Abstract:
1. A vehicle staircase device comprising: a first lower platform having a first length and a first width, the first lower platform having a hitch connector adapted to connect to a vehicle, the first lower platform having a first edge and a second edge spaced apart by the first length; a second platform, spaced vertically apart from and above the first lower platform, having a second length and a second width, wherein the first lower platform and the second platform are substantially parallel, the second length being less than the first length and the second width is greater than the first width; a staircase structure connecting the first lower platform and the second platform, the staircase structure comprising at least a first stair structure located a first height orthogonal to the first lower platform and having a stair structure width substantially equal to the first width, the first stair structure being oriented such that a stair structure length is parallel to the first length and the stair structure length overlaps at least a portion of the first length and the first stair structure originates at a distance measured parallel to the first length and originating from either the first edge or the second edge; an extension section having a third length and a third width, the third width being substantially equal to the difference between the first width and the second width, the extension section connected to the second platform, with the second length and third length together being substantially equal to the first length.
