Claim 11:
12. A stair system attached to a vehicle cargo platform and movable between a deployed configuration providing access to a storage area of the cargo platform and a road-ready stowed configuration, the stair system comprising:
a mounting bracket attached to the cargo platform;
a stair assembly pivotally attached to the mounting bracket at a first pivot axis, the stair assembly comprising a first support frame comprising a first frame rail and a second frame rail, a plurality of step platforms secured between the first frame rail and the second frame rail, a first side plate attached to first frame rail and comprising a first elongated slot extending along a first length of the first side plate;
a handle assembly pivotally attached to the mounting bracket at a second pivot axis and pivotally and slidably attached to the first side plate of the first frame rail, the handle assembly comprising a first hand rail having a first lower end and a first upper end and a first handle support frame connected to the first hand rail;
a first fastener coupling the first handle support frame to the first side plate, the first fastener at least partially disposed in the first elongated slot of the first side plate;
wherein, when the stair system moves between the stowed configuration and the deployed configuration, the first fastener is operable to travel along the first elongated slot of the first side plate of the first frame rail, and both the stair assembly and the handle assembly are operable to rotate about the first fastener;
wherein, in the deployed configuration, the stair system extends outwardly and downwardly from the cargo platform, and the first upper end of the first hand rail extends over an upper side of the cargo platform; and
wherein, in the stowed configuration, the stair system does not occupy the cargo storage area and remains attached to the cargo platform.
