Abstract:
1. A ladder comprising a first frame assembly and a second frame assembly coupled to the first frame assembly for pivotable movement relative to the first frame assembly between a deployed extension-ladder mode and a deployed step-ladder mode, each frame assembly including a pair of frame members having a plurality of rungs interconnecting the frame members, a platform including a platform step and means for detachably mounting the platform step on two rungs of the ladder, a level adjuster to selectively adjust a position of the platform step to maintain the platform step in an essentially level position relative to a surface upon which the ladder is deployed in either of the two deployed modes, and wherein the means for detachably mounting the platform step includes a hanger bar and a cross bar coupled to a first end of the hanger bar and mounted on the platform step, and further wherein the level adjuster includes a slider, a base and an elongated slot associated with both the slider and the base and configured to matingly receive the cross bar for rotational movement relative to the platform step and for vertical movement therein, and the slider is configured to allow the cross bar to move within the elongated slot in a first position of the slider and the slider and the base cooperate to lock the cross bar in the elongated slot in a second position of the slider.
