Abstract

An electric outlet assembly adapted for mounting in an opening in a wall to secure a current take-off means at various fixed positions relative to the opening. The take-off means is mounted in a cover member which is arranged to block the opening at all positions at which the current take-off means is secured. Positive or negative air pressure can be maintained within the wall. The wall can be an air conduit partition in a refrigerated display cabinet.

Claims

1. A refrigerated display cabinet having spaced walls therein for forming at least one air conduit for enabling the circulation of refrigerated air and having vertically movable assembly means supported by one of said spaced walls, comprising at least one opening formed in a wall of said air conduit, a cover member in contact with said wall and arranged for vertical movement relative to and for blocking said opening, and an electrical current take-off means supported in said cover member, said cover member and said take-off means substantially flush with the side of said wall on which said assembly means is supported and means for securing said cover member in variable vertical positions relative to said opening for enabling said current take-off means to be used at different vertical positions to avoid blockage of said take-off means by said vertically movable assembly means.

2. The refrigerated display cabinet according to claim 1, wherein said current take-off means has at least one electrical conductor attached to one side thereof, and wherein said electrical conductor leads away from one side of said conduit wall, and wherein said cover member is positioned adjacent to said conduit wall on the same side as said electrical conductor.

3. The refrigerated display cabinet according to claim 1, wherein said current take-off means has at least one electrical conductor attached to one side thereof, and wherein said electrical conductor leads away from one side of said conduit wall, and wherein said cover member is positioned adjacent to said conduit wall on the opposite side from said electrical conductor.

4. The refrigerated display cabinet according to claim 1, wherein said electrical current take-off means is a plug connector receptacle.

5. The refrigerated display cabinet according to claim 1, wherein said electrical current take-off means is a unitary plug connector receptacle adapted to secure said cover member in variable vertical positions.

6. The refrigerated display cabinet according to claim 1, wherein said air conduit contains refrigerated air under a positive pressure with respect to ambient pressure.

7. The refrigerated display cabinet according to claim 1, wherein, said means for securing said cover member in variable vertical positions comprises resilient collar portions integrally formed on said current take-off means which are adapted to elastically compress said cover member against portions of said wall.

8. The refrigerated display cabinet according to claim 1, wherein said current take-off means comprises a housing portion containing electrical connectors, a face portion positioned on the opposite side of said wall from said housing portion, and wherein said cover member is positioned between said housing portion and said face portion.

9. The refrigerated display cabinet according to claim 8, wherein said means for securing said cover plate in variable vertical positions enables the exertion of compressive force between said housing and said face portions of said current take-off means.

10. A refrigerated display cabinet having spaced walls therein for forming at least one air conduit for enabling the circulation of refrigerated air, comprising at least one opening formed in a wall of said air conduit, a cover member arranged for movement relative to and for blocking said opening, and an electrical current take-off means supported in said cover member, and means for securing said cover member in variable vertical positions relative to said opening, said cabinet having a shelf adapted for being adjustably mounted at variable vertical positions on said wall, a lighting fixture attached to said shelf and wherein said current take-off means and said cover member are movable relative to said shelf to avoid blockage thereby, and wherein said light fixture has an electrical line connector adapted for connection to said current take-off means.

11. The improvement in a refrigerated display cabinet having spaced walls therein forming at least one air conduit for enabling the circulation of a refrigerated air band, said cabinet having at least one opening formed in a wall of said air conduits and having a shelf vertically adjustably mounted on said air conduit wall, the improvement comprising:

a cover member arranged for movement relative to and adapted for blocking said opening, and an electrical current take-off means supported by said cover member, means for securing said cover member in variable vertical positions relative to said opening, and a lighting fixture having an electrical connector adapted for connection to said current take-off means affixed to said shelf.

12. The improvement in a refrigerated display cabinet having spaced walls therein forming at least one air conduit for enabling the circulation of a refrigerated air band, said cabinet having at least one opening formed in a wall of said air conduits, and having a shelf adapted for being adjustably mounted at variable vertical positions on said wall of said air conduit and a lighting fixture attached to said shelf, the improvement comprising:

a cover member arranged for movement relative to and adapted for blocking said opening, and an electrical current take-off means supported by said cover member, means for securing said cover member in variable vertical positions relative to said opening, and said current take-off means and said cover member movable relative to said shelf to avoid blockage thereby.
