AMBULATORY LADDER -- ABSTRACT The typical folded ladder construction used in repairing, painting. and remodeling work must be repositioned as the work progresses. It is the purpose of this invention to provide a novel stepladder constuction with a user-powered drive. The user-powered drive is operable by a drive arm extending from the drive and accessible to a user while aboard the stepladder. By pumping action of the drive arm. the drive transmits rotational power to the base wheels on which the ladder is mounted, moving the ladder forward. A steering mechanism provided on the drive arm allows the user to direct the motion of the ladder during the pumping action. Thus, without requiring the user to dismount. the ladder may be easily repositioned by operation of the user-powered drive. A brake mechanism is provided to lock the base wheels, preventing continued rotation once the ladder has been repositioned. The ladder is designed for lightweight constuction, and may be folded and stored when not in use. By virtue of its novel design. a simple, durable, practical, and lowcost ladder may be constructed for use in many applications.
