Abstract

An adjustable support structure for supporting food items above melt water which accumulates in the bottom of an insulated portable ice chest. A horizontal deck supports food and ice within the ice chest above the ice chest bottom so that a volume for melt water is defined between the ice chest bottom and the horizontal deck. In some embodiments, to facilitate draining the ice chest in situ, a drain water suction pick up tube is provided having a lower portion extending downwardly from the horizontal deck into the volume. In some embodiments, the horizontal deck includes a generally rectangular main portion and a pair of adjustable wings, with supports under the main portion for positioning the horizontal deck a distance above the ice chest bottom.

Claims

1. An adjustable support structure for use in combination with a portable ice chest of the type having a bottom, four walls and a top opening with a cover, said support structure comprising:

a horizontal deck for supporting food and ice within the ice chest above the ice chest bottom, a volume for melt water being defined between the ice chest bottom and said horizontal deck;

said horizontal deck including

a generally rectangular main portion having four side edges, and

a pair of adjustable wings extending past two adjacent side edges of said main portion; and

supports under said main portion for positioning said horizontal deck a distance above the ice chest bottom.

2. The support structure of claim 1, wherein said supports are configured so as to provide direct structural support for an intermediate portion of said main portion.

3. The support structure of claim 1, wherein said supports are elongated.

4. The support structure of claim 3, wherein said supports comprise tubing which has a rectangular cross-section.

5. The support structure of claim 1, wherein said horizontal deck is substantially solid with a plurality of drainage apertures to facilitate the flow of melt water into said volume.

6. The support structure of claim 1, wherein said adjustable wings overlap said main portion of said horizontal deck.

7. The support structure of claim 6, wherein said adjustable wings are generally coplanar and have matching rabbets to allow said wings to overlap at one end of each wing.

8. The support structure of claim 1, which further comprises fasteners which selectively clamp said adjustable wings to said main portion at a desired adjustment position.

9. The support structure of claim 8, wherein said adjustable wings include slotted adjustment apertures through which said fasteners pass.

10. The support structure of claim 9, wherein said fasteners comprise either threaded apertures in said horizontal deck main portion or nuts carried by said horizontal deck main portion, and machine screws which pass through said slotted adjustment apertures to engage said threaded apertures or nuts.

11. The support structure of claim 1, which further comprises a drain water suction pick up tube having a lower portion extending downwardly from said horizontal deck into said volume, said lower portion having an end which is spaced above the ice chest bottom during use.

12. The support structure of claim 9, wherein the length of said lower portion of said drain water suction pick up tube is less than the height of said supports under said main portion.

13. The support structure of claim 11, wherein said drain water suction pick up tube has an upper portion which extends upwardly from said horizontal deck.

14. The support structure of claim 13, wherein said upper portion of said drain water suction pick up tube comprises a nipple to which a riser tube can be connected.

15. The support structure of claim 13, wherein:

said upper portion of said drain water suction tube comprises a nipple; and

which further comprises

a riser tube connected to said nipple to extend upwardly within the ice chest to facilitate connection to a suction device.

16. The support structure of claim 13, wherein:

said upper portion of said drain water suction tube comprises a nipple; and

which further comprises

a drain connection tube extending through one of the walls of the ice chest near the top opening to facilitate connection to a suction device; and

a riser tube connected to said nipple, extending upwardly within the ice chest, and connected to said drain connection tube.

17. A support structure for use in combination with a portable ice chest of the type having a bottom, four walls and a top opening with a cover, said support structure comprising:

a horizontal deck for supporting food and ice within the ice chest above the ice chest bottom, a volume for melt water being defined between the ice chest bottom and said horizontal deck;

supports under said horizontal deck for positioning said horizontal deck a distance above the ice chest bottom; and

a drain water suction pick up tube having a lower portion extending downwardly from said horizontal deck into said volume, said lower portion having an end which is spaced above the ice chest bottom during use.

18. The support structure of claim 17, wherein said drain water suction pick up tube has an upper portion which extends upwardly from said horizontal deck.

19. The support structure of claim 18, wherein said upper portion of said drain water suction pick up tube comprises a nipple to which a riser tube can be connected.

20. In combination:

a portable ice chest having a bottom, four walls and a top opening with a cover; and

an adjustable support structure comprising a horizontal deck for supporting food and ice within said ice chest above said ice chest bottom, a volume for melt water being defined between said ice chest bottom and said horizontal deck;

said horizontal deck including

a generally rectangular main portion having four side edges, and

a pair of adjustable wings extending past two adjacent side edges of said main portion;

supports under said main portion for positioning said horizontal deck a distance above said ice chest bottom;

a drain water suction pick up tube having a lower portion extending downwardly from said horizontal deck into said volume, said lower portion having an end which is spaced above the ice chest bottom during use, and said drain water suction pick up tube having an upper portion which extends upwardly from said horizontal deck;

a drain connection tube extending through one of said side walls of said ice chest near said top opening to facilitate connection to a suction device; and

a riser tube connected to said nipple, extending upwardly within said ice chest, and connected to said drain connection tube.
