Abstract
Abstract A portable, sun and wind shield having a flexible covering material and a collapsible frame for supporting said covering material is disclosed. The collapsible frame is comprised of at least two resilient support members secured at their respective ends by connecting means. An adjustable tensioning means is secured at the connecting means and is adapted to draw together the ends of the resilient support. The covering material is spanned between the resilient support members such that when the resilient support ends are drawn together and rotated in opposite direction about the connecting means, the covering material becomes tautly stretched.
