AERIAL BALANCING TOY
Abstract
A toy body having a driving wheel and an idler wheel in tandem
travels reversibly on an aerial cable. A weighted balancing yoke is
suspended from the driving wheel axle and a reversible electric
motor on the body is connected to the driving wheel. The body is
rockable within limits on the driving wheel axle by reactive torque
so that both wheels engage the cable when the toy travels in one
direction, but the toy body is raised and the idler wheel lifted
off the cable when the toy travels in the opposite direction. The
motor is in circuit with a reversing switch which is engageable
with travel limiting detents on the cable.

Description
This invention relates to new and useful improvements in balancing
toys, and in particular the invention concerns itself with a
balancing figure toy which travels reversibly on an aerial cable or
tightrope.
The principal object of the invention is to provide a highly
amusing figure toy which can provide much entertainment and attract
considerable attention by its unique performance in riding in a
balancing manner on an aerial cable alternately in opposite
directions, the toy having two wheels in tandem and riding on both
wheels in one direction, but raising itself to lift the front wheel
off the cable in a "wheelie" fashion when traveling in the opposite
direction.
The toy is electrically driven and electrically controlled as to be
self-reversing, and inasmuch as for most part its actuating
components are concealed from view, the unique performance of the
toy gives the impression of being caused by mystic forces.
The toy may be utilized for ordinary amusement purposes and the
like, but is also well suited for use as an animated display, such
as in a store window for example, where its positioning on an
aerial cable occupies elevated space which otherwise may not be
used and where the unique performance of the toy on the cable
serves to attract attention to the toy as well as to items of
merchandise which may be displayed beneath it.
With the foregoing more important object and features in view and
such other objects and features which may become apparent as this
specification proceeds, the invention will be understood from the
following description taken in conjunction with the accompanying
drawings, wherein like characters of reference are used to
designate like parts, and wherein:
FIG. 1 is a perspective view of the aerial balancing toy of the
invention;
FIG. 2 is an enlarged side elevational view showing the basic
components of the toy as related to the concept of its manner of
operation;
FIG. 3 is a diagrammatical illustration showing the action of the
toy in traveling rearwardly;
FIG. 4 is a diagrammatic illustration showing the action in
traveling forwardly;
FIG. 5 is a fragmentary perspective view of a portion of the toy in
which the arms of the balancing yoke are removable; and
FIG. 6 is a diagrammatic illustration of the action of the toy, its
forward travel being shown by full lines and its rearward travel by
dotted lines.
Referring now to the accompanying drawings in detail, FIG. 1 shows
one embodiment of an aerial balancing toy in accordance with the
invention. In this particular instance the toy designated generally
as 10 is a figure toy simulating a clown riding a bicycle on an
aerial cable or tightrope 11 stretched between a pair of suitable
supports 12. However, it will be understood that this particular
figure simulation is by no means critical and that various other
figure simulations may be utilized.
Thus, for purposes of explanation of the basic concept of the
invention reference is drawn to FIG. 2 which shows a peripherically
grooved wheel 13 adapted for rolling on the aerial cable 11 and
having an axle 14 at its axis of rotation. The axle 14 carries a
suitable mounting 15 from which is suspended a balancing yoke 16,
the yoke extending laterally from both sides of the wheel and
downwardly below the cable 11 where the lower ends of the yoke are
provided with weights 17 so as to maintain the wheel 13 in a
balanced condition on the cable.
A support member 18 is rockably mounted on the axle 14 and extends
generally upwardly therefrom. A reversible electric motor 19 is
supported by the member 18 and is drivingly connected to the
peripheral portion of the wheel 13, as by suitable gearing 20. The
support member 18 carrying the motor 19 is swingable or rockable
about the wheel axle 14 in opposite directions as indicated by the
arrow 21, the extent of its rocking being limited by fixed stops
22, 23 which are provided on the axle mounting 15, forwardly and
rearwardly of the axis of wheel rotation. The member 18 may be
shaped so as to engage the stops 22, 23 directly, or a pin 24 may
project laterally from the member 18 to engage the stops. Also
fixed to the axle mounting 15 is an arm 25 which extends downwardly
and has secured to its lower end a reversing switch 26 disposed in
close proximity to the cable 11. The switch 26 and the motor 19 are
in circuit with a source of current, such as dry batteries
hereinafter described.
It will be understood from the foregoing that the yoke 16, the
switch-equipped arm 25 and the stops 22, 23 are fixedly associated
with the axle mounting 15, while the wheel 13 driven by the motor
19 is free to rotate, and also while the motor-carrying support
member 18 is free to rock about the axle 14 within limits set by
the fixed stops 22, 23.
With this in mind, attention is directed to FIGS. 3 and 4 from
which it will be apparent that when the motor 19 is energized so as
to drive the wheel 13 in the direction of the arrow 27, the
reactive torque through the gearing 20 between the wheel and the
motor will cause the motor-carrying member 18 to rock or swing
about the axle 14 in the opposite direction as represented by the
arrow 28, that is, in the direction of the stop 22 as shown in FIG.
3. On the other hand, when as shown in FIG. 4 the motor 19 is
energized to drive the wheel 13 in the direction of the arrow 29,
the reactive torque will swing the motor-carrying member 18 about
the axle 14 in the direction of the arrow 30 and against the stop
23. This alternate rocking of the motor-carrying member is
effectively utilized to obtain a unique performance of the toy on
the aerial cable, as will be presently explained.
