(54) A TOY VEHICLE GAME
(71) We, IDEAL TOY CORPORATION of
184-10 Jamaica Avenue, Hollis, N.Y. 11423,
United States of America; a corporation organized and existing under the laws of the state of Delaware formerly of New York,
United States of America, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
The field of the invention is that of a toy vehicle game with remotely controlled electrically driven miniature toy vehicles and more particularly miniature cars that are operated on a closed track way having contact strips through which power is supplied to the vehicle through brushes or collectors carried by the vehicle. The nature of the improvements is described more in detail hereinafter.
Toy vehicle games with remotely controlled miniature vehicles particularly cars are known in the art. Typically a conventional type of remote control vehicle is provided as part of a remote controlled system wherein the vehicles operate on a track having contact strips through which the power is supplied, the vehicles being adapted for remote steering control whereby they are able to pass one another and change from one lane to another.
Certain categories of vehicles are known as "slot cars" and in this particular category of system the vehicles are constrained directionally by virtue of slots or guides to follow a particular pre-determined path.
However, that type of system wherein the vehicle travels on a flat track with flush contact strips and is steerable remotely, whereby it can pass other vehicles and can transfer from one lane to another is more realistic. An exemplary form of this type of system and vehicle is disclosed in patent No.
3,774,340. This system, as known, however, leaves room for improvements. In this type of prior art system, the vehicle is controlled remotely by control of the voltage, that is power supplied to the electric driving motor of the vehicle which drives the rear wheels through a gear train. The motor moves physically relative to the chassis, being actuated by inertia, that is momentum upon change in voltage supplied in response to remote control. The steering means includes steerable front wheels which can be turned in one direction or the other for causing the car to transfer from one lane to the other of two lanes provided in a track way with side walls which can be engaged by a front wheel of the vehicle for positioning the front wheel steering means in a position to be activated by movement of the driving motor for turning the wheels in a manner to cause the vehicle to change lanes.In this category of system, the steering mechanism is relatively complex; it depends upon the steerable front wheel having engagement with the side wall of the track, and it depends upon the physical fore and aft movement of the propelling motor.
Thus, these constructions leave room for improvements in the way of simplified, less complex and more dependably operable mechanisms. The herein invention as described in detail hereinafter seeks to overcome all of the shortcomings of the prior art and otherwise to achieve the purposes of the particular objectives as set forth hereinafter.
According to the present invention there is provided a toy vehicle game including electrically operated miniature vehicles which are remotely controlled, a track for the vehicles having two lanes and lateral walls and the vehicles being steerable to turn from a position adjacent one side wall to a position adjacent an opposite wall; at least one additional vehicle being operated on the track at a lower speed than the maximum speed of the other vehicles, and the other, remotely controlled vehicles are controlled to steer around and pass the one additional vehicle whereby the controlled vehicles are restricted to passing the one additional vehicle one at a time at a random time and location round the track circuit; characterised in that the vehicles have current collectors connected to the vehicle propulsion motors and co-operable with current conductors in the track, the controllable vehicles each have a steering system for controlling the direction of motion of the vehicles and responsive to electrical pulses transmitted through the remote control system to cause vehicles to overtake and pass the additional or drone vehicle operating on the track at relatively constant speed.
The driving motor of each remotely controlled vehicle is mounted to provide for physical movement in response to variation in torque applied to the worm gear of the driving train that drives the rear wheels. The motor of said vehicle may move angularly about an axis above or below it or about its own axis, this movement being imparted to the steering mechanism for turning the front wheels to cause the vehicle -to transfer from one lane to another.
Further improvements reside in the steering mechanism itself. The front axle is mounted to turn about a vertical axis, The steering means carries a vertical steering post which is offset from the center of the axle so that upon its being moved forwardly or rearwardly, the front wheels are turned. A steering stem member is carried by the motor and is movable by the motor to engage the steering post to turn the front wheels one way or another depending upon the position of the steering post at the time of engagement by the steering stem member.In one form of the steerable vehicle of the invention, prepositioning of the steering post is achieved by way of a positioning member which is rotatable relative to the vehicle chassis about a vertical axis, the positioning member carrying rollers engageable with the track side walls and the positioning member being connected to the front axle through a lost motion connection for pre-positioning the steering post to thereby predetermine the direction that the front wheels will be turned upon actuation by movement by the driving motor.
