  • Patent number: 4652247
    Abstract: This toy propels itself along the surface of a pool of water or along an extremely steep, irregular nonwater surface. A battery powers a motor, which drives the vehicle's four wheels and a steerable water jet. The wheels carry pronounced peripheral cleats for propulsion along both a water surface and a very steep, irregular nonwater surface. The hollow wheels, several times overscale, contribute significantly to overall buoyancy. The water-jet impeller aids propulsion along a water surface and can be rotated horizontally to direct the vehicle in circles of variable diameter. The motor shaft is aligned with the direction of vehicle travel and extends both forwardly and rearwardly from the motor to drive a symmetrical geartrain for nonwater-surface propulsion: fixed on each shaft end is a pinion that drives a spur gear, which in turn drives a worm, that in its turn drives a worm gear keyed to an axle. The worm gear drives the axle, which drives the wheels and tires.

  • Patent number: 4582171
    Abstract: A unique drive mechanism for a toy vehicle is disclosed which can be selectively enabled to cause the toy to come to an abrupt halt after a powered run, and which can cause the toy to realistically imitate a "spin out" of a full scale vehicle. The drive train includes a first gear directly rotated by a coiled spring, a second gear coupled in driving engagement with the vehicle's wheels, and a third gear shiftable between an engaged position coupling the first and second gears, and a cleared position wherein the second gear can rotate independently of the first gear. The third gear can be locked in its engaged position by a pivotal, gravity biased locking mechanism. The selective, locked engagement of the first, second and third gears causes the vehicle to come to an abrupt halt after the coil spring has fully unwound at the completion of a powered run.

  • 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: 4488375
    Abstract: A toy motor car comprises a body having a bottom cover secured thereto by means of screws and a frame on which the body is pivotally mounted. Back wheels of the car are rotatably mounted to the frame and are adapted to be driven in rotation by a battery powered motor housed in a gear box mounted on the frame. The motor also effects rotation of a pinion and an eccentric cam. A clutch is provided in the gear box for changing the direction of rotation of the back wheels at predetermined intervals and, when the car is travelling in a first direction, the cam engages a cam follower which is pivotal with respect to the frame to effect rocking of the body relative to the frame. When the direction of rotation of the back wheels changes, the cam is disengaged from the cam follower and the pinion engages a rack of a lever thereby turning front wheels of the car.
