  • Patent number: 4828208
    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.
