BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toy car for use in a toy car game zone, and more particularly to a toy car that can be individually controlled by a player to move from one lane to another and overtake another car.

Toy car races using "slot tracks" are gaining in popularity, and staggering lanes to make them more interesting seem to change lanes. In reality, however, cars always run on track only.

Such a conventional automobile game zone is limited in interest since only speed control is possible, and thus, there are many attempts to allow a car to actually move from one lane to another without being limited to a guide groove. In these attempts, a solenoid-driven bumper has been used to switch lanes by mechanically pushing the vehicle in the other lane. However, such a device is not sure of lane movement, and especially at low speeds, satisfactory results are not obtained. Another example is the use of motor vehicles with relatively complex controls that are controlled by the interruption of the current by opening and closing the switch.

This was not only complicated control, but also the drawback that the speed of the car is reduced by the current interruption.

Another developed lane movement method is to use the control by changing the polarity of the current supplied to the driving motor of the vehicle. In this case, there is an advantage that does not lose speed because there is no interruption of the current, but there is a problem in wear and maintenance management because a lot of rotating parts are required in the control unit.

Another example is the remote control using a solenoid-controlled control, but this also has a complex flaw.

It is an object of the present invention to overcome the drawbacks of the conventional toy vehicle game field, to provide a toy car game field that can be rotated and change lanes without being limited by the guide track or the like.

It is a second object of the present invention to provide a toy car which can move along a lane and change its lane by adjustment of a competitor.

It is a third object of the present invention to provide a toy vehicle in which each vehicle is individually adjusted by the competitor so that lane changes can be made and may even overtake each other.

A fourth object of the present invention is to provide a toy vehicle having a drive transmission of a relatively simple structure that can change the lane of the vehicle in response to the polarity of the electric current supplied to the automobile motor.

A fifth object of the present invention is to provide a toy vehicle having a drive transmission of a relatively simple structure capable of selectively driving any one of two drive wheels of a vehicle in response to the polarity of the current supplied to the motor vehicle. will be.

A sixth object of the present invention is to provide a toy car and a toy vehicle game ball having the above-described characteristics which are structurally relatively simple and can withstand long-term use.

It is yet another object of the present invention to provide a toy car and a toy vehicle game field which can be manufactured relatively simply and inexpensively. According to one aspect of the invention, there is provided a toy car for a toy vehicle game equipment having a frame, a vehicle body mounted on the frame, and a plurality of wheels including a pair of drive wheels. The drive wheels are spaced apart from each other on the frame and are individually rotatable, and electric motors are also provided which can rotate in the reverse direction to selectively drive these wheels. Drive motors are installed in the frame to connect the output of the electric motor to the drive wheels. The drive transmission includes at least one drive element rotatably mounted in the frame, the drive element being moved between the first and second positions in accordance with the direction of rotation of the drive motor to move one of the drive wheels. Drive selectively These toy cars are preferably used in an endless track having side walls with two car lanes. When only one driving wheel of the vehicle is driven by each motor of the automobiles, the vehicle collides with the side wall and travels along the side wall.

The power supply to the motor vehicle is made by electrical contact strips located in the lanes of the motor vehicle tracks. Such a power supply not only allows the competitor to individually control the speed of the vehicle, but also changes the lane of the vehicle by changing the polarity of the current supplied to the vehicle mode. In addition, the vehicle is provided with a shock absorbing shear having a relatively simple structure for absorbing the impact when hit the side wall when changing lanes, and correctly positioning the front wheels of the vehicle in the new lane.

Hereinafter, the object and configuration of the present invention with reference to the drawings in more detail.

The toy vehicle game ball 10 shown in FIG. 1 includes an endless track 12 made of plastic, side walls 14 and 16 provided on both sides of the track 12, and a road therebetween. The road 18 is wide enough to provide at least two lanes 20 and 22 for driving a large number of automobiles.

In the illustrated embodiment, there are cars 24 and 26 that are controlled by a player, and these cars have the same structure except for the current collector (which will be described later) arrangements. In addition, the unmanned vehicle 28 is arranged to travel at a constant speed.

If the player changes the magnitude of the current supplied to each vehicle motor by the controller 30, the speeds of the cars 24 and 26 can be adjusted, and the controller 30 is supplied to each vehicle motor. By changing the polarity of the current, the lanes of the cars 24 and 26 can be changed. The unmanned vehicle 28 is moving at a constant speed along the track, and serves as an obstacle to be overtaken by the cars 24 and 26 controlled by the player. The front wheel of the unmanned vehicle 28 is preferably inclined in either direction so that the unmanned vehicle travels only the inner or outer lane. This driverless vehicle is driven by a battery operated by a battery, the drive transmission of which is similar to the conventional structure of the rear wheel drive.

