Abstract
A step stool has a top step that is foldable alongside a next lower step to form a large platform. The platform stool has a pair of hinged frame assemblies that are laterally spaced apart to embrace a plurality of uniformly ascending elevated steps disposed therebetween. A first step and a second step situated above the first step are journaled for pivotal movement to the frame assemblies. A pair of laterally spaced-apart step linkages support the first and second elevated steps. A third elevated step is supported between the frame assemblies. A pair of laterally spaced-apart platform linkages support the third elevated step in either a top position above the second step or a lower position alongside the second step. A pair of platform brackets can be mounted on the rear legs substantially adjacent to the second elevated step. The stool can further include a pair of latch assemblies. Receptacles can be provided in the frame assembly hinges and platform brackets to receive each latch assembly so that the third step is lockable in either the top or lower position. The fully extended platform stool is collapsible to permit the steps to fold flat within the folded frame assemblies.
