IMPROVED COMBINATION OF A HAND TRUCK AND A LADDER
Improved combination (1) of a hand truck and a ladder, the combination comprising at least one wheel (3) and a carrier plate (4), characterized in that the combination can be easily disassembled into parts and reassembled, wherein a first part (la) comprises the ladder and a second part (lb) comprises the at least one wheel and the carrier plate. 'Easily' is understood here to mean without possibly special tools, for instance with a single manual operation and/or with the foot. After disassembly of the combination into parts the wheels and the carrier plate do not then form an obstruction during the use as ladder. The individual parts are also easier to handle, transport and store. Following disassembly of the combination into parts, the wheels are preferably movable relative to the carrier plate between a first position, in which the rotation axes are at least substantially parallel to the plate, and a second position in which the rotation axes lie at least substantially perpendicularly of the carrier plate. The wheels and the carrier plate can thus be folded together after use to form a really compact whole taking up little space, and the whole unit takes up minimal space during transport and storage.
