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.

A ladder comprising:
- a top step,
- two leg assemblies mounted to the top step, each leg assembly having means for adjusting the length thereof and a foot,
- a step assembly mounted to the top step, the step assembly having a plurality of steps and a foot,
- the step assembly foot and the two leg assembly feet forming a tripod configuration whereby the ladder rests upon said three feet,
- means for pivoting the leg assembly and the step assembly 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 the tripod configuration, and
- means for locking each leg assembly and the step assembly to an angular position along the radial axes positioned 120 degrees from one another.
