Abstract

PROBLEM TO BE SOLVED: To provide a radio-controlled toy employing a spiral spring as a power source and available without electric power supply such as a dry battery.SOLUTION: This radio-controlled toy has a spiral spring 2 that accumulates power by being manually wound to rotate a power generator 5 by the accumulated power when the spiral spring 2 is released to generate electric power. A forward/backward switching servo 12 and a steering servo 13 are driven by power output from a rechargeable battery 6 charged with the electric power to move an automobile 100. The power source of a radio control receiver 8 also employs the rechargeable battery 6 as the electric power supply.

  The present invention charges the charger using the accumulated power when the mainspring stored by hand winding is released, and uses this electric power as a power source for the running and radio control equipment. Related to toys.

  2. Description of the Related Art Toys that can be driven by the stored power of a spring and toys that run by driving a motor using a dry battery or a wireless communication circuit that uses a battery as a power source can be remotely operated.

  However, in the case of a toy that runs on a mainspring, the distance traveled is short, and the child's interest is halved.

  On the other hand, the battery driven type cannot run when the dry battery runs out, and it is expensive to purchase the dry battery, and there is also a problem of waste pollution.

  In the case of a toy that can be operated remotely, a dry battery or the like for driving a control circuit for the remote operation is required.

  For example, in Japanese Utility Model Laid-Open No. 7-494, a rechargeable secondary battery is mounted on the traveling toy side, and a separate manual handle rotating generator for charging the secondary battery is provided. A toy that does not use a dry battery that charges the generated battery to a secondary battery via a cable has been introduced.

  However, in the case of this toy, since the toy and the generator are separate bodies, it is necessary to connect the cable to the toy with a connector and charge it one by one, and when this is done, it is necessary to remove the connector, which is troublesome .

  Japanese Utility Model Registration No. 3106592 discloses a direct current that is driven by a battery that can be charged and supplies auxiliary power to the load, and a restoring force that causes the spring to which the rotational force is applied to return to the state before the rotational force is applied. A DC motor that generates power and supplies main power to the load, a voltage comparator that compares auxiliary power from the battery and main power obtained by the DC motor, and combines the auxiliary power and the main power. When the DC motor is in a state of generating surplus power from the comparison result of the voltage regulator that supplies appropriate power to the load and the comparator, the battery is charged with the surplus power, and the voltage regulator In addition, a spring type power supply device has been introduced that includes arithmetic processing means for supplying the appropriate power to the load.

  However, this spring type power supply device is complicated and expensive, and a toy having a simplified content is desired.

  Japanese Patent Application Laid-Open No. 2008-113973 provides a transmitter and a receiver that do not need to carry a generator separately from a toy in both the transmitter and the receiver, and a radio-controlled traveling toy. An electromotive force signal generation unit that combines generation and signal generation, a high frequency signal generation unit that generates high frequency signals, and an antenna that radiates high frequencies, and generates signals and electromotive force without using a battery. The receiver is capable of transmitting signals, the receiver includes a driving force generator that generates driving force, an electromotive force generator that converts driving force into electromotive force, a control signal receiver that receives control signals, and a high frequency A toy that has a radiating antenna and that can receive a signal by generating a driving force and an electromotive force without using a battery has been introduced.

  However, this known toy is functionally insufficient to attract children's interests.

  It is an object of the present invention to provide a radio-controlled toy that has a high degree of completion as a toy, can attract children's interest sufficiently, and uses power generated by a spring that does not use any dry batteries as a power source. To do.

  In order to achieve the above object, the invention described in claim 1 is equipped with a spring that is stored by manual winding, and generates electricity by rotating a generator with stored power when the spring is released, The motor can be rotated in the forward or backward direction by a motor that is rotated by the output from the charger charged with the generated electric power, and has a traveling control means for switching the rotational direction of the wheel. An operation control circuit for controlling the control means by receiving a radio signal is mounted.

  According to the present invention, it is possible to provide a toy that can be run or operated without using any dry battery.

  Further, according to the present invention, the mainspring hoisting handle for accumulating the mainspring is attached downward to the roof portion of the toy car and an LED is attached to the knob portion of the handle, and the power source is connected to the LED. Power is supplied only when the car toy is running, and the LED flashes in the image of the flashing light of the emergency vehicle.

  According to the present invention, interest as a toy can be further increased.

Furthermore, the invention according to claim 3 is a vehicle body to which a front wheel capable of controlling the direction is attached and a rear wheel which can be moved forward or backward by a drive servo is attached.
