Description

ASSEMBLY OF SEALING SEALING BOARD FOR A MULTIPLE GLASS UNIT DESCRIPTION This invention relates to an assembly of edge seal gasket for use in a multi-pane window or door and in particular, a seal seal mounting edge, with an adapted ledge in an interleaved separator extending outwardly of the multi-paneled door. The single-pane and multi-pane glass door and window units are used in many applications. In applications where heat transfer is an interest, such as refrigerators, multiple glass units are preferred. The vacuum housing created by separate glass panes reduce heat transfer through the window or door surface. Conventional multi-pane doors use edge seal assemblies with elongated spacers to separate glass media and sealing compounds to secure the glass together and seal the closed interior vacuum. Articulated or sliding glass windows or doors require additional edge seals or gaskets around the periphery of the doors to prevent heat transfer through the spaces between the r side. < - > t riqerador and The glass doors. Due to the construction of conventional edge seal assemblies, multi-pane doors require an additional molded or framed edge to support an edge joint. Additional molding and framing increase production costs for multi-pane doors. The multi-crystal unit of this invention includes a flange seal gasket assembly in combination with a pair of separate glass panes. The edge seal gasket assembly of this invention allows a multi-pane window or door to support an edge seal gasket as an integrated part of the edge seal assembly. With the edge seal gasket incorporated in the edge seal assembly, this invention eliminates the need for any additional frame work or molding. The edge seal gasket assembly includes an elongated ledge seal, which is preferably securely fitted within the separator. In another embodiment, a separate connection part can be combined with a conventional separator. With the projecting gasket thus secured, the separator is sandwiched from the edge of glass frames and packaged with a sealing compound, which extends around both sides of the projecting gasket to seal and secure the glass frames together.

Accordingly, an object of this invention is to provide an edge seal gasket assembly for use with a multi-pane window or door. Another object is to provide an edge seal gasket assembly for a multi-pane window or door, which includes a protruding seal adapted within the separator and extending from the edge of the multi-unit unit to form a gasket of edge seal. Other objects will become apparent by a reading of the following description.

The glass panes 12, 14 are separated by the separator, which is sandwiched from the edge of the panes 12, 14 to form an edge cavity 16. The projection seal 30 extends beyond the edge of the panes 12, 14 from within the cavity 16. The cavity is filled with a sealing compound 22, such as a silicone gel, to secure and seal the panes 12, 14 together and to support the projecting seal 30 within the cavity 16. The seal projection 30 is constructed of any wear resistant, foldable material that is suitable for providing an air tight seal, such as butyl rubber. Both of Figures 1 and 2 show that in cross section the projecting joint 30 has an elongated axially symmetrical tapered body 32. The tapered end forms the edge seal gasket for the multi-pane door 10 as described in greater detail in the next. A flange 34 extends on either side of the body of the gasket 32. A reduced neck portion 36 extends axially from the body of the gasket 32 with the gasket ending at its inner end and at the upper 38. upper 38 has a converging tapered end, to facilitate the press fit connection of the projecting joint 30 in the separator.

Figures 1 and 2 show two different embodiments of the edge seal gasket assembly 20. Figure 1 shows the edge seal gasket assembly 20 with a one-piece separator 40. Figure 2 shows a gasket assembly. edge seal 20 with a 2-piece separator 60. Generally, both separators are extruded from a suitable material, which provides sufficient structural support and thermal insulation, such as aluminum or plastic. As shown in Figure 1, the separator 40 has a square body in cross section with four walls 41, 42, 43, 44. The side wall 42 abuts against the inner surface of the glass 12 and the side wall 44 makes butt contact against the inner surface of the glass 14. The sealing compound 22 secures the separator 40 in position between the panes 12, 14. The spacer 20 includes the converging, lateral, extension members 46, 47 extending from the corners of the panes. sides 42, 43 and 44. The side extension members 46, 47 with the wall 43 define an elongated open channel 50. Each side extension member 46, 47 includes a flange turned inward 48 in the channel 50 orifice. shown in Figure 2, the separator 60 includes a separate body part 82 and a separate connecting part 70. The body part 62 has a square cross-sectional configuration with side walls 63, 64, 65, 66. The part d side 64 makes butt contact against the interior surface of the glass 12 and the side wall 66 makes butt contact against the interior surface of the glass 14. The connection part 70 includes a backrest 71 and two converging side extension members 72. , 73. The backing 71 makes flat contact against the end wall 65 of the body part 62. The connection part 70 is secured to the body part 62 by any conventional method, such as by an adhesive and is maintained secured between the panes 12, 14 by the sealing compound 22. Alternatively, the body part 62 can be secured between the glass panes 12, 14 by an adhesive placed on either side of the side walls 64, 66 and the connecting part. 70 held in position against the body part 62 by the sealing compound 22. Again, the lateral extension members 72, 73 and rear 71 define an open, elongate channel 76. Each member of lateral extension 72, 73 includes a turned flange 74 in the orifice of the channel 76. As shown in Figures 1 and 2 for both embodiments, the projecting joint 30 is adapted within any of the modes of the separators. For simplicity, only the connection of the embodiment of Figure 1 will be described in detail herein; however, it should be understood that the connection between the outgoing joint and the mode separator in Figure 2 is in substantially the same form. The projecting joint 30 is press fit within the separator channel 50 between the spaced ridges 48, turned inwardly of the separator. The main portion 38 of the projecting joint 30 is tapered to facilitate the press fit connection within the spacer channel 50. The flanges 48 of the side extension members 46, 47 project into the grooves formed in the neck portion 36. to prevent the projecting joint 30 from being expelled from the spacer 40. The butting lips 34 abut against the outer projections 52 of the side extension members 46, 47. In both embodiments, the combination of the outgoing joint and spacer is sandwiched between the glass 12, 14 glass. The separator is sandwiched from the aligned edges of the glass panes 12, 14 to form a cavity end 16 between the panes 12, 14. The tapered end 31 of the projecting gasket 30 forms the seal joint edge for the door 10. The sealing compound 22 completely fills the cavity 16 on either side of the projecting joint 30., placed on the outer surfaces of the lateral extension members 46, 47, 72, 73. The sealing compound 22 secures the glasses 12, 14 together against the separator and provides the vacuum seal for the multi-paneled door 10. In addition, the sealing compound 22 assists in securing the projecting joint 30 in position within the cavity 16 and prevents the separator from being displaced relative to the glass panes. With the seal body 32 projecting from the cavity 16 beyond the aligned edges of the panes 12, 14, the projecting seal 30 provides a seal seal ready for engagement with the sides of the housing 2 or other seal joint of edge.
