text: luggage items such as carrying cases and flight bags are not uncommon . nevertheless , there are many inconveniences associated with the pieces of luggage currently available . the typical pockets and accessories are often difficult to use to organize items and papers in an easily retrievable manner . therefore , the present specification describes a carrying case with new convenient features . the specification describes internally hinged pockets or flaps that facilitate convenient storage and retrieval . the internally hinged pockets or flaps are configured in a manner similar to pages of a book according to some embodiments , so that a user can easily flip through “ pages ” of stored items to find the one needed . the internally hinged pockets may be particularly useful for flight bags , however , the principles described herein are not so limited . the principles described herein may be applied to any luggage item . as used throughout the specification and claims , the term “ plate ” is used broadly to mean any item , the thickness of which is small or shallow in comparison with the other dimensions of the item . a “ flap ” is a projecting or hanging piece , usually , but not always , attached to an item at only one side . as used herein , a “ flap ” may also be closed or integrated with the item it hangs from . a “ shell ” is an external protective case or cover . a “ shell ” may be hard and rigid or soft and pliable . the words “ including ” and “ having ,” as used in the specification , including the claims , shall have the same meaning as the word “ comprising .” turning now to the figures , and in particular to fig1 – 3 , a piece of luggage or carrying case is shown according to principles of the present invention . according to fig1 – 3 , the carrying case is a flight bag 100 . the flight bag 100 includes an outer shell 102 which may be soft or hard . however , the embodiment shown in fig1 – 3 illustrates a soft outer shell 102 . the outer shell 102 may be made of polyester , rayon , cotton , plastic , or other fabrics and materials . the outer shell 102 defines an inner space that may be used to store any number of items . the flight bag 100 includes one or more pockets , for example a central pocket 104 and first and second side pockets 106 , 108 . the first and second side pockets 106 , 108 may each be sized , for example , to enclose a headset . each of the first and second side pockets 106 , 108 includes a first strap 110 at least partially sewn to the outer shell 102 with a first fastener 112 attached toward a first end 113 thereof . a second strap 114 is also attached to the outer shell 102 adjacent to the first straps 110 at each of the first and second side pockets 106 , 108 . a second fastener 116 is attached to an end of the second strap 114 and shaped to snappingly mate and lock with the first fastener 112 . a second end 118 of each of the first straps 110 is attached an anchor 120 . the anchor 120 may include a hole receptive an end of a carrying strap or other device . the flight bag 100 also includes an organizing flap 122 . according to fig1 , the organizing flap 122 is closed by a zipper 124 , and an external surface of the organizing flap 122 may thus form a portion of the outer shell 102 . however , the organizing flap 122 is hinged to the flight bag 100 in order to facilitate opening the flap 122 as shown in fig2 – 3 . according to fig2 – 3 , the organizing flap 122 is hinged at a base 126 of the flight bag 100 . therefore , the organizing flap 122 may lay open and , depending on the surface the flight bag is set upon , be arranged substantially coplanar with the base 126 . the organizing flap 122 includes an interior surface 128 ( fig2 – 3 ) to which one or more interior organizer pockets or flaps 130 ( fig2 – 3 ) are hinged . according to the embodiment of fig2 – 3 , there are three interior organizer pockets or flaps 130 , 132 , 134 , but fewer or greater numbers of pockets may also be used . each of the interior organizer pockets 130 , 132 , 134 comprises a stiff center plate 136 ( fig3 ) that is made , for example , of plastic and may be covered with fabric . the stiff center plate 136 is shown as a generally flat , rectangular member . the stiff center plate 136 has first and second open pockets 138 , 140 on opposite sides thereof according to the embodiment of fig2 – 3 . however , according so some embodiments there may only be a first or a second pocket 138 , 140 . the first and second pockets 138 , 140 are made of fabric and are therefore generally flexible . one or more of the interior organizer pockets 130 , 132 , 134 may include additional pockets 142 ( fig3 ) for holding items such as flashlights , pens , pencils , or other utensils . the interior organizer pockets 130 , 132 , 134 are each rotatable about a hinge - attachment 135 to the interior surface 128 of the organizing flap 122 . further , the interior organizer pockets 130 , 132 , 134 are only connected to the flight bag 100 at the interior surface 128 . the hinge - attachment of the interior organizer pockets 130 , 132 , 134 is also spaced from a hinge 137 of the organizer flap 122 to the base 126 . therefore , the interior organizer pockets may freely and independently rotate and open just like pages of a book attached to a binder . accordingly , items contained by the first and second pockets 138 , 140 are easily and conveniently accessible to users such as aircraft pilots . the spacing of the hinge - attachment 135 of the interior organizer pockets 130 , 132 , 134 from the hinge 137 of the organizer flap 122 is approximately equal to or greater than a width of one of the interior organizer pockets 130 , 132 , 134 . although each of the interior organizer pockets 130 , 132 , 134 is shown with substantially equal dimensions , this is not necessarily so . one or more of the interior organizer pockets 130 , 132 , 134 may be larger or smaller than the others . therefore , the spacing of the hinge - attachment 135 of the interior organizer pockets 