In a simplified form of the steerable vehicle used in the game of the invention as described hereinafter, the front axle has only two positions. It occupies one position or the other for turning and travelling along a lane. Impulses from the drive motor position it in one position or the other.
In one embodiment according to the invention, the steerable vehicle includes means for realizing the steerable impulse in response to a changing current wherein the motor is mounted to move angularly about an axis spaced from the axis of the motor or alternatively moves angularly about its own axis.
In a further embodiment according to the invention the steerable vehicle has a steering mechanism wherein the front axle is turnable about a vertical axis and a vertical steering post is provided which is offset laterally and which is movable fore and aft for turning the front wheels in one direction or the other, the steering post being movable by a steering member that is actuated by movement of the motor itself in response to a variation in torque of the driving motor.
It is proposed that the toy vehicle game achieves proportionally realistic acceleration and deceleration of the vehicle as the speed is changed by the operator and this may be achieved in part by way of the motor having a fly wheel. A corollary is to realize a greater range of speed control and to achieve control by way of current change rather than voltage change. It is further desirable to provide a game wherein controllable cars and noncontrollable traffic vehicles are inter-mixed with the capability of the control cars being able to overtake traffic cars that they can pass or slow down to avoid collisions.
In preferred forms track layouts of the game of the invention, such are oval or figure 8 with simplified means for converting from one to the other. It is further desirable to provide a track which is foldable for easy storage, and instant erection and readiness for operation without the typical assembly requirements.
The invention will be described further, by way of example, with reference to the accompanying drawings in which:

Figure 1 shows schematically an oval track
10 having side walls which corresponds generally to types of track known in the prior art. The track is provided with embedded flush contact strips as designated at 11 and 12, providing a pathway to be followed adjacent one side of the track and numerals 13 and 14 designate another pair of flush contact strips providing another pathway adjacent the other side of the track. The remotely controlled vehicles are able to transfer from one pathway to the other, that is, from one side of the track to the other.
The vehicles as will be described, are provided with pairs of brushes or collectors that engage the flush contact strips whereby power is supplied to the driving motors of the cars.
In the exemplary arrangement shown, circuitry is provided for providing power to two cars having electric driving motors identified as the A and B cars. Power is supplied through a transformer as designated at 20 having a primary winding 21 and a secondary winding 22 and providing appropriate voltage for the circuitry. The circuitry of the individual driving motors of the cars A and B is illustrated within the oval track 10. The A car has a motor winding designated at 26, which receives power through brushes 27 and 28 engagable with the flush contact strips. The car B has motor winding 30 which receives power through the brushes or collectors 31 and 32. In the circuits of the motor windings 26 and 30 are the reversely connected diodes 34 and 36 so that the windings operate on opposite polarities of the applied voltage.
The circuitry of Figure 1 is arranged to apply voltage of one polarity to one car and of the opposite polarity to the other car. The circuitry includes the parallel reversely connected diodes 40 and 42 which are in circuit with potentiometers 44 and 46, which connect to rheostats 48 and 50 to the conductive strips. One of the strips of each pair, that is, 11 and 13 connect to the common wire 52. The control rheostats 48 and 50 connect to the other conductive strips of the two pairs, that is strips 12 and 14.
Numerals 56 and 58 designate switches for the power supplies of the respective cars whereby the current provided can be subtantially varied by closing the switch to shunt a part of the potentiometer and the controlling rheostat to thereby vary the torque provided by the driving motor. As can be seen, half of the AC power wave, that is a half of each polarity is provided to each of the cars so that individual control of each car through its respective controller is possible, whether the car is following one of the pathways of the track or the other.
Figures 2-5 illustrate an exemplary preferred form of a miniature vehicle. The vehicle is schematically shown in these figures. As shown, the vehicle has a chassis which is essentially a flat plate, as designated by the numeral 66, having a shape as shown. It has a narrowed extending front portion 67 as may be seen in Figure 3 and cut outs at the rear part as designated at 68 and 69 at the positions of the rear driving wheels. The electrical driving motor is designated by the numeral 72 and the motor is suspended in a frame having a bottom part 74 resting on the chassis 66 and having end parts 75 and 76 having a shape as may be seen in Figure 5.
