Abstract: A central vacuum system connectable to an interior portion of an inhabitable structure includes a housing having an upper end, a lower end, and a side wall defining a collection chamber, the side wall defining an opening communicating between atmosphere and the collection chamber, and a vacuum motor supported in the housing and being operable to move debris from the interior portion into the collection chamber.

Abstract: A door and hinge apparatus allowing quick connection and disconnection with respect to a frame, such as a cabinet frame. The door includes at least two generally elliptical slots. The generally elliptical slots have an enlarged opening and a narrower slot portion located above the enlarged opening. Mounting posts having enlarged heads protrude from one hinge leaf. The door attaches by placing the enlarged openings over the enlarged heads and sliding the door to engage the narrow slot portions with the enlarged heads. An aperture in the second hinge leaf aligns with an aperture associated with the door, and a locking plug is inserted through both apertures to prevent the door from sliding off the mounting posts.
