发明名称 A POOL SKIMMER
摘要 The invention relates to a pool skimmer including first and second tubular members that are telescopically displaceable with respect to one another, flotation means for suspending it substantially vertically in a body of water, and a tubular connector mounted on the second tubular member in liquid communication with a space defined within the tubular members and defining connector formations for connecting it in line with a hose of a pool pump. In operation in a body of water, the pump creates suction in the tubular connector and surface water flows via a weir defined by the top of the first tubular member, into the said space, via the tubular connector, and into the pool hose. The tubular members define in their side walls apertures that increasingly come into register as overlap of the members increase, thereby permitting water to flow via the apertures directly into the said space.
