FIG. 4 illustrates an embodiment of a container mounted in an upper door in the upper compartment of a rigid backpack in accordance with the invention. -
FIG. 5 illustrates an embodiment of the lower compartment as a cooker in accordance with the invention. - A description of a rigid backpack for use in carrying and storing items that require cooling or are easily damaged, such as food, canned or bottle drinks and so forth, is provided. The rigid backpack includes at least one compartment and can include upper and lower compartments. The compartments are formed from rigid materials such as metal or formable plastics.
- Separable lower and upper compartments of a rigid backpack are shown in
FIG. 1 . Generally, the compartments are polyhedrals with flat or curved surfaces. Alternatively, the compartments can have other shapes that are more spherical, have special design surfaces that reflect logos, and so forth. The compartments are rigid, and can be formed from either a single layer of material or from multiple layers. Non-rigid layers can be used in combination with other layers of material so long as the overall combination of layers is rigid. For example, to insulate a compartment an outer metal layer that is rigid can be combined with a less rigid insulating layer. The rigid material can include metal, plastic, carbon fiber based materials, and so forth. The rigid material can be opaque or clear, for example clear plastic. - The
lower compartment 101 has atop wall 105 and alower door 109. Thelower door 109, which can have a recessed latching mechanism, is used to access the space inside thelower compartment 101. Thelower compartment 101 can be formed with an insulating layer of material and have a leak-resistant design so as to function as a cooler. Alternatively thelower compartment 101 can be formed from metal, such as aluminum or stainless steel, and used as a stove when separated from theupper compartment 103 and when a heat source such as Sterno is placed inside. - The
upper compartment 103 has abottom wall 107, and anupper door 111. Thebottom wall 107 of theupper compartment 103 and thetop wall 105 of thelower compartment 101 have complementary surfaces that allow theupper compartment 103 to stack on top of and be removably attached to thelower compartment 101. Theupper door 111, which can have a recessed latching mechanism, is used to access the space inside theupper compartment 103. Theupper compartment 103 can havecylindrical container holders top 113. Theupper compartment 103 can be formed with an insulating layer of material and have a leak-resistant design so as to function as a cooler. - A rigid backpack as formed by the attachment of an upper compartment and a lower compartment is as shown in
FIG. 2 . Various means of attachment, such as clips, detents, springs, dowels, zippers, snaps, Velcro, and so forth, can be used to secure the two compartments to each other. Generally, when the two compartments are attached together, adjacent surfaces of the compartments form a continuous surface. The surfaces that will be next to a person's back are ergonomically formed. For example, afirst surface 119 of thelower compartment 101 is ergonomically formed as is a first surface 121 of theupper compartment 103. When the compartments are attached together thecompartment surfaces 119, 121 form an approximately continuous surface that is ergonomically formed. - A
waist strap 123 and optional lower padding 125 are attached to thefirst surface 119 of thelower compartment 101. Similarly, aright shoulder strap 127, aleft shoulder strap 129, and optionalupper padding 131 are attached to the first surface 121 of theupper compartment 103. Alternatively, the waist and shoulder straps can be attached to other parts of the respective compartments.Support members 133 are attached to a bottom of thelower compartment 101, and are used to facilitate the standing of the lower compartment and the rigid backpack in an upright position when placed on a surface such as on the ground. When the compartments are separated, theupper compartment 103 andshoulder straps rigid day pack 210, and thelower compartment 101 andwaist strap 123 form arigid fanny pack 220. - A single integrated rigid backpack having an upper compartment and a lower compartment that share a common wall in accordance with the invention is shown in
FIG. 3 . In this embodiment, theupper compartment 103 and thelower compartment 105 are formed as a single integral backpack 300. The upper and lower compartments are attached to each other by a single common wall (not shown). The common wall forms a top of thelower compartment 301 and a bottom of theupper compartment 303. Alower door 309 allows access to the space inside thelower compartment 301. Similarly, anupper door 311 allows access to the space inside theupper compartment 303. - An embodiment of a container mounted in an upper door in the upper compartment of a rigid backpack is shown in
FIG. 4 . The container (not shown) that is attached to theupper door 111 extends into the upper compartment 130. The container is formed for the storage of small items such as cigarette pack, lighter, sunglasses, or so forth that can be difficult to find or may be damaged if placed inside either theupper compartment 103 or the lower compartment (not shown). Anaccess door 135 for the container is mounted in theupper door 111. - An embodiment of the lower compartment as a cooker is shown in
FIG. 5 . For this embodiment the waist strap and padding are removed, and thelower compartment 501, which is preferably constructed from metal, is positioned on a generally level surface. Thelower compartment 501 includes alower door 503 and acooking surface 507.
