Description
FIELD OF INVENTION

The present invention is related to amusement devices generally depicting simulation of vehicle travel or racing. In particular this invention relates to vehicles which are electrically powered and guided by a slot or groove in a simulated raceway or path.

BACKGROUND OF INVENTION

The invention pertains to the activity or hobby of slot car or model car racing. For nearly 40 years this activity has utilized rubber or plastic roadway or track which is fitted with two electrical rails for each given lane. The electrical power, typically direct current (DC), passes through a means of varying voltage to the track and thus the electric motor inside the toy vehicle which would vary its speed on the track.

The challenge aspect of the hobby was increased by an introduction of modular track pieces to vary track layouts. In addition timing and lap counting were added and are generally accepted as common within the art. To improve the aspects of challenge and realism various types of slotless track systems, vehicle steering systems and racing elements have been invented or attempted.

In pursuit of a more accurate portrayal of automotive racing U.S. Pat. No. 6,109,186 issued to David Smith and David Brobst is a slot racing system which introduces a working vehicle race pit stop which includes tracking of fuel usage and refueling, tracking tire wear and replacement as well as random events which affect the performance of the electric toy vehicle on the slot track. However, that invention severely limits the number of active users and precludes the user of the system to interactively control pit stop functions. Nor does that system allow realistic vehicle control functions such controlling vehicle lights, brakes, and actually steering into or out of a desired lane or pit stop location. In addition the system only allows for a single vehicle per lane which forces entry to the pits from an outside lane by at least one toy vehicle which is unrealistic from the standpoint of a realistic race simulation.

U.S. Pat. No. 6,688,985 issued to Steven N. Weiss and Gerhart P. Huy, et al. proposes an interactive, electronically controlled racing game which provides aural and visual feedback via graphical LCD panel attached to a base unit. That system monitors fuel usage and tire wear and allows input from the user via a button to manipulate the events related to the pit stop. While that invention improves on the interactivity between the user and the toy, it too only allows a single vehicle per lane, thus forcing vehicles to “pit” in two lanes which, too is unrealistic from a racing simulation point of view. While the pit function indicates some sort of attention is needed, it does not allow the operator to either bypass or partially address a particular problem and accept the consequences of his actions in the interest of saving time. Lap counting and timing by design are limited to 1 00 laps and 1/100th of a second which is not suitable for realistic racing simulation.

U.S. Pat. No. 5,218,909 embodies a slot track wherein the toy vehicles change lanes. The vehicles specified in that case are radio-controlled and thus not of the commonly conceived method within the slot racing hobby of having the track supply power to the toy vehicles.

U.S. Pat. No. 4,382,599 issued to Neil Tilbor introduced a method of racing slot cars which allowed the changing of lanes in a manner similar to realistic driving. With the touch of a button the user could make his or her vehicle change lanes. However, centrifugal force would change your lane on a curve while using this invention, taking control from the user. In addition, no realistic means for lap counting or timing is there identified.

Finally, within the art it is common that one vehicle is allowed per lane. This forces an individual to add numerous parallel lanes in order support a larger field of vehicles. This often has a negative impact on available space and the available designs of the resulting race course.

U.S. Pat. No. 6,883,720 issued to V. J. D'Angelo, Jr. et al. proposes locating guide slots in close parallel in order to simulate a chicane. That invention forces vehicles in closer proximity for a time in order to enhance the excitement of the racing experience. While innovative, this art continues to restrict the racing simulation to only two toy vehicles and includes no other unique, interactive functionality. It certainly does not provide for lane changing as does this invention.

In addition to creating a more realistic racing environment, the objective of this invention is to introduce a means for controlling multiple brands of toy slot vehicles which reduces heat and wear to their motors while protecting the investment of the individual in control devices. Unlike other control devices, the control means of this invention accommodates customization without opening the device or requiring technical skill. While it is best to match controller performance to vehicle performance, controllers available today are difficult or time-consuming to customize. Thus some purchase multiple, pre-configured controllers or endure an unsatisfying experience attempting to control a slot car for which their controller is not suitably matched. The control means introduced in this invention provides the operator with greater control over their environment, an experience which enhances enjoyment and offers a control device that proves to be a more sound and lasting investment.

