Ultralight Backpack

Abstract

A backpack of very simple construction is disclosed, which uses modern materials and elements to achieve great comfort and extreme light weight. A sheath is made of light, strong cloth or other pliable material, constructed so as to contain a folded backpacker's sleeping pad or other suitable removable pad, and hold it against the bearer's back. To said sheath are attached a plurality of spaced-apart vertical support members made of a light, rigid but flexible material, for attachment and support of the load. A pair of shoulder straps and a hip belt are attached for securing the backpack to the bearer's back.

AI Technical Summary

Benefits of technology

This patent describes a backpack that is very light and comfortable for the user to carry a heavy load on their back. This is achieved by using a minimal number of components and a removable padding system that can be added to the backpack. The backpack has a sheath made of light fabric that can hold various types of padding, and it is attached to the user's back with vertical support members made of light but rigid material. The shoulder straps and hip belt are also made of light but padded material for added comfort. This backpack design requires no additional straps, stays, or horizontal structural members, making it the lightest and simplest backpack on the market.

Problems solved by technology

They are known from ancient times. The disadvantage of rucksacks without frames is that they sag and sway under heavier loads.

These additions have significantly increased the weight of rucksacks.

They are comfortable to carry, but heavy.

Originally the frames consisted of wood and steel, which made them quite heavy.

External frame packs have proven to be useful for carrying heavy loads, but suffer from the disadvantage that they are wide and bulky.

They also increase fatigue by carrying the load away from the bearer's body, thereby altering the body's natural balance.

However, the prior art discloses no backpack designed to use a variety of types of padding normally carried by backpackers for other camping purposes, such as backpacker's sleeping pads, as part of the backpack, itself.
