CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 63/352,433 filed June 15, 2022, the entire contents of which are incorporated herein by reference.

FIELD OF THE DISCLOSURE

[0002] This disclosure relates to backpacks, and more particularly, to a modular backpack system.

BACKGROUND OF THE DISCLOSURE

[0003] Backpacks are useful for carrying a variety of items. For example, backpacks can be used to carry work items such as laptops and necessary power cords, as well as travel items such as clothing and toiletries. When traveling, a large capacity backpack may be necessary to store enough items for the duration of the trip. Depending on the occasion, however, it can be useful to have a small capacity backpack that only stores necessary items for a shorter period. For instance, a user may want to use a smaller capacity backpack for a short trip to a coffee shop, or to carry essential items the user intends to use for a day trip. Thus, it can be desirable to have both a large capacity and a small capacity backpack as necessary for a given use.

[0004] For obvious reasons, it can be difficult to use a small capacity backpack to store a large number of items. When using a large capacity backpack to store a number of small items only a short period or occasion, however, the large capacity backpack can be unseemly and add unnecessary bulk and weight. Additionally, if a user were to use a large backpack capacity backpack when traveling but desire to only carry a few items from that backpack on a given day, the user must entirely unpack all of the other items, and then re-pack them at a later time. Rather than carry two backpacks of varying sizes, ideally, the user would carry one backpack but be able to easily and quickly customize that backpack to be either large capacity or smaller capacity based on the occasion.

SUMMARY OF THE DISCLOSURE

DETAILED DESCRIPTION OF THE DISCLOSURE

[0055] Reference will now be made in detail to implementations and embodiments of various aspects and variations of systems and methods described herein. Although several exemplary variations of the systems and methods are described herein, other variations of the systems and methods may include aspects of the systems and methods described herein combined in any suitable manner having combinations of all or some of the aspects described. [0056] In the following description of the various embodiments, it is to be understood that the singular forms “a,” “an,” and “the” used in the following description are intended to include the plural forms as well, unless the context clearly indicates otherwise. It is also to be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It is further to be understood that the terms “includes, “including,” “comprises,” and/or “comprising,” when used herein, specify the presence of stated features, integers, steps, operations, elements, components, and/or units but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, units, and/or groups thereof.

[0057] Backpacks are useful objects for a variety of purposes. Features that are desirable in one setting, however, may be less desirable or entirely unnecessary in others. For example, a large capacity backpack can be useful when storing large items or numerous smaller items. However, a fully-utilized large capacity backpack, i.e., one that is packed to maximum capacity, may be relatively heavy and cumbersome to carry for extended periods. Thus, a smaller capacity backpack, which is likely lighter and easier to carry than a large capacity backpack, may be desirable in certain instances.

[0058] Rather than having a dedicated backpack for each type of setting, a modular backpack system that enables a user to customize their backpack as necessary can strike a balance between capacity and weight (as an example). In one or more examples, a backpack that can be configured and reconfigured to match the circumstances as needed can allow the user to match the capacity of the backpack to their needs without having to purchase separate backpacks for each possible need. In one or more examples, and as described in further detail below, a backpack can be configured to be “modular” to allow the user to tailor the backpack for a particular use. In one or more examples, the modular backpack system can have a number of modules each compatible with one another that can increase or decrease the capacity of the backpack according to the user’s requirements. Moreover, a modular backpack system that facilitates quickly and easily adding or removing modules would enable the user to have a single backpack that can be used in every setting simply by adding or removing modules as necessary. In one or more examples, by reducing the weight of the backpack when certain modules aren’t needed, the user can strike a balance between weight and capacity based on their current needs and the specific context that the bag is to be used in. [0059] Accordingly, disclosed herein is a modular backpack system for creating a customized modular backpack. A modular backpack can be assembled by attaching appropriate modules of the modular backpack system to one another to form a modular backpack. For instance, a modular backpack can include a front module that is attached to a back module, with the back module including shoulder straps such that the user can wear the backpack.

[0060] The modules of the modular backpack system can be compatible with one another such that modules can be connected to one another as necessary. A user could connect just a front and back module to one another, or could include any number of center modules that are located between the front and back modules. To connect the modules, the user can rely on any suitable attachment element that enables a user to quickly and efficiently add or remove modules as necessary. For instance, the attachment elements could include zippers, Velcro, buttons, hooks, buckles, stud buttons, magnets, etc.

[0061] The back modules that are compatible with the modular backpack system can include a ballistics pocket for storing a protective ballistics plate. The ballistics plate can be positioned in a storage position, such as in a pocket of a back module, or in a deployed position, where the ballistics plate covers the torso of the wearer of the backpack. When in the deployed position, the ballistics plate can be connected to the back module of the modular backpack via a suitable attachment element, such as by a zipper, hooks, etc. The ballistics plate may include a separate set of shoulder straps that can rest on top of the shoulder straps of the back module when the ballistics plate is deployed.

