Description
TECHNICAL FIELD
[0001] The present invention relates generally to luggage and
portable clothes containers.
BACKGROUND ART
[0002] Luggage has been a standard way of transporting an
individual's belongs for many years. The capacity of a suitcase is
of course defined by its interior volume, and suitcases of large
capacity are often favored due to their large volume. However,
large suitcases present a problem when they are not in use, and the
owner wishes to store them. The very same large capacity which
makes them attractive for transporting goods, makes them take up a
large amount of space in a closet or storeroom. Thus, some
suitcases have been designed to collapse to a smaller configuration
when they are not in use. The simplest method of doing this is to
make the surrounding, shorter sides of the suitcase of flexible
material such as sturdy cloth, so that the sides can fold or pleat
into shorter lengths. This draws the larger side panels together to
lie in a shortened stack, which has reduced thickness and which can
then be easily stored.
[0003] However, this type of collapsible luggage has disadvantages
because without any stiffening elements in the surrounding sides,
packing may be difficult, since the exact full volume of the case
is difficult to determine, and the flopping sides may interfere
with packing operations.
[0004] Therefore, there is a need for a convertible suitcase, which
has sides which can be made rigid, when packing is performed, and
which can be made flexible again when the suitcase is desired to be
collapsed for storage.
DISCLOSURE OF INVENTION
[0005] Accordingly, it is an object of the present invention to
provide a suitcase whose volume can be reduced when not in use.
[0006] Another object of the invention is to provide luggage which
has surrounding sides which can be made rigid to aid in packing,
but can be made flexible when storage is desired.
[0007] And another object of the invention is to provide luggage in
which stiffening elements are attached to the remainder of the
case, and are not easily lost.
[0008] Briefly, one preferred embodiment of the present invention
is a luggage bag which is convertible from a collapsed
configuration to an expanded configuration which is self-supporting
to maintain an expanded interior volume. This bag includes a bottom
panel, a top panel, a number of flexible, non-self-supporting side
panels, and at least one self-supporting side support panel, which
is moveable from a prone position to an upright position, to
support at least one of the flexible side panels and maintain an
expanded interior volume within the luggage bag.
[0009] An advantage of the present invention is that the
surrounding sides are convertible from rigid to flexible by using
support panels.
[0010] Another advantage of the invention is support panels are
attached to the luggage, and are not easily lost.
[0011] And another advantage of the invention is the luggage
converts easily and quickly from collapsed to rigid-sided.
[0012] These and other objects and advantages of the present
invention will become clear to those skilled in the art in view of
the description of the best presently known mode of carrying out
the invention and the industrial applicability of the preferred
embodiment as described herein and as illustrated in the several
figures of the drawings.

BEST MODE FOR CARRYING OUT THE INVENTION
[0021] A preferred embodiment of the present invention is a
collapsible luggage bag which is convertible from flexible to rigid
and vice versa. As illustrated in the various drawings herein, and
particularly in the view of FIG. 1, a form of this preferred
embodiment of the inventive device is depicted by the general
reference character 10, and will be referred to as convertible
luggage bag 10. FIGS. 1-6 and 7 show the stages of assembly
involved in converting the luggage bag from a flattened
configuration which flexible sides and minimal volume (FIGS. 1 and
2), to the fully assembled configuration having rigid sides, and
which encloses an expanded interior volume without the interior
support of contents (FIGS. 5 and 6).
[0022] FIGS. 1 and 2 show the luggage 10 which has been flattened
to its most compact configuration 12. The inventor estimates that
the collapsed configuration volume is as little as 1/6 of the
expanded configuration volume. Referring now also to FIG. 3, the
convertible luggage 10 generally includes a top side panel 14, a
bottom side panel 16, a top panel, also known as the lid 18, bottom
panel 20, an inner side panel 22, inner being referenced from the
hinge edge 24, and an outer side panel 26. These top side panel 14,
bottom side panel 16, inner side panel 22 and outer side panel 26
are all of flexible material 27, such as cloth, which is
non-self-supporting, or non-rigid. In this description, the term
"non-self-supporting" is used to mean that such material is
incapable of standing up vertically under the force of gravity
without exterior support. Material that is "self-supporting" will
be understood to be rigid or semi-rigid.
