Abstract: A hollow inflatable barrier for sports games formed of flexible air impervious material is supported on a generally flat surface to form a continuous configuration of sufficient size and shape to surround the perimeter of a game playing area. A fan or blower connected by a conduit in fluid communication with the hollow barrier conducts air into the hollow barrier to inflate it. In the inflated condition the barrier forms a perimeter barrier surrounding the game playing area to bar passage of small objects traveling across the generally flat surface. In a preferred embodiment the inflatable barrier is formed of a plurality of elongate hollow tubular members releasably joined end-to-end to form the continuous configuration. The tubular members may be provided in various shapes including straight for forming straight sections of the barrier, and straight with angled ends or curved for forming the corners of the barrier.
