Abstract

Abstract A collapsible support stand is disclosed which has two sets of opposing legs extending radially from a hollow cylindrical hub support. The stand may be collapsed to a closed position where adjacent legs are substantially parallel or to an open position where adjacent legs are substantially perpendicular to one another. A pair of opposing legs form an integral unit with a hollow cylindrical center joining the two legs. Each of the remaining opposing legs form upper and lower circular collars, which fit about the upper and lower ends of the cylinder. The caps are secured about the circular collars to hold them in place and secure the stand while allowing the pivotal movement.
