Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 208 words
A composite protective coping member for a swimming pool, comprising an elongated rigid moulded body of uniform cross sectional shape having longitudinally extending front and rear edges, the body being constituted by a body portion of dispersedfibre reinforced plastic material having an outer skin portion constituted by a layer of matted fibres impregnated with said plastic material and integrally moulded therewith, the skin defining a longitudinally extending, contoured frontal portion of substantial thickness and a horizontal relatively thin flanged portion extending rearwardly therefrom, the contoured frontal portion having a convex upper surface defining a raised kerb, raised relative to said flanged portion, and a retainer member for a swimming pool liner, the retainer member being constituted by a metallic member having a keyed upper portion embedded in and fixedly anchored to said body portion and a flanged lower portion defining a longitudinally extending channel facing said frontal portion and adapted to receive the edge of the liner, said horizontal flanged portion having a horizontal lower surface adapted to lie on a floor structure, the frontal portion having a longitudinally stepped lower surface providing a horizontal lower surface of the flanged portion and a raised surface portion and having a horizontal base flange coplanar with said lower surface portion.
Claim 2
Dependent Claim 208 words
A composite protective coping member for a swimming pool, comprising an elongated rigid moulded body of uniform cross sectional shape having longitudinally extending front and rear edges, the body being constituted by a body portion of dispersedfibre reinforced plastic material having an outer skin portion constituted by a layer of matted fibres impregnated with said plastic material and integrally moulded therewith, the skin defining a longitudinally extending, contoured frontal portion of substantial thickness and a horizontal relatively thin flanged portion extending rearwardly therefrom, the contoured frontal portion having a convex upper surface defining a raised kerb, raised relative to said flanged portion, and a retainer member for a swimming pool liner, the retainer member being constituted by a metallic member having a keyed upper portion embedded in and fixedly anchored to said body portion and a flanged lower portion defining a longitudinally extending channel facing said frontal portion and adapted to receive the edge of the liner, said horizontal flanged portion having a horizontal lower surface adapted to lie on a floor structure, the frontal portion having a longitudinally stepped lower surface providing a horizontal lower surface of the flanged portion and a raised surface portion and having a horizontal base flange coplanar with said lower surface portion.
Claim 3
Dependent Claim 27 words
A composite protective coping member according to claim 1, wherein the materials of said body portion and said skin portion are glass fibre reinforced thermosetting plastic materials.
Claim 4
Dependent Claim 17 words
A composite protective coping member according to claim 2, wherein the retainer member is an aluminum extrusion.
Claim 5
Dependent Claim 35 words
A composite protective coping member according to claim 1, wherein said base flange has an upwardly projecting, longitudinally extending, terminal lip defining one edge of the liner-retaining channel and providing an anchorage for the liner.
Claim 6
Dependent Claim 23 words
A composite protective coping member according to claim 4, wherein the terminal lip is spaced rearwardly from the front edge of the body.
Claim 7
Dependent Claim 39 words
A composite protective coping member according to claim 5, wherein the rear edge of the horizontal flanged portion of the body has a downturned terminal flange adapted to be secured to a vertical wall surface of said floor structure.
