Description
RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Pat.
Appl. Ser. No. 61/331,673, filed on May 5, 2010, the contents of
which are incorporated by reference herein.
FIELD OF THE INVENTION
[0002] The current invention relates to the field of video game
accessories, more specifically to an inflatable vehicle that is
adapted to receive a WII game controller.
BACKGROUND OF THE INVENTION
[0003] For many years, video games have been a popular form of
entertainment for players of all ages and skill levels. Since the
earliest games have first been introduced to the public, there has
been a continuous effort on the part of game developers to produce
games having a realistic feel. In this regard, the NINTENDO WII
presents a vast improvement to the state of the art.
[0004] WII games are played by means of a WII controller. The WII
controller uses accelerometer and optical sensor technology to
sense the motion imparted by a player to accordingly manipulate
images displayed on a game display screen. Players of WII games use
the WII controller to simulate the various motions associated with
all types of games and sports such as, for example, bowling, golf,
baseball, basketball, golf, tennis, boxing and car racing.
[0005] The closest that developers have come to simulating a
driving experience is through the means of a steering wheel device,
which houses a WII controller, The steering wheel is not connected
to any supporting structure, but rather is it held in a player's
hands and rotated about its axis by a player.
[0006] Because of several factors, the WII steering wheel does not
successfully replicate the driving experience. First, a player sits
in his/her normal surroundings--which is very different from
sitting in the confines of a vehicle. Moreover, the steering wheel
must be held with two hands at all times because it is not attached
to any supporting structure.
[0007] The concept of an inflatable kart for use by a player during
video game play already exists in a product identified as the
WINFUN Plug and Play kart. The WINFUN game does not simulate the
real world experience of the WII game in that it does not sense the
movement of the steering wheel as a real parameter in the skill of
the driver operating the simulated automobile. Instead of a
rotatable steering wheel that is adapted to receive a game
controller, the WINFUN product comprises a hard-wired control
having buttons to control movement on a screen. In fact, as a
consequence of the real life action achieved with the current
invention, the inventors have found that it is important to ensure
that the steering column be securely attached to the housing
because of the need for such connection to be maintained and to
provide an accurate driving experience. Such secure attachment was
not required with the WINFUN product.
SUMMARY OF THE INVENTION
[0008] The invention is directed to a realistic-appearing
inflatable vehicle, in which a player sits when playing a driving
game. The steering wheel (or handle bar) is provided with one or
more compartments for receiving a WII or a similar game
controller(s). A player sits in the vehicle seat while playing the
game and turns the steering wheel in much that same way as a person
would while driving a real vehicle. The controller is secured
within the steering wheel and is largely obscured from a player's
view. This adds to the authenticity of the experience.
[0009] Additionally, a steering wheel attachment mechanism for
attaching the steering wheel to the housing of the kart is
reinforced above and beyond a conventional connection in toy karts
to ensure that there is not physical separation between these
elements as the game is being played. Because of the intense
experience achieved with the WII game, such secure connections
ensure the game is played without it failing as the driver becomes
more and more excited.
[0010] The invention thus allows for players to experience
realistic driving conditions while playing a WII driving game
thereby enhancing the overall game experience.
[0011] The vehicles are inflatable and therefore compactly
transported and stored. Once inflated, they are light and portable.
In addition, they may be easily deflated for convenience of
storage.

DETAILED DESCRIPTION OF THE INVENTION
[0027] Embodiments of the present invention will now be described
with reference to the above-identified figures. However, the
drawings and the description herein of the invention are not
intended to limit the scope of the invention. It will be understood
that various modifications of the present description of the
invention are possible without departing from the spirit of the
invention. Also, features or steps described herein may be omitted,
additional steps or features may be included, and/or features or
steps described herein may be combined in a manner different from
the specific combinations recited herein without departing from the
spirit of the invention, all as understood by those of skill in the
art.
