Abstract:
A door for a door opening in a railway vehicle through which passengers may pass to gain access to the vehicle and including a set of highest to lowest steps arranged inside the vehicle, the door consisting of a single leaf and mounted to slide between a closed position substantially obstructing the door opening and an open position, and having an external face; a bridge platform mounted so as to be articulated on an axis substantially perpendicular to the door and situated substantially in a horizontal plane aligned with the highest step, said bridge platform mounted to allow the bridge platform to move between a free retracted position with respect to the said horizontal plane and a deployed position substantially lying in said horizontal plane with an outer edge of said bridge platform in substantial vertical alignment with the lowest step; and a threshold member projecting with respect to the external face of the door to extend along the outer edge of the bridge platform in the deployed position, and including means for controlling unlocking of the threshold member with respect to the door, when the bridge platform is deployed and the door opens, so that the threshold member remains in position adjacent to said outer edge of the bridge platform while said bridge platform is deployed, and further includinga) an abutment surface fixed to the vehicle; and b) a roller attached to an end of the threshold member and supported by the abutment surface while the threshold member is extended across the door opening with the door open.
