Abstract:
A travel bag is disclosed that includes a pair of flaps. The flaps fold with respect to each other to lay flat or can be positioned to lie adjacent with respect to each other as would be used in a travel bag. Each flap also has at least one sub-flap that enables similar orientation with respect to its respective flap. This combination enables the bag to be positioned flat as it would be if hung open, folded in half as a travel/garment bag or folded to one-quarter size as a travel carryon item or even smaller with additional sub-flaps. The bag can also include a series of pockets, at least some of which are in the form of modules, each may contain several receptacles or individual pockets.

CROSS REFERENCE TO RELATED APPLICATION 
     This application claims priority from U.S. provisional application Ser. No. 60/123,991, filed Mar. 11, 1999, abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     The invention herein relates to luggage and more particularly to a travel bag especially adapted for airline travel. 
     It is generally known that airlines and other transportation carriers restrict the amount of luggage that passengers can carry on board with them. Passengers therefore often reluctantly check luggage into the baggage compartment. Due to the high volume of checked luggage, some is lost. Consequently, the traveling public is often greatly inconvenienced by the loss or delay in receiving their personal items. Stricter regulations concerning carryon baggage has also forced travelers to limit the amount of items that they bring with them. 
     Another problem encountered by travelers that is related to luggage is pre-travel packing, “living out of the luggage” while away and repacking for the return trip. This process also leaves room for error in the fast paced world of the packing and traveling. These errors usually result in forgetting to bring items, and inadvertently leaving items in hotel rooms and the like. 
     Basic needs of the traveler in this area have thus far avoided the marketplace. A need exists for travel bags that conform to air carriers guidelines for size while allowing maximal packing efficiency and ease of locating and repacking travel items. 
     SUMMARY OF THE INVENTION 
     Present Invention: 
     In one aspect, the invention features a luggage or travel bag that includes a first flap and a second flat joined together by a flap connector disposed therebetween. At least one first sub-flap and at least one second sub-flap is positioned as part of the first flap and the second flap respectively, and located opposite to the flap connector. The device also includes a plurality of pockets attached to the first flap and the second flap. This combination of the flaps allows for multiple foldable configurations of the travel bag with storage of items in the pockets. 
     The system may also include a first flap and a second flat joined together by a flap connector disposed therebetween with the first flap including a fastener. In addition, two closure flaps are secured to each of the two sides of the second flap, adjacent to the flap connector. The closure flaps extend laterally from the respective sides of the second flap and include a fastener secured to the distal end thereof. This allows the closure flaps, when, folded around the sides of the second flap, to be secured by the fasteners on the closure flaps. This creates an enveloping feature about the area between said first flap and said second flap to more completely secure items in the bag. 
     In another aspect, the invention includes a method of varying luggage dimension utilizing the afore mentioned system of flaps and sub-flaps. By positioning the first sub-flap and the second sub-flap to be substantially coplanar with the first flap and the second flap respectively and then repositioning the first sub-flap and the second sub-flap to be substantially parallel but not coplanar with the first flap and the second flap respectively, the overall dimension of the bag will be altered. This ability enables the user to reduce the overall dimension of the luggage bag as needed or desired. The aforementioned ability to provide modular receptacles that are releasably secured to at least one of said flaps, also aids in the ability of groups of articles to be removed and added to the luggage device with the addition or removal of a single receptacle.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The object of the disclosed invention is to provide an improved method of packing, and in the use of luggage for traveling. The invention is especially useful in regard to carryon luggage for commercial transportation. The size of a piece of carryon luggage is strictly enforced by air carriers regarding the overall size of the device. Items over a specified size must the checked to the baggage claim resulting in delays for the traveler and in some cases lost luggage. The invention also discloses a modular packing system that can aid the traveler in reduced packing time and also reducing the likelihood of lost or forgotten travel items. 
     Referring to the drawings, FIG. 1 shows a simplified version of a travel bag in a single-fold position. In its single-fold position, the length of the bag is one-half its full, unfolded length. The bag includes a first flap  10  and a second flap  12  joined together by a flap connector  14 . The first flap  10  includes a first sub-flap  16  and likewise the second flap  12  includes a second sub-flap  18 . A plurality of pockets are included in the bag including an outside pocket  20  accessible by a zipper  22 . The outside pocket can be positioned in any or all of the flaps, including the sub-flaps and can be secured by any type of fastener commonly used in the art. Other fasteners include snaps and hook and loop type fasteners. 