[0062] The center modules that are compatible with the modular backpack system can include a variety of access elements that permit the wearer to access the interior of the module (and thus the contents of the modular backpack). For instance, a center module can include side access panels that are accessible when the center module is mounted on a modular backpack. In one or more examples, a center module can include a top access panel that is only accessible when the center module is not mounted on a modular backpack. In one or more examples, the center modules can be compatible with additional modules that can be affixed to or inserted into the center module. For instance, the modular backpack system can include additional interior modules that fit within a given center module. The modular backpack system can include panels that provide secure pockets that can be releasably closed, loops, open pockets, etc. such that a user can further customize their modular backpack. [0063] The front modules that are compatible with the modular backpack system can include a variety of attachment elements that can mount additional modular items to the modular backpack. For instance, a front module can include attachment elements that permit the user to attach modular pockets to the front module. A front module can include hooks or other attachment elements that permit the user to attach a net or other containment element to the front of the modular backpack. In one or more examples, a front module can provide a hard shell formed via a manufacturing process such as compression molding that provides a protective cover for the modular backpack.

[0064] FIG. 1 illustrates a perspective view of an exemplary modular backpack system 100, in accordance with one or more examples of the disclosure. As shown in FIG. 1, the modular backpack system 100 includes a modular backpack 101, which includes a front module 102, a center module 104, and a back module 106, with the center module 104 occupying the space between a front zipper 103 and a back zipper 105. The modular backpack system 100 can include a number of different modules that are all compatible with one another and can be used to build a custom modular backpack such as modular backpack 101. A given modular backpack 101 can thus include a specific configuration of modules, such as the front module 102, the center module 104, and the back module 106, of the modular backpack system 100.

[0065] In one or more examples, to connect the modules of the modular backpack 101, a user can use a zipper at both the front zipper 103 and back zipper 105 to zip the modules together. For example, when assembling the modular backpack 101, the user can zip the center module 104 to the back module 106 at the back zipper 105, and then zip the front module 102 to the center module 104 at the front zipper 103.

[0066] In one or more examples, the modular backpack 101 can include any number of center modules. For instance, if a user desired to use two center modules, they could add an additional center module connected to the center module 104 on one side of the center module 104 adjacent to either the front module 102 or to the back module 106, depending on which side of the center module 104 the additional center module is connected to. For example, if a user connected the center module 104 to the back module 106 at the back zipper 105, the user could then connect an additional center module to the front of the center module 104, and in turn connect the additional center module to the front module 102.

[0067] In one or more examples, the modular backpack system 100 can include a variety of center modules with varying features, such as different configurations of handles and/or access panels, a variety of front modules with varying features, and a variety of back modules with varying features, with each of the different modules sharing compatible interface features such that the modules can be affixed to one another when combining them into a backpack. As shown in FIG. 1, the modules can be affixed to one another via zippers at the front zipper 103 and the back zipper 105. However, the invention is not limited solely to zippers, and other attachment elements may be used, such as Velcro, buttons, hooks, buckles, stud buttons, magnets, etc.

[0068] In one or more examples, the modular backpack 101 can include a variety of attachment elements at a single attachment interface. For example, the modular backpack 101 can include magnets on adjacent modules that facilitate connecting the modules together by ensuring they are properly aligned before the modules are affixed by another attachment element. For example, the center module 104 and the back module 106 could each include opposing magnets that when brought close together temporarily hold the center module 104 and the back module 106 in the appropriate position relative to one another such that the modules can be zipped together via a zipper at the back zipper 105.

[0069] FIG. 2 illustrates a perspective view of a segmented lumbar back module 200 for a modular backpack, in accordance with one or more examples of the disclosure. In one or more examples, the segmented lumbar back module 200 can be used for the back module 106 of the modular backpack 101 of FIG. 1. Thus, in one or more examples, the segmented lumbar back module 200 can be one possible implementation of the back module 106 that is suitable for use in a modular backpack system such as modular backpack system 100.

[0070] In one or more examples, and as shown in FIG. 2, the segmented lumbar back module 200 can include a zipper 202, a side grab handle 204, a top grab handle 206, straps 208, and lumbar support pads 210. If the segmented lumbar back module 200 is incorporated into a modular backpack, the zipper 202 can act as the attachment interface for attaching the segmented lumbar back module 200 to either a center module or a front module. As discussed above with respect to FIG. 1, the segmented lumbar back module 200 can be attached to another module by zipping the two modules together using the zipper 202. The segmented lumbar back module 200 could also be attached to another module or modules via another suitable attachment method.

