Abstract
Abstract A water conduit connector which is particularly adapted to connect a water conduit to the wall of a swimming pool in a water-tight manner, the swimming pool being formed of an outer rigid sheet material layer and an interior plastic water-tight layer, the connector including a cylindrical tubular member extending through an opening through both of the interior layer and the outer layer, an annular collar extending from the tubular member and located between the interior layer and the outer layer, a washer to surround the tubular member and adapted to come into contact with the interior layer and frictionally bind such to the annular collar, the washer including a plurality of spaced apart radial ridges to resist rotational movement between the washer and the interior layer, a lock nut to be engaged with the tubular member and be in contact with the washer, the lock nut including a plurality of concentrically disposed rings which are to contact the washer and upon such being tightened, a minimal amount of torque is created tending to rotate the washer.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
156 words
In combination with the wall of a swimming pool, said wall being constructed of a rigid outer sheet material layer and an interior flexible water-tight layer, an opening extending through said outer layer and said interior layer, a water conduit located adjacent said opening, a water conduit connector comprising: a tubular member to connect with said water conduit and extend entirely through said opening, said tubular member having a first means located between said outer sheet material layer and said interior water-tight layer; a washer surrounding said tubular member having an interior surface and an exterior surface, said interior surface to contact said interior layer, said interior surface having second means thereon for resisting rotational movement relative to said interior layer; and a lock nut surrounding and engaging said tubular member, said lock nut including a third means to contact said washer and be capable of forcing said washer into frictional contact with said interior layer.
Claim 2
Dependent Claim
156 words
In combination with the wall of a swimming pool, said wall being constructed of a rigid outer sheet material layer and an interior flexible water-tight layer, an opening extending through said outer layer and said interior layer, a water conduit located adjacent said opening, a water conduit connector comprising: a tubular member to connect with said water conduit and extend entirely through said opening, said tubular member having a first means located between said outer sheet material layer and said interior water-tight layer; a washer surrounding said tubular member having an interior surface and an exterior surface, said interior surface to contact said interior layer, said interior surface having second means thereon for resisting rotational movement relative to said interior layer; and a lock nut surrounding and engaging said tubular member, said lock nut including a third means to contact said washer and be capable of forcing said washer into frictional contact with said interior layer.
Claim 3
Dependent Claim
30 words
The combination as defined within claim 1 wherein: said tubular member being cylindrical in configuration, said first means comprises an enlarged annular collar extending radially outward from said tubular member.
Claim 4
Dependent Claim
27 words
The combination as defined within claim 2 wherein: the surface of said collar which is in contact with said interior water-tight layer being substantially smooth in cOnfiguration.
Claim 5
Dependent Claim
105 words
The combination as defined within claim 3 including: said tubular member being externally threaded, a clamp ring to engage said threaded tubular member, said clamp ring having an engaging surface to contact said rigid outer sheet material layer and effect clamping of said outer sheet material layer between said collar and said clamp ring, said engaging surface of said clamp ring including a plurality of spaced apart concentric ridges, whereby said clamp ring upon being forced into frictional engagement with said outer layer a minimum amount of torque is created which tends to result in rotation of said tubular member relative to said outer layer.
Claim 6
Dependent Claim
20 words
The combination of claim 4 wherein: said tubular member being fixedly secured in a permanent manner to said water conduit.
Claim 7
Dependent Claim
52 words
The combination as defined in claim 3 wherein: said second means omprises a plurality of radial, spaced apart ridges, whereby said ridges tend to frictionally bind said flexible water-tight layer to said smooth surface of said collar, thereby tending to resist rotational movement of said washer relative to said flexible water-tight layer.
Claim 8
Dependent Claim
20 words
The combination as defined in claim 6 wherein: said radial ridges being located between a plurality of concentrically located ridges.
Claim 9
Dependent Claim
18 words
The combination as defined in claim 7 wherein: said third means comprises a plurality of concentrically located ridges.