Toy car 24 is shown in detail in FIGS. The vehicle 24 has a structure in which a plastic vehicle body 34 is attached to the frame 32. A pair of front wheels 36 are rotatably mounted to the frame via a shock absorbing front end 38 (which will be described later), and the rear wheels 40 are mounted on a shaft 42 mounted to the frame 32. It is mounted so as to be rotatable independently (see Fig. 5). One of the rear wheels 40 is fixed to the shaft 42 with a spline 44 or the like, and the other is provided to be freely rotatable on the shaft. In addition, both wheels may be attached to the vehicle side 48 so as to rotate freely. In any configuration, these wheels are driven individually and independently.

In the illustrated embodiment of the present invention, the rear wheel 40, that is, the driving wheel is made of plastic casting or cast metal, and a spur gear 46 is integrally disposed inside the spur gear. Through this the torque is transmitted to the wheels.

The driving force of the toy car is supplied from a direct current motor attached to the frame 32. Emoter is a known direct current motor has a structure in which the output shaft 50 is connected to the rotor. In the embodiment shown in FIG. 2, the spur gear 52 is attached to the shaft 50, which is connected to the transmission 56, which is connected to the spur gear 52. The drive wheel 40 is selectively driven in response to the rotational direction of the motor (that is, the rotational direction of the motor output shaft 50 according to the polarity of the current supplied to the motor).

As shown in FIGS. 2 and 4-6, the transmission 56 has a crown gear 58 and a central collar 62 with teeth 60 extending downwards. A pin 64 is fitted in the collar 62, and the lower end 66 of the pin 64 is fixed to the frame 32.

The crown gear 58 is thus able to rotate over the frame. The collar 62 is fitted with a sleeve 68, which has a shaft extending perpendicular to the axis of rotation of the crown gear 58, wherein the spur gears 70, 72 are It is mounted to be rotatable.

These spur gears 70 and 72 are engaged with the crown gear 58 at an angle to each other (see Fig. 4). Therefore, when the motor 48 is operated, the crown gear 58 connected to the spur gear 52 rotates clockwise or counterclockwise according to the polarity of the current supplied to the motor 48 (first 4 and 6). At the same time, the spur gears 70, 72 are continuously rotated by the crown gear. However, since the spur gears 70 and 72 are mounted on the rotary sleeve 68, the sleeves 68 and the gears 70 and (by the engagement between the gears 58, 70 and 72) are formed. 72 rotates around pin 64 and collar 62. Therefore, as in the case of FIG. 4, when the crown gear 58 rotates in the direction of the arrow X, that is, clockwise, the gears 70 and 72 also rotate clockwise, so that the gear 70 wheels 40 ), The right wheel is driven and the left wheel is free to rotate.

In the game zone shown in FIG. 1, when the driving force is transmitted to the right wheel 40 when the vehicle is in the outer lane, the automobile moves from the outer lane to the inner lane like the automobile 26.

At this time, the front part of the vehicle comes into contact with the inner wall 16 of the track, and if the right wheel continues to be driven, the vehicle travels the inner lane along the wall 16. Of course, when the vehicle is traveling at a curved portion of the track at high speed, it tends to be pushed out to the outer lane by centrifugal force, but if only the right wheel is continuously driven, it can be kept in the inner lane.

Conversely, if the polarity of the current supplied to the motor 48 is changed so that the crown gear 58 rotates counterclockwise, that is, in the direction of the arrow Y in FIG. 6, the gears 70 and 72 are reversed. Direction, the sleeve 68 is rotated in the same direction as the crown gear 58. In this case, the gear 72 is caught by the left driving wheel 40, and thus, when only the left wheel is driven, the right wheel is free to rotate.

As such, when only the left wheel is driven, the vehicle will receive a force to bend to the right, and thus, the vehicle will be moved from the inner lane 20 to the outer lane 22 as shown by the dashed line 24 in FIG. 1. At this time, when the front part of the vehicle hits the outer wall 14, the outer lane 22 continues to travel along the outer wall.

In the above, due to the use of the gears 52, 58, 70, 72, the motor vehicle always runs in the forward direction irrespective of the rotational direction of the output element of the motor, that is, the spur gear 52. Please note.

In order to supply electric current to the toy vehicle, a plurality of contact strips are provided in the lanes 20 and 22 on the raceway 18.

In the illustrated embodiment, three contact strips (A), (B), and (C) are provided in each lane.

