Abstract:

A step stool includes an inner frame, an outer frame, an actuator, and a coupler. The inner frame includes two inner pillars, and the outer frame includes two outer pillars attached to a platform near opposite ends of the platform and configured to receive the two inner pillars. The actuator is coupled to one of the two inner pillars and one of the two outer pillars, and is operable to raise the outer frame relative to the inner frame. The coupler couples the two outer pillars to each other to evenly lift the opposite ends of the platform when the actuator raises the outer frame.
