摘要：A portable sign stand comprises a mast for supporting an article (preferably asign) thereon and a plurality of support legs for supporting the mast. A heart plateassembly comprises a heart plate for pivotally receiving and attaching to top ends of
each of the plurality of support legs and a center tube having a hollow interior forslidably receiving the inner mast. The center tube extends upwardly a predetermineddistance from a top edge of the heart plate. This predetermined distance is at least twoinches in order to protect a user's fingers in the event of an inadvertent or intentionaldropping of the inner mast downwardly through the hollow interior of the center tube toits minimum height position. In the most preferred embodiments, the minimumpredetermined distance is at least about four inches, because this distance permits anaverage user's hand to be entirely wrapped about the center tube without the risk of apinch injury if the mast is suddenly dropped to its minimum height position.
