机译:梯级装置

摘要

A ladder levelling apparatus includes a ladder having a pair of side rails in spaced relation with a cross member extending the pair of side rails, a bracket affixed to the cross member, and a bar slidably received within the bracket so as to have ends of the bar respectively extending outwardly beyond the pair of side rails. A first foot and a second foot are respectively affixed to the ends of the bar. The bar is arch-shaped such that the ends are positioned below the bottom of the pair of side rails when the bar is centered relative to the side rails. A receptacle extends from the bracket suitable for receiving the bar therein.
