  • a backpack 10 is shown having a forward panel 11 that faces the user's back when worn and an expandable pouch pocket 12 .
  • the backpack can be of canvas, polyester, nylon, plastic, fabric, and the like, although certain portions of the backpack are preferably fabric.
  • the backpack 10 further includes adjustable straps 13 extending from the top of the backpack to the sides near the bottom of the backpack for placement of the straps 13 over a user's shoulders and positioning the backpack 10 behind the user's back.
  • An adjustable waist belt (not shown) for securement about the user's waist may be provided.
  • the backpack will have a zippered carrying pack 14 comprised of a number of pockets so that articles can be placed within and removed from the carrying pack 14 .
  • the backpack may also be provided with a strap 15 at its top for hanging the backpack when not being carried by a user.
  • the pouch pocket 12 is provided with a zippered opening along its top at 16 .
  • an angled, flexible board 17 as of plastic (P.E. board) or composite and an inflatable bladder 18 that is slid under the board 17 and carrying pack 14 .
  • Board 17 is stitched to the forward panel just above zippered opening 16 .
  • the bladder 18 is placed in the pouch pocket 12 and slid against and under the board 17 . In inflated position, the lower portion 19 of bladder 18 extends across the bottom beneath the pack 14 , while an upwardly extending portion 20 becomes positioned across the forward panel 11 corresponding generally to its length and width, so as, when inflated, it generally conforms to the shape of the curvature of the thoracic region of the spine.
  • the bladder 18 expands outward and not inward towards the carrying pack 14 .
  • the board 17 also prevents the bladder 18 from getting punctured.
  • the pouch pocket 12 also expands.
  • the pocket 12 is pleated in the lower corners, as at 21 to allow for expansion.
  • the bladder 18 is of flexible material such as rubber, elastomeric or polymeric material. It is provided with an air valve at 31 . In military and hiking applications, the backpack's bladder 18 can be pulled out and used as a pillow at night.
  • air valve 31 is embedded in the bladder 18 surrounded by a molded, thickened ring 32 .
  • the bladder 18 is inflated via the air valve 31 using, for example, an ordinary ball inflator needle N.
  • Valve 31 normally prevents air from escaping from bladder 18 , but will allow air to enter and escape the bladder 18 , as via the needle N.
  • Valve 31 includes: the locking cap 33 ; pin valve 34 that opens when needle N is inserted and closes upon the needle's removal; female member 35 for receiving the pin valve 34 ; and, bellows member 36 , as of PVC, joined to thickened ring 32 and surrounding female member 35 and which is expandable for easy access and can be pulled up or pushed down. Locking cap 33 holds pin valve 34 within female member 35 .
  • the forward panel 11 up to the zippered opening 16 , forms the front wall of pouch pocket 12 .
  • a composite 41 Sewn to this front wall is a composite 41 that includes an inner layer 42 of an expandable, durable, mesh fabric ( FIG. 9 ), and an outer, similar fabric layer 43 ( FIGS. 7 and 9 ).
  • Layers 42 , 43 could be a webbing fabric, nylon, polyester and the like.
  • a compressed, apertured foam frame 44 Sandwiched between layers 42 and 43 is a compressed, apertured foam frame 44 ( FIG. 9 ) such as compressed P.E., with cut-outs 45 , star-like in shape, and an array of horizontally and vertically aligned, bubbles 46 , as of soft, molded, foam-like resilient material such as P.E. ( FIGS. 6 and 9 ) positioned and glued within the apertures in frame 44 .
  • These cushioning bubbles 46 can be oval-shaped, circular, square and the like.
  • the frame 44 is molded with apertures for the receipt and holding of the foam bubbles 46 and portions cut out at 45 to allow for expansion and then the entire composite 41 heat sealed together.
  • the bubbles 46 are held in place by the compressed PE foam frame 44 . After heat sealing, the composite 41 is then sewn to the front wall 11 .
  • the composite 41 expands outwardly when the bladder 18 is filled and does not take room away from the interior of the backpack 10 .
  • a grommet 51 Disposed centrally of the composite 41 is a grommet 51 leading through an opening to the bladder valve 31 .
  • the upper part of the forward panel 11 includes a pair of pads 61 , as of foam material 62 of the same type as bubbles 46 , and covered with mesh fabric material 63 , similar to mesh material 42 and 43 , except more durable and rigid.
  • Pads 61 push the backpack 10 at an angle and keep the user from compressing the top of the backpack 10 against the user's back. They force the weight of what's inside the pack 14 to be transferred to the bottom of the air system so as to sit on the top of the user's buttocks.
  • the pads 62 are a mixture of common foam with soft covering molded foam.
  • the bladder 18 is inflated through the grommet 51 to the bladder valve 31 , using a ball inflator needle N.
  • the thickened ring 32 fits right against and under the grommet 51 .
  • the ring 32 helps to hold the position of valve 31 in the center of grommet 51 , and, due to its thickness, eases the placement and withdrawal of the needle N in valve 31 .
  • the valve 31 can be pulled up and the needle N inserted and then the valve 31 pushed down so that it doesn't hit the user in the back.
  • the user straps the backpack 10 on, fitting it to its desired position using the straps 13 .
  • the lower portion 19 of the pocketed bladder 18 will rest upon the user's buttocks.
  • the upper portion 20 of the bladder 18 conforms generally to the curvature of the thoracic region of the user's body and rests comfortably against the back.
  • the bladder 18 when placed in the pouch pocket 12 is so positioned to a generally L-shaped configuration, with the lower portion 19 for resting upon and generally conforming to the buttocks area of the user, and the bladder upper portion 20 continuing from the bladder lower portion, extending at an angle part-way up, so as to rest upon the user's back and generally conforms to the curvature of the thoracic region of the user's body.
  • the combined effect of the upper pads 61 and the bubbled composite 41 is to create air channels between the user's back and the backpack 10 and thereby reduce the accumulation of moisture on the user's back and shirt.
  • known prior art backpacks do not have large thick padding at the top such as the pads 61 . What this does is when the user adjusts the straps 13 , thereby pulling the backpack towards his back, these pads 61 help to keep the major portion of backpack 10 off the user's shoulders and back. It shifts the weight off the upper back and puts the weight lower towards the pocket pouch 12 and resting against the user's buttocks.
  • the feeling to the user is that a significant portion of the weight of the backpack and contents is removed.
  • the back is relieved from stress, weight and pressure.
  • the inflation of the air bladder moves the backpack away from the back, shifting some of the weight to now be borne by the shoulders and with part of the weight now being supported by the buttocks area.
  • the backpack can be made in different styles and sizes, for example, a student backpack, one for hiking, one for military use and can be made to carry a computer.
  • the pouch 12 is zippered at 16 to allow for removal and replacement of bladder 18 .
