ABSTRACT OF THE DISCLOSURE
A toy vehicle and toy vehicle game are disclosed in which a plurality of toy vehicles are provided that collect current from conductor strips in a slotless track and switch lanes when the current polarity is reversed. A toy drone car is used in the game which collects current from the strips associated with the other cars and it includes an electrical circuit which insures that current of only a predetermined desired polarity is supplied to the motor in the vehicle to propel the vehicle in a forward direction around the track.
As a result the vehicle is driven about the track in a forward direction regardless of the polarity of current applied to the collector strips.

In one proposal a battery powered toy vehicle is disclosed for use as a drone car moving at constant speed on the track of a toy vehicle game in which other controllable vehicles were provided. The controllable vehi.cle's speed could be varied and their relative lane positions on the track could be changed by changing the polarity of the current supplied to those vehicles to enable them to pass each other and/or the drone car. In that case the drone car was driven at a relativély constant speed and its battery was continu-ously trickle charged ~rom the track conductor strips as it moved along the track.

A to~ vehicle ~ame is pxo~ided in one embodiment in which. a motor driven drone vehicle is adapted to receive current from the cuxrent suppl~ tracks of two contxollable toy vehicles and is dxiven thexeby at a speed proportinal to the hi.ghest voltage of proper polarity which it receives~
The described toy vehicle race game includes a drone car or obstacle vehicle that is automatically operated at a speed proportional to at least one of the othex vehicles in the game when such other vehicle is operated. The des-cribed toy vehicle and toy vehicle game is relatively simple and inexpensive in construction~ It is also durable and relia~le in use.
In accordance with an aspect of the present invention a toy vehicle is provided whlch is adapted to be used in a toy vehicle race game of the type havi.ng a track and a .. plurality of current supply strips in the track along the path of travel for the toy vehicles thereon. One such toy vehicle game is disclosed in U.S. Patent Number 4,078,799.
In that t:ype of game the track pro~ides at least two lanes for toy vehicles, with power being supplied to the respective toy vehicles under the independent and separate control o~ the players so that each vehicle's speed of movement and its position alon~ the track (i.e. its relative position in the respective lanes) can be independently controlled by the operators regardless of the lanes in which the ~ehicles are located. The toy vehicle of the described embodiment is used on this track to provide, accordi.ng to one feature o~ the invention, a drone car for the game which provides an obs.acle on the track, requiring the players to operate their con-trol.lable vehicles to steer around and pass the drone.
z The d~one includes a f~me having an electric motor ~ounted there~n for d~i~in~ at least one drive wheel of the vehicle. Electrical current from the t~ack is collected througll current collectors which are operatively connected to the motor through a diode ~ridge circuit which supplies only cuxrent of the desired polarit~ to the motor so that the drone is always driven about the track in the foxward direction. Preferabiy the vehicle includes a step,down transmission ratio so that it will move at a slower speed than the fastest moving controllable vehicle on the tracX.
An embodiment of the present invention will now be described, by way of exa~ple, with reference to the accomp-an~ing drawings in which:-Figure 1 is a plan view of a toy game within ~hich the toy vehicle is utilized;
Figure 2 is a longitudinal sectional view of the toy , vehicle constructed in accordance with the present embodimenti Figure 3 is a plan view, with the body removed, of the toy vehicle illustrated in Figure 2;

Re~erring now to the drawings in detail, and init~
ially to Figure 1 the~eo~, it will ~e seen that a game 10 i~ which the t,oy ~ehicle is adapted - to be utilized includes a track 12 defining two lanes 14, 16 along which operator controlled toy vehicles 18, 20 are adapted to move and pass each other, In accordance with this e~odiment a drone car 22 is placed on the track to move along the track at a speed which is slower than that of the speed of at least one of the controllable car~ thereby presenting an obsta le to the vehicles 18, 20 which must be passed as the vehicles move around the track. - ~~
The game 10 is descri~ed in detail in the abov~ U.S.
