A wire rod pedestal type chair base comprising:
- a hub assembly;
- and
- a plurality of wire rod support sets supporting said hub assembly, each set including a first rod element attached at one end to and extending laterally and generally horizontally outward from said hub assembly and a second rod element attached at one end to a portion of said assembly above the point at which the first rod is attached and extending diagonally downward therefrom;
- a caster socket assembly for each wire rod set secured to the other ends of said first and second wire rods for receiving casters whereby said base rests on the floor;
- said hub assembly including an inner tube and an outer tube which masks said inner tube, said first rod element extending through and being rigidly attached to said outer tube and said second rod element extending through and being secured to said outer tube, and abutting against said inner tube to provide support.

A wire rod, pedestal type chair base comprising:
- a hub assembly;
- a plurality of wire rod support sets supporting said hub assembly, each set including a first rod attached at one end to said hub assembly and extending laterally and generally horizontally outwardly from said hub assembly and a second rod attached at one end to said hub assembly at a point above said first rod and extending generally diagonally downwardly and outwardly therefrom;
- a caster socket assembly for each wire rod set including an elongated slot therein, the ends of each of said first and second wire rods being mounted immediately adjacent one another in said elongated slot.
A wire rod chair base comprising:
- a hub assembly;
- a plurality of wire rod support sets, each wire rod support set including a first rod element attached to and extending laterally and generally horizontally outward from a lower portion of said hub assembly and a second rod element attached to a higher portion of said hub assembly and extending diagonally downward therefrom;
- a caster socket means for adjoining and rigidly securing said first and second rod elements at their outer end portions from said hub assembly, said caster socket means further including adjustment means thereon for selectively raising and lowering a caster mounted therein relative to said ends of said rod elements;
- said caster socket means for adjoining and rigidly securing said wire rod elements at their outer end includes portions from said spindle upper and lower housings, said housings including a threaded portion therebetween to allow relative up and down movement of said housings with respect to each other, said lower housings including a slotted portion capable of receiving said first and second rod elements therein, and both of said portions including an aperture therein for slidably receiving casters of the like said aperture only partially extending through said upper housing and the top of the caster pintle engaging the top of said upper housing whereby when it is desired to raise and lower said rod elements with respect to said casters, said upper housing may be displaced with respect to the lower housing by rotating the upper housing with respect to the lower housing along the threaded portion therebetween so as to raise and lower said rod elements with respect to the casters.
