Refuse ejection door

In a material compaction and ejection system having a storage compartment substantially defined by a forward, extendable discharge blade in nonextended position, two stationary side walls, a rearward ejection door, a supporting floor and top cover means, said storage compartment having means for receiving and compacting said material therein, an improved rearward ejection door system comprising:

• a. an upwardly extendable ejection door having an upper member fixed in an approximate vertical orientation with respect to said storage compartment when extended and a lower member connected to said upper member by a hinge means at a horizontal line across the width of said upper member and operable when unimpeded to rotate in a rearward direction about said hinge means in response to an applied force;
• b. guide means operable to maintain said upper member of the ejection door in a substantially fixed path of movement relative to said storage compartment during upward extension and retraction of said door, said guide means permitting free rearward movement of said lower member about said hinge axis when said lower section is otherwise unimpeded by a locking means;
• c. means for extending and retracting said door along said fixed path of movement during refuse ejection operations;
• and
• d. locking means operable to retain said lower hinged member in closed configuration with respect to said compartment when said ejection door is in the nonextended position.
