A collapsible and expandable carrying device for pulling, carrying, or otherwise transporting luggage, cargo, or any other items. The carrying device comprises a frame comprised of and combined with additional telescopic rods for adjustment of parameters for ease of use. The frame is pivotally attached to a handle, support straps, shoulder straps, and/or a belt to be attached to a user's waist. The device is meant for both short and long travel, and it allows for a user to vary angles and lengths of the constituent parts in order to minimize gravitational load on the user and optimize the force of the center of gravity from the load being carried.

1. A collapsible carrying device for transporting luggage and cargo, comprising: a rectangular back frame, said rectangular back frame being pivotally attached to a base, said base being further pivotally attached to a support bar, said back frame, base, and support bar forming a carrying platform,two wheels, said wheels being disposed on opposing ends of said base, said wheels being at least 100 millimeters in diameter,one or more primary telescopic rods extending from said carrying platform, said primary telescopic rods being pivotally attached to said carrying platform, thus allowing for adjustment of an angle between said primary telescopic rods and said rectangular back frame of said carrying platform, said angle being based on the weight of the luggage or cargo being carried and one or more physical parameters of a user,a first pair of shock absorbers, said first pair of shock absorbers being positioned along a vertical portion of said rectangular back frame to absorb shock from uneven terrain, and one or more second shock absorbers, said second shock absorbers being positioned in alignment with a portion of each primary telescopic rod to minimize shock from an inertia of said carrying platform with said luggage or cargo,wherein said carrying platform, wheels, and rods collapse to form a substantially flat shape when not in use. 2. The device of claim 1, further comprising a detachable handle coupled to said primary telescopic rod for maneuvering said device via a user's hand. 3. The device of claim 2, wherein said handle coupled to said primary telescopic rod comprises a ball-and-socket connection, thus allowing for a multi directional pivoting. 4. The device of claim 1, further comprising a detachable clip coupled to at least one of said telescopic rods, said clip being further attachable to a belt of a user for maneuvering said device hands free. 5. The device of claim 4, further comprising a shoulder strap extending from said clip, said shoulder strap being wearable over a shoulder of a user for further support. 6. The device of claim 1, further comprising a harness belt pivotally attached to each telescopic rod, said harness belt being further wearable by a user for maneuvering said device hands flee. 7. The device of claim 6, wherein said harness belt is adjustable based on a user's waist size. 8. The device of claim 1, further comprising two shoulder straps, said shoulder straps being attached to said rectangular frame for carrying said device as a backpack. 9. The device of claim 1, wherein said wheels are detachable. 10. The device of claim 9, wherein said wheels are re-attachable in a second position to a portion of said rectangular back frame when the device is collapsed. 11. The device of claim 1, wherein said wheels comprise whole-rubber tires. 12. The device of claim 1, wherein said wheels comprise pneumatic tires. 13. The device of claim 1, wherein said angle between said rod and said rectangular back frame is adjustable for the same user based on a size and weight of said luggage or cargo, such that a center of gravity of said carrying platform with luggage or cargo remains over said wheels, and such that minimal force is placed on a user maneuvering said device. 14. The device of claim 1, further comprising one or more intermediate telescopic rods, said intermediate telescopic rods being positioned as angular support between said primary telescopic rods and said carrying platform, wherein said intermediate telescopic rods each have a third shock absorber, and wherein a position of each intermediate telescopic rod is adjustable via preset connections, thus stabilizing the angle between said primary telescopic rods and said rectangular back frame of said carrying platform. 15. The device of claim 1, wherein each shock absorber is a two-way (bilateral traction) shock absorber. 16. The device of claim 1, wherein said carrying platform further comprises crossbars. 17. The device of claim 1, wherein said rectangular back frame is expandable. 18. The device of claim 1, wherein said base is expandable. 19. The device of claim 1, wherein one or more pivotally attached connections further comprise one or more amortizators. 20. The device of claim 1, wherein said primary telescopic rods are pivotally attached to a vehicle.