Secured to the top of the motor is a rod member 80, the ends of which are journalled in the end members 75 and 76 of the motor supporting frame so that the motor is suspended and can swing angularly about the axis of rod or stem 80.
The brushers or collectors may be conventional, and are not shown.
The vehicle has rear wheels 82 and 83 of suitable type carried on a rear axle 84 journalled in flanges 85 and 86 carried by the frame or chassis 66.
The motor has a drive shaft 90 on which is a worm gear 91 and it meshes with a pinion gear 92 on the rear axle 84. The shaft 90 passes through an opening 94 in the support member 76. The front end of the motor extends into an opening 95 in the support member 75.
As previously explained the motor can swing laterally, that is angularly about the axis of the supporting stem or rod 80. Pinion gear 92 is suitably crowned, that is rounded in cross section to accommodate the angular bodily movement of the motor 72. The operation will be described more in detail presently.
The front wheels of the vehicle are steerable in response to the bodily movement of the motor 72 as will be described. The front steering assembly, is illustrated in the Figures 2-5. The front wheels are mounted on an axle plate member as designated at 100.
This member has upstanding side portions
101 and 102 which carry the axles 103 and 104 of the front wheels 105 and 106. See Figure 5.
Numeral 112 designates a positioning member or yoke which cooperates with the front axle member 100 as will be described. Positioning member 112 has a circular part 113 which overlies the member 100 as shown and it has a forwardly extending neck 114 with a transversely extended part 116. The transversely extending part 116 carries strips at its ends on which are mounted roller wheels
118 and 119, these strips being adjustable inwardly and outwardly to adjustable positions which can be set by way of the screws 120 and 121.The rollers 118 and 119 as will be described more in detail presently, are engagable with the side walls of the track for positioning the part 116.
The positioning member 116 has upstanding from it a vertical steering post 130 which is in a position rearwardly of the axis of the front axle members 103 and 104. The member 100 and the positioning member 116 are pivotally secured together by means of the pivot post 132 as may be seen in Figures
5 with interposed washers 133 and 134.
Washer 133 is in between the positioning member 116 and the member 100 and washer 134 is between the member 100 and the part 67 of the chassis 66. The positioning member 116 is normally biased into a position wherein its transverse part is normal to the chassis by means of the resilient biasing stem
140 which is attached at one end to the part 67 of the chassis and is attached at its other end to a bracket 141 extending downwardly from the positioning member 116.
The axle member 100 and the positioning member 116 are coupled together by way of a lost motion connection which includes a vertical pin 144 upstanding from the axle member 100 through an arcuate slot 146, in the positioning member 116. The exact manner of cooperation of these parts will be described in detail presently.
Attached to the underside of the motor 72 at one side is a forwardly extending dart stem 150, whose free end 151 is pointed at its inner side to define an apex 151a extending inwardly towards the vertical steering post
103. Apex 151a separates two slightly concave cam surfaces 151b and 151c which cooperate with steering post 130 to steer the vehicle's front wheels. As will be described more in detail presently, the motor, of course, applies torque through the worm gear 91 to the pinion gear 92 for driving the rear wheels of the vehicle. There is, of course, a reaction torque applied to the motor 72 such that it can move angularly about the axis of the supporting rod or stem 80.When this happens, the steering stem or dart 150 is moved angularly laterally so as to engage one of its cam surfaces with the vertical steering post 130 to impart steering movement to the front wheels as will be described in detail presently.
Before describing in detail the remote control steering operation of the vehicle, reference will be made to modified forms of motor suspension whereby the same or similar steering operation may be realized. One modified form of motor suspension or support is illustrated in Figure 6 wherein the same reference numerals are used to identify the parts corresponding to the previous embodiment. In Figure 6, the shaft 90 of motor 72 extends through a bearing 160 in support member 76'. At the other end of the motor 72, there is a boss 162 which is journalled in an annular bearing member 163 provided in the support member 75'.
