  • 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.
  • the backpack 10 may be 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 and parallel with the back of a wearer, and the sides 18 are positioned generally adjacent the sides of a wearer.
  • each shoulder strap 20 is connected to the front panel 16 on outward side of the releasable closure 24 (i.e. on an opposite side of the releasable closure 24 relative to the back panel 16).
  • Each shoulder strap 20 may be secured to the body 12 at a position on the outer half, or outer 50%, of the width/thickness of the backpack 10, or on the outer 25% of the width/thickness (wherein the width/thickness direction is perpendicular to the back panel 16, and may be represented, for example, by dimension X0 in Fig. 9).
  • This configuration for the shoulder straps 20 may differ from conventional backpacks where the shoulder straps are connected to the back panel 16.
  • the straps 20 may be configured such that they are the only shoulder straps 20 of the backpack 10, and the backpack 10 lacks any other shoulder straps configured to fit around the shoulders of a wearer.
  • the backpack 10 may lack any straps and/or shoulder straps directly coupled to the back panel 16, and lack any straps and/or shoulder straps coupled to the backpack 10 at any position in the inner half of the thickness of the body 12, particularly in the upper half thereof.
  • the shoulder straps 20 may be configured to bear the entirely of the weight of the backpack 10 when the backpack 10 is worn (except possibly for frictional forces between a wearer's back and the back panel 16) or being donned or doffed, and configured that the entire shoulder strap 20 load is applied to the front panel 50 or front portions of the backpack 10, and none of the shoulder strap 20 load is directly applied to the back panel 16 or back portions of the backpack 10.
  • each shoulder strap 20 is coupled to the upper portion of the body 12 at no more one attachment location.
  • the positioning of the upper portion of the strap 20 as disclosed herein helps to ensure that pulling/tension loads, during wearing of the backpack 10, are largely or entirely applied to the front surface/front panel 50 of the backpack 10.
  • This arrangement pulls the full weight of the backpack 10 up against the wearer's back, moving the weight closer to the wearer's center of gravity where it is more easily borne and less likely to cause imbalance.
  • this arrangement distributes the load more evenly across the wearer's back.
  • the shoulder strap arrangement disclosed herein enables the backpack's load to be automatically pressed or constrained more evenly against the entirety of the wearer's back.
  • Each strap 20 can be made of a relatively flexible/pliable material, and coupled to the body 12 at only a single location, such that the straps 20 are pivotally attached at the upper attachment locations 20A and can be freely pivoted about the side panels 18 and generally be positioned on the front side of the backpack 10, as can be seen in Figs. 4B, 7 and 8c.
  • the straps 20 do not cross over or prevent access to the releasable fasteners 24, or at least the upper-most portions of the releasable fastener 24 or those portions of the releasable fastener 24 on the top surface 19, thereby providing full and free access to the inner cavity 14.
  • the backpack 10 may lack any clips, brackets, support members etc.
  • a yoke 21 which is in turn coupled to the front panel 50/body 12.
  • Yoke 21 is optional, and if used may be considered an extension of the strap or straps 20 and/or part of the shoulder strap assembly 25. When the yoke 21 is used, the straps 20 can still be considered to be attached to the front panel 50.
  • the releasable closure 24 may have an S-shape in side view.
  • the releasable closure 24 as shown 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, or within about 50%, or about 25% of the width of the body 12 at that position).
  • the releasable closure 24 may have 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.
  • 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 may continue on the opposite side 18 in the same pattern, or in a symmetrical or mirror image pattern, to that shown in Fig. 1.
  • the releasable closure 24 has a generally "S"-shape (or “reverse S” shape) in end view on both sides 18 of the body 12.
  • one or both sides of the releasable closure 24 may have a different shape than that shown in Fig. 5, such as a linear shape and accordingly, may have ends positioned in different locations along the sides 18 of the backpack 10.
  • the serpentine shape of the releasable closure 24 allows for easy side access to the major storage compartment 14.
  • 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 a side access opening. In this manner, access is provided to the major storage compartment 14 by only partially releasing/opening the releasable closure 24.
  • 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 an opening. 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.
  • the releasable closure 24 can be completely opened, thereby allowing access to the major storage 14 compartment via the top of the body 12/backpack 10.
  • 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.
  • the releasable closure 24 in the embodiment of Fig. 5 has first portion 24a and second portion 24b that form an angle therebetween of about 80 degrees, or less than about 100 degrees.
  • various portions of the releasable closure 24, or tangents thereof, in the embodiment of Fig. 5 may form an angle of less than about 100 degrees to form a relatively well-defined side flap 32.
  • Each side flap 32 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.
  • the releasable closure 24 on the side panel 18 may form a substantially, but not entirely, closed loop to prevent the side flap 32 from being completely separated from the backpack 10. Although only a single side flap 32 is visible in Fig. 5, it should be understood that both side panels 18 may include a side flap 32 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 (for example, closure 38 in Fig. 6) may be provided in the front panel 50 or the yoke 21 of the backpack 10 as shown to provide top/front access to the major storage compartment 14.
  • each releasable closure 36, 37, 38 may provide access to the major storage compartment 14.
  • the releasable closures 36, 37, 38 may provide access to auxiliary storage compartments that are positioned adjacent to the major storage compartment 14 which may be smaller than the major storage compartment 14.
  • Figs. 8 A and 8B illustrate an alternate embodiment in which the backpack 10' includes a front panel 50, back panel 16, opposed side panels 18, and bottom panel 56.
  • Compression straps 68 having a variable length may be provided on one or both sides of the backpack 10' to help adjust the size of the backpack 10' depending upon the size/bulk of its contents.
