Definitions
- This 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.
- Backpacks 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.
- 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.
- the 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.
- 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.
- a user may use a very specialized pack for a wider range of activities.
- 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.
- 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.

- the attachment fixtures 140 c 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.
- 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 FIGS. 1 and 2 discussed above if a user desires a more lightweight version of the apparatus or plans to use the apparatus with a backpack that already has satisfactory hip and/or shoulder straps.
- 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.
- 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.
- FIG. 4 is a side view of a user wearing the backpack 200 coupled with the backpack frame insert 100 (e.g., apparatus 100 ).

Description
- 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.
- This 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.
- Backpacks 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.
- The 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.

FIG. 1 is a perspective view of a first embodiment of an exemplary backpack frame insert 100 (also referred to as asuspension apparatus 100 or apparatus 100) that may be used with any backpack. Theapparatus 100 may include 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 details of an example structure are discussed below. For example, theapparatus 100 may include aframe 110 and afront suspension 120 suspended between elements of theframe 110. Theapparatus 100 may also include aback panel 130, and one ormore attachment fixtures - 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 theapparatus 100. Theframe 110 may include anelement 111 that spans a distance in the roughly vertical direction, one ormore elements more elements elements elements elements elements frame 110 may be made of an integral single piece), or may be an assembly of a plurality of pieces (e.g., theframe 110 may be an assembly of a plurality of pieces 111-113 d) connected together by any suitable connection means, such as welding, screws, bolts, nuts, clamps, etc. - The
front suspension 120 may be attached to theframe 110. Thefront suspension 120 may include amaterial 121. Thematerial 121 may be suspended between elements of theframe 110. Thematerial 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 thematerial 121 to a second side of the material 121). Thebreathable material 121 may therefore increase the ventilation of theapparatus 100 when theapparatus 100 is used by a user to carry a backpack (e.g., when theapparatus 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 moresuitable attachment mechanisms attachment mechanisms attachment loops attachment mechanisms attachment mechanisms attachment mechanisms - Attaching the
front suspension 120 to one or more of theprotrusions FIG. 1 may create a space between thefront suspension 120 and other frame elements such as 111, 112 a, and 112 b. The space may further improve ventilation when theapparatus 100 is used by the user to carry a backpack (e.g., when theapparatus 100 is disposed between a back of the user and the backpack). When theapparatus 100 is disposed between a back of the user and a backpack, the user's back may be separated from the backpack and may not directly touch the back facing side of the backpack, thereby providing a breathable space for the user's back. - The
material 121 included in thefront suspension 120 may include aconstriction 123 in the middle portion of theapparatus 100, which may allow straps from a backpack to be pulled through theapparatus 100. Agap 124 may be present between theelement 113 d 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 113 c and 113 d as well. Thefront suspension 120 may includeattachment fixtures apparatus 100 to a backpack. For example, theframe 110 may be releasably, detachably, or removably coupled, affixed, or attached to the backpack through theattachment fixtures attachment fixtures apparatus 100 is used to carry a backpack. When theattachment fixtures apparatus 100 may be detached or released from the backpack. - The
apparatus 100 may be used with different backpacks. For example, theapparatus 100 may be detached (or removed, released) from a first backpack and attached (or affixed, coupled) to a second backpack. Thus, theattachment fixtures apparatus 100 from the backpack, and quick switch from one backpack to another. - The
back panel 130 may include amaterial 131 to which one ormore attachment mechanisms 132 may be attached. Theattachment mechanisms 132 may be similar to, the same as, or different from theattachment mechanisms 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 theback panel 130. Theattachment mechanisms 132 may attach to one ormore straps 125 attached to thefront suspension 120. By tightening one or more of thestraps 125 through the use of one or more of theattachment mechanisms 132, tension may be placed on thefront suspension 120 as well as theback panel 130. In some embodiments, one or more of thestraps 125 may also attach directly to theframe 110 rather than to theback panel 130 with any suitable attachment mechanisms (e.g., 122 a, 122 b, 122 c, and 132) discussed above. In some embodiments, thefront suspension 120 may be attached directly to theback panel 130 without any attachment mechanisms (e.g., 122 a, 122 b, 122 c, or 132). Theback panel 130 may include theattachment fixtures 140 for coupling theapparatus 100 to a backpack. Thematerial 131 may be suspended between the elements of theframe 110 through theattachment mechanisms 132 and/or thestraps 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). -
