Abstract: A wind screen device for an outdoor grill is provided, which comprises a horizontal bottom plate and a series of vertical side plates. The vertical side plates contact each other and the bottom plate to form an enclosure or windscreen. The enclosure is capable of housing a variety of types and sizes of outdoor cooking units, thereby screening out the wind from the outdoor cooking unit. The rigid plates are hooked together by split rings, which are threaded through slotted holes located near the edges of the plates. The side plates are held in place by angled clips when the windscreen device is assembled. The side plates are also capable of being alternately folded down with all of the plates stacked together for storage. The windscreen device includes an additional opening in one of its side plates, which is designed to admit a gas hose therethrough.
