Abstract
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. The toy vehicle includes 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.
Claims43
A toy trash truck comprising
- a propulsion system operably affixed to a frame member, said propulsion system including a plurality of tires;
- a trash-holding bin mounted on said frame member, said trash-holding bin comprising a bottom wall, a top wall, an overhead door selectively covering a trash hatch through said top wall, and a purge door, both of said doors being capable of moving between an open position and a closed position, and further wherein said overhead door is slidably mounted to a top of said trash-holding bin;
- a load-lifting arm operably connected to said frame member and capable of lifting items for placement into said trash-holding bin;
- an elevation system for lifting said trash-holding bin into a raised, dumping configuration and lowering said trash-holding bin into a lowered, loading configuration, said elevation system comprising
- a can-lift actuator arm;
- a can lifting tower affixed to said bottom wall;
- a lift force transfer arm rotatably connected at a first pivot connection to said can-lift actuator arm, and said lift force transfer arm rotatably connected at a second pivot connection to said can lifting tower;
- and
- a central lift-assist cylinder.

A toy trash truck comprising
- a propulsion system operably affixed to a frame member comprising at least one main longitudinal beam, said propulsion system including at least one main drive motor having an output shaft, a plurality of tires, and a driveline drivingly connecting said output shaft to at least one driven tire of said plurality of tires;
- a trash-holding bin having a top wall with a rear edge, said trash-holding bin mounted on said at least one main longitudinal beam, wherein said trash-holding bin is capable of moving between a lowered, resting position and a raised, dumping position, said trash-holding bin further comprising a purge door and an overhead door, both of said doors being capable of moving between an open position and a closed position, and further wherein said overhead door is slidably mounted to said top wall of said trash-holding bin and wherein said purge door is hingedly mounted along said rear edge of said top wall;
- a pair of U-shaped main dumpster-lifting arms operably connected to said frame member at a main lift arm pivot pin and capable of lifting items for placement into said trash-holding bin;
- a wireless signal receiver that receives and interprets signals from a remote-control device, said wireless signal receiver being supported by said frame member;
- a battery power supply coupled with said wireless signal receiver and supported by said frame member;
- a plurality of servo motors for rotating said pair of U-shaped main dumpster-lifting arms about said main lift arm pivot pin, opening said overhead door, opening said purge door, and moving said trash-holding bin between said resting position and said dumping position;
- a suspension system supportingly connecting said plurality of tires to said frame member;
- and
- an elevation system for lifting said trash-holding bin into said raised, dumping position and lowering said trash-holding bin into said lowered, resting position, said elevation system comprising
- a can-lift actuator arm;
- a can lifting tower affixed to said bottom wall;
- a lift force transfer arm rotatably connected at a first pivot connection to said can-lift actuator arm, and rotatably connected at a second pivot connection to said can lifting tower;
- and
- a central lift-assist cylinder.
