发明名称 Cart and ladder combination
摘要 A cart and ladder combination includes a plurality of bars such that a first bar and a second bar are defined. A first coupler is adapted for releasably coupling the first and second bars together in a spaced relationship to each other. A second coupler is adapted for releasably coupling the first and second bars together in a spaced relationship to each other. A wheel assembly is removably attached to the first ends of the first and second bars. A cord member is selectively strung between the first and second bars. The second end of the first bar may be selectively attached to the first end of the second bar to form a ladder.
