ABSTRACT:
An automatic locking mechanism for a case in which a container having an inclined surface and a ball is mounted along one side of the case and hooks are mounted on the other opposing side. The hooks engage an opening in the container when the two sides of the container are brought together. The hooks also have an inclined surface matching the inclined surface in the container to allow the ball to roll along the inclined surface to a position wedged between the hooks and container when the case is in a vertical position. Laying the case flat or horizontally causes the ball to roll along the inclined surface away from the hooks thereby releasing and unlocking the case.
