Wheeled luggage including an extendable tongue permits use as a hand-truck to transport an additional piece of luggage supported on the extended tongue. The wheeled luggage may be similar to conventional wheeled luggage, but further includes a tongue movable between an inactive and active positions. In the inactive position, the tongue is positioned within a footprint of a bottom of the luggage. In the active position, the tongue extends beyond an outer edge of a bottom of the body to provide supportive structure on which the additional luggage may be placed. The structure of the extendable tongue may have various suitable configurations. A mechanism may be provided for moving the tongue between the inactive and active positions while the user and luggage are in an upright position. An optional strap and/or strap retraction mechanism may be provided to securing the additional luggage.

1. Wheeled luggage, comprising: a rigid frame comprising a rigid upright member fixedly connected to a rigid base member;a soft luggage body supported on said frame, said luggage body cooperating with said rigid frame to provide an interior space having a fixed overall shape, said luggage body comprising at least one flexible panel and a closure operable to secure the panel to enclose said interior space for receiving objects to be carried by the luggage;a collapsible handle supported on said frame, said handle being extendable from a compact stored position to an extended operable position;a pair of wheels fixedly supported on said frame in position to rotate about a common axis to provide rolling support for said luggage;a tongue pivotably supported on said base member of said frame for pivotal movement about an axis normal to a plane of said base member, said tongue being movable between an inactive position, in which said tongue is positioned within a footprint defined by said body of said luggage, and an active position, in which said tongue extends beyond the footprint of said body to provide supportive structure on which an additional piece of luggage may be placed, said tongue being supported on at least one bushing disposed intermediate the length of tongue and dividing the tongue into a protruding portion and a stabilizing portion. 2. The wheeled luggage of claim 1, wherein said soft luggage body comprises a plurality of flexible panels, and wherein said soft luggage body defines a generally rectangular volume and comprises a bottom wall adjacent said base member, a top wall opposite said bottom wall, a back wall fixed to said top and bottom walls, a pair of opposing side walls fixed to said top, bottom and back walls, and a front wall securable to said top, bottom and side walls by said closure to define said interior space. 3. The wheeled luggage of claim 1, wherein said upright member is joined to said base member to form an angle between said base member and said upright member of approximately 90 degrees. 4. The wheeled luggage of claim 1, wherein said upright member is joined to said base member to form an acute angle between said base member and said upright member of approximately 45 to approximately 75 degrees. 5. The wheeled luggage of claim 1, wherein said tongue comprises a pair of bars, each supported on a respective bushings located eccentrically to said base member on said base member, each bushing supporting a respective one of said pair of bars for pivotal movement. 6. The wheeled luggage of claim 5, wherein each of said bars has a length greater than a distance between said bushings. 7. A piece of wheeled luggage, comprising: a rigid assembly comprising: a rigid frame comprising a rigid upright member fixedly connected to a rigid base member;a rigid handle supported on said frame, said handle being extendable from a collapsed stored position to an extended operable position;a pair of wheels fixedly supported on said frame in position to rotate about a common axis to provide rolling support for said luggage;a tongue pivotably supported on said base member of said frame for pivotal movement about an axis normal to a plane of said base member, said tongue being movable between an inactive position and an active position, said tongue being supported on a bushing disposed intermediate the length of tongue and dividing the tongue into a protruding portion extending in one direction from said bushing, and a stabilizing portion extending in an opposite direction from said bushing; anda soft luggage body supported on said frame, said luggage body cooperating with said rigid frame to provide an interior space having a fixed overall shape, said luggage body comprising a plurality of flexible panels and a closure operable to secure the panels to define said interior space for receiving objects to be carried by the luggage; wherein said body defines a footprint of said luggage, and wherein said tongue extends beyond said footprint to provide supportive structure on which an additional piece of luggage may be placed when in said active position. 8. The wheeled luggage of claim 7, wherein said tongue comprises a pair of bars, each supported on a respective bushings located eccentrically to said base member on said base member, each bushing supporting a respective one of said pair of bars for pivotal movement. 9. The wheeled luggage of claim 8, wherein each of said bars has a length greater than a distance between said bushings.
