Problems solved by technology

As children get older, the frequency of backpack carrying and size of load carried increases, often exceeding a maximum recommended load.
The cumulative effects of many years of load carriage can cause many orthopedic and musculoskeletal injuries.
A large portion of previous research focused on the load size as the main problem when it comes to the kinematics adjustments of a human body and negative physical effects of load carriage.
During investigations, it was found that increased weight in a backpack resulted in significant compressive forces causing the spine, and therefore posture, to be altered.
A study conducted in 2006 actually focused on a group of significantly affected college students, found that carrying a load he

Embodiment Construction

[0015]The present invention relates to a backpack that alleviates the burden of carrying the loaded backpack while walking by its construction that suspends the load inside the backpack and allows it to move up and down in a movement that is out of phase with a gait of a wearer of the backpack.

[0016]Reference is now made to FIG. 1, A to D. Normal walking kinematics is quite complex as both the mechanical and postural phases are in continuous alteration and motion. As a result, a simplified understanding of what takes place within a normal gait is essential in order to fully comprehend the impact and postural deviations related to load bearing by a human body 10. Quite simply, the lower extremities of normal gait mirror a pendulum-like oscillation. During walking, the body 10 is continually supported by no less than a single leg 12 (FIGS. 1A, B and C), and supported by both legs when at a lowest vertical point (FIG. 1-D). The one leg that is planted during walking remains straight an...

Abstract

A backpack for carrying a load comprises a shoulder strap assembly, an exterior shell and a pouch for storing the load. The exterior shell has an opening and is attached to the shoulder strap. The pouch is located inside the shell and attached to it and comprises a stretchable portion. This stretchable portion is made of a material having an elastic modulus allowing it to stretch and retract when the load is placed inside the pouch so that the pouch moves down and up relative to the shell with a gait of a wearer of the backpack.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to the field of backpacks. More specifically, the invention relates to a backpack that is designed to ease the walking of a wearer while carrying a load in the backpack.BACKGROUND OF THE INVENTION[0002]Backpack carrying starts at a very young age for students. As children get older, the frequency of backpack carrying and size of load carried increases, often exceeding a maximum recommended load. The cumulative effects of many years of load carriage can cause many orthopedic and musculoskeletal injuries. People commonly complain about back pain, shoulder pain, and discomfort while wearing a backpack and these negative effects have prompted research on the physical demands of load carriage in attempts to create a physically less demanding product.[0003]Countless adaptations have been made in an attempt to alter attributes such as load placement and size, compression, strap placement, and energy expenditure. A large po...
