Description
BACKGROUND OF THE INVENTION
This invention relates to toys, and more particularly to a novel
toy vehicle.
BRIEF DESCRIPTION OF THE PRIOR ART
Many forms of driven toy vehicles have been developed, and
generally speaking, they are popular in that the user may easily
associate himself as the guiding source for the vehicle. Some
vehicles have so-called "trick" characteristics, while other seem
to be realistic duplicates of original automobiles or trucks.
Children are particularly fascinated with toy vehicles which are
capable of performing in a manner beyond the capabilities of
conventional vehicles. Accordingly, it is the object of this
invention to meet the continuing need and desire in the art, for
the provision of an improved toy vehicle of this type.
SUMMARY OF THE INVENTION
This invention is directed, in brief, to the provision of an
improved toy vehicle capable of performing in an unconventional
manner.
The best mode currently contemplated for carrying out the invention
includes the provision of a vehicle body with power and motor
components therein, preferably held in a liquid impervious chamber,
and a power train associated with the motor. The body supports
front and rear, hollow, substantially spherical wheels, which are
driven by the power train. Preferably, the motor and power
compartments are at, and below, the axis of rotation of the wheels
to give the vehicle a low center of gravity. Also, preferably, no
part of the body projects beyond the perimeter of the wheels,
thereby facilitating the self-righting characteristics of the
vehicle.

While this invention is susceptible of embodiment in many different
forms, there is shown in the drawings and will herein be described
in detail a specific embodiment therefor, with the understanding
that the present disclosure is to be considered as an
exemplification of the principles of the invention and is not
intended to limit the invention to the embodiment illustrated.
BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT
The toy vehicle 10 of this invention includes a body, generally
designated 12, and forward wheel 14 and rear wheel 16, each of
which are substantially identical. The body 12 includes an outer
decorative shell, and inner supporting webs for supporting
functional components. The decor on the body 12 may include a
simulated exhaust stack 18 and driver compartment 20.
Each wheel 14 and 16 is basically a hollow sphere formed in three
parts, such as the end cap portions 14a, 14b; and 16a and 16b; and
the hollow enclosed central spherical segmental portions 14c and
16c, respectively. An axle 22 and 24 is provided for each of the
front and rear wheels, respectively, and the axle joins the three
portions of the wheels together as a unit, but slightly spaced
apart. The axles are rotatably received in an axle-receiving
opening 26 in each of the axle supporting extensions 28, 30, 32 and
34 of the body 12 to rotatably connect the wheels with respect to
the body 12.
The interior of the body 12 is provided with an intermediate panel
40 which extends thereacross, for supporting some of the components
of the vehicle. Webs or walls 42 and 44 depend from the panel 40
and are provided with outwardly facing notches 42a and 44a for
receiving inwardly facing flanges 46a and 46b of a bottom closure
panel 46. Walls 42 and 44 and panel 46, together with the remainder
of the body shell 12 define a battery receiving compartment 48 for
receiving batteries 50 to be utilized as a source of power for the
vehicle. It is intended that the closure panel 46 and its
connection with the walls 42 and 44 would be such as to form a
liquid-tight seal, so that water or the like would not enter into
compartment 48. The battery compartment 48 includes the usual
spring 52a and opposite contacts 52b, between which the batteries
50 are to be interposed.
Also, depending from panel 40 are a pair of side walls 54a and 54b
and end walls 56, enclosed by bottom 58, to define a sealed motor
chamber 60. Motor 62 is held within chamber 60 and has the usual
rotatably driven output shaft 68 and motor shaft gear 70 thereon.
Motor shaft gear 70 is in meshing engagement with gear 72, mounted
on shaft 74, which is rotatably journalled between upright webs 76
and 78 associated with the body panel 40. Shaft 74 also supports a
reduced gear 80 which is in meshing engagement with a rear wheel
drive gear 82, connected to a shaft 84 which is rotatably mounted
between an upright 86 connected to panel 40 and the aforementioned
upright 76.
Gear 82 includes a hub extension 88 having a recess 90 therein for
receiving a drive belt or band 92. Belt 92 is also received in a
recess 94 of hub 96 associated with front wheel drive gear 98,
connected with shaft 100 which is rotatably journalled between
upright 102 and 104 connected to the panel 40. Each of the front
and rear wheels 14 and 16 has an annular recessed gear surface 106
and 108 respectively, generally medially positioned in the portions
14c and 16c with which the gears 98 and 82, respectively, are in
meshing engagement. By this arrangement, both of the front and rear
wheels are driven responsive to actuation of the motor 62 through
the aforedescribed gear and belt train. It is contemplated that
ribs or fins 110 and 112 would be formed on the wheels 14 and 16
for providing a source of traction of the vehicle on solid
surfaces, such as floors or dirt or the like, as well as, surfaces
for driving the vehicle through liquid mediums, such as water or
the like.
The toy vehicle is provided with a switch means 116 for activating
the motor. Switch means 116 includes the lead wires 118 and 120 and
a switch member 122 which is pivoted to post 124 between walls 44
and 54a. Switch 122 has switch arms 126 and 128 and switch leg 130.
When arm 128 is depressed, the leg 130 will be brought into contact
with the contacts 52b to close the circuit and thereby supply power
to the motor to activate the same to drive the vehicle.
In operation, the vehicle may be placed on a relatively solid
surface, or in water, and the motor activated to drive the vehicle
across or through the medium. In the case of a liquid medium, such
as water, the hollow middle portions 14c and 16c of each wheel
gives sufficient buoyancy to the vehicle to permit the same to
float, and the ribs on the wheels will displace water as the wheels
are driven to propell the vehicle through the water. In the case of
traversal over a relatively solid surface, the ribs give sufficient
traction to propell the wheels across the surface. The low center
of gravity afforded by the low mounting of the battery and motor
relative to the axis of rotation of the wheels tends to cause the
vehicle to "right" itself when the vehicle is either placed on its
side, or after striking an abutment which causes it to fall from
the upright position. The fact that no portion of the body of the
vehicle protrudes beyond the periphery of the wheels, assists in
facilitating this "self-righting" characteristic. It has been found
that even when the vehicle is upside down, eventually the vehicle
will have a tendancy to turn itself right side up, due to both the
wheel configuration and the location of the relative center of
gravity. If the vehicle is directed towards a generally upright
intersecting surface it will merely traverse across the
intersecting surface following engagement therewith, rather than
being stopped in its path of travel. Thus, it can be seen that the
toy vehicle of this invention is capable of providing an extreme
amount of fascination to children who may utilize it to play in
different mediums, such as ground or floors or in water, as well as
causing it to engage obstacles which the vehicle may encounter in
its path of travel.
The vehicle is capable of traversing several different types of
terrain, such as sand, gravel, solid surfaces and so forth in
addition to its ability to propel itself through water with the aid
of the ribs 110. When engaging a vertical intersecting surface, the
combination of the ribs and spherical wheels cause the vehicle to
turn away from frontal engagement with the surface and travel along
the surface or away therefrom. When engaging a corner formed by
intersecting vertical surfaces, the vehicle also is able to work
itself away from the confines of the corner and move away therefrom
or along one of the surfaces as the spherical ribbed wheels
gradually work the vehicle away from such confinement.
The foregoing detailed description has been given for clearness of
understanding only, and no unnecessary limitations should be
understood therefrom, as some modifications may be obvious to those
skilled in the art.