BRIEF DESCRIPTION OF INVENTION

The invention comprises a system that allows for a more realistic racing simulation that previously provided on an electrically powered, continuous loop, slotted racing surface. Components of the invention include durable plastic, slotted track surfaces where each slot is flanked by pairs of rails which allow multiple vehicles to race in a single lane. The vehicles are also allowed to change lanes upon command at selected points on the track.

The size of the field of vehicles is determined by multiplying the number of rails on the left side of the slot by the number of rails on the right side. Operating multiple vehicles in a single slot is accomplished by selective sharing of the grounding wire for a group of positive leads on the opposite side of the slot. Vehicles have electrical pickup shoes which can be arranged in such a way that each uses a unique combination of rail pairs. That unique shoe-placement and rail positioning configuration also allows uncomplex vehicle recognition by mechanisms which provide or monitor lane changing, lap counting, timing, pit stops and vehicle functions such as lights and brakes.

A unique hand-held control mechanism is specified with which the toy vehicle can be steered into lanes chosen by the user. Toy vehicle lights can be activated by each individual user, pit stop functions can be controlled. Vehicle lighting system will recognize input from the user via a digital signal on the track system which is the subject of this invention or will operate in automatic mode on other analog track systems. Brake lights on the toy vehicle may be operated by issuing the braking command on the hand-held controller. Dynamic braking is achieved via back electro-magnetic field which can be activated between speed power pulses, allowing braking and acceleration functions to operate simultaneously when the throttle is not at 100%. The hand-held device controls speed via pulse width modulation. The hand controller supports a mode allowing for control of analog vehicles as well as vehicles controlled via the microprocessor described herein. Hand held device will interpolate pulsed power signals with pulsed data signals to the microprocessor means within the vehicle on the positive side of the direct current wave. The power pulse goes over a zener voltage while the data signal is under the zener voltage. The hand held device can operate a vehicle using a variety of power and performance curves which are stored on the microprocessor.

DETAILED DESCRIPTION OF THE DRAWING

A base unit 2 as appearing in FIG. 1 connects to at least one track segment 5 which uses a plurality of electrically conductive rails 3 and a slot 27 for the guide flag of an electrically powered toy vehicle 4. The control unit allows vehicle travel and lap counting for vehicles traveling either in clockwise or counter-clockwise direction via a switch 8 mechanism. The base unit 2 supports a plurality of vehicles 4 and thus hand held control units 9 via connections 10 for hand held control units 9 or other accessories which may include lighting and otherwise. The base unit 2 is comprised of simple electrical components, allowing connection of analog hand controllers for select third parties. The base unit 2 also supports multiple DC power supply devices via power ports 1. The track segments include an electrical and mechanical means for interconnection (not shown).

A combination of base units 2 may be configured to support their maximum number of vehicles simultaneously on the same track to which they are interconnected. Lap count and timing may be displayed on an optionally attached display 14. That display allows operator to select modes of racing such as though not limited to rally, Max Laps, Timed Endurance, qualifying, etc. via button control devices 6. Lap Timing, counting, racing mode selection as well as pit functions are to be controlled via microcontroller device.

As seen in FIG. 2, voltage from multiple sources simultaneously is supported. Schematic tags C1A-C1E show the connection between the hand control unit 9 of FIG. 1 and the base unit. The “Polarity Manager” controlled by the switch 8 in FIG. 1 governs the flow of electricity to the conductive rails 3 and accessories such as lap counting/timing as well as pit stop control devices which may or may not be integrated into a base unit. The LED device allows connection to an external starting light system which is associated with the race start function. Flow of current to track segments may be affected either by timing or pit stop events via transistor “Q” through connection identified as tag PI1. Pit stop and timer/counter activator switches are integrated with certain track segments. A voltage regulator protects such segments from over voltage via the power line identified as “L1”. “PC1” reflects UART communication timing and/or pit stop information to an external computing device such as a personal computer.

The schematic representation of FIGS. 3A to 3C show the unique method here employed for the purpose of sharing an electrical ground wire. The diagram shows how multiple hand control units 9 use a uniquely controlled “powered” line 30 and a shared ground in order to achieve unique control and communication to a particular electrically powered toy vehicle (4 as appears in FIG. 1). In this diagram “A” and “B” represent ground circuits for two unique DC power supplies or sources 29. Multiple power and ground rails are situated on either side of the slot 27 in a track segment. A motor 28 and an optional decoder device (not shown, See FIG. 12) would be powered using this methodology providing unique control to an individual operator.

