Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to bags, carrying cases, and luggage, and more particularly to a bag that is especially useful as a flight bag.  
       BACKGROUND OF THE INVENTION  
       [0002]     Carrying cases for holding various papers, files, maps, clothes, computers, sports equipment, and other objects are often sized to accommodate a large number of different items. Such cases or bags are often used by travelers, commuters, businesspeople, students, and others to conveniently transport various items from one place to another. Many carrying bags have been customized over the years to hold certain sized objects and papers, such as the common expandable briefcase, which is sized to accommodate a number of files.  
         [0003]     However, some members of the population continue to find it difficult to use currently available bags for certain applications. For example, aircraft pilots typically carry with them items including maps, writing instruments, flashlights, batteries, hand-held electronics (such as radios), and other items in bags that are generally not customized to their particular needs. While there have been a number of bags manufactured with pockets to hold some standard size papers, files, and pencils, the maps used by aircraft pilots are generally just filed into an oversized pocket within the bag.  
         [0004]     Aircraft pilots generally need to have their maps, particularly their Sectional Aeronautical Charts maps from by the U.S. Department of Transportation&#39;s Federal Aviation Administration (FAA), readily available during flight. Pilots may also need Terminal Area Charts and/or World Aeronautical Charts readily available. Often pilots will traverse large geographic regions that encompass multiple aeronautical sections in a single flight, requiring access to multiple maps. As a result, pilots may need to access certain of their maps several times during a flight. However, it is difficult to rifle through the typical carrying bags to find the desired map while also providing adequate attention to the task of piloting the aircraft. Furthermore, during some flights where the pilot is required to rely solely on his instruments to guide the aircraft, it may be even more important for the pilot quickly find and access the correct maps with a minimum of attention diverted from the airplane&#39;s instruments. If the pilot has trouble locating his maps and diverts attention from his instruments and his flying duties for an extended period while fumbling around for his maps, a sudden change in direction or other sudden movement, a drop in elevation, or just a lack of concentration can quickly disorient a pilot. Current carrying bags do not provide a quick and convenient way for pilots to organize and find their maps and other items. Therefore, there is a need for a flight bag capable of organizing maps and other items for quick and easy reference that minimizes the diversion of a pilot from his flying duties.  
       SUMMARY OF THE INVENTION  
       [0005]     The present invention provides a piece of luggage or carrying case for storing and transporting various items. The carrying case is especially useful as a flight bag. The carrying case includes an organizing flap hinged to the carrying case, and one or more organizing pockets or internal flaps that are hinged to the organizing flap. However, the organizing pockets are hinged a distance away from the hinge of the organizing flap. The organizing pockets can thus be opened and rotated like pages of a book for convenient storage and easy access to particular items or papers. The organizing pockets are sized according to some embodiments to hold Sectional Aeronautical Charts, Terminal Area Charts, and/or World Aeronautical Charts. The pockets may leave a title block of the maps exposed for the convenience of pilots or other users. The rotatable organizing pockets are easily accessible to pilots to allow a pilot to direct more of his or her attention to piloting an aircraft and less time fumbling through files or pockets to locate maps and papers. The rotatable organizing pockets enhance pre-flight planning and allow the pilot to organize maps according to the expected order of use.  
         [0006]     According to some embodiments, the organizing pockets of the carrying case are individually or collectively removable from the flight bag. Accordingly, the organizing pockets may be attached by releasable fasteners which may include rings, channels, hook and loop tape, or other components.  
         [0007]     Other objects, features, and advantages of the invention will become apparent from the following detailed description of the invention with reference to the accompanying drawings.

       DETAILED DESCRIPTION OF THE INVENTION  
       [0022]     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.  
         [0023]     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.” 
         [0024]     Turning now to the figures, and in particular to  FIGS. 1-3 , a piece of luggage or carrying case is shown according to principles of the present invention. According to  FIGS. 1-3 , 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  FIGS. 1-3  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.  
         [0025]     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.  
         [0026]     The flight bag  100  also includes an organizing flap  122 . According to  FIG. 1 , 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  FIGS. 2-3 . According to  FIGS. 2-3 , 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 .  
         [0027]     The organizing flap  122  includes an interior surface  128  ( FIGS. 2-3 ) to which one or more interior organizer pockets or flaps  130  ( FIGS. 2-3 ) are hinged. According to the embodiment of  FIGS. 2-3 , 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  ( FIG. 3 ) 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  FIGS. 2-3 . 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  ( FIG. 3 ) for holding items such as flashlights, pens, pencils, or other utensils.  
         [0028]     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.  
         [0029]     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.  
         [0030]     According to the embodiment of  FIGS. 2-4 , each of the interior organizer pockets  130 ,  132 ,  134  is sized to hold a Sectional Aeronautical Chart  170  ( FIG. 4 ). 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 .  
         [0031]     Currently, a folded Sectional Aeronautical Chart measures approximately 5 inches wide and 10⅜ inches long, with a thickness of approximately {fraction (1/8)} 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  FIG. 1  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.  
         [0032]     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  ( FIGS. 2-3 ) 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 .  
         [0033]     The flight bag  100  also includes a gap  154  ( FIGS. 2-3 ) inside the organizer flap  122  between the base  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  FIG. 12 .  
         [0034]      FIGS. 5-8  show the principle views of the flight bag  100 , with like elements numbered in the same manner as shown in  FIGS. 1-4 .  
         [0035]     The interior organizer pockets or flaps  130 ,  132 ,  134  are shown in  FIGS. 1-8  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  FIG. 9 , 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  FIG. 10 , 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  FIG. 10 , 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 .  
         [0036]     Yet another detachable example is embodied in  FIG. 11 , which illustrates one or more rings. According to  FIG. 11 , 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  FIGS. 9-11  are merely exemplary.  
         [0037]     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.
