Abstract: The invention contemplates an improved construction of the reinforced ends of flexible sheet-metal panels used in defining the basic generally cylindrical wall to be lined with flexible material in the erection of a prefabricated swimming pool. The end-reinforcement structure uses substantially thinner-gage material than heretofore, and yet a secured joint of two lapped panel ends has the hoop-tension resistance of the best of previous constructions without presenting any ambiguity regarding the sense (i.e., overlapped relation of parts) at the overlap.

Abstract: A prefabricated swimming pool includes a liner and a wall supported by vertical posts. Lip members are arranged between the posts along the top edge of the wall and connected to the posts by brackets. The angles at which the lip members are attached to the posts are adjustable so that the number of posts used to support the wall can be varied, and pools of differing sizes can be constructed using standard components.
