Description
RELATED APPLICATION
[0001] This application claims priority from provisional application
Serial No. 60/262,734, filed Jan. 19, 2001.
BACKGROUND OF THE INVENTION
[0002] The present invention relates generally to toy foot scooters.
More particularly, the present invention relates to a trick bar
for use on such foot scooters.
[0003] Foot scooters are devices which include a foot platform
having a pair of in-line wheels for moving the platform, and a post
extending upwardly from one end of the platform for the attachment
of hand grips which aid the user in maneuvering the foot scooter
device. Recently, such foot scooters have had a tremendous market
impact. They are particularly attractive amongst children and teenagers.
As these scooters have become popular, many suppliers have begun
to introduce various accessories for the foot scooters, including
flashing wheels, shoulder straps, etc.
[0004] A particular company recently came out with an accessory
item called the "wheelie bar", which is designed to fit
or attach to the rear end of the scooter for the rider to step on
as he or she wishes to conduct or perform tricks while riding the
scooter. However, this "wheelie bar" has been found to
be limited in its use due to several design flaws. The accessory
has insufficient body length which triggers unwanted or unplanned
braking of the scooter as the foot often applies force to the bar
and brake covering the rear wheel simultaneously. Also, the number
of tricks that can be performed using the accessory are limited
as there is a very limited time of suspension of the front wheel
prior to a complete stop, unless the rider is extremely proficient.
Moreover, the accessory has a limited application as it has been
designed to be attached to only one particular brand of foot scooter.
[0005] Accordingly, there is a need for a trick bar accessory which
can be attached to any number of foot scooters. What is also needed
is such a trick bar accessory which increases the amount of time
the front wheel is suspended, while enabling the rider to perform
more tricks without unwanted or unplanned braking of the foot scooter.
The present invention fulfills these needs and provides other related
advantages.
SUMMARY OF THE INVENTION
[0006] The present invention resides in a trick bar or a foot scooter
which enables the rider to perform tricks without unwanted or unplanned
braking of the foot scooter, and which also enables the front end
of the foot scooter to be raised to differing heights. The trick
bar generally comprises a pair of parallel elongated support arms
each having a first end attached to a rear end of the foot scooter,
and an elevated second end. A foot bar extends across the second
ends of the support arms. A wheel is supported by the support arms
intermediate the first and second ends thereof so as to rest a distance
above the ground on which the foot scooter rests. Upon application
of downward pressure on the foot bar, a front end of the foot scooter
raises off the ground and the trick bar wheel contacts the ground
to permit the rider to perform tricks.
[0007] The support arms are generally curved in configuration,
and typically pivotally attach to the foot scooter so as to be folded
over the foot scooter. Each support arm includes a stop that is
configured to contact the foot scooter in order to limit the downward
pivoting range of the support arms, particularly during use of the
trick bar.
[0008] The wheel is rotatable about an axle which extends across
the support arms intermediate the first and second ends thereof.
The axle is configured so as to be removable from the support arms
for changing the wheel with replacement wheels which may differ
in size. The axle may support a wheel which is positioned between
the support arms, or extend beyond the support arms and support
two wheels positioned without the support arms.
[0009] The support arms typically include a series of apertures
which permit the axle to be moved between positions along the support
arms, which affects the front wheel lift of the foot scooter when
tricks are performed. The support arms include reinforcement areas
substantially surrounding the axle to accommodate the forces concentrated
around the axle while tricks are performed.
[0010] Other features and advantages of the present invention will
become apparent from the following more detailed description, taken
in conjunction with the accompanying drawings which illustrate,
by way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] As shown in the drawings for purposes of illustration, the
present invention is concerned with a trick bar for a foot scooter,
generally referred to by the reference number 10 in FIGS. 1 and
4-6, and by the reference number 12 in FIGS. 2 and 7-9, and by the
reference number 14 in FIGS. 3 and 10-12. In each of the illustrated
embodiments, functionally equivalent components are given the same
reference number.
[0028] Referring to FIGS. 1-3, the trick bars 10-14 include first
and second support arms 16 and 18 having a generally curved configuration
so that a first end 20 lies lower than a second end 22 of the support
arms during use. The support arms 16 and 18 are placed generally
parallel to one another. A foot bar 24 extends across the second
ends 22 of the support arms 16 and 18. Although not limited to such,
typically the foot bar 24 is interconnected between the second ends
22 of the support arms 16 and 18 by way of screws 26 threaded through
apertures formed in the second ends 22 and into the foot bar 24.
