The present application is a continuation-in-part of U.S. application Ser. No. 16/229,851, titled “Backpack Frame” and filed on Dec. 21, 2018. The '851 application is hereby incorporated by reference.
TECHNICAL FIELD OF THE INVENTIONThe present invention relates to wearable personal equipment. Particularly, the invention relates to accessory items for backpacks.
BACKGROUND OF THE INVENTIONFew things can ruin an outdoor adventure (e.g., hiking, biking, etc.) faster than being caught unprepared for any of the numerous problems that thousands of people encounter on such adventures every day. From flats to falls, weather changes to food and water issues, the outdoors are unpredictable for even the most fastidious of planners.
To prepare for the unknown, many nature lovers choose to carry as much gear as reasonable by loading up a backpack with rain-gear, extra clothing, protein bars, first-aid and bike repair kits, and other items. However, many people find backpacks uncomfortable over time. Some even avoid such preparations due to the discomfort caused by carrying a pack for long periods—e.g., sweating, poking, constant point pressure, localized rubbing irritation, and the like.
Until the invention of the present application, these and other problems in the prior art went either unnoticed or unsolved by those skilled in the art. The present invention addresses these issues by providing a backpack frame which performs multiple functions without sacrificing comfort, design, style or affordability.
SUMMARY OF THE INVENTIONThere is disclosed herein a backpack frame assembly which avoids the disadvantages of prior devices while affording additional structural and operating advantages.
Generally speaking, the backpack frame assembly comprises a substantially flat panel configured to be attached to a back area of a backpack, a vented portion configured to allow air to reach a user's back, and a plurality of spacers positioned on the panel to create a gap between the user's back and the backpack.
In an embodiment, the backpack frame assembly further comprises at least one air diverter attached to the panel to divert air into the gap.
The vented panel comprises one of either a rigid plastic panel having a plurality of openings there through, or a mesh material with a rigid peripheral frame.
These and other aspects of the invention may be understood more readily from the following description and the appended drawings.
For the purpose of facilitating an understanding of the subject matter sought to be protected, there are illustrated in the accompanying drawings, embodiments thereof, from an inspection of which, when considered in connection with the following description, the subject matter sought to be protected, its construction and operation, and many of its advantages should be readily understood and appreciated.
While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail at least one preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to any of the specific embodiments illustrated.
As shown in
Referring to
As can be seen in
The first frame portion 14 attaches to the backpack 10 is preferably comprised of a rigid panel 22. The panel 22 allows attachment to the backpack 10 by a number of suitable means, including detachable means, such as straps, snaps, and Velcro® material, and more permanent means, such as rivets, adhesive, or similar devices. One potential method of attaching the backpack 10 to the panel 22 is shown and described in
In an alternate embodiment, as shown in
In another alternate embodiment, as shown in
The vented portion 16 is also preferably comprised of a semi-flexible plastic panel. However, the vented portion 16 should be contoured to fit comfortably against a wearer's back. The vented portion 16 comprises a plurality of openings 28 to allow ventilation which helps prevent excessive sweating of the user's back. The number of openings 28 used should not inhibit the structural integrity of the panel. Cut-out areas at the upper end of the vented portion 16 are intended to accommodate the user's shoulder blades, while a wider middle area effectively spreads the load across the user's back. A slight inward taper at the bottom area, proximate a user's obliques, allows for bending mobility. Top and bottom edges should curve backwards (i.e., away from the user's back) to avoid poking or pinching the user during use. Of course, all corners would be rounded for the same reason.
In an alternate embodiment (not shown), the vented portion 16 may be comprised of a peripheral frame, e.g., a rod-type or bar-type structure, spanned by a mesh or otherwise breathable material.
Finally, the spacer 18 is preferably integral to one of either the first frame portion 14 or the vented portion 16. Preferably, the spacer 18 is comprised of a plurality of leg members 30 positioned about the periphery of the two spaced components. These legs 30 may be integrally molded to at least one of the two above-described panels or completely separate from both. The legs 30 may be solid or hollow, but should provide enough support for a 30 lb backpack without deformation of any kind.
The first frame portion 14 and vented portion 16 may be sized from extra small, for children, to extra-large, for taller users. Preferably, the total length of the frame assembly 12 is within the range of 14-22 inches with a width in the range of 8-20 inches. Larger sizes can be made to accommodate even larger packs, if necessary. Each of the panels for the first frame portion 14 and vented portion 16 should have a thickness of from about 0.1 to about 0.8 inch, preferably about 0.25 inch, and the spacer 18 should be in the range of 0.5 to 2.0 inches, preferably 1.5 inches. Accordingly, the depth (i.e., front to back) of the frame assembly 12 would preferably fall in the range of from about 0.7 inch to about 3.6 inches, with 1.5 inches being most preferred.
The gap or channel 20 formed between the two panels, 14 and 16, is preferably about one inch. This feature is designed to collect air from the sides of the frame 12 and push it towards the center before exiting out the bottom. The ventilation holes 28 allow the airflow to contact the user's back removing heat and adding cooling/evaporative properties when contacting moist/perspiring surfaces. The channel 20 could be equipped with additional features for personalization or improved performance, such as trim lighting or a battery powered fan to increase airflow into the channel 20.
As shown in
It should also be appreciated that while
Performance and structural integrity variations of the frame assembly 12 could be made with by changing materials or geometries of the components. The use of metals, high-density plastics or other durable synthetics could provide greater impact resistance. For example, a Kevlar (or Kevlar-like) material used for the vented portion 16 could impart some bullet-resistant properties to the frame assembly 12 for military or law enforcement applications. Another example includes the use of a deforming spacer 20 to absorb impact forces in the event a user lands on their back at high-speed.
Attachment accessories could also be added to the frame assembly 12 to direct airflow upwards, underneath clothing of the user to aid in dissipating the heat at its source, i.e., the user's back. For example, a thin, flat tube (e.g., as shown in
In an alternate embodiment, a one-piece frame 212 is shown in
The single-piece frame 212 includes a substantially flat panel 214 having raised spacer elements 216 and a plurality of ventilation openings 218. The spacer elements 216 can be designed in any of numerous shapes and/or dimensions, including squares, circles, cones, arcs, ridges, etc. As shown, the spacer elements 216 preferably have a curved profile to direct air across and down the user's back.
In use, the panel surface with the raised spacer elements 216 is worn facing the user's back while the opposite surface of the flat panel 214 will meet the backpack.
Preferably, the backpack frame 212 will be made from a material that can hold and return to its original shape but provides flexibility to contour to the user's back and to absorb the shock of a backpack bouncing while in motion. Many polymer and polymer blend materials known to those skilled in the art would be suitable for molding the flat panel 214.
As shown in
In an alternate embodiment, the frame 212 can be integral to the backpack—i.e., permanently attached via rivets (or similar fasteners) or as part of the back panel of a backpack.
Along the sides of the frame 214, detachable air diverters (winglets) 220 help direct more air into the frame to aid in cooling. The air diverters 220 can also accommodate additional accessories such as lighting or color flourishes (not shown).
The disclosed frame 212 has additional uses as well. For example, the frame 212 could be worn under heavy outer garments to create the described cooling air gap. Some examples include use under (1) a video rig worn by a video production professional to both facilitate cooling and distribute load; (2) a protective garment such as a bullet proof vest worn by military, security and law enforcement professionals; and (3) oxygen tanks and/or other firefighting gear worn by fire professionals.
The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While particular embodiments have been shown and described, it will be apparent to those skilled in the art that minor changes and modifications may be made without departing from the broader aspects of applicants' contribution. The actual scope of the protection sought is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