As may be seen the frame of the motor itself is mounted so as to be able to rotate, that is move angularly. Thus, the reaction of the torque applied by the worn gear 90 can cause the body of the motor to rotate angulariy in the opposite direction.
Thus, as may be seen, when the motor rotates about its axis, the dart stem 150 is moved correspondingly and it can engage the vertical steering post 130 to effect steering in the same or similar manner.
Figure 7 is a schematic sectional view showing another form of the invention wherein the motor is mounted for bodily angular movement about an axis spaced below the axis of the motor as distinguished from the mounting illustrated in Figure 5. In Figure 7, the motor 72 is carried on a support plate 170 having brackets such as shown at 171 which are journalled on a stem 172 extending parallel to the chassis and supported by brackets like the one designated at 174. The support plate 170 is engagable at one side with a fixed stop 176 and is engagable at the other side with spring 178. In this form of the invention, the reaction torque as before, can cause the motor to move angularly about the axis 172 and past the dart stem 150 is movable similarly to bring about the steering operation.
From the foregoing, the similarity as well as the differences in the characteristics of the three forms of motor suspension are readily discernible. In each case, the reaction torque is, of course opposite to the direction of the driving torque. With the axis of suspension above the motor, the gear force which is the driving force between the gears acts with and assists the reaction torque in moving the motor for steering. With the motor mounted for angular movement about its own center line, or axis, the gear force produces minimal torque tending to rotate the motor. With the motor mounted about an axis, spaced below the motor axis, the reaction torque and gear force oppose each other.
The operation of the embodiments of
Figures I-5; Figure 6 and Figure 7 is illustrated schematically in Figures 8, 9, 10 and 11. The steering results from bodily movement of the motor in response to changes in torque which move the steering stem or dart 150 with respect to the steering post 130.
That is, when the operator desires to cause their vehicles to change lanes, they operate their respective switch to increase the voltage supplied to their respective vehicles. This increased voltage produces an increase in current supplied to the vehicle's motor. As is characteristic of electric power supplies the current will initially have a high value pulse and then the current level will drop back to a somewhat lower level than that of the pulse.
This pulse of current produces an increase of torque by the motor causing it to pivot momentarily in its mounting. As the pulse of current drops off, the motor returns to its normal position. It is this instantaneous movement of the motor that is used for steering. This steering is essentially the same, irrespective of which of the disclosed types of mounting of the motor is used.
Figures 8-11 are schematic and exaggerated to illustrate the steering sequences.
Figure 8 illustrates the car following a lane of the track adjacent to the side wail W1 at the left. The roller 118 of the positioning member 112 engages the side wall, causing member 112 to rotate clockwise slightly so that pin 144 is moved to the upper end of arcuate slot 145.
The front axle becomes almost perpendicular to the track and the car moves straight ahead.
The left wheel does not engage the side wall of the track. In this position of member 112, steering post 130 is located so that it is opposite the cam surface 151 b of the dart whereby upon engagement therewith the post will be moved rearwardly. This happens upon actuation of one of the control switches shown in Figure 1 to change the current supplied to the motor 72 to produce a current pulse as aforesaid and thus increase the torque delivered by the motor. The car, of course, has inertia and because of its resistance, the driving wheels acting through the gear train will now cause the motor to move angularly about its pivotal mounting. In the case of the first modification, it will swing about the stem 80; in the case of Figure 6, it will rotate about its own axis; and in the case of Figure 7 it will move angularly about the axis of stem 172.Upon the instantaneous increase in torque applied by the motor the cam surface 151b is engaged with the post 130 and pivots member 112 in a clockwise direction, as shown in dotted lines in Figure 8. This causes the axle plate member 100 and the wheels thereon to also pivot clockwise, because of the engagement of pin 144 with the top end of slot 146. Because the axle of wheels 105, 106 is forward of the pivot 132 the wheels have anti-castor effect and, once turned past the dead center direction, will continue to turn in the direction steered. Thus, even though dart 150 returns to its normal position (shown in solid lines) upon reduction of the reduced current pulse, the wheels will continue to turn to the right. Figure 9 illustrates the configuration of the steering wheels after the dart has engaged post 130, initiated turning of member 112 and returned to its original position.As seen therein both the positioning member 112 and the axle member 100 have been turned in a clockwise direction, with pin 146 remaining engaged with the top of slot 146. As a result of this turning of the front wheels, the car changes lanes moving over to the right hand lane of the track as illustrated in Figure 10, and plate 112 is shown in its centered position with respect to the vehicle frame, When the right hand roller 119 of positioning member 112 comes into contact with the right hand side wall Wr of the track the positioning member 112 rotates slightly in a counterclockwise direction relative to the axle member 100 so that plate 146 is moved relative to pin 144 until its opposite or bottom end is adjacent the pin as seen in
Figure 11.The car will now proceed along the right hand lane parallel to the right hand guide wall Wr with the axle of the front wheels being almost perpendicular with respect to the track. In this position steering post 130 on positioning member 112, is now positioned opposite the cam face 151 c on the other side of apex 151a on steering dart 150 so that when the dart moves laterally, in response to an increase in current, cam surface 151 c will engage the steering post and move it forwardly causing plate 112 to pivot counterclockwise.
