FIELD OF THE INVENTION
[0003] This invention relates generally to an enclosure for
containing a bicycle wheel. More specifically, the invention
relates to an enclosure, such as a wheel bag or hard shell
container that is removeably mountable to a bicycle for carrying
the bicycle wheel such as during transport of the bicycle.
BACKGROUND
[0004] Many types of rooftop bicycle carriers (or racks) require
the front wheel of a bicycle be removed when mounting the bicycle
on the carrier. The front wheel is typically stowed in the vehicle
or is secured to the rooftop carrier using a separate fixture that
clamps to the wheel at its axle. As can be appreciated, the wheel
may be dirty, especially if the wheel is from a mountain bike, and
putting a dirty wheel in the vehicle is often undesirable. The
separate wheel fixtures that mount directly to the carrier are also
often undesirable because they can be expensive and take up limited
rooftop space that could otherwise be used to carry additional
bicycles.
[0005] Several wheel holders have been proposed to stow the front
wheel while the bicycle is being transported on a rooftop carrier.
In U.S. Pat. No. 5,588,661 of Wolfe, a bracket is disclosed that is
affixed to the rear dropout of a bicycle frame. When the bicycle is
placed on the rooftop carrier, the axle of the front wheel is
secured into a slot provided in the bracket by tightening the
wheel's quick release mechanism. The bracket has several drawbacks.
First, it is not easily removable from the bicycle and is intended
to remain on the bicycle adding unnecessary weight. Second, since
the front wheel is supported at the axle on only one side of the
axle, the stress on the axle from the weight of the wheel and wind
resistance during transport could cause damage to the axle and the
wheel's hub.
[0006] In U.S. Pat. No. 5,779,119 of Talbot, a wheel holder is
disclosed that is secured onto the seatpost of a bicycle and
includes an extension leg with spaced fingers extending therefrom.
The fingers have slots formed in their distal ends and the slots
are adapted to receive the axle of the bicycle's front wheel. The
holder requires the use of a clamping mechanism to secure it to the
seatpost. While Talbot clamping mechanism may be effective in
attaching the holder to the bicycle's seatpost, it requires several
interconnected moving parts that increase the total cost to produce
the holder, especially when compared to a holder with an attachment
mechanism that does not include interconnected moving parts.
Further, since the fingers of the Talbot holder are shorter than
the radius of the front wheel, the extension leg of the holder must
be passed through the spokes of the intended bicycle wheel so that
the spaced slots can be aligned with the ends of the wheel's axles.
As can be appreciated, passing the extension arm through the spokes
with the slotted fingers that extend perpendicularly therefrom can
be awkward especially when the associated front wheel includes
closely spaced spokes. Finally, the design of the Talbot holder
requires the device to extend in a direction generally
perpendicular to the bicycle. Given this configuration, the wheel
and the end of the extension arm could interfere with the mounting
of additional bicycles onto an associated rooftop carrier,
especially when more than two bicycles are to be transported by a
single carrier.
[0007] Wheel bags for enclosing and carrying a bicycle wheel are
well known in the art. Typically, these bags are used to store a
bicycle wheel in a vehicle while the bicycle is being transported
either by an automobile or by way of commercial transportation such
as an airplane, bus or train. By enclosing the wheel in a bag, the
surfaces of the vehicle are protected from any dirt, grease and
grime that may be on the wheel. When transporting a bicycle on a
rooftop carrier, a person using a prior art wheel bag typically
places the bag in the automobile, whether on an unused seat or in a
cargo area of the vehicle, such as a trunk. As can be appreciated,
placing the wheel bag in the vehicle takes up cargo space,
especially if more than one wheel bag must be placed in the vehicle
and more than one person and bicycle are being transported.
SUMMARY OF THE INVENTION
[0008] In a first preferred embodiment, a bag for containing a
bicycle wheel and attaching to a bicycle is described. The bag
includes an enclosure sized to substantially contain a bicycle
wheel. The enclosure has at least first and second opposing faces.
