  • Patent number: 4596534
    Abstract: A multiple wheeled toy car featuring a remotely controlled front wheel steering and a single powered, middle, rear wheel for propulsion. Two other rear wheels flank the powered wheel. The flank rear wheels are each mounted upon a freely moveable road wheel arm with a limiter to limit upward travel of the arm. These flank wheels contact the surface and tend to resist lateral displacement of the car's rear end when the car has been placed into a hard turn.

  • Patent number: 4571213
    Abstract: A direction-converting device for a toy car is disclosed, in which the toy car is provided with an electromagnet having an exciting iron core with its opposite sides being energizable to different polarities and a magnet having opposite end faces with different polarities, in which one core portion of the electromagnet at its free end has a width equal to or larger than a width of the opposed end of the magnet, and in which the electromagnet or the magnet is fixed to one end of a controlling element which in turn is arranged at a middle portion of a steering element. The one core portion of the electromagnet may be divided into two portions, between which is arranged another magnet.Thus, the device ensures a neutral position of the steering element reliably in the deenergized state of the electromagnet.

  • Patent number: 4570092
    Abstract: A driving apparatus for use in a movable toy is disclosed, and includes a mobile body, an immobile body, a plurality of permanent magnets fixed to the mobile or immobile body, at least one electromagnet fixed to the other body so as to co-operate with the permanent magnets, a pair of contactless switches, and a circuit for exciting the electromagnet winding depending on the state of energization of the contactless switches and the position of the permanent magnets relative to the electromagnet. The driving apparatus is capable of not only rotary movement but also straight movement.

  • Patent number: 4471566
    Abstract: A direction converting device for a toy car has an electromagnet energizable to a desired polarity upon change of a running direction and at least a pair of magnet elements arranged oppositely thereto and maintained at different polarities from each other. The electromagnet or the pair of magnets may be secured to a controlling element swingably in a horizontal plane, while the controlling element is engaged with a steering plate articulatingly connected to wheels.

  • Patent number: 4112615
    Abstract: A wireless trans-ceiver control system for a motor driven toy vehicle having a transmitter for generating a predetermined carrier of selected high frequency, and a receiving unit including a super regenerative detection circuit for receiving the high frequency carrier and normally producing an amplifiable noise signal which is attenuated by the high frequency carrier. A relay switch, for reversing the power to the electrical motor driving the toy vehicle, is energized by the amplified noise signal to retain the switch in one position and release the relay to a second position when the high frequency carrier from the transmitter attenuates said noise signal. In a modification, a gearing train drives the vehicle in one direction in one position of the switch but drives the vehicle in the same direction and also turns the wheels for turning the vehicle in the second position of the switch.

  • Patent number: 4080602
    Abstract: This invention is concerned with a remote control trans-receiver system in which a transmitter having a single channel is used for transmitting information to a remote receiver adapted to receive the information for controlling the movements of a toy vehicle. The single transmitting channel includes means to provide modulated information onto a carrier wave for controlling the forward, rightward and leftward movements of the toy vehicle, and a switching device for preventing the transmission to the receiver of any modulating information to permit stopping of the forward movement of the vehicle and to enable, when desired, reverse movement of the toy vehicle. The receiver detects the modulated information, when present, for effecting forward, rightward or leftward movement of the toy vehicle. The receiver further includes a switching device which responds to the absence of a modulating signal on the carrier to stop and then reverse the direction of travel of the toy vehicle.
