Abstract:
A vehicle having a compactable walkway, including a supporting surface and a plurality of steps, pivotally coupled to the supporting surface, oriented, spaced, and positioned to provide a graduated walkway when in a deployed position and to lie substantially parallel to the supporting surface when in a retracted position. There is also a support member coupled to a distal end of each of the plurality of steps to enforce consistency of position of the plurality of steps between the deployed and retracted positions; a railing coupled to the support member; a motivator coupled to one of the plurality of steps and configured to direct the plurality of steps from the retracted position to the deployed position; a vertical support coupled to the vehicle for bracing; and a shell coupled to the railing for covering when plurality of steps are in the retracted position.
