US 5,950,398 A · Pass-by insulating glass window unit and method for replacing single glazing

Abstract

A pass-by insulating glass window unit for replacing single glazing including a sealing assembly sandwiched by glazings having dissimilar plane surface dimensions. One glazing, the exterior glazing, has the plane dimensions of the single glazing it replaces. The other, the interior glazing, and the sealing assembly have plane dimensions slightly smaller than the dimensions of the window opening. The pass-by insulating glass window unit is assembled with each of the four edges of the exterior glazing extending equidistantly outwardly from the aligned edges of the sealing assembly and the interior glazing. The thickness of the sealing assembly is predetermined to provide an enclosed insulating space of optimum insulating value. For use in double hung window sashes, the thickness is chosen to assure passage of the movable window openings, and to position the interior glazing to be in approximate alignment with the plane of the interior surface of the wood sash. The assembled pass-by insulating glass window unit is placed, interior glazing first, through the window opening or sash from the exterior side until the exterior glazing contacts the glazing rabbet.

Dependent claims

A pass-by multiple glazed window unit for use with a sash having a central opening with an exterior glazing seat extending thereabout for receiving a single glazing comprising;

an interior glazing dimensioned for passing through said opening,
an exterior glazing having plane dimensions greater than said interior glazing and adapted to be received in said glazing seat upon removal of said single glazing, and
a sealing assembly bonded to said interior and exterior glazing forming an hermetically sealed insulating space therebetween prior to placement in said opening.

A pass-by multiple glazed window unit for retrofitting a single glazed window having a sash adapted for mounting in a window frame and including a central opening, said sash further including an exterior glazing seat on the periphery of said central opening for receiving said single glazing, said pass-by multiple glazed window unit comprising;

an interior glazing having predetermined plane dimensions in close conformance with said central opening while permitting passage therethrough,
an exterior glazing having plane dimensions greater than said interior glazing and in close conformance with the dimensions of said glazing seat to permit seating therein upon removal of said single glazing, and
a sealing assembly extending about the peripheral edge of said interior glazing,
said sealing assembly being bonded to said exterior and interior glazings forming an hermetically sealed insulating space therebetween prior to placement of said pass-by window unit in said central opening,
whereby, enabling state-of-the-art manufacturing techniques for said pass-by multiple glazed insulating window unit off-site prior to being secured in said single glazed window sash after removal of said single glazing and without requiring removal of said sash.
