Description
FIELD OF INVENTION
[0001] 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.
BACKGROUND OF INVENTION
[0002] 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.
[0003] 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.
[0004] 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.
[0005] There further is a need for a convertible bag that is easily
converted between compact and expanded configurations.
SUMMARY OF THE INVENTION
[0006] 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.
[0007] 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.
[0008] 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.
[0009] It is to be understood that both the foregoing general
description and the following detailed description are not limiting
and are provided purposes of explanation only. The accompanying
drawings, which are incorporated in and constitute part of this
specification, are included to illustrate and provide a further

art in light of the present disclosure.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] While the present invention is capable of embodiment in
various forms, there is shown in the drawings and will hereinafter
be described presently preferred embodiments, with the
understanding that the present disclosure is to be considered as an
exemplification of the invention. It should be understood that the
present invention is not limited to the preferred embodiments
illustrated.
[0028] Referring now more particularly to FIGS. 1-5 of the
drawings, there is shown a convertible 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 in FIGS. 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 flat back 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 in FIGS.
1-2, a wearer may carry bag 10 via a pair of straps 16 which are
attached proximate the top and bottom of flat back end portion 12.
Flat back end portion 12 is thus capable of being worn in contact
with a wearer's back. Straps 16 include buckles 18 which may be
used to adjust the length of straps 16 for improved comfort and fit
for different individuals, and detachable clips 19 at their lower
ends.
[0029] Front end portion 14 of bag 10 is shown as having a first
storage compartment 20 and an optional storage compartment 22.
First storage compartment 20 is formed essentially by a flap 24
which may be opened or closed via a zipper 26. Storage compartment
22 is formed by a pair of side panels 28 and a bottom panel 30.
Bottom panel 30 may be reinforced with heavier material to provide
better support for stored items. A top portion 32 joins side 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. A front panel 34 has a lower portion
36 which is joined to side panels 28. A front flap 38 is formed
above lower portion 36 and is joined via a zipper 40 which is
provided around the border of top portion 32 and side panels 28 and
allows access to the second storage compartment 22 when unzipped.
The first storage compartment 20 is formed as a pouch with flap 24
on the lower portion 36. An optional handle, in the form of a loop
42, preferably of fabric or other suitable material, is attached to
top portion 32 to provide an additional means to carry bag 10 in
this configuration. It will be appreciated that the optional handle
proximate the top of convertible bag 10 may alternatively
incorporate rigid materials as well, as may be desired.
[0030] Back end portion 12 has a pair of side panels 44 which are
joined by a top portion 46 and a bottom portion 48. Top portion 46
and bottom 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 a slot 50 which receives a
retractable handle 52. In FIG. 1, handle 52 is shown in the
extended position and has a first telescoping member 54 which may
be extended from slot 50 and a second telescoping member 56 which
extends from first telescoping member 54 and has a hand grip 58
connected to its opposite end. However, various forms of
retractable handles may be used, as are known in the art.
[0031] As best seen in FIG. 2, bottom portion 48 has a pair of
socket members 60 which each receive a rotatable wheel 62. Handle
52 may be used to conveniently pull bag 10 on wheels 62 for
particularly heavy loads when on relatively flat surfaces when in
the compact configuration.
[0032] Bag 10 may be transformed into a duffle bag as shown in
FIGS. 3-5. A main zipper 70 joins respective side panels 44 and top
portion 46 of back end portion 12 to side panels 28 and top portion
32 of front end portion 14. Main zipper 70 may be opened to
separate front end portion 14 and back end portion 12, thereby
expanding bag 10. Front end portion 14 and back end portion 12 form
a second storage compartment 66 which holds the material of an
extendable portion 72, which is used to expand bag 10 to create a
duffle bag configuration.
[0033] Main zipper 70 is wrapped around the perimeter of front end
portion 14 and back end portion 12, and is continued on a flexible
track 74 which is terminated at a stop 76. The duffle bag
configuration has a pair of large side panels 78. Stop 76 is
attached to the middle of the large side panel 78. With this zipper
configuration, when a user expands bag 10, the interlocking zipper
toothed track portions remain enmeshed at stop 76, even when bag 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, the flexible track 74 helps tend to
draw front end portion 14 and back end portion 12 together
automatically as the movable zipper slide element progresses on the
zipper toothed tracks toward a closed position.
[0034] The carrying compartment in the duffle bag configuration is
formed by side panels 78, a bottom panel 80 and a top 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 a flap 84 which is attached by a zipper 86 which provides
access to the carrying compartment. In this embodiment, zipper 86
is in a U-shape, creating flap 84. It will be appreciated that
zipper 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 of straps 88 with loops 90 formed above
top panel 82. Loops 90 may be joined together via a handle 92 which
has flaps which can be joined by a fastener system, such as snaps
or Velcro.RTM., to bind respective loops 90 together for convenient
carrying of bag 10. The flaps of handle 92 may be separated in
order to allow loops 90 to be separated from each other for better
access to the carrying compartment. Unzipping the main zipper 70
allows side panels 78 to be expanded to their full length. Front
end portion 14 and back end portion 12 thus form the ends of the
duffle bag configuration as shown in FIGS. 4-5.
