Abstract: A portable security wall for isolating an area on the ground includes an enclosure wall comprised of a plurality of sections, a plurality of post members for mounting the wall on the ground, and a plurality of weighted post support members for supporting the post members. The wall can be made of separate rigid sections or, alternatively, a continuous flexible band with a plurality of longitudinally-spaced pockets for receiving the post members. The pockets define the sections of the wall. The wall can also be made of separate flexible sections which may be wound on or unwound from elongated shaft members by applying a rotary force, e.g., through use of a motor. The wall may be made tall to block the public's view of the area and two tall walls may be connected together to form a canopy.
