Abstract

A multi-sheet glazing unit includes a closed spacer frame, the spacer frame has one side having a pair of legs joined to a base to provide the spacer frame with a U-shaped cross-section. An inner sheet has an edge mounted in an edge receiving member mounted between the legs of the U-shaped side of the spacer frame. The remaining edges of the inner sheet are within the interior of the closed spacer frame and spaced from the spacer frame. The inner sheet is held within the spacer frame by sheet retaining members mounted to the spacer frame. A sheet e.g. glass sheet is secured by a moisture-impervious adhesive to outer surface of each of the legs of the spacer frame. One type of sheet retaining members has a horizontal member and a vertical member, and a locking member. The locking member is mounted on the horizontal member spaced from the vertical member to form a groove to hold the inner sheet within the closed interior of the spacer frame. Another type of the sheet retaining member includes a pair of flexible fingers mounted on a platform member, angled away from the platform member toward one another and having their ends spaced from one another to provide a groove to hold the inner sheet within the closed interior of the spacer frame. A method for making the unit is also disclosed.

Claims

1. An article comprising:

a spacer member having in cross section a base, upright legs connected to and extending from the base, and an extension extending from each of the legs over the base toward one another, and

a support member having a groove for receiving marginal and peripheral edges of a sheet and having a cavity or post for receiving an end portion of a muntin bar wherein the support member is supported on the extensions.

2. The article of claim 1 wherein spaced distance between the upright legs increases as the distance from the base increases.

4. The article of claim 1 wherein the base has two grooves, each of the grooves for receiving marginal and edge portions of a sheet.

6. The article of claim 1 wherein the post is detachably secured to the member.

7. The article of claim 1 wherein the post has a vertical stem extending away from the member and a plurality of fingers extending away from the vertical stem.

8. The article of claim 1 wherein the post is sized to be inserted into hollow end of a muntin bar.

9. The article of claim 1 wherein the post is a hollow member sized to receive end of a muntin bar.

10. The article of claim 1 wherein the cavity is a hole in the member sized to receive end of a muntin bar.

11. The article of claim 1 wherein the member has a first pair of opposite sides and a second pair of opposite sides, a first major surface, a second major surface opposite the first surface and the groove is on the first surface further including a support extending away from the second surface and spaced from the first pair of opposite sides.

3. An article comprising:

a platform support;

a pair of flexible fingers, each finger having a first side and an opposite side designated as a second side with the first side of one finger mounted to a side of the platform support and the first side of the other finger mounted to the other side of the platform support with the fingers extending above upper surface of the platform support toward one another, wherein the cavity is formed in or the post is mounted on the platform support adjacent outer surface of one of the fingers, and

a cavity or post in the platform support for receiving an end portion of a muntin bar.

12. The article of claim 3 wherein the platform support has a first major surface and an opposite surface defined as a second major surface with the fingers mounted on the first major surface and further comprising a support connected to the second major surface.

13. The article of claim 12 wherein the support has a shape with the vertical leg extending from the second major surface of the platform support.

14. The article of claim 3 wherein the platform support has a first major surface and an opposite surface defined as a second major surface with the fingers mounted on the first major surface and further comprising engaging members.

15. The article of claim 14 wherein the engaging members are grooves formed in the side portions between the major surfaces.

16. The article of claim 14 wherein the engaging members are tabs connected to the platform.

5. An article comprising:

a platform support having a vertical stop on the platform support;

an engaging member securable on surface of the platform support spaced from the vertical stop to form a groove wherein the cavity is formed in the platform or the post is mounted on the platform support on one side of the engaging member or vertical stop, and

a cavity or post in the platform support or engaging member for receiving an end portion of a muntin bar.

17. The article of claim 5 wherein the platform support has a first major surface and an opposite surface defined as a second major surface with the vertical stop on the first major surface and further includes a support connected to the second major surface.

18. The article of claim 17 wherein the support has a shape with the vertical leg extending from the second major surface of the platform support.

19. The article of claim 5 wherein the platform support has a first major surface and an opposite surface defined as a second major surface with the vertical stop on the first major surface and further comprising engaging members.

20. The article of claim 19 wherein the engaging members are grooves formed in the side portions between the major surfaces.

21. The article of claim 19 wherein the engaging members are tabs connected to the platform.
