  • Patent number: 4655724
    Abstract: A steering and drive system for toy vehicles is disclosed. Independent gear trains for wheels on opposite sides of the toy vehicle are utilized in combination with a single reversible motor to either rotate all wheels in the same direction to move the vehicle in a straight line or, by reversing the direction of the motor, to rotate wheels on opposite sides of the vehicle in opposite directions causing the vehicle to turn. Wheels on one side of the vehicle are connected to a main gear and the direction of rotation of such wheels is completely dependent upon the polarity of an electric power source applied to the motor. Wheels on the opposite side of the vehicle are indirectly connected to the main gear by a movable control gear which is urged to engage either an auxiliary gear or a second side drive gear so that the wheels rotate in only a single direction regardless of the direction of the motor.

  • Patent number: 4573943
    Abstract: A toy vehicle propelled by a bi-directional, miniature d-c motor, coupled by a clutch through a gear train to a wheel axle. A manually-operated shift stick mechanism is operatively linked both to the clutch and to a polarity-reversing switch interposed between the motor and a battery. The arrangement is such that when the stick is in neutral, the battery is disconnected and the clutch is disengaged, whereby the vehicle is then free rolling. When the stick is put in its forward position, the clutch is engaged to couple the motor to the gear train and the switch is operated to apply voltage to the motor in a polarity causing the vehicle to travel in the forward direction. When the stick is put in its reverse position, the clutch is again engaged and the switch is operated to apply voltage to the motor in the reverse polarity, causing the vehicle to travel in the opposite direction.

  • Patent number: 4553947
    Abstract: A shift mechanism for a motorized toy includes a shift lever which is mounted on the toy so as to be able to move back and forth along an X axis and back and forth along a Y axis. The toy includes an electric motor and electric power supply for powering the same. A gear train connects the electric motor to an output shaft. A shift mechanism is connected between the shift lever such that movement of the shift lever along one of the X or Y axes shifts certain of the gears in the gear train to control the speed of the output of the output shaft. Movement along the other of the axes of the shift lever controls an electric switch which governs both the polarity of the current supplied to the motor to provide for both forward and reverse rotation of the output shaft as well as to break the circuit between the power supply in order to start and stop the toy.

  • Patent number: 4545776
    Abstract: A steering mechanism for self-powered vehicles and vehicles employing this mechanism are disclosed. The steering mechanism is characterized by a yoke pivotably attached to the vehicle frame which carries one of the vehicle's axles. A crown gear is provided on the axle which engages a spur gear mounted on the yoke in a position substantially perpendicular to the crown gear. The spur gear is connected through a drive train to a reversible motor. Stops are provided on the frame or yoke which hold the axle substantially parallel to the vehicle's other axle when the motor is turning in a given direction. Then the axle is positioned so that the vehicle will travel in a straight line. When the motor is reversed the stops will allow the yoke and attached axle to pivot to a postion where the axles are no longer parallel and the vehicle will turn.
