ABSTRACT:
A novel extendable-retractable stairs apparatus which provides stairwise access to the top of a vehicle. The apparatus mounts to the exterior of a vehicle and retracts into a self-contained package for travel. When unpacked for use, one part of the package cover rotates downward to become the bottom step. The stairs extend upward, parallel the side of the vehicle on which the apparatus is mounted. The top stair attaches to a support affixed to the vehicle for stability. Grab bars can be mounted to the vehicle to assist the user to maintain balance while using the stairs.
