- This invention relates to a convertible storage bag and more specifically to a storage bag which may be converted from a compact bag such as a backpack to an expanded bag such as a duffle bag.
- Duffle bags are widely known as having durable fabric material and having a rectangular elongated shape. Duffle bags are advantageous because they can conveniently hold a large amount of clothing or other items. Duffle bags may be easily manufactured and since they preferably are constructed of fabric, they can be conformed to provide larger space for packing or storage. However, duffle bags tend to be cumbersome and their larger dimensions and elongated shape make them difficult to transport. Further because of their construction, even when not full, a duffle bag will tend to take up more space than is necessary and is cumbersome to transport.
- backpacks tend to be a convenient means for transporting smaller items.
- Backpacks are sufficiently compact to be stored and easily transported by strapping the backpack on the back of a person.
- backpacks do not have sufficient size to carry large amounts of clothing or other items which would be desirable in situations such as extended stays.
- duffle bag which may be transported easily in a transportable configuration.

Description
- This invention relates to a convertible storage bag and more specifically to a storage bag which may be converted from a compact bag such as a backpack to an expanded bag such as a duffle bag.
- Duffle bags are widely known as having durable fabric material and having a rectangular elongated shape. Duffle bags are advantageous because they can conveniently hold a large amount of clothing or other items. Duffle bags may be easily manufactured and since they preferably are constructed of fabric, they can be conformed to provide larger space for packing or storage. However, duffle bags tend to be cumbersome and their larger dimensions and elongated shape make them difficult to transport. Further because of their construction, even when not full, a duffle bag will tend to take up more space than is necessary and is cumbersome to transport.
- Conversely, backpacks tend to be a convenient means for transporting smaller items. Backpacks are sufficiently compact to be stored and easily transported by strapping the backpack on the back of a person. However, backpacks do not have sufficient size to carry large amounts of clothing or other items which would be desirable in situations such as extended stays.
- Thus, there exists a need for a duffle bag which may be transported easily in a transportable configuration. There also exists a need for a duffle bag which can be converted into a lower capacity carrying device. There is a further need for a type of bag configuration which can be converted between a first compact mode for easier transport and a second expanded mode for greater carrying and storage capacity.
- There further is a need for a convertible bag that is easily converted between compact and expanded configurations.
- The purpose and advantages of the invention will be set forth in or otherwise apparent from the description and drawings that follow, as well as will be learned by practice of the invention.
- The present invention is generally embodied in a convertible bag having a front end portion with at least one storage compartment, a back end portion that when joined to the front end portion forms at least a second storage compartment, the front end portion and back end portion adapted to be joined by a zipper around a perimeter of the back end portion and further comprising a pair of toothed tracks and a slidable element, an extendable portion connected to and between the front end portion and back end portion and contained in the second storage compartment when the front end portion is joined to the back end portion to form a compact configuration, wherein when the front end portion and back end portion are no longer joined and are spaced apart, the extendable portion is adapted to be extended to form an expanded configuration, and wherein the zipper is adapted to have the slidable element remain engaged with the pair of toothed tracks at all times.
- In another aspect of the invention, a convertible bag is adapted to be converted from a compact configuration to an expanded configuration, the convertible bag having a front end portion with at least one storage compartment, a back end portion directly connectable to the front end portion by a zipper having a pair of toothed tracks engaged around a perimeter of the respective front end portion and back end portion, an extendable portion connected to and between the front end portion and back end portion and concealed between the front end portion and back end portion when the front end portion is directly connected to the back end portion forming a compact configuration, wherein when the front end portion and back end portion are no longer directly connected to each other, the front end portion may be spaced apart from the back end portion and the extendable portion may be extended to permit the convertible bag to form an expanded configuration; and wherein the zipper is adapted to have the slidable element remain engaged with the pair of toothed tracks at all times.

