Abstract

A window insert for a door includes opposing outer and inner panes, a spacer disposed between and spacing the panes, a first seal forming a seal between the panes, a frame having an outer frame element and an inner frame element sandwiching the panes, and a waterproof welded joint extending about the periphery of the frame elements.

Claims

1. A window insert for a door comprising:

opposing outer and inner panes;

a spacer disposed between and spacing the panes;

a first seal forming a seal between the panes;

a frame having an outer frame element and an inner frame element sandwiching the panes;

a waterproof welded joint extending about the periphery of the frame elements; and

a second seal between the inner frame element and the inner pane;

wherein at least one of the inner and outer frame elements encapsulates at least one of the panes such that the at least one of the inner and outer frame elements overlies an inner surface and an outer surface of the at least one of the panes.

2. The window insert of claim 1 wherein the outer frame element comprises an outer flange overlying the outer pane, the inner frame element comprises an inner flange overlying the inner pane, and the second seal is positioned between the inner flange and the inner pane.

3. The window insert of claim 2 wherein the second seal is a foam-in-place seal.

4. The window insert of claim 2 wherein the inner and outer flanges compressively retain the inner and outer panes.

5. The window insert of claim 1 wherein the inner frame element further comprises a flange extending radially away from the panes.

6. The window insert of claim 1 wherein the waterproof welded joint comprises a channel on one of the inner or outer frame elements and a weld flange on the other of the inner or outer frame elements, with the weld flange received within the channel and welded together.

7. The window insert of claim 6 wherein the waterproof welded joint comprises an extruded polypropylene rope with embedded ferrous material located within the channel.

8. The window insert of claim 1 wherein the waterproof welded joint extends about the periphery of the panes.

9. The window insert of claim 1 wherein the waterproof welded joint is continuous.

10. A window insert for a door comprising:

opposing outer and inner panes;

a spacer disposed between and spacing the panes;

a first seal forming a seal between the panes;

a frame having an outer frame element and an inner frame element sandwiching the panes; and

a waterproof welded joint extending about the periphery of the frame elements;

wherein the inner frame element comprises a flange overlying an inner surface of the door and at least one of the inner and outer frame elements encapsulates at least one of the panes such that the at least one of the inner and outer frame elements overlies an inner surface and an outer surface of the at least one of the panes.

11. The window insert of claim 10 further comprising an inner seal between the inner frame element and the inner pane.

12. The window insert of claim 11 wherein the inner frame element comprises an inner flange overlying the inner pane and the inner seal is positioned between the inner flange and the inner pane.

13. The window insert of claim 12 wherein the outer frame element comprises an outer flange overlying the outer pane.

14. The window insert of claim 13 wherein the inner flange and inner seal extend about the periphery of the inner pane and the outer flange extends about the periphery of the outer pane, and wherein the inner and outer flanges compressively retain the inner and outer panes.

15. A window insert for a door comprising:

opposing outer and inner panes;

a spacer disposed between and spacing the panes;

a first seal forming a seal between the panes;

a frame having an outer frame element and an inner frame element sandwiching the panes; and

a waterproof welded joint extending about the periphery of the frame elements;

wherein at least one of the inner and outer frame elements encapsulates at least one of the panes such that the at least one of the inner and outer frame elements overlies an inner surface and an outer surface of the at least one of the panes.

16. The window insert of claim 15 further comprising an inner seal between the inner frame element and the inner pane.

17. The window insert of claim 16 wherein the inner frame element comprises an inner flange overlying the inner pane and the inner seal is positioned between the inner flange and the inner pane.

18. The window insert of claim 17 wherein the outer frame element comprises an outer flange overlying the outer pane.

19. The window insert of claim 18 wherein the inner flange and inner seal extend about the periphery of the inner pane and the outer flange extends about the periphery of the outer pane, and wherein the inner and outer flanges compressively retain the inner and outer panes.

20. The window insert of claim 15 wherein the inner frame element further comprises a flange overlying an inner surface of the door.
