Description

BACKGROUND

Backpacks are widely used by students and other users to store books, school supplies, travel supplies, etc. However, due to various physical constraints, it may be difficult to access the inner cavity of the backpack. For example, when an existing backpack is stored in the relatively narrow dimensions of a school locker, it can be difficult to access to the top/front of the backpack. Moreover, when a existing backpack is stacked adjacent to other components (i.e. in a luggage compartment or the like) it can be difficult to access the inner cavity. Accordingly, the present invention is directed to a backpack with improved side access.

DETAILED DESCRIPTION

As shown in FIG. 1, in one embodiment the backpack 10 of the present invention includes a body 12 with an inner cavity, or major storage compartment 14, therein. The body 12 includes a back panel 16 configured to lie adjacent to the back of a wearer, a pair of opposed sides 18, and a pair of shoulder straps 20. Alternately, if desired, rather than using two shoulder straps 20, a single shoulder strap 20 may be utilized to provide a backpack 10 also known as a “sling.” Each shoulder strap 20 extends from the top of the body 12/back panel 16 to the bottom of the body 12/back panel 16 to form a loop which can receive the wearer's arms therethrough. The backpack 10 is configured such that when it is worn by a wearer, the shoulder straps 20 are positioned over the shoulder of a wearer, the back panel 16 is positioned generally flat against the back of a wearer, and the sides 18 are positioned generally adjacent the sides of a wearer.

Each shoulder strap 20 can include cushioning or padding material (such as foam) thereon, and be of an adjustable length, to allow the backpack 10 to be carried on the back of the wearer in a well known manner. A carrying handle 22 may be positioned on the top of the body 12/back panel 16 between the shoulder straps 20 to provide a means by which the backpack 10 can be carried by hand. The body 12, shoulder straps 20 and handle 22 can all be made of a wide variety of flexible, durable sheet-like material, such as polymers (i.e. polyester, nylon), fabric, combinations of these materials, etc., in woven or various other forms.

A releasable fastener/closure 24 may extend around the body 12 such that when the releasable closure 24 is opened, access is thereby provided to the major storage compartment 14. The releasable closure 24 can take any of a variety of forms, including a zipper, a slide fastener, hook-and-loop fastening material (i.e. VELCRO®), snaps, magnets or the like.

In the illustrated embodiment, the releasable closure 24 has an end location 26 near the bottom of the body 12 (i.e. in the lower half of the body 12) and adjacent to the back panel 16 (i.e. within about 0-3 inches). From the end location 26, the releasable closure 24 has a first portion 24a that extends generally upwardly and outwardly (i.e. upwardly away from the back panel 16) to the outward-most position 28. The outward-most position 28 of the releasable closure 24 may be located in the outer half of the body 12 (i.e. in the half of the body 12 furthest away from the back panel 16) and/or at least about 3 inches, or at least about 4 inches, away from the back panel 16.

From the position 28, the releasable closure 24 has a second portion 24b that extends generally upwardly and inwardly towards the back panel 16 to an intermediate position 30 generally adjacent to the back panel 16 and/or one of the shoulder straps 20. The releasable closure 24 has a third portion 24c that extends upwardly and over the top of the body 12 at a distance generally uniformly spaced from the back panel 16 to the opposite side 18 of the body 12. The releasable closure 24 then continues on the opposite side 18 in the same pattern, or in a symmetrical or mirror image pattern, to that shown in FIG. 1. In this manner, the releasable closure 24 has a generally “S”-shape (or “reversed S” shape) in end view on both sides 18 of the body 12.

The serpentine shape of the releasable closure 24 allows for easy side access to the major storage compartment 14. In particular, as shown in FIG. 2, when the releasable closure 24 is unfastened to the intermediate position 30, a generally triangular side flap 32 is defined in the body 12. The side flap 32 can be pulled away from the rest of the body 12 to provide the side access opening 34 shown therein. In this manner, access is provided to the major storage compartment 14 by only partially releasing/opening the releasable closure 24. Moreover, the “S”-shape of the releasable closure 24 provides the side flap 32 which can be pivoted/folded away from the body 12 to define a definite opening 34. This can be contrasted with a simple “slit” opening provided by a linear releasable closure which does not provide the side flap or associated access and visibility.

