  • Patent number: 4457101
    Abstract: A radio-controlled toy car which can smoothly turn its running direction even when the toy car is running with the front wheels kept lifted from the ground, that is, even during the wheelie motion. The toy car according to the present invention comprises a differential gear mechanism, two drive shafts rotatably connected to the differential gear mechanism, two electromagnets for applying a brake force to each of the two drive shafts, independently, when energized in cooperation with one of two magnetic cylindrical members fixed to the two drive shafts separately, a front wheel and, in particular, an auxiliary rear wheel, in addition to two ordinary rear wheels and two front dummy wheels. Furthermore, since a connecting rod is provided for loosely connecting the two drive shafts, the differential gear mechanism functions reliably.

  • Patent number: 4438589
    Abstract: A moving toy having a front wheel and a rear wheel supported on a body and capable of operating in a normal mode with the front and rear wheels engaging the ground, and in a wheelie mode with the front wheels raised, having a battery in a battery receptacle for providing electric power to operate the toy. The center of gravity of the battery receptacle is located forward of the axle for the rear wheel when the toy is operating in the normal mode and rearward of the rear wheel when the toy is operating in the wheelie mode. The battery receptacle includes a spring biased stopper on a stop lever for engaging grooves on a surface of the vehicle body to retain the battery receptacle in a fore or an aft position, or in intermediate positions therebetween.