These strips are made of an electrically conductive metal and lie on the same plane as the raceway surface so that the car does not get in the way when moving on the lane. The electric current is supplied through these strips as described later, and is received by a current collector installed at a predetermined position of the vehicle frame.

The strips in each lane are paired with each other. That is, the strip A of the inner lane is connected with the strip A of the outer lane, and the strips B and C are connected in the same manner.

The strips (C) are grounded, and the strips (A) and (B) can supply current for each car individually and control their polarity separately, so even if there are two cars in the same lane, It can be controlled independently. For this purpose, the current collector of a vehicle is intended to receive current from a pair of different strips. For example, car 24 receives current from strip B and car 26 receives current from strip A. FIG.

As shown in FIG. 3, the vehicle 24 has two current collectors 111 and 112, and the current collector 112 is in contact with the ground strip C. As shown in FIG.

Motor vehicle 26 has current collectors 112, 114, as shown in FIG. 3A, where current collector 112 is positioned in the same manner as in motor vehicle 24 to contact ground strip C. FIG. It is supposed to be. These current collectors are mounted in motor vehicles in a known manner and connected to the motors 48 of these motor vehicles. The current collector 111 of the vehicle 24 is in contact with the strip B irrespective of the lane.

As shown in FIG. 3, the current collector 111 is located in the center of the vehicle frame. On the other hand, the current collector 114 of the automobile 26 is located slightly away from the center, i.e., opposite to the current collector 112, so that it is always in contact with the strip A regardless of the lane. By arranging such a current collector and strips, each of the automobiles 24 and 26 can be independently controlled in contact with a certain strip A or B in each lane.

The control device 30 of the raceway shown in FIG. 1 is shown schematically in FIG. The controller 30 includes controllers 124 and 126, and the automobiles 24 and 26 are respectively controlled by the controllers 124 and 126. The control device 30 is connected to the AC power supply by a plug 128 and includes a transformer 130. Power is supplied from transformer 130 to each controller 124, 126 via half-wave rectifier 132. The half-wave rectifier 132 includes a diode of thickness, which is connected to supply individual currents to the controllers 124 and 126. Each of the controllers 124 and 126 is capable of manual operation, and includes a variable resistor 134 and a monopole switch 136 for triggering. Current from the controller 124 is supplied to the strip B through its variable resistor 134, and current from the controller 126 is supplied to the strip A through its variable resistor 134. This variable resistor is used to change the current supplied to the vehicle and thus to change the driving speed of the vehicle.

Since the polarity of the current supplied to the vehicle is controlled independently of each other by the switch 136, the polarity of the current supplied to the motor 48 of the vehicle changes depending on the position of the switch 136. With this arrangement, the competitor may change the speed of his vehicle by the controller 126 or 124 and may move the lane simply by changing the polarity of the current. As described above, depending on the polarity of the current supplied to the motor of the vehicle, one of the two rear wheels is driven to move the lane.

When moving a car from an outside lane to an inside lane like the automobile 26 shown in FIG. 1, when the polarity of the current supplied to the vehicle is changed to drive the outer wheels of the car and each of the right wheels, the car is left. To the right and into the inner lane. Similarly, when moving the car from the inside lane to the outside lane, if the polarity of the electric current supplied to the motor motor is properly selected and the inside wheel of the car, ie the left wheel, is driven, the car faces outward. Transferred. In this way, the competitor can freely adjust the lane as well as the speed of the vehicle.

Using the unmanned vehicle 28 traveling at a constant speed as in the illustrated embodiment of the present invention, the unmanned vehicle becomes an obstruction in the outer lane and other cars overtake. In other words, in order to overtake this driverless vehicle, an appropriate lane change is required, thereby increasing the interest of the game.

As described above, the shock absorbing shear 38 is provided in the toy car of the present invention. In the embodiment of FIG. 3, the wheel support plate 130 is pivotally mounted to the frame 32 by the pivot pin 132 on the shock absorbing front end 38. The support plate 130 has a boss portion 134 to which the shaft 136 is fitted, and front wheels 138 are mounted at both ends of the shaft 136. Since the support plate 130 is supported at the center thereof, the front wheels of the vehicle are driven straight by the spring device 140.

