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.

This conventional automobile game zone is limited in interest since only speed control is possible, and thus, there have been many attempts to allow a car to actually move from one lane to another without being limited to the guide groove. In these attempts, a solenoid-operated bumper has been used to mechanically push the vehicle towards the other lane to change lanes. 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 no current loss because there is no interruption of the current, but a large number of rotating parts are required in the control device, there was a problem in wear and maintenance.

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

SUMMARY OF THE INVENTION An object of the present invention is to overcome the drawbacks of the conventional toy vehicle game field, and to provide a toy vehicle game field which can rotate the toy car 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 having a drive transmission device having a relatively simple structure that can change the lane of the vehicle in response to the polarity of the current supplied to the automobile motor.

It is a fourth object of the present invention to provide a toy vehicle having a relatively simple transmission, which can selectively drive any one of the rear wheels of the vehicle in response to the polarity of the current supplied to the automobile motor.

It is a fifth object of the present invention to provide a toy vehicle of the above-described characteristics which is relatively simple in structure and can withstand long-term use.

Another object of the present invention is to provide a toy car and a control apparatus thereof which can be manufactured relatively simply and inexpensively.

According to the present invention, there is provided a toy car for a toy car game ball using one or more toy cars. This toy car is provided with a toy car 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. The drive transmission is installed in the frame and connects the output of the electric motor to the drive wheels. A drive transmission according to an embodiment of the present invention has a spur gear installed on a motor, an output side shaft, and an idler support frame rotatably mounted on the shaft. On this idler support frame an idler gear is rotatably mounted in engagement with the spur gear, so that the support frame and the idler gear move between the first and second positions in accordance with the rotational direction of the drive motor. This drives the Han Chinese wheel of the drive wheel. 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.

Power to the motor motor is made by electrical contact strips located in the lanes of the motor track. According to such a power supply device, not only the competitor can individually control the speed of the vehicle but also change the lane of the vehicle by changing the polarity of the current supplied to the motor. 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 of the lanes and to properly position 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 on which a large number of automobiles can travel.

In the illustrated embodiment of the present invention, there are cars 24 and 26 that are controlled by a player, and these cars have the same structure except for the arrangement of current collectors (which will be described later). 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, and the drive motor is the same as 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.

Each rear wheel 40, ie drive wheel, in the embodiment of the invention as shown is of plastic casting or cast metal. Inside the crown gear 46 is integrally arranged, through which the rotational force is transmitted to the wheel. In one embodiment, these wheels 40 have hubs formed of die-cast metal so that crown gears 46 are integrally installed thereon, and annular removable treads of rubber or the like are known on the hubs. Is fitted in a way.

The driving force of the toy car is supplied from a direct current motor attached to the frame 32. This motor has a structure in which the output shaft 50 is connected to the rotor as a known direct current motor. 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).

In the embodiment of the invention shown in FIGS. 2 and 4-6, the transmission 56 has an approximately U-shaped idler gear support frame 58 mounted freely rotating on the drive shaft 50. The both side corner portions 60 of the support frame 58 are located on both sides of the spur gear 52 and extend substantially radially from the drive shaft 50. A shaft 62 is rotatably mounted on the free end of each of the corner portions 60, and an idler gear 64 is fixed on the shaft 62. The idler gear is engaged with the spur gear 52 to be driven continuously, and can also be selectively engaged with the crown gear 46 (see also FIG. 5). When the motor 48 is operated in such an arrangement, the force exerted on the idler support frame according to the polarity of the current supplied to the motor 48 and by the gears 52 and 64 being engaged with each other. As a result, this support frame is rotated clockwise or counterclockwise as shown in FIG. That is, the gears 52 and 64 will rotate continuously by the operation of the motor 48, and the support frames 58 and 60 are mounted so as to rotate freely on the shaft 50. The force generated by the engagement of, 64 is to rotate this support frame 58, 60 in the same direction as the gear 52. Thus, whether the gear 52 rotates clockwise or counterclockwise, the support frames 58 and 60 are driven in the same direction. As a result, if the gear 52 rotates clockwise as in the direction of arrow X, as shown in FIG. 5, the gear 64 is counterclockwise and the support frames 58, 60 are clockwise. Drive the wheels by engaging them (see solid line in Figure 5). Since the gear 64 and the support frames 58 and 60 are positioned to engage the gear 46 in front of the axle 42, the wheels 40 are driven in the forward direction.

