Toy vehicle having body capable of vertical movement with respect to
chassis
摘要:
A toy vehicle has a body, and attached to the body is a chassis which is movably mounted thereon so as to move vertically up and down relative to the chassis. A motor is located within the vehicle and aside from propelling the vehicle forward over a support surface, the motor additionally drives a mechanism which raises and lowers the body relative to the chassis. When the body is raised relative to the chassis, the vehicle is propelled forward over the support surface by the motor; however when the body is lowered to the chassis, the drive connection between the driving wheel of the vehicle and the support surface is severed, inhibiting forward progress of the vehicle. The vehicle performs the above noted functions in a cyclic manner, repeating one after the other.