FIG. 2 is a perspective view of the breathable apparatus 100 (i.e., the backpack frame insert 100) coupled to abackpack 200. The geometry ofapparatus 100 creates agap 101 between theframe 110 and theback panel 130. The geometry of thefront suspension 120 may also be cut in such that it is narrower in the middle portion of theapparatus 100, as described above with respect to theconstriction 123 shown inFIG. 1 . These geometric features allowshoulder straps 220 of thebackpack 200 to be pulled directly through theframe 100 such that theshoulder straps 220 rest to the inside of theframe 110, and to the outside of theback panel 130 as well as thefront suspension 120. - The
apparatus 100 depicted inFIGS. 1 and 2 is only one example embodiment of the various ways that a removable, breathablebackpack suspension apparatus 100 may be constructed. Other embodiments are contemplated. For example, in some embodiments, theframe 110 may be narrowed (e.g.,frame 110 may include a constriction) in the middle portion of theapparatus 100 such that thegap 101 is small or nonexistant, in which case theshoulder straps 220 of thebackpack 200 may rest to the outside of theback panel 130, theframe 110, and/or thefront suspension 120. In some embodiments, a constriction in theframe 110 and/or thefront suspension 120 may not be utilized at all, in which case theshoulder straps 220 of thebackpack 200 may travel over theapparatus 100 in the vertical direction instead of through theapparatus 100. In some embodiments, the bottom portions of theshoulder straps 220 of thebackpack 200 may be decoupled from the top portions of theshoulder straps 220, pulled through theapparatus 100, then recoupled. In some embodiments, one or more portions of thefront suspension 120 may be decoupled from thefront suspension 120, theframe 110, and/or any other portion of theapparatus 100 until theshoulder straps 220 of thebackpack 200 are pulled through, at which point these portions may be recoupled. - A plurality of
attachment fixtures apparatus 100 with thebackpack 200. For example, theattachment fixtures frame 110 to theshoulder straps 220 of thebackpack 200. Theattachment fixtures shoulder straps 220 to theapparatus 100, such as, for example, to theframe 110. Theattachment fixture 140 a shown inFIG. 2 may be affixed to the upper portion of ashoulder strap 220. More than oneattachment fixture 140 a may be included, for example, one on each side of theapparatus 100 for eachshoulder strap 220. The upper portion of the frame 110 (and hence the apparatus 100) may rest on the upper portions of the shoulder straps 220. Theattachment fixture 140 b may be affixed to the lower portion of ashoulder strap 220, or to awebbing material 221 employed in thebackpack 200 for tightening thestraps 220. More than oneattachment fixture 140 b may be included, for example, one on each side theapparatus 100 for eachshoulder strap 220. Themain pack body 210 of thebackpack 200 may include a back facing side that is in contact with theback panel 130, as well as one or more elements of theframe 110. t In some embodiments, the width of theframe 110 may be smaller than the width of thebackpack 200. In such embodiments, thebackpack 200 may rest on theframe 110 rather than passing through theframe 110 to touch the back of the user. Thus, theframe 110 may substantially prevent thebackpack 200 from touching the back of the user. In some embodiments, the width of theframe 110 may be greater than the width of thebackpack 200. In such embodiments, theback panel 130 may be coupled with theframe 110 to prevent thebackpack 200 from passing through theframe 110 and touching the back of the user. Theframe 110 and theback panel 130 may hold themain pack body 210 away from thefront suspension 120. -
FIG. 3 is a perspective view of a second embodiment of the backpack frame insert 100 (e.g., apparatus 100) that includes shoulder and hip straps coupled with thebackpack 200. Theapparatus 100 shown inFIG. 3 may include any feature of theapparatus 100 depicted inFIGS. 1 and 2 and discussed above. InFIG. 3 , theapparatus 100 is shown to include one ormore straps 150. Thestraps 150 may include one ormore hip straps 152 attached to theframe 110, thefront suspension 120, theback panel 130, and/or any combination of these items. The hip straps 152 may be attached fixedly or removably to the rest of the apparatus 100 (e.g., the frame 110). For example, the hip straps 152 may utilize attachment mechanisms (e.g., any attachment mechanisms discussed above) that may allow thestraps 152 to be released from and/or loosened from the rest of the apparatus 100 (e.g., the frame 110). In some embodiments, the hip straps 152 may include a continuous loop with both ends pulled through thehip strap gaps 124 described inFIG. 1 . In some embodiments, the hip straps 152 may includedevices straps 152 around a user. - The
