Abstract
Abstract A portable screen of fabric is held upright by a plurality of hollow poles clamped to the fabric by C clamps, preferably one the length of the pole. A stake is telescoped within each hollow pole, and held in an extended position (to adjust the height of the screen) by the friction of a resilient sleeve near the top of the stake, and additionally by a C clamp around the stake adjusted up against the pole. Straps are provided to secure the screen in a rolled up condition, and to carry the rolled up screen.
