Abstract
Abstract A pool water-conditioning system for installation in an abovethe-ground swimming pool is capable of withdrawing water from the pool through an outlet opening near the top of the pool and one near the bottom of the pool, through each exclusively or through both simultaneously, and of reintroducing the water into the pool through an inlet opening near the top and one near the bottom, through each exclusively or through both simultaneously. The wall of the pool can be constructed with a panel element that is interchangeable with other panel elements, each of which has preformed openings for receiving the components of the pool cleaning system.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
375 words
An above-the-ground swimming pool comprising a structural pool wall panel having a first pair of openings therein located generally one above the other on a first generally vertical center line, one such opening being adjacent the top of the panel, and the other being adjacent the bottom of the panel, and a second pair of openings located generally one above the other on a second generally vertical center line spaced laterally from the first center line, one of the second openings being located adjacent the top of the panel and the other opening being located generally adjacent the bottom of the panel, a skimmer mounted at the top opening of the first pair to receive water with-drawn from the top of the pool, conduit means associated with the first pair of openings for receiving water from the pool through said first pair of openings, pool water conditioning means coupled to said first conduit means to receive water therefrom, said first conduit means including a common branch connected to the pool water conditioning means, a first branch connected from the common branch and to an outlet from the skimmer and a second branch connected from the common branch to the lower opening of the first pair, first valve mean for selectively proportioning the flow of pool water through the first and second branches of said first conduit means selectively to withdraw water from the pool through each of the first pair of openings individually or through both of said first pair of openings simultaneously in an infinitely variable proportion, second conduit means connected to the pool conditioning means for returning water therefrom to the pool through the second pair of openings and including a common branch connected to said pool water conditioning means, a first branch connected to the upper opening of the second pair and second branch connected to the lower opening of The second pair, and second valve means for selectively proportioning the flow of water through the first and second branches of said second conduit means selectively to return water to the pool from the pool water conditioning means through each of said second pair of openings individually or through both of said second pair of openings simultaneously in an infinitely variable proportion.
Claim 2
Dependent Claim
375 words
An above-the-ground swimming pool comprising a structural pool wall panel having a first pair of openings therein located generally one above the other on a first generally vertical center line, one such opening being adjacent the top of the panel, and the other being adjacent the bottom of the panel, and a second pair of openings located generally one above the other on a second generally vertical center line spaced laterally from the first center line, one of the second openings being located adjacent the top of the panel and the other opening being located generally adjacent the bottom of the panel, a skimmer mounted at the top opening of the first pair to receive water with-drawn from the top of the pool, conduit means associated with the first pair of openings for receiving water from the pool through said first pair of openings, pool water conditioning means coupled to said first conduit means to receive water therefrom, said first conduit means including a common branch connected to the pool water conditioning means, a first branch connected from the common branch and to an outlet from the skimmer and a second branch connected from the common branch to the lower opening of the first pair, first valve mean for selectively proportioning the flow of pool water through the first and second branches of said first conduit means selectively to withdraw water from the pool through each of the first pair of openings individually or through both of said first pair of openings simultaneously in an infinitely variable proportion, second conduit means connected to the pool conditioning means for returning water therefrom to the pool through the second pair of openings and including a common branch connected to said pool water conditioning means, a first branch connected to the upper opening of the second pair and second branch connected to the lower opening of The second pair, and second valve means for selectively proportioning the flow of water through the first and second branches of said second conduit means selectively to return water to the pool from the pool water conditioning means through each of said second pair of openings individually or through both of said second pair of openings simultaneously in an infinitely variable proportion.
Claim 3
Dependent Claim
47 words
An above-the-ground swimming pool in accordance with claim 1 wherein each of said first and second valve means is a single three-way flow proportioning valve located at the juncture between the common branch and the first and second branches of the respective first and second conduit means.
Claim 4
Dependent Claim
42 words
An above-the-ground swimming pool according to claim 2 wherein said first and second branches of both of said first and second conduit means are axially aligned, and wherein the common branches of both said first and second conduit means are axially aligned.
Claim 5
Dependent Claim
95 words
An above-the-ground swimming pool in accordance with claim 1 wherein a flexible hose extends into the pool and one end of the hose is connected to the inlet conduit located near thebot of the pool wall, whereby the hose oscillates back and forth when water at a sufficient velocity flows into the pool through the hose, thereby agitating dirt lying on the bottom of the pool, the inlet valve means regulating the amount of water flowing into the pool through the flexible hose in relation to the total amount of water flowing into the pool.
Claim 6
Dependent Claim
112 words
An above-the-ground swimming pool in accordance with claim 1 and further comprising chlorinating means, said chlorinating means including a porous container with at least one compartment disposed in one of the conduits of the first conduit and thus in the path of flow of the withdrawn water, the compartment being capable of receiving a quantity of chlorine dissolvable by the water. 6.An above-the-ground swimming pool in accordance with claim 5 wherein the chlorinating means includes a receptacle disposed in the skimmer housing below the normal water level therein and in communication with the water passing through the skimmer housing, and at least one body of slow-dissolving, chlorine-containing material received in the receptacle.
