This application is a continuation of international application no. PCT/US2015/014037, filed Feb. 2, 2015, which claims the benefit of priority to U.S. Provisional Patent Application No. 61/935,333, filed Feb. 4, 2014, entitled “Breathable Backpack Frame Insert.” The entire contents of the aforementioned international and provisional applications are incorporated herein by reference.
FIELDThis disclosure relates to backpacks, and more particularly to a backpack frame insert which may be added to a backpack to increase the comfort of the backpack by providing improved ventilation, support, and padding.
BACKGROUNDBackpacks may be as simple as a pack for holding items, and straps used to hold the pack onto the body of a user. Many backpacks use foam padding on the straps and the portion of the pack which faces the back of the user to increase the comfort of the backpack when carried by the user. A common discomfort experienced when wearing a backpack is that the lack of breathability of the shoulder straps and back padding traps the user's perspiration, thereby creating a damp user experience. Some examples of the backpacks are disclosed in U.S. Pat. No. 8,579,171 to Gleason et al., U.S. Patent Application Publication Nos. 2013/0206805 to Kim et al., 2012/0199624 to Howell, and 2012/0012629 to Buffington.
Some backpacks employ materials with increased breathability to increase the circulation of air to a user and decrease the dampness created by wearing the backpack. One such backpack utilizes a porous mesh-like material which is held in suspension by a frame to create an air space between the back of the user and the backpack body. Another backpack uses foams that have a varying topography and perforations to allow the circulation of air to the body of the user. These types of backpack architectures can be successful in increasing pack breathability. However to enjoy this level of breathability, a user is limited to a specific subset of backpacks and the specific set of features offered with those particular backpacks.
In addition to ventilation, some backpacks lack comfort in the areas of support and padding. Insufficient support can cause user fatigue when wearing a backpack, and insufficient padding can cause pressure points which irritate a user when wearing a backpack.
SUMMARYThe backpack frame insert described herein allows a user to enjoy improved comfort on any backpack. The backpack frame insert may be integrated with all backpacks, even if those backpacks were not originally designed to be used with the backpack frame insert. A user who has multiple backpacks may integrate the backpack frame insert with any of those backpacks to make wearing the backpack more comfortable. For example, a user who owns a backpack that is highly specialized to be ideal in a particular activity where breathability is not a top priority may wish to use that backpack in other activities where breathability is a top priority. With the use of the disclosed interchangeable and breathable backpack frame insert, a user may use a very specialized pack for a wider range of activities.
Similar to how a backpack rain cover can allow any backpack to be used successfully in wet conditions, certain embodiments of the backpack frame insert may be used to allow any backpack to be used successfully in conditions which would cause a user to perspire. Additionally, certain embodiments of the backpack frame insert may allow an ultra light backpack with minimal support to be worn comfortably with heavier loads due to increased padding and support.
An embodiment relates to a backpack suspension apparatus. The backpack suspension apparatus includes a frame, a material suspended between elements of the frame, and means for releasably holding the frame between a back of a user and a backpack.
Another embodiment relates to a backpack apparatus. The backpack apparatus includes a padded material and means for releasably holding the padded material between a user and a backpack. The padded material is disposed between a back of the user and a back facing panel of the backpack.
Another embodiment relates to a method for increasing the comfort of a backpack. The method includes placing a backpack frame insert having a structure and a breathable material coupled to the structure between a user and a backpack.
Another embodiment relates to an apparatus. The apparatus includes a structure configured to be removably attached to and detached from a backpack and disposed between a back of a user and the backpack.
The accompanying drawings, which are incorporated herein and constitute part of this specification, illustrate examples of the disclosed devices and methods, and together with the general description given above and the detailed description given below, serve to explain the features of the invention.
The frame 110 may be a rigid or semi-rigid frame, which may include one or more tubes made of a suitable material, such as, for example, aluminum, composites such as carbon fiber, polymers such as high density polyethylene, and any other suitable material which provides structure to the apparatus 100. The frame 110 may include an element 111 that spans a distance in the roughly vertical direction, one or more elements 112a and 112b that span a distance in the roughly horizontal direction, and one or more elements 113a, 113b, 113c, and 113d that create protrusions from these elements 111, 112a, and 112b (hereinafter elements 113a, 113b, 113c, and 113d may also be referred to as protrusions). One or more of elements 111, 112a, 112b, and 113a-113d may include a tube discussed above. The elements 111, 112a, 112b, and 113a-113d may be made of an integral single piece (e.g., the frame 110 may be made of an integral single piece), or may be an assembly of a plurality of pieces (e.g., the frame 110 may be an assembly of a plurality of pieces 111-113d) connected together by any suitable connection means, such as welding, screws, bolts, nuts, clamps, etc.
