Abstract
Abstract A collapsible stand for an upright vertical support is the subject of this invention. A U-shaped bracket holds a roller and is mounted on a telescoping stanchion by use of a set screw in the collar of the bracket. The stanchion is in turn supported by a stand, the base portion of which comprises three legs which are bolted to two horizontal plates positioned one above the other. The lower plate is larger than the upper plate and thereby determines the angle of disposition of the legs. The stand is collapsible by disengaging the legs from the plates and dismounting the bracket and roller assembly from the stanchion.
