Definitions
- the present invention relates in general to article carriers, and in particular to an new and useful backpack and laptop sleeve having air cushion features for increased comfort and for protection of a laptop computer carried by the backpack or sleeve.
- Another area of improvement addressed by the present application is the presence of a check valve cover that covers the mouth inflatable check valve of the prior backpack and thus improves sanitation and cleanliness of the mouth inflated check valve and its surrounding areas.
- the use of flexible but non-elastic material for the bladder was also found to be less desirable so that bladder material that is both flexible and elastic is now used in the approved backpack.
- the bladder is provided in the front pocket between the front face of the plate and the second front wall and at least the entire inside surfaces of the bladder have a non-smooth texture thereon for preventing sticking together of facing walls of the bladder to facilitating an initial inflation of the bladder.
- a pair of tubular extensions or tubes extend from the bladder and respectively into each of the shoulder straps, one of the tubular extensions being for inflating and deflating the bladder.
- a mouth-inflatable, normally closed check valve is connected to the one tubular extension at a location that is spaced from the bladder and positioned so as to be accessible to a user for inflating the bladder by blowing into the check valve while the shoulder strap is on a shoulder of the user, the check valve having a mouth engageable perimeter.
- a valve cover is detachably connected over the entire mouth engageable perimeter of the check valve for covering the check valve and keeping it clear.
- a pair of semi-rigid liners are respectively in the shoulder straps near the bladder to form a pair or semi-rigid channels for the tubular extensions near the bladder to facilitate inflating and deflating of the bladder through the one tubular extension.
- a further object of the present invention is to provide, either as part of the backpack, or as a stand-alone item, a laptop sleeve including a pair of cushion panels connected in a rear pocket of the backpack or as a stand-alone sleeve, each cushion panel comprising a plurality of spaced apart, parallel, permanently sealed and partially filled air tubes made of flexible elastic material with webs between the air tubes in each cushion panel, the air tubes of one cushion panel each facing the webs of the other cushion panel for minimizing a volume occupied by the cushion panels when there is nothing in a space between the cushion panels, and for cushioning a laptop computer placed between the cushion panels.
- Another object of the invention includes providing the check valve to have a flapper that is normally closed to prevent air from escaping from the bladder and including a push button on the flapper that is manually depressed to move the flapper and allow air to escape from the bladder to adjust the amount of air in the bladder for improved comfort.

- Fig. 1 shows an improved backpack 10 of the present invention which overcomes some of the short comings of the prior backpack of the above-identified published patent application by, among other things, providing a texture or embossed pattern on at least the inner surfaces of the bladder to avoid sticking, the use of inflatable shoulder strap tubes in both shoulder straps 30, along with a mechanism to permit free air flow in those tubes so that the backpack is perceived as being symmetrical and in no way defective, the inclusion of permanently inflated, elastic material tubes shown at 40, 42 and 44 in Fig. 2, in a main pocket or chamber in the backpack that may be closed by a zipper 18, or as a stand alone laptop sleeve of Figs.
- the improved backpack 10 of the invention comprises a first front wall 20 of heavy duty fabric such a heavy nylon fabric, a second front wall 22 of the same or heavier fabric spaced forwardly of the first front wall 20 and defining a front pocket 24 with the first front wall 20, and a generally rigid, preferably plastic plate 26 having a front face and a back face, the plate being in the front pocket 24 with the back face of the plate being adjacent the first front wall 20.
- a pair of the shoulder straps 30 are operatively connected to the body of the backpack, namely to at least one of the front walls 20 and/or 22 as shown in Figs. 4 to 6, for holding the plate against a back of a user with the second front wall 22 being between the plate 26 and the back of the user.
- Load bearing means such as a main and additional backpack pockets formed by a rear wall 12 and an interior partition wall 14 also of the same fabric as one or the other front walls, and connected to at least one of the front walls, are provided for holding an object or load.
- a rear pocket between walls 12 and 14 is closed by a further zipper 16.
- the plate pocket 24 formed of walls 20 and 22 also has a top zipper 19 for access to the plate pocket. This allows access to the plate pocket for airport security measures that do not permit closed storage volumes that may contain contraband.
- a pressurizable, flexible and elastic bladder 28 covers generally all of the front face of the plate 26, the bladder being in the front pocket 24 between the front face of the plate and the second front wall 22. At least the entire inside surface 27 of the bladder has a non-smooth texture or embossed pattern 29 thereon for preventing sticking together of facing walls of the bladder 28 to facilitating an initial inflation of the bladder.
- the outside surfaces of the bladder 28 may have the same or a different pattern or not pattern and all patterns are made by providing the surfaces of the mold for forming the bladder with a negative image of the pattern. For example, as shown in Fig.
