Description

[Detailed Description of the Invention] "Field of Industrial Application" The present invention relates to a remote-controlled running toy that is connected to a remote control device that is operated at hand via a connecting line, and is particularly concerned with cases where the connecting line is twisted during running operation or the running toy is This provides a structure to prevent entanglement with the main body.

``Prior Art'' Conventionally, the above-mentioned remote-controlled running toys have been constructed by installing a driving motor in the main body of the running toy such as a toy car, and connecting the motor with a connection line that connects to a remote control device at hand. By operating a changeover switch of the control device, the direction of rotation of the motor is changed over the connection line, thereby controlling the direction of movement of the traveling toy.

``Problems to be solved by the invention'' However, in the conventional remote-controlled traveling toy mentioned above, a connecting wire is integrally connected to the motor provided in the main body of the traveling toy, so it is difficult to operate the traveling toy. Sometimes, unless the main body of the moving toy and the remote control device at hand are maintained at a constant distance and direction, the connecting wires between them may be twisted, or the connecting wires may get tangled with the main body of the moving toy. In addition, there have been other drawbacks such as malfunctions in the connecting wires, such as inability to operate or breakage of the connecting wires.

"Means for Solving the Problems" The present invention eliminates the drawbacks of the conventional type described above, and includes forming a bearing part on the upper part of the main body of the traveling toy.
A motor mounting base with a rotating shaft protruding in a substantially vertical direction is rotatably mounted on the coaxial receiving part, and a drive device is linked to the rotating shaft of the motor via a reduction gear device inside the main body. It is what it is.

"Function" In the above-described configuration, by forming a bearing part on the upper part of the main body of the traveling toy, the mounting base of the motor, which has a rotating shaft protruding approximately vertically on the main body, can be rotatably mounted. The rotary shaft of the motor is connected to the connection line of the remote control device at hand by linking the drive device in the main body via a reduction gear device, and is mechanically linked. Power can be transmitted into the main body no matter what direction the main body faces with respect to the motor, and twisting of the connection wire can be prevented.

``Example'' The present invention will be explained with reference to an example shown in the figure below. 1 is a main body of a running toy such as a toy car, and the upper part of the main body 1 is equipped with a bearing etc. that supports a substantially vertical rotation axis. A bearing part 2 is formed, and a mounting base 5 is rotatably mounted on the coaxial bearing part 2, and a bracket for a motor 4 having a rotating shaft 3 protruding therefrom in a substantially vertical direction is mounted thereon. In addition, a pinion 31 is installed on the rotating shaft 3 of the motor 4, and a frame body equipped with a plurality of bearings is formed in the main body near the pinion 31, and the frame body has spur gears 6 each equipped with a pinion.
1, 62, 63, a crown gear 64, etc.
1 constitutes a drive unit linked to the pinion 3.
1 is meshed with the spur gear 61 of the reduction gear device 6. On the other hand, the mounting base 5 of the motor 4 has an appropriate length located at least outside the main body 1, as shown in FIG. A holding member 10 of a is provided in a protruding manner. Further, a battery for power supply is provided in the remote control device 8, and a plurality of push button switches 81, 82, etc. are connected to the battery to connect to the connection line 9 and switch the connection polarity of the battery to the motor 4. be.

With the above configuration, when the remote control device 8 is held in hand and the push button switch 81 is operated, battery voltage is applied to the motor 4 via the connection line 9, and the motor 4 rotates in the normal direction. The main body 1 of the traveling toy can be moved forward by driving the drive wheels 7 via a reduction gear device 6 connected to the rotating shaft 3. Similarly, when the push button switch 82 is operated, the motor 4 is reversely rotated, and the main body 1 of the traveling toy can be similarly moved backward. In this case, it is possible to add a steering means to the main body 1 so as to change the direction in a fixed direction only when moving backward, and the push button switch 8
By moving the main body 1 forward and backward based on operations 1 and 82, it can be steered in any direction.

When the traveling toy is driven by operating the remote control device 8, the motor 4 side is always connected to the remote control device 8 at hand via the connection line 9 and is mechanically linked; By rotatably mounting the mounting base 5 on the main body 1, the connecting wire 9 will not be twisted no matter what direction the main body 1 faces, and the rotating shaft 3 of the motor 4 can be rotated. A reduction gear device 6 connected to this as the center
Power can always be transmitted to the drive wheels 7 via the drive wheels 7. Furthermore, by protruding the holding member 10 from the mounting base 5, it is possible to configure at least the lead-out portion of the connecting wire 9 to be supported outside the end of the main body 1. No matter what direction the main body 1 side faces, the connecting wire 9 will not be caught on the main body 1.

``Effect of the invention'' As described above, in configuring a remote-controlled running toy that is connected to a remote control device that is operated at hand via a connecting line, the toy moves around the rotating shaft of the motor that is connected to the connecting line side without any hindrance to power transmission. Since the direction of the main body side of the toy can be freely changed, it is possible to prevent the connecting wire from twisting or becoming entangled with the main body of the moving toy during running operation. This makes it possible to prevent accidents that occur in the conventional type, such as loss of control or disconnection of the connection line due to a problem with the connection line during running.
