ABSTRACT:
A step ladder includes a frame having a front leg and a rear leg coupled to the front leg for movement relative to the front leg between an opened position and a collapsed position. A pivot support mount of the step ladder supports a handle of the step ladder for pivotable movement on the front leg about a pivot axis. The step ladder further includes a retainer member coupled to the handle to move therewith about the pivot axis. The retainer member is arranged to lock the front leg to the rear leg when the front and rear legs are in the collapsed position. A guide of the step ladder is coupled to the pivot support mount and configured to engage the rear leg and maintain the rear leg in alignment with the front leg when the frame is in the collapsed position.