Patent Number 4,078,799 whieh inelu~es ~ detailed deseription of the operation and strueture thereof. sasieally the gams ineludes three eonduetive strips A, B, C embedded in eaeh lane 14, 16 substantially flush with the traek surfaee, with eorres-ponding strips in eaeh lane (i.e. strips A, strips B and s~rips C) being eleetrieally eonneeted to eaeh other, and with stcips C
being eonneeted to eleetrieal ground, as shown in Figure 5. Strips A and B are respectively controlled by individual controllers 24, 26 operated by the players to control current supply thereto and to also control the polarity of current supp~ied to the toy vehicles. The latter are provided with curre~Lt collectors on their lower sur~aces respectiYely associated with the strips A or B so that, for example, vehicle 1~ collects current only from the strips A undèr the control of controller 24 and vehicle 20 collects current only from the stri~s k. The dri~e arrange~ent of the vehicles 1~, 20 is such that one or the ot'ner o~ their rear drive ~heels is driven in accordance with the polarity of the current supplied to its associated corltact stri~ so that the toy vehicle is driven against eithcr ., , ., '.~

This will enabl'e the operators to turn their vehicles 1~, 20 out of a lane to pass drone car 22 or to pass each other.
~he'control system 30 for the toy vehicle game ~s sho~m schematically in Figure 5 and includes, in addition to the respective controllers 24, a plug 32 by which the system can be connected to an electrical AC power source and a trans-former 34. Power is su?plied from transformer 34 through a half-wave recti~ier 36 including two diodes connected as sho~n to separately supply current to the controllers 24, 26. ~ach 'controller is provided as a hand held unit and incl.udes a ' variable resistor 38, operated as a trigger on the unit, as we'Ll as a single pole double throw switc'l 40. Current fro~
controller 24 is supplied through its variable resistor 38 to the contact strips A and current from the controller 26 is supplied through its variable resistor to the contact strips B. The variable resistors may be of any convenient construc-tion to permit the operators to vary the current supplied to their respective contact strips, and thus their respective vehicles, in order to vary the speed of the vehicles.
The polarity of the current supplied to the toy vehicles is separately and independently controlled by switches 40 so that the polarity of current supplied to the motors of the respdctive vehicles, as controlled by ~he respective con-trollers, will vary in accordance with the position in which the switches l~0 are placed. By this arrangement each player, , using his controller 26 or 24, can control the speed ~f his vehicle along the track 12 and he can also variably position his vehicle along the track si~ply by changing the polarity of current supplied to the vehicle. As described above the polarity of the current supplied to the motor of the respec-tive toy vehicles will determine which of the two rear dri.ve wheels is powered, and this will determine which lane the vehicle will be driven in. In this embodiment of the inven-tion, the motors in the toy vehicles 18, 20 and the current supply circuit of Figure S are arranged such that the left drive wheel of the vehicleswill be driven when posltive polar-ity current is supplied thereto and thei,r,right drive wheels will be driven when negative polarity current is supplied thereto. For example, lowermost diode 36 is adapted to conduct during Positive half-cycle~ of the alternatitlg current and uppermost diode 36 is adapted to conduct during negative half-cycles of the alternating current. I~hen a switch 40 of one of the controllers engages a left-hand contact, posit~ve current 10ws from transformer 34, lowermost dio'de 3~, switch 40 and variable resistor 38 to a corresponding track (A or B), and thence through the motor o the respec~ive vehicle to track C. If the switch 40 engages a right-hand contact, then negative current flows from transformer 34, upper~.ost diode 36, switch 40 and variable'resistor 38 to the corresponding track (A or B), and thence through thé motor of the respective vehicle to track C.
~s illustrated in Figure 1, when it is desirecl to switch a vehicle from the ou~er lanc to t!,e innel^ lane, as shown with vehicle 20, the polarity of current supplied to the vehicle is selected to drive the outer or right ~heel of .. . . .

the vehicle thereby moving the vehicle leftwardly into ~he inner lane. Likewise, when it is desired to move the vehicle outwardly the inner or left wheel of the vehicle is driven, by properly selecting the polarity of current supplied to the motor of the vehicle, so that the vehicle will move ~oward the right and into the outer lane. Thus the operators have complete control over both the speed of the vehicle and the lane in which the vehicle will move.

~ 2 play value of the game as all players will have to pass the drone car during tne game at some stage of operation of the game, and this introduces a further variable factor into the game requiring an additional degree of skill and vehicle S control in order to win the "race".
Drone car 22 includes a frame 42, plastic body 43, and a pair o~ front and rear drive wheels 44, 45 respecti~ely.