[0023] FIG. 1 also shows an extendable handle 28 including
extension tubes 30, and mounting bracket 32, which is attached to
the bottom panel 20 by any convenient method, such as rivets or
even snaps, if the bracket is to be made removable. At the bottom
side panel 16, there is a wheel assembly 34, including wheels 36
which are held in place by a wheel bracket 38. The wheel bracket 38
is attached to the bottom side panel 16 or bottom panel 20 again by
any conventional fasteners, including rivets or snaps. The wheel
bracket 38 also optionally includes sockets 40, into which prongs
92 of a support handle 90, described below, may be inserted. An
optional band 42, perhaps made of elastic, is also shown, which may
help to maintain the luggage 10 in a minimal volume configuration
12. A zipper 44 is positioned around three sides of the lid 18,
these three sides excluding the hinge edge 24.
[0024] FIG. 3 shows the luggage 10 in which the zipper 44 has been
unzipped to allow the lid 18 to pivot along the hinge edge 24,
revealing the interior of the luggage 10. A side support panel 46
is shown being put in position as indicated by the directional
arrow 87. This side support panel 46 is made of light-weight,
self-supporting material such as plastic, and may be enclosed in a
fabric pouch 48, in order to easily attach fasteners, etc.
Reference is now made also to FIG. 7, which shows the opened
luggage 10 in more detail, but with the wheel bracket and support
handle removed for ease of viewing. In FIG. 3, only one side
support panel 46 is shown, but it is understood that at least one
more side support panel is expected to be used in typical
applications. In FIG. 7, one side support panel 46 is shown in
transition from the prone position 70 to the upright position 62,
while a second side support panel 46 is shown lying down in the
prone position 70.
[0025] First considering the side support panel 46 closest to the
hinge edge 24, it has an inner edge 50 and an outer edge 52. Strap
hinges 54 are part of straps 56 which extend onto some portion of
the outer side 58 (see FIG. 4). Generally the side support panel 46
has an inner side 60 which will face the inner side panel 22 when
the side support panel 46 is in its upright position 62 adjacent to
inner side panel 22, as seen in FIG. 4. The straps 56 preferably
have a fastener 64 which engages a fastener mating portion 66 on
retaining straps 68 which are attached to the inner side panel 22
near the hinge edge 24. The straps 56 serve to maintain the side
support panels 46 within the luggage interior even when not being
used as supports. They also act as a support hinge 72 to allow
movement of the side support panels 46 from an upright position 62
to a prone position 70 and vice versa. By placing these side
support panels 46 in an upright position 62, the luggage bag 10 is
converted to an extended configuration 13, in which the luggage bag
10 maintains an expanded interior volume 11, allowing for easy
packing of articles. When the side support panels 46 are replaced
in their prone position 70, the non-self-supporting side panels 14,
16, 22, 26 are allowed to fold and collapse, and the luggage bag 10
resumes it compact configuration 12.
[0026] In addition to these side support panels 46, there are
preferably a top support panel 74 and a bottom support panel 76,
which may be contained in a top pouch 78 and a bottom pouch 80
respectively. These top and bottom pouches 78, 80 may have
fasteners 82 to close the pouches 78, 80 and help retain the
support panels 74, 76, or the support panels 74, 76 may be
permanently fixed in position. A preferred feature of these pouches
78, 80 is a pouch hinge area 84, which may actually be the fabric
of the top side panel 14 and bottom side panel 16, the purpose
being to allow the top and bottom support panels 74, 76 to fold
from a prone position into an upright position 70, as indicated by
the arrows 86 in FIG. 3. Alternately, the top and bottom support
panels 74, 76 may be removable from the pouches 78, 80 to allow
collapsing, but this is less preferred because of the danger that
they may be eventually lost. If they are permanently retained in
the pouches 78, 80, this danger is reduced.
