Abstract
Abstract The disclosure relates to the features of construction of a rectangular swimming pool having an aluminum framework comprised of upper and lower rails, uprights connecting the rails and a sheet metal or plastic wall between the rails enclosing the pool area. A vinyl liner provided with a bead about its perimeter covers the sides and bottom of the pool with the bead inserted in a channeled member attached to the upper rail to overlie the upper marginal edge portion of the pool wall. The corner upright of the framework is a reinforced angled post to which is attached a curved surface with the concavity facing inwardly and having reverse curves to overlie bolts which secure the wall to the sides of the angled posts.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
137 words
A rectangular swimming pool comprised of side and end top and bottom rails with laterally spaced uprights extending between the top and bottom rails and including corner uprights, rigid pool-enclosing wall means extending between the top and bottom rails, said corner uprights each comprising a post substantially L-shaped in cross section with the included angle facing inwardly, bolts securing the outer surface of said wall means to the inner sides of the post, and a vertically extending rigid wall section having an inwardly facing concave surface lying athwart the included angle provided by each post and secured to the inner corner thereof, the wall section having side extensions which overlie the bolts and an upright channeled bar coextensive with the post with the outer surface of its bottom wall secured to the outer corner of the post.
Claim 2
Dependent Claim
137 words
A rectangular swimming pool comprised of side and end top and bottom rails with laterally spaced uprights extending between the top and bottom rails and including corner uprights, rigid pool-enclosing wall means extending between the top and bottom rails, said corner uprights each comprising a post substantially L-shaped in cross section with the included angle facing inwardly, bolts securing the outer surface of said wall means to the inner sides of the post, and a vertically extending rigid wall section having an inwardly facing concave surface lying athwart the included angle provided by each post and secured to the inner corner thereof, the wall section having side extensions which overlie the bolts and an upright channeled bar coextensive with the post with the outer surface of its bottom wall secured to the outer corner of the post.
Claim 3
Dependent Claim
20 words
A rectangular swimming pool according to claim 1 wherein said side extensions are reversely curved relative to the concave surface.
Claim 4
Dependent Claim
167 words
A swimming pool construction comprised of top and bottom rails forming enclosed figures with laterally spaced uprights extending between and secured to the top and bottom rails to provide a free-standing structural framework, rigid pool enclosing wall means supported at its lower end by said bottom rail with its upper marginal end portion lying against an outer side surface of the upper rail, and a gutter for overflow of water from the pool, comprising a depressed channel-shaped portion in the top rail along its marginal edge portion adjacent the pool, an inverted substantially L-shaped strip, the horizontal leg of said strip having a portion provided with a depressed channel portion nesting within the channel-shaped portion of the top rails and a portion overlying the upper edge of the wall means, the vertical leg of said strip extending along the upper portion of the wall means and having its bottom edge upturned to form an upwardly open channel to receive the beaded edge of a water-retaining pool line.
Claim 5
Dependent Claim
167 words
A swimming pool construction comprised of top and bottom rails forming enclosed figures with laterally spaced uprights extending between and secured to the top and bottom rails to provide a free-standing structural framework, rigid pool enclosing wall means supported at its lower end by said bottom rail with its upper marginal end portion lying against an outer side surface of the upper rail, and a gutter for overflow of water from the pool, comprising a depressed channel-shaped portion in the top rail along its marginal edge portion adjacent the pool, an inverted substantially L-shaped strip, the horizontal leg of said strip having a portion provided with a depressed channel portion nesting within the channel-shaped portion of the top rails and a portion overlying the upper edge of the wall means, the vertical leg of said strip extending along the upper portion of the wall means and having its bottom edge upturned to form an upwardly open channel to receive the beaded edge of a water-retaining pool line.
Claim 6
Dependent Claim
28 words
A swimming pool according to claim 3 wherein said upper rail is provided with locking means cooperating with said strip for retaining the channel-shaped portions in nested relation.
Claim 7
Dependent Claim