This will happen when a remote control switch is actuated to increase the current supply and correspondingly the torque of the motor again causing the motor itself to be moved angularly as described. This is illustrated in phantom lines in Figure 11, showing the steering dart in a position with surface 151 c engaging the steering post 130 to rotate positioning member 112 and, because of the engagement of pin 144 with the bottom of slot 146, axle member 100 in a counterclockwise direction, thus turning the wheels for causing the car to move over to the opposite lane again. Again, because of the anti-castor effect of the wheel axle location, the wheels, once turned past dead center will continue to turn to the left, even when dart 150 returns to its normal position because of the drop off of the reduced current pulse.When the cars change lane , they move in response to their own momentum decelerating and then accelerating when the power is again applied.
In addition, a return spring will be used to aid in returning the motor to its normal position, moving steering dart 150 away from the steering post 130.
From the foregoing it will be observed that simply by operation of the switches 56 and 58 for cars A and B that they may be caused to transfer from one lane to the other at will, and may pass ahead or behind of other cars that may be provided on the track way if desired.
Figures 12-15 show a modified form of the invention wherein the axle member 100' is made integral with the transverse member 116 carrying the rollers 118 and 119, the transverse member 116 being connected to the main part of axle member 100' by the neck 114. The member 112' formed as a disc, is separate from the part 116. It has a notch 190 in its periphery cooperating with a post 191 upstanding from the front part 67, of the chassis to serve to limit angular movement of the part 112'. A lost motion connection is provided between the parts 100' and 112' comprising the stem 144 standing from the axle member 100', engaging in arcuate slot 146 in member 112'.
The steering post 130 is carried by the disc member 112 adjacent to the point 151 of steering dart 150. The parts are carried on the stem or arbor 132 overlying each other with the interposed washers 133 and 134, as in the previous embodiment.
The operation of the present embodiment is illustrated in Figures 12, 14 and 15. In the operation, for example, when the roller 118 engages the side wall at the left side of the track, Figure 12 the axle member 100' is moved clockwise into a position with the front axle normally perpendicular to the track so that the car runs along in a straight line parallel to the left guide wall. At this time, the steering post 130 is in a position relative to the point 151 of the dart 150 so that upon the next movement of the dart, the steering post 130 is moved in a direction to rotate the member 112' clockwise and it moves the member 100' with it to turn the front wheels for a turn to the right Figure 14 towards the other side of the track.Figure 14 illustrates such a turn to the right having just been made from the left guide wall and the pin 191 being at the end of the arcuate cut-out 190, as shown.
When the car reaches the other side of the track the roller 119 now engages the right hand side wall, Figure 15 rotating the axle member 100' in a counterclockwise direction bringing the front axle into an almost perpendicular position relative to the track and the car runs along in a straight line parallel to the right hand side wall. The pin 144 has now been moved to the left end of the arcuate slot 146. The steering post 130 is now in a position relative to the point 151 of dart 150 so that when the dart is now moved, the steering post 130 is moved forwardly so as to turn the member 112' in a counterclockwise direction, the axle member 100' turning with it so that a left turn is now made and a car proceeds to the other side of the track until the next turning impulse is imparted from the motor 72.
