Abstract

Abstract A method of converting single pane glass to multiple pane hermetically sealed insulating glass without removing the existing glass sash and frame by using a preformed elastomeric (neoprene) glazing gasket as a mechanical seal. The preformed neoprene rubber seal glazing gasket is supported on a suitable frame of metal, aluminum, or other construction material. The glazing gasket support frame is attached to the existing sash or frame with suitable fastner. The preformed elastomeric glazing gasket is mechanically compressed against the existing lite of glass by the force of the fastner when the support frame is tightened against the existing sash or frame. This mechanical compression of the preformed elastomeric glazing gasket against the existing lite of glass forms a seal that is impervious to air and water vapor. The preformed elastomeric glazing gasket is grooved for support of the second lite of glass that is required to form the multiple pane hermetically sealed insulating glass unit. To effect the seal between the glazing gasket and second lite of glass, a special rubber locking strip is inserted progressively into another groove that is provided in the preformed gasket. This puts the gasket under sufficient compression to produce the required sealing pressure between the neoprene and glass. A suitable water vapor removal desiccant is placed in another groove in the neoprene gasket in the air gap space between the multiple lites of glass to control condensation.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 123 words
An assembly for adding a glass pane to an existing window without removing the existing sash and frame comprising; a support frame defining a continuous inwardly directed flange which may be secured to the sash spaced from the existing pane, a gasket having two slots opening away from each other, a sealing rib extending generally perpendicular to the two slots and a groove opposite the sealing rib, such that one slot engages the continuously inward directed flange, the other slot engages the additional pane, the sealing rib abuts the existing pane to seal the space between it and the additional pane, and a retaining strip which may be snapped into the groove opposite the sealing rib to secure the additional pane in place.
Claim 2
Dependent Claim 123 words
An assembly for adding a glass pane to an existing window without removing the existing sash and frame comprising; a support frame defining a continuous inwardly directed flange which may be secured to the sash spaced from the existing pane, a gasket having two slots opening away from each other, a sealing rib extending generally perpendicular to the two slots and a groove opposite the sealing rib, such that one slot engages the continuously inward directed flange, the other slot engages the additional pane, the sealing rib abuts the existing pane to seal the space between it and the additional pane, and a retaining strip which may be snapped into the groove opposite the sealing rib to secure the additional pane in place.
Claim 3
Dependent Claim 39 words
An assembly according to claim 1 in which a groove is provided in the gasket between the slot for engaging the additional pane and the sealing rib, and further comprising a tubular perforated desiccant container laid within the slot.
Claim 4
Independent Claim 134 words
A method of adding a glass pane to an existing window without removing the existing sash and frame which comprises the steps for (a) fixing a supporting frame to the existing sash, said supporting frame defining a continuous inwardly directed flange, (b) placing a gasket upon the flange of the supporting frame, said gasket having two slots opening away from each other the one slot being placed over the said flange, (c) placing the added pane into the other slot in the gasket, said gasket having a sealing rib extending perpendicular to the slots and abutting the existing pane to seal a space between the two panes, and (d) placing a retaining strip into the gasket in a groove provided therefore opposite the sealing rib to lock the added pane and gasket into position.
Claim 5
Independent Claim 134 words
A method of adding a glass pane to an existing window without removing the existing sash and frame which comprises the steps for (a) fixing a supporting frame to the existing sash, said supporting frame defining a continuous inwardly directed flange, (b) placing a gasket upon the flange of the supporting frame, said gasket having two slots opening away from each other the one slot being placed over the said flange, (c) placing the added pane into the other slot in the gasket, said gasket having a sealing rib extending perpendicular to the slots and abutting the existing pane to seal a space between the two panes, and (d) placing a retaining strip into the gasket in a groove provided therefore opposite the sealing rib to lock the added pane and gasket into position.
