The first and second power transmission means 40a, 40b are running toys 1
Is formed so as to mesh with the first and second power transmission means 40a and 40b only when the rotation of the first power transmission means is performed in a direction in which the first power transmission means advances forward.

Further, the first and second power transmission means 40a,
Reference numerals 40b are provided on the left and right sides of the bearing member 23, respectively. The first and second gears 39a and 39b mesh with the crown gear 37 that rotates about the lower central shaft 47 of the bearing member 23. ing. Therefore, the crown gear 37
Rotates in a clockwise direction (CW) as viewed from above the chassis 3, the first power transmission means 40 a rotates counterclockwise as viewed from the bearing member 23, and the internal teeth 75 a in the right drive wheel 25.
And the claw members 67a, 67a mesh with each other, and rotate the right driving wheel 25 in a direction in which the traveling toy 1 moves forward.

On the other hand, when the crown gear 37 moves clockwise (C
When rotated to W), the second power transmission means 40b rotates counterclockwise when viewed from the bearing member 23. In this case, the pawl member 67 is formed inside the left driving wheel 27 with respect to the internal teeth 75b.
The b and 67b do not engage with each other and run idle, so that the driving force to the left driving wheel 27 is not transmitted. Therefore, in the above case, only the right driving wheel 25 obtains the driving force and the traveling toy 1 rotates in the forward traveling direction, and the other left driving wheel 27 connected by the same driving shaft 29 also moves.
Rotate in the direction to move forward. (Fig. 5)

In this case, with the rotation of the crown gear 37 in the clockwise direction (CW), a force for rotating the bearing member 23 itself in the same direction acts, and as a result, the right and left driving wheels 2
Since the traveling toys 1 and 5 are directed in a direction in which the traveling toy 1 travels straight, the traveling toy 1 travels forward while traveling straight. The rotation range of the bearing member 23 is limited by the protruding pin 49 that moves in the guide hole 53 as described above, and the protruding pin 49 is connected to one end 53 a of the guide hole 53.
Is adjusted so as to be at a position where the traveling toy 1 goes straight (that is, a position where the bearing member 23 is substantially perpendicular to the straight running direction). The projecting pin 49 is moved in the opposite direction (the guide hole 5) by the torsion spring 59 as described above.
3) (in the direction of the other end 53b).
The bearing member 23 is directed in the straight traveling direction against the urging force of the torsion spring 59.

Next, the case where the crown gear 37 rotates counterclockwise (CCW) when viewed from above the chassis 3 will be described. In this case, the first power transmission means 40a rotates clockwise as viewed from the bearing member 23, and the internal teeth 75a and the claw members 67a, 67a idle inside the right drive wheel 25 without meshing. Therefore, no driving force is transmitted to the right driving wheel 25. On the other hand, the crown gear 37 moves counterclockwise (CCW).
, The second power transmission means 40b rotates clockwise as viewed from the bearing member 23. In this case, the pawl members 67b, 67b mesh with the internal teeth 75b inside the driving wheel, and rotate the left driving wheel 27 in a direction in which the traveling toy 1 moves forward. Therefore, in the above case, the left driving wheel 27
Rotates in the forward direction of the traveling toy 1 so that the same drive shaft 2
The right driving wheel 25 at the other end connected by 9 also rotates in the forward direction of the traveling toy 1.

In this case, with the rotation of the crown gear 37 in the counterclockwise direction (CCW), a force for rotating the bearing member 23 in the same direction acts, and as a result, the left and right drive wheels 2
5 and 27 are directed to the direction in which the traveling toy 1 turns to the left, and the traveling toy 1 moves forward while turning left (FIG. 6). The rotation in the counterclockwise direction (CCW)
This is the rotation direction of the crown gear 37 that rotates the first gear 39a in a direction in which the first power transmission means 40a does not transmit power. The rotation range of the bearing member 23 is limited by the protruding pin 49 that moves in the guide hole 53 in the same manner as described above, and the bearing member 23 is moved from a direction substantially perpendicular to the straight traveling direction.
In the rotation direction of the crown gear 37 that rotates the first gear 39a in a direction in which the first power transmission means 40a does not transmit power, until the protruding pin 49 contacts the other end 53b in the guide hole 53. The traveling toy 1 turns to the left. The projecting pin 49 of the bearing member 23 is provided with a torsion spring (elastic member) 59 as described above.
Of the crown gear 37 that rotates the first gear 39a in a direction in which the first power transmission means 40a does not transmit power, thereby switching the rotation direction of the crown gear 37. Is performed, the rotation of the bearing member 23 from the straight traveling direction to the left turning direction is performed smoothly.

Next, a case in which the drive motor 7 is stopped while the traveling toy 1 is traveling will be described. When the rotation of the drive motor 7 is stopped, the crown gear 37
Rotation stops. In this case, when the traveling toy 1 is traveling straight, the rotation of the first power transmission means 40a is stopped, and the state in which the right drive wheel 25 is idling with respect to the first power transmission means 40a. Become. Then, in this state, the traveling toy 1 travels by inertia. Similarly, the left driving wheel 27 is also idle with respect to the second power transmission means 40b. Further, when the rotation of the crown gear 37 is stopped, a force transmitted through the drive shaft 29 to the rotation (the straight traveling direction) of the bearing member 23 is not generated. Disappear and the torsion spring 59 causes the bearing member 23 to turn to the left turning direction. That is, when the drive motor 7 is stopped, the right and left drive wheels 25 and 27 face the left turning direction with the left turning of the bearing member 23, and the traveling toy 1 proceeds by inertia in the left turning direction. Becomes
Note that, even when the drive motor 7 is stopped while the traveling toy 1 is turning left, the traveling toy 1 proceeds by inertia in the left turning direction as described above.