straps 150 may also include one ormore shoulder straps 151 that may be attached to theframe 110, thesuspension 120, theback 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. Theapparatus 100 may include astructure 153 on each side that may function as an attachment point between theback panel 130 and theframe 110 to which ashoulder strap 151 may be attached. As shown inFIG. 3 , theframe 110 may be coupled (or attached, affixed) to theshoulder straps 151 through thestructure 153. Thestructure 153 may include one end having a hole slidably coupled to theframe 110, and another end coupled to theback panel 130 and/or the opposite side of theframe 110. In some embodiments, the one end slidably coupled to theframe 110 may alternatively be fixed at a place on theframe 110. In some embodiments, thestructures 153 may rest over the shoulder straps 151. In some embodiments, theshoulder straps 151 may be attached to the bottom, the front, the top, or any other portion of thestructures 153. In some embodiments, thestructures 153 may be an extension piece of the shoulder straps 151. In such embodiments, theshoulder straps 151 include thestructures 153 to allow theshoulder straps 151 to be attached to at least one of theframe 110, thefront suspension 120, and theback panel 130. In some embodiments, theshoulder straps 151 may be releasably (or removably, detachably) coupled to thestructures 153 through a suitable attachment mechanism (e.g., any attachment mechanism discussed above) such that theshoulder straps 151 may be removed and/or reattached. - 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 asecond device 157 that may include a strap and an attachment mechanism to connect afirst shoulder strap 151 to asecond shoulder strap 151. Thesecond device 157 may be worn across a user's sternum or thereabouts. In the embodiments where theapparatus 100 includesshoulder straps 151, thebackpack 200 may have itsown shoulder straps 220 attached to theapparatus 100 rather than worn around a user. This may be achieved by running thestraps 220 of thebackpack 200 around thehorizontal elements 112 a of theframe 110. When theapparatus 100 is used to carry thebackpack 200, theframe 110 may be held between a back of the user and thebackpack 200 by various devices or structures discussed above, such as, for example, one or more of thestructures 153, theattachment fixtures 140 a, theshoulder straps 151, and/or theshoulder straps 220, etc. - Additionally attachment fixtures may be included in the
apparatus 100 to hold thebackpack 200 and theapparatus 100 together. For example, one ormore attachment fixtures 140 c may be attached to theframe 110, thefront suspension 120, and/or theback panel 130, and may be placed in such a way as to circumscribe themain pack body 210 of thebackpack 200. The one ormore attachment fixtures 140 c 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 thepack body 210 with the one ormore attachment fixtures 140 c, thebackpack 200 may be securely attached to theapparatus 100. In some embodiments, theattachment fixtures 140 c may be attached to theshoulder straps 220 of thebackpack 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. Theapparatus 100 may achieve that same goal on a backpack which lacks rigidity and hip straps, by adding pack structure with theframe 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 theframe 110 to facilitate the assembly and/or disassembly of theframe 110. Thestructures 115 may include a telescoping slip fit utilized in collapsible tent poles and the like (hereinafter thestructures 115 may also be referred to as the telescoping frame sections 115). Thestructures 115 that allow theframe 110 to be compactly collapsed or disassembled may be desirable if theapparatus 100 is to be collapsed and packed away into thebackpack 200 when thebackpack 200 is to be used over certain terrains or whenever a closer center of gravity might be desirable. By loosening the tension in thematerial 121 of thefront suspension 120 and/or thematerial 131 of theback panel 130, thetelescoping frame sections 115 may be pulled apart to disassemble theapparatus 100, and then later put back together to re-assemble theapparatus 100 by increasing the tension in thematerial 121 of thefront suspension 120 and/or thematerial 131 of theback panel 130. - Attachment mechanisms such as 154 may couple the
straps 150 to theapparatus 100. These mechanisms may be utilized onhip straps 152,shoulder straps 151 and any combination thereof. These attachment mechanisms may be utilized to releasably (or detachably, removably) couple (or affix, attach) thestraps 150 with theapparatus 100. This may allow the embodiment described herein to be altered by a user such that it is more similar to the embodiment described inFIGS. 1 and 2 discussed above if a user desires a more lightweight version of the apparatus or plans to use the apparatus with a backpack that already has satisfactory hip and/or shoulder straps. - The
apparatus 100 may also be utilized to carry a pannier and other containers that may be affixed or attached to theframe 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 theapparatus 100, these uncomfortable features need not touch the user's back. Additionally, theframe 110 of theapparatus 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. -
