Abstract

One aspect of the invention features a refrigerated display case door that includes a hinge rail, a panel assembly, and a handle. The hinge rail includes a channel portion and a hinge receiving portion. The panel assembly includes two panes of glass bounding a sealed space between the panes, and includes a first edge disposed within the channel portion of the hinge rail. The handle is secured to a surface of the panel assembly proximate a second edge of the panel assembly opposite the first edge. The sealed space is closed by a peripheral seal disposed between the panes along a periphery of the panes. The peripheral seal includes a first material extending along a first portion of the periphery and a second material extending along a second, different portion of the periphery, where the second material is more transparent to visible light than the first material.

Claims

1. A refrigerated display case door, comprising:

a hinge rail comprising a channel portion and a hinge receiving portion;

a panel assembly comprising two panes of glass bounding a sealed space between the panes, the panel assembly having a first edge disposed within the channel portion of the hinge rail; and

a handle secured to a surface of the panel assembly proximate a second edge of the panel assembly opposite the first edge;

wherein the sealed space is closed by a peripheral seal disposed between the panes along a periphery of the panes, the peripheral seal comprising a first material extending along a first portion of the periphery and a second material extending along a second, different portion of the periphery, and

wherein the second material is more transparent to visible light than the first material.

2. The door of claim 1, wherein the second material has a higher transmittance of visible light than that of the first material.

3. The door of claim 1, wherein the peripheral seal is exposed to the sealed space between the panes.

4. The door of claim 1, wherein the first portion of the periphery is along the first edge of the panel assembly.

5. The door of claim 4, wherein the hinge rail is arranged to cover the peripheral seal applied along the first edge.

6. The door of claim 1, wherein the first portion of the periphery is along the first edge, a third edge, and a fourth edge of the panel assembly.

7. The door of claim 1, wherein the second portion of the periphery is along the second edge of the panel assembly.

8. The door of claim 1, wherein edge guards are coupled to the second edge and the third edge.

9. The door of claim 1, wherein a transparent edge guard is coupled to the second edge.

10. The door of claim 9, wherein the transparent edge guard comprises a wiper configured to seal the door when the door is in a closed position.

11. The door of claim 1, wherein the sealed space is filled with an insulating gas.

12. The door of claim 11, wherein the peripheral seal is exposed to the insulating gas within the sealed space.

13. The door of claim 1, wherein the sealed space is evacuated below atmospheric pressure.

14. The door of claim 13, wherein the peripheral seal is exposed to vacuum pressure in the sealed space.

15. A refrigerated display case comprising:

a frame; and

a first display case door and a second display case door mounted to the frame, each of the first display case door and the second display case door comprising;

a hinge rail comprising a channel portion and a hinge receiving portion;

a panel assembly comprising two panes of glass bounding a sealed space between the panes, the panel assembly having a first edge disposed within the channel portion of the hinge rail; and

a handle secured to a surface of the panel assembly proximate a second edge of the panel assembly opposite the first edge;

wherein the sealed space is closed by a peripheral seal disposed between the panes along a periphery of the panes, the peripheral seal comprising a first material extending along a first portion of the periphery and a second material extending along a second, different portion of the periphery, and

wherein the second material is more transparent to visible light than the first material.

16. The refrigerated display case of claim 15, wherein the second material has a higher transmittance of visible light than that of the first material.

17. The refrigerated display case of claim 15, wherein the second portion of the periphery is along the second edge of the panel assembly.

18. The refrigerated display case of claim 15, wherein each of the first display case door and the second display case door comprise a transparent edge guard coupled to the second edge of the panel assembly, the transparent edge guard having a wiper extending outward therefrom, and

wherein the first display case door and the second display case door are arranged within the frame such that, when closed, the transparent edge guard wipers cooperate with each other to establish a seal between the first display case door and the second display case door.

19. A refrigerated display case door, comprising:

a hinge rail comprising a channel portion and a hinge receiving portion;

a panel assembly comprising two panes of glass bounding a sealed space between the panes, the panel assembly having a first edge disposed within the channel portion of the hinge rail;

a handle secured to a surface of the panel assembly proximate a second edge of the panel assembly opposite the first edge;

edge guards coupled to a top edge and a bottom edge of the panel assembly; and

a transparent edge guard coupled to the second edge of the panel assembly,

wherein the sealed space is closed by a peripheral seal disposed between the panes along a periphery of the panes, the peripheral seal comprising a first material and a second material, the first material extending along a first portion of the periphery including the first edge, the top edge, and the bottom edge of the panel assembly, the second material extending along a second portion of the periphery including the second edge of the panel assembly, and

wherein the second material is more transparent to visible light than the first material.

20. The door of claim 19, wherein the second material has a higher transmittance of visible light than that of the first material.
