Abstract

The display space of a multiple door display merchandiser is illuminated by one or more vertically extending lamps (80) disposed intermediate the vertical sides of an access opening to the display space. A multiple door assembly (44) covers the access opening. To enhance the illumination of the display space, a pair of vertically extending side reflectors (92) are provided, one extending along one side of the access opening and the other extending along the other side of the access opening. An additional reflector may be mounted to an interior facing surface of the door along an upper front region of the door and/or a lower front region.

Claims

1. A display merchandiser having an improved lighting system for illuminating a display space of said display merchandiser, said display merchandiser comprising:

a structure defining an access opening in a front side wall through which at least a portion of the display space may be accessed, the access opening bounded by a first vertically extending side wall and a second vertically extending side wall being opposite said first vertically extending side wall;

a door assembly covering the access opening, said door assembly including a plurality of transparent doors, each door being selectively positionable between a first position in which it closes over the access opening to the display space and a second position in which it opens to provide access to the display space;

at least one mullion extending vertically upright through the access opening in the front side wall, each mullion dividing one transparent door of the plurality of transparent doors from another transparent door of the plurality of transparent doors;

at least one vertically extending lamp disposed behind the at least one mullion intermediate the first vertically extending side wall and the second vertically extending side wall of the access opening, said at least one lamp for emitting light into the display space;

a first reflector having a first oblique portion extending obliquely from said front side wall to said first vertically extending side wall of said access opening, and facing inwardly toward the interior product display space, said first oblique portion adapted to direct at least a portion of the light emitted from said at least one vertically extending lamp into the display space; and

a second reflector having a second oblique portion extending obliquely from said front side wall to said second vertically extending side wall of said access opening, and facing inwardly toward the interior product display space, said second oblique portion adapted to direct at least a portion of the light emitted from said at least one vertically extending lamp into the display space.

2. A display merchandiser as recited in claim 1 wherein each door comprises a glass door having a glass panel mounted in a perimeter support frame.

3. A display merchandiser as recited in claim 1 wherein each door comprises a glass door selectively pivotal between its first and second positions.

4. A display merchandiser as recited in claim 1 wherein said first and second said reflectors have a portion extending generally parallel to said first vertically extending side wall and said second vertically extending side wall to direct at least a portion of the light emitted from said lamp back across said glass door assembly.

5. A display merchandiser as recited in claim 1 further comprising:

a horizontally extending reflective surface disposed on an interior facing surface along an upper portion of at least one door of said plurality of doors; and

a horizontally extending reflective surface disposed on an interior facing surface along a lower portion of at least one door of said plurality of doors.

6. A refrigerated merchandiser having an improved lighting system for illuminating an interior product display space within said merchandiser, said refrigerated merchandiser comprising:

a refrigerated cabinet defining the interior display space bounded by a top, a base, a surrounding side wall structure including a plurality of insulated side walls extending between said top and said base, and an opening in the surrounding side wall structure through which the interior product display space may be accessed, the access opening bounded by a first vertically extending side and a second vertically extending side being opposite said first side;

a door assembly covering the access opening, said door assembly including a plurality of doors, each door having a transparent viewing area through which at least a portion of the interior product display space can be viewed, each door being selectively positionable between a first position in which it closes the access opening to access to the interior product display space and a second position in which it opens the access opening to access to the interior product display space;

at least one mullion extending vertically upright through the access opening, each mullion dividing one door of the plurality of doors from another door of the plurality of doors;

a vertically extending lamp disposed behind the at least one mullion intermediate the first side and the second side of the access opening, said lamp for emitting light into the display space;

a first reflector disposed along the first side of said access opening, said first reflector having a first portion extending obliquely to said first vertically extending side and adapted to direct at least a portion of the light emitted directly from said lamp into the display space; and

a second reflector disposed along the second side of said access opening, said second reflector having a second portion extending obliquely to said second vertically extending side and adapted to direct at least a portion of the light emitted from said lamp into the display space.

7. A refrigerated merchandiser as recited in claim 6 further comprising:

a mullion extending vertically upwardly across the access opening intermediate the first side and the second side of the access opening.

8. A refrigerated merchandiser as recited in claim 7 wherein said vertically extending lamp is mounted to said mullion.

9. A display merchandiser as recited in claim 6 wherein each door comprises a glass door having a glass panel mounted in a perimeter support frame.

10. A display merchandiser as recited in claim 9 wherein each door comprises a glass door selectively pivotal between its first and second positions.

11. A display merchandiser as recited in claim 6 wherein said first and second said reflectors have a portion extending generally parallel to said first vertically extending side wall and said second vertically extending side wall to direct at least a portion of the light emitted from said lamp back across said glass door assembly.

12. A display merchandiser as recited in claim 6 further comprising:

a horizontally extending reflective surface disposed on an interior facing surface along an upper portion of at least one door of said plurality of doors; and

a horizontally extending reflective surface disposed on an interior facing surface along a lower portion of at least one door of said plurality of doors.
