ADJUSTABLE STAIRWAY HAVING RETRACTABLE WHEEL CARRIAGE ABSTRACT An adjustable stairway is disclosed that is supported on a retractable, wheel mounted carriage. A locking mechanism selectively maintains the carriage in a lowered, ground engaging position for easy maneuvering of the stairway. The weight of the stairway urges the carriage into a raised position when the locking mechanism is released, allowing the stairway to rest on stationary foot pads.
