Benefits of technology

"The present invention is about a pivot system for a backpack that allows the wearer to move laterally while still carrying the pack on their hips. This system allows for independent movement without compromising the stability of the load. The backpack is attached to a frame and a waist belt, which can rotate with respect to the frame. This rotation is caused by the wearer's hip movements while wearing the backpack. The system includes a spacer that offsets the top of the waist belt from the frame, creating a predetermined angle for better load transmission. This invention allows for comfortable and efficient backpacking."

Problems solved by technology

Backpacks often cause discomfort and pain on the part of the backpack wearer resulting from pressure points at any of a number of locations.
Typical areas of backpack wearer discomfort include the shoulders, hips and the back itself, which may become strained if too much of a load has been carried on the shoulders rather than on the hips, for an extended period of time.
It has been found that pressure points may develop due to a lack of flexibility between the waist belt and the frame member, which results in the pack not fitting as well as desirable.
An additional problem associated with heavy-load backpacks is that conventional frame and suspension systems that are strong enough to support very heavy loads (e.g., in excess of 70 lbs) do not provide the flexibility necessary to follow the backpack wearer's body movements.
Moreover, such frames do not provide for the natural motion of hips and shoulders to reduce fatigue.

Abstract

The present invention provides a backpack comprising a frame for supporting one or more bags, a waist belt attached to the frame for supporting the frame around the waist of a backpack wearer, and a pivot system for attaching the waist belt to the frame to permit rotation of the waist belt with respect the frame, the pivot system comprising a bracket that is fixedly attached to the frame, and a single pivoting axle for attachment of the waist belt to the bracket.

Description

RELATED APPLICATIONS [0001] This application claims priority to U.S. Provisional Patent Application No. 60 / 791,974, the content of which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION [0002] This invention broadly relates to backpacks and more particularly to a pivot system for a backpack that permits rotation between a waist belt and a backpack frame. BACKGROUND OF THE INVENTION [0003] Backpacks often cause discomfort and pain on the part of the backpack wearer resulting from pressure points at any of a number of locations. This is especially so for heavy-load backpacks, such as those used by Special Forces and other military personnel in field missions. Typical areas of backpack wearer discomfort include the shoulders, hips and the back itself, which may become strained if too much of a load has been carried on the shoulders rather than on the hips, for an extended period of time. [0004] Conventional heavy-load backpacks feature a frame member, shoulder...