A first connector is attached to the enclosure on or proximate the
first face at a first location. A second connector is attached to
the enclosure on or proximate the first face at a second location.
A third connector is attached to the enclosure on or proximate the
first face at a third location. Each location forms a corner of a
hypothetical triangle and each connector is adapted to securely
attach with a portion of the bicycle.
[0009] In a second preferred embodiment, another wheel bag for
carrying a wheel of a bicycle is described. The wheel bag comprises
a substantially fabric enclosure, and at least three strap
connectors attached to the enclosure. The enclosure includes a
closable opening through which the wheel is put into the bag. The
strap connectors include at least one strap and one or both of a
(i) buckle and (ii) hook and loop material. The strap connectors
are adapted to secure the enclosure to the bicycle.
[0010] In a third preferred embodiment, a method comprising
substantially enclosing a front wheel from a bicycle within an
enclosure, and securing the enclosure to the bicycle at two or more
locations is described.
[0011] Numerous other embodiments and variations of the embodiments
are also contemplated as is provided in this specification
including the appended claims and as would be obvious to one of
ordinary skill in the art with the benefit of this disclosure.

DETAILED DESCRIPTION
[0018] A wheel bag and a hard shell container for containing at
least one wheel of a bicycle and attaching to the bicycle for
transport are described. The bag or container is generally attached
to the frame of the bicycle in at least three locations that are
arranged in a pattern wherein all the locations are not located
along a common line. Accordingly, the bag or container does not
swing and pivot undesirably when the bicycle is being transported
at high speeds on top of a rooftop carrier of an automobile. A
shoulder strap and handle can also be provided for transporting the
wheel bag or container when it is not connected to the bicycle. In
one preferred embodiment, the wheel bag is attached to the frame
tubes of a bicycle, particularly, the top tube and the down tube,
although in variations and alternative embodiments, the wheel bag
can be attached to different frame tube combinations or it can be
attached to other elements of the bicycle such as, but not limited
to, the handlebar stem, the handlebar and the seatpost.
Terminology
[0019] The term "or" as used in this specification and the appended
claims is not meant to exclusive rather the term is inclusive
meaning "either or both".
The Wheel Bag
[0020] FIGS. 1 and 2 are illustrations of one preferred embodiment
of the wheel bag 100. The bag includes (i) a generally circular
enclosure 101 that generally corresponds to the size of the wheel
202 to be contained therein, and (ii) three primary connectors 112,
116, & 120 typically comprised of fabric straps that are
attached to a rear face 104 of the enclosure to secure the wheel
bag to a bicycle 200.
[0021] The enclosure 101 generally comprises front and rear faces
102 & 104 with a circumferential side 103 extending between the
faces along the periphery of the faces. In the preferred
embodiment, the faces are generally substantially fabric and in
some variations at least a portion of the fabric on each face
includes an elastic fiber such as spandex. The enclosure is
typically sized such that the front and rear faces elastically
expand when a wheel is placed therein causing the enclosure to be
conformal about the wheel. In other variations of the front and
rear faces, the fabric does not include spandex-type fibers to make
the enclosure elastically stretchable and the fabric can include
any suitable material, natural or synthetic, including, but not
limited to, nylon, rayon, polyester, and cotton. In yet other
variations, the faces could comprise a non-woven fabric similar to
a Tyvex-type material or they can comprise a flexible sheet
material such as translucent or opaque vinyl or neoprene. Finally,
the front and rear faces need not be circular or round but can be
square or rectangular or any other suitable shape.
[0022] The circumferential side 103 is typically made of a fabric
or flexible sheet material, which may or may not be elastically
stretchable. The width of the circumferential side is typically
about 1-3" depending on the type of wheel to be carried therein.