- the pattern may be an embossed pattern of concentric circles or any other pattern that has the effect of keeping broad smooth surfaces of the flexible plastic material from contacting each other and therefore unavoidably sticking together.
- plastic like PU (polyurethane) or PVC (polyvinyl chloride) that stretch when impacted thus absorbing energy and not transferring the energy.
- PU polyurethane
- PVC polyvinyl chloride
- cushion panels forming a laptop sleeve that are each made of a plurality of spaced apart, parallel, permanently sealed and partially filled air tubes, are also made of flexible elastic material such as PU or PVC so that they too can stretch when impacted and absorb and transfer energy to protect the laptop computer in the sleeve.
- a pair of tubular extensions or tubes 32, 33 shown in Fig. 10 extend from the bladder 28 and respectively extend into each of the shoulder straps 30.
- One of the tubular extensions 32 is for inflating and deflating the bladder as will be explained later, although if desired both can be used for this purpose if both are provided with an inflation valve.
- a mouth-inflatable, normally closed check valve 34 is connected at least to the one tubular extension 32 at a location that is spaced from the bladder 28 and positioned so as to be accessible, as shown in Fig. 6, to a user for inflating the bladder 28 by blowing into the check valve 34 while the shoulder strap 30 is on a shoulder of the user, the check valve having a mouth engageable perimeter.
- a valve cover 35 having a rim around its perimeter is detachably connected over the entire mouth engageable perimeter of the check valve 34 for covering the check valve 34 and keeping it clear. To keep the cover from being lost it is permanently held to the valve perimeter by a tab 35a.
- the check valve 34 has an inwardly pushable flapper that is normally closed around and against the inner surface of the valve perimeter and held in place be internal air pressure in the bladder 28 and tube 32 to prevent air from escaping from the bladder.
- the flapper includes a central raised push button 39 on the flapper that can be manually depressed by the user to move the flapper inwardly away from the valve perimeter and allow some or all of the air to escape from the bladder to adjust the firmness and comfort of the bladder against the user's back.
- Two liners are provide again for symmetry, or in case both tubes 32 and 33 are to be provided with a mouth-inflatable valve 34.
- the liner of both inflation tube 32 and extra tube 33 keep the tubes from collapsing under the load on the shoulder straps, that would otherwise make it impossible to use the tube 32 for inflating or deflating the bladder 28.
- the other tube 33 is also automatically inflated by air from the bladder 28 that is allowed to move through the open channel made by at liner 37 so both tubes and both shoulder straps are inflated to the same extent and are therefore symmetrical.
- the material of the bladder can be of flexible but non-elastic vinyl or other plastic, but is preferably an elastic plastic like PU (polyurethane) or PVC (polyvinyl chloride) that stretch when impacted thus absorbing energy and not transferring the energy.
- PU polyurethane
- PVC polyvinyl chloride
- At least one front wall, but preferable the second front wall 22 against the user's back is made of mesh of better ventilation.
- the second front wall 22 can also or alternatively be of a stretchable textile forming the front pocket for holding the bladder 28.
- the bladder can be subdivided into a plurality of interconnected compartments, including a relatively large lower lumbar support compartment 28a, and a plurality of relatively small upper compartments 28b, 28c and 28d.
- the backpack bladder can be formed with a forwardly open central recess as is evident in Figs. 2, 2A and 2B for avoiding direct pressure against the users spine.
- the front pocket 24 can alternatively be downwardly open and the backpack further can comprise a releasable fastener like a hook and loop tape at a lower edge of the front panel as shown in Fig. 8 for access to the plate.
- a releasable fastener like a hook and loop tape at a lower edge of the front panel as shown in Fig. 8 for access to the plate.
- the backpack may include a laptop computer sleeve in the rear pocket against wall 20, or a stand-alone laptop sleeve that will be disclosed later in connection with Figs. 20 to 23.
- the sleeve comprises a pair of cushion panels connected in the rear pocket and behind the first front wall 20, each cushion panel comprising a plurality of spaced apart, parallel, permanently sealed and partially filled air tubes 40 made of flexible elastic material with webs 48 between the air tubes 40 in each cushion panel.
- the air tubes 40 of one cushion panel each face the webs 48 of the other cushion panel for minimizing a volume occupied by the cushion panels when there is nothing in a space between the cushion panels as shown in Fig. 2A, and for cushioning a laptop computer 50 placed between the cushion panels as shown in Fig. 2B.
- the cushion panels are made of an elastic plastic like PU or PVC that stretch when impacted thus absorbing energy and not transferring the energy to the laptop.
