Recreational Equipment, Inc. - Kent WA

International Classification:

A45F 304

US Classification:

Abstract:

A backpack load transfer and stabilization system includes a roll control rod coupled to a hip belt for a backpack. The control rod is contained entirely within the hip belt and extends across the width of the hip belt. The control rod is coupled, in turn, to semi-rigid extension members which serve as the interface between the hip belt and the main backpack. The extension members transfer the load to locations on the hip belt corresponding to hip locations of the person wearing the backpack. The extension members are rotatably coupled to the main backpack and rigidly coupled to the roll control rod, such that when a person wearing the backpack hikes, and the persons hips move up and down, the combination of the roll control rod and interconnected extension sections compensate for the up-and-down movement of the hips to stabilize the load and prevent side-to-side swaying.

Abstract:

A lightweight, portable shelter structure is provided having an aerodynamically stable configuration which is particularly resistant to wind loads. The stability of the shelter structure results from the construction of the canopy portion wall panels and their interaction with the rod members of the shelter. The canopy portion is formed of an elastic material so that the base of the canopy panel may be stretched to tension the rod members, which are formed of a resilient, flexible material. In a preferred embodiment, the canopy panel has a triangular configuration, and the rod member is secured at the base and at the apex of the triangle so that when the base is stretched, compressive forces are exerted on the rod member causing it to bow. The canopy of the present shelter structure includes at least two panels of this construction and the shelter further includes a loose, expandable floor portion attached to the canopy portion. An arrangement of ventilating structures creates air flow through the shelter and effectively reduces condensation.
