|20090293352||Trellis - A trellis is disclosed. The trellis has a base, spaced flexible arms rising generally vertically upwardly and outwardly from the base to free ends, and two spacers. There are openings in each of the spacers in which the arms of the trellis are slidable. The walls of the openings in the spacers engage the flexible arms frictionally, exerting a force which opposes sliding movement of the spacers relative to the flexible arms.||12-03-2009|
