发明名称 Step ladder/chair combination
摘要 A step ladder/chair combination comprises a first and second spaced apart step and seat platforms which are supported from a first pair of parallel legs pivotally interconnected to the platform and a second pair of parallel legs are pivoted to the seat. The second legs include lower ends or feet which are movable outwardly away from the feet on the first pair of legs to an expanded condition wherein the step ladder/chair assumes a self-supporting, standing position on a floor or other surface ready for use. The step ladder/chair also includes a third pair of parallel legs which are parallel to the first legs and extend upwardly above the chair platform to support a back rest. The third legs are pivotally connected to the step and seat platforms. Short linkages are provided to pivotally interconnect the second and third legs and thereby limit the relative pivotal movement of the second legs relative to the first legs so that the step ladder/chair may be maintained in a collapsed or folded position for storage and the like occupying a minimum space or when pivoted outwardly to an expanded or self-supporting standing position may be used as a seat or a step ladder.
