Towable wheeled-backpack
A towable, wheeled-backpack includes a towing handle attached to a curved, single-pole, telescoping towing member which retracts into the backpack when not in use. The curvature of the towing member provides support for a backing sheet that is attached to the towing member, and the backing sheet is contoured so that the backpack can be comfortably supported on a wearer's back. A rigid base with wheels is pivotally attached to a bottom end of the towing member. The pivot attachment allows the base and wheels to move independently of the towing member as the bag is worn or as the bag is rolled along the ground.

a body defining at least one accessible storage compartment;
a towing base coupled to the body;
at least one wheel connected to the towing base;
a telescoping towing member having a first and a second end and a length therebetween, said towing member selectively postionable in a retracted position and an extended position relative to said towing base; and
wherein said towing member is arched along the length thereof and has a non-circular cross section; and
wherein said towing member extends along a curved path upwardly and laterally away from said body when said towing member is in said extended position, such that the first end of said towing member is vertically and horizontally displaced from said base when said towing member is in said extended position.
2. The piece of baggage of claim 1 , wherein the towing member is positioned significantly internal to said body when in said retracted position.
3. The piece of baggage of claim 1 , wherein the arched towing member has a substantially constant radius of curvature along said length.
4. The piece of baggage of claim 1 , wherein the curved path extends away from the body.
5. The piece of baggage of claim 1 , wherein the towing member comprises a single pole telescoping member.
6. The piece of baggage of claim 1 , wherein said towing base is a rigid base.
7. The piece of baggage of claim 1 , wherein said first end is positioned over said base when the towing member is in said retracted position.
8. The piece of baggage of claim 1 wherein:
said body has opposing front and back portions, opposite top and bottom portions, and opposite left and right sides; and
the at least one wheel comprises first and second wheels, each of said first and second wheels mounted for rotation on said left and right sides, respectively.
9. The piece of baggage of claim 1 , wherein said body defines at least one of a backpack and suitcase.
10. The piece of baggage of claim 1 , wherein at least one of said at least two portions of said towing member has an oval cross-section.
11. The piece of baggage of claim 1 , further comprising a shoulder strap.
12. The piece of baggage of claim 1 , wherein said body is fabricated from a flexible material.
13. The piece of baggage of claim 1 , wherein said towing member comprises a plurality of telescoping members, each of said telescoping member having a cross-section that prevents relative twisting between said plurality of towing members.
14. The piece of baggage of claim 1 , further comprising a backing sheet located between said towing member and a front portion of said body.
15. The piece of baggage of claim 1 , further comprising a backing sheet located between said towing member and a front portion of said body.
16. A piece of baggage designed to be pulled behind a person comprising:
a body defining at least one accessible storage compartment;
a towing base coupled to the body;
at least one wheel connected to the towing base;
a curved and rigid telescoping towing member having a first and a second end and a length therebetween, said towing member comprising at least two portions slidably postionable in a retracted position and an extended position relative to said towing base, each of said portions of said towing member having a cross section selected to prevent the portions from twisting relative to one another; and
wherein a portion of said length of said towing member is arched along an axial length extending between opposing ends; and
wherein said towing member extends along a curved path upwardly and laterally away from said body when said towing member is in said extended position, such that the first end of said towing member is vertically and horizontally displaced from said base when said towing member is in said extended position.
17. The piece of baggage of claim 16 , wherein the telescoping member is a single-pole towing member.
18. The piece of baggage of claim 16 , wherein body defines at least one of a backpack and a suitcase.
19. The piece of baggage of claim 16 , wherein the cross section is oval.
20. The piece of baggage of claim 16 , wherein the arched towing member has a substantially constant radius of curvature along said length.
21. The piece of baggage of claim 16 , wherein the curved path extends outwardly and away from said body to laterally space said first end from the body and the base when the towing member is extended.
22. The piece of baggage of claim 16 , wherein said first end is positioned over said base when the towing member is retracted.
