ABSTRACT:
BACKGROUND OF THE INVENTION
a. Field of the Invention
The instant invention is directed toward a toy trash truck. More specifically, it relates to a remote-controlled toy trash truck capable of forward motion and realistic operation.
b. Background Art
Toy vehicles are well known. Remotely controlled and radio-remotely controlled toy vehicles are popular in the toy market. Manufacturers of such toys frequently attempt to duplicate well known vehicles. In particular, manufacturers constantly seek innovative ways to simulate reality in toy vehicles to enhance the entertainment value these toys provide.
SUMMARY OF THE INVENTION
It is an object of the disclosed invention to provide an improved remote-controlled toy vehicle. The toy vehicle of the preferred embodiment described below is toy trash truck having a propulsion system, including a plurality of tires, operably affixed to a frame member. There is also a trash-holding bin mounted on the frame member, and a load-lifting arm operably connected to the frame member and capable of lifting items (e.g., actual or simulated trash) for placement into the trash-holding bin. A signal receiver that receives and interprets signals from a remote-control device may be mounted on the frame member.
In another form, the toy trash truck comprises a propulsion system operably affixed to a frame member comprising at least one main longitudinal beam. The propulsion system includes at least one main drive motor having an output shaft, a plurality of tires, and a driveline drivingly connecting the output shaft to at least one driven tire of the plurality of tires. A trash-holding bin, which is mounted on the at least one main longitudinal beam in the preferred embodiment, has a top with a rear edge. The trash-holding bin is capable of moving between a resting position and a dumping position. The trash-holding bin further comprises a purge door and an overhead door, both of which are capable of moving between an open position and a closed position. Further, the overhead door is slidably mounted to the top of the trash-holding bin, and the purge door is hingedly mounted along the rear edge of the top of the trash-holding bin. A pair of U-shaped main dumpster-lifting arms are operably connected to the frame member at a main lift arm pivot pin and are capable of lifting items for placement into the trash-holding bin. A wireless signal receiver that is supported by the frame member receives and interprets signals from a remote-control device, and a battery power supply, which may also be supported by the frame member, is coupled to the wireless signal receiver. A plurality of servo motors are appropriately placed on the toy trash truck to accomplish many functions, including moving the entire toy truck forward and backward, rotating the pair of U-shaped main dumpster-lifting arms about the main lift arm pivot pins, opening the overhead door, opening the purge door, and moving the trash-holding bin between its resting position and its dumping position. Finally, a suspension system supports the truck above the plurality of tires.