The front wheels are preferably mounted in a slight angular relation to the longitudinal axis of the body so that the 1~ vehicle will always be driven toward and against one of the side walls of tlne track. Thus, as illustrated in Figures 3 and 4, the frame 42 has front ~heel mounts 46 which are formed ,at angles to the longitudinal axis of frame 42, with ~heels 44 being rotatably mounted thereon, so that wheels 44 are canted slightl~J to the right so the vehicle will stay in the outer lane of the track. If the front wheels are instead canted to the left the vehicle will stay in the inner lane of the trac~.
Alternately the front wheels can be aligned straight on the frarne. In that case, because of the e~fects ol centrifugal force the drone car will normally move in the outer lane against outer wall 30, even if it is initially placed in the inner lane 16, because as the vehicle passes around a turn in the track it will be thrown by centxifu~al force into the outer lane against outer wall ~0.
The rear drive ~heels 45 àre fixed on a rear drive shaft 47 which has a centrally located spur gear 4~ rigidly secured thereto. This spur gear is driven through a worm gear 49 mounted on the output shaft 50 of an electric motor 52 molmted on rarne 42. Current is supplied to the motor 52 from the contact strips on the track through a current control .. . _ ' , ' _ , . . ..
:~ ~
circuit 53 (Figure 6), ~Jhich includes a diode bridge 54, and a plurality of collector strips 55, 56, 57 mounted on the lower surface of frame 42 of the vehicle. These collector strips are or~ed of flexible metallic material and are removably mounted on the bottom of the frame 42 in any convenient manner. The collector strip 57 is located to contact strips C, i.e. the strips of the track connected to the ground, while contact strips 55, 56 are positioned to contact strips A and B, respectively and continuously pick up current from the track.
Collectors 55, 56 are electrically co~nected to the diode bridge 54 to supply current to the bridge. Since i~ is necessary to supply current to the motor 52 of only the polar-ity which will drive vehicle 22 in the forward direction, the diodes 58 o~ bridge 54 are arranged to pe~mit current flow to -1~ ~ly ~r,^ 3~ c~ ct^~ ~ Th~ls th~ rr~ to~s r~,n c~l lert ~urrent from each o~ the strips A, B and C to supply current of prc~er polarity to motor 52. That is, if the polarity of the current applied to collectors 55 and 56 both are positive, then such positive current appears~s~current positive half-cycles. .
Hence, positive current flows from col.lector 55, through. diode 58a, lead 60, motor 52 and diode 64 to collector 57. Also, positive current flows from collector 56, through diode 58b, lead 60, motor 52 and diode 64 to collector 57. Conversely, if the polarity of the current applied to collectors 55 and 56 both are negative, as when vehicles 18 and 20 both are in the inner lane, then si~ch negative currents ap~ear as concurrent negative half-cycles. ~evertheless, current continues to flo~ through motor 52 in the same direction as ~hcn the currents are. positive.
That is, current 10ws from collector 57, throu~h diode 62, motor 52 and both diodes 58c and 58d to coll.ectors .55 a.nd 56, respcct.ively.

Since it is normally desirable Eor the shiftable vehicles 18, 20 to be operating on the outermost track of the game, except durin~ passing on the inner lane, the notors of the shiftable vehicles normally receive current of the polar-ity used to keep the shiftable vehicles 1~, 20 in the outer lane. Tnus the diodes 36 are arranged to permit only current of that polarity to pass to the motor. When both shiftable vehicles 1~ and 20 are in the outer lane and supplied with current of the same polarity the motor 58 will receive only half wave voltage through rectifier 36 and thus will be driven from the contact strip having the highest voltage. On the other hand, if one steerable vehicle is in the outer lane and one is in the inner lane then the drone car will receive full wave volta~e through rectifier 36 and the bridge of Figure 6.
T~ld~ o~t~ge i~ ^ont~ct s~rip ~ i~ positive and volt~ge in contact strip B is negative then, during the positive hal.-cycle, current flows from collector 55, through diode SSa, lead 60, motor 52 and diode 58d to collector 56; while during the next negative half-cycle, current flows from collector 56, through diode 5~b, lead 60, motor 52 and diode 5~c to collector 55. As a result of receiving iull w~ve voltage, the drone car' 5 speed will increase in this embodiment~ w~len one o the shit-able vehicles is moved to the inner lane to pass.
In those instances where both shiftable vehicles 18, 20 are operated to shift them into the inner lane, so that the polarity of current in both strips A and B is opposite to that permitted by diodes 5~ to pass to motor 52, the motor will continue to ~rive vehicle 22 and it ~.il.l receiv2 half wave voltage as diodes 62, 64 ~7ill permit current to pass ~rom ground conductor 57 through diode 62 to motor 42 and then to _g _ .

