Abstract
A hip belt (100) is disclosed having split left (130) and right (150) portions. The upper legs (131, 151) and lower legs (132,152) of the split portions are attached to adjustable straps (180, 184) such that the belt tension is distributed to both the upper and lower portions to facilitate a snug fit to the user. Transverse members (200) interconnect the respective upper and lower legs, maintaining the desired leg spacing. The transverse members are semi-rigid, flexible members, allowing the split belt to readily conform to the user's profile. Fastening the transverse members along the outer edges of the belt permits the legs to rotate to better conform to the user. In an embodiment of the hip belt (300) a plurality of transverse members are distributed along the length of the split portion of the belt.
Description




FIELD OF THE INVENTION




The present invention relates to the field of backpacks, and in particular, to hip belts for backpacks.




BACKGROUND OF THE INVENTION




Conventional backpacks and similar load carrying devices are well known and in widespread use around the world. Wilderness hikers and backpackers, cross country skiers, hunters, and other outdoors enthusiasts almost invariably pack the necessities and niceties for their activities into a backpack typically having a pair of shoulder straps that permit the packed gear to be carried adjacent the users back. Special-purpose devices, have also been developed to enable individuals to more easily transport other equipment, for example, for portage of watercraft and the like. Backpacks have also found uses other than for sports-related activities, for example as a convenient form of luggage for travelers, and for carrying books, electronic gear, military equipment, and the like. The term “backpack,” as used herein, should be understood to encompass all of these various load-carrying devices.




In many prior art backpacks, the pair of shoulder straps provide the only support elements for supporting the backpack on the user. This configuration, however, has been found to put undue and uncomfortable stresses on the user's back and shoulders. With the weight of the backpack centered behind the upright user, the user's shoulders are pulled backwards, which can become uncomfortable, and even result in injury to the user. Moreover, the walking motion can cause the backpack to sway back and forth and forward and backward, in some instances causing the lower portion of the backpack to repetitively bump into the user's torso, and causing the weight of the backpack to repeatedly shift away from the user. This can add to the discomfort of carrying even a relatively light backpack, particularly when carrying heavy loads and/or over several hours of hiking.




Most modern backpacks that are intended for carrying significant weight and/or for long times, therefore, include a hip belt or similar apparatus that attaches the backpack to the user's hips, usually near the lower end of the backpack. The hip belt provides several benefits. The hip belt transfers a portion of the backpack weight to the user's hips, relieving stress on the user's shoulders and back. It generally fixes the lower portion of the backpack next to the user, virtually eliminating swaying, and keeping the weight of the backpack close to the user.




Although the addition of a hip belt represents an improvement over backpacks having only shoulder straps, the hip belt itself can become uncomfortable. The hip belt is typically quite wide in order to distribute the load over a large area. In such prior art belts, however, the flexibility of the belt tends to result in concentrating the load in a fairly narrow region near the centerline of the hip belt, which is not optimal for user comfort. Moreover, the relatively large area over which the belt is located can become hot due to stress, friction, and lack of ventilation. Some prior art hip belts have attempted to overcome this problem by splitting the hip belt along a portion of its length. This split belt configuration provides two relatively narrow belts (for a portion of the belt length) rather than a singlewide belt, thereby improving ventilation and user comfort. In use, however, the split portions, or legs, of these split hip belt designs have a tendency to either spread apart more than is desired, resulting in one leg of the split belt carrying essentially the entire load, or coming together, thereby eliminating much of the benefit of the split belt design. There is therefore a need for an improved hip belt that is comfortable to the user, beneficially spreads the load, and improves ventilation around the belt.




SUMMARY OF THE INVENTION




It is an object of the present invention to provide a hip belt for transferring a portion of a carried load to a user's hips that is comfortable to the user.




It is a further object of the present invention to provide a hip belt having a split portion, whereby ventilation around the hip belt is enhanced.