[0027] The luggage 10 also optionally includes an elastic retainer
86 having a release snap 88, for retaining objects near the bottom
panel 20. As shown in FIG. 3, one such article is a support handle
90, mentioned above, having prong portions 92 which are configured
to fit into sockets 40 in the wheel bracket 38 (see FIG. 4). Once
the support handle 90 has been installed, (see FIG. 5), the handle
has support feet 94 which aid in steadying the luggage bag 10 when
it is placed in an upright position (see FIG. 6). The support
handle 90 may also have a grip portion 96 and may have additional
fasteners such as a Velcro.RTM. strip (not visible) which aids in
maintaining its position on the bottom side panel 16.
[0028] Thus, to convert the convertible luggage bag 10 from a
collapsed configuration 12 to an extended configuration 13, as in
FIGS. 1-6, first, the band 42 is removed and the zipper 44 is
unzipped. The lid 18 is then opened. The top and bottom support
panels 74, 76 are pivoted into upright position 62, as indicated by
arrows 87 in FIG. 3. The side support panels 46 are pivoted into
upright position 62 and the fasteners 64, 66 engaged. The support
handle 90 is removed from the luggage bag 10 interior and its prong
portions 92 engaged with the sockets 40 on the wheel bracket 38.
The luggage bag 10 is then fully assembled and ready to receive
articles.
[0029] It will be understood by one skilled in the art that the
particular embodiment has been presented by way of example only,
and not limitation. Many variations are possible in the number of
sides of the bag, the height, width and depth of the bag, and the
placement and number of side support panels.
[0030] Thus, the breadth and scope of the invention should not be
limited by any of the above described exemplary embodiments, but
should be defined only in accordance with the following claims and
their equivalents.
INDUSTRIAL APPLICABILITY
[0031] The present convertible luggage bag 10 is well suited for
application in transporting personal items by providing an
expansive volume capacity, and yet collapsing to a very small
volume for storage.
[0032] In converting the convertible luggage bag 10 from a
collapsed configuration 12 to an extended configuration 13, the
band 42 is first removed and the zipper 44 is unzipped. The lid 18
is then opened. The top and bottom support panels 74, 76 are
pivoted into upright position 62, as indicated by directional
arrows 87. The side support panels 46 are pivoted into upright
position 62 and the fasteners 64, 66 engaged. By placing these side
support panels 46 in an upright position 62, the luggage bag 10 is
converted to an extended configuration 13, in which the luggage bag
10 maintains an expanded interior volume 11, which allows for easy
packing of articles.
[0033] The support handle 90 is removed from the luggage bag 10
interior and its prong portions 92 engaged with the sockets 40 on
the wheel bracket 38. The luggage bag 10 is then fully assembled
and ready to receive articles.
[0034] When the side support panels 46 are replaced in their prone
position 70, the non-self-supporting side panels 14, 16, 22, 26 are
allowed to fold and collapse, and the luggage bag 10 resumes it
compact configuration 12.
[0035] The uses of this collapsible bag 10 are numerous, and can be
used anywhere conventional luggage may be used, but can be easily
and conveniently stored by the owner when not in use. In addition,
their reduced volume while collapsed makes shipping and storage of
the items much easier and less costly, as they may take up less
space in warehouses and store displays, and less space in trucks
while in shipment.
[0036] For the above, and other, reasons, it is expected that the
convertible luggage bag 10 of the present invention will have
widespread industrial applicability. Therefore, it is expected that
the commercial utility of the present invention will be extensive
and long lasting.
[0037] While various embodiments have been described above, it
should be understood that they have been presented by way of
example only, and not limitation. Thus, the breadth and scope of a
preferred embodiment should not be limited by any of the above
described exemplary embodiments, but should be defined only in
accordance with the following claims and their equivalents.
