ABSTRACT:
Described is a remotely controlled miniature model trash truck with operating features that simulate those of a full size trash truck. The truck features moveable and controllable forks, fork frames, top access door, rear door, and an ejector blade. The mechanisms are remotely controllable by a direct current electric motor. The preferred motors are electric servo motors. The doors are actuable by the motors rotating eccentrics which are linked by rigid rods to the operating doors. An ejector blade is longitudinally moveable within the truck body by threadable engagement with a electric motor driven lead screw longitudinally mounted between the front end and rear opening of the truck box. The front fork frame is pivotally attached to the truck chassis and swingable between a loading position and dumping position by controllable excitation of a remotely controlled motor. Front forks are pivotally attached to the fork frame and positionable by actuation of a remotely controlled motor. The linkage from the front fork motor to the forks is via a series of control rods and rotary motion discs that transform the rotational motion of the motor to a reciprocating motion for transmission around the frame and thence back to a rotational motion.