[0028] FIG. 1 shows an inflatable race car that is fashioned to
resemble a real-life car having wheels 10, a front bumper 12, a
rear bumper 14, doors 16, a dashboard 28 and a steering wheel 22.
The interior of the car has a floor surface 18 and a seat 20, which
is positioned near the rear end of car. An underlying chassis 19
supports the structural elements of the car.
[0029] Toward the front end of the car, there is a front body
structure 24, which arises from floor surface 18. The front body
structure 24 serves as a front body of the vehicle and as a
steering wheel attachment structure. Front body is an elevated
structure 24 having a first end (base) rising from the floor
surface 18 and a second end forming a gradual peak 25. Two
sidewalls 30a, 30b descend from peak 25 toward each side of the car
and are each flanked at their base by an exposed floor surface.
Another two walls slope frontward and rearward. A frontward wall 26
descends from peak 25 facing the exterior of the car ("exterior
wall") and a rearward wall 28 faces the interior of the car
("interior wall"), The exterior wall 26 is designed to look like
the front hood of a race car--having a gradual downward slope. The
interior wall is a dashboard 28 and it serves as a location for
mounting the steering wheel 22. Dashboard 28, is provided with an
attachment mechanism for pivotably attaching a steering wheel
22.
[0030] The various structural elements, such as, for example, the
chassis 19, wheels 10, seat 20 and front body 24 each comprise a
respective-shaped structures made of PVC or such similar material.
The respective structures take shape when they are fully inflated
with air. It will be understood that some of the structures may be
independently formed and require to be separately inflated,
whereas, other structures may be in fluid communication with each
other such that air is shared between two or more structures.
[0031] As shown in FIG. 2, during play, a player sits on seat 20
resting his/her feet on the floor and naturally grasps the steering
wheel 22 in the same manner as one would when driving a real-life
vehicle. The motion of the steering wheel is sensed in the WII game
by line of sight communication between the controller held in the
steering wheel 22 and a console located in the proximity of a
screen 33. The motion of the steering wheel is, thus, sensed as
real life motion to control images displayed on a display device.
There are other motion sensitive driving games which can sense
movement of a specific game controller and such games can
advantageously use this invention.
[0032] In a preferred embodiment of the invention, the car is
designed to accommodate both adults and children alike. For
example, to best accommodate players of wide ranging heights, the
car is designed with an elongated foot resting area 31 (best shown
in FIG. 7)--for receiving a player's foot in any location along the
elongated area 31. In a preferred embodiment, foot resting area 31
is an exposed floor surface 18 on either side of front body
structure 24. A player sitting on seat 20 places his/her feet in
foot resting area 31. The legs of an adult or tall player may
extend entirely into foot resting area 31 (as shown in FIG. 2),
whereas the legs of a child might extend only partway into foot
resting area 31. In addition, the car design also allows for a
child to sit directly on the floor 18 in front of seat 20 to better
reach steering wheel 22.
[0033] The distance between seat 20 and front body structure 24 is
preferably from about 200 mm to 250 mm. This distance was found by
the inventor to best accommodate the fullest range of player
heights. The width of seat 20 is from about 330 mm to 400 mm.
[0034] Furthermore, steering wheel 22 may be adjusted (e.g. between
the two positions depicted in FIG. 6) to tailor steering wheel
accessibility to players of various heights. A short player, for
example, will move the steering inward (toward him/herself) for
ease of reach, whereas a taller player might tilt the steering
outward (away from him/herself).
[0035] In addition to adjustability, the steering wheel is securely
mounted such that it is able to withstand forces exerted by an
adult playing the WII game. To that end, the various components
that comprise the steering wheel attachment and locking mechanism
(described in more detail below) is reinforced and designed to be
of high integrity.
[0036] In order to support adults, a thick PVC (or a material
similar thereto) material is used. In a preferred embodiment, the
PVC is double the thickness of inflatable pool toys.