The front suspension 120 may be attached to the frame 110. The front suspension 120 may include a material 121. The material 121 may be suspended between elements of the frame 110. The material 121 may be a breathable material, such as, for example, a lightweight fabric, a mesh, synthetic and natural fibers such as polyester, nylon, cotton, or any other material that allows fluid media to pass through (e.g., to pass from a first side of the material 121 to a second side of the material 121). The breathable material 121 may therefore increase the ventilation of the apparatus 100 when the apparatus 100 is used by a user to carry a backpack (e.g., when the apparatus 100 is disposed between a back of the user and the backpack). Fluid media may include gaseous as well as liquid media such as air, vaporous perspiration, liquid perspiration, and the like.
The front suspension 120 (which includes the material 121) may be removably (or detachably or releasably) affixed or attached to the frame 110 in at least one place through the use of one or more suitable attachment mechanisms 122a, 122b, and 122c. In some embodiments, one or more of the attachment mechanisms 122a, 122b, and 122c may include attachment loops 122a, 122b, and 122c. In some embodiments, one or more of the attachment mechanisms 122a, 122b, and 122c may include other suitable attachment means. For example, one or more of the attachment mechanisms 122a, 122b, and 122c may include an adjusting mechanism that allows a strap or cord to be tightened and loosened, a coupling mechanism that allows a strap or cord to be attached and detached, and/or an adjustable coupling mechanism that allows a strap or cord to be attached and detached as well as tightened and loosened. In some embodiments, one or more of the attachment mechanisms 122a, 122b, and 122c may include ladder lock buckles, three bar slides, line tensioners, side release buckles, front release buckles, belt style buckles, hook and loop closures, cords to be tied together, and the like.
Attaching the front suspension 120 to one or more of the protrusions 113a, 113b, 113c, and 113d as shown in
The material 121 included in the front suspension 120 may include a constriction 123 in the middle portion of the apparatus 100, which may allow straps from a backpack to be pulled through the apparatus 100. A gap 124 may be present between the element 113d and the material 121 to allow hip straps from a backpack to be pulled through and worn around the user. In some embodiments, hip straps from a backpack may be worn to the outside of frame elements such as 113c and 113d as well. The front suspension 120 may include attachment fixtures 140a and 140b for releasably, detachably, or removably coupling, affixing, or attaching the apparatus 100 to a backpack. For example, the frame 110 may be releasably, detachably, or removably coupled, affixed, or attached to the backpack through the attachment fixtures 140a and 140b. The attachment fixtures 140a and 140b may hold the frame 110 (and thereby the apparatus 100) between a back of a user and a backpack, when the apparatus 100 is used to carry a backpack. When the attachment fixtures 140a and 140b are removed, detached, or released from the backpack, the apparatus 100 may be detached or released from the backpack.
The apparatus 100 may be used with different backpacks. For example, the apparatus 100 may be detached (or removed, released) from a first backpack and attached (or affixed, coupled) to a second backpack. Thus, the attachment fixtures 140a and 140b may enable easy assembly and disassembly of the apparatus 100 from the backpack, and quick switch from one backpack to another.
The back panel 130 may include a material 131 to which one or more attachment mechanisms 132 may be attached. The attachment mechanisms 132 may be similar to, the same as, or different from the attachment mechanisms 122a, 122b, and 122c discussed above. The material 131 may be comprised of any suitable materials, such as, for example, textile materials such as nylon and polyester, and/or any other material that may withstand the tension applied to the back panel 130. The attachment mechanisms 132 may attach to one or more straps 125 attached to the front suspension 120. By tightening one or more of the straps 125 through the use of one or more of the attachment mechanisms 132, tension may be placed on the front suspension 120 as well as the back panel 130. In some embodiments, one or more of the straps 125 may also attach directly to the frame 110 rather than to the back panel 130 with any suitable attachment mechanisms (e.g., 122a, 122b, 122c, and 132) discussed above. In some embodiments, the front suspension 120 may be attached directly to the back panel 130 without any attachment mechanisms (e.g., 122a, 122b, 122c, or 132). The back panel 130 may include the attachment fixtures 140 for coupling the apparatus 100 to a backpack. The material 131 may be suspended between the elements of the frame 110 through the attachment mechanisms 132 and/or the straps 125. The material 121 (e.g., first material 121) is closer to the user's back than the material 131 (e.g., second material 131).
