Abstract
A table is provided with a single retractable caster to facilitate manually transporting the table from one location to another. The retractable caster is located substantially directly below the center of gravity of the table, so that when the caster is extended to an "on" position, the table can be held in a generally poised condition over the caster wheel, and manually rolled across the floor. A pedestal-type base, having radially outwardly extending feet with glides provides outrigger support for the table during transport. The caster is shifted between the extended "on" position, and a retracted "off" position by simply tilting the table slightly about its base, such that a person having ordinary strength and dexterity can easily and safely move the table about a room without assistance. An institutional version of the table is designed for use in hospitals, nursing homes, and the like, and may include a vertically adjustable top to accommodate both ambulatory and wheelchair patients, as well as a raised, marginal, top edge that forms a spill guard with contrasting colors to facilitate use by the visually impaired.
