Backpack system
Abstract:
A frame assembly includes a base frame member, an upper frame member and a canopy frame member. Each of the frame members is fabricated of a rigid metallic tube in an inverted U-shaped configuration with a closed end and essentially parallel legs terminating in lower free ends. Pins pivotally couple the frame members with respect to each other adjacent to their free ends. The base frame member has a forward face with shoulder straps and a waist strap secured to the base frame member and extending forwardly for releasably coupling the base frame member to a carrier's back. A canopy sheet spans the canopy frame member and the upper frame member. A first pull cord has a fixed end secured to the canopy frame member and a second end extending forwardly of the base frame member for being pulled by the carrier to deploy the canopy frame member and the canopy sheet to an extended orientation.
