Abstract

A refrigerated enclosure system includes an enclosure with an interior region defined between a top portion and a bottom portion. A top rail is attached to the top portion and includes an upper hinge mount. A bottom rail is attached to the bottom portion and includes a lower hinge mount. A central axis of the lower hinge mount is positioned relative to a central axis of the upper hinge mount to enable a door secured to the upper hinge mount and the lower hinge mount to open and close relative to an opening of the enclosure. The refrigerated enclosure system also includes a first insulating layer positioned on a back side of the top rail and within the interior region and a second insulating layer positioned on a back side of the bottom rail and within the interior region. The first and second insulating layers inhibit a transfer of heat into the enclosure.

First claim

What is claimed is:

1. A refrigerated enclosure system comprising:
an enclosure comprising an interior region defined between a top portion and a bottom portion;
a top rail attached to the top portion, wherein the top rail comprises a first mounting face and an upper hinge mount;
a bottom rail attached to the bottom portion, wherein the bottom rail comprises a second mounting face and a lower hinge mount;
wherein a central axis of the lower hinge mount is positioned relative to a central axis of the upper hinge mount to enable a door secured to the upper hinge mount and the lower hinge mount to open and close relative to an opening of the enclosure;
a first insulating layer positioned on a back side of the top rail and within the interior region;
a second insulating layer positioned on a back side of the bottom rail and within the interior region;
wherein the first and second insulating layers inhibit a transfer of heat into the enclosure; and
wherein the upper and lower hinge mounts comprise a recess formed through the first and second mounting faces, respectively.

2. The refrigerated enclosure system of claim 1 , comprising:
a vertical support attached at a first end to the top portion of the enclosure and at a second end at the bottom portion of the enclosure; and
wherein the vertical support is disposed within the interior region of the enclosure.

3. The refrigerated enclosure system of claim 2 , comprising a lighting system secured to the vertical support.

4. The refrigerated enclosure system of claim 2 , wherein the top rail, the bottom rail, and the vertical support eliminate a need for a frame to which the door is attached.

5. The refrigerated enclosure system of claim 1 , comprising:
a light rail secured to the top portion of the enclosure; and
a lighting system secured to the light rail.

6. The refrigerated enclosure system of claim 1 , comprising a cold-air vent system, the cold-air vent system comprising:
a header portion coupled to the top portion of the enclosure to allow cold air from the interior region to be communicated into the header portion; and
a vent coupled to the header portion to communicate the cold air to an area in front of the enclosure.

7. The refrigerated enclosure system of claim 1 , comprising a plurality of shelves disposed within the interior region and adapted to store and display a plurality of products.

8. The refrigerated enclosure system of claim 1 , wherein the first and second insulating layers comprise U-Values of 0.460 BTU/hr-ft 2 -° F. or lower.

9. A door-mounting system comprising:
a top rail securable to an upper portion of a structure, the top rail comprising a first mounting face oriented downwards and a first hinge mount associated with the first mounting face;
a bottom rail securable to a lower portion of the structure, the bottom rail comprising a second mounting face oriented upwards towards the first mounting face and a second hinge mount associated with the second mounting face;
wherein a central axis of the second hinge mount is positioned relative to a central axis the first hinge mount to enable a door secured to the first hinge mount and the second hinge mount to pivot relative to the top rail and the bottom rail;
a first insulating layer positioned on a back side of the top rail;
a second insulating layer positioned on a back side of the bottom rail;
wherein the first and second insulating layers inhibit heat transfer from an area in front of the top rail and the bottom rail to an area behind the top and the bottom rail; and
wherein the first and second hinge mounts comprise a recess formed through the first and second mounting faces, respectively.

10. The door-mounting system of claim 9 , wherein the structure is a refrigerated enclosure.

11. The door-mounting system of claim 9 , comprising a vertical support attached at a first end to the upper portion of the structure and at a second end to the lower portion of the structure, and wherein the vertical support is disposed within an interior region of the structure.

12. The door-mounting system of claim 11 , comprising a lighting system secured to the vertical support.

13. The door-mounting system of claim 9 , comprising:
a bracket secured to the back side of the top rail; and
a lighting system secured to the bracket.

14. The door-mounting system of claim 9 , comprising:
a bracket secured to the back side of the bottom rail; and
a lighting system secured to the bracket.

15. The door-mounting system of claim 9 , comprising a cold-air vent system comprising:
a header portion that is coupled to the upper portion of the structure to allow cold air from an interior region of the structure to be communicated into the header portion; and
a vent that is coupled to the header portion to communicate the cold air to an area in front of the structure.

16. The door-mounting system of claim 9 , wherein the first and second insulating layers comprise U-Values of 0.460 BTU/hr-ft 2 -° F. or lower.

17. A door-mounting system comprising:
a top rail securable to an upper portion of a structure, the top rail comprising a first mounting face oriented downwards and a first hinge mount associated with the first mounting face;
a bracket secured to a back side of the top rail;
a lighting system secured to the bracket
a bottom rail securable to a lower portion of the structure, the bottom rail comprising a second mounting face oriented upwards towards the first mounting face and a second hinge mount associated with the second mounting face; and
wherein a central axis of the second hinge mount is positioned relative to a central axis the first hinge mount to enable a door secured to the first hinge mount and the second hinge mount to pivot relative to the top rail and the bottom rail.