Generally, the circumferential side is sewn to the front and rear
faces, although it can also be attached to the faces by any other
suitable means including, but not limited to, adhesive bonding and
riveting. The circumferential side 103 is typically at least
partially bisected by a zipper 106, which is utilized to open or
close the enclosure. Preferably, the zipper includes two zipper
pull handles 126 that have holes passing therethough that can
receive the shackle of a lock 127, a strap, a chain, or a rope to
secure the zipper in the closed position. Depending on the
variation of the preferred embodiment, the zipper can extend
completely around the circumferential side such that the front and
rear faces can be completely separated from one another. In another
variation, the zipper does not completely encompass the entire
length of the circumferential side, wherein the front and rear
faces are fixedly joined by the portion of the circumferential side
without the zipper. In certain embodiments, the circumferential
side is not differentiable from the respective front and rear faces
wherein the zipper is attached to the periphery of the front and
rear faces.
[0023] A plurality of primary connectors 112, 116 & 120 are
positioned on the rear face 104 of the enclosure 101 and are
provided for attaching the wheel bag with a wheel 202 contained
therein to a bicycle 200. In one preferred embodiment, at least
three connectors are provided that are not linearly disposed such
that the location of each connector essentially forms the corner of
a triangle relative to the locations of the other connectors. By
using at least three connectors that are not all linearly disposed
relative to each other, the bag can be attached to the bicycle in a
manner that will not cause it to pivot about the connectors when
being subjected to the wind that is created during transport of the
bicycle at high speeds on top of an automobile. Additional
connectors 134 and 136 (as shown in FIG. 3) can also be provided to
further secure the bag to the bicycle.
[0024] Referring to FIGS. 3 and 4, the wheel bag is attached to the
frame of a bicycle 200 in such a manner that the first and second
connectors 112 & 116 are secured to the top tube 206 of the
bicycle and the third connector 120 is secured to the bottom tube
210 of the bicycle. This attachment configuration is merely
exemplary, and any numbers of other attachment configurations are
possible that will also adequately attach the wheel bag to the
bicycle. For instance, one connector can be secured to the seatpost
220, while the other two connectors are attached to one or both a
chainstay tube 214 or the down tube 210. Further, one or both of
the additional connectors 134 & 136 can be attached to the seat
tube 208. In another configuration, one connector could be attached
to the stem 222 or head tube 216, and one of the other connectors
attached to the top tube 206 and the final connector attached to
the down tube 210.
[0025] Referring to FIG. 2, the first and second of the illustrated
connectors 112 & 116 comprise straps with a proximal end sewn
to the rear face 104 of the bag and a distal end having a piece of
hook or loop piece of material 114 & 118 attached thereto. The
hook or loop material corresponds to a mating hook or loop material
piece 114 & 118 attached to the rear face. Accordingly, the
strap can be at least partially placed around the portion of the
bicycle to which it is to be attached and then secured to the rear
face by joining the associated hook and loop material pieces
together. The third connector 120 comprises straps that are sewn to
the rear face and are connectable by a buckle 122 with mating male
and female sections. The straps are placed around a portion of the
bicycle and hooked together. The straps can be of a fixed length or
they can be adjustable, such as illustrated in FIG. 2, wherein one
strap is looped through a slot 124 provided in one of the buckle
sections. The additional connectors 134 & 136 as shown in FIG.
3 are generally similar to the first and second connectors
comprising straps and hook and loop material, and can be used to
further secure the wheel bag to the bicycle as desired. Of course,
all the connectors can be of any suitable design and are not
limited to the specific examples discussed herein. For instance,
all three primary connectors can comprise buckles, or they can all
comprise straps with hook and loop material. Additionally, the type
of buckles can vary substantially as would be obvious to one of
ordinary skill in the art. Other variations of the connectors may
not use buckles or hook and loop material but rather buttons,
snaps, ties, or some other suitable means of connecting the bag to
the bicycle. Further, suitably configured clamps can be used in
place of the straps on one or all of the connectors.
