ABSTRACT:
An article of wheeled luggage having improved mobility characteristics employs a wheeled pivotable leg operatively coupled to a retractable and extendable handle. The article becomes self-supported in a forwardly-tilted configuration when the user tilts the article and causes the wheeled pivotable leg to swing outwardly from the forward surface of the article. Stable support in the tilted position is provided by at least one rolling member on the bottom surface of the article proximate a forward surface thereof and by at least one rolling member on the base of the pivotable leg. In the tilted configuration, the article has a lower center of gravity and a larger wheelbase or footprint than when the article is standing upright, and is better able to counteract overturning forces.
