Abstract
A safety and assist mechanism for a flip chute hingedly connectable to a main chute for movement about a transverse hinge axis between a stored position over the main chute and a working position as an extension to the main chute. The mechanism has a lever rigidly securable to the flip chute to rotate with the flip chute about the hinge axis. A spring is connectable to the lever and to the main chute to generate a moment about the hinge axis contra to a moment generated by the weight of the flip chute.
