ABSTRACT

The step supports brace and stabilize retractable stairs used in recreational
vehicles, while accommodating uneven ground beneath other recreational
vehicles doorways and the various heights of the bottom stair step above the
ground. The step supports are configured to be used in one of two different
upright orientations resting atop the ground on one to two base ends of the
support. The step supports include a plurality of integral support blocks
defined and separated by two sets of vertical channels that receive the bottom
stair step for each orientation. In each orientation, the bottom stair step is
seated within one of the vertical channels and is braced between two adjacent
support blocks. The dimensions of the step support end walls and the uniformly
spaced support block allow the step supports to be selectively oriented and
positioned to brace and stabilize the stairs at incremental heights above the
ground.
