Benefits of technology

The present invention is a backpack with extendable wheels called a backpack wheel extension. This backpack has built-in wheels that can be extended and engaged or disengaged while wearing the backpack. The backpack wheel extension helps to transfer the weight of the backpack to the ground surface, making the backpack lighter for the wearer and giving them more mobility to drag the backpack around instead of carrying the weight. The backpack wheel extension can be used with various backpack frames and can be an accessory for an existing backpack.

Problems solved by technology

These independent exoskeletons are bulky units.

Embodiment Construction

[0022]Referring now to the drawings wherein the depictions are for purposes of illustrating a preferred embodiment of the present invention only and not for the purpose of limiting the same. FIG. 1 is a side perspective view of a backpack wheel extension 100 of the present invention. The backpack wheel extension 100, has wheels which extends to the ground whereby transferring the weight of a backpack 12 to the ground. Attached to a backpack frame 10 are a left shaft 20 and a right shaft 40 and contained within the shafts are a left shaft extension 22 and a right shaft extension 42 respectively, which extends downwards to the ground. At one end of the left shaft extension 22 is a left pivoting wheel 30 and at one end of the right shaft extension 42 is a right pivoting wheel 50. FIG. 2 is a perspective view of the backpack wheel extension 100 with the left shaft extension 22 and the right shaft extension 42 stored with the wheels in the up position within the left shaft 20 and the rig...
