Abstract: A ladder system includes a ladder, a tray, and a mode-independent attachment unit. The ladder is changeable between a step-ladder mode and a straight-ladder mode. The tray is configured to be attached to any step included in the ladder. The mode-independent attachment unit detachably couples the tray to any step.

Abstract: A foldable chair includes a front-leg unit, a seat bottom mounted on the front-leg unit for pivotable movement relative to the front-leg unit, a rear-leg unit mounted on the front-leg unit for pivotable movement relative to the front-leg unit, and mover means for driving the rear-leg unit away from the front-leg unit to establish an expanded-use mode of the foldable char and for driving the rear-leg unit towards the front-leg unit to establish a collapsed-storage mode of the foldable chair.

Abstract: A step stool includes a step frame including a plurality of legs and a handrail coupled to the step frame. The step frame is foldable so as to assume a flat profile for storage. The handrail is mounted on the step frame and is movable relative to the step frame. The handrail provides support for a user standing on the step frame.

Abstract: A foldable step stool includes an expandable step frame, steps pivotably coupled to the expandable step frame, and a fold-blocking lock coupled to one of the steps. The fold-blocking lock is operable to block pivotable movement of the steps relative to the expandable step frame when once foldable step stool has been opened.

Abstract: A load transporter includes a wheel unit and a load support coupled to the wheel unit. The wheel unit is configured to allow the load transporter to roll across a surface while the load support supports an object above the surface. The load transporter is configured to change from an upright orientation to a laid-back orientation where the load support lifts the object above the surface for transportation.

Abstract: A step stool includes an expandable tray assembly. The expandable tray assembly has a fixed tray panel and a movable tray panel coupled to the fixed tray unit for movement relative to the fixed tray unit. The movable tray panel is illustratively movable between a collapsed position, arranged above the fixed tray panel, and an expanded position, arranged adjacent to the fixed tray panel.

Abstract: A foldable table includes a table top, a table top elevator configured to support the table top above an underlying floor, and a leg motion-control unit. The table top includes a left panel and a right panel pivotably coupled together to change between an expanded position and a collapsed position. The table top elevator includes left legs pivotably coupled to the left panel of the table top and right legs pivotably coupled to the right panel of the table top. The leg motion-control unit configured to control motion of the left and right legs.

Abstract: An adjustable-height ladder includes left and right legs and a series of horizontal steps coupled to the left and right legs. The ladder also includes a utility tray.
