Abstract: A removable support assembly for a collapsible golf bag of the type having an open top cuff, a closed bottom cuff and a pliable intermediate back portion connecting the two cuffs. The removable support assembly comprises a base slidable into the bottom cuff. The base is dimensioned and configured so as to be held within the bottom cuff against any substantial lateral displacement. The support assembly further comprises an upper brace removably attachable to the upper cuff of the golf bag, and a supporting shaft connected to the base at one end and to the upper brace at the opposite end for keeping the collapsible golf bag upright. The supporting shaft is threaded at one end to provide a means for adjusting the effective length of the supporting assembly and is spring loaded at the opposite end to keep the pliable intermediate portion of the bag in a taut wrinkle free condition.
