BCTAILED^ESCRiraQN
[0013] Referring now to Figs. 1, 3 and 4 of the drawing, a backpack 10 is shown having a forward panel 11 that faces a user's back when worn and adjustable straps 12,13 extending from the top of the backpack 10 to the sides near the bottom of the pack for carrying the pack over the user's shoulders. A solid sheet 14, as of plastic or a composite, is sewn into the backpack 10, across and upward. Optionally, an adjustable waist belt (not shown) for securement about the user's waist may be provided. Normally, the forward panel 11 forms one wall of a rearward-facing pack for carrying various articles. Typically, the backpack will have a number of other pockets for receipt and carrying of items as well.
[0014] In a typical embodiment the backpack is 20 inches high, 14 inches deep and 12 inches wide. However, the backpack is to be made with differing dimensions, depending upon the size of the user and application. The backpack is made of canvas, typically, except for the solid sheet 14.
[0015] The backpack is also provided with a strap 16 at its top for hanging the backpack when not being carried by a user.
[0016] The backpack 11 is provided with a cushioning, inflatable bladder 21, including a lower part 22 which extends across the bottom beneath the pack, and an upwardly extending part 23 positioned entirely across the forward panel and from near the bottom, typically four inches from the bottom, extending upwardly, typically 8 to 10 inches, so as when inflated, it generally conforms to the shape of the curvature of the thoracic region of the spine (Fig. 4). The bladder 21 is of flexible material such as rubber, elastomeric or polymeric material.
[0017] The bladder 21 is enclosed within a zippered bag wrapped around it that is joined to the outer surface of the backpack 10.
[0018] There may also be included a strap 24 for tightening the backpack 10 against the user's body.
[0019] In accordance with a first aspect of the invention and referring to Fig. 3, the straps 12, 13 are provided with inflatable bladders 31, 32, located interiorly of the straps 12, 13. These bladders 31, 32 are so positioned that when inflated extend over the shoulders and partway down the front of the user.
[0020] Tubing 33 (Figs. 3 and 5) extending from the bladders 21, 31 and 32 leads to an open-and-close valve 34 with a mouthpiece 35. The tubing 33 is all interior of the backpack, making it less susceptible to damage. When not in use, the valve 34 and mouthpiece 35 are stored within a rear mesh pocket 36. Valve 34 controls the amount of airflow into the bladders 21, 31 and 32 by the user blowing into the mouthpiece 35, maintains the bladders in inflated position after air has been blown in, and also permits deflation of the bladders. Optionally, a hand operated pump and valve arrangement may be used such as that shown in my co-pending application Serial No. 11/101,044. The inflation by blowing, however, shortens the time needed for inflation.
[0021] In accordance with another aspect of the invention and as shown in Fig.4, padding 41, as of foam, is positioned along the front panel 11 of the backpack 10 extending from the uppermost part of the backpack 10 down to where it would meet the upper part 23 of the bladder 21, when in inflated position. Padding 41 is thinner at the top, say two inches thick, and wider at the bottom, say four inches, and extends completely across the front panel 11. The padding 41 may also be curved at its bottom and overlap slightly the upper part 23 of bladder 21.
[0022] In use, the user straps the backpack 10 on his shoulders so it rests comfortably on same. After or along with inflation, the shoulder straps 12, 13 may be adjusted so that the backpack finds itself in the desired position.
[0023] The user then removes the valve 34 with its mouthpiece 35 from its pocket 36. The valve 34 and mouthpiece 35 are easily accessible. The bladders 21, 31 and 32 are then inflated, the amount of inflation being dependent upon the individual's comfort level. In partially inflated position, the bladders begin to expand as they are filled with air by the user blowing into the mouthpiece 35. The proximity of the mouthpiece and valve to the user's mouth makes it easier and more convenient to use. When fully expanded to the satisfaction of the user, as shown in Fig. 4, the lower part 22 of the bladder 21 will rest against the lumbar region of the user and upon the user's buttocks, while the upper part 23 of the bladder 21 generally conforms to the curvature of the thoracic region of the user's body and rests comfortably against the back of the user.
[0024] The solid sheet 14 at the bottom and front of the backpack 10 prevents the expansion of the bladder from taking up space in the pack. In this way it is assured that the lower part 22 and upper part 23 of the bladder 21 will expand under and upwardly along the backpack 10 and not into the area where items are held.
[0025] In inflated condition, the backpack 10 comes off at an angle with the user's back. The padding 41 fills in the void created at the small of the back. The padding 41 goes down to and rests upon the upper part 23 of bladder 21 in its expanded position. As explained, it is thinner at the top and thicker at the bottom. It also widens from top to bottom as shown in Fig. 3. Thus, the padding 41 increases in both thickness and width as it goes down the backpack. The padding 41 makes the backpack more comfortable to wear and keeps the user from tightening the back too tight against the back.
[0026] With the backpack inflated, the user may then tighten it against the back by use of the strap 24. [0027] With the current design, weight-load in the backpack 10 is shifted to the top of the buttocks area. This, in turn causes a certain amount of stress on the chest in front of the shoulder. Thus, the inflatable bladders 31, 32 within the straps 12, 13 extend from the top of the shoulders and down the front partway against the chest to relieve any stress on the chest in front of the shoulders.
[0028] 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 pack 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.
[0029] The backpack can be made in different styles and sizes, for example, a student pack, one for hiking and one for military use.
[0030] It should be obvious that changes, additions and omissions may be made in the details and arrangement of parts without departing from the spirit and scope of the invention as hereinafter claimed.
