Abstract
Abstract An automatic cleaning system for swimming pools connected to a source of fluid pressure and having a control system for allowing fluid to escape through the jets in predetermined cycles is provided. The cycling of the jets provides a sweeping action across the inner surface of the pool so that debris and sediment are progressively moved to the pool drain opening. The jets are used in conjunction with a fluid manifold system which permits the cycling to be accomplished. The fluid manifold system is conveniently fixed to the inner surface of existing pools near the water level and adjacent to the coping, or an in ground manifold system may be used in conjunction with in place wall fittings as in the case of new pool construction. The jets may be of an adjustable nature and may remain in a fixed position or allowed to oscillate. By adjusting and angling the jets, predesigned current patterns are developed so that dirt and other debris is dislodged from the inner surface of the pool and carried or moved to the main drain. The jets are adjustable so that the current patterns from the jet may effect the cleaning of the pool of any configuration. A debris collection trap for placement over the drain is also provided. This trap permits removal of larger debris, thereby preventing it from obscuring or blocking the main drain.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
155 words
In a pool cleaning system, a pool structure having an inner surface, a plurality of jet means on said inner surface disposed for directing fluid to said inner surface thereby moving any debris and sediment, a source of fluid under pressure, and, control system means for directing fluid from said source of fluid under pressure selectively to alternate ones of said plurality of jet means so as to sweep said debris and sediment toward and into said drain opening under the action of said plurality of jet means, further including larger debris collection means for preventing larger debris such as leaves from entering said drain opening, said larger debris collection means permitting periodic removal of larger debris collected therein, wherein said larger debris collection means comprises a selectively closeable container positionable over said drain opening and having means for receiving debris and returning larger debris therein while allowing smaller debris and sediment to pass therethrough.
Claim 2
Dependent Claim
155 words
In a pool cleaning system, a pool structure having an inner surface, a plurality of jet means on said inner surface disposed for directing fluid to said inner surface thereby moving any debris and sediment, a source of fluid under pressure, and, control system means for directing fluid from said source of fluid under pressure selectively to alternate ones of said plurality of jet means so as to sweep said debris and sediment toward and into said drain opening under the action of said plurality of jet means, further including larger debris collection means for preventing larger debris such as leaves from entering said drain opening, said larger debris collection means permitting periodic removal of larger debris collected therein, wherein said larger debris collection means comprises a selectively closeable container positionable over said drain opening and having means for receiving debris and returning larger debris therein while allowing smaller debris and sediment to pass therethrough.
Claim 3
Dependent Claim
221 words
In a pool cleaning system, a pool structure having an inner surface, a drain opening in said inner surface, a plurality of jet nozzles in spaced relation on said inner surface disposed for directing fluid to said inner surface thereby moving any debris and sediment, a source of fluid under pressure, and, control system means for directing fluid from said source of fluid under pressure selectively to alternate ones of said plurality of jet nozzles so as to sweep said debris and sediment toward and into said drain opening under the action of said plurality of jet nozzles, wherein the number and location and direction of a first group of said jet nozzles are such that sediment and debris are swept by a first one of said plurality of jet means into the path of a second one of said plurality of jet nozzles, and such alternate sweeping continues in a zig-zag direction from an end of said pool structure removed from said drain opening toward said drain opening until said sediment and debris has reached the vicinity of said drain opening, and wherein the number, location, and direction of a second group of said jet nozzles are such as to impart a spiral motion to the sediment and debris, thereby causing said sediment and debris to enter said drain opening.
Claim 4
Dependent Claim
221 words
In a pool cleaning system, a pool structure having an inner surface, a drain opening in said inner surface, a plurality of jet nozzles in spaced relation on said inner surface disposed for directing fluid to said inner surface thereby moving any debris and sediment, a source of fluid under pressure, and, control system means for directing fluid from said source of fluid under pressure selectively to alternate ones of said plurality of jet nozzles so as to sweep said debris and sediment toward and into said drain opening under the action of said plurality of jet nozzles, wherein the number and location and direction of a first group of said jet nozzles are such that sediment and debris are swept by a first one of said plurality of jet means into the path of a second one of said plurality of jet nozzles, and such alternate sweeping continues in a zig-zag direction from an end of said pool structure removed from said drain opening toward said drain opening until said sediment and debris has reached the vicinity of said drain opening, and wherein the number, location, and direction of a second group of said jet nozzles are such as to impart a spiral motion to the sediment and debris, thereby causing said sediment and debris to enter said drain opening.
Claim 5
Dependent Claim
60 words
The invention of claim 1 wherein said pool defines said inner surface by means of generally vertical side walls joined by a generally horizontal bottom wall, said jets are located on said generally vertical side walls, and wherein said first group of jet nozzles are directed to impinge on said bottom wall so as to sweep sediment and debris thereon.
Claim 6
Dependent Claim
26 words
The invention of claim 3 wherein said pool defines a peripheral edge and wherein said jet nozzles are located in spaced relation around said peripheral edge.
Claim 7
Dependent Claim
18 words
The invention of claim 2 further including conduit means intercommuncating said jet nozzles with said control system means.
Claim 8
Dependent Claim
34 words
The invention of claim 5 wherein said conduit means comprises a manifold including a plurality of conduits and wherein said jet nozzles are in communication with a respective one of said plurality of conduits.
Claim 9
Dependent Claim
21 words
The invention of claim 6 wherein said conduit is a generally elongated member having a plurality of longitudinally oriented passages therein.
Claim 10
Dependent Claim
16 words
The invention of claim 7 further including means for mounting said manifold on said inner surface.