[0037] FIGS. 3A and 3B show a steering wheel attachment mechanism
according to an embodiment of the invention. As shown, a base
member 40 is securely attached to the dashboard 28 of front
structure 24. Preferably, a permanent glue is utilized to attach
base member 40. Most preferably the permanent glue is of a kind
that possess elastic qualities after being fully dried. Base 40 is
adapted to receive a wheel attachment mechanism for attaching a
steering wheel. For example, in a preferred embodiment, a collar 42
attached to base 40 is sized and shaped to be inserted into a
complementary tubular steering column cap 44. Steering column cap
44 is designed to be tightly secured to collar 42. To that end, in
a preferred embodiment of the invention, collar 42 comprises one or
more attachment tabs 130 (best seen in FIG. 4A) helping to ensure a
secure connection between the steering column and base 40 or body
of the kart. This will be described in more detail below with
reference to FIGS. 4 and 5.
[0038] As an added security measure and to ensure proper alignment,
in an embodiment of the invention, tab 46 is vertically slidably
connected to column cap 44, which moves into a corresponding slot
48 in collar 42. Tab 46 slides upward and downward (i.e. toward and
away from the collar as oriented in FIG. 3a)--but not laterally. To
secure the steering wheel, a user inserts the cap 44 into collar 42
and rotates it until the parts are assembled and locked together as
will be described below.
[0039] It will be understood by those of ordinary skill in the art
that the parts of the steering column may be connected by any of
various engagement means--all of which are within the scope of the
invention. For example, column cap 44 may be held within collar 42
by way of a tight frictional engagement, detent mechanism, threaded
engagement or any similar locking mechanism. In addition, the
steering wheel and steering column cap could be permanently mounted
to the inflatable vehicle or made unitary therewith, Still further,
in another embodiment of the invention--a steering column cap is
not required. Rather, a steering wheel could be mounted by a pivot
directly onto a base provided on the vehicle--obviating the need
for a steering column cap.
[0040] Each of the engagement means requires that the securement
between the steering column cap and body be such that it is
sufficiently strong that even an adult excited during the playing
of the WII game can not physically separate the steering wheel from
the body of the inflatable kart.
[0041] FIG. 3B shows a perspective view of the steering column cap
44. As shown, a rotating head 49 couples a steering wheel cradle 50
to the steering wheel column 44. In a preferred embodiment, head 49
extends from a cylindrical shaft (not shown) that is rotatably held
in the interior of steering column cap 44. The cylindrical shaft
serves as an axle for the movement of head 49. Head and attached
cradle 50 are thereby free to rotate as would a real-life steering
wheel. In a preferred embodiment, however, in the interior of the
steering column cap, the cylindrical shaft that supports head 48 is
attached to two springs at two diametrically opposed regions. The
result of the attached springs is that when not acted upon by a
user, the cylinder (and ultimately the attached steering wheel) is
biased to return to a default position.
[0042] Steering wheel cradle 50 comprises a bottom, fixed member 54
and a top movable cover member 56. Bottom member 54 has a floor and
two opposing sidewalk that form a carriage 55. Bottom member 54 and
top cover 56 are preferably joined together--most preferably by way
of a mechanical or live hinge. Steering wheel cradle 50,
selectively attaches the steering wheel 22 to the steering column
cap 44--as described in more detail with reference to FIGS.
3C-3F.
[0043] FIG. 3C a shows steering wheel 22 having a compartment 58
for receiving a game controller 60. The steering wheel 22 is
preferably molded of plastic or such similar material. As shown, a
crossbar 60 (or spoke) spans the diameter of the steering wheel 22.
In a preferred embodiment, crossbar 60 is molded to comprise a
groove that is sized and shaped to conform to the outside contours
of a respective game controller. A user places the controller 60
into the compartment 58, which fits snugly therein. Crossbar 60
functions as part of a compartment for receiving a game controller
and as the attachment point for the steering wheel 22 (as described
in more detail below).
