Publication number: 20020068502Abstract: A ground-engaging toy vehicle powered by water flowing from a garden hose. The hose is connected to a stationary portion of a stake that serves as a center of revolution for the tethered vehicle. The water leaves the stationary portion of the stake into a rotary portion, traversing through a plastic tube that serves as a tether into an impeller housing. The impeller is attached to the drive shaft that is, in turn, attached through a reduction gear box and a series of pulleys and drive belt to the four wheels of the vehicle. After the water stream of the hose has partially exhausted its energy driving the wheels, it is discharged from the impeller housing to a plurality of fluid exhaust ports to provide one or more water sprays for kids to run through. In the preferred embodiment, the toy vehicle is configured as a fire truck.Type: ApplicationFiled: December 4, 2000Publication date: June 6, 2002Inventor: Charles D. Kownacki