FIGS. 1-5 of the drawings, there is shown aconvertible bag 10 which may be converted from a compact configuration in the form of for instance a backpack, to an expanded configuration in the form of a duffle bag. As shown inFIGS. 1-2 ,convertible bag 10 is in the compact configuration of a backpack.Convertible bag 10 is generally constructed of rugged woven fiber material such as canvas, but may be made of alternative materials, natural or man-made.Convertible bag 10 is shown with a preferably flatback end portion 12, although other shapes may be suitable.Front end portion 14 may be flat or of other shapes, such as to accommodate, for instance, a storage compartment. In the backpack configuration shown inFIGS. 1-2 , a wearer may carrybag 10 via a pair ofstraps 16 which are attached proximate the top and bottom of flatback end portion 12. Flatback end portion 12 is thus capable of being worn in contact with a wearer's back.Straps 16 includebuckles 18 which may be used to adjust the length ofstraps 16 for improved comfort and fit for different individuals, anddetachable clips 19 at their lower ends. -
Front end portion 14 ofbag 10 is shown as having afirst storage compartment 20 and anoptional storage compartment 22.First storage compartment 20 is formed essentially by aflap 24 which may be opened or closed via azipper 26.Storage compartment 22 is formed by a pair ofside panels 28 and abottom panel 30.Bottom panel 30 may be reinforced with heavier material to provide better support for stored items. Atop portion 32 joinsside panels 28, and it will be appreciated that the top portion and side panels, or even the top portion, side panels and bottom panel may be formed from a continuous piece of material or may be separate pieces connected together, such as by sewing, gluing or by other suitable means of attachment. Afront panel 34 has alower portion 36 which is joined toside panels 28. Afront flap 38 is formed abovelower portion 36 and is joined via azipper 40 which is provided around the border oftop portion 32 andside panels 28 and allows access to thesecond storage compartment 22 when unzipped. Thefirst storage compartment 20 is formed as a pouch withflap 24 on thelower portion 36. An optional handle, in the form of aloop 42, preferably of fabric or other suitable material, is attached totop portion 32 to provide an additional means to carrybag 10 in this configuration. It will be appreciated that the optional handle proximate the top ofconvertible bag 10 may alternatively incorporate rigid materials as well, as may be desired. - Back
end portion 12 has a pair ofside panels 44 which are joined by atop portion 46 and abottom portion 48.Top portion 46 andbottom portion 48 are provided with extra support and are thus preferably constructed in part with heavy duty protective material, such as plastic, metal, or other suitable material. In this particular embodiment,convertible bag 10 is outfitted with an optional telescopic handle. To achieve this optional configuration,top portion 46 is fitted with aslot 50 which receives aretractable handle 52. InFIG. 1 , handle 52 is shown in the extended position and has afirst telescoping member 54 which may be extended fromslot 50 and asecond telescoping member 56 which extends fromfirst telescoping member 54 and has ahand grip 58 connected to its opposite end. However, various forms of retractable handles may be used, as are known in the art. - As best seen in
FIG. 2 ,bottom portion 48 has a pair ofsocket members 60 which each receive arotatable wheel 62.Handle 52 may be used to conveniently pullbag 10 onwheels 62 for particularly heavy loads when on relatively flat surfaces when in the compact configuration. -
Bag 10 may be transformed into a duffle bag as shown inFIGS. 3-5 . Amain zipper 70 joinsrespective side panels 44 andtop portion 46 ofback end portion 12 toside panels 28 andtop portion 32 offront end portion 14.Main zipper 70 may be opened to separatefront end portion 14 andback end portion 12, thereby expandingbag 10.Front end portion 14 andback end portion 12 form asecond storage compartment 66 which holds the material of anextendable portion 72, which is used to expandbag 10 to create a duffle bag configuration. -
Main zipper 70 is wrapped around the perimeter offront end portion 14 andback end portion 12, and is continued on aflexible track 74 which is terminated at astop 76. The duffle bag configuration has a pair oflarge side panels 78.Stop 76 is attached to the middle of thelarge side panel 78. With this zipper configuration, when a user expandsbag 10, the interlocking zipper toothed track portions remain enmeshed atstop 76, even whenbag 10 is expanded. This eliminates the awkward and time consuming practice of having to draw together two completely separated zipper toothed track portions and fumble through the process of having to align and insert one track end into the zipper slide element to get the zipper started. Moreover, theflexible track 74 helps tend to drawfront end portion 14 andback end portion 12 together automatically as the movable zipper slide element progresses on the zipper toothed tracks toward a closed position. - The carrying compartment in the duffle bag configuration is formed by
side panels 78, abottom panel 80 and atop panel 82, which it will be appreciated may be formed from a continuous piece of material or may be separate pieces connected together.Top panel 82 has aflap 84 which is attached by azipper 86 which provides access to the carrying compartment. In this embodiment,zipper 86 is in a U-shape, creatingflap 84. It will be appreciated thatzipper 86 may be straight, to create simply a slit for an opening, or may be of alternative shapes to create other opening shapes.Side panels 78 have a pair ofstraps 88 withloops 90 formed abovetop panel 82.Loops 90 may be joined together via ahandle 92 which has flaps which can be joined by a fastener system, such as snaps or Velcro®, to bindrespective loops 90 together for convenient carrying ofbag 10. The flaps ofhandle 92 may be separated in order to allowloops 90 to be separated from each other for better access to the carrying compartment. Unzipping themain zipper 70 allowsside panels 78 to be expanded to their full length.Front end portion 14 andback end portion 12 thus form the ends of the duffle bag configuration as shown inFIGS. 4-5 . - When