The present invention is directed to an improved hip belt for backpacks and the like, the hip belt being adapted for transferring a portion of a carried to the user's hips. The hip belt attaches to the backpack and includes a belt portion that may be padded, and that wraps around the user's waist. The belt portion is split along at least a portion of the left and right sides. A front strap portion adjustably attaches the hip belt about the user's waist, preferably in a manner such that the desired tension is maintained in both the upper portion and the lower portion of the split belt. At least one semi-rigid transverse member interconnects the upper and lower portions of the split belt at an intermediate location.




In an embodiment of the present invention, the split hip belt comprises upper and lower portions that are approximately maintained at a desired separation.




In an embodiment of the present invention, the split hip belt flexibly conforms to the user, and thereby distributes the carried load over a comfortable area.




In an embodiment of the present invention, a split hip belt is adapted to maintain tension in both the upper leg and the lower leg of the hip belt during use.




In an embodiment of the invention, transverse members interconnecting the upper and lower portions of the split belt are elongate strips of a flexible material having an elongate stiffening groove.




In an embodiment of the invention, the transverse members connect to an upper edge of the upper portion of the belt and to a lower edge of the lower portion of the belt.




In an embodiment of the invention, a plurality of transverse members are provided on both the left and the right side of the hip belt.




In an embodiment of the invention, a pair of hip belt stabilizer straps are provided between the hip belt and the backpack and the hip belt, each stabilizer strap being located to pass over at least one of the transverse members.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to

FIG. 1

, a hip belt


100


according to the present invention is shown in use on a user


95


with a conventional backpack


90


. The hip belt


100


may be connected to the backpack


90


in any conventional manner as is well known in the art, for example, by fixedly attaching the hip belt


100


to a lower portion of the backpack


90


, or removably attaching the hip belt


100


using straps, hook-and-loop type fasteners, snaps, buttons, or any other suitable attachment device or combinations thereof. A suitable attachment device will provide for a portion of the weight of the backpack


90


to be transferred to the user


95


through the hip belt


100


during use, while also preventing excessive motion between the backpack


90


and the user


95


.




In the disclosed embodiment, a pair of stabilizer straps


110


(one shown) extend from the hip belt


100


to an attachment member


97


that is attached to a lower portion of the backpack


90


. The stabilizer strap


110


can be adjustably tightened to permit the backpack


90


to be comfortably snugged up against the hip belt


100


and the user


95


. The hip belt


100


includes a back portion


120


, a split right portion


130


, a split left portion


150


(see FIG.


2


), and a front strap portion


170


. It will be appreciated from

FIGS. 1 and 2

that the back, right, left, and front portions


120


,


130


,


150


, and


170


cooperatively define a generally hoop-shaped hip belt


100


that is adapted to be adjustably affixed about the user's hips. In the disclosed embodiment, a hook-and-loop type fastener panel


122


is affixed to the interior surface of the back portion


120


for attachment to the backpack


90


, for example, to the lumbar support (not shown).




The split left and right portions


130


,


150


each include an upper leg


131


,


151


and a lower leg


132


,


152


, each leg connected at one end to the back portion


120


and at the other end to the front strap portion


170


. In the disclosed embodiment, the split left and right portions


130


,


150


and the back portion


120


are formed as an integral assembly. The right portion upper and lower legs


131


,


132


are connected at or near their distal ends with a strap attachment panel


171


. The strap attachment panel


171


is a generally flat and flexible, generally pi-shaped panel having an upper rearward leg


171


A that attaches to the right portion upper leg


131


, and a lower rearward leg


171


B that attaches to the right portion lower leg


132


. As seen most clearly in

FIG. 3

, the forward legs


171


C,


171


D of the attachment panel


171


adjustably attach to a first strap


180


, wherein the first strap


180


has one end fixedly attached to the lower forward leg


171


D of the attachment panel


171


and an opposite portion that adjustably attaches to the upper forward leg


171


C of the attachment panel


171


. A first buckle member


182


slidably engages the first strap


180


at an intermediate location.