br:idge 54. Thus, regardless of the combination of p~larities in conductor strips A and B (i.e. both positive, both negative, a one positive and one negative) the drone will always 7~ove in the forward direction under the influence of the conductor strip having the highest voltage of the proper polarity.
Pre~erably the gear transmission 48, 49 in vehicle 22 is selected to have a gear ratio such that the maxi7~um speed of vehicle 22 will be less than the speed of the v~hicle associated with the conductor strip supplying current to ~he - drone. That is, the gear ratio is such that the maximum speed o~ the drone will be proportional to the maxiTnu~ speed of the controllable ve'.~icle. At present, ;t is believed that: a seventy percent (70%) ratio is desirable. This is important, in addi-tion, since when one vehicle is moved out of the outer ~ane to the inner lane and arone 22 receives L7~1L w~vc voltage i~:s speed will incre~se and the gear reduction ratio will insure that the controllable vehicle can speed up fast enough to pass the drone.
In order to avoid increasing the speed of the drone car when one of the controllable vehicles is operated to pass. ;~
the drone car, the control circuit for supplying current to the controllable vehicles 18, 20, can be modif~ed, as shown in Figure 7. In this embodiment of the invention, the power suppl~J from the half ~7ave rectifier 36 to the controller B for vehicle 20 is reversed, as is the drive motor in the vehicle itself, with the result that vehicle 20 will remain in the outer lane and drive iTI a forward direction ~7'nen ne~ative polarity current is supplied to i~s motor while vehicle 18 controlled by controller 24 will remain i~ the outer lane when positive current is supplied to its motor. In this manner, in ~10 -- the typical operation of the game, with both vehicles 18 and 20 in t:he outer lane, positive pvlarity current will be present in t:he collector strips A w'nile negative polarity current will be present in the collector strips B. Thus the motor in the drone car (wnose control circuit remains the same as in Figure 6) receives full wave current from the tracks A and B through t~.e half wave rectifier 36, in the s~me manner as described above with respect to the embodiment of Figure 5 when one car is on the inner lane and one is in the outer lane. That is, the positive phase of the A.C. current flows through line 55 to the brid~e 54 (through diode 58a) and then to the motor 52 through the lead 60, while the negative phase of the ~.C.
curl-ent, which is 1~0 out of phase from Lhe positive phase, flows through Lhe ground collector 57 to cli.ode 62 and motor 52.
1J ) Thus, with the circuit o~ ~'igure 7, wnen ~oth controiiabie vehicles 1~ and 20 are in the outer lane, drone vehicle 22 will be driven at its maximum speed, dependent upon the speed at which the controllable vehicles are driven.
With this embodiment of the invention when one of the toy vehicles is swltched to move to the inner lane in order to pass the drone car~ then both vehicles in the inner and outer lane will have the same polarity current supplied to its motor. For exa~.ple, when the vehicle 20 is moved to the inner lane, the current supplied thereto is switched from negative to positive, so that both vehicle 18 and 20 receive positive polarity current. As a result t~e vehicle motor 52 receives only positive half-wave current from the rectifier 36, and will slow down somew'rat and mt~ve ~t a sl)~ed ~ ich is proportional to the speed of the fas~est rQ~:;n~ of the two vehlcles 18 ~nr1 ^0~ -~On She other handt if vehicle 1~ were J
.. - S
moved to the inner lane, so that the current supplied to it was switched from positive to negative, with both vehicles 18 and 20 thus receiving negative polarity current, then again the motor of the drone car receives only half-wave current, and again moves only at a speed which is proportional to the speed of the fastest moving of the two vehicles. Thus again the drone car will slow do~n slightly while still presenting an obstacle in the outer lane which must be passed by the control-lable toy vehicles. This facilitates passage of the drone car by the controllable toy vehicles.
~y the above described arrangement t'ne drone car will contin~ously operate on track 12 wherever one of the controll-able vehicles 18, 20 is operated. Its speed will always be slower than the speed of the fastest car movin~ on the track and as it moves along the track, wili vary i~ n~,Led.c~
manner as the players vary the position and speed of their respective controllable vehicles, yet it will always move slower than those vehicles' maximum speed to provide an obstacle on the track which must be passed.
Accordingly it is seen that a relatively simply con-structed vehicle and toy vehicle game is provided in which a drone vehicle moves along the track at an unpredictable rela-tively slow speed while being driven by current supplied from strips loca~ed in the track.
