Abstract
A toy truck simulates the dumping of granular material within a closed container which is pivotally mounted to the truck chassis and has a transparent upward facing wall to exhibit the movement of the granular material during the simulated dumping. Pivoting the container upward from its normally horizontal position causes the material to slide from a visible dumping chamber to a concealed receiving chamber, and by further pivoting of the container the material is returned to the dumping chamber for repetition of simulated dumping. A metal foil membrane may be positioned for striking by the granules to produce a sound accompanying the simulated dumping. A self-operating valve may be used to control flow of the material.

A toy truck for simulating the dumping of granular material, comprising
- a truck chassis and
- a closed container containing granular material, said container being pivotally mounted to said truck chassis and comprising
- a dumping chamber having a transparent upwardly facing wall, said dumping chamber normally extending in a generally horizontal direction,
- a receiving chamber disposed below said dumping chamber and
- an aperture of predetermined size connecting said dumping chamber and said receiving chamber, said aperture being positioned to permit said granular material to pass from said dumping chamber to said receiving chamber when said container is pivoted to an orientation with the forward portion thereof pointing forward and upward.
