Abstract
A back pack including a bag provided with an internal frame comprising a pair of diagonally crossed blade-like bands secured to each other at a crossover zone, and secured to the bag by a pair of pockets at the upper extremities of the bands and by a pair of anchor pins at the lower extremities. The pack frame is given a slight arcuate curvature by tensioning strips impressing force between upper and lower extremities of the bands, and the tensioning strips are bridged by a mesh panel. Also included are a collapsible internal shelf and straps that can be used either as lashing straps for securing loads to the exterior of the pack or as load hauling straps for lifting and lowering the pack during climbing operations.
Claims13
In a back pack of the type used by hikers and climbers as a body-carried container for transporting articles, said back pack including
- a sack-like bag having wall means including
- a floor,
- side wall means attached to, surmounting and extending upwardly of the floor, said side wall means including a front wall means oriented to face the back of a wearer of said back pack, and a closure for the bag;
- frame means and means attaching said frame means flatly to said front wall means to impart structural rigidity to the bag and to obviate vertical collapse of said front wall means;
- the improvement wherein said frame means comprises a pair of elongated, blade-like bands disposed contiguously to cross one another and to define an X-configuration at a crossover zone thereof, said bands being independent of auxiliary frame members interconnecting opposed upper and lower diagonally opposed extremities of the bands to one another;
- a pair of fastening means interconnecting the bands to one another in the crossover zone to preclude scissors-like movement of the bands relative to each other;
- and
- means to maintain said bands in an arcuate curvature along the length thereof, thereby to provide a zone of spatial separation between the front wall means of the back pack and the back of a wearer of the back pack.

- and wherein said back pack further comprises strip means bridging said bands along the length thereof and disposed on a side of said front wall means opposed to said bands,
- said strip means constituting a pair of strips for selectively impressing a tensioning force between upper and lower extremities of said blade-like bands to maintain an arcuate curvature along the length thereof, thereby to provide a zone of spatial separation between the front wall means of the back pack and the back of a wearer of the back pack.

- a pair of strips for selectively impressing a tensioning force between upper and lower extremities of said blade-like bands;
- an air-permeable sheet-like panel overlying an area disposed between said strips;
- and
- means attaching said panel to said strips, said panel being adapted to engage and to bear upon the back of a wearer of said back pack, thereby to provide a zone of spatial separation between the front wall means of the back pack and the back of a wearer of the back pack.