[0044] Referring to FIG. 3D, with the controller 60 placed within
the compartment 58, the steering wheel 22 is ready to be attached
to the steering column cap 44. To that end, a user opens the cover
56 of steering wheel cradle 50 to expose carriage 55. Carriage 55
is sized and shaped to accommodate an underside surface of crossbar
60. Once the steering wheel 22 with a game controller 60 positioned
therein is placed into the carriage 55--top cover 56 is pressed
downward (FIG. 3E) to a closed position (FIG. 3F). In a preferred
embodiment, a slot 57 provided on cover 56 catches a corresponding
elongated tooth 59 on bottom member 54. Slot 57 and tooth 59 engage
to keep maintain cover 56 in a closed position, Cover 56 functions
to secure the steering wheel 22 to the steering column cap 44 and
to secure the game controller 60 within the compartment 58. The
steering wheel 22 is thus easily attachable/detachable from the
vehicle via cradle 50.
[0045] It should be noted that in some embodiments of the invention
a top cover or clasp is not required to maintain the controller
within the compartment. Rather, compartment 58 is sized to capture
and maintain the controller in a tight frictional grip.
Furthermore, steering wheel may be fixed to a pivoting
member--obviating the need for a cradle.
[0046] FIGS. 4A through 4G illustrate and show the interconnection
between collar 42 and steering column cap 44. In fact, collar 42
and steering column cap 44 comprise an interconnectable steering
wheel attachment mechanism allowing the parts which comprise the
inflatable kart to be separated and yet securely assembled when use
is desired.
[0047] While the terms steering column cap 44 and collar 42 are
used to identify the parts, it is understood that a steering column
cap is that portion of the kart between the base 40 and rotating
head 49. A "steering wheel attachment mechanism" is coupling device
for coupling a steering wheel to a vehicle body.
[0048] FIG. 4A shows collar 42 which is attached to base 40 in a
secure manner. A slot or receptacle 48 is provided, the purpose of
which will be described hereinafter. Collar 42 is annular and
encloses therewithin a plastic socket member to which column 44 is
attached. Collar member 42 comprises an inner annular ring 43
having annularly located tabs 130. Additionally, an opening 132 in
the upper portion of the annular wall of collar member 42 is
provided for ease of assembly.
[0049] FIG. 4C is a perspective view of the underside of steering
column cap or cap 44. Column cap 44 is a tubular member which is
adapted to attach to collar 42. Three slotted locks 140 are
attached to an inner annular ring member 144 and are integrally
formed therewith. Each locking member 140 comprises an inner
slightly curved slot 142 which is adapted to receive tabs 130 in
collar 42. As may be seen from FIG. 5, slot 48 receives tab 46 as
will be described hereinafter.
[0050] FIGS. 4D and 4E are respectively bottom and top plan views
of members 44 and 42 showing the interlocking members 130 and
140.
[0051] FIGS. 4F and 4G illustrate how members 130 and 140 interlock
with tabs 130 fitting into the slot area formed in part by slot 142
and the surrounding wall structure thereabout. When receptacles 140
are rotated (in a clockwise manner in the orientation depicted in
FIGS. 4F and 4G) they capture tabs 130 as illustrated in FIG.
4G.
[0052] In one preferred embodiment of the invention, a locking
mechanism is provided to further ensure that these members may not
become separated during active use. For example, tab 46 is moved
downwardly as in FIG. 5 to lock into recess 48 in base 40,
preventing relative rotation between cap 44 and collar 42. The
additional locking mechanism provided by tab 46 in slot 48 further
ensures against separation of the steering wheel column assembly
during active use. As shown in FIG. 4C, a pair of locking teeth 148
disposed in parallel channels attach tab 46 to column cap 44 and
which prevent lateral movement of the same.