     The flaps can be constructed of any of a number of materials. In an embodiment, a semi-rigid material  24  is used under a fabric cover material  26 . The semi-rigid material gives the invention a basic form, aiding in the appearance and function in offering protection to items stored within the first  10  and second  12  flaps. In this embodiment, a fold line  27  is created to separate the first sub-flap  16  from the rest of the first flap  10 . The fold line  27  does not include the semi-rigid material  24  so that the sub-flap  16  can change its orientation with respect to the rest of the flap  10 . In another embodiment the semi-rigid material  24  is only used in the flap connector  14 , leaving the first flap and the second flap  12  pliable to conform to the needed conditions. 
     The specifics of the semi-rigid material is not intended to be limiting to the scope of the invention, but suggested materials include cardboard, plastic metal and wood. In a similar manner the flap connector  14  is also desirable to be constructed of a material set similar to the flaps. 
     The first  10  and second  12  flaps include pockets on the inside as positioned in this figure. It is intended that the majority of all products that would be stored in the bag would be placed in these pockets. A removable pocket  28  is shown as being secured to the inside of the second flap  12 . This pocket would likely also include a type of fastener to secure items therein, here being shown as a zipper  30 . As previously disclosed, any type of fastener or other functional equivalent could be used in place of that shown. Below the removable pocket  28  is a mesh pocket  32  shown on the inside of the second sub-flap  18 . This pocket opening may be restricted from opening, preferably by an elastic strap  34  situated at the opening of the pocket  32 . 
     With the bag in the single-fold position shown in FIG. 1, the length of the flaps can be made great enough to carry a suit or other articles of clothing, such as pants that are lengthy with only a single fold. This is desirable because multiple folds can cause wrinkles that are difficult to remove by the traveler, especially adding the inconveniences of being away from home. If necessary the length of the bag can be reduced in size by folding the sub-flaps under the flaps. In this double-fold configuration (see FIG.  3 ), the length of the bag is one-quarter its full, unfolded length. Since this additional fold is so easily accomplished, this can be done temporarily to satisfy baggage officials and then unfolded shortly thereafter. This minimal time in a folded position minimizes the wrinkling effect on any long garments stored therein. 
     To carry the bag in this form two handles are included. The hand handle  36  is preferably secured to the center of the flap connector  14 . This allows single hand carrying of the bag in its long or open form. Also included is a long strap or shoulder strap  38  that is releasably secured by clips  40  to the rings  42  at the outer edges of the flap connector  14 . This allows the user to carry the bag “hands free” by placing the strap  38  over the shoulder of the user. 
     The bag is further shown in FIG.  2 . Here the first flap  10  includes a pair of fasteners  44  attached thereto. These fasteners  44  secure the closure flaps  46 , attached to the second flap  12 , to the first flap  10  to close the sides of the bag, thereby further securing the articles carried therein. This is accomplished by moving the closure flaps  46  in the direction of the arrows  48  to releasably secure the mating fasteners  50  to the fasteners  44  on each side of the bag. This type of fastener shown here is a hook and loop type fastener, and is considered to be the preferred embodiment due to the flexibility in placement of the adjoining parts. 
     Another fastener type would be a mechanical snap, the male position on the closure flaps  46  and the female portion on the first flap  10 . The positioning can be reversed and in either case the snaps do provide a secure means of fastening that does not wear after repeated usage. The limitation being the necessity of critical location of one part with respect to the other part. This can be a problem in a luggage device since a dissimilar amount and overall size of items can be packed. A possible solution would be multiple snaps on one component, preferably the first flap  10 . This would allow the snap on the appropriate closure flap  46  to vary in its position on the first flap according to the fullness of the invention. 
     The double fold orientation of this version of the bag is shown in FIG.  3 . The first sub-flap  16  and the second sub-flap  18  are folded inward, underneath the upper portion of the first flap  10  and the second flap  12  respectively. The closure flaps  46  can then be rotated about the side of the bag, enveloping the articles located therein, as shown by the arrows  48 . The fasteners  44  and mating fasteners  50  secure the closure flaps into position. Though only a double fold is shown, any number of folds can be made with this bag. As such, multiple sub-flaps can be created as part of the first flap  10  and the second flap  12 . The folding process would follow as is shown here for each sub-flap in that they could fold or remain unfolded, as is deemed desirable by the user. 