Figures 16a, 16b and 16c show a modified and simplified form of the invention which does not employ any prepositioning means for the front axle member. In the previous embodiments, normally, while the car is running along adjacent to a side wall the front axle is turned about 5 from normal towards the side wall. The angle of turn of the front axle for turning from one lane to another is normally about 15". For purposes of the present embodiment, it has been found that the car can be operated with the front axle turned at an angle of about 7" from normal towards the side wall with the car running along the side wall.Then, by turning the front axle to a position about 7" from normal in the opposite direction, the car is caused to transfer to the opposite lane and run along the opposite side wall.
In Figures 16a, 16b, and 16c the motor is designated at 72 and the dart at 150 as in the previous embodiments. The chassis of the car is designated at 200. The car has a front part designated at 202 which carries collector strips or brushes, one of which is shown at 204.
The front axle member is designated at 206 carrying steering post 130 operating about a pivot member 207 and carrying wheels 208 and 210. The steering mechanism includes a disc 212 rotatable about a pivot member 213 and having spaced axial pins 214 and 215, the dart 150 actuatable by the motor being in a position between them as shown. Thus, as may be seen, when the motor is pulsed, the dart 150 will move the disc 212 in angular increments clockwise and then counterclockwise
The disc 212 carries a pawi 219 which cooperates with the ratchet disc 220 also mounted to rotate about the arbor or pivot 213. Formed in the disc 220 is a slot 224 having a configuration as illustrated in Figure 16c. The steering post 130 fits into the slot 224. As shown, the slot 224 has three lobes although it may have more.Each lobe has two leg parts parallel to radii connected by a curved loop part. As may be seen, incremental angular movement of disc 212 by means of pawl 220 cooperating with the ratchet teeth in disc 220 will move it in angular steps. During each step, the steering post 130 will traverse 1/2 of one of the lobes of the slot 224. That is, successive steps of the disc 220 will impart reciprocatory movement to the steering post 130. It is positioned on the front axle member 206 to move it angularly to positions about 7" from normal, that is, from perpendicular to the chassis for executing turns from one lane to another as described in the foregoing. The car sequences from a lane at one side to a lane at the other side whenever a turn is imparted to the axle 206 as described.As may be seen, in this embodiment, the car operates without the use of the prepositioning member as previously described.
An additional miniature car or drone vehicle is provided on the trackway in addition to those already described, the additional car being identified as a "jam car". It may be of similar construction but constructed, however, to operate at a substantially lower speed. This car may, for example, be battery operated or may be supplied with current directly from the contact strips, in any convenient manner, but it is not remotely steered and ordinarily operates continuously adjacent one side or the other of the trackway due to centrifugal force or fixed canting of the front wheel. This car serves certain distinct purposes in the system. The remotely controlled cars operating at higher speed will catch up to the jam car which then requires that the remotely controlled can be steered around the jam car. The effect of steering around it prevents the remotely controlled cars from being operated continuously at top speed.
In typical remotely controlled systems including slot car systems, if the cars do not leave the track, there is no race. In the system being described, the jam car makes a race out of the system because it runs slower than the remotely controlled cars and it thereby provides a moving obstacle and maintains only one place where one of the two remotely controlled cars can pass. Therefore, on each lap of the race, there is competition between the race cars to see which one will pass the jam car and yet avoid crashing into the jam car. Thus, as may be seen, this concept provides an active and
exciting race element operable during each lap
in addition to the total race but still there is
no need for any car to become disengaged or disconnected from the control system.
From the foregoing, those skilled in the art will readily understand the nature of the construction of the car, the steering mechanism, and the manner in which the remote control is effected by varying the torque applied by the motor. It is to be observed that various different modes of suspension of the motor are possible, the steering being similar in each case. The steering mechanism involving the front axle member and the positioning member which resets the steering post relative to the steering dart may take different forms as illustrated in Figures 2 and 3 and in Figures 12-15.
