20120090934	LUGGAGE - An article of luggage comprises a suitcase with a substantially cuboid fabric structure supported by a frame. A set of wheels and an upward and rearward projecting handle are mounted on the frame. The suitcase is stable in an upright position. A user may incline the handle of the suitcase rearward from the upright position to wheel the suitcase. Thus, the suitcase need not be orientated far from the vertical when being wheeled by a user. The handle may be fixed but is preferably telescopic. The frame has a plurality of elongate members connected to form a frame base and a frame top spaced apart by diagonal length members connected between the front of the base and the rear of the top. The handle is mounted to the diagonal length members and the wheels are mounted to the frame base.	04-19-2012
