Abstract
A hermetically sealed multi-pane window assembly comprises first and second windowpane sheets formed of transparent materials. A first sealing member has an inner edge and an outer edge, the inner edge being hermetically attached around the periphery of the first windowpane sheet by diffusion bonding. A second sealing member has an inner edge and an outer edge, the inner edge being hermetically attached around the periphery of the second windowpane sheet by diffusion bonding and the outer edge being hermetically attached to the outer edge of the first sealing member. A spacer assembly is disposed between the first and the second windowpane sheets for maintaining a gap therebetween, whereby a hermetically sealed cavity is defined between the first and the second windowpanes.
Claims43
A hermetically sealed multi-pane window assembly comprising:
- a first windowpane sheet formed of a transparent material and having a periphery;
- a first sealing member having an inner edge and an outer edge, the inner edge being diffusion bonded to the first windowpane sheet around the periphery to create a hermetic seal therebetween;
- a second windowpane sheet formed of a transparent material and having a periphery;
- a second sealing member having an inner edge and an outer edge, the inner edge being diffusion bonded to the second windowpane sheet around the periphery to create a hermetic seal therebetween;
- a spacer assembly disposed between the first and the second windowpane sheets for maintaining a gap therebetween, the spacer being slidably movable with respect to at least one of the first and second windowpane sheets;
- and
- the outer edge of the first sealing member being hermetically attached to the outer edge of the second sealing member;
- whereby a hermetically sealed cavity containing the spacer assembly is formed between the first and the second windowpanes.
A hermetically sealed multi-pane window assembly comprising:
- a first windowpane sheet formed of a transparent material and having a periphery;
- a second windowpane sheet formed of a transparent material and having a periphery;
- a spacer assembly disposed between the first and the second windowpane sheets for maintaining a gap therebetween, the spacer assembly including a first layer with a first sheet-like substrate portion formed of a transparent material and a first plurality stand-offs formed integrally with the substrate portion, the stand-offs being disposed across and projecting outward from at least one surface of the substrate portion;
- and
- a sealing assembly hermetically attached around the periphery of the first windowpane sheet by diffusion bonding and hermetically attached around the periphery of the second windowpane sheet by diffusion bonding and creating a hermetic seal between the windowpane sheets whereby a hermetically sealed cavity is defined between the first and the second windowpanes.
A hermetically sealed multi-pane window assembly comprising:
- a first windowpane formed of a transparent material and having a periphery;
- a first sealing member having an inner edge and an outer edge, the inner edge hermetically sealed to the first windowpane around the periphery;
- a second windowpane formed of a transparent material and having a periphery, the second windowpane being spaced-apart from the first windowpane;
- a second sealing member having an inner edge and an outer edge, the inner edge being hermetically sealed to the second windowpane around the periphery, and the outer edge being hermetically attached to the outer edge of the first sealing member;
- and
- at least one of the first and second sealing members being compliant to enable relative movement between the first and second windowpanes;
- whereby a hermetically sealed cavity is formed between the first and the second windowpanes.
A window assembly in accordance with claim 437, further comprising:
- a viewing area defined across the center of the windowpanes where visibility through the window assembly is not blocked by the sealing members;
- and
- wherein the spacer is disposed between the windowpanes and occupies at least 10% of the viewing area.
