发明名称 SWIMMING POOL SKIMMER COVER
摘要 A skimmer cover assembly includes a cover that is adapted to fit over the face flange of the skimmer or pool wall to prevent water from entering the skimmer assembly. The cover is secured to the skimmer by use of a draw bolt that is threaded at one end and includes a thumb screw or wing nut at a second end. The threaded end is adapted to be threaded into a support brace that is braced against an inside surface of the skimmer housing or to the skimmer housing itself. Tightening the draw bolt with the thumb screw draws the cover tightly against the face flange of the skimmer. The cover includes a gasket seal about its perimeter to form a watertight seal with the face flange of the skimmer. The draw bolt also has an o-ring that is positioned between the thumb screw and the cover to prevent water from leaking past the cover.