The spring device 140 has a tongue portion 142 integrally formed on the plastic support plate 130. This tongue portion 142 is fitted to a pair of projections 144 provided on the frame 32. By such a structure, the support plate 130 and the wheel 138 can be elastically supported at its central position. However, when the vehicle changes lanes and hits one of the side walls (eg, the outer wall 14 of FIG. 8), the support plate 130 rotates in an impact manner, and the shock is absorbed by the spring element, that is, the tongue 142. . At the same time as the support plate is rotated, the wheels 138 are also twisted so that the car can be correctly positioned on the lane, so that the car is located on the contact strip most quickly. In order to increase the shock absorbing characteristic, the bumper portion 146 extends out of the frame in the support plate 130 so as to hit the side wall before any other part of the vehicle.

As shown in FIG. 3A, slots 148 are formed on both sides of the tongue 142 on the support plate 130. The outer end portion 150 of these slots 148 is hit by the protrusion 144 when the support plate 130 is excessively twisted. That is, when the support plate 130 is twisted more than a certain threshold, the side end portion 150 of the slot collides with the protrusion 144 and no longer twists.

In another embodiment of the present invention shown in FIGS. 9 to 11, the position of the front wheel 36 of the toy vehicle 200 is controlled by utilizing the drive rotation of the electric motor 48 to control the position of the vehicle ( It is possible to perform the steering control of 200). In this embodiment of the invention, the toy car has a frame 32 similar to that described in the above embodiment, on which the direct current electric motor 48 is relatively fixed in a known manner. It is mounted in position. There is also a steering panel 202 in the frame, which is pivotally mounted on the toy car so as to rotate relatively freely around its central projection 204. The control panel 202 Saeng is rotatably mounted on the front shaft 206 by a known method such as the boss 211, and is connected to the front shaft by pins or splines so as to rotate simultaneously with each other. These front wheels are to be engaged with the electric gear 208.

The gear 208 is mounted on a central collar 210 that is essentially similar to the collar 68 described in the embodiment of FIG. 2, which collar 210 is rotatably mounted on the central protrusion 204. have. Crown gear 212 is mounted on top of collar 210 on protrusion 204 such that teeth 214 engage gear 208.

The crown gear 212 also engages with the output side spur gear 52 of the motor 48, so that as the spur gear 52 rotates when the motor is driven, the crown gear 212 and the electric gear 208 are rotated. It will be driven in turn.

In this embodiment of the present invention, if the gear 52 rotates in the direction in which the crown gear 212 can be rotated in the direction of the arrow X (FIG. 9), the gear ( 208 rotates counterclockwise (see FIG. 9). As a result, the gear 208 is engaged with the gear 46 of the left front wheel 36, so that the front wheel, that is, the driving wheel, is driven in the forward direction. However, at the same time, as the crown gear 212 continues to rotate, the gear 208 continues to rotate counterclockwise, so that the force toward the left front wheel 36 is applied to the rear. Thereby the steering panel 202 pivots counterclockwise (see FIG. 9), so that the front wheels 36 are tilted to the left. In other words, if the car was in the outside lane of the track 12, as in the case of the car 24 of FIG. 1, for example, the car would move from the outside lane 22 to the inside lane 20, as described above. As in the example, it will be driven against the inner wall 16.

If the polarity of the current applied to the motor 48 is changed through the current collector on the automobile (this current collector is the same as the current collector of the automobile in the above-described embodiment), the output gear 52 of the motor is reversed. Direction, so that the crown gear 212 is driven in the direction of arrow Y (FIG. 11). When the polarity of the current applied to the motor 48 is reversed, the electric gear 208 rotates with the collar 210 clockwise (arrow Y), so that the gear 208 is the gear of the left front wheel 36. It is disengaged from 46 and engages with the gear 46 of the right front wheel 36.

When the gear 208 is engaged with the gear 46 of the right front wheel in this way, the right front wheel is driven in the forward direction. In addition, since the driving force in the rear direction by the crown gear 212 is continuously applied to the gear 208, and the rear force is also applied to the gear 46, the control panel 202 is counterclockwise. By turning the wheels to the right of the car. This causes the car to turn to the right. That is, if the car was in the inner lane in FIG. 1 and the polarity of the current applied to the motor 48 changed so that the front wheels 36 were inclined right as shown in FIG. Will move from the inside lane to the outside lane.

In another form of this embodiment of the invention, the control panel 202 includes a side portion 220 extending beyond the periphery 222 of the frame and acting as a bumper. In this configuration, when the vehicle hits the side wall (for example, the outer wall 14 shown in FIG. 11) on the side to change lanes and proceeds, the bumper portion 220 in the control panel is the first among all the parts of the vehicle. It will hit the side wall.

When the control panel hits the side wall as described above, the control panel moves in a direction opposite to that driven by the engagement of the gear 46 and the gear 208 of the right front wheel. When the control panel 202 is moved in this way, the wheels of the vehicle are immediately aligned along the movement path in the outer track.

