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 ...

1. A rolling bag configured for ascending and descending a staircase, comprising: a tilting handle, said handle configured for tilting into a plurality of angles, a first angle configured for ascending a staircase, a second angle for descending the staircase and a third angle for rolling on a plurality of bottom wheels, said handle retracting and extending to a plurality of lengths, a first length for ascending the staircase, a second length for descending the staircase and a third length for rolling;a conveyor belt, having a continuous track, said track driven by a plurality of rollers; andan offset device, said offset device coupled to the bottom of the tilting handle, the offset device selectively engaging the rollers of the conveyor belt when the tilting handle is the third angle for rolling thereby increasing the tension of said track, said track being taut, the offset device selectively disengaging the rollers of the conveyor belt thereby decreasing the tension of the track when the tilting handle is tilted in the first angle configured for ascending the staircase and the second angle configured for descending the staircase. 2. The rolling bag as described in claim 1, wherein the conveyor belt is set into a recess in a back of the rolling bag. 3. The rolling bag as described in claim 2, wherein the continuous track has an outer tread configured for traction. 4. The rolling bag as described in claim 3, wherein the offset device is a cam. 5. The rolling bag as described in claim 3, wherein the offset device is an eccentric roller. 6. The rolling bag as described in claim 1, wherein the tilting handle has a pair of telescoping supports, and a hand grip, a support on each side of the hand grip, the supports each having a plurality of vertical sections. 7. The rolling bag as described in claim 6, wherein the vertical supports of the telescoping handle each have a bottom having a pivot. 8. The rolling bag as described in claim 7, wherein the pivot has a ratchet, the ratchet configured for locking the vertical supports in place when a desired tilt is achieved. 9. The rolling bag as described in claim 7, wherein the telescoping handle supports have a pin that selectively locks the supports into a tilted position and selectively releases the supports from the tilted position to a substantially vertical position. 10. The rolling bag as described in claim 9, wherein the handle supports have a bottom section and the ratchet of the bottom section engages the offset device. 11. The rolling bag as described in claim 1, wherein the conveyor belt and the tilting handle are aligned in a substantially straight line when the tilting handle is fully extended and vertical. 12. The rolling bag as described in claim 11, wherein the tilting handle tilts about ten degrees upwards from the continuous track when ascending the staircase. 13. The rolling bag as described in claim 12, wherein the tilting handle tilts about fifty degrees upwards from the continuous track when descending the staircase. 14. A method for manufacturing a rolling bag configured for ascending and descending a staircase, comprising: coupling a tilting handle to a main compartment of a rolling bag, said handle configured for tilting into a plurality of angles, a first angle configured for ascending a staircase, a second angle for descending the staircase and a third angle for rolling, said handle telescopically retracting and extending to a plurality of lengths, a first length for ascending the staircase, a second length for descending the staircase and a third length for rolling;coupling a conveyor belt to a recess in a back of the main compartment, said conveyor belt having a continuous track and a plurality of rollers driving said track; andcoupling an offset device to the tilting handle at a bottom of the handle, the offset device selectively engaging the rollers of the conveyor belt thereby increasing the tension of said track, said track being taut and selectively decreasing the tension of the track when the tilting handle is tilted in the first angle configured for ascending the staircase and the second angle is tilted for descending the staircase.
