    摘要： In the illustrative embodiments disclosed, a folding portable multiple-purpose work unit is interchangeably useable in three main work modes: as a stepladder, as a step stool, and as a small workbench having a vise. The substructure of the unit includes front and rear leg frames, the front frame having two steps, and is foldable to allow ready storage of the unit. The vise unit forms the top of the substructure. A seat member covers the vise unit when the work unit is in the step stool and stepladder modes and pivots to uncover the vise unit in the workbench mode. When so pivoted off the vise unit, the seat member forms a tool tray which also blocks use of the work unit as a stool or ladder while the seat is not in place. The work unit also includes a handrail which is movable between a raised position in the stepladder mode, where it affords support to a user standing on the steps or seat of the unit, and a lowered position in the workbench or step stool mode, where it is out of the user's way and also facilitates storage of the unit. The substructure of the work unit is latched in the erect position by a pair of hooks carried by a latching rod, the hooks engaging with abutment surfaces on abutment blocks connected to the upper ends of the legs of the substructure. The latching rod carries a release member in its central region which, when the seat is in position, can be rotated and lifted to cause release of the latching mechanism and automatic folding of the substructure.

    摘要： A vanity storing step utilizes an L shaped plate, one leg of which is secured to the interior floor portion of a vanity carrying a sink, the other leg of which extends upwardly towards the base of the sink. A pair of plates are secured extending transverse to the upwardly extending leg having the uppermost edge adjacent to the floor of the sink, carrying a pair of pivot rods therein. The pivot rods are secured to a pair of beams to which are attached a pair of legs and a stair tread straddling the beams. When not in use, the stair tread is pivoted upwardly and inwardly below the sink floor to a stored position within the vanity carrying the sink. In a use position, the legs have their lowermost portions reside on the floor in front of the cabinet such that the stair tread is disposed in a horizontal position above the floor and adjacent the front of the vanity, thereby providing convenient elevation for children utilizing the sink.

    摘要： A foldable step stool adapted to be affixed to an upright surface for providing access to a height above the stool comprises a first member adapted to be affixed to an upright surface. A second member is hingedly affixed to the upright surface and is movable from a position substantially coplanar with the first member to a position at substantially right angles to the first member. A third member is hingedly affixed to the second member and is movable from a position substantially perpendicular to the second member to a position substantially parallel to the second member.

    摘要： A step stool structure having an elongate base with a flat top and a peripheral wall and a floor-engaging member at the bottom of said wall to resist movement when engaging the floor. The base has a plurality of collapsible rollers for rollably supporting the base and step structure under no load conditions and collapsible under the application of relatively slight pressure to the structure to allow said floor-engaging member to engage the floor. An upstanding support on the base member having a platform serving as a seat or step, said base and upstanding structure having multiple steps with the platform being the top step. Supports extending upwardly from the platform are removably mounted on the structure and adapted to be engaged by portions of a person on the structure. A form of the support being elongate posts to be grasped by a person. A shelf may be mounted on the upper portion of two such posts for holding articles.