[0026] The illustrated embodiment of the wheel bag includes a strap
handle 111 that can be utilized to carry the bag when it is off the
bicycle. Further, two shoulder strap loops 110 are provided on the
enclosure: one on the front face and one on the rear face. A
removable shoulder strap 108 can be attached to the loops to
facilitate the carrying of the wheel bag without the use of one's
hands. It is to be appreciated that in different variations and
other embodiments of the bag, different types of handles and
shoulder straps can be provided or they may not be provided at all.
In one variation, the strap of one of the three primary connectors
can also be used as a handle to carry the bag.
[0027] As illustrated in the cutaway section of FIG. 2, one or two
plastic pieces 130 & 132 can be provided proximate where the
center of the bag where the axles of a wheel 202 would protrude
from the wheel's hub 204 (See FIG. 4). Generally, the plastic
pieces are made of sheet nylon, polypropylene, polyethylene or any
suitable plastic and are mounted to the inside surfaces of the
front and rear faces 102 & 104 to protect the faces from being
punctured or otherwise damaged by the axle and/or quick release
skewers of the wheel's hub. The plastic pieces can be mounted to
the inside surfaces of the front and rear faces by any suitable
means such as, but not limited to, sewing and adhesive bonding. In
one embodiment, the plastic pieces are slid into fabric pockets
provided on the inside of the faces. In other embodiments, no
plastic pieces are utilized especially if the faces are comprised
of an abrasion or puncture resistant material, such as a heavy
nylon cloth.
An Alternative Embodiment Hard Shell Wheel Container
[0028] Referring to FIG. 5, an alternative embodiment hard shell
wheel container 300 is illustrated. Similar to the wheel bag
described above, the hard shell container encloses a wheel of a
bicycle and attaches to the bicycle to hold the wheel while the
bicycle is being transported, such as on a rooftop carrier.
Essentially, as illustrated, the container comprises front and rear
pieces 302 & 304 that are formed from polymeric sheet material
such as, but not limited to, ABS, nylon, polyethylene, PET, and
polypropylene are joined together to form a clamshell type
enclosure around a bicycle wheel. It is appreciated that the
interior of the container can be lined, at least partially, with a
resilient foam material to cushion the wheel, and prevent movement
of the wheel that could generate noise during the transport of the
wheel and container.
[0029] The front and rear pieces 302 & 304 of the container can
be fabricated by any suitable process including vacuum molding,
press forming, and injection molding. Typically, the two pieces are
joined together with three or more clamps 306 that are riveted,
bolted or boned to one or both of the pieces proximate the
periphery thereof. These clamps can be of any suitable
configuration as would be obvious to one of ordinary skill in the
art, but the illustrated clamps include a hooked tongue 308 that is
received into a slot (not shown) formed in the corresponding front
piece that acts to secure the two pieces together when the clamp is
engaged. It is appreciated that hook and loop material straps can
also be utilized in variations of the alternative embodiment
container to hold the two pieces together, wherein one of the hook
and loop material portions is attached to a strap that is secured
to one piece and the other of the hook and loop material portions
is attached to the other piece.
[0030] Like the preferred wheel bag, the hard shell container
attaches to the bicycle at three locations via connectors provided
on the rear face or proximate the rear face of the rear piece of
the shell. The container's connectors 310 can comprise connector
straps 312, with buckles 314a & b that are fed through a slot
316 in a fixture 318 that is riveted to the rear piece 304 of the
container as illustrated, or any other suitable type of connector
including clamps. It is appreciated that the straps with buckles
can be replaced with hook and loop straps. Further, a similar type
connector can be utilized with the wheel bag 100 described above,
wherein the slotted fixtures can be replaced with straps that are
sewn to the bag's rear face on either end to form slots there
between in which the connector straps with the buckles can freely
slide. When clamps are utilized the clamps can be mounted to the
rear face in such a manner as to permit the clamps to be
positionally adjustable on the rear piece thereby allowing the
container to fit bicycles and bicycle frames of differing sizes and
configurations. Generally, the straps and/or clamps are riveted on
to the rear piece, but they can be adhered to the rear face by any
suitable means in variations including bolting, bonding, and
sewing. Handles 322 or rings 320 for shoulder straps can also be
provided on one or both of the front and rear pieces.
