  • Patent number: 5667175
    Abstract: A portable sign stand has a tripod frame in which one leg carries a self-adjusting bracket that urges a rigid sign upward against a pair of buttons near the top of the frame. The two other legs of the tripod are linked to one another and to an upright extension member that is connected to the leg carrying the bracket. Another pair of buttons connected to a plate of the bracket support a bottom corner or edge of the sign for being moved upward and held in position. The bracket is forced upward into position by an elastic cord. Legs of the tripod are made of square aluminum tubing. The bracket also carries an upright receptacle into which a mast of a roll-up may be placed and supported without use of buttons. Provisions are made for carrying various types of signs in different positions, depending on wind conditions and other factors.