bag 10 is in the duffle bag configuration, it can be carried byloops 90 individually, or byhandle 92. Alternatively, the duffle bag configuration can be carried by a carryingstrap 94. Carryingstrap 94 preferably has two ends 96, each of which has adetachable clip 98.Back end portion 12 preferably has a locking tab 100 (best seen inFIG. 2 ) which is connected totop portion 46. The locking tab 100 onback end portion 12 provides an attachment point for adetachable clip 98 of carryingstrap 94.Front end portion 14 may have acenter reinforcing strap 102 which has alocking tab 104.Detachable clip 98 may be attached to lockingtab 104 to allows for attachment of carryingstrap 94. As a further alternative, it will be appreciated thatconvertible bag 10 may be towed by optional loop handle 42 while rolling onwheels 62. -
Back portion 12 has an optionalfurther storage compartment 106 behindretractable handle 52.Further storage compartment 106 is a shallow compartment with openings formed by aflap 108 and is accessible via an upper horizontal zipper 111 and a lowerhorizontal zipper 112.Flap 108 is attached on its sides to backportion 12.Storage compartment 106 may be opened andshoulder straps 16 and their respective attaching hardware may be stored therein when not in use. - Turning now to

Much like the first embodiment,convertible bag 210 may be converted from a compact configuration, such as in the form of a backpack, to an expanded configuration in the form of a duffle bag. As shown inFIGS. 6-7 ,convertible bag 210 is in the compact configuration of a backpack.Convertible bag 210 may generally be constructed of similar materials to those used inconvertible bag 10.Convertible bag 210 preferably has a flatback end portion 212, although other shapes may be suitable.Front end portion 214 may be flat or of other shapes, such as to accommodate a storage compartment. In the backpack configuration shown inFIGS. 6-7 , a user may carrybag 210 via a pair ofstraps 216 which are attached proximate the top and bottom of flatback end portion 212. Thus,convertible bag 210 may be worn as a backpack or otherwise carried.Straps 216 preferably includebuckles 218 which may be used to adjust the length ofstraps 216 for improved comfort and fit, anddetachable clip 219 at their lower ends. -
Front end portion 214 ofbag 210 is shown as having afirst storage compartment 220 and an optionalcenter storage compartment 222.First storage compartment 220 is formed essentially by aflap 224 which may be opened or closed via azipper 226. Optionalcenter storage compartment 222 is formed by a pair ofside panels 228 and abottom panel 230.Bottom panel 230 may be reinforced to provide better support. Atop portion 232 joinsside panels 228, and it will be appreciated that the top portion and side panels, or even the top portion, side panels and bottom panel may be formed from a continuous piece of material or may be separate pieces connected together by suitable means, and that a handle may be provided proximate the top ofbag 210, if desired. Afront panel 234 has alower portion 236 which is joined toside panels 228. A front flap 238 is formed above lower portion 238 and is joined via azipper 240 which is provided around the border oftop portion 232 andside panels 228 and allows access to thesecond storage compartment 222 when unzipped. Thefirst storage compartment 220 is formed as a pouch withflap 224 on thelower portion 236. -
Bag 210 may be transformed into a duffle bag as shown inFIGS. 8-11 .Main zipper 270 joinsrespective side panels 228 andtop portion 232 offront end portion 214 toback end portion 212. Thus,main zipper 270 may be opened to separatefront end portion 214 andback end portion 212, thereby expandingbag 210.Front end portion 214 andback end portion 212 form a second storage compartment 266 (best seen inFIG. 8 ), which holds the material of anexpandable portion 272, which is used to expandbag 210 to create a duffle bag configuration. -
Main zipper 270 is wrapped around the perimeter offront end portion 214 andback end portion 212 and is continued on aflexible track 274 which is terminated at astop 276. The duffle bag configuration has a pair oflarge side panels 278. Stop 276 is attached to the middle of thelarge side panel 278. As with the first preferred embodiment, this integrated zipper configuration eliminates the need to work to get two completely separated zipper toothed tracks started with a zipper slide element. Also,main zipper 270 tends to drawfront end portion 214 andback end portion 212 together automatically as a user zipsconvertible bag 210 toward a closed compact configuration. - The carrying compartment in the duffle bag configuration of this second embodiment is formed by
side panels 278, abottom panel 280 and a top panel 282, which it will be appreciated may be formed from a continuous piece of material or may be separate pieces connected together by suitable means. Top panel 282 has aflap 284 which is attached by azipper 286 which provides access to the carrying compartment.Side panels 278 have a pair ofstraps 288 withloops 290 formed above top panel 282.Loops 290 may be joined together via ahandle 292 which has flaps which can be joined by a suitable fastener system to bindrespective loops 290 together for convenient carrying ofbag 210. The flaps ofhandle 292 may be separated in order to allowloops 290 to be separated from each other for better access to the carrying compartment. Unzipping themain zipper 270 allowsside panels 278 to be expanded to their full length.Front end portion 214 andback end portion 212 thus form the ends of the duffle bag configuration as shown inFIGS. 9-11 . - When
bag 210 is in the duffle bag configuration, it can be carried byloops 290 individually, or byhandle 292. Alternatively, the duffle bag configuration can be carried by a carryingstrap 294.
