Abstract
Abstract An elongated buoyant member having laterally angled inner and outer ends. A flat upstream face is provided by an elongated strip affixed to one side of the member and having an inner end angled outwardly from the angled inner end of the member. The strip is slightly flexible so as to vary the angle of the inner end for an accommodation of variously shaped skimmer boxes. A decorative weight is tied to the trap through an elongated cordlike member for a positioning of the trap and a clip-on auxiliary screen is provided to selectively give a greater operative depth to the trap.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
232 words
For use in conjunction with a pool skimmer or like disposal means, a trap positionable in outwardly projecting relation from a skimmer into a water flow path, said trap including an elongated buoyant member having an upstream flow intercepting side, said buoyant member including integral inner and outer ends, the inner end of the buoyant member being angularly orientated and engageable against a pool side adjacent a skimmer whereby said buoyant member projects into the pool at an angle determined by the angular orientation of the inner end, a striplike member affixed to the buoyant member adjacent the inner end thereof, said strip-like member angling away from the buoyant member in an opposite direction from the inner end of the buoyant member for reception within a skimmer box, the box engaging strip-like member cooperating with the pool side engaging inner end of the buoyant member to position the trap, means for releasably retaining said buoyant member in position within a pool, said strip-like member being flat and extending and presenting a flat face along substantially the entire upstream side of the buoyant member, and an elongated vertically arcuate shield positionable along said buoyant member and depending therebelow, said shield including clip means thereon selectively receivable over the buoyant member for an attachment of the shield thereto, said shield being of a depth sufficient so as to project below said flat strip-like member.
Claim 2
Dependent Claim
