A form system for a fiberglass or vinyl-lined swimming pool utilizes an elongate pliable form, a bracket, a spear, and a button mounted on the spear to secure the bracket in position against the form. The bracket and form are shaped and dimensioned such that when the bracket placed against the form, it conforms to the form, it is automatically properly positioned to receive the spear, to support the form in the desired position with respect to the bracket, and to generate a compression vector, VC, which frictionally secures the bracket to the wall of the swimming pool. |

1. A form system for a swimming pool having a substantially vertically extending pool wall circumscribing an interior reservoir space and including
a top including an upper edge, and, an inner surface extending downwardly from said upper edge and comprised of a material selected from a group consisting of fiberglass and vinyl,said system comprising(a) an elongate form of a semirigid material
(i) having a longitudinal length, (ii) pliable along said longitudinal length, (iii) substantially rigid transverse of said longitudinal length, (iv) having a contoured face to form a deck coping, said contoured face extending at least in part over said interior reservoir space, (v) having a substantially vertical back spaced apart from and opposed to said face, (vi) having a longitudinal lip below said contoured face and conforming to and contacting said upper edge, (vii) having a bottom surface, (viii) having a horizontally oriented reference line extending across said back, and (ix) extending outwardly from said pool wall over the interior reservoir space;(b) a bracket including
(i) a vertically oriented head with
an inner surface contacting said back of said form, said inner surface shaped and dimensioned to conform to and support said back of said form, andan aperture extending through said head, (ii) a leg
having an upper end connected to said head,extending beneath said form downwardly from said head at an angle A to the pool wall,having a lower end, andcontacting and supporting said bottom surface of said form, (iii) a foot connected to and extending outwardly from said lower end of said leg and frictionally non-fixedly contacting said inner surface of said pool wall;(c) an elongate spear
(i) having a head secured in position above the top of the pool wall, (ii) including a leg extending through said elongate form, said leg having a serrated end extending through and outwardly away from said vertical back through said aperture in said head of said bracket;(d) a locking button fixedly slidably mounted on said serrated end and against said head to compress said form against the pool wall,said angle between said leg and the pool wall being in the range of twenty degrees and sixty degrees such that said foot generates a compression force vector, VC, to(e) press said foot against the pool wall, and(f) increase frictional engagement between said foot and the pool wall sufficiently to maintain said foot in position on the pool wall and support said form when concrete contacts said contoured face extending over said interior reservoir space;said form and said bracket being shaped and dimensioned such that when said serrated end of said spear passes through said aperture in said bracket, said leg of said bracket contacts said bottom of said form and supports said form. |