[0071] In one or more examples, the lumbar support pads 210 can be located such that they provide support for the user of a modular backpack that includes the segmented lumbar back module 200. The lumbar support pads 210 can be constructed via a suitable material that provides cushioning for the user when wearing a modular backpack that includes the segmented lumbar back module 200. For example, the lumbar support pads 210 can include a mesh material that encapsulates a foam material to provide extra cushioning to the lumbar support pads.

[0072] In one or more examples, the lumbar back module 200 can include an armor plate that is stored in a plate pocket 212 when not deployed. The plate pocket 212 can occupy the space adjacent to the lumbar support pads 210 such that when an armor plate is stored in the plate pocket 212, it is located behind the lumbar support pads 210 and does not take up storage space elsewhere. In one or more examples, the armor plate could be stored within a center module of a modular backpack. However, by storing the armor plate in a center module, the armor plate consumes space that could otherwise be used for storing items. Accordingly, by located the armor plate in a plate pocket such as the plate pocket 212 in a back module such as the lumbar back module 200, the armored plate will not use up storage space inside the backpack. The armor plate can be constructed of a material suitable for protecting the user from ballistics such that the armor plate acts as a ballistic shield, as will be discussed further below.

[0073] The straps 208 of the segmented lumbar back module 200 can be constructed of one or more suitable materials that ensure the straps 208 are strong enough to support a substantial amount of weight should the segmented lumbar back module 200 be incorporated into a modular backpack, yet do not add a substantial amount of weight to the modular backpack itself. In one or more examples, the straps 208 can include padding material such that the straps 208 are more comfortable to the user when wearing a modular backpack that includes the segmented lumbar back module 200. In one or more examples, the straps 208 can be adjustable. The straps 208 can include one or more tensionlocks 214 that enable the user to adjust the length of the straps 208 as needed. In one or more examples, the straps 208 can include an additional chest strap that spans between the two straps 208 that can be secured to provide additional security and stability for a modular backpack that includes the segmented lumbar back module 200.

[0074] FIG. 3 illustrates a perspective view of a panel lumbar back module 300 for a modular backpack, in accordance with one or more examples of the disclosure. The panel lumbar back module 300 is an example of another back module that can be used as the back module 106 of the modular backpack 101 of FIG. 1. Thus, in one or more examples, the panel lumbar back module 300 can be one possible back module that is suitable for use in a modular backpack system such as modular backpack system 100. Compared to the segmented lumbar back module 200 of FIG. 2, the panel lumbar back module 300 can include vertical lumbar support pads, rather than segmented lumbar support pads.

[0075] As shown in FIG. 3, the panel lumbar back module 300 can include a zipper 302, a side grab handle 304, a top grab handle 306, straps 308, and lumbar support pads 310. If the panel lumbar back module 300 is incorporated into a modular backpack, the zipper 302 can act as the attachment interface for attaching the panel lumbar back module 300 to either a center module or a front module. As discussed above with respect to FIG. 1, the panel lumbar back module 300 can be attached to another module by zipping the two modules together using the zipper 302. The panel lumbar back module 300 could also be attached to another module or modules via another suitable attachment method.

[0076] In one or more examples, the lumbar support pads 310 can run parallel to one another extending downwards along the panel lumbar back module 300. The lumbar support pads 310 can be located such that they provide support for the user of a modular backpack that includes the panel lumbar back module 300. The lumbar support pads 310 can be constructed via a suitable material that provides cushioning for the user when wearing a modular backpack that includes the panel lumbar back module 300. For example, the lumbar support pads 310 can include a mesh material that encapsulates a foam material to provide extra cushioning for the lumbar support pads.

[0077] In one or more examples, the panel lumbar back module 300 can include an armor plate that is stored in a plate pocket 312 when not deployed. The plate pocket 312 can occupy the space adjacent to the lumbar support pads 310 such that when an armor plate is stored in the plate pocket 312, it is located behind the lumbar support pads 310 and does not take up storage space elsewhere. The armor plate can be constructed of a material suitable for protecting the user from ballistics such that the armor plate acts as a ballistic shield, as will be discussed further below.

[0078] The straps 308 of the panel lumbar back module 300 can be constructed of one or more suitable materials that ensure the straps 308 are strong enough to support a substantial amount of weight should the panel lumbar back module 300 be incorporated into a modular backpack, yet do not add a substantial amount of weight to the modular backpack itself. In one or more examples, the straps 308 can include padding material such that the straps 308 are more comfortable to the user when wearing a modular backpack that includes the panel lumbar back module 300. In one or more examples, the straps 308 can be adjustable. The straps 308 can include one or more tensionlocks 314 that enable the user to adjust the length of the straps 308 as needed. In one or more examples, the straps 308 can include an additional chest strap that spans between the two straps 308 that can be secured to provide additional security and stability for a modular backpack that includes the panel lumbar back module 300.