The device shown in FIG. 4A would be attached to the underside of a particular track segment. The device is comprised of at least one push type solenoid 34, two pushrods 32, a “left turn” diverter 31 and a “right turn” diverters 33 and springs which will return the diverters to their non-activated state. The activation of either “right turn” or “left turn” diverters will activate diverters on either entry or exit side of the lane change device of FIG. 4B. This allows the lane change device to work the same way in either direction without the need for additional solenoids. The diverters will enter the path of the slot at an angle of approximately 10 degrees, forcing the vehicle either left or right on the track. The flanged end of each diverter will make contact with a stop on an adjoining track segment preventing diverter from enter the path of the slot inadvertently. An attached microprocessor allows the unit to accept steering input from a driver, automatically divert a particular vehicle after identifying it via the pair of rails it uses, detect and avoid collision be deactivating lane change if a collision is imminent. This track section also allows the user to selectively bias the steering in a certain direction in a way that steering in the opposite direction will deactivate the bias for a particular driver or vehicle.

The lane change track segment 7 shown in FIG. 4C includes diverters 31, 33, electrically conductive rails 3 on either side of the slot 27. The drawing also shows unique notches 18 which allow a vehicle to pass from one lane change track segment 7 to another adjoining segment so that more than two lanes are accommodated on a racing circuit. FIG. 4D shows the track segments 7 implemented as single lane segments and in a group of four segments though the detail of conductive rails is not shown.

The schematic of FIG. 5 shows integrated circuits which contain relay devices. The current from the hand held controller flows into either J3 or J4 depending on the polarity which is determined as per the discussion of FIG. 1. The current would flow through the relay switches via power connections P1-P12 of the integrated circuits PR1-PR3 to the rails of the lane change or pit device J1 and J2. The relays are only activated when a combination of rails in J1-J2 are activated by being in contact with the vehicle guide as seen in FIG. 9, number 20. A matching combination of relays RLY1-RLY4 having current flowing through them indicates a request to change lanes by an operator via hand controller unit to connections J5 and J6. The direction of the current indicates the requested direction of the lane change. Connections J7 and J8 will respond to only one current direction respectively. Control of current flow to these connections is managed by the diodes marked “D” in FIG. 5. Current would flow to either of the push-type solenoids of FIG. 4A, number 34 if this is a lane change track segment. However, current would active one of two control mechanisms controlling pit stop or other accessory functions should this track segment serve as a pit control or other accessory segment. The electronic circuit allows for control of an endless array of interactive track segments and thus a variety of racing, driving or chase “games” which could be played. Lap counting, timing and vehicle identification at pit stops will also use this method of identifying unique rail pairs use by a specific vehicle.

Referring to FIG. 6, the hand control device 9 there depicted is designed to provide the operator a device which is durable and customizable allowing the control device to accommodate a variety of vehicles and their unique performance characteristics. In addition, the device allow for a more realistic driving experience by implementing a steering device 11 whose functions can be mimicked in a one-hand operating using the steering control set of function buttons 13. Other buttons 13 allow for control of lighting effects and an enhanced mode which would be required by certain accessories such as the pit stop accessory. The trigger may be configured to serve as a throttle when the trigger is pressed and an active brake when the trigger is pushed away. An active brake may also be implemented as a separate button control mechanism (not shown). Controls are provided to allow selection of a predetermined power and acceleration curve 15 as well as braking strength 17 to accommodate the weight and characteristics of different toy vehicles. This device, when wired properly should function in standard mode for any analog-controlled toy vehicle on any track system whose electrical characteristics match those of the native system of this hand held control device.

The electronics supporting the functions within the hand held control unit are shown in the schematic of FIG. 7. SW1-SW4 are contact switches which affect enhanced functions such as pit stops. Other functions for those switches include turning head and tail lights off and on, sending a nominal voltage to the track surface when steering is activated so that one can coast and steer through track segments simultaneously, other vehicle accessory function yet to be determined such as sound.