- the sleeve may also have a top permanently sealed and partially filled air tube 46 made of flexible elastic material, with top web 48 connected between one of the cushion panels, in this case the top of the front panel, and the top air tube 46 for covering and cushioning the space between the cushion panels, and a pair of side 42 and a bottom 44 permanently sealed and partially filled air tubes made of the same flexible elastic material connected respectively at the sides and the bottom of the space between the cushion panels for further cushioning the space as shown in Figs. 2 and 3.
- top web 48 connected between one of the cushion panels, in this case the top of the front panel, and the top air tube 46 for covering and cushioning the space between the cushion panels
- a pair of side 42 and a bottom 44 permanently sealed and partially filled air tubes made of the same flexible elastic material connected respectively at the sides and the bottom of the space between the cushion panels for further cushioning the space as shown in Figs. 2 and 3.
- a stand-alone laptop computer sleeve of the invention comprises a fabric outer covering 52 with a front panel with top zippered pocket 54 and a rear panel with top zippered pocket 56.
- the front and rear cover panels are connected to each other by a gusset 60 extending across the bottom and sides of the pocket panels.
- a top gusset 62 with a longitudinal main zipper 58 closes the perimeter of the cover and provides an access opening for inserting and removing a laptop computer.
- a pair of cushion panels each comprise a plurality of spaced apart, parallel, permanently sealed and partially filled air tubes 40 made of flexible elastic material with webs 48 between the air tubes 40 in each cushion panel.
- the front and rear cushion panels are inserted through the top zippers into the respective front and rear cover panels 54 and 55 in the direction of the arrows in Fig. 20.
- the air tubes 40 of one cushion panel each face the webs 48 of the other cushion panel for minimizing a volume occupied by the cushion panels when there is nothing in a space between the cushion panels.
- Fig. 21 shows the cover in a disassemble state before zippered cover panels 54 and
- the sleeve also preferably includes a top permanently sealed and partially filled air tube 46 made of flexible elastic material with a top web 48 connected between one of the cushion panels or the cover panel on that side, and the top air tube 46, for covering and cushioning the space between the cushion panels and any laptop therein.
- a pair of side 42 and a bottom 44 permanently sealed and partially filled air tubes made of flexible elastic material are connected respectively at the sides and the bottom of the space between the cushion panels for further cushioning the space. This is done by providing the gusset 60 with fabric side tubes 60a and 60c and a fabric bottom tube 60b, which each have an access opening for receiving a respective tube 42 or 44 in the direction of arrows in Fig. 23.
- the gusset is sewn to the front and rear cover panels to complete the sleeve.
- the tubes 42 and 44 can alternatively but inserted into the gusset tubes 60a, 60b and 60c, after the fabric cover is assembled. It has been found that even with no way to refill the tubes 40, 42, 44 and 46, the plastic material is sufficiently impervious so that the tubes will retain their cushioning effect for a period of years.
- the partial filling is also essential, e.g. each tube is only filled to about 60 to 90 percent of its full volume with air. This provides sufficient cushioning as the air moves around in each cushion to absorb an impact, but without excessive bouncing or rebound of the sleeve after a first impact, which violent bouncing would be counterproductive to protecting the laptop.
- the backpack 10 could be used to carry any load in, on or around the bag, such as a musical instrument, pieces of equipment, or virtually anything typically carried on the back.
- the bladder 28 has the lower region 28a that is substantially thicker than its upper region 28b when fully inflated as shown in Fig. 14 to provide a good cushion at the kidney or lumbar level of a wearer of the pack 10.
- the bladder 28 has the somewhat recessed central area 28c and raised, vertically elongated side regions 28d.
- the straps 30 are provided internally with U-section semi-rigid liners 36 and 37 having foam edges 38 and stitched in place so that in these regions where the strap 30 is normally compressed by the weight of the pack 10 the tubes 32, 33 are held open at semi-rigid channels formed under liners 36, 37.
- Figs. 7 to 9 show another arrangement where a bladder 28' is provided in a lower corner with the valve 34' and does not have the tubular over-the-shoulder extension 32.
- a pocket 24' is formed by a front panel 22' that is open downward and that can be closed over the embossed bladder 28' by securing it via a velcro fastener 23 to the bottom of the pack 10.
- Such an arrangement also has an unillustrated rigid plate 26.
- Figs. 16 through 19 show yet another embossed bladder 28" with a lateral short extension 32" provided with a valve 34".
- the unillustrated front panel 22 is formed with an aperture through which the extension 32" can extend for operation of the valve 34".
- Use of the backpacks with the embossed bladders 28' and 28" is the same as that with the bladder 28, that is the bladder is blown up hard to start with and then deflated partially for comfortable use.
