ABSTRACT:
An improved dump mechanism for a toy truck includes a dump lever having an upper surface curving downward toward the lifting end of the dump lever to engage an undersurface of the dump body. The curved surface of the dump lever is shaped for pivoting the dump body in increments that increase successively relative to corresponding successively equal pivotal increments of the dump lever throughout at least the initial half of the motion of the dump body from a load position to a full-dump position. This makes the pivoting of the dump body with the dump lever relatively easy with approximately even torque on the dump lever throughout the dumping motion.
