Abstract
Abstract A leaf skimmer for swimming pools has a floating member placeable on the surface of water in the pool adjacent to and upstream of a water circulation drain of the pool. Attached to the floating member is a net immersed in the water for collecting debris in the proximity of the surface of the water in the pool. The floating member is preferably tethered to the side of the pool so as to be easily removable at predetermined intervals for dumping the debris from the net.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
208 words
A leaf skimmer for swimming and similar pools of water, comprising, in combination: (a) floating means for placement on a water surface adjacent to and upstream of a water circulating drain of an associated pool; and (b) screen means attached to the floating means and immersed in the water for collecting debris in the proximity of the surface of the water of the pool, the floating means including a framework comprising a plurality of sides surrounding and forming a hollow interior of the framework, the screen means being disposed extending beneath the sides of the framework and under the hollow interior, formed by the framework, the one of the sides of the framework forming an access opening to the hollow interior of the framework, with the screen means comprising a net attached to the one of the sides beneath the access opening formed thereby, and the one of the sides of the framework comprising a substantially U-shaped member having a bridge portion forming the access opening and a pair of legs permitting connection of the U-shaped member to connecting sides of the framework, the net being attached to the bridge portion and the legs being connected to sides of the framework joined with the one of the sides.
Claim 2
Dependent Claim
208 words
A leaf skimmer for swimming and similar pools of water, comprising, in combination: (a) floating means for placement on a water surface adjacent to and upstream of a water circulating drain of an associated pool; and (b) screen means attached to the floating means and immersed in the water for collecting debris in the proximity of the surface of the water of the pool, the floating means including a framework comprising a plurality of sides surrounding and forming a hollow interior of the framework, the screen means being disposed extending beneath the sides of the framework and under the hollow interior, formed by the framework, the one of the sides of the framework forming an access opening to the hollow interior of the framework, with the screen means comprising a net attached to the one of the sides beneath the access opening formed thereby, and the one of the sides of the framework comprising a substantially U-shaped member having a bridge portion forming the access opening and a pair of legs permitting connection of the U-shaped member to connecting sides of the framework, the net being attached to the bridge portion and the legs being connected to sides of the framework joined with the one of the sides.
Claim 3
Dependent Claim
37 words
A structure as defined in claim 1, wherein the sides joined with the one of the sides merge toward and join one another to form a framework in the form of a wedge when viewed in plan.
Claim 4
Dependent Claim
64 words
A structure as defined in claim 2, wherein the floating means includes three annular float elements, two of the float elements being arranged adjacent the legs of the U-shaped member and the third of the float elements being mounted on the sides joined with the U-shaped member where these sides join one another, the net being disposed surrounding the third of the float elements.
Claim 5
Dependent Claim
141 words
A leaf skimmer for swimming and similar pools of water, comprising, in combination: (a) floating means for placement on a water surface adjacent to and upstream of a water circulating drain of an associated pool; and (b) screen means attached to the floating means and immersed in the water for collecting debris in the proximity of the surface of the water of the pool, the floating means including a framework comprising a plurality of sides surrounding and forming a hollow interior of the framework, the screen means being disposed extending beneath the sides of the framework and under the hollow interior formed by the framework, with the floating means further including a plurality of float elements arranged on the framework for providing desired duoyancy to the framework, the screen means comprising a net disposed below and generally surrounding the float elements.
