Abstract
Abstract A plurality of freely rotating wear rings are disposed along a flexible whip hose of the type used for cleaning swimming pools. The rotating wear rings prevent the flexible whip hose from being abraded by the inner surfaces of a swimming pool. The rotating wear rings have long lives, as their rotation precludes significant abrasion upon the inner surfaces of the swimming pool.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
157 words
A rotational device for use on a flexible whip hose for cleaning a swimming pool, said rotational device comprising in combination: (a) rotating means concentrically disposed about said flexible whip hose for rolling along interior surfaces of the swimming pool while supporting said flexible whip hose to prevent abrading of said flexible whip hose by the interior surfaces, said rotating means including a cylindrical collar having at least one tapered end; and (b) bearing means concentrically disposed on and frictionally engaging said flexible whip hose for axially and rotatably supporting said rotating means, said bearing means including a first cylindrical tubular shaft concentrically disposed about and frictionally engaging said flexible whip hose and having an outside diameter less than the inside diameter of said cylindrical collar, the difference between said outside diameter and said inside diameter being a predetermined tolerance dimension selected to permit substantially free rotation of said cylindrical collar about said first cylindrical tubular shaft.
Claim 2
Dependent Claim
157 words
A rotational device for use on a flexible whip hose for cleaning a swimming pool, said rotational device comprising in combination: (a) rotating means concentrically disposed about said flexible whip hose for rolling along interior surfaces of the swimming pool while supporting said flexible whip hose to prevent abrading of said flexible whip hose by the interior surfaces, said rotating means including a cylindrical collar having at least one tapered end; and (b) bearing means concentrically disposed on and frictionally engaging said flexible whip hose for axially and rotatably supporting said rotating means, said bearing means including a first cylindrical tubular shaft concentrically disposed about and frictionally engaging said flexible whip hose and having an outside diameter less than the inside diameter of said cylindrical collar, the difference between said outside diameter and said inside diameter being a predetermined tolerance dimension selected to permit substantially free rotation of said cylindrical collar about said first cylindrical tubular shaft.
Claim 3
Dependent Claim
38 words
The rotational device of claim 1 wherein said bearing means further includes first retaining means disposed at one end of said first cylindrical tubular shaft for preventing said cylindrical collar from sliding off said first cylindrical tubular shaft.
Claim 4
Dependent Claim
22 words
The rotational device of claim 2 wherein said first retaining means is integral with one end of said first cylindrical tubular shaft.
Claim 5
Dependent Claim
58 words
The rotational device of claim 3 wherein said bearing means further includes a second cylindrical tubular shaft substantially identical to said first cylindrical shaft and having said second retaining means integral therewith, said second cylindrical tubular shaft being concentrically disposed on and frictionally engaged to said flexible whip hose to further axially and rotatably support said cylindrical collar.
Claim 6
Dependent Claim
18 words
The rotational device of claim 3 wherein said bearing means and said rotating means are composed of nylon.
Claim 7
Dependent Claim
36 words
The rotational device of claim 2 further including second retaining means for preventing said cylindrical collar from sliding off said first cylindrical tubular shaft, said second retaining means including a nozzle for said flexible whip hose.
Claim 8
Dependent Claim
97 words
A rotational device for use on a flexible whip hose for cleaning a swimming pool, said rotational device comprising in combination: (a) rotating means concentrically disposed about said flexible whip hose for rolling along interior surfaces of the swimming pool while supporting said flexible whip hose to prevent abrading of said flexible whip hose by the interior surfaces; and (b) bearing means concentrically disposed on and frictionally engaging said flexible whip hose for axially and rotatably supporting said rotating means, said bearing means including an interior detent for increasing the frictional engagement of said flexible whip hose.
Claim 9
Dependent Claim
97 words
A rotational device for use on a flexible whip hose for cleaning a swimming pool, said rotational device comprising in combination: (a) rotating means concentrically disposed about said flexible whip hose for rolling along interior surfaces of the swimming pool while supporting said flexible whip hose to prevent abrading of said flexible whip hose by the interior surfaces; and (b) bearing means concentrically disposed on and frictionally engaging said flexible whip hose for axially and rotatably supporting said rotating means, said bearing means including an interior detent for increasing the frictional engagement of said flexible whip hose.
Claim 10
Dependent Claim
111 words
A whip hose assembly for use in conjunction with swimming pool cleaning systems, said whip hose assembly comprising in combination: (a) a flexible whip hose; and (b) a plurality of rotational wear ring devices disposed in spaced relationship along said flexible whip hose, each of said rotational wear ring devices including i. rotating means concentrically disposed about said flexible whip hose for rolling along interior surfaces of the swimming pool while supporting said flexible whip hose to prevent abrading of said flexible whip hose by the interior surfaces; and ii. bearing means concentrically disposed on and frictionally engaged to said flexible whip hose for axially and rotatably supporting said rotating means.
Claim 11
Dependent Claim
111 words
A whip hose assembly for use in conjunction with swimming pool cleaning systems, said whip hose assembly comprising in combination: (a) a flexible whip hose; and (b) a plurality of rotational wear ring devices disposed in spaced relationship along said flexible whip hose, each of said rotational wear ring devices including i. rotating means concentrically disposed about said flexible whip hose for rolling along interior surfaces of the swimming pool while supporting said flexible whip hose to prevent abrading of said flexible whip hose by the interior surfaces; and ii. bearing means concentrically disposed on and frictionally engaged to said flexible whip hose for axially and rotatably supporting said rotating means.
Claim 12
Dependent Claim
144 words
A rotational device for use on a flexible whip hose for cleaning a swimming pool, said rotational device comprising in combination: (a) rotating means concentrically disposed about said flexible whip hose for rolling along interior surfaces of the swimming pool while supporting said flexible whip hose to prevent abrading of said flexible whip hose by the interior surfaces; and (b) bearing means concentrically disposed on and frictionally engaging said flexible whip hose for axially and rotatably supporting said rotating means, said bearing means including a first cylindrical tubular shaft concentrically disposed about and frictionally engaging said flexible whip hose and having an outside diameter less than the inside diameter of said cylindrical collar, the difference between said outside diameter and said inside diameter being a predetermined tolerance dimension selected to permit substantially free rotation of said cylindrical collar about said first cylindrical tubular shaft.
Claim 13
Dependent Claim
144 words
A rotational device for use on a flexible whip hose for cleaning a swimming pool, said rotational device comprising in combination: (a) rotating means concentrically disposed about said flexible whip hose for rolling along interior surfaces of the swimming pool while supporting said flexible whip hose to prevent abrading of said flexible whip hose by the interior surfaces; and (b) bearing means concentrically disposed on and frictionally engaging said flexible whip hose for axially and rotatably supporting said rotating means, said bearing means including a first cylindrical tubular shaft concentrically disposed about and frictionally engaging said flexible whip hose and having an outside diameter less than the inside diameter of said cylindrical collar, the difference between said outside diameter and said inside diameter being a predetermined tolerance dimension selected to permit substantially free rotation of said cylindrical collar about said first cylindrical tubular shaft.