In the game zone shown in FIG. 1, when the driving force due to the polarity of the current applied to the motor 48 is transmitted to the left rear wheel 40 when the vehicle is in the inside lane, it is shown as a dotted line in FIG. As in the case of the vehicle 26, the child door moves from the inner lane 20 to the outer lane 22. At this time, the front part of the vehicle comes into contact with the outer wall 14 of the track, and if the left wheel is continuously driven, the vehicle travels the outer lane 22 along the outer wall 14.

On the contrary, when the polarity of the current supplied to the motor 48 is changed, the support frames 58 and 60 are transferred counterclockwise to the position indicated by the dotted line in FIG. This causes the gear 64 to rotate in the opposite direction and to be engaged with the gear 46 on the right drive wheel 40 (i.e., the lower wheel 40 of FIG. 6), so that only the right wheel is driven and the left wheel is free. Will rotate.

As such, when only the right wheel is driven, the vehicle will be forced to bend to the left, and thus, the vehicle will be moved from the outer lane 22 to the inner lane 20 as in the case of the automobile 26 indicated by a dotted line in FIG. . When the front of the vehicle hits the inner wall 16, the vehicle continues to travel the inner lane 20 along the inner wall 16. At this time, since the gear 64 is located in front of the rotation shaft of the right wheel 40, it is noted that the vehicle always runs in the forward direction irrespective of the rotation direction of the output element of the motor, that is, the spur gear 52. I hope.

Of course, when the automobile travels at a high speed on the curved portion of the track in the inner lane, it tends to be pushed out to the outer lane by centrifugal force.

As clearly shown in FIG. 2, the inverted u-shaped arms 53 are integrally fixed to the vehicle frame 32, and the free end 55 of the arm 53 has a wheel shaft as described above. 42) is firmly or rotatably mounted. These arms are located inside the gear 46 (see also FIG. 5A), and a space for engaging the gear 64 with the gear 46 is formed in the central curved portion thereof. When the gear 46 engages one of the gears 64, the rotation of the support frames 58, 60 is typically stopped, but the upper end 57 of the curved portions of these arms defines the position of the support frames 58, 60. It serves as a limit position on both sides for building.

Alternatively, the size of the support frame may be determined so that the support frames 58 and 60 can pass through the upper end with the rotation of the arm 53 without touching the upper end 57. In such a case, the stop means 59 can be provided on the inner side surface of the arm 53 as indicated by the dotted line in FIG.

In another embodiment of the present invention shown in Figure 5a uses a slightly different type of power transmission device, but at this time also to selectively drive only the right or left drive wheels according to the polarity of the electric current supplied to the automobile motor It is the same. In this embodiment, the toy car comprises an approximately triangular idler support frame 60 'when it is rotatably mounted on the motor shaft 50 adjacent to the spur gear 52. On this support frame 60 ', two idler gears 64' rotatably mounted at the same time as long as current is supplied to the motor 48 are rotatably mounted. Since these gears 64 'are laterally spaced apart from each other, only one gear 64' is engaged with the gear 46 of the wheel whenever power is supplied to the motor 48. By this arrangement, the support frame 60 'is rotated left or right in accordance with the rotation direction of the spur gear 52 to drive one of the rear wheels of the vehicle. This arrangement results in a somewhat shorter reaction time due to the switching to drive one of the rear wheels. As described for the above embodiment, the operator can control which driving wheel of the vehicle is powered by controlling the polarity of the motor, so that the vehicle is used in the game zone of FIG. 1 in the same manner as described above. To make that lane change.

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 of the present invention, 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, which of the two rear wheels is driven depends on the polarity of the current supplied to the motor of the vehicle, thereby determining the lane in which the vehicle will travel.

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.

As described above, the shock absorbing shear 38 is provided in the toy car of the present invention. These shock-absorbing front ends 38 preferably have the structure and function as described in the applicant's prior application specification, and thus, detailed description thereof will be omitted.

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.
