Abstract
Abstract A water deflector assembly characterized by an elongated water deflector, and an adaptor block which couples the water deflector to a pre-existing skimmer provided in the sidewall of a swimming pool. The adaptor block allows a standardized deflector to be attached to a number of different skimmer brands. The water deflector includes an elongated central portion and two oppositely deflected end portions, and is designed to minimize eddy currents and maximize the amount of water deflected towards the skimmer for a given deflector length.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
A water deflector assembly for deflecting water towards a skimmer provided in the wall of a swimming pool, the water deflector comprising: (a) an adaptor block; (b) means coupling said adaptor block proximate to said skimmer; (c) an elongated water deflector having a substantially planar central portion, a first end portion angularly deflected from said central portion, and a second end portion angularly deflected from said central portion in a second direction substantially opposite said first direction, where said first end portion and said second end portion are substantially planar and parallel; and (d) means attaching said first end portion to said adaptor block such that said second end portion is substantially parallel to said skimmer, and such that an upper surface of said deflector protrudes above the surface of the water within said pool.
Claim 2
Dependent Claim
135 words
A water deflector assembly for deflecting water towards a skimmer provided in the wall of a swimming pool, the water deflector comprising: (a) an adaptor block; (b) means coupling said adaptor block proximate to said skimmer; (c) an elongated water deflector having a substantially planar central portion, a first end portion angularly deflected from said central portion, and a second end portion angularly deflected from said central portion in a second direction substantially opposite said first direction, where said first end portion and said second end portion are substantially planar and parallel; and (d) means attaching said first end portion to said adaptor block such that said second end portion is substantially parallel to said skimmer, and such that an upper surface of said deflector protrudes above the surface of the water within said pool.
Claim 3
Dependent Claim
30 words
A water deflector assembly as recited in claim 1 wherein the angle between said first end portion and said central portion is within the range of 30° and 60°, inclusive.
Claim 4
Dependent Claim
36 words
A water deflector assembly as recited in claim 2 wherein said adaptor block is substantially a rectangular prism provided with a first pair of spaced apart bores, and a second pair of spaced apart, threaded bores.
Claim 5
Dependent Claim
53 words
A water deflector assembly as recited in claim 3 wherein said first pair of spaced apart bores are receptive to fasteners which attach said adaptor block to said swimming pool wall, and said second pair of spaced apart, threaded bores are receptive to a pair of fasteners engaged with said first end portion.
Claim 6
Dependent Claim
31 words
A water deflector assembly as recited in claim 1 wherein said water deflector assembly has a specific gravity greater than that of the water within said pool and thus cannot float.
