发明名称 Pool cover weight
摘要 A pool cover weight comprising an elongated flexible tubular member which is filled with a ballast material and which has a tether secured thereto so that a plurality of the weights may be placed over the side edge portions of a pool cover extending over an above-ground pool with the tethers thereof being secured to the upper ends of the side walls of the pool. The positioning of the pool cover weights on the pool cover prevent the pool cover from flapping in the wind.
