A wheeling frame for a suitcase which has its own rolling wheels includes a frame supporting a pair of leaning wheels arranged at ends of a pair of pivotable legs, with a first wheel arranged at the end of a first leg and a second wheel arranged at the end of a second leg. The leg positions are adjustable between a stowed position and a deployed, adjustable position extending at an angle to the frame. The legs have a movable pivoting axis and adjustable lengths. A handle system at a proximal end of the frame is adjustable in length and angle, and is operable in conjunction with the leaning wheels to roll the suitcase in a stable leaning position, to allow walking the suitcase on steps of a staircase, and to be converted into a suitcase table, to ease packing and unpacking.

1. A wheeling frame for wheeling a load which is rollable on its own load supporting wheels, the wheeling frame comprising: a frame defining a frame plane, the frame being removably securable to the load in such manner that the load is rollable and its weight is supported on said load supporting wheels;a wheeling leg assembly stowable in the frame and movable between a first position in the frame plane and a second position extending at an angle to the frame plane;at least one leaning wheel secured to the wheeling leg assembly, and the wheeling frame being structured so that it lacks its own load bearing wheels for supporting the load; anda fastening system structured to removably secure the wheeling frame to the load, whereby, when the wheeling frame is secured to the load, the load can be rolled such that its load is substantially carried by the supporting wheels while also leaning on the at least one leaning wheel of the wheeling leg assembly; anda spring biased mechanism configured and biased to urge the wheeling leg assembly toward the second position and yieldingly hold the wheeling leg assembly at the second position, the wheeling frame being so constructed that the at least one leaning wheel is only yieldingly held at the second position. 2. The wheeling frame of claim 1, wherein the angle of the second position is adjustable, wherein the wheeling leg assembly comprises a lost motion mechanism which is configured to enable setting of the angle of the second position. 3. The wheeling frame of claim 2, wherein the lost motion mechanism enables the legs of the wheeling leg assembly to pivot away from the adjustable angle position. 4. The wheeling frame of claim 1, wherein the load is a suitcase. 5. The wheeling frame of claim 4, wherein the wheeling leg assembly comprises first and second spaced legs, each having its respective leaning wheel secured thereto. 6. The wheeling frame of claim 5, wherein the wheeling frame extends lengthwise and has a first end and a second end, the wheeling leg assembly being structured to place the leaning wheels closer to the first end, and further comprising a handle assembly which is retractably mounted in the frame and which is structured to extend out of the frame generally in the direction away from the second end of the frame. 7. The wheeling frame of claim 6, wherein the handle assembly includes a pivotable handle which is structured to be pivotable relative to the frame plane. 8. The wheeling frame of claim 7, wherein the handle assembly comprises extendible arms, which are structured to cooperate with the wheeling leg assembly to enable the frame to be supported horizontally on the wheeling leg assembly adjacent the first end of the frame and on the handle system adjacent the second end of the frame, to provide a table mode in which the suitcase is supported on the frame in a horizontal position. 9. The wheeling frame of claim 4, wherein the wheeling leg assembly is structured to pivot out of the frame plane about a pivot axis, and an adjusting mechanism structured to allow adjusting an inclination angle of the wheeling leg assembly relative to the frame plane. 10. The wheeling frame of claim 9, wherein the location of the pivot axis of the wheeling leg assembly is adjustably movable along the wheeling frame. 11. The wheeling frame of claim 4, wherein a location of the wheeling leg assembly relative to the frame is adjustable to set a distance between the leaning wheels of the wheeling leg assembly and the load supporting wheels of the load to which it is secured, to match the pitch of the steps of a staircase, on which the wheeling frame is configured to travel up the steps, so that the load always remains in contact with the steps via either the leaning wheels or the load supporting wheels. 12. The wheeling frame of claim 4, wherein the fastening system comprises a plurality of interlocking straps which are structured to grasp around and tightly secure the load to the wheeling frame. 13. A wheeling frame for wheeling a load which is rollable on its own load supporting wheels, the wheeling frame comprising: a frame defining a frame plane;a wheeling leg assembly stowable substantially in the frame and moveable between a first position in the frame plane and a second position extending at an angle to the frame plane;at least one leaning wheel secured to the wheeling leg assembly;a handle system mechanically coupled to said frame;wherein said frame, wheeling leg assembly and said handle system are configurable to allow the load to be used in a leaning mode in which the load can be pushed or pulled while leaning on said at least one leaning wheel and a table mode wherein said load is supported at an elevated horizontal position on said handle system and on said wheeling leg assembly, the wheeling frame being structured so that it lacks its own load bearing wheels for supporting the load; anda spring biased mechanism configured and biased to urge the wheeling leg assembly toward the second position and yieldingly hold the wheeling leg assembly at the second position, the wheeling frame being so constructed that the at least one leaning wheel is only yieldingly held at the second position. 14. The wheeling frame of claim 13, wherein the frame comprises first and second parallel, spaced and lengthwise extending members and a first widthwise extending member connecting one end of the lengthwise extending members. 15. The wheeling frame of claim 13, wherein the frame is defined by structural frame members and the structural frame members of the frame define an interior frame space which has a length, a width and depth, wherein the depth measures less than about 2 inches.
