Description
FIELD OF THE INVENTION
[0001] This invention relates to a backpack having a detachable
wheeled frame, and more particularly to a wheeled backpack and
frame combination wherein the backpack and the frame include a
mechanism to attach the backpack to the frame.
BACKGROUND OF THE INVENTION
[0002] An increase in awareness of injuries resulting from carrying
heavy loads and a need for convertible luggage to meet traveler and
commuter demands have led to the development of backpacks with
wheels so that users may wheel their backpack behind them when it
is too heavy or inconvenient to carry on their backs.
[0003] For example, U.S. Pat. Nos. 5,749,503 and Des. 375,402
relate to luggage that may be converted and used as a
wheeled-suitcase, a backpack or a hand-carried bag. In addition,
U.S. Patent Application Pub. No. 2002/0162716 ("'716 application")
shows a backpack that may be attached to a collapsible carrier.
According to the '716 application, the backpack or the carrier may
have wheels.
[0004] Backpacks with wheels and a built in frame tend to be rather
uncomfortable for the wearer. One object of the present invention
allows the owner to remove the frame when wearing the backpack.
SUMMARY OF THE INVENTION
[0005] The objects of the invention can be attained and the
disadvantages of the prior wheeled backpack combinations can be
overcome by providing a backpack attachable to a wheeled frame,
comprising in combination, a backpack having a main compartment and
a wheeled removable frame. The backpack may also have a secondary
compartment for carrying the wheeled frame when not in use. The
backpack may further include a flap extending from one side of the
rear wall to the other side thereof. The flap is releasably secured
to the backpack on the other side using one or more fasteners. A
wheeled detachable frame carries the backpack, and has a base
portion on which the backpack sits, at least one vertical support
bar, a handle, and a pair of wheels. The frame includes a pair of
fasteners for attaching the backpack to the wheeled frame. The
first fastener is located on an upper portion of the frame, and
attaches to an upper position of the backpack. The second fastener
is located on a lower portion of the frame, and attaches to the
lower portion of the backpack. The flap holds the frame against the
backpack using snaps or similar fasteners and conceals the frame
when attached to the backpack.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] As shown in FIGS. 1-4, the backpack and collapsible frame
combination 8 of the present invention includes a backpack 10
releasably mounted on a collapsible wheeled frame 20. The backpack
10 includes a handle 11, a main compartment 12, a front compartment
13, shoulder straps 14 with clips 15, and a flap 16 with snaps 17
or other closures, such as a zipper, Velcro, clips, buttons, and
the like. The flap 16 covers a portion of the frame 20 when the
backpack 10 is attached thereto, for esthetic enhancement, but the
flap 16 may also be padded to improve comfort for the wearer. In
addition, the flap 16 helps to secure the backpack 10 to the frame
20. The backpack 10 may be made of nylon or some other durable
fabric or material, and can include several compartments and
pockets that close with zippers or flaps, to hold books, writing
instruments, calculators, cell phones, snacks and the like. The
main compartment includes front 50 and rear 52 walls, two side
walls, 54, 56 and top 58 and bottom 60 walls. The clips 15 and the
snap closures 17 may be any suitable fastening devices, such as
hooks, clips, snaps, Velcro or the like. The clips 15 and snaps 17
may be made from plastic, metal or any suitable material, such as
spring steel or brass.
[0014] As shown in FIGS. 4-5, the wheeled frame 20 includes a base
21, vertical support bars 22, horizontal support bars 23, a
retractable handle 24, an axle 25, wheels 26, fenders 27, a
pivoting attachment 28 with one or more fasteners 29, and
stabilizing feet 31. The wheeled frame 20 and its components may be
made from any suitable lightweight material or combination of
materials, for example, aluminum, plastic or the like, or a
combination thereof such that the frame 20 can support the weight
of a full backpack 10, while remaining lightweight enough to be
handled by a school-age child. The wheels 26 may be conventional
solid plastic or rubber wheels, or ball bearing and plastic wheels,
such as may be found on in-line skates.