A second strap attachment panel


173


attaches in a similar manner to the left side upper and lower legs


151


,


152


. In the disclosed embodiment the strap attachment panels


171


,


173


are generally identical. The upper and lower rearward legs


173


A,


173


B of the second attachment panel


173


attach to the upper and lower legs


151


,


152


of the hip belt left portion


150


and a second strap


184


attaches to the forward legs


173


C,


173


D. A second buckle member


186


that is adapted to releasably engage the first buckle member


182


is slidably disposed at an intermediate location on the second strap


184


. Each of the straps


180


,


184


is provided with a conventional strap keeper


187


that permits the user to adjust the effective length of the respective strap to provide the desired tension in the hip belt straps.




It will be appreciated that the hip belt


100


can be adjustably fastened about the user's waist. Moreover, the attachment panels


171


,


173


that connect the adjustable straps


180


,


184


to the left and right portions of the hip belt


130


,


150


are connected such that a first end of each strap


180


,


184


is connected to the corresponding lower leg


132


,


152


of the hip belt left and right portions and the other end is connected to the corresponding upper leg


131


,


151


, whereby the tension in the straps


180


,


184


will be distributed approximately evenly to both the upper and lower portions of the hip belt


100


. In the preferred embodiment the buckle members


182


,


186


are freely slidable on the associated straps


180


,


184


. When the adjustable straps


180


,


184


are tightened, both the upper legs


131


,


151


and the lower legs


132


,


152


of the hip belt


100


will engage the user's hip, and therefore, the load carried by the hip belt


100


will be distributing between both the upper and lower legs of the hip belt


100


, increasing the user's comfort by spreading out the load over a larger area. The present invention provides the advantage of spreading the load over a larger area while also allowing improved ventilation by splitting the belt longitudinally.




The circumference at the lower edge of the hip belt


100


is larger than the circumference at the upper edge of the hip belt


100


, such that the hip belt


100


tapers to fit comfortable about the upper portion of the user's hip, with the narrower upper edge about the user's waist, whereby the vertical load carried by the hip belt


100


rests on the user's hips, and the hip belt


100


will not slide downwardly during use.




A semi-rigid transverse member


200


interconnects each pair of upper and lower legs at an intermediate location, a first transverse member


200


connecting upper leg


131


with lower leg


132


and a second transverse member


200


connecting upper leg


151


with lower leg


152


. In the disclosed embodiment, the transverse members


200


are elongate strips of a suitable flexible material. Examples of suitable materials include semi-rigid strips of polypropylene, nylon, or polyester, although any suitably semi-rigid material may be utilized and is contemplated by the present invention.




As seen most clearly in FIG.


2


and

FIG. 3

, in the disclosed embodiment of the hip belt


100


the transverse members


200


are provided with an outward curvature, such that the center part of the transverse member is disposed a distance away from the hip belt left and right portions


130


,


150


. This configuration permits the spacing between the legs on each side of the hip belt


100


to vary, the spacing accommodated by flexure of the transverse members


200


. For example, the right portion upper and lower legs


131


,


132


can move slightly further apart by the application of a force that tends to straighten out the curvature in the transverse member


200


. Similarly, the right portion upper and lower legs


131


,


132


can move closer together by flexing the transverse member


200


to greater curvature.




It will be readily apparent to one of skill in the art that the stiffness/flexibility of the transverse member


200


can be readily selected to a desired value by varying the width, thickness, and/or geometry of the transverse member


200


. In the disclosed embodiment, for example, a longitudinal groove


210


in the transverse member


200


, and thickened edge portions


220


increase the flexural stiffness of the transverse members


200


without significantly increasing the weight. It will also be appreciated that although elongate transverse members


200


are disclosed in the preferred embodiment, other shapes for the transverse members


200


are also contemplated by this invention. For example, X-shaped, oval-shaped, or more complicated-shaped transverse members could also be utilized.




