Abstract

A refrigerating door construction is disclosed which includes door rail elements form one or more spacer elements between adjacent panels so that separate, discrete spacer bars may be eliminated.

Claims

1. A refrigerator door comprising:

a plurality of panels including a forward panel and at least one rearwardly disposed panel;

a door rail element for supporting the plurality of panels such that substantially no part of the rail of at least one door rail element overlaps the forward panel wherein the door rail element includes at least one spacer element extending from the door rail element into a space between adjacent panels of the plurality of panels and wherein the spacer element is part of the door rail element; and

at least one hinge at least partly internal to the door rail element for allowing pivotal movement of the door about an axis.

2. The door of claim 1 wherein the spacer element is bonded to the adjacent glazing panels by a sealing compound.

3. The door of claim 1 wherein the spacer element includes a non-uniform surface for engaging a complimentary surface on the door rail element.

4. The door of claim 3 wherein the non-uniform surface on the spacer includes a projection and wherein the door rail includes mating recesses for accepting the projections to form an engagement between the door rail and the spacer element.

5. The door of claim 4 wherein the spacer element includes at least two projections and wherein the door rail includes at least two recesses.

6. The door of claim 4 wherein the spacer element includes recesses for accepting sealant.

7. The door of claim 1 wherein the spacer element is integral with the rail element.

8. The door of claim 7 wherein the rail includes a first projection and the spacer element includes a second projection extending toward the first projection defining a distance between them for defining a recess for sealant wider than the distance between the projections and wherein the glass panel has an edge extending into the recess.

9. The door of claim 8 wherein the rail and spacer element includes further projections for accepting sealant for bonding to the panels.

10. A refrigerator door comprising:

a first, second and third panels;

a door rail element for supporting the panels such that substantially no part of the door rail of at least one door rail element overlaps the forward panel wherein the door rail element includes at least one spacer element extending from the door rail element into a space between adjacent panels of the plurality of panels and wherein the spacer element is part of the door rail element, wherein the spacer element includes a spacer projection and a spacer recess and the rail includes a rail projection extending toward the spacer recess and a rail recess wherein the spacer projection extends toward the rail recess on the spacer element for defining a recess for accepting sealant;

sealant on the rail element and in the recess defined by the spacer element and the rail and wherein the sealant contacts and is bonded to the first, second and third panels, and wherein the first panel has first and second oppositely facing surfaces and is contacted only on one surface by the sealant; and

at least one hinge at least partly internal to the door rail element for allowing pivotal movement of the door about an axis.

11. The door of claim 10 wherein the door rail is formed from a hardened polymeric material.

12. The door of claim 11 wherein the material is a foamed PVC material.

13. The door of claim 10 wherein the spacer and the rail are formed from the same material.

14. The door of claim 13 wherein the spacer and the rail are formed from a foamed PVC material.

15. The door of claim 10 wherein the one of the rail and the spacer includes at least one projection and the other of the spacer and rail includes a recess for accepting the projection.

16. The door of claim 15 wherein the rail includes a projection which defines one side of two recesses in the rail separated by the projection for receiving projections on the spacer.

17. The door of claim 10 wherein the rail further defines an integral spacer for separating two adjacent panels.

18. A refrigerator door comprising:

a plurality of panels including a forward panel and at least one rearwardly disposed panel;

a hardened polymeric door rail element for supporting the plurality of panels such that substantially no part of the door rail of at least one door rail element overlaps the forward panel, wherein the door rail element includes a front portion and a rear portion wherein the door rail element is relatively inflexible between the front portion and the rear portion, wherein the door rail element includes at least one spacer element extending from the door rail element into a space between adjacent panels of the plurality of panels and wherein the spacer element is part of the door rail element; and

at least one hinge at least partly internal to the door rail element for allowing pivotal movement of the door about an axis.

19. The door of claim 18 wherein the spacer is integral with the rail.

20. The door of claim 18 wherein the spacer is bonded to the rail.

21. The door of claim 18 wherein the door includes two spacers and one spacer is integral with the rail and wherein one spacer is bonded to the rail.

22. The door of claim 18 wherein the door includes two spacers and both spacers are integral with the rail.

23. The door of claim 18 wherein the door rail has a material characteristic and further includes a skin layer having a material characteristic different than the material characteristic of the material in the rail underneath the skin layer.

24. The door of claim 18 wherein the door has two spacers and each spacer has grooves for accepting sealant.

25. The door of claim 24 wherein the rear glazing strip includes projections for engaging the rail.

26. The door of claim 25 wherein the glazing strip includes a soft tip for engaging a rearward panel.

27. The door of claim 18 further comprising a rear glazing strip formed from a polymeric material.

28. The door of claim 27 wherein the glazing strip is integral with the rail.

29. A refrigerator door comprising:

a plurality of panels including a forward panel and at least one rearwardly disposed panel;

a door rail element for supporting the plurality of panels such that substantially no part of the door rail of at least one door rail element overlaps the forward panel, wherein the door rail element includes a front portion and a rear portion wherein the door rail element is relatively inflexible between the front portion and the rear portion, wherein the door rail element includes at least one spacer element extending from the door rail element into a space between adjacent panels of the plurality of panels and wherein the spacer element is part of the door rail element; and

at least one hinge at least partly internal to the door rail element for allowing pivotal movement of the door about an axis.
