Abstract
A step stool having a front frame member having a bottom end and a rear frame member having a bottom end, the front and rear frame members being coupled together for movement between an opened position in which a bottom end of the front frame member is spaced apart from the bottom end of the rear frame member and a collapsed position in which the bottom ends of the front and rear frame members are positioned to lie adjacent to one another, a step being pivotably coupled to the front frame member for movement between a use position in which the step is oriented at a first angle relative to the front frame member and a storage position in which the step is oriented at a second angle relative to the front frame member, and a generally S-shaped guide track coupled to the step and a follower coupled to the rear frame member to engage the guide track, the follower being arranged for movement along the guide track in curvilinear fashion following the S-shape as the rear frame member moves along the front frame member, and movement of the follower relative to the guide track moves the step between the use and storage positions.
