Benefits of technology

[0003] The invention is a backpack having a forked frame made of curved flat members that are shaped to approximately conform to and press against the curvature of a wearer's back. For the purpose of visualizing what is meant by “curved flat member,” one may liken the shape of these members somewhat to the shape of a steel leaf spring used in the automotive industry. In other words, the curved flat members used in the present invention are dimensionally long and wide, relative

Embodiment Construction

[0018] Referring now to the drawings, and first to FIG. 1, shown generally at 10 is a backpack constructed in accordance with the invention summarized above. The backpack has a forked frame, indicated generally at 12. The frame has two curved flat members 14, 16 that are connected together by a handle portion 17. Referring now to FIG. 7, which is a back view of the frame 10 disconnected from the pack or packsack 40, the lower portions of the flat members 14, 16 flare outwardly as indicated at 18, 20, respectively.

[0019] As is best seen in FIG. 2, the lower-most region of the outwardly flaring parts or frame regions 18, 20 are lumbar-supporting areas or portions, indicated at 22, 24, respectively. Attached to these areas are two lumbar pads 26, 28. Similarly, a scapular pad 30 is connected to the flat members 14, 16 near the handle portion 18. The connection of the pads 26, 28, 30 to the frame 12 can be done in different ways. In the embodiment illustrated here, the connection is ma...

Abstract

A backpack having a forked frame with curved flat members that are shaped to conform to the curvature of a wearer's back. The flat members are connected together torsionally by a handle portion that allows each flat member to shift relative to the other to accommodate weight shifts in the backpack load. The forked frame is a single-piece structure that is preferably made of carbon fiber. Although the frame is external relative to the pack, the flat construction of the frame allows it to mate with the pack in a way such that the frame is integrated with the inner sidewall of the pack.

Description

TECHNICAL FIELD [0001] The present invention relates to backpacks, and more particularly, to backpacks having flexible frames. BACKGROUND OF THE INVENTION [0002] Conventional backpacks typically have a rigid tubular metal frame that is external of the pack or an internal frame. Either way, the frame supports the load within the pack and distributes the load across the wearer's hips, shoulders, and back. The invention disclosed here is a new frame design that provides a different way of supporting backpack contents and distributing the weight carried by the pack. SUMMARY OF THE INVENTION [0003] The invention is a backpack having a forked frame made of curved flat members that are shaped to approximately conform to and press against the curvature of a wearer's back. For the purpose of visualizing what is meant by “curved flat member,” one may liken the shape of these members somewhat to the shape of a steel leaf spring used in the automotive industry. In other words, the curved flat m...
