Claims
- 1. A door assembly for substantially closing a door opening, said door assembly comprising:
- a sealing element for being disposed adjacent to an outer surface of the periphery of said door opening, and substantially closing said door opening; and
- frame member means for being disposed about and adjacent to an outer surface of the periphery of said door opening;
- said frame means comprising inflatable means and a plurality of force generating means for applying a purality of forces to said sealing element about the periphery of said door opening;
- said inflatable means being disposed to extend said plurality of force generating means adjacent said sealing element at a plurality of points for pressing said sealing element against the periphery of said door opening;
- wherein said sealing element comprises a light weight shield; and
- wherein said light weight shield comprises sheet metal;
- wherein said frame member means comprises a hollow profile frame having at least one end;
- wherein said inflatable means is disposed within said hollow profile frame;
- wherein said inflatable means comprises at least one inflatable hose;
- wherein said plurality of force generating means comprise slidable tappets for sliding back and forth within said frame means;
- wherein said slidable tappets comprise elongated cylindrical elements disposed in holes in said frame member means which comprise a hollow profile frame;
- wherein said tappets include head means for being in contact with said at least one inflatable hose;
- wherein said at least one inflatable hose applies substantially equal force to all said slidable tappets;
- wherein said at least one inflatable hose is configured to receive a coolant therein;
- wherein said at least one inflatable hose is positioned at the end of said frame that is farthest away from said door opening; and
- wherein said tappets are interposed between said at least one inflatable hose and said sealing element to maintain a sufficient separation between said at least one inflatable hose and said door opening to minimize heat transfer from said door opening to said at least one inflatable hose.
- 2. A door assembly for substantially closing a door opening according to claim 1, wherein said frame member means comprises means adapted to fit against an at least one shape of said inflatable means.
- 3. A door assembly for substantially closing a door opening according to claim 1, wherein said at least one inflatable hose comprises at least one pneumatic hose.
- 4. The door assembly of claim 3, wherein said hollow profile frame has a substantially rectangular cross-section.
- 5. The door assembly of claim 4, wherein said sealing element defines an out of planar configuration.
- 6. The door assembly of claim 5, further including coolant means positioned within said at least one inflatable hose.
- 7. The door of claim 6, wherein said at least one inflatable hose is constructed from at least one material selected from the group consisting essentially of: a) Teflon, b) silicon, and c) rubber.
- 8. A door assembly for substantially closing a door opening according to claim 1, wherein said sealing element comprises a light weight shield.
- 9. A door assembly for substantially closing a door opening according to claim 8, wherein said light weight shield comprises sheet metal.
- 10. A door assembly for substantially closing a door opening according to claim 8, wherein said at least one inflatable hose comprises at least one multi-chambered hose.
- 11. A door assembly for substantially closing a door opening according to claim 10, wherein said at least one multi-chambered hose comprises a web therein.
- 12. A door assembly for substantially closing a door opening according to claim 11, wherein said at least one multi-chambered hose comprises several hoses.
- 13. The door of claim 12, wherein said hollow profile frame has a substantially rectangular cross-section.
- 14. The door of claim 13, wherein said sealing element defines an out of planar configuration.
- 15. The door of claim 14, further including coolant means positioned within said at least one inflatable hose.
- 16. The door of claim 15, further including biasing means for moving said tappets relative to said hollow profile frame.
- 17. The door of claim 16, wherein said biasing means is spring means.
- 18. The door of claim 17, wherein said at least one inflatable hose is constructed from at least one material selected from the group consisting essentially of: a) Teflon, b) silicon, and c) rubber.
- 19. The door of claim 12, wherein said hollow profile frame has an at least partially rounded cross-section.
- 20. The door of claim 19, wherein said sealing element defines an out of planar configuration.
- 21. The door of claim 20, further including coolant means positioned within said at least one inflatable hose.
- 22. The door of claim 21, further including biasing means for moving said tappets relative to said hollow profile frame.
- 23. The door of claim 22, wherein said biasing means is spring means.
- 24. The door of claim 23, wherein said at least one inflatable hose is constructed from at least one material selected from the group consisting essentially of: a) Teflon, b) silicon, and c) rubber.