VR1 and VR2 are analog inputs to the pulse width modulation output which controls vehicle speed. VR3 regulates resistance during dynamic braking. Q1 MOSFET controls the power pulses controlling vehicle speed. The Q2 MOSFET is responsible for sending actual data signals to decoders and affecting the flow of power pulses to the motor. Q2 MOSFET takes precedent over Q1 MOSFET. Thus power pulses from Q1 will not reach vehicle/decoder during periods when Q2 is inactive. This is how the data signal is superimposed over power pulses. If no power pulse is active via the trigger then 6 volt data pulses will be sent over the conductive rails upon activation of Q2. 6 volts is under the 7 volt zener in the decoder. Pulses at that voltage are read as data packets by the decoder, but are not high enough to pass zener voltage and thus power the motor of the vehicle when enhanced control is activated via the hand control unit.

Q3 activates a short circuit between a specific pair of rails so that dynamic braking is activated for a spinning engine connected to those rails.

Programming logic will keep Q3 and Q2 from be active simultaneously as this would short out the system. When the braking function is activated, the brake Q3 will only be active during the period of time during the duty cycle when such cycle is less than 100 percent. This allows user to use accelerator and brake simultaneously if desired to fine tune acceleration and deceleration when their vehicle is turning or otherwise. Voltage regulars and protection diodes are used to protect the circuitry. FIGS. 11A to 11C show the waveforms for speed/power pulses, signal pulses and a signal pulse superimposed on a power pulse. Notice the signal pulses coming in under the zener voltage for the decoder identified in FIG. 12.

FIGS. 8A to 8C depict various views of the unique guide 20 mechanism of this invention. The guide may be attached to the toy vehicle using either a self-retaining method or a retaining screw 36 and washer. Since electrical pickup shoes 22 may be positioned by the operator on the guide 20 it is important the electrical contact is made between the pickup shoes 22 and the engine/decoder via the conductive wires 21. Since the shoes can be placed in any position the conductive plates 24 are used to maintain that contact across a predetermined width.

To enhance the realism of the race experience, this invention introduces a pit stop function. This function would monitor the status of critical resources during a race. The display of the various statuses of these resources is depicted in FIGS. 10A to 10C. Such a display may be part of an integrated accessory with an LCD display or part of an external computing program and display mechanism. In either case pit status would be associated with a particular vehicle and would reflect the usage of limited resources. Positioning the toy vehicle on a certain track segment and activating “left” or “right” control mechanism as discussed per FIG. 6, number 13 would allow selection of a resource to renew as well as a choice to replenish that resource. The need to “pit” may be communicated audibly or visually with flashing symbols such as fuel, tires and repair as appearing in FIGS. 10A to 10C.

This invention proposes a means whereby the operator can communicate to his or her toy electric vehicle with the intent of activating or deactivating accessory functions such as lights. A decoder chip is proposed for this function as a receiver of requests from the operator. The schematic of FIG. 12 shows the logic behind this decoding device. This device is not necessary to operate lane change functions, lap counting or lap timing. I would likely be necessary for pit stop function control. In FIG. 12, a voltage regulator is used to manage current going to integrated micro control device. Capacitor C1 should maintain current to VCC of the chip keeping its memory from resetting due to the use of pulsed power. D2 is a zener diode of approximately 7 volts for the motor M. Q2 is a normally closed transistor device which allows the vehicle with this decoder to operator in analog mode by default. Activating Q2 puts the vehicle in enhanced mode, separating data pulses from those above 7 volts which would power the motor. Port PBO reads input data pulses. Capacitor C2 is to power the brake light DL2 with higher voltage to make it brighter when power is not present and dynamic braking may be in effect. The same capacitor C2 would also power the headlights DL1 during periods when headlights are desired and no current is flowing. Of course this power would be temporary. However, a miniature, rechargeable battery may be used in place of C1 or C2. R2 would reduce the voltage and thus brightness of the tail lights during periods of normal operation when current is flowing. Transistor or MOSFET device Q1 is normally closed just as Q2 is, making head and tail lights operate in analog mode by default. However, activating Q2 selectively in enhanced mode will turn lights off or on. The system also allows flexibility so that auxiliary functions may be activated and lighting configuration is customizable manually by the operator. The activation signal is retrieved from the hand held control device.