The apparatus 100 depicted in
A plurality of attachment fixtures 140a and 140b may be employed to releasably (or detachably, removably) couple (or affix, attach) the apparatus 100 with the backpack 200. For example, the attachment fixtures 140a and 140b may releasably (or detachably, removably) couple (or affix, attach) the frame 110 to the shoulder straps 220 of the backpack 200. The attachment fixtures 140a and 140b may both couple the shoulder straps 220 to the apparatus 100, such as, for example, to the frame 110. The attachment fixture 140a shown in
The straps 150 may also include one or more shoulder straps 151 that may be attached to the frame 110, the suspension 120, the back panel 130, and/or any combination of these items, through the use of attachment mechanisms (e.g., any attachment mechanism discussed above) or may be attached directly to one or more of these items. The apparatus 100 may include a structure 153 on each side that may function as an attachment point between the back panel 130 and the frame 110 to which a shoulder strap 151 may be attached. As shown in
The shoulder straps 151 may include a first device 155 that may function as an attachment mechanism allowing attachment and adjustment of the shoulder straps 151. The shoulder straps 151 may include a second device 157 that may include a strap and an attachment mechanism to connect a first shoulder strap 151 to a second shoulder strap 151. The second device 157 may be worn across a user's sternum or thereabouts. In the embodiments where the apparatus 100 includes shoulder straps 151, the backpack 200 may have its own shoulder straps 220 attached to the apparatus 100 rather than worn around a user. This may be achieved by running the straps 220 of the backpack 200 around the horizontal elements 112a of the frame 110. When the apparatus 100 is used to carry the backpack 200, the frame 110 may be held between a back of the user and the backpack 200 by various devices or structures discussed above, such as, for example, one or more of the structures 153, the attachment fixtures 140a, the shoulder straps 151, and/or the shoulder straps 220, etc.
Additionally attachment fixtures may be included in the apparatus 100 to hold the backpack 200 and the apparatus 100 together. For example, one or more attachment fixtures 140c may be attached to the frame 110, the front suspension 120, and/or the back panel 130, and may be placed in such a way as to circumscribe the main pack body 210 of the backpack 200. The one or more attachment fixtures 140c may utilize any attachment mechanism as described above and may be comprised of a flexible strap material such as nylon webbing and the like. By circumscribing the pack body 210 with the one or more attachment fixtures 140c, the backpack 200 may be securely attached to the apparatus 100. In some embodiments, the attachment fixtures 140c may be attached to the shoulder straps 220 of the backpack 200.
The apparatus 100 may be utilized to increase the comfort of the backpack as experienced through increased ventilation, increased padding, and increased support. Many backpacks utilize a rigid or semi-rigid frame in conjunction with hip straps to transfer some of a backpacks weight from a user's shoulders to the user's hips. The apparatus 100 may achieve that same goal on a backpack which lacks rigidity and hip straps, by adding pack structure with the frame 110, and by transferring some of the load to the user's hips through the use of hip straps 152, thereby allowing that backpack to comfortably carry a greater load.
A plurality of structures 115 may be included on the frame 110 to facilitate the assembly and/or disassembly of the frame 110. The structures 115 may include a telescoping slip fit utilized in collapsible tent poles and the like (hereinafter the structures 115 may also be referred to as the telescoping frame sections 115). The structures 115 that allow the frame 110 to be compactly collapsed or disassembled may be desirable if the apparatus 100 is to be collapsed and packed away into the backpack 200 when the backpack 200 is to be used over certain terrains or whenever a closer center of gravity might be desirable. By loosening the tension in the material 121 of the front suspension 120 and/or the material 131 of the back panel 130, the telescoping frame sections 115 may be pulled apart to disassemble the apparatus 100, and then later put back together to re-assemble the apparatus 100 by increasing the tension in the material 121 of the front suspension 120 and/or the material 131 of the back panel 130.
Attachment mechanisms such as 154 may couple the straps 150 to the apparatus 100. These mechanisms may be utilized on hip straps 152, shoulder straps 151 and any combination thereof. These attachment mechanisms may be utilized to releasably (or detachably, removably) couple (or affix, attach) the straps 150 with the apparatus 100. This may allow the embodiment described herein to be altered by a user such that it is more similar to the embodiment described in
The apparatus 100 may also be utilized to carry a pannier and other containers that may be affixed or attached to the frame 110. Many bicycle panniers utilize a rigid panel with hooks for attaching the pannier to the rack mounted on a bicycle. That hard surface with protrusions such as hooks may be uncomfortable to carry on one's back, but with the space created between the user and the pannier by the apparatus 100, these uncomfortable features need not touch the user's back. Additionally, the frame 110 of the apparatus 100 may provide a similar attachment structure to the attachment structure on a bicycle rack that is used when attaching the pannier to a bicycle.
