Abstract
A step stool or ladder includes a latch that engages a cross member to prevent a step from disengaging from the cross member. The curved end of the latch has a tail that provides additional weight to the end of the latch that engages the cross member and allows for decreased tolerances in manufacturing the latch. The other end of the latch has a knob that extends through an opening in the step so that the latch is accessible and to give visual cues to the user. The knob also maintains the latch in its position in the opening in the step. A bent out portion of the latch midsection serves to limit the amount of travel between the knob and the bent portion. The latch rotates on the portion of the latch between the bent portion and travel limiter and the knob attached to the latch.