As the simplest form of remote control, there is control such as "rotation of drive motor" accompanying signal transmission and "stop of rotation of drive motor" following stop of signal transmission. For example, a remote control device of this type using a radio signal has a simple circuit and the like, and can be configured at very low cost.
The direction changing device 5 according to the present application can also control the traveling of the traveling toy 1 by such remote control. In other words, by performing straight traveling to "rotation of the drive motor" accompanying the signal transmission and performing inertial running while turning by "stopping the rotation of the drive motor" due to the stop of signal transmission,
The traveling of the traveling toy 1 can be controlled. As described above, by employing the remote control method described above and the direction changing device 5 according to the present application, a small and inexpensive traveling toy using the remote control method can be provided.

The first and second power transmission means 40
Reference numerals a and 40b rotate with the rotation of the crown gear 37. The crown gear 37 itself rotates with the rotation of the spur gear 33 rotated by the drive motor 7 as described above. I have. Further, the drive motor 7 is fixed by being sandwiched between the chassis 3 and the frame member 61, and the pinion 35 positioned between the drive pinion 31 of the drive motor 7 and the crown gear 37 is moved. The spur gear 33 integrally provided is also supported by a plate-like bearing plate erected on the chassis 3 and a bearing plate hanging down from the frame member 61.

The undercarriage 3 is further provided with a battery or a capacitor serving as a power supply 75,
A switch 77 for performing FF is provided. The switch button 79 of the switch 77 is provided so as to protrude from a small hole 81 formed in the chassis 3.
The power supply 75 can be turned on / off. The frame member 61 has a plurality of predetermined mounting holes, and is fixed by screws 83 to a mounting boss 82 of the chassis 3 provided at a position facing the mounting hole. The printed wiring board 11 is attached to the frame member 61, and an antenna 85 is attached to a mounting boss 83 at the rear of the chassis 3 by screws 87 and nuts 89. Although a detailed description is omitted, the traveling toy according to the present embodiment employs a simple remote control means for rotating the drive motor 7 forward or backward by receiving radio waves.

As described above, the direction changing device according to the present invention is directed straight or left (or right) while running the traveling toy 1 by simple control such as forward rotation, reverse rotation, and stop of the drive motor 7. And its traveling direction can be changed. In addition, since the traveling and the direction change of the traveling toy are controlled by a single drive motor, it is not necessary to provide a driving mechanism for traveling and for the direction conversion, respectively. Can also be miniaturized. Further, when the traveling direction is changed, it is not necessary to perform an operation of retreating the traveling toy itself as in the related art, so that the direction can be changed while traveling. As a result, it is possible to provide a very small traveling toy that is a traveling toy that can run at a high speed on a race course like a real car.

In order to control the operation of the traveling toy 1 by a radio signal such as an infrared ray or a radio wave, the drive motor 7 is stopped when there is no transmission (no signal), and the control signal is a normal rotation of the drive motor. It is sufficient to have a function of receiving only the instruction signal and the reverse rotation instruction signal of the drive motor, so that a remote control signal receiving circuit and a separately provided transmitter (controller, not shown) can be formed extremely easily.

Next, another embodiment according to the present invention will be described. In the above-described embodiment, the power transmission means is provided for each of the left and right drive wheels 25 and 29, and transmits power in a predetermined rotation direction. In the other embodiment, it is possible to provide a structure in which the claw members 67b, 67b provided in the second power transmission means 40b for the left driving wheel in the above embodiment are not provided. That is, the second power transmission means 40b
The transmission of the power to the left driving wheel 29 is not performed.

The characteristic point of the above structure will be described. When the crown gear 37 rotates clockwise (CW),
As in the case of the above embodiment, the traveling toy 1 is driven so as to go straight. On the other hand, when the crown gear 37 is rotated in the counterclockwise direction (CCW), the bearing member 23 moves in the same direction, that is, the bearing member 23 moves straight by the rotation force of the crown gear 37 and the action of the torsion spring 59. From the direction substantially perpendicular to the direction, the first power transmission means 40a rotates toward the rotation direction of the crown gear 37 for rotating the first gear 39a in a direction in which power is not transmitted, and the driving wheels 25, 27 turns to the left turning direction. At this time, since the driving force is not acting on the left and right driving wheels 25 and 29, the traveling toy 1 advances by inertia in the traveling direction.

That is, when the traveling direction of the traveling toy 1 is switched from straight traveling to left turning (when the rotation direction of the crown gear 37 is switched from clockwise (CW) to counterclockwise (CCW)), the traveling toy 1 It proceeds by inertia while turning left and stops when it travels a predetermined distance. When the traveling direction of the traveling toy 1 is switched from left turning to straight traveling (when the crown gear 37 is rotated clockwise (CW)), straight traveling starts again. Therefore, the traveling toy 1 can be caused to travel in the intended direction by alternately controlling “straight ahead with driving” and “turn left without driving”.