A Method Of Using The Wheel Bag (Or Shell Enclosure)
[0031] Referring to FIG. 6, flow chart 400 describes the preferred
use of either a wheel bag or hard shell container 300 in
conjunction with a rooftop or similar rack for transporting a
bicycle on an automobile.
[0032] First, as indicated in block 402, the front wheel 202 of the
bicycle 200 is removed from the front fork 218 of the bicycle and
is typically set aside. Next as indicated in block 404, the bicycle
sans its front wheel is placed on the rooftop carrier. Typically,
the rear wheel 226 is placed in a track 250 provided on the carrier
and the dropout slots of the front fork are placed in a dummy axle
(not shown) on the carrier. A quick release cam bolt 256 or nuts
(not shown) are tightened to secure the front fork to the dummy
axle.
[0033] As indicated in block 406, the wheel is placed in the wheel
bag or hard shell container and the bag or container is closed to
contain the wheel. Typically, a wheel bag will be zipped shut. If
the zipper pull handles 126 have holes in them, the user can pass a
rope, a chain, the shackle of a lock 127, a twist tie or other
device through both the holes to help ensure that the zipper will
remain shut. With the hard shell container, the pieces 302& 304
of the container are typically clamped shut.
[0034] Next as provided in block 408, the wheel bag or container
with the wheel contained therein is attached to the bicycle 200.
Using the wheel bag 100 as illustrated in FIGS. 1-4, the user
aligns the primary connectors 112, 116 & 120 with particular
locations on the bicycle such as the bicycle frame tubes. The
straps of the primary connectors are then placed over the frame
tube or other component of the bicycle and secured, typically
through the use of hook and loop material or buckles. In FIGS. 3
and 4, the straps of the first and second connectors 112 & 116
are placed over and around the top tube 206 of the bicycle frame
and secured with hook and loop material, and the strap of the third
connector 120 is looped around the downtube 210, buckled and the
strap is tightened as necessary. Optionally, additional connectors
134 & 136, typically in the form of hook and loop material
straps can be looped around portions of the bicycle to further
secure the bag. The hard shell container 300 illustrated in FIG. 5
is connected to the bicycle in a similar manner.
[0035] Although the method of securing a bicycle 200 and its front
wheel 202 in a wheel bag or hard shell container to a rooftop
bicycle rack has been described with reference to the particular
order of operations illustrated in FIG. 6, the actual order of
operations can vary as would be obvious to one of ordinary skill in
the art. For instance, the wheel bag could be secured to the
bicycle before the wheel is placed in the bag. Further, the same
method may be applicable to other types of racks and accordingly,
the described method is not intended to be limited just to use with
rooftop racks but with any suitable type of rack where a wheel of
the bicycle must be removed before securing the bicycle in the
rack.
Other Alternative Embodiments And Variations
[0036] The embodiments of the wheel bag and hard shell container as
illustrated in the accompanying figures and described above are
merely exemplary and are not meant to limit the scope of the
invention. It is to be appreciated that numerous variations to the
invention have been contemplated as would be obvious to one of
ordinary skill in the art with the benefit of this disclosure. All
variations of the invention that read upon the appended claims are
intended and contemplated to be within the scope of the
invention.
[0037] For instance, any type of connectors that can securely
attach the wheel bag or container to the bicycle can be utilized.
Further, the types of connectors can be intermixed in any
particular embodiment of the wheel bag or container. For example,
one connector could comprise a clamp, while the other connectors
could comprise straps with hook and loop material or buckles.
Further, although the preferred embodiments utilize three primary
connectors located in locations that essentially form the points of
a triangle, embodiments that utilize four or more connectors are
also anticipated. The shape of the containers need not be round or
circular and they can be configured to contain additional items in
addition to the front wheel, such as tools or a second wheel.