Althoùgh an illustrative embodiment of t~e present invention has been described herein with reference to the ~_companying dra~ings, it is to be understood that the inven tion is not limited to that precise eln~o-limen~, and that ~arious changes and modifications may be effected therein by one skilled in the art without departin~ from the scope or spirit of this invention.

~he'control system 30 for the toy vehicle game ~s sho~m schematically in Figure 5 and includes, in addition to the respective controllers 24, a plug 32 by which the system can be connected to an electrical AC power source and a trans-former 34. Power is su?plied from transformer 34 through a half-wave recti~ier 36 including two diodes connected as sho~n to separately supply current to the controllers 24, 26. ~ach 'controller is provided as a hand held unit and incl.udes a ' variable resistor 38, operated as a trigger on the unit, as we'Ll as a single pole double throw switc'l 40. Current fro~
controller 24 is supplied through its variable resistor 38 to the contact strips A and current from the controller 26 is supplied through its variable resistor to the contact strips B. The variable resistors may be of any convenient construc-tion to permit the operators to vary the current supplied to their respective contact strips, and thus their respective vehicles, in order to vary the speed of the vehicles.
The polarity of the current supplied to the toy vehicles is separately and independently controlled by switches 40 so that the polarity of current supplied to the motors of the respdctive vehicles, as controlled by ~he respective con-trollers, will vary in accordance with the position in which the switches l~0 are placed. By this arrangement each player, , using his controller 26 or 24, can control the speed ~f his vehicle along the track 12 and he can also variably position his vehicle along the track si~ply by changing the polarity of current supplied to the vehicle. As described above the polarity of the current supplied to the motor of the respec-tive toy vehicles will determine which of the two rear dri.ve wheels is powered, and this will determine which lane the vehicle will be driven in. In this embodiment of the inven-tion, the motors in the toy vehicles 18, 20 and the current supply circuit of Figure S are arranged such that the left drive wheel of the vehicleswill be driven when posltive polar-ity current is supplied thereto and thei,r,right drive wheels will be driven when negative polarity current is supplied thereto. For example, lowermost diode 36 is adapted to conduct during Positive half-cycle~ of the alternatitlg current and uppermost diode 36 is adapted to conduct during negative half-cycles of the alternating current. I~hen a switch 40 of one of the controllers engages a left-hand contact, posit~ve current 10ws from transformer 34, lowermost dio'de 3~, switch 40 and variable resistor 38 to a corresponding track (A or B), and thence through the motor o the respec~ive vehicle to track C. If the switch 40 engages a right-hand contact, then negative current flows from transformer 34, upper~.ost diode 36, switch 40 and variable'resistor 38 to the corresponding track (A or B), and thence through thé motor of the respective vehicle to track C.
~s illustrated in Figure 1, when it is desirecl to switch a vehicle from the ou~er lanc to t!,e innel^ lane, as shown with vehicle 20, the polarity of current supplied to the vehicle is selected to drive the outer or right ~heel of .. . . .

the vehicle thereby moving the vehicle leftwardly into ~he inner lane. Likewise, when it is desired to move the vehicle outwardly the inner or left wheel of the vehicle is driven, by properly selecting the polarity of current supplied to the motor of the vehicle, so that the vehicle will move ~oward the right and into the outer lane. Thus the operators have complete control over both the speed of the vehicle and the lane in which the vehicle will move.

~ 2 play value of the game as all players will have to pass the drone car during tne game at some stage of operation of the game, and this introduces a further variable factor into the game requiring an additional degree of skill and vehicle S control in order to win the "race".
Drone car 22 includes a frame 42, plastic body 43, and a pair o~ front and rear drive wheels 44, 45 respecti~ely.
The front wheels are preferably mounted in a slight angular relation to the longitudinal axis of the body so that the 1~ vehicle will always be driven toward and against one of the side walls of tlne track. Thus, as illustrated in Figures 3 and 4, the frame 42 has front ~heel mounts 46 which are formed ,at angles to the longitudinal axis of frame 42, with ~heels 44 being rotatably mounted thereon, so that wheels 44 are canted slightl~J to the right so the vehicle will stay in the outer lane of the track. If the front wheels are instead canted to the left the vehicle will stay in the inner lane of the trac~.
