Abstract

A molded, plastic support having an upper end and a lower end. The upper end has an outer profile and is molded to have a pair of intersecting, rectangular slots formed therein. The lower end has an outer profile greater than the outer profile of the upper end, wherein the support tapers outwardly from the upper end to the lower end. The support is hollow, and the lower end is open to expose a hollow inner cavity. The support has a height of at least 20 inches.

Claims

1. A molded, plastic support having an upper end and a lower end, said upper end having an outer profile and being molded to have a pair of intersecting, mutually perpendicular, rectangular slots formed therein, said lower end having an outer profile greater than said outer profile of said upper end, wherein said support tapers outwardly from said upper end to said lower end, said support being formed to have a generally uniform wall thickness and said lower end being open to expose a hollow inner cavity, wherein said support is stackable onto another like support, said support having a height of at least 20 inches.

2. A molded, plastic support as defined in claim 1, wherein said support is formed to be symmetrical about a central axis extending through said support from said upper end to said lower end.

3. A molded, plastic support as defined in claim 1, wherein said support is pyramidal in shape.

4. A molded, plastic support as defined in claim 1, wherein said support is conical in shape.

5. A molded, plastic support as defined in claim 1, wherein said support is injection molded to have a generally uniform wall thickness.

6. A molded, plastic support as defined in claim 1, further comprising a molded polymer base section dimensioned to attach to said lower end of said support, said base section having an outer surface profile conforming to the outer profile of the lower end of said support, and said base section having a cavity formed therein, said cavity in said base section communicating with said hollow inner cavity in said support when said base section is attached to said support, said cavity in said base section defining space for weights to stabilize said support and base section.

7. A molded, plastic support as defined in claim 1, wherein said support is formed of a thermoplastic.

8. A molded, plastic support as defined in claim 7, wherein said support is injection molded.

9. A molded, plastic support as defined in claim 7, wherein said thermoplastic is polyolefin.

10. A molded, plastic support as defined in claim 9, wherein said polyolefin is polyethylene or polypropylene.

11. A molded, plastic support as defined in claim 7, wherein said thermoplastic is a filled thermoplastic.

12. A molded, plastic support as defined in claim 11, wherein.said filled thermoplastic includes a colorant.

13. A molded, plastic support having a generally pyramidal shape with a truncated upper end, a pair of intersecting rectangular slots formed in said upper end, said support having a generally uniform wall thickness and being open at a lower end to define a hollow inner cavity wherein said support is stackable onto another like support.

14. A molded, plastic support as defined in claim 13, wherein said slots are mutually perpendicular and measure at least 1½

inches in width and 3½

inches in depth.

15. A molded, plastic support as defined in claim 14, wherein said support is injection molded.

16. A molded, plastic support as defined in claim 14, wherein said support is formed of a thermoplastic.