As shown in FIG. 3, when full access is desired to the major storage compartment 14, the releasable closure 24 can be completely opened, thereby allowing access to the major storage 14 compartment via of the top of the body 12/backpack 10. Thus, the releasable closure 24 provides the option of side access to the major storage compartment 14 on either side 18 of the body 12/backpack 10, and also provides the option of full/top-access to the major storage compartment 14.

As shown in FIG. 1, various additional releasable fasteners/closures 36, 38 may extend across the front face of the body 12/backpack 10. In one embodiment, each releasable closure 36, 38 may provide access to the major storage compartment 14. Alternately, each releasable closure 36, 38 may provide access to an auxiliary storage compartment that is positioned adjacent to the major storage compartment 14.

FIGS. 4 and 5 illustrate an alternate embodiment of the invention. In this case, the backpack 10′ includes a front panel 50, back panel 52, opposed side panels 54, and bottom panel 56. A releasable closure 58 is positioned on each side panel 54. Each releasable closure 58 extends around generally the entire perimeter of the associated side panel 54 in a generally closed loop to define a side flap 60. In particular, the releasable fastener 58 may have an inner end position 62, and have a first portion 58a extending generally upwardly to an upper-most position 64. The releasable closure 58 has a second portion 58b extending generally downwardly and outwardly from the upper-most position 64 to an outer end position 66 that is spaced outwardly from the inner end position 62.

When the releasable closure 58 is fully opened/released, as shown in FIG. 5, the side flap 60 is freed and generally pivotable/moveable away from the body 12 to provide a side access opening 70 for access to the major storage compartment 14. The side flap 60 defined by the releasable closure 58 may comprise a significant percentage (i.e. in one case, at least about 60 percent, and in another case, at least 80 percent) of the associated side panel 54 to provide ease of access when opened.

The releasable closure 58 on the side panel 54 may form a substantially, but not entirely, closed loop to prevent the side flap 60 from being completely separated from the backpack 10′. Although only a single side flap 60 is visible in FIGS. 4 and 5, it should be understood that both side panels 54 may include a side flap 54 so that side access to the major storage compartment 14 can be provided regardless of the orientation of the body 12/backpack 10′. If desired, a top access releasable closure (not shown) may be provided in the front panel 50 of the backpack 10′ (i.e. immediately forward of the handle 22) to provide top/front access to the major storage compartment 14.

The releasable closure 24 in the embodiment of FIGS. 1-3 has first 24a and second 24b portions that form an angle therebetween of about 80 degrees, or less than about 100 degrees. Similarly, various portions of the releasable 58, or tangents thereof, in the embodiment of FIGS. 4 and 5 may form an angle of less than about 100 degrees to form a relatively well-defined side flap 66. Each side flap 32/60 may be foldable or pivotable about a root or base that is defined by end points of the releasable closure 24/58, or by sufficient changes in direction of the releasable closure 24/58 (see base b in FIGS. 1 and 4). Each base b may be relatively small to provide ease of pivoting/folding. For example, each base b may have a length that is less than about ½ or about ¾ the height of the side 18/54 of the backpack 10/10′, or have a length that is no more than about four times as long as the height h of the side flap 32/60 (measured perpendicular to the base).

The attached sheets A-E further illustrate various details of certain embodiments of the invention. However, it should be understood that the various materials, dimensions, and features shown therein are illustrative examples, and the materials, dimensions, and feature can vary from those shown in sheets A-E without departing from the scope of the invention.

Having described the invention in detail and by reference to the various embodiments, it will be apparent that modifications and variations thereof are possible without departing from the scope of the invention.