Alternately the front wheels can be aligned straight on the frarne. In that case, because of the e~fects ol centrifugal force the drone car will normally move in the outer lane against outer wall 30, even if it is initially placed in the inner lane 16, because as the vehicle passes around a turn in the track it will be thrown by centxifu~al force into the outer lane against outer wall ~0.
The rear drive ~heels 45 àre fixed on a rear drive shaft 47 which has a centrally located spur gear 4~ rigidly secured thereto. This spur gear is driven through a worm gear 49 mounted on the output shaft 50 of an electric motor 52 molmted on rarne 42. Current is supplied to the motor 52 from the contact strips on the track through a current control .. . _ ' , ' _ , . . ..
:~ ~
circuit 53 (Figure 6), ~Jhich includes a diode bridge 54, and a plurality of collector strips 55, 56, 57 mounted on the lower surface of frame 42 of the vehicle. These collector strips are or~ed of flexible metallic material and are removably mounted on the bottom of the frame 42 in any convenient manner. The collector strip 57 is located to contact strips C, i.e. the strips of the track connected to the ground, while contact strips 55, 56 are positioned to contact strips A and B, respectively and continuously pick up current from the track.
Collectors 55, 56 are electrically co~nected to the diode bridge 54 to supply current to the bridge. Since i~ is necessary to supply current to the motor 52 of only the polar-ity which will drive vehicle 22 in the forward direction, the diodes 58 o~ bridge 54 are arranged to pe~mit current flow to -1~ ~ly ~r,^ 3~ c~ ct^~ ~ Th~ls th~ rr~ to~s r~,n c~l lert ~urrent from each o~ the strips A, B and C to supply current of prc~er polarity to motor 52. That is, if the polarity of the current applied to collectors 55 and 56 both are positive, then such positive current appears~s~current positive half-cycles. .
Hence, positive current flows from col.lector 55, through. diode 58a, lead 60, motor 52 and diode 64 to collector 57. Also, positive current flows from collector 56, through diode 58b, lead 60, motor 52 and diode 64 to collector 57. Conversely, if the polarity of the current applied to collectors 55 and 56 both are negative, as when vehicles 18 and 20 both are in the inner lane, then si~ch negative currents ap~ear as concurrent negative half-cycles. ~evertheless, current continues to flo~ through motor 52 in the same direction as ~hcn the currents are. positive.
That is, current 10ws from collector 57, throu~h diode 62, motor 52 and both diodes 58c and 58d to coll.ectors .55 a.nd 56, respcct.ively.
, 6~
.
Since it is normally desirable Eor the shiftable vehicles 18, 20 to be operating on the outermost track of the game, except durin~ passing on the inner lane, the notors of the shiftable vehicles normally receive current of the polar-ity used to keep the shiftable vehicles 1~, 20 in the outer lane. Tnus the diodes 36 are arranged to permit only current of that polarity to pass to the motor. When both shiftable vehicles 1~ and 20 are in the outer lane and supplied with current of the same polarity the motor 58 will receive only half wave voltage through rectifier 36 and thus will be driven from the contact strip having the highest voltage. On the other hand, if one steerable vehicle is in the outer lane and one is in the inner lane then the drone car will receive full wave volta~e through rectifier 36 and the bridge of Figure 6.
T~ld~ o~t~ge i~ ^ont~ct s~rip ~ i~ positive and volt~ge in contact strip B is negative then, during the positive hal.-cycle, current flows from collector 55, through diode SSa, lead 60, motor 52 and diode 58d to collector 56; while during the next negative half-cycle, current flows from collector 56, through diode 5~b, lead 60, motor 52 and diode 5~c to collector 55. As a result of receiving iull w~ve voltage, the drone car' 5 speed will increase in this embodiment~ w~len one o the shit-able vehicles is moved to the inner lane to pass.
In those instances where both shiftable vehicles 18, 20 are operated to shift them into the inner lane, so that the polarity of current in both strips A and B is opposite to that permitted by diodes 5~ to pass to motor 52, the motor will continue to ~rive vehicle 22 and it ~.il.l receiv2 half wave voltage as diodes 62, 64 ~7ill permit current to pass ~rom ground conductor 57 through diode 62 to motor 42 and then to _g _ .

br:idge 54. Thus, regardless of the combination of p~larities in conductor strips A and B (i.e. both positive, both negative, a one positive and one negative) the drone will always 7~ove in the forward direction under the influence of the conductor strip having the highest voltage of the proper polarity.
