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.

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 bellow includes an outer bellow presenting corrugations forming a plurality of valleys presenting each a valley top portion facing upwardly and connected at each end to a valley top corner forming a junction between the valley top portion and a respective bellow side. The gangway bellow further includes at least one drainage channel so that liquid accumulating into at least one of the valley top portions flows through the at least one drainage channel along the respective bellow side.

A convolute for a bellows of a gangway, the convolute comprising a first rim and a second rim arranged next to the first rim; a sheet like convolute material that extends from the first rim to the second rim; whereby in an operational position of the convolute, the convolute material takes up a trough-shaped form between the first rim and the second rim; a drainage hole is defined in the convolute material; and a closure closes the drainage hole. The convolute further comprises a drainage control band, whereby the closure forms part of the drainage control band or is attached to the drainage control band, whereby a first band point of the drainage control band is attached to or rests on a first convolute point, whereby the first convolute point is located on the first rim or on the convolute material, but closer to the first rim than to the second rim, and a second band point of the drainage control band is attached to or rests on a second convolute point, whereby the second convolute point is located on the second rim or on the convolute material, but closer to the second rim than to the first rim. The length L1 of a minimum length band path, the minimum length band path being the path with the shortest length that can be taken from the first band point to the second band point while always staying in contact with or leading through the drainage control band, is smaller than the length L2 of a minimum length convolute path, the minimum length convolute path being the path with the shortest length that can be taken from the first convolute point to the second convolute point while always staying in contact with or leading through the convolute material.
