摘要： The present invention is for a step stool to be used by a child, diminutive person or an adult of average height to gain vertical reach. The retractable step stool/access device is positioned by one's foot between an elevated, retracted position or a lowered, deployed step accessible position. Internal stored energy mechanisms can be employed to ease some of the physical effort required, especially by a child or diminutive person, to complete the deployment/retraction cycle with either of their feet. In the raised, retracted position, the step stool is elevated from contact with the floor and clear of the standing area for general usage and allowing access for cleaning and maintenance of the floor.

摘要： A retractable step stool assembly for assisting a person in elevating him or herself above a floor includes a base member, a step stool member which in an upright position has a generally horizontal platform surface and two side members which depend downwardly from opposite ends of the platform surface, and an arm assembly which is configured to pivotally connect the step stool member to the base member for movement of the step stool member between a stored position in which the step stool member is positioned over the base member to a deployed position in which the step stool member is positioned on the floor in front of the base member. The arm assembly is configured such that the platform surface remains generally horizontal during movement of the step stool member between the stored position and the deployed position. The step stool member includes an upwardly directed foot-engaging member which is engageable by the bottom of the person's foot and is configured to transfer at least an initial downwardly directed force from the person's foot into movement of the step stool member from the stored position toward the deployed position. In this manner, the person can move the step stool member from the stored position to the deployed position by engaging the foot-engaging member with only his or her foot.
