Abstract
Abstract This invention pertains to a swimming pool system wherein a plurality of flexible conductors, preferably of extruded plastic, is provided with small apertures formed in their sidewalls. These outlets provide means for forming directed jet streams of water delivered through said conductors from a pressurized supply. The jets are directed against the bottom of the pool so as to stir up dirt and debris tending to accumulate on the bottom of the pool. This swimming pool cleaning system contemplates that extruded vinyl or like flexible tubing have a flat bottom to which is applied a contact adhesive adapted to retain the tubing on the bottom of the pool whether the pool is of concrete or is made with a plastic lining. Being flexible the conductors may be arranged on the bottom of the pool in any desired order so as to agitate natural silt accumulations. The extrusions shown are more or less semicircular and may be either a single or double channel and in one embodiment is formed with an extending wing disposed to deflect the water downwardly. The jet nozzles may be only small holes or may also be short tubes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
235 words
In a swimming pool cleaning system wherein the silt is agitated by jet streams of pressurized water directed against the wall and the floor of the pool, said cleaning system including: (a) a header member adapted to receive a supply of pressurized water and to transport said pressurized water; (b) at least two fluid conductors connected to the header member so as to receive a determined portion of the pressurized water and to conduit said water therethrough, said conductors being made of a flexible plastic and being formed so as to have a substantially flat bottom portion and with a cover member extending from the bottom portion to provide a passageway through along the conductor; (c) a self-stick adhesive applied to the outer face surface of the flat bottom portion, the adhesive adapted to retain the conductor to and on the inner surface of the pool when the flat surface of the conductor is pressed thereagainst, and (d) a multiplicity of small apertures formed in the cover member, said apertures disposed and extending through the wall of the cover member so that pressurized water as it is discharged from the aperture will act as a jet stream and its orientation is such that it will tend to flow toward the plane of the flat surface of the bottom portion of the conductor when the conductor is in attached condition on the surface of the pool.
Claim 2
Dependent Claim
235 words
In a swimming pool cleaning system wherein the silt is agitated by jet streams of pressurized water directed against the wall and the floor of the pool, said cleaning system including: (a) a header member adapted to receive a supply of pressurized water and to transport said pressurized water; (b) at least two fluid conductors connected to the header member so as to receive a determined portion of the pressurized water and to conduit said water therethrough, said conductors being made of a flexible plastic and being formed so as to have a substantially flat bottom portion and with a cover member extending from the bottom portion to provide a passageway through along the conductor; (c) a self-stick adhesive applied to the outer face surface of the flat bottom portion, the adhesive adapted to retain the conductor to and on the inner surface of the pool when the flat surface of the conductor is pressed thereagainst, and (d) a multiplicity of small apertures formed in the cover member, said apertures disposed and extending through the wall of the cover member so that pressurized water as it is discharged from the aperture will act as a jet stream and its orientation is such that it will tend to flow toward the plane of the flat surface of the bottom portion of the conductor when the conductor is in attached condition on the surface of the pool.
Claim 3
Dependent Claim
21 words
A swimming pool cleaning system as a claim 1 in which the fluid conductors are of extruded plastic such as vinyl.
Claim 4
Dependent Claim
30 words
A swimming pool cleaning system as claim 2 in which the conductor is formed to provide a single passageway and the cover member is formed as an integral arcuate member.
Claim 5
Dependent Claim
76 words
A swimming pool cleaning system as in claim 3 in which the cover member is formed with at least one wing member which extends outwardly from the side portion of the cover member, said wing member disposed to act as a downward deflector for a jet stream of water exiting from the aperture formed in the cover member, said aperture disposed in the sidewall portion of the cover member intermediate the wing and the flat bottom.
Claim 6
Dependent Claim
50 words
A swimming pool cleaning system as in claim 2 in which the conductor is formed to provide two separate fluid passageways and in which there are apertures formed in the oppositely disposed sidewalls of the cover member so that jet streams are discharged from opposite sides of the cover member.
Claim 7
Dependent Claim
24 words
A swimming pool cleaning system as in claim 2 in which the overall height of the plastic extrusion is not more than an inch.
Claim 8
Dependent Claim
27 words
A swimming pool cleaning system as in claim 1 in which the diameter of the apertures providing the jet stream is less than ten-thousandths of an inch.
Claim 9
Dependent Claim
42 words
A swimming pool cleaning system as in claim 1 in which at least some of the aperatures in the cover member have short lengths of small tubing connected thereto so as to provide directed flow of the jet streams of pressurized water.
Claim 10
Dependent Claim
38 words
A swimming pool cleaning system as in claim 1 in which the header member has at least three like length conductors attached thereto, each conductor having a spaced series of apertures along each side of its cover member.
Claim 11
Dependent Claim
174 words
The words-In a swimming pool cleaning system wherein the silt is agitated by jet streams of pressurized water directed against the wall and the floor of the pool, said cleaning system including: a fluid conductor made as an extruded tube of flexible plastic such as vinyl, the extrusion being shaped so as to provide a substantially flat bottom portion from which a cover member extends to provide a tubular passageway through and along the conductor; a self-stick adhesive applied to the outer face surface of the flat bottom portion, said self-stick adhesive adapted to retain the conductor to and on an inner surface of a pool when the flat surface of the conductor is pressed thereagainst, and a series of small apertures formed in the cover member, the aperture being shaped and oriented in the sidewall of the cOver member so that pressurized water as it is discharged from the aperture will tend to flow in a path adjacent to the plane of the flat surface of the attached bottom portion of the conductor.
