ABSTRACT:
A chair base connection assembly for connecting a pipestand to a chair base includes an outer sleeve having opposing flared ends, an inner sleeve having a tapered inner diameter for engaging the pipestand and an outer surface having a taper at an upper end for engaging an inner flared surface at the upper end of the outer sleeve and external threads at the lower end for engaging a tapered intermediate nut having an outer flared surface which engages an inner flared surface on the lower end of the outer sleeve. The chair base connection assembly of this invention provides a stable, strong, wobble-free connection between the base and the pipestand, while allowing greater dimensional variability of the components comprising the chair base connection assembly, thereby reducing the manufacturing costs.