The foot bar 24 is placed at the elevated second ends 22 to provide
lift, as will be more fully described herein.
[0029] A series of apertures 28 are formed in the support arms
16 and 18 intermediate the first and second ends 20 and 22. A wheel
axle 30 is insertable into or otherwise alignable with the wheel
apertures 28. As illustrated in FIG. 1, the axle 30 may extend through
the apertures 28 so that a pair of wheels 32 may be placed on the
axle 30 and reside without the support arms 16 and 18. Typically,
the axle 30 is removable so that it can be positioned through any
of the aligned apertures 28 so as to move the position of the wheels
32. Preferably, a screw 34 or the like is partially inserted into
the wheel axle 30 so as to removably hold the axle 30 in place.
[0030] With reference to FIG. 2, the axle 30 may only extend between
the support arms 16 and 18 and support a single wheel 32 therebetween.
The axle 30 is preferably removable from the support arms 16 and
18, so as to enable the user of the trick bar 10-14 to place wheels
32 of differing sizes, as illustrated in FIG. 3, or position the
axle 30 and wheels 32 at different points along the length of the
support arms 16 and 18.
[0031] The support arms 16 and 18 include an area of reinforcement
36 surrounding the wheel axle apertures 28. Although this can be
done in a variety of ways, typically, the support arms 16 and 18
are thicker in width around the apertures 28 to prevent structural
failure due to the forces concentrated around the wheel axle 30
during use. As illustrated in the accompanied drawings, the support
arms 16 and 18 themselves may be designed such that they are reinforced
along a substantial length thereof. This can be done by creating
an-I-beam structure along the length of the support arms 16 and
18, or strategic points thereof which are subject to the greatest
amount of stress. This I-beam structure is formed by configuring
the support arms 16 and 18 such that a top and bottom edge 40 and
42 are of a greater width than a central portion 44 of the support
arms 16 and 18. Alternative reinforcement designs are possible as
well, such as a C-shape tube, tubular support arms, or any available
method and design which would adequately reinforce the support arms
16 and 18 so as to resist bending and breaking by the weight and
pressure placed thereon during use.
[0032] A support axle 46 is removably inserted through apertures
formed adjacent to the first ends 20 of the support arms 16 and
18. The support axle 46 extends through a rear wheel 48 of the foot
scooter 50. The trick bar 10-14 extends from this point of attachment
rearward from the foot scooter 50. By attaching the trick bar 10-14
of the present invention to the rear wheel 48 of the foot scooter
50, the trick bar 10-14 can be attached to any existing model of
foot scooter 50. The support arms 16 and 18 are of a sufficient
length to adequately remove the foot bar 24 from a foot brake 52
of the foot scooter 50, so as to prevent a rider from accidentally
pressing on the foot brake 52 instead of the foot bar 24. The longer
body length of the support arms 16 and 18 also allows the rider
to properly level or maintain his or her balance while performing
a trick. Due to the increased balance and lessened likelihood of
inadvertently pressing the brake 52, the trick bar 10-14 of the
present invention is safer than the presently existing trick bar.
The rotatable wheel or wheels 32 positioned on the trick bar 10-14
also enable the rider to roll extra distance while performing the
tricks.
[0033] Referring now to FIGS. 14 and 15, the first ends 20 of the
support arms 16 and 18 include inwardly directed ledges or flanges
54 which are configured to contact a platform or frame 56 of the
foot scooter 50 when the trick bar 10-14 is in its extended position
for use. Thus, as pressure is applied downwardly on the foot bar
24, the ledges 54 apply pressure to the platform 56 of the foot
scooter 50, facilitating the lifting of a front end 58 of the foot
scooter 50, as will be described more fully herein.
[0034] Preferably, the support axle 46 is pivotally attached to
the rear wheel 48 of the foot scooter 50 so that the trick bar 10-14
can be folded over and onto the foot scooter 50 for compact storage
and transportation, as illustrated in FIG. 15. Typically, foot scooters
50 have a front end 58 which can be compacted and pivoted over onto
the platform 56. Having the ledges 54 extend only from a bottom
portion of the first ends 20 permit the trick bar 10-14 to be folded
over onto a top surface of the platform 56, while providing adequate
support to the trick bar 10-14 during use. Thus, the inwardly directed
ledges 54 connect as a hinge. The ledges 54 also cause the trick
bar 10-14 and associated wheel 32 to be raised from the ground surface
that the foot scooter 50 rests upon, by providing leverage when
the foot bar 24 is pressed downwardly. The fact that the inwardly
directed ledges 54 extend only at the base of the support arms 16
and 18, and not at the top portion thereof, the trick bar 10-14
can be folded upon the foot scooter 50 for storage while not interfering
with the folding and compactness provided by the foot scooter design
itself, as illustrated in FIG. 15.