130 , 132 , 134 is generally at least equal to the width of the interior organizer pocket having the greatest width . spacing the hinge - attachment 135 of the interior organizer pockets 130 , 132 , 134 a distance of at least the width of the organizer pockets allows the organizer pockets 130 , 132 , 134 to fully open and rotate without hindrance from other portions of the flight bag 100 . nevertheless , a spacing of the hinge - attachment 135 from the hinge 137 of the organizer flap 122 that is less than the width of the organizer pockets 130 , 132 , 134 is also contemplated according to some embodiments . according to the embodiment of fig2 – 4 , each of the interior organizer pockets 130 , 132 , 134 is sized to hold a sectional aeronautical chart 170 ( fig4 ). sectional aeronautical charts are readily available from the federal aviation administration and are used regularly by aircraft pilots and others . however , the interior organizer pockets 130 , 132 , 134 may not extend a full length of the stiff central member 136 , such that a title block and other information on the sectional aeronautical chart 170 remains exposed and readable even when fully inserted into one of the interior organizer pockets 130 , 132 , 134 . currently , a folded sectional aeronautical chart measures approximately 5 inches wide and 10⅜ inches long , with a thickness of approximately ⅛ of an inch . therefore , according to some embodiments the stiff central members 136 may comprise rectangular dimensions ranging between approximately 5 and 7 inches in width , and ranging between approximately 9 and 11 inches in length . according to some embodiments , the dimensions of the stiff central members 136 are approximately 6 inches in width and 10 inches in length . it will be understood , of course , that other dimensions may also be used , particularly if the size of sectional aeronautical charts changes . it will also be understood that the dimensions of the organizer flap 122 are large enough to accommodate the full length of the sectional aeronautical charts in order to allow the organizer flap 122 to close as shown in fig1 even if the charts extend beyond the length dimension of the stiff central members 136 . further , the first and second open pockets 138 , 140 may include rectangular dimensions comprising a width ranging between approximately 5 and 6 inches and a length ranging between approximately 8 and 9 inches . according to some embodiments , the width of the first and second open pockets 138 , 140 is approximately 5 . 5 inches , and the length is approximately 8 . 25 inches . the depth or thickness of the pockets 138 , 140 may range between an approximately snug fit with the stiff central member 136 and 0 . 5 inches according to some embodiments . other dimensions may also be used according to particular needs . with the organizer flap 122 open , a number of other features of the flight bag 100 are also exposed . for example , the interior surface 128 may include any number of elastic loops 148 ( fig2 – 3 ) to hold batteries , such as “ aa ” and “ aaa ” size batteries or others . further , the organizer flap 122 may house a number of additional internal pockets , such as a third pocket 150 sized to hold a hand - held radio , a gps ( global position system ) unit , or other electronic device . additional loops 152 for holding lights , writing utensils , or other instruments may also be housed in the organizer flap 122 adjacent to the third pocket 150 . the flight bag 100 also includes a gap 154 ( fig2 – 3 ) inside the organizer flap 122 between the base of the interior surface 128 and the central pocket 104 . the gap 154 is sized to receive any pilot knee board such as are commonly used in the industry and widely available from a variety of sources . one example of a knee board 300 prior to insertion into the gap 154 is shown in fig1 . fig5 – 8 show the principle views of the flight bag 100 , with like elements numbered in the same manner as shown in fig1 – 4 . the interior organizer pockets or flaps 130 , 132 , 134 are shown in fig1 – 8 permanently fastened at the hinge - attachment to the interior surface 128 . however , according to some embodiments , one or all of the interior organizer pockets 130 , 132 , 134 are individually or collectively removably hinged to the interior surface 128 . for example , with reference to fig9 , one or more interior organizer pockets 230 , 232 , 234 are attached to a cylinder 262 , and an interior surface 228 comprises a c - shaped channel 264 receptive ( at an end 260 ) of the cylinder 262 . another example is embodied in fig1 , which illustrates a hook and loop tape attachment between the interior surface 228 and the one or more interior organizer pockets 230 , 232 , 234 . according to fig1 , a first hook and loop tape element 270 is disposed on the interior surface 228 , and each of the interior organizer pockets 230 , 232 , 234 comprises a mating hook and loop tape element 272 a , 272 b , 272 c , respectively . therefore , each of the interior organizer pockets 230 , 232 , 234 can be easily removed from the interior surface 228 . yet another detachable example is embodied in fig1 , which illustrates one or more rings . according to fig1 , there are three openable rings 284 connected to the interior surface 228 and looping through each of the interior organizer pockets 230 , 232 , 234 . a lever 282 may be provided to open the rings , and the rings 284 may be attached to the interior surface 228 via a binder 280 . other removable mechanisms may also be employed , as the embodiments of fig9 – 11 are merely exemplary . while this invention has been described with reference to certain specific embodiments and examples , it will be recognized by those skilled in the art that many variations are possible without departing from the scope and spirit of this invention . the invention , as described by the claims , is intended to cover all changes and modifications of the invention which do not depart from the scope of the invention .
