摘要： A multi-position ladder includes a ladder, a longitudinally extending support member for supporting the ladder, and a connecting member connecting the support member and the ladder. The connecting member includes a sliding bar, a pivot bar, and a rotating arm, the sliding bar being in sliding engagement with the support member for permitting lateral shifting movement of the ladder along the support member to one of multiple generally vertical use positions, the pivot bar extending laterally outwardly from the sliding bar for permitting pivotable movement of the ladder about the pivot bar between a generally vertical use position and one of multiple storage positions, and the rotating arm providing tilting movement of the ladder towards or away from a wall to which the support member is attached.

摘要： A multi-position ladder includes a ladder, a longitudinally extending support member for supporting the ladder, and a tightening mechanism associated with the ladder or the support member. The tightening mechanism is operable to secure the ladder to the support member, thereby prohibiting movement of the ladder along the support member.

摘要： A multi-position ladder includes a ladder, a longitudinally extending support member for supporting the ladder, and a connecting member connecting the support member and the ladder. The connecting member includes a sliding bar, a pivot bar, and a rotating arm, the sliding bar being in sliding engagement with the support member for permitting lateral shifting movement of the ladder along the support member to one of multiple generally vertical use positions, the pivot bar extending laterally outwardly from the sliding bar for permitting pivotable movement of the ladder about the pivot bar between a generally vertical use position and one of multiple storage positions, and the rotating arm providing tilting movement of the ladder towards or away from a wall to which the support member is attached. The ends of the rotating arm are slidably received in elongated slots in the uprights of the ladder for permitting sliding movement of the ladder relative to the rotating arm. A locking assembly permits selective securing of the free end of the ladder to the support member in a storage position.
