Abstract:
1. An improved method for angularly orienting and securing two longitudinal swimming pool extrusions each having a longitudinal pool-liner anchor channel with an upward projecting liner-anchoring land along a bottom front edge defining an entrant slot into the pool-liner anchor channel for framing a desired corner for incorporation into walls of a swimming pool during construction, comprising the steps of: a) making a bottom plate with top, and bottom faces having straight, planar, intersecting side-edges defining the desired corner and a planar concave-curved pool side-edge crossing between the straight planar intersecting side edges; b) milling a planar, concave-curved, relief into the top face of the bottom plate spaced inward from, and parallel to the concave curved pool side-edge of the bottom plate having a depth at most equal to the cross-sectional height of the pool liner channels and a width at most equal to the cross-sectional width of the pool-liner anchor channel and providing an upward projecting corner pool-liner-anchoring land at the concave-curved planar pool side-edge of the bottom plate; and c) milling linear side-reliefs into the planar, straight intersecting side-edges of the bottom plate with a deeper base slot for providing extending, side-shoulders with vertical seating faces, the side-shoulders being sized for snugly sliding longitudinally within the respective pool-liner anchor channels of the extrusions with the deeper base slot receiving the upward projecting pool-liner anchoring lands along the bottom front edge of the pool-liner anchor channels with the vertical seating faces of the side-shoulders seated on facing surfaces of the respective swimming pool extrusions below the entrant slots into the pool-liner anchor channels of the swimming pool extrusions; d) sliding the longitudinal extrusions onto the bottom plate with the respective extending side-shoulders of bottom plate each being received in a pool-liner anchor channel of one of the extrusions to frame the desired corner; e) removing sections of the upward projecting pool-liner anchoring land of the extrusion pool-liner anchor channels framing the corner that cross the planar, curved liner-relief milled into the top surface of the bottom plate when the extending side shoulders of the bottom plate are received in the swimming pool extrusion pool-liner anchor channels for framing the desired corner; f) making a top plate having a planar bottom face, and straight planar side-edges defining the corner with a concave-curved pool side-edge, conforming to that of the planar concave-curved pool side-edge of the bottom plate, the top plate being sized to seat on the top face of the bottom plate with its straight planar side-edges seating on facing front surfaces of the respective longitudinal extrusions above the entrant slots into the pool-liner anchor channels of the corner framing swimming pool extrusions and with its concave-curved pool side-edge in vertical registry with the planar concave-curved pool side edge of the bottom plate for providing a corner pool-liner anchor channel aligned with the respective pool-liner channels of the corner framing swimming pool extrusions in combination with the planar, concave-curved, relief milled into the top face of the bottom plate; and g) securing the top plate to the bottom plate.