[0035] Referring now to FIGS. 4-6, a foot scooter 50 is illustrated
having the trick bar 10 of FIG. 1 attached thereto. In FIG. 4, the
foot scooter 50 is resting or rolling upon level ground, with the
trick bar 10 elevated with respect to the ground. Upon applying
downward pressure to the foot bar 24, while simultaneously pulling
up the front end 58 and front wheel 60 of the foot scooter 50, the
front wheel 60 rises from the ground and the wheel 32 of the trick
bar 10 contacts the ground. The rider is then able to perform "wheelies",
spins, or other tricks. It will be noted by the reader that by positioning
the wheels 32 at different aligned wheel apertures 28, the front
end 58 of the foot scooter 50 can be increasingly or decreasingly
raised from the ground 62. Thus, with the wheels 32 in the forward-most
position, as illustrated in FIG. 6, the front wheel 60 of the foot
scooter 50 is only allowed to rise from the ground a certain distance.
However, by repositioning the wheels 32 towards the second end 22,
as illustrated in FIG. 5, the front wheel 60 of the foot scooter
50 is permitted to rise a greater degree from the ground. The size
of the wheels 32 attached to the trick bar 10 can also adjust the
height at which the front end 58 of the foot scooter 50 will rise.
For example, a larger wheel 32 will only allow the front end 58
of the foot scooter 50 to rise to a very limited degree, while a
much smaller wheel placed in the same position will allow the front
end 58 of the foot scooter 50 to rise higher. Thus, riders of various
levels can adjust the trick bar 10-14 to meet their capabilities.
Also, use of the tandem-wheel configuration trick bar 10 allows
the invention to be used as a training wheel for novice scooter
riders. As the wheel 32 is rotatable about axle 30, the rider is
more easily allowed to continue in a forward direction while performing
the tricks. Aside from permitting the rider to perform tricks which
might not otherwise be possible, the additional wheel 32 presents
a safety feature.
[0036] With reference to FIGS. 7-9, the same concepts described
above are shown with the trick bar 12 attached to the foot scooter
50. This trick bar 12 includes a single wheel 32 positioned between
the support arms 16 and 18. Such could be used for a rider of intermediate
capabilities. As illustrated in FIGS. 8 and 9, by adjusting the
position of the wheel 32 between aligned wheel apertures 28, the
rider is allowed to control the degree that the front end 58 of
the foot scooter 50 rises from the ground 62. Whereas the trick
bar 10 having two wheels 32 may be cumbersome in certain tricks,
the single wheel trick bar 12 permits the intermediate rider to
perform additional tricks.
[0037] Referring now to FIGS. 10-12, the trick bar 14 of FIG. 3,
is attached to the foot scooter 50. This trick bar 14 also has a
single wheel 32 positioned between the support arms 16 and 18, but
the wheel 32 is much smaller than the wheel of FIGS. 7-9. Therefore,
an advanced rider can use this configuration to raise the front
end and wheel 58 and 60 to a very large degree from the ground 62.
Thus, it will be noted that the front end 58 of the foot scooter
50 is much more elevated from the ground 62 in FIG. 11, than in
FIG. 8. Similarly, by positioning the wheel 32 and axle 30 and the
rear most wheel apertures 28, the front end 58 of the foot scooter
50 is allowed to rise to an even greater degree, as illustrated
in FIG. 12. Thus, advanced riders are enabled to perform tricks
which would not otherwise be possible with other configurations.
[0038] Thus, riders of various levels can adjust the trick bar
10-14 to meet their capabilities. This is done simply by the placement,
and size of the single or dual wheel configuration. The invention
can thus be sold as a kit, wherein the novice scooter rider installs
the longer wheel axle 30 which supports two wheels 32 outside of
the support arms 16 and 18, which can then be changed for the single
wheel trick bar 12 configuration illustrated in FIG. 2, and eventually
the small wheel 32 configuration illustrated in FIG. 3 as the rider's
capability increases. The axles 30 and wheels 32 can also be sold
separately to meet the individual needs of the consumers.
[0039] Although several embodiments have been described in detail
for purposes of illustration, various modifications may be made
without departing from the scope and spirit of the invention. Accordingly,
the invention is not to be limited, except as by the appended claims.