[0079] FIG. 4 illustrates a perspective view of a panel lumbar back module 400 with a buckle and top pocket 407 for a modular backpack, in accordance with one or more examples of the disclosure. In one or more examples, the panel lumbar back module 400 can be used for the back module 106 of the modular backpack 101 of FIG. 1. Thus, in one or more examples, the panel lumbar back module 400 can be one possible back module that is suitable for use in a modular backpack system such as modular backpack system 100.

[0080] Compared to the panel lumbar back module 300 of FIG. 3, the panel lumbar back module 400 includes a buckle 406 that secures a top pocket 407. As shown in FIG. 4, the top pocket 407 is in a closed position, with the buckle 406 securing the top pocket 407 in the closed position. In one or more examples, the top pocket 407 can be used for storing a number of thin items such as a tablet or laptop. Optionally, the top pocket 407 can be used for storing a dry bag that can quickly and efficiently be deployed and can cover a portion of the modular backpack when deployed to protect the modular backpack from water. When the top pocket 407 is used for storing a dry bag, the dry bag can be fixed to a point within the top pocket 407 and can simply be rolled to store and unrolled to deploy.

[0081] As shown in FIG. 4, the panel lumbar back module 400 includes a zipper 402, a side grab handle 404, straps 408, and lumbar support pads 410. If the panel lumbar back module 400 is incorporated into a modular backpack, the zipper 402 can act as the attachment interface for attaching the panel lumbar back module 400 to either a center module or a front module. As discussed above with respect to FIG. 1, the panel lumbar back module 400 can be attached to another module by zipping the two modules together using the zipper 402. The panel lumbar back module 400 could also be attached to another module or modules via another suitable attachment method.

[0082] In one or more examples, the lumbar support pads 410 can run parallel to one another extending downwards along the panel lumbar back module 400. The lumbar support pads 410 can be located such that they provide adequate support for the user of a modular backpack that includes the panel lumbar back module 400. The lumbar support pads 410 can be constructed via a suitable material that provides adequate cushioning for the user when wearing a modular backpack that includes the panel lumbar back module 400. For example, the lumbar support pads 410 can include a mesh material that encapsulates a foam material to maximize the comfort of the lumbar support pads.

[0083] In one or more examples, the panel lumbar back module 400 can include an armor plate that is stored in a plate pocket 412 when not deployed. The plate pocket 412 can occupy the space adjacent to the lumbar support pads 410 such that when an armor plate is stored in the plate pocket 412, it is located behind the lumbar support pads 410 and does not take up storage space elsewhere. The armor plate can be constructed of a material suitable for protecting the user from ballistics such that the armor plate acts as a ballistic shield, as will be discussed further below.

[0084] The straps 408 of the panel lumbar back module 400 can be constructed of one or more suitable materials that ensure the straps 408 are strong enough to support a substantial amount of weight should the panel lumbar back module 400 be incorporated into a modular backpack, yet do not add a substantial amount of weight to the modular backpack itself. In one or more examples, the straps 408 can include padding material such that the straps 408 are more comfortable to the user when wearing a modular backpack that includes the panel lumbar back module 400. In one or more examples, the straps 408 can be adjustable. The straps 408 can include one or more tensionlocks 414 that enable the user to adjust the length of the straps 408 as needed. In one or more examples, the straps 408 can include an additional chest strap that spans between the two straps 408 that can be secured to provide additional security and stability for a modular backpack that includes the panel lumbar back module 400.

[0085] As discussed above, a modular backpack constructed via the modular backpack system 100 can include any number of center modules. That is, a modular backpack constructed using the modular backpack system 100 can include no center modules, one center module, or multiple center modules, enabling the user to customize their modular backpack as needed. For example, a user could include a modular backpack with one center module sandwiched between a front module and a back module as a daily backpack, or the user could include a number of center modules and use the modular backpack as a travel bag. The center modules of the modular backpack system 100 can be constructed via any combination of suitable materials. For example, the center module can be constructed of nylon, polyester, canvas, polypropylene, etc. In one or more examples, the center module can include a waterproof exterior coating. [0086] FIG. 5 illustrates a perspective view of a clamshell center module 500, in accordance with one or more examples of the disclosure. In one or more examples, the clamshell center module 500 can be used for the center module 104 of the modular backpack 101 of FIG. 1.
