Abstract
Abstract A flexible hose particularly suitable for use with automatically operated swimming pool cleaners, the hose being blow moulded from suitable plastics material such that separate lengths can be cut with each length having an integral coupling component at each end. Preferably there will be a male component at one end and a female component at the other end.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A length of flexible hose of corrugated form with walls of generally constant thickness connected to an integral male coupling component at one end and a female coupling component at the other end, the male coupling component having a plurality of outwardly extending rings spaced apart along the length thereof of decreasing diameter towards the free end and the female coupling component providing a sleeve to extend over the male coupling component and the male coupling component is more rigid than the female coupling component defining a means allowing said female coupling component to deflect inwardly in response to reduced fluid pressure to provide a seal between said female coupling component and said male coupling component.
Claim 2
Dependent Claim
116 words
A length of flexible hose of corrugated form with walls of generally constant thickness connected to an integral male coupling component at one end and a female coupling component at the other end, the male coupling component having a plurality of outwardly extending rings spaced apart along the length thereof of decreasing diameter towards the free end and the female coupling component providing a sleeve to extend over the male coupling component and the male coupling component is more rigid than the female coupling component defining a means allowing said female coupling component to deflect inwardly in response to reduced fluid pressure to provide a seal between said female coupling component and said male coupling component.
Claim 3
Dependent Claim
39 words
A length of flexible hose as claimed in claim 1 wherein the male coupling component is more radially rigid than the female coupling component, which comprises a flexible planar sleeve that grips the male coupling component at ambient pressure.
Claim 4
Dependent Claim
40 words
A length of flexible hose as claimed in claim 1 wherein each ring of the male coupling component provides a plurality of triangular cross-sectional peaks that provide a substantially peripheral line contact surface for engagement with the female coupling component.
Claim 5
Dependent Claim
35 words
A length of hose as claimed in claim 1 wherein the male coupling component has a serrated longitudinal profile and the female coupling is in the form of a sleeve having a plane inner surface.
Claim 6
Dependent Claim
48 words
A length of flexible hose as claimed in claim 1 in which the male coupling component carries a plurality of rings spaced apart the free peripheries of which are of narrow cross section and the female coupling component is in the form of a thin walled planar sleeve.
Claim 7
Dependent Claim
20 words
A length of flexible hose as claimed in claim 5 in which the rings are of generally triangular cross-sectional shape.
Claim 8
Dependent Claim
25 words
A length of flexible hose as claimed in claim 6 in which each ring provides a pair of peripheral substantially line contact surfaces spaced apart.
Claim 9
Dependent Claim
28 words
A length of hose as claimed in claim 1 wherein the coupling components are tapered complimentarily and the angle of the taper is between 1° and 4° .
Claim 10
Dependent Claim
26 words
A length of flexible hose as claimed in claim 1 wherein the walls of the male and female coupling components can be made of variable thickness.
