eoo f *o oo *o t t ame of Applicant: TO BE COMPLETED BY APPLICANT TYLER REFRIGERATION CORPORATION Actual Inventor(s): Thomas E. Kennedy Address for Service: CALLINAN LAWRIE, 278 High Street, Kew, 3101, Victoria, Australia Invention Title: "EDGE SEAL GASKET ASSEMBLY FOR A MULTIPLE GLAZING
UNIT"
The following statement is a full description of this invention, including the best method of performing it known to me:- 12/9/96LP8877.CS,1 EDGE SEAL GASKET ASSEMBLY FOR A MULTIPLE GLAZING UNIT This invent on relates to an edge seal gasket assembly for use in a multiglazed window or door and, in particular, an edge seal gasket assembly with a flange gasket fittec into an inset spacer and extending outward from the multiglazed door- Background of the Invention Single and multi-glazed door and window units are used in many applications. In applications where heat transfer is a concern, such as refrigerators, multi-glazed units are preferred. The vacuum enclosure created by the spaced panes of glass red ce heat transfer across the window or door surface, Conventional mulli-glazed doors use edge seal assemblies with elongated spacers to separate the panes of glass and sealant compounds to secure the panes together and vacuum seal the e closed interior. Hinged or sliding glass window or doors require additional edge seals or gaskets around the periphery of the doors to prevent heat trans er through the gaps between the sides of the refrigerator cases and the glass doo s. Because of the construction of conventional edge seal assemblies, multi-glazed doors require additional edge molding or framing to support an edge gasket. The additional molding and framing increases production costs for multi-glazed doors.
Summary of the Invention The multi glazed unit of this invention includes an edge seal gasket assembly in corn ination with a pair of spaced panes of glass. The edge seal gasket assembly (f this invention allows a multi-glazed window or door to support an edge seal gasket as an integrated part of the edge seal assembly. With the edge seal gasket incorp orated into the edge seal assembly, this invention eliminates the need for any add tional molding or frame work. The edge seal gasket assembly includes an elongated flange gasket, which is preferably securely fitted into the spacer. In another embodiment, a separate conncction part can be combined with a conventional spacer. With the flange gasket so secured, the spacer being inset 1 *o *e o from the edge of the around both sides of Accordingly, gasket assembly for Another objec glazed window or dc extending from the e Other objects description.