Referring again to

FIG. 1

, in the preferred embodiment each stabilizer strap


110


is positioned such that when the stabilizer strap


110


is attached to the backpack


90


, it passes over the transverse member


200


at or near midspan. The stabilizer strap


110


is taut between the attachment member


97


and the hip belt


100


. Therefore, the stabilizer strap


110


will provide an inward force on the curved transverse member


200


, effectively further increasing the stiffness of the transverse member


200


.




In the preferred embodiment, a twill tape


250


is sewn around the periphery of the hip belt back, left and right portions


120


,


130


and


150


, the stitching also attaching the longitudinal members


200


and the attachment panels


171


,


173


to the hip belt left and right portions


130


,


150


. As shown in

FIG. 4

, a cord


164


may also be provided at the edges. In particular, the transverse members


200


and the attachment panels


171


,


173


are attached to the hip belt left and right portions


130


,


150


at or near the upper edge of the upper legs


131


,


151


and the lower edge of the lower legs


132


,


152


. By attaching the transverse members


200


and panels


171


,


173


near the outer edges, the left and right portion legs


131


,


132


,


151


,


152


of the hip belt are able to rotate generally about their longitudinal axis and thereby conform more closely to the hip shape of the user, and to more evenly spread out the carried load.





FIG. 4

shows a cross sectional view of the belt


100


taken along break line

4


of FIG.


2


. In this embodiment the upper and lower legs


131


,


151


include a core portion


260


, such as a perforated closed-cell foam. Other materials may also be utilized, including both organic materials such as cotton, and inorganic materials such as suitable polymer materials. The core portion


160


is relatively thick and compliant, providing padding to the user and facilitating a snug fit about the user's hips. A relatively stiffer foam stiffener panel


261


is provided and preferably comprises a flexible and porous material such as a perforated closed-cell foam panel. The core


260


and stiffener panel


261


are generally surrounded by an outer panel


262


that is preferably a breathable fabric that is rugged enough to withstand the bumps and abrasions likely to occur during use. The twill tape


250


is stitched


263


around the edges to close the outer panel


262


and attach the transverse member


200


to the hip belt


100


. In the preferred embodiment the core portion


260


, stiffener panel


261


, and outer panel


262


are breathable materials, for example, with perforations or a woven material, as indicated schematically in

FIG. 4

by the horizontal channels


265


, in order to enhance ventilation and improve the user's comfort.




A second embodiment of a hip belt


300


according to the present invention is shown in FIG.


5


. The hip belt


300


is similar to the first disclosed embodiment described above, including a back portion


120


, a right portion


130


, a left portion


150


and a front strap portion


170


. The right portion


130


is split longitudinally along a portion of its length, defining an upper leg


131


and a lower leg


132


, and the left portion


150


is similarly split longitudinally along a portion of its length, defining an upper leg


151


and a lower leg


152


. The back, right, and left portions


120


,


130


,


150


preferably form an integral padded portion of the hip belt


300


, wherein the hip belt


300


can be releasably closed and adjustably tightened with the front strap portion


170


comprising a first strap


180


, a second strap


184


, each strap having an associated buckle member


182


,


186


.




In this second embodiment, the hip strap


300


includes additional transverse members


200


spaced longitudinally over the split portion of the hip belt left and right portions


130


,


150


. Although two transverse members


200


are shown in

FIG. 5

on each side of the hip belt


300


, it will be readily apparent that more than two transverse members


200


could alternatively be used. The additional transverse members provide added stiffness and transverse strength between the upper and lower legs


131


,


132


and


151


,


152


. It is also contemplated that by utilizing a additional transverse members


200


the length of the portion of the hip belt


300


that is split can be increased, including for example, a constructions wherein split extends for the entire longitudinal length of the back, right, and left portions, such that the upper leg of the hip belt is separate from the lower leg of the hip belt.




While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
