发明名称 SWIMMING POOL LEAF TRAP
摘要 A portable leaf trap for use with swimming pools comprising a dome-like housing, perforate means affixed to the housing, a flexible base member extending outwardly from the housing, and lift means. An opening is provided in the side of the housing to provide communication between the outside of the housing and an interior defined by the perforate means and the housing inner surface. The leaf trap is adapted to be positioned over a swimming pool drain upon the floor of the pool with leaves and the like entering the trap interior through said opening. The lifting element is affixed to the perforate means in the vicinity of said opening and offset with respect to the center of gravity of the trap. When an upwardly directed force is applied to the lifting element, the leaf trap tends to pivot therearound thus trapping the leaves and the like within the interior at a location remote from said opening.