[0053] Referring to FIG. 6, in a preferred embodiment of the
invention, cradle 50 is connected to head 48 by way of a pivotable
connection. In that manner, steering wheel 22 is adjustable by
pivoting the same to a desired angle, Pivotable connection may be
achieved by way of a ball and socket or by such similar pivotable
connection between head 49 and cradle 50.
[0054] Referring to FIG. 2, with a game controller positioned and
secured within the steering wheel compartment--a player naturally
controls the steering wheel--much the same way one would in a
real-life car. The enclosed remote accordingly controls a car shown
on a screen in accordance with any of various video driving games.
The car is lightweight and can be easily moved around within signal
range of the game's controller/sensor.
[0055] As may be well understood, the game controller requires line
of sight to the console so that the mounting of the game controller
must be such that even though it is housed within an inflatable
kart, it must be positioned to provide such line of sight
communication. To achieve that end, the steering wheel is
positioned at the peak 25 of front body structure 24 (as shown in
FIG. 1).
[0056] It will be understood that various types of vehicles and
styles of sports vehicles could be produced according to different
embodiments of the invention, For example, referring to FIG. 8, an
inflatable personal watercraft (PWC) 61 is shown for simulating WII
water sports. As shown, the vehicle is designed to mimic the look
and feel of a real JET SKI or WAVE RUNNER. The PWC comprises an
inflatable bottom platform 62, upon which an oblong seat 64 is
disposed. An outward pointing front body 66 serves as a mounting
point for a handle bar column 68. Handle bar 70 is pivotably
connected to fixed column 68 by way of a pivot member or fulcrum as
is well known in the art.
[0057] For some driving games, a WII nun chuck may be required for
playing. To that end, in an embodiment of the invention, handle bar
70 is provided with two different compartments--each designed to
receive respective units of the WII nun chuck. As shown in FIG. 8,
handle bar 70 comprises a right-hand bar 72 and a left-hand bar 74.
The right hand bar 72 comprises a compartment that is sized and
shaped to receive a standard WII remote. As shown, a cut-out or
window 76 is provided in the front-facing side of right-hand bar 72
to allow access to the "B" button of the WII remote. Left-hand bar
74 is sized and shaped to receive the complementary unit to the WII
remote--forming the nun chuck. Left-hand bar 74 is similarly
provided with a window 78 for allowing access to a button that is
positioned on the underside of the nun chuck unit.
[0058] In other embodiments of the invention, a game controller
holding assembly is attached to any of various inflatable vehicles
or vessels, such as, an airplane, ship, submarine, army tank, and
motorcycle in order to respectively simulate operating conditions
of the same.
[0059] It will be understood by those of ordinary skill in the art
that the invention set forth herein relates, broadly, to a novel
inflatable vehicle having a game controller attachment means in a
steering mechanism. The steering mechanism (e.g. steering wheel,
handle bar, yoke, etc.) is either permanently or temporarily
attached to a base on the inflatable vehicle. A base refers to any
specific insertion or mounting point for a steering mechanism. For
example, a base may comprise an area of reinforced material for
receiving a steering wheel or an area having an attachment
mechanism for attaching a steering mechanism.
[0060] It will be further understood that the invention is not
limited to accommodating a WII remote--but encompasses an
inflatable vehicle that similarly receives any game
controller--wired or wireless. For example, a compartment 58 may be
molded to accommodate SONY's MOVE controller or any similar game
controller.
[0061] In one embodiment of the invention, the inventive inflatable
vehicle is provided with different detachable steering wheels--each
to accommodate respective differently sized game controllers. In
another embodiment, a compartment inside a steering wheel is
designed to receive different inserts--each insert being sized and
shaped to respectively accommodate different game controllers.
[0062] Having described this invention with regard to specific
embodiments, it is to be understood that the description is not
meant as a limitation since further modifications and variations
may be apparent or may suggest themselves to those skilled in the
art. It is intended that the present application cover all such
modifications and variation as fall within the scope of the
appended claims.