Pre~erably the gear transmission 48, 49 in vehicle 22 is selected to have a gear ratio such that the maxi7~um speed of vehicle 22 will be less than the speed of the v~hicle associated with the conductor strip supplying current to ~he - drone. That is, the gear ratio is such that the maximum speed o~ the drone will be proportional to the maxiTnu~ speed of the controllable ve'.~icle. At present, ;t is believed that: a seventy percent (70%) ratio is desirable. This is important, in addi-tion, since when one vehicle is moved out of the outer ~ane to the inner lane and arone 22 receives L7~1L w~vc voltage i~:s speed will incre~se and the gear reduction ratio will insure that the controllable vehicle can speed up fast enough to pass the drone.
In order to avoid increasing the speed of the drone car when one of the controllable vehicles is operated to pass. ;~
the drone car, the control circuit for supplying current to the controllable vehicles 18, 20, can be modif~ed, as shown in Figure 7. In this embodiment of the invention, the power suppl~J from the half ~7ave rectifier 36 to the controller B for vehicle 20 is reversed, as is the drive motor in the vehicle itself, with the result that vehicle 20 will remain in the outer lane and drive iTI a forward direction ~7'nen ne~ative polarity current is supplied to i~s motor while vehicle 18 controlled by controller 24 will remain i~ the outer lane when positive current is supplied to its motor. In this manner, in ~10 -- the typical operation of the game, with both vehicles 18 and 20 in t:he outer lane, positive pvlarity current will be present in t:he collector strips A w'nile negative polarity current will be present in the collector strips B. Thus the motor in the drone car (wnose control circuit remains the same as in Figure 6) receives full wave current from the tracks A and B through t~.e half wave rectifier 36, in the s~me manner as described above with respect to the embodiment of Figure 5 when one car is on the inner lane and one is in the outer lane. That is, the positive phase of the A.C. current flows through line 55 to the brid~e 54 (through diode 58a) and then to the motor 52 through the lead 60, while the negative phase of the ~.C.
curl-ent, which is 1~0 out of phase from Lhe positive phase, flows through Lhe ground collector 57 to cli.ode 62 and motor 52.
1J ) Thus, with the circuit o~ ~'igure 7, wnen ~oth controiiabie vehicles 1~ and 20 are in the outer lane, drone vehicle 22 will be driven at its maximum speed, dependent upon the speed at which the controllable vehicles are driven.
With this embodiment of the invention when one of the toy vehicles is swltched to move to the inner lane in order to pass the drone car~ then both vehicles in the inner and outer lane will have the same polarity current supplied to its motor. For exa~.ple, when the vehicle 20 is moved to the inner lane, the current supplied thereto is switched from negative to positive, so that both vehicle 18 and 20 receive positive polarity current. As a result t~e vehicle motor 52 receives only positive half-wave current from the rectifier 36, and will slow down somew'rat and mt~ve ~t a sl)~ed ~ ich is proportional to the speed of the fas~est rQ~:;n~ of the two vehlcles 18 ~nr1 ^0~ -~On She other handt if vehicle 1~ were J
.. - S
moved to the inner lane, so that the current supplied to it was switched from positive to negative, with both vehicles 18 and 20 thus receiving negative polarity current, then again the motor of the drone car receives only half-wave current, and again moves only at a speed which is proportional to the speed of the fastest moving of the two vehicles. Thus again the drone car will slow do~n slightly while still presenting an obstacle in the outer lane which must be passed by the control-lable toy vehicles. This facilitates passage of the drone car by the controllable toy vehicles.
~y the above described arrangement t'ne drone car will contin~ously operate on track 12 wherever one of the controll-able vehicles 18, 20 is operated. Its speed will always be slower than the speed of the fastest car movin~ on the track and as it moves along the track, wili vary i~ n~,Led.c~
manner as the players vary the position and speed of their respective controllable vehicles, yet it will always move slower than those vehicles' maximum speed to provide an obstacle on the track which must be passed.
Accordingly it is seen that a relatively simply con-structed vehicle and toy vehicle game is provided in which a drone vehicle moves along the track at an unpredictable rela-tively slow speed while being driven by current supplied from strips loca~ed in the track.
Althoùgh an illustrative embodiment of t~e present invention has been described herein with reference to the ~_companying dra~ings, it is to be understood that the inven tion is not limited to that precise eln~o-limen~, and that ~arious changes and modifications may be effected therein by one skilled in the art without departin~ from the scope or spirit of this invention.
