- 6. The table base according to claim 5, wherein the slip-in structural fitting further comprises a connector operable to connect the fitting to one of the tubes such that the end surface mates with the outer diameter of the tube.
- 7. The table base according to claim 5, wherein the base of the slip-in structural fitting has an outer diameter substantially the same as the outer diameter of the tube engaged by the engagement member.
- 8. The table base according to claim 5, wherein the engagement member comprises a pair of engagement fingers shaped to fit into the inner diameter of the tube engaged by the engagement member.
- 9. The table base according to claim 4, wherein at least one of the structural fittings comprises a slip-on fitting having an inner diameter greater than or equal to the outer diameter of one of the tubes.
- 10. The modular office cubicle system according to claim 9, wherein the slip-on structural fitting further comprises a set screw operable to press against the tube such that the fitting grips the tube.
- 11. A collapsible table base for supporting a table top in a generally horizontal position above a generally horizontal support surface, said table base comprising:
four spaced apart generally vertical legs each having a lower end configured to contact the support surface and an upper end, each of the legs having a height and an outer diameter; replaceable polymerized sheathing surrounding each of the legs, the sheathing having an inner diameter equal to or greater than the outer diameter of the legs; a plurality of spaced apart horizontal rails for supporting the table top, said horizontal rails interconnected with the upper ends of the legs, each of the horizontal rails having an outer diameter and a length; and replaceable polymerized sheathing surrounding each of the horizontal rails, the sheathing having an inner diameter equal to or greater than the outer diameter of the horizontal rails.
- 12. The table base according to claim 11, wherein said plurality of horizontal rails comprises:
a first pair of parallel spaced apart horizontal rails, each rail extending between the upper end of two of the vertical legs and having a first end and a second end; and a second pair of parallel spaced apart horizontal rails, one rail extending between the first ends of the first pair of horizontal rails and the other rail extending between the second ends of the first pair of horizontal rails.
- 13. The table base according to claim 11, further comprising a first leg brace extending between two of said legs between the lower and upper ends thereof, the leg brace having a first end interconnected with one leg and a second end interconnected with the other leg.
- 14. The table base according to claim 11, wherein the sheathing extends substantially the entire height of the legs and the entire length of the horizontal rails.
- 15. A collapsible table base for supporting a table top in a generally horizontal position above a generally horizontal support surface, said table base comprising:
four spaced apart generally vertical legs comprising a left front corner leg, a right front corner leg, a left rear corner leg, and a right rear corner leg, each of the legs having a lower end configured to contact the support surface and an upper end; a first pair of parallel spaced apart horizontal rails, one rail extending between the upper end of the left rear corner leg and the upper end of the left front corner leg, the other rail extending between the right rear corner leg and the right front corner leg, each of the rails having a front end and a rear end; a second pair of parallel spaced apart horizontal rails, one rail extending between the front ends of the first pair of horizontal rails and the other rail extending between the rear ends of the first pair of horizontal rails, each of the second pair of horizontal rails having a left end and right end; a first leg brace having a first end interconnected with the left rear leg brace between the upper and lower ends thereof and a second end interconnected with the left front leg brace between the upper and lower ends thereof, the first leg brace having a midportion between the first and second ends; and an extension portion having a horizontal member having ends interconnected with the left ends of the second pair of horizontal rails and a midportion therebetween, the extension portion further having a support member extending between the midportion of the first leg brace and the midportion of the horizontal member.
- 16. A collapsible table base for supporting a table top in a generally horizontal position above a generally horizontal support surface, said table base comprising:
a support portion comprising four spaced apart generally vertical legs comprising a left front corner leg, a right front corner leg, a left rear corner leg, and a right rear corner leg, each of the legs having a lower end configured to contact the support surface and an upper end; a horizontal top portion supported by the support portion, the top portion comprising a first pair of parallel spaced apart horizontal rails, one rail extending between the upper end of the left rear corner leg and the upper end of the left front corner leg, the other rail extending between the right rear corner leg and the right front corner leg, each of the rails having a front end and a rear end disposed outboard of the legs; and a perimeter rail system interconnected with the front and rear ends of the horizontal rails and defining the outer perimeter of the table base, the perimeter rail system and the horizontal top portion being disposed in a generally horizontal plane.
- 17. A collapsible table base for supporting a table top in a generally horizontal position above a generally horizontal floor, said table base comprising:
a plurality of generally vertical leg members having lower ends configured to contact the floor and upper ends spaced therefrom; a plurality of triangular structures each having a base member and a pair of side members interconnected with structural fittings so as to define a generally triangular shape, each of the side members of the triangular structures being interconnected with the upper end of one of the legs, the triangular structures being supported by the legs such that the bases are disposed in a generally horizontal plane with the side members angling downwardly therefrom; and a plurality of releasable structural fittings removably interconnecting the leg members with the triangular structures so as to form a generally rigid base.
