Abstract

A support for stools or tables is formed from two identical hollow plastic sections. The sections are generally conical in shape so that they can fit inside each other for stacking purposes when not in use. The smaller end of each section is provided with interlocking means so that the sections may be releasably secured together to form a stool or support for a table.

Claims

1. Furniture of the class described comprising a pair of identical truncated conical sections including a circular lower base and a smaller parallel upper base formed from a thin plastic sheet material, each section having two upwardly extending, upwardly tapered projections and two downwardly extending, downwardly tapered recesses, said projections extending above the small base of the truncated conical section, said projections and recesses dividing each section into four equal parts, said projections and recesses diametrically opposite to each other and generating thereby a coaxial upwardly tapered truncated cone in each section, said truncated cone having an upper support surface concentric with the conical section in a plane parallel to the circular lower base at least closely adjacent to the plane of the small upper base of the conical section whereby in assembled relationship, the projections on one section fit into the recesses on the other section with the upper support surfaces of each upwardly tapered truncated cone facing and closely adjacent to each other when no weight is on the furniture, said upper support surfaces abutting each other when weight on the furniture causes a controlled deformation of the sections, to form a centrally disposed abutment support inside the assembled section whereby the sections can carry greater weight.

2. The furniture described in claim 1, including a cover fitting over the large end of the assembled sections to form a stool.

3. The furniture described in claim 1 including a square cover fitting over the end of a section to form a table.

4. The furniture described in claim 1 including a spacer, said spacer having projections and recesses at each end, said projections and recesses identical in shape to the projections and recesses on each section whereby the spacers can be inserted between the sections to vary the height of the furniture.

5. The furniture described in claim 2 wherein the cover has a back support so the furniture can function as a bar stool.

6. The furniture described in claim 1 wherein the sections are stackable in telescopic relationship with the projections of one section fitting into the recesses of the other.

7. The furniture described in claim 1 including a square cover fitting over the end of a section to form a table.
