Patent abstract
A rolling bag adaptable for ascending and descending a staircase safely as well as for level and incline rolling. A handle selectively tilts to an angle that provides maximum leverage for ascent and descent of the bag on a staircase. The handle has a locking device that sets the desired tilt angle. The rolling bag has a recessed conveyor at the rear that has a track that selectively loosens when adapting to a staircase by increasing distance the conveyor rolls, the track conforming to a tread and a riser of a staircase. The conveyor has an offset device that selectively adjusts the track tension, the offset device coupled to handle so that when the handle tilts the track tension is loosened.
