Assignee: Mabuchi Motor Co. Ltd. (Tokyo, JP)
Primary Examiner: Caldwell, Sr.; John W.
Assistant Examiner: Crosland; Donnie L.
Attorney, Agent or Firm:

A radio controlled, battery-operated model toy having an electric motor, a battery device for supplying energy to the electric motor, a radio control receiver, and a servo mechanism operated by the output of the receiver, wherein a voltage responsive automatic circuit breaker which opens the electric circuit of the electric motor in response to a voltage drop in the battery device and holds the circuit in the open stage is provided between the battery device and the electric motor, and a voltage regulator/noise filter is provided between the battery device and the radio control receiver.

DETAILED DESCRIPTION An object of this invention is to provide a radio controlled, battery-operated model toy in which a battery device for driving the model toy is used as a power supply for a radio control receiver to make full use of the reserve power of the battery device.
Another object of this invention is to provide a radio controlled, battery-operated model toy in which a voltage responsive automatic circuit breaker is provided between the battery device and an electric motor for driving the model toy to prevent series-connected batteries, for example Ni-Cd batteries, comprising the battery device from being reverse charged.
Still another object of this invention is to provide a radio controlled, battery-operated model toy in which a voltage regulator noise filter is provided between the battery device and a radio control receiver to eliminate voltage fluctuations and noise in the battery device, thus preventing the unwanted operation of the radio control system.
A further object of this invention is to provide a radio controlled, battery-operated model toy, especially a model toy such as a model ship that requires a certain amount of energy to be safely recovered, in which a current control device is provided in parallel with the switch portion of the voltage responsive automtic cutoff device to supply the electric motor with a sufficient level of current to prevent batteries comprising the battery device from being reverse charged and yet to permit the model toy to be safely recovered.
