective and provides reliable guidance for the cable strand.

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 disclosure relates to a middle hoop system for a vehicle joint arranged between a first vehicle section and a second vehicle section of a multi-unit vehicle. The middle hoop system comprises a middle hoop, which is oriented in a transverse direction, and a cable strand which extends between sections of the vehicle. The middle hoop surrounds a passage intended for passengers. The cable strand is arranged above the passage. The middle hoop system comprises a guide lever which is connected to the middle hoop by means of a first pivot joint and which is connected to the cable strand by means of a second pivot joint, the axis of the first pivot joint and the axis of the second pivot joint intersecting a vertical longitudinal plane. The middle hoop system according to the invention can be produced inexpensively and offers reliable guidance for the cable strand.

Subject matter of the invention is the scissor-type frame (20) with at least one first and one second segment (22, 24), with the segments (22, 24) being connected with each other by means of a pivoting bearing (25), with the pivoting bearing (25) being divided into two pivoting bearing halves (31, 41) perpendicular to the plane of extension of the scissor-type frame, with a device (60) for detachable connection of the pivoting bearing halves (31, 41) being provided.

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.
