DEFINITION

Classification: 414/510

Three dimensional load-receiving portion includes movable load-underlying surface, and element comprises upright member attached to surface:

(under subclass 509) Apparatus wherein the load receiving portion has a significant depth dimension (e.g.,., by virtue of the provision of sidewall structure) and includes a movable floor upon which a load is supported, and wherein the load-engaging element is a member which is attached to the floor in an upright position and moves therewith.

(1) Note. While the movable floor may constitute the primary means for ejecting the load, the upright member assists therein by removing any portion of the load which adheres to, or has its outbound movement interfered with, by the sidewall structure.