[0015] Referring to FIGS. 3-5, when attached to the wheeled frame
20, the backpack 10 sits on the base 21. The rear wall 52 of the
backpack 10 rests against the front side of the vertical 22 and
horizontal 23 support bars. The backpack 10 is secured to the
wheeled frame 20 by securing the pivoting attachment 28 to the
backpack 10 with closures, such as snaps 29, that mate with
closures on the backpack 10. Preferably, there are two such
attachments, one on the upper portion of the frame 20, adjacent the
handle 24 on the frame 20, the other adjacent or included in the
base 21. The upper attachment 28 may be hinged or pivoted, and the
fasteners 29 attached thereto may be snaps or other fastening
devices, such as hooks, clips, Velcro or the like.
[0016] In another embodiment, shown in FIG. 6, the upper attachment
may be a strip of Velcro or snaps 34 placed directly on a
horizontal cross-piece or brace 23, as shown in FIG. 6. Velcro, a
well-known and readily available material, widely used in the
luggage industry, usually includes two opposed gripping pieces,
often in the form of a tape or ribbon, one side having hooks, and
one side having loops. Either side 34 can be attached to the
horizontal cross-piece 23, provided its mate gets attached to an
adjacent portion of the backpack 10, to help to hold the backpack
10 against the frame 20. The lower horizontal support 23 and the
base 21 may also include a Velcro attachment 34. As mentioned
above, other attachments may be used, including snaps 29.
[0017] The snaps 29 may be made from durable plastic or any
suitable metal, such as steel, brass or the like. Preferably, the
pivoting attachment 28 will include the male or female portion of a
snap 29, while the backpack 10 will have the male portion 29 of the
snap or Velcro (for example) in position to join with the one on
the attachment 28 to secure the upper portion of the backpack 10 to
the frame 20.
[0018] Likewise, the frame 20 has an attachment 28 to secure the
lower portion of the backpack 10 to the lower portion of the frame
20, or to the base 21 itself. As with the upper attachment 28, the
lower attachment 28 includes one side of a snap or Velcro pair 34,
while the backpack 10 has the other side, to provide a secure
attachment to the lower portion of the frame 20. Together, the
upper and lower attachments 28 releasably secure the backpack to
the frame 20, providing for easy removal by the user.
[0019] The optional flap 16 on the backpack 10 is wrapped around
the back side of the vertical 22 and horizontal 23 support bars,
and is secured to the backpack with snaps 17, Velcro, or other
suitable fastening devices. The backpack 10 is also secured to the
wheeled frame 20 by wrapping the shoulder straps 14 around the
upper horizontal support bar 23 and the vertical support bars 22,
and then fastening the clips 15 on the lower portion of the
backpack 10.
[0020] Still referring to FIGS. 4-5, the backpack 10 is detached
from the wheeled frame 20 by releasing the snaps 17 from flap 16 of
the backpack 10, so that the flap 16 can be opened, and by
releasing the snaps 29 so that the pivoting attachment 28 can be
hinged upward. The clips 15 are also released to unwrap the
shoulder straps 14 from around the vertical support bars 22. Once
the backpack 10 is removed from the wheeled frame 20, the flap 16
is refastened to the backpack 10 by snapping together the snaps 17
on each portion. The clips 15 are also refastened to reattach the
shoulder straps 14.
[0021] When not in use, the wheeled frame 20 may be collapsed by
retracting the handle 24 as low as possible into the vertical
support bars 22. The base portion 21 may be hinged or pivoted so
that it folds upward to become parallel with the vertical support
bars 22. Similarly, the stabilizing feet 31 may also be pivoted to
fold away into the base 21. The size of the wheeled frame 20 may be
further reduced by providing removable wheels 26 and fenders
27.
[0022] The folded wheeled frame 20 and its removable parts may be
placed in one of the compartments in the interior of the backpack
10 for easy carrying and concealment when not in use, or it may be
attached to the backpack 10 using optional Velcro or elastic straps
32. The detached wheeled frame 20 is preferably attached to the
backpack 10 on a portion away from the back of a user to avoid
discomfort, such as the front or side of the backpack 10.
[0023] While this invention has been described in terms of specific
embodiments, this invention, including this disclosure and appended
claims, is intended to be construed in accordance with the full
spirit and scope of the invention, including alternatives,
modifications, and equivalents apparent to those of skill in the
art.