In FIG. 1 the figure toy simulation is that of a rider on a bicycle
and this includes a vehicle frame 31 of which the aforementioned
member 18 is a component. The driving wheel 13 is the rear wheel of
the simulated bicycle and the driving motor 19 is conveniently
concealed in the body of the simulated rider 32. The body of the
rider may also accommodate dry batteries for energizing the motor,
although it is preferred that such batteries be housed within
containers at the lower ends of the balancing yoke 16, as indicated
at 33 in FIG. 1, so that the batteries themselves may serve as
weights for the yoke, in place of the weights 17. In any event, the
bicycle frame 31 is also provided with a peripherally grooved front
wheel 34 which may be regarded as an idler wheel in the sense that
it is not driven like the driving wheel 13. Unlike in an actual
bicycle, the front wheel 34 is not steerable, and is arranged in
tandem with the back wheel 13 so that during a certain stage of
operation of the toy, both wheels may ride along the cable. It will
be understood that the front wheel 34, not shown in FIGS. 3 and 4,
is disposed forwardly or to the left of the driving wheel 13, as
viewed in these FIGS. wherein the forward direction of travel of
the toy is indicated by the arrow 35 and the rearward direction of
travel is indicated by the arrow 36. It will be also understood
that the vehicle frame 31, the front wheel 34, the motor 19 and the
rider 32 are all fixedly connected to the frame member 18 and are
swingable therewith, as at 28 or 29, about axle 14, between the
limits provided by the stops 22, 23.
Reference is now drawn to FIG. 1, FIG. 4 and to the solid line
showing in the diagrammatic illustration of FIG. 6 in which the toy
travels in the forward direction of the arrow 35. Under these
conditions, as already explained in regard to FIG. 4, the reaction
torque of the motor 19 driving the wheel 13 in the direction of the
arrow 29 will pivot the support member 18 upwardly and rearwardly
as at 30, thus causing the entire vehicle frame 31 to be swung
upwardly about the axle 14 and the front wheel 34 to be raised off
the cable 11, until the member 18 comes into engagement with the
stop 23. At that point the driving wheel 13 will propel the toy
along the cable forwardly in the direction of the arrow 35, but the
reaction torque will still maintain the vehicle frame in its raised
position, with the front wheel 34 off the cable.
Any suitable type of a travel-limiting detent 37 is positioned on
the cable 11 at the forward limit of travel of the toy, and when
this detent becomes engaged by the switch 26, the switch is
automatically actuated to reverse the direction of rotation of the
motor 19. As this occurs, the forward travel of the toy is
immediately arrested and during a short subsequent period the
reversed rotation of the motor produces a reactive torque which
causes the member 18 to swing about the axle 14 in the direction of
the arrow 28 (see FIG. 3), that is, in the direction of the stop
22. This results in lowering of the entire vehicle body 31 so that
the front wheel 34 comes into engagement with the cable 11,
whereupon the driving wheel 13 will propel the toy rearwardly in
the direction of the arrow 36 while both the wheels 13, 34 run
along the cable 11, as indicated by the dotted line showing in FIG.
6.
A second travel limiting stop 38 is placed on the cable 11 at the
rear end of the vehicle travel and when the switch 26 comes into
engagement with the stop 38, it is actuated to again reverse the
direction of rotation of the motor 19 so that the vehicle frame is
again raised to lift the front wheel 34 off the cable and forward
travel of the toy is repeated, with only the rear driving wheel 13
in contact with the cable.
It is possible that during forward movement of the toy, the rear
driving wheel 13 may not engage the cable 11 with such precision as
to assure engagement of the front wheel 34 with the cable when the
toy body is lowered at the forward end of its travel. In such an
event the front wheel will miss the cable and drop to some extent
on one side of the cable or the other, but by that time the support
member 18 will come in contact with the forward stop 22 and further
dropping of the front end of the vehicle will thereby be prevented
so that even under such unlikely conditions, the toy will remain in
position on the cable.
Suitable electrical conductors (not shown) are of course suitably
arranged to connect the switch 26 and the motor 19 in series to the
batteries 33 which, as already indicated, may be housed in
containers at the lower ends of the balancing yoke 16.
In order to provide the required low center of gravity for the toy,
the balancing yoke 16 must extend considerably below and also to
both sides of the toy body, and if the yoke were permanently
attached to the mounting 15 on the axle 14 of the driving wheel 13,
some problems may be encountered in compact packaging of the toy
for purposes of shipment or storage. Thus, FIG. 5 shows an
arrangement whereby such problems may be avoided in that the yoke
is made in two separate pieces 16a, only one of which is shown, the
yoke piece 16a being provided at its upper end with a pronged plug
39 which is separably connectable to a socket 40 in the mounting
15, thus permitting the yoke piece to be removed when the toy is
not in use.
The prongs of the plug 39 may be electrically insulated from each
other and in circuit with different poles of the batteries at the
ends of the yoke, and appropriate electrical connections may be
made from the socket 40 to the switch 26 and motor 19 so that the
electrical circuit through the pug and socket 39, 40 is
automatically interrupted when the yoke members 16a are separated
from the toy body is automatically reestablished when the yoke
members are installed in their position. If the yoke members 16a,
the switch arm 25 and the motor supporting member 18 are formed
from metal, they may in themselves be used as the ground portion of
the electrical circuit and may be hollow to accommodate wires of
the rest of the circuit, thus making the use of double conductors
unnecessary.