[0035] When bag 10 is in the duffle bag configuration, it can be
carried by loops 90 individually, or by handle 92. Alternatively,
the duffle bag configuration can be carried by a carrying strap 94.
Carrying strap 94 preferably has two ends 96, each of which has a
detachable clip 98. Back end portion 12 preferably has a locking
tab 100 (best seen in FIG. 2) which is connected to top portion 46.
The locking tab 100 on back end portion 12 provides an attachment
point for a detachable clip 98 of carrying strap 94. Front end
portion 14 may have a center reinforcing strap 102 which has a
locking tab 104. Detachable clip 98 may be attached to locking tab
104 to allows for attachment of carrying strap 94. As a further
alternative, it will be appreciated that convertible bag 10 may be
towed by optional loop handle 42 while rolling on wheels 62.
[0036] Back portion 12 has an optional further storage compartment
106 behind retractable handle 52. Further storage compartment 106
is a shallow compartment with openings formed by a flap 108 and is
accessible via an upper horizontal zipper 111 and a lower
horizontal zipper 112. Flap 108 is attached on its sides to back
portion 12. Storage compartment 106 may be opened and shoulder
straps 16 and their respective attaching hardware may be stored
therein when not in use.
[0037] Turning now to FIGS. 6-11, there is shown a second
embodiment of a convertible bag 210 in accordance with the
invention. 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 in FIGS. 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 in convertible bag
10. Convertible bag 210 preferably has a flat back 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 in FIGS. 6-7, a
user may carry bag 210 via a pair of straps 216 which are attached
proximate the top and bottom of flat back end portion 212. Thus,
convertible bag 210 may be worn as a backpack or otherwise carried.
Straps 216 preferably include buckles 218 which may be used to
adjust the length of straps 216 for improved comfort and fit, and
detachable clip 219 at their lower ends.
[0038] Front end portion 214 of bag 210 is shown as having a first
storage compartment 220 and an optional center storage compartment
222. First storage compartment 220 is formed essentially by a flap
224 which may be opened or closed via a zipper 226. Optional center
storage compartment 222 is formed by a pair of side panels 228 and
a bottom panel 230. Bottom panel 230 may be reinforced to provide
better support. A top portion 232 joins side 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 of bag 210, if desired. A front panel 234 has a
lower portion 236 which is joined to side panels 228. A front flap
238 is formed above lower portion 238 and is joined via a zipper
240 which is provided around the border of top portion 232 and side
panels 228 and allows access to the second storage compartment 222
when unzipped. The first storage compartment 220 is formed as a
pouch with flap 224 on the lower portion 236.
[0039] Bag 210 may be transformed into a duffle bag as shown in
FIGS. 8-11. Main zipper 270 joins respective side panels 228 and
top portion 232 of front end portion 214 to back end portion 212.
Thus, main zipper 270 may be opened to separate front end portion
214 and back end portion 212, thereby expanding bag 210. Front end
portion 214 and back end portion 212 form a second storage
compartment 266 (best seen in FIG. 8), which holds the material of
an expandable portion 272, which is used to expand bag 210 to
create a duffle bag configuration.
[0040] Main zipper 270 is wrapped around the perimeter of front end
portion 214 and back end portion 212 and is continued on a flexible
track 274 which is terminated at a stop 276. The duffle bag
configuration has a pair of large side panels 278. Stop 276 is
attached to the middle of the large 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 draw front end portion 214 and back end portion
212 together automatically as a user zips convertible bag 210
toward a closed compact configuration.
[0041] The carrying compartment in the duffle bag configuration of
this second embodiment is formed by side panels 278, a bottom 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 a flap 284
which is attached by a zipper 286 which provides access to the
carrying compartment. Side panels 278 have a pair of straps 288
with loops 290 formed above top panel 282. Loops 290 may be joined
together via a handle 292 which has flaps which can be joined by a
suitable fastener system to bind respective loops 290 together for
convenient carrying of bag 210. The flaps of handle 292 may be
separated in order to allow loops 290 to be separated from each
other for better access to the carrying compartment. Unzipping the
main zipper 270 allows side panels 278 to be expanded to their full
length. Front end portion 214 and back end portion 212 thus form
the ends of the duffle bag configuration as shown in FIGS.
9-11.
