ABSTRACT:
The invention provides a debris diverting boom for use in diverting debris floating on the surface of a body of water toward a side skimmer opening thereof to facilitate its removal before it becomes waterlogged and sinks to the bottom. The body of the boom takes the form of a hollow cylindrical elongated body portion and an integral downwardly-extending skirt portion preferably produced by roll-forming from a narrow elongated strip of metal. The interior of the hollow body portion is filled with a tubular piece of closed-cell foam to provide the necessary buoyancy. The lower edge of the skirt is folded over to hide the raw metal edge and crimped to a regular pattern to increase its rigidity and to hide the random wrinkling of the material created by the folding process. The tube and skirt ends are covered with plastic caps for the same purpose. Alternatively, the boom is formed from plastic material by extrusion or foaming. A bracket to hold the boom at the required angle to the side of the pool or tank consists of an elongated rod having at both ends respective sets, each of at least two longitudinally-spaced, parallel, downwardly extending rods which extend through corresponding spaced vertical holes in the boom and the pool side. These prevent the boom and the bracket from rotating in the horizontal plane, and yet provide for vertical movement of the boom on the bracket; the rod is not too stiff so as to provide a certain amount of "spring" if the boom is impacted by a swimmer.