In some embodiments, the apparatus 100 may be coupled to the backpack 200 through the use of attachment fixtures 140 (which may include 140a, 140b as exemplarily shown in
Since the apparatus 100 may be worn sandwiched between the backpack 200 and the user 300, the attachment fixtures 140a and 140b may not be necessary for successful operation of the apparatus 100. These attachment fixtures 140a and 140b may be used for aligning the backpack 200 with the apparatus 100, as well as coupling the apparatus 100 and the backpack 200 when not being worn by the user 300.
The attachment fixtures 140 described by
The back panel 440, the shoulder panels 420a and 420b, and the hip panels 430 may or may not be connected to one another. In some embodiments, the back panel 440, the shoulder panels 420a and 420b, and the hip panels 430 are connected to one another. In such embodiments, they may be attached directly to one another and/or through the use of an attachment mechanism as described above to allow for adjustment and removable coupling of these panels/portions from one another. In the embodiment shown in
The apparatus 400 may be attached to the backpack 200 through various attachment fixtures. For example, one or more attachment fixtures 415a, 415b, 415c, 415d, 415e, and 415f may be included in the apparatus 400. The attachment fixtures 415a, 415b, 415c, 415d, 415e, and 415f may be configured to removably (or detachably, releasably) fasten (or attach, affix, connect) the apparatus 400 (e.g., the padded material 411 and/or the back panel 440) to the shoulder straps 220 and/or the hip panels 430 of the backpack 200. These attachment fixtures 415a, 415b, 415c, 415d, 415e, and 415f may be affixed to the shoulder panels 420, the hip panels 430, the back panel 440, and/or any combination of these panels. In some embodiments, the attachment fixtures 415a, 415b, and 415c are attached to the back panel 440 as in 415a, 415b, 415c, and attachment fixtures 415d, 415e, and 415f are attached to the shoulder panels 420a and 420b, while no attachment fixtures 415a, 415b, 415c, 415d, 415e, or 415f are shown on the hip panels 430. In some embodiments, the attachment fixtures 415a, 415b, and 415c may be attached to the padded material 411 to releasably hold the padded material between a user and a backpack.
The attachment fixtures 415a, 415b, 415c, 415d, 415e, and 415f may utilize a wide range of attachment mechanisms, such as any suitable attachment mechanism described above. In some embodiments, the apparatus 400 may be attached to the backpack 200 through the use of one or more straps 416, which are affixed to the back panel 440 and circumscribes the main pack body 210. The straps 416 may be similar to or different from the attachment fixture 140c described above in connection with
The panel 440 may include a panel 412 that may be rigid or semi-rigid. The panel 412 may include a polymer material such as high density polyethylene, a metal such as aluminum, a composite such as carbon fiber, and/or any other suitable material that may add rigidity to the apparatus 400. The level of rigidity of the panel 412 may be increased or decreased by various means, such as, for example, by choosing a more or less rigid material composition, combining various materials, and changing the geometry of the panel 412. Such geometric changes may include, but are not limited to, changing thickness, and including ridges.
The apparatus 400 may have varied thicknesses to reduce the volume specific weight, to increase the padding softness, and/or to increase ventilation as experienced by a user. The varied thicknesses may be created by the padded material 411, the more rigid panel 412, or any combination of the padded material 411 and the panel 412. The varied thicknesses may be achieved by including in the apparatus 400 a plurality of protrusions 413a and 413b, which extend toward a user from the average thickness of apparatus 400. In some embodiments, the panel 440 may include a plurality of voids or cavities 414a that may reduce the proximity of the padded material 411 to a user's body. The voids 414a may create holes that permeate or extend throughout the entirety of the thickness of the apparatus 400. The voids 414a may create divots and channels of decreased thickness in the apparatus 400. The varied thicknesses of the apparatus 400 achieved through the use of protrusions 413a and 413b, and voids 414a may increase the circulation of fluid media such as air and perspiration present at the interface between the apparatus 400 and the user.
The hip panels 430 and/or the shoulder panels 420a and 420b may also include voids. For example, as shown in
In some embodiments, the panel 412, the padded material 411, and the protrusions 413a and 413b may be arranged in such an order that the panel 412 is closest to the backpack 200, and the protrusions 413a and 413b are closest to the user, and the padded material 411 is sandwiched between the panel 412 and the protrusions 413a and 413b. The order in which these elements are arranged may be different. For example, the padded material 411 may switch its position with the panel 412 and/or the protrusions 413a and 413b.
The apparatus 400 may employ a wide range of covering materials such as meshes and light fabrics that may be disposed between the furthest padded material 411 of the apparatus 400 and a user's body.
