Definitions
- Rucksacks essentially consist of a bag with shoulder straps. They are known from ancient times. The disadvantage of rucksacks without frames is that they sag and sway under heavier loads. In modern times this problem has been addressed by the addition of hip belts and internal frames. The addition of frames has greatly reduced movement of the load, but has required the addition of padding to protect the back of the wearer. These additions have significantly increased the weight of rucksacks. Modern internal frame packs are essentially rucksacks with padded frames and hip-belts. They are comfortable to carry, but heavy.
- External frame packs essentially consist of a rigid frame having a pair of upright side rails and two or more vertically spaced arched cross-members. One or more tensioned cloth back support bands are mounted between the side rails to hold the frame away from the bearer's back. The load is either lashed to the frame or stored in a bag attached to the frame.
- the frames consisted of wood and steel, which made them quite heavy. As modern materials, particularly aluminum, have become available these packs have become lighter. Hip-belts have been added as well, reducing shoulder fatigue.
- 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.
- My invention overcomes all of these disadvantages by providing a plurality of strong, light vertical support members held as close as practicable to the bearer's body, separated only by a removable pad of a type which the bearer will normally carry for other uses, such as a backpacker's sleeping pad.
- 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.
- This invention provides an extremely light and comfortable backpack for carrying a load upon the back of the bearer. This is accomplished by minimizing the number and weight of the elements of the backpack and providing a means of incorporating a variety of types of removable padding, of a sort normally carried for other camping uses, into the backpack, thus avoiding the need for extra padding or other means of protecting the bearer's back from the load. This reduces the total weight of the load and holds it as close as practicable to the bearer's center of gravity.
- An embodiment of the invention consists of a sheath for insertion of a removable pad, to the posterior portion of which are affixed two or more vertical support members to which the load is attached. Shoulder straps are attached to the top and bottom of the sheath or the vertical support members, and a hip belt is attached to the vertical support members or the sheath.
- the sheath is made of a durable lightweight fabric such as nylon and is approximately rectangular in shape. It is of a size and shape to conveniently fit the bearer's back and suitable to hold a variety of removable pads, including folded backpacker's sleeping pads of different types.
- the vertical support members to which the load is attached are made of durable, lightweight material which is rigid but flexible, such as carbon fiber or fiberglass. A bag or bags may be attached to the vertical support members for convenient storage of the load.
- the shoulder straps and hip belt are made of durable lightweight material and are appropriately padded for the comfort of the bearer.
- This backpack is extremely simple, consisting of a sheath or similar means of containment for padding which will be carried by the bearer for other uses, a plurality of lightweight vertical support members, shoulder straps and a hip belt. It requires no additional straps, stays, horizontal structural members, tensioning devices or the like, thereby reducing weight to a minimum.

- People have used backpacks of various types for carrying loads on their backs for many years. Two basic types of packs are known from the prior art; rucksacks, with or without internal frames, and external frame packs. Patents and advertising disclose hundreds of variations on these two themes.
- Rucksacks essentially consist of a bag with shoulder straps. They are known from ancient times. The disadvantage of rucksacks without frames is that they sag and sway under heavier loads. In modern times this problem has been addressed by the addition of hip belts and internal frames. The addition of frames has greatly reduced movement of the load, but has required the addition of padding to protect the back of the wearer. These additions have significantly increased the weight of rucksacks. Modern internal frame packs are essentially rucksacks with padded frames and hip-belts. They are comfortable to carry, but heavy.
- External frame packs essentially consist of a rigid frame having a pair of upright side rails and two or more vertically spaced arched cross-members. One or more tensioned cloth back support bands are mounted between the side rails to hold the frame away from the bearer's back. The load is either lashed to the frame or stored in a bag attached to the frame. Originally the frames consisted of wood and steel, which made them quite heavy. As modern materials, particularly aluminum, have become available these packs have become lighter. Hip-belts have been added as well, reducing shoulder fatigue. 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.
- My invention overcomes all of these disadvantages by providing a plurality of strong, light vertical support members held as close as practicable to the bearer's body, separated only by a removable pad of a type which the bearer will normally carry for other uses, such as a backpacker's sleeping pad.
- A number of backpacks exist wherein the padding for the pack has been adapted for use in an auxiliary manner, as for seat cushioning or sleeping upon. 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.
- This invention provides an extremely light and comfortable backpack for carrying a load upon the back of the bearer. This is accomplished by minimizing the number and weight of the elements of the backpack and providing a means of incorporating a variety of types of removable padding, of a sort normally carried for other camping uses, into the backpack, thus avoiding the need for extra padding or other means of protecting the bearer's back from the load. This reduces the total weight of the load and holds it as close as practicable to the bearer's center of gravity.
- An embodiment of the invention consists of a sheath for insertion of a removable pad, to the posterior portion of which are affixed two or more vertical support members to which the load is attached. Shoulder straps are attached to the top and bottom of the sheath or the vertical support members, and a hip belt is attached to the vertical support members or the sheath.
- The sheath is made of a durable lightweight fabric such as nylon and is approximately rectangular in shape. It is of a size and shape to conveniently fit the bearer's back and suitable to hold a variety of removable pads, including folded backpacker's sleeping pads of different types. The vertical support members to which the load is attached are made of durable, lightweight material which is rigid but flexible, such as carbon fiber or fiberglass. A bag or bags may be attached to the vertical support members for convenient storage of the load. The shoulder straps and hip belt are made of durable lightweight material and are appropriately padded for the comfort of the bearer.
- This backpack is extremely simple, consisting of a sheath or similar means of containment for padding which will be carried by the bearer for other uses, a plurality of lightweight vertical support members, shoulder straps and a hip belt. It requires no additional straps, stays, horizontal structural members, tensioning devices or the like, thereby reducing weight to a minimum.
