Abstract

A portable wall component is disclosed. The wall component comprises a pair of vertical posts. Each post has an upper component and a lower component with a hollow aperture extending therethrough. Each post also has a downwardly extending smaller cylindrical section at the bottom of the upper component and a complimentary cylindrical recess at the top of the lower post for receiving the smaller cylindrical section. An elastic band is located within each aperture extending along the length thereon and slightly beyond. A ring at the upper end of each upper component is coupled to the upper end of its associated band. A base component at the lower end of each lower component is coupled to the lower end of its associated band. A flexible sheet is provided with parallel upper and lower horizontal edges and parallel vertical end edges therebetween coupled to the posts. The flexible sheet has half-moon wind flaps cut therein and openings at the regions where the upper and lower components join.