However, since the crown gear 212 is driven continuously, the gear 208 maintains engagement with the gear 46 and thus can maintain forward movement of the vehicle. In this way the vehicle can quickly establish its running position along the side wall of the track, so that the current collector of the car can correctly contact the current strip in the track.

)할 수 있도록 위치되어 있으며, 그 폭은 이 크라운 기어의 톱니(228)들이 앞바퀴 내측의 구동 기어(46)들과 교합되기에 충분하도록 되어 있다.Another embodiment of the invention using front wheel drive and steering is shown in FIGS. 12-14. In this embodiment, the vehicle 230 has a frame 32 provided with a direct current motor 48. The tip 232 of the frame 32 has a protrusion 234, on which the crown gear 236 is rotatably mounted. The crown gear 236 engages with the output side gear 52 of the drive motor 48.

The width of the crown gear is sufficient to engage the drive gears 46 inside the front wheel.

The drive gears 46 in this embodiment of the invention are rotatably mounted on the transverse shaft 240, which is rotated on the support block 242 by known prevention. It is mounted as possible.

In addition, the support block 242 is pivotally mounted to the front end portion 232 of the toy car so as to rotate around the resin shaft formed by the protrusion 234.

By this arrangement, both gears 46 are driven in opposite directions by the crown gear 236 regardless of the rotational direction of the output gear 52 of the motor 48. The allowable amount of rotation of the support block 242 is limited between the two maneuvering positions shown in FIGS. 12 and 14 by the stop face 243 on the frame 32, which stop faces 243 as shown. The pivoting motion of the support block 242 above the first and second steering limits is adapted.

The front wheels 36 for driving and manipulating the toy car in this embodiment of the present invention have a well-known one-way clutch located in the hub 248 in a known manner so that each drive gear 46 and optional Drive engagement is performed. These clutches may be conventional spherical overrunning clutches positioned opposing in the hub, wherein one of the front wheels 36 will be driven forward regardless of the direction of rotation of the crown gear 236.

For example, when the output gear 52 of the motor 48 is rotated in the position shown in FIG. 12 to drive the crown gear 236 clockwise in the same direction as the arrow X, the right drive wheel 36 Will be driven forward, with the one-way clutch included in the hub 248 of the left drive wheel 36 not allowing power to be transmitted from the gear 46 connected to the drive wheel 36. This left driving wheel 36 will not be driven. Thus, even if the gear 46 connected to the left drive wheel is rotated rearward by the crown gear 236, the left wheel 36 will be essentially freewheeling wheel. However, due to the rotational direction of the crown gear 236 and thus the force exerted on the gear 46, the support block 242 on which the gear 46 is rotatably mounted is caused to rotate counterclockwise so that the front wheels are turned to the left. Will be inclined, and if the car was in the outer lane of the track shown in FIG. 1 it would move from the outer lane towards the inner lane and enter the inner track 20.

On the contrary, when the polarity of the current given to the motor 48 is changed so that the crown gear 236 is driven clockwise in the same direction as the arrow Y in FIG. 14, the left drive wheel (i.e., the front wheel) While 36 is driven through the clutch contained in its hub 248, the one-way clutch included in the hub 248 of the right drive wheel 36 transmits the rotational force from the gear 46 to this drive wheel. This right drive wheel 36 will be free to rotate because it does not allow.

In addition, because of the direction of rotation of the crown gear 236 that exerts a coupling force on the support block 242, this support block will rotate clockwise around the axis formed by the protrusion 234 and thus tilt the front wheels to the right. The car 230 will move to the right during the race. In other words, if the polarity of the current applied to the vehicle when the vehicle was in the inner lane was changed and the crown gear 236 was rotated in the direction shown in Fig. 14, the vehicle would move from the inner lane to the outer lane.

Incidentally, in the embodiment of FIG. 14, although the front wheel mounting movable plate corresponding to the adjustment plate 202 in the previous embodiment is not shown, the support block 242 is such a pivotable mounting plate 202. The mounting plate serves to drive the wheels straight after the vehicle changes lanes and hits one side wall of the track.

As described above, according to the present invention, while enjoying a race car by a toy car having a relatively simple structure, each car can be freely changed and enjoyed freely, moving from one track to the other track or moving to another car or an unmanned vehicle. It is possible to overtake a vehicle, and there is an advantage of not having to use a complicated mechanism such as a conventional solenoid bumper or a steering device. Furthermore, since the lane can be changed only by changing the polarity of the current, it is possible to prevent the decrease in speed caused by the lane change caused by the conventional power cut.