     Another security feature that can be used is shown on all versions of the bag, but primarily used only when the bag is in this double fold position. This feature includes the use of one or more bottom straps  52  that are secured to the back side of the second flap  12 . The straps  52  are then secured to the first flap  10  by use of male buckle  54  and the female buckle  56 . Coupling these buckles then positions the straps  52  under the first  10  and second  12  flaps, closing the bottom of the bag and securing the first  16  and second  18  sub-flaps in a captured position between the upper portions of the first flap  10  and second flap  12 . The result is a reduced size travel bag that can be made to conform to the rigid restrictions for carryon luggage. In addition, the foldability to a reduction in size makes the device more desirable to the user in that one bag is dynamically able to conform to multiple sizes to efficiently perform a variety of functions. This means the consumer only has to buy one bag where otherwise more bags would need to be purchased. 
     Another method of securing the bottom of the bag is by means of a zipper with one of each side of the zipper attached to each of the first sub-flap  16  and the second sub-flap  18 . By zipping the structure together the bag is then closed on the bottom, further securing the items therein. In addition to a zipper, mechanical snaps, or any other fastening means commonly know in the art could also be used as a functional equivalent. Also, the means of securing the straps  52  and the number of straps  52  are not intended to be limiting to the scope of the invention. A variety of fastening methods such as hook and loop and other mechanical snap devices known in the art are acceptable for this function. 
     The bag is shown in FIG. 4 in a unfolded or hanging position. What is shown here is the entire inside of the bag as it would appear hanging open, with all compartments and pockets accessible to the user. The first flap  10 , the flap connector  14  and the second flap  12  are in a top to bottom orientation with the closure flaps  46  laid out for display purposes. To assist in positioning the bag in this way an anchor strap  58  is connected to the first sub-flap  16 . The anchor strap  58  is preferably comprised of a substantially longitudinal strap material that is releasably secured to the first sub-flap  16  such that at least one end of the strap  58  can be unfastened from the sub-flap  16 , secured about a towel rack or other anchoring structure and then refastened to the sub-flap  16 . This allows the bag to be displayed as shown, with fall access to the pockets contained therein. 
     A variety of storage pockets are disclosed in their use with the bag itself. The removable pocket  28 , as referenced earlier, is shown here in more detail. The removable pocket is shown to be preferably manufactured out of a clear material, so that items can be easily seen therein. This is not a necessity of the invention, in that opaque materials would also function in the primary purpose, which is to store items. Utilizing the concept of clear material, the details of the items in the pockets can be more easily identified. The removable pocket includes a method of fastening to the bag. This is shown here as four strips  60 , each comprising one side of a hook and loop fastener. The long mating strips  62  are attached to the bag at various locations on the inside of the second flap  12  and short vertical mating strips  64  on the inside of the first flap  10 . This orientation is not specific to the invention but is done to demonstrate the diverse nature of these modes of attachment. As is shown here, a variety of sizes of pockets can be randomly arranged as deemed desirable by the user. Here a pair of small pockets  66  with their strips  60  attached thereto can be used in conjunction with or in place of large pockets  68 . 
     The mesh pockets  32  are situated on the inside of the second sub-flap  18 . These are likely used for loose items. The items are secured therein by the elastic strap  34 , as previously noted. 
     Permanent pockets  70  are also provided in this version of the bag. An opening that includes a flap  72  that is secured by a mechanical snap  74  is shown here. This method of opening and securing the pockets are interchangeable with the use of a zipper  75  in the large pockets  68  and the small pockets  66 . Other forms such as hook and loop fasteners are also acceptable in this application. 
     The permanent pockets  70  are shown here to include a set of hoop straps  76 . These hoop straps  76  are comprised of a substantially longitudinal strap with each end secured to an adjacent position to the first flap  10 . The hoop strap  76  is preferably manufactured of an elastic material so that the resulting loop or hoop between the fastened ends, can receive items of varying sizes and shapes, securing them in the pocket  70 , flap  10  or other supporting structure. These hoop straps  76  can also be attached to the second flap  12  (not shown) or to the flap connector  14 . On the flap connector  14  a pair of hoop straps  76  are shown adjacently positioned in a vertical orientation to support an item. Here a typical item such as a curling iron  78  is shown. 
     The specific orientation and display of the elements of the disclosed invention are considered to be the preferred embodiments, but are not intended to be limiting to the scope of the invention. It is understood that an infinite combination of variations in the use and placement of these pockets and straps is inherently included in this disclosure.
