Abstract

A framed rucksack that has multiple independent load bases/levels intended to minimise unwanted forces upon the human body and have it work with the human body rather than against it. This design consists of a conventional rucksack with frame, a waist/hipbelt securing point and shoulder straps for stability. The rucksack has multiple independent load suspension bases/levels at various height levels on the rear of the frame, these bases/levels are not dependent on each of the other separate load bases/levels, allowing the load to be divided into different portions/sizes. These different bases/levels counterbalance and counteract each other and are utilised to the advantage of the body.

Claims

exact text as granted — not AI-modified
1 . A rucksack comprising of a stiff supportive frame with a waist/hipbelt encompassing waist of the wearer for attaching the frame to and a stabilising apparatus for the shoulders to stabilise the rucksack with the waist/hipbelt bearing the weight of the rucksack;
 with at least two separate load bearing containers each capable of suspending a load at a height without exerting loading on another container, that are to contain multiple items situated on the length of the back frame that are each capable of bearing significant weight of at least 5 kg, one of which is fixed at the base of the rucksack opposite the waist/hipbelt and at least one other higher up, with these levels giving different angular forces at the point of the waist/hipbelt, in which these differing angular forces will counteract and subdue each other;   one container has to be opposite the waist/hipbelt and one container with the lowest extremity at least 15% higher up the back length of the frame when the container is loaded with 5 kg.
