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. |
