Abstract
Abstract A swimming pool construction of the below ground type includes a peripheral side and bottom wall structure composed of a plurality of generally rectangular planar members in edge-to-edge abutment and having inner and outer surfaces bearing an attached sheath, skin or layer of continuous unbroken character and composed of woven fiber glass cloth impregnated with a suitable resin such as a polyester resin and said inner and outer layers having their upper and lower marginal edges in overlapped relationship to completely encapsulate said planar core and said wall further including a continuous upper edge and lower edge stiffener serving together and with said planar wall core to lend unique integral strength.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
130 words
A pool construction of the below ground level type and having a bottom wall and marginally connected, vertically upstanding linear side and end walls disposed to, in concert, define a polygonal, water-tight enclosure for the water in said pool, said side and end walls each having a lower edge defining a seam with said bottom wall and an upper edge, said side and end walls including: a center core formed of a plurality of planar members arranged in mutual edge-to-edge aligned abutment to form the linear extent of said walls and a layer of resin-impregnated fiber glass bonded to each planar opposed surface of said wall in a manner to completely encapsulate said linear array of core panels to provide a water proof barrier and means for sealing said seams.
Claim 2
Dependent Claim
130 words
A pool construction of the below ground level type and having a bottom wall and marginally connected, vertically upstanding linear side and end walls disposed to, in concert, define a polygonal, water-tight enclosure for the water in said pool, said side and end walls each having a lower edge defining a seam with said bottom wall and an upper edge, said side and end walls including: a center core formed of a plurality of planar members arranged in mutual edge-to-edge aligned abutment to form the linear extent of said walls and a layer of resin-impregnated fiber glass bonded to each planar opposed surface of said wall in a manner to completely encapsulate said linear array of core panels to provide a water proof barrier and means for sealing said seams.
Claim 3
Dependent Claim
22 words
A pool construction as claimed in claim 1, wherein said walls include stiffener means extending the entire linear extent of said wall.
Claim 4
Dependent Claim
32 words
A pool construction as claimed in claim 2, wherein said stiffener means is a length of material more rigid than said core extending along the upper outer surface edge of said wall.
Claim 5
Dependent Claim
31 words
A pool construction as claimed in claim 2, wherein said stiffener means is a length of material more rigid than said core extending continuously along the bottom edge of said pool.
Claim 6
Dependent Claim
32 words
A pool construction as claimed in claim 4, wherein said stiffener means includes a length of material more rigid than said core extending along the upper outer surface edge of said wall.
Claim 7
Dependent Claim
19 words
A pool construction as claimed in claim 1, wherein said fiber glass is in the form of woven cloth.
Claim 8
Dependent Claim
14 words
A pool construction as claimed in claim 1, wherein said central core is plywood.
Claim 9
Dependent Claim
34 words
A pool construction as claimed in claim 4, wherein said length of material includes an upwardly facing linear groove and the bottom edges of said side-by-side wall panels are snugly fitted in said groove.
Claim 10
Dependent Claim
33 words
A pool construction as claimed in claim 8, wherein said stiffener means includes an integral flange extending along said wall and serving as a seat for the marginal edge of said bottom wall.
Claim 11
Dependent Claim
48 words
A pool construction as claimed in claim 3, wherein said wall includes a plurality of bolts secured in said wall and extending through said wall proximate the upper edge and through the said upper stiffener member to extend outwardly for convenient engagement or abutment in appropriate anchor means.
Claim 12
Dependent Claim
16 words
A pool construction as claimed in claim 5, wherein said fiber glass is a woven cloth.
Claim 13
Dependent Claim
