Abstract: A ladder. A step is coupled to a primary leg, an adjustable base is coupled to the primary leg, the adjustable base includes a first base section rotatably coupled to a second base section and the second base section is coupled to the primary leg. An adjuster retains the first base section at one of a plurality of rotations with respect to the second base section. In implementations a secondary leg is coupled to the primary leg proximate a top of the ladder and a movable section is coupled to the primary leg with an arm and further coupled to the secondary leg with an arm, the movable section having a substantially planar upper surface configured to generally face the top of the ladder when the ladder is in an open configuration and configured to generally face the top of the ladder when the ladder is in a closed configuration.

Abstract: A ladder comprises a top step, two leg assemblies mounted to the top step, and a step assembly mounted to the top step. The leg assembly and the step assembly pivot from a closed position in which the leg assemblies and the step assembly are extend vertically downward from the top step to an angular position in which the leg assemblies and the step assembly are angularly displaced from vertical and oriented along radial axes positioned 120 degrees from one another in a tripod configuration. Each leg assembly and the step assembly are locked to the selected angular position. The length of each leg assembly can be adjusted as desired. The step assembly includes a plurality of steps. Each of the leg assemblies and the step assembly have a foot for engaging the ground.
