Pool-cleaning apparatus

Claim 2

A swimming pool cleaning apparatus, comprising: a manually portable and readily movable weight means adapted to sink in water; said weight means having horizontally disposed structure, the maximum dimensions of which equal a small fraction of the length or breadth of a swimming pool; said weight means being adapted to be manually moved and temporarily located in various desired positions relative to the sides and ends of a swimming pool and on the bottom of said swimming pool; said weight means having supporting surface means adapted frictionally to engage the bottom of a swimming pool; said supporting surface means being the only means for holding said weight means stationarily on the bottom of a swimming pool; a plurality of elongated flexible jet reactive pool cleaning tubes coupled to said weight means at an elevation above said supporting surface so as to dispose a major portion of their length engageable with the bottom of said pool; said pool cleaning tubes substantially equally spaced apart and extending generally radially away from said weight means and having a major portion of said length thereof disposed for engagement with the bottom of a pool when said weight means is supported on said bottom of said pool by said supporting surface means; a flexible water delivery conduit coupled to said weight means and adapted to contain water under pressure in communication with said jet reactive pool cleaning tubes; said jet reactive pool cleaning tubes communicating said water delivery conduit and adapted to receive water under pressure therefrom; said jet reactive tubes each having free and open jet end means substantially spaced from said weight means and adapted to issue a jet of water therefrom and to thereby cause sinuous movement of said pool cleaning tubes relative to said weight means and relative to the bottom and sides of said swimming pool; said weight means being of sufficient magnitude to hold said supporting surface means down in frictionally engaged stationary relationship with the bottom of said pool so that said weight means resists jet reaction forces imposed by said jet reactive pool cleaning tubes whereby said weight means remains stationary on the bottom of said pool while sinuous movement of said jet reactive pool cleaning tubes continues to operate in a manually preselected area around said weight means for creating a generally ring-shaped pattern of dynamic turbulence in the water relative to the center of said weight means.

Claim 3

A swimming pool cleaning apparatus, comprising: a manually portable and readily movable weight means adapted to sink in water; said weight means having horizontally disposed structure, the maximum dimensions of which equal a small fraction of the length or breadth of a swimming pool; said weight means being adapted to be manually moved and temporarily located in various desired positions relative to the sides and ends of A swimming pool and on the bottom of said swimming pool; said weight means having supporting surface means adapted frictionally to engage the bottom of a swimming pool; said supporting surface means being the only means for holding said weight means stationarily on the bottom of a swimming pool; a plurality of elongated flexible jet reactive pool cleaning tubes coupled to said weight means at an elevation above said supporting surface so as to dispose a major portion of their length engageable with the bottom of said pool; said pool cleaning tubes substantially equally spaced apart and extending generally radially away from said weight means and having a major portion of said length thereof disposed for engagement with the bottom of a pool when said weight means is supported on said bottom of said pool by said supporting surface means; a flexible water delivery conduit coupled to said weight means and extending upward generally in alignment with the center of gravity of said weight means when said weight means is resting on said supporting surface means; said water delivery conduit adapted to contain water under pressure and in communication with said jet reactive pool cleaning tubes; said jet reactive pool cleaning tubes communicating with said water delivery conduit and adapted to receive water under pressure therefrom; said jet reaction tubes each having free and open jet means substantially spaced from said weight means and adapted to issue a jet of water therefrom to thereby cause sinuous movement of said pool cleaning tube relative to said weight means and relative to the bottom and sides of said swimming pool; said weight means being of sufficient magnitude to hold said supporting surface means down in frictionally engaged stationary relationship with the bottom of said pool so that said weight means resists jet reaction forces imposed by said jet reactive pool cleaning tubes whereby said weight means remains stationary on the bottom of said pool while sinuous movement of said jet reactive pool cleaning tubes continue to operate in a manually preselected area around said weight means for cleaning the bottom and sides of said pool.

Claim 4

A swimming pool cleaning apparatus, comprising: a manually portable and readily movable weight means adapted to sink in water; said weight means having horizontally disposed structure, the maximum dimensions of which equal a small fraction of the length or breadth of a swimming pool; said weight means being adapted to be manually moved and temporarily located in various desired positions relative to the sides and ends of A swimming pool and on the bottom of said swimming pool; said weight means having supporting surface means adapted frictionally to engage the bottom of a swimming pool; said supporting surface means being the only means for holding said weight means stationarily on the bottom of a swimming pool; a plurality of elongated flexible jet reactive pool cleaning tubes coupled to said weight means at an elevation above said supporting surface so as to dispose a major portion of their length engageable with the bottom of said pool; said pool cleaning tubes substantially equally spaced apart and extending generally radially away from said weight means and having a major portion of said length thereof disposed for engagement with the bottom of a pool when said weight means is supported on said bottom of said pool by said supporting surface means; a flexible water delivery conduit coupled to said weight means and extending upward generally in alignment with the center of gravity of said weight means when said weight means is resting on said supporting surface means; said water delivery conduit adapted to contain water under pressure and in communication with said jet reactive pool cleaning tubes; said jet reactive pool cleaning tubes communicating with said water delivery conduit and adapted to receive water under pressure therefrom; said jet reaction tubes each having free and open jet means substantially spaced from said weight means and adapted to issue a jet of water therefrom to thereby cause sinuous movement of said pool cleaning tube relative to said weight means and relative to the bottom and sides of said swimming pool; said weight means being of sufficient magnitude to hold said supporting surface means down in frictionally engaged stationary relationship with the bottom of said pool so that said weight means resists jet reaction forces imposed by said jet reactive pool cleaning tubes whereby said weight means remains stationary on the bottom of said pool while sinuous movement of said jet reactive pool cleaning tubes continue to operate in a manually preselected area around said weight means for cleaning the bottom and sides of said pool.

Claim 5

The invention as defined in claim 2, wherein: the vertical extension of said water delivery conduit upwardly and in alignment with the center of said weight means provides for vertical suspension of said weight in upright position when lowering the weight means into the pool by means of said flexible water supply or water delivery conduit.
