Abstract

See full text

The ladder includes two separate ladder elements, which are pivotable and slidable relative to each other and can also be completely separated from each other. It can be used as a step-ladder and as a leaning type ladder. The ladder element is equipped with wheels, in order to simplify the transport of the collapsed ladder. In addition, an outwardly pivotable support plate is arranged between the wheels, so that the ladder element can serve as a hand truck, whereby the bent ends of the side beams serve as hand grips. The ladder has a simple construction and can be used in many ways in household use and in commercial operations.