[0042] When bag 210 is in the duffle bag configuration, it can be
carried by loops 290 individually, or by handle 292. Alternatively,
the duffle bag configuration can be carried by a carrying strap
294. Carrying strap 294 preferably has two ends 296, each of which
has a detachable clip 298. Back end portion 212 preferably has a
locking tab 300 (best seen in FIG. 7) which is connected to back
end portion 212. The locking tab 300 on back end portion 212
provides an attachment point for a detachable clip 298 of carrying
strap 294. Front end portion 214 may have a center reinforcing
strap 302 which has a locking tab 304. Detachable clip 298 may be
attached to locking tab 304 to allows for attachment of carrying
strap 294.
[0043] In this embodiment, bag 210 does not require any internal
volume to be dedicated to housing a telescopic handle assembly as
in convertible bag 10. Also, back end portion 212 houses a further
storage compartment 306 formed by a flap 308 attached on its sides,
and having an upper horizontal zipper 311 and a lower horizontal
zipper 312 which provide convenient access to compartment 306 via
flap 308. Flap 308 may be opened to fold backpack carrying straps
216 into compartment 306 to be stored within the duffle bag, as
best seen in FIG. 11.
[0044] A third embodiment of a convertible bag 410 is shown in
FIGS. 12-15. Convertible bag 410 has a front end portion 414 and a
back end portion 412 which are both preferably of a circular shape,
although it will be appreciated that other shapes may be used.
Convertible bag 410 is shown in a compact storage configuration in
FIG. 12. In this configuration, bag 410 is adapted to be a
relatively flat, cylinder-shaped CD or digital media holder. Front
end portion 414 has a first storage compartment 420 which
essentially is a pouch formed by a flap 424 which may be opened or
closed via a zipper 426 which preferably is tracked around circular
flap 424. First storage compartment or pouch 420 is accessed by
opening zipper 426 and peeling back flap 424. Front end portion 414
has a backing panel 434 which preferably is in a corresponding
circular shape.
[0045] A carrying strap 442 is attached to backing panel 434.
Backing panel 434 is joined to back end portion 412 by means of a
main zipper 470 which tracks around the perimeter of front end
portion 414 and back end portion 412. As can be seen in FIG. 14,
pouch 420 may contain further storage compartments, such as in the
form of dividers 464 to separate disc media such as CD-ROMs or
DVDs.
[0046] In this embodiment, as best seen in FIG. 13, back end
portion 412 may include yet another storage compartment or pouch
420a. Similar to pouch 420 on front end portion 414, pouch 420a may
include a flap 424a which may be closed by a zipper 426a. Depending
on the needs of the end user, storage compartment 420a may include
dividers such as are shown in first storage compartment 420.
[0047] Convertible bag 410 may be converted to an expanded
configuration which is a carrying bag as shown in FIGS. 13-15. When
main zipper 470 is opened, front end portion 414 and back end
portion 412 are separated as the zipper is continued on flexible
track 474 which is terminated at a stop 476. Front end portion 414
and back end portion 412 form a second storage compartment 466 for
the material of an expandable portion 472 which is used to form the
expanded bag configuration as shown in FIGS. 14 and 15. When
expanded, expandable portion 472 forms a fabric enclosure 475
expanded out from storage compartment 466, with a cylindrical shape
and side wall 478.
[0048] Stop 476 is attached to the middle of the large side wall
478. As with the other preferred embodiments, the integrated zipper
configuration provides convenience in separating and rejoining
front end portion 414 and rear end portion 412 by keeping the
toothed tracks and slidable element of main zipper 470 engaged at
all times and by automatically drawing the end portions together
when closing the second storage compartment to form the compact
configuration of convertible bag 410.
[0049] Side wall 478 of the cylindrical enclosure 475 has a top
slit 484 which is sealed by a zipper 486 which allows access to the
expanded bag. Alternatively, the top of the cylindrical enclosure
475 may have a flap comparable to the U-shaped flaps in bags 10 and
210, or of any other desired shape.
[0050] The expanded bag configuration as shown in FIGS. 14 and 15
provides more storage capacity. Additional items may still be
stored in circular pouch 420 at front end portion 414. The fabric
enclosure 474 also has two reinforcement straps 488 which encircle
the outside of side wall 478. Reinforcement straps 488 are attached
to the ends of a carrying strap 494 which may be used to carry
convertible bag 410 in the expanded configuration.
[0051] It will be appreciated by those skilled in the art that
throughout this specification a variety of materials, preferably in
the form of fabric or pliable material, may be used in constructing
the various embodiments of the invention and that while panels
often are described, such panels may be formed by separate but
connected pieces or by a unitary piece encompassing several panels,
and that straps, fasteners and other components also may be made
from any suitable materials and in any of a variety of
configurations to suit the particular needs and requirements of an
end user. It also will be apparent that various modifications and
variations can be made in constructing and configuring the present
invention without departing from the spirit or scope of the
invention. Thus, the present invention is not limited by the
foregoing descriptions but is intended to cover all modifications
and variations that come within the scope and spirit of the
invention and the claims that follow.